Description: INSULATING APPARATUS AND COMPOSITE LAMINATES EMPLOYED THEREIN CROSS REFERENCE TO RELATED APPLICATIONS The substance of this invention appears in O. ^ . application Serial No. 282,709 3 which is a continuation of our. copeήding application Serial No. 102,552 filed December 11, 1979; which is, in turn, a continuation-in-part of appli¬ cation Serial No. 912, 7^ filed June 5, 1278. OMPI INSULATING APPARATUS AND COMPOSITE LAMINATES EMPLOYED THEREIN TECHNICAL FIELD This invention pertains to insulating and security apparatus and composite laminates employed therein. BACKGROUND ART This invention relates to a transaction processing enclosure wherein the housing or walls, ceiling and floor are formed of a selectively light-weight, composite laminate adapted for containment of electronic data processing equip- ment, banking apparatus, and other and related electrical an electronic equipment, and providing thereto a sustained insu ated environment substantially immune to impact, for example, from bullets and projectiles, and to flame, smoke and extreme variations in temperature in the atmosphere external to the enclosure. In general, heretofore, the exterior walls of, for example, buildings have been, insulated with loosely packed, bulky materials such as fiberglass, which offer little fire protection. The us-e of asbestos employed occasionally to insulate girder bars, has abated because of the health hazard it poses. Furthermore, the contact between the surfaces of a building wall and supporting girders has been through direct metal to metal contact using metallic fastening elements such as rivets. Similarly, conventional interior building walls have been constructed using gypsum (CaSO^.^O) or similarly low co mineral material clad in fire resistant papers with a dull finish. More commonly, gypsum board has been used in standard size sheets and attached to intermittently disposed steel supports, with metal studs driven through the insulating material. These walls are, normally, fabricated however, at the construction site. They are permanent and not readily reusable or relocatab-le. The gypsum insulating elements have, typically, a density of 2.31-2.33 grams per cubic centimeter, thermal conductivities ranging from 3 to 9 BTU per hour per square foot per degree Fahrenheit per inch thickness, and total emissivity greater than 0,95. The use of conventional metal fastening elements facilitates heat transfer to the supports, as well. The construction of the fuselage of aircraft, and, more recently, space craft, and the like including wings, where present, and engine compartments has, at the same time ' undergone a revolution in design over the past several decades resulting in a variety of different structures. Initially, for example, low altitude, low speed aircraft had simple metal skins supported at intervals with a contoured metallic frame. As standard altitudes and speeds have increased, the require¬ ment for maintenance of an ever increasing temperature gradient between the interior and exterior of the craft has also meas¬ urably increased. At the same time, simultaneous need for a decrease in weight and an increase in structural strength has resulted in a variety of innovations, centering about two basic structural variations, the "honeycomb" design and the composite wall design. The "honeycomb" design refers to the joining of inner and outer wall elements, most commonly metal's, using inter- spersed connection elements-, usually metals, fastened using rivets or similar agents. Recently, some adhesive systems have been developed which have had varied success in joining the elements of the skin wall together. However, few can withstand prolonged exposure to . temperatures over 200°C. and most bonds formed by the adhesives tend to weaken with vibra- tional stress and exposure to moisture. Similarly, metal to metal contact is present through the elements of the structure. The composite walls usually involve the joining of inner and outer metallic layers, with insulating materials disposed between them and supporting structural elements inter¬ mittently disposed therein in the form of ribs or struts. The insulating layers have rarely Been bonded with success to the metallic layers and have not added significantly to the strength of the wall or,skin so formed, in any event. Commonly, the supporting elements are also bound by metal to metal con¬ tact using rivets or other suitable fasteners .to inner and outer metallic layers. Use of adhesives in this application, to join the metal surfaces and the supporting elements have similar limitations to those described above; that is low thermal resistance, sensitivity to vibration and bond sensi¬ tivity to moisture t In most embodiments-, the metal to metal contact between the inner and outer layers is- reduced but not eliminated. In a significantly disparate area from that of aircraf fuselage design and construction, the vaults commonly employe to guard currency, other valuables including jewelry, securities-, documents of importance and the like, have common been bulky structures with relatively thick walls. Most majo bank vaults, for example, have concrete walls several inches to several feet in thickness to protect the contents from thermal damage in event of fire and to discourage and hamper forceful entry into the interior thereof by miscreants, vanda felons and the like. Ceramic compositions in fiber form, have also been use extensively heretofore as insulating or refractory materials in furnace walls and the like. These compositions may be utilized in randomly dis-tributed fibrous form as well as in embodiments wherein the fibers are linked to form blankets, paper, felt, or fabric. Many ceramic fibers are composites containing varying amounts of silicon oxide (SiO ) and aluminu oxide or alumina CAl 2 0 ) as well as small amounts of other oxides such as sodium oxide (Na^O), boron oxide (B O and iron oxide e 2 0_). Increasing the alumina content generally increases the thermal resistance of the refractory fiber. The preparation of a refractory glass wool useful as an insulation material and incorporating alumina and silica is disclosed in U.S. patent 2,557 J 83 1 1. Colloidal silica as a coating cement for graphite, metals and refractories is described in U.S. patent 3,231, 01. Other ceramic fibrous f materials containing chiefly zirconium oxide (Zr0 2 ) halnium oxide (Hf0 2 ) and yttrium oxide (YOg) have also been used as insulating and refractory mater- ials in the various forms " recited hereinabove .and, indeed, have, generally, superior refractory properties. Thorium oxide ( . ThO p ) and tantalum oxide _ ~ .0_- \ 3 have also been employed for these purposes. Ceramic fiber forms such as the foregoing are character- istically pliable, and easily folded, cut, or rolled. However, treatment of these ceramic fibrous refractory materials with, illustratively, an aqueous solution containing a concentrated solution of the major component oxide in combination with additional amounts of a particular oxide: evaporation of the water present and drying 'of the fibers produces a non-pliant or rigid ceramic fiber form. Solutions such as the foregoing are appropriately termed rigidizers and are well-known to those skilled in the art. Further illustrating the development of this field, U.S. patent 3,385,915 recites a procedure to form fibers and articles including a variety of metal oxides; U.S. patent 3,663,182 recites a method for the formulation of metal oxide containing fabrics;-U.S. patent 3,860,529 recites means to render ceramic fibers composed mainly of Zr0 2 stable at tem¬ peratures of 1000°F or greater; and U.S.- patent 3,861,9 7 recites means to render zirconia fibers more thermally resis- tant by coating them with amorphous silica and reacting the two components. Refractory ceramic fiber materials, that is refractory materials or compositions of ceramic character, have been effectively employed to insulate walls of high temperature furnaces; as linings- for molds to accept molten metals, espe¬ cially aluminum; to protect high temperature components in combusion chambers, such as fuel nozzles; and in applications to seal entry points for cables and conduits entering areas of high temperature, such as furnaces and nuclear reactors. In the foregoing applications the ceramic fiber refrac¬ tory materials have either been mechanically applied or cemented to surfaces to be protected thereby. Thus, U.S. patent 3,736,160 describes a fibrous zirconium oxide in a cement matrix containing zirconium oxide and a refractory powder; and U.S. patent 3,709,717 and U.S. patent 3,875,971 employ porcelain enamels for bonding zirconium oxide containing refractory ceramic fibers to metals. Other developments in the field have centered on con¬ tainers for temporary- storage and transplant of materials requiring maintenance at extremely lowtemperatures. A material effort in this area have involved improvements in vacuum Insula tion. Thus, U.S. patents 3,357,586, 3,007,596, and 3,009,600 are directed to the use of composite insulation systems in combination with a vacuum. U.S. patents 3,108,706 and 2,900,800 deal with the elimination of gaseous hydrogen evolved from the metals form¬ ing the double walls of insulation containers and accumulated in the vacuum space provided between the foregoing walls. 5 At the same time while the refractory ceramic fibers are useful in construction of relatively, thin-walled component • as described, illustratively, in U.S. patent 3,709,710 referre to hereinabove, that are capable of providing effective therma barriers for many purposes, the load placed on these component 0 is often exceedingly high, however, in that it does not pro¬ vide for absorption of the radiant heat to which the ceramic fibrous materials are normally exposed. Other intumescent refractory compositions possessed of a low thermal conducti¬ vity are also well-known.to provide seals for cable penetratio through successive floors of buildings and, illustratively, on the interior surfaces of appliances such as hair dryers wherei a limited source of intermittent heat is present. These refra ory intumescent materials are available for use in a variety of compositions including paints, coating and the like. It is known to provide closely controlled insulated environments- for electronic data processing equipment (other than, remotely disposed terminals and the like) by placing all of anOrganization's data processing equipment In a single large room where overall conditions are maintained substan- tially uniform, such as referred to hereinabove, and not by use of ceramic fiber panels. The construction of these thick, usually permanent and flame resistant walls is expensive; the location of the equipment is ' often inconvenient and not adap¬ table to change even where initially convenient and an accom- modation to necessity rather than efficient utilization. A ■ power failure, or the like, will necessitate, in the absence of an auxiliary power supply a shut-down of an organization's entire electronic data processing system; and in modern terms, where, for example, banks are concerned, will cause closing of the entire business enterprise as well as other enterprises dependent upon it. This vulnerability exists, as well, with sensitive government installations. The foregoing disadvantages have been overcome to a material degree by the provision of transaction processing enclosures or modules for housing electronic data processing equipment and the like, generally cylindrical in horizontal section, in a particularly preferred embodiment. These readil movable modules or transaction processing centers are describe - in detail hereinafter and in copending application Serial No. 952,782 filed October 19, 19.78, a divisional application of the United States patent 4,121,523 of one of the applicants herein (and both of which are incorporated by reference . herein), but the use of, for example, steel or the like alone in the walls or housing of these modules, while providing an adequate protective means for many purposes, manifests signi¬ ficant disadvantages-. Aside from the obvious concern with thermal conductivity, radio frequency energy and the like imparted by an exclusively steel or other metallic wall, for example, the opportunit to protect the interior of the booth from unauthorized penetration by means of drilling tools or the like is significantly reduced, or eliminated in many instances, as dis-closed hereinafter. In the event, therefore, that a strong integrated laminate could be devised that would incorporate reduced weight and significant flame and impact resistance and enhanced structural strength under advers-e environmental conditions and even at extremely reduced and elevated temperatures and would at the sane time prevent, substantially, the passage of ' radiant and conductive heat, a significant advance in the state of the art would be attained. Further, if a module or booth could be devised providing containment for one or more units of electronic data process¬ ing equip-ent, banking apparatus, and the like, under which a controlled environment could be assured within the module and under even the most vigorous conditions of temperature and humidity external to the booth, and afford protection against impact and fire while affording structural strength, protection simultaneously, for information, stored for example, on mag¬ netic tape and solid-state elements present in the equipment r έ disposed in the module against the influence of external radio frequency energy and, indeed, electromagnetic fields of all frequencies and concentrations, and comply with vigorous gov¬ ernmental requirements in these regards, a further advance of 5'equivalent significant dimensions in the .state of the art would be secured. In addition, were the booth housing and laminate adapte to sustain an electrical charge in certain of the plies consti tuting the enclosure housing and laminate in connection with 0 a power source and alarm to provide alarm upon unauthorized penetration thereof a still further and material step forward in the art would be achieved. It is an object of the invention therefore to provide an improved thermal barrier, panel or housing combining low conductivity and high resistance to transfer of radiant heat with an extremely broad temperature range of the order of from about -273° Centigrade QC ) to about 3200°C. It Is an additional object of this invention to provide a light-weight, impact-resistant structurally strong, firmly Integrated laminate capable of preventing transmission of both high and low frequency radiant energy in even high concen¬ trations therethrough. A further object of the invention is the provision of an enclosure, housing and laminate, incorporating means for providing notice and alarm in response to attempts to efforts to penetrate the foregoing apparatus. It is a still further, and particular object of the present invention to provide a flame retardant, impact- resistant, structurally strong, module or enclosure for incor- poration of electronic data processing equipment, electrically or electronically operated banking equipment and the like, including information retrieval systems using magnetic tape and solid state elements or chips that will be protected from either or both, high or low radio frequency energy in both high and low concentrations; with maintenance of a desired stable atmosphere within the module or enclosure despite dramatic variations in temperature, relative humidity and the like exterior thereto. The foregoing and other obj ectives and advantages of the invention will become more apparent from the description appearing hereinafter in conjunction with the accompanying drawing. DISCLOSURE OF THE INVENTION In one embodiment, the invention includes a module or enclosure, adapted to contain electronic data processing appa atus, transaction processing equipment, and the like, Incorpor ating a flame retardant, impact-resistant, structurally stron 5 relatively light-weight, insulated housing formed of a compo¬ site laminate comprising at least one outer ply, the exterior surface of which reflects radiant energy; at least one .non conductive heat insulating ply of a refractory non-conductive fibrous composition mounted upon the interior surface of said 0 outer ply; at least one structural support element disposed on the interior surface of said insulating ply remote from said outer ply; and a refractory adhesive composition disposed as separate plies between each reflective ply and each ply of refractory ceramic fibrous composition and each refractory ply and structural element. The support element may be one or mor struts, a lattice, a continuous ply, hollow channel, I-beam, combinations thereof and the like. The structural or support element or ply -may also be reflective to radiant heat and, als or alternatively, be electrically conductive. T n one preferred embodiment, there is present on the Interior of said structural element a further refractory cera¬ mic fibrous ply and an Inner (radiant heat) reflective ply disposed upon its opposite surface with a ply of ceramic adhe- • sive interposed between each of the foregoing plies. There may be a plurality of each type of ply -adhering to. one another by means of the foregoing adhesive ply and the succession of reflective and refractory plies can be repeated with inter¬ posing adhesive plies .and repetition of the structural elements as well in the foregoing succession. The outer reflective radiant ply is preferably a metal such as chrome-plated steel. The refractory ply is preferably a ceramic fibrous composition formed of a metal oxide and in significantly preferred embodi¬ ments, an alumina-silica containing composition, a zirconia- containing composition or a zirconia-yttria containing com- position. The adhesive, while non-fibrous, is of the same general chemical composition as the ceramic fibrous ply to which it adheres and is thus like the remainder of each fibrous ply constructed of an electrically non-conductive composition when the plies alternating with the ceramic fibrous plies is an electrical conductor and used or intended for use as such. The fibrous plies, including normally the structural plies or elements which are also preferably electrically con¬ ductive or which, other than the structural ply normally, may be replaced within the laminate by an essentially electrically conductive ply, or one that is primarily conductive. In an embodiment preferred for many purposes there is present at least two internal plies of reflective and electrically con¬ ductive and of a closely meshed screen or continuous layer of copper, for example, and a further internal layer of lead. The several plies are is-olated from one another by electrically and thermally non-conductive fibrous plies. The copper con- ductive plies are connected to a power source and a monitor or alarm system. By way of Illustration, a power source, such as a battery, and alarm are connected in series; the one side of the power source is thus connected in series to one electri¬ cally conductive copper ply and the other side to an alarm, system or monitoring system; the other side of the alarm, in turn, is connected to the second electrically conductive ply so that while the outer protective ply, made preferably of steel, or an enclosure formed of this laminate is not charged the succeeding electrically conductive layers are. As a con- sequence, should one seek unauthorized entry into the enclosure through the outer steel ply, using a drill, the successive electrically conductives piles will, when both are contacted by the drill bit, close the circuit and activate an alarm system. In a less expensive and similarly preferred system the outer electrically conductive ply of steel Is connected to a common ground. A single inner electrically conductive copper ply Is connected in series to a power source and successively a monitoring and alarm ' system which also terminates in a common ground. In one embodiment the interior ply may constitute the structural support ply as- well, in which case it is a con¬ tinuous lamina or at least a close mesh lattice or screen. When the steel outer ply is penetrated by the drill bit, for example, or equivalent electrically conductive tool and con¬ tacts the inner ply closing the circuit between the inner and outer electrically conductive plies of the laminate, the alarm and monitoring system is activated. The security posed by this system will have significant utility where the enclo¬ sure is used as a bank vault. Where an inner reflective ply providing a radio frequency interference barrier made, for example, of a continuous lamina of lead is incorporated in the laminate, significantly enhanced protection is afforded to any documentation or apparatus placed within the enclosure or on the opposite side of the laminate. The system of electrically conductive piles, power source and alarm are" replicated within the laminate and lami- nated enclosure of the invention in other and additional embo¬ diments providing additional assurance that the monitoring and alarm system will work and providing notice of progress achieve in the effort to effect unauthorized entry. The transaction processing enclosure of the invention comprises a vertically disposed housing, celling and base members composed of the foregoing laminate. The housing in¬ cludes a stationary wall; at least one access means to the interior of the transaction processing center or enclosure; and closure means registrable with said access means. Mounted within the base of the center or enclosure, desirably, is at least one turntable, which provides economy of space by per¬ mitting rotation of the data processing apparatus or the like mounted upon'the base for access to all parts of the apparatus through a single access means. Other and alternative means of servicing are also available. Heating, ventilation and air conditioning apparatus and conduits are given, entry to the interior of the booth through both the base and ceiling of the enclosure. To maintain the environment provided within the booth involves minimal energy requirements because of the laminate provided in the housing of the enclosure. Not only is the interior environment resistant or immune from dissi¬ pation through the housing, it is- unaffected by the atmosphere QMH L4 exterior to the housing, as well as being secure against impact, fire and high structural loading; all of the foregoin necessary characteristics to proper containment and mainten¬ ance, illustratively, of electronic data processing equipment -Intumescent flanges are, in a particularly preferred embodiment, mounted along the opposed slideably mounted mar¬ gins or edges of the closure means and are in a further signi ficantly preferred embodiment disposed in spaced relation to equivalent Intumescent flanges mounted upon parallel margins the housing and intumesce to occlude the space between them in the event they are exposed to elevated temperatures.

BEST -MODE FOR CARRYING OUT THE INVENTION Referring now in detail to the accompanying drawing, there are shown in Figs. 1, 2, 3, and 5 particularly, several embodiments of a. composite laminate 10 for use, or used, in modules- or transaction processing enclosures coming ' within the purview of the present invention and shown in Figs 6 to 12. The_ composite laminate 10 includes an outer ply 12 which is formed from a flame retardant composition, a metal most desirably, having a reflective surface and, in a preferred embodiment, impact resistance. This exterior ply is adapted to reflect radiant heat and, at least In that embodiment in which it is the s-ole barrier to material trans¬ fer of radiant heat, is likewise adapted to reflect and serve as a barrier to transmission of electromagnetic radiation, of low, intermediate or high frequency and combinations thereo at low, intermediate and high concentrations thereof. Usually and In one preferred embodiment this ply will be electrically conductive, as well. The one or more recurrent radiant reflective plies exemplified by 12 and 14 of the drawings serve to inhibit the,emination of electromagnetic fields from equipment contained in an. enclosure such as ' that of the present invention employing the laminate-of this invention. Thi serves to protect persons exterior to the enclosure from harm and precludes disruption in the operation of equipment adjacen the enclosure or disposed on the other.side of the laminate. Information developed inside the enclosure or laminate will be protected from analysis and" misappropriation as well. Con¬ versely, the radiant reflective, plies of the laminate preserve electronic data processing equipment, for example, or other sensitive apparatus, from casual or deliberate bombardment by electromagnetic radiation from outside of the panel or enclosure. As will be evident by reference to Fig, 3 and 6 a reflective ply 14 can be and is desirably present as the inner layer of the laminate, as well. The reflective layers may be of the same or different metals. A plurality of recurring reflec¬ tive plies such as 12 and 14 may be employed advantageousl In the laminate on either side of the structural element 15 (and 15a) as seen Illustratively in Figs. 3 and 5. Disposed adjacent the inner surface of the reflective element 12 is a refractory ply 16 composed of a ceramic fibrous material. The several foregoing plies and elements of the laminate are made to adhere to one another by means of a plurality of further refractory plies 17 of a ceramic adhesive, normally and most desirably, inorganic, and of a chemical composition similar to that of the ceramic refractory fibrous adhesive plies that they abut on at least one surface. The adhesive plies are, however, non-fibrous and are deposited on the surfaces that they are to bond together from an aqueous or other dispersion, and then heated. The ceramic fibrous ply and the non-fibrous adhesive piles are composed of metal oxides illustratively, alumina and silica together with reduced amounts of an alkaline oxide. These refractory plies provide a low thermal conductivity and are resistant to degradation at extremely elevated temperatures. At the same time, they provide insulation against extremely low or cryogenic tempera¬ tures or with instrumentation and electronic data processing apparatus requiring these temperatures for effective operation; and will sustain these temperatures within the transaction enclosures. In the preferred embodiments of Figs. 3, and 5 there are at least two ceramic fibrous non-conductive or refractory plies 16 in the composite laminate. As shown further in Fig. 2, the ply 15 is attached to the outer reflective ply 12; and the second Interior fibrous refractory ply 16 adhering ^ to a structural component or ply 15- Both fibrous refractory plies adhere, by means of the adhesive plies 17, as Indicated, to the structural element 15 interposed between the two refrac¬ tory plies 16. A second or interior reflective ply 14 used to Intercept any residue of radiant heat or energy, emanating from a source exterior to the panel and the ' outer reflective ply 12 may be mounted on the second interior refrac- tory ply 18 as shown in Figs. 3 and 4. This interior ply 14 will, of course, also serve to contain any radiant heat and electromagnetic radiation within the enclosure formed by the laminate 10. As indicated elsewhere herein, it is within the contem plation of this Invention to embrace alternating plies of the reflecting and refractory panels in greater number than those shown herein although for the purposes of this invention the total number of each will, for purpose of convenience and economy and the particular application envisioned, extend to about ten of each on each side of a single structural element 15 (of which, however, there may be two or more as well either in recurring sequence or together as in Fig. 3), Additional piles, up to 10 or more may be found desir¬ able for particular applications. As will be evident, essen¬ tial to the practice of the invention is the presence in the laminate 10 of at least a single reflective ply, a single fibrous refractory ply and a single structural element, each o said reflective ply and said structural element being disposed upon opposite .surfaces of said fibrous refractory ply and bonded thereto by an adhesive ply of non-fibrous ceramic refractory material. It is also feasible within the laminate structure provided to Include separate and successive adhering plies of the same or similar composition; for example, succes- • sive metallic piles of the same or different metals, or refrac¬ tory plies of the same or different ceramic fibrous materials. Where the enclosure is intended to resist great stress it is appropriate to include a plurality of structural elements such as the ply (15) and beam (15a) combination shown in Fig. 3, wherein the ply 15 and structural beam 15a are"desirably but optionally made to adhere to one another by means of a ply of ceramic adhesive 17 interposed between the two. Where fibrous refractory plies are mounted upon both sides of the structural element 15 or elements 15 and 15a the structural integrity of the booth is further assured from the enclosure's interior as v/ell as its exterior. This assurance is increased by inclusion in the enclosure housing of an additional reflec¬ tive radiant -ply as well. The presence of this latter ply has the added advantage of providing an Interior surface that may be made of an impact resistant material; a consideration where the enclosure is sufficiently large, as it may be in accordance with the invention, to provide occupancy to one or more persons. The structural elements 15, and 15a where present, are made from structurally strong materials, in one preferred 5 embodiment those resistant to damage from elevated or reduced temperatures or material changes in temperature; and most particularly metals, and illustratively iron, aluminum, steel and magnesium, titanium and nickel alloys. The selection of a thickness and configuration is based .in part on the size of 1 the enclosure and the weight of associated equipment disposed within the enclosure and the other purposes to be served by th structural component as discussed elsewhere herein. The structural elements,, in an embodiment that meets particular objectives of the invention, is most desirably made of a stron 5 but light weight metal of a gauge to ^ permit and enhance the capacity for ready and manual movement and, in thissense the portability of the transaction processing enclosure of the Invention. The structural element may be a ply as described else- 0 where herein, a beam, strut, lattice or other known configura¬ tion. If beams or struts, Illustratively, they can be arrayed horizontally, vertically or at a variety of angles therefrom or integrated in a combination thereof. In any of the fore¬ going forms they ma " also assume a variety of angular or cur- villnear patterns. As shown in Fig. 3 the structural ply 15 and beam or strut 15a occur In combination in a single panel of housing. A preferred outer radiant reflective ply 12 is stainless or chrome plated steel which is impact resistant ° a nd also serves as an electrical conductor t One or two, or more, if desired, immediately Interior succeeding reflective plies 14 separated from each other by electrically non conductive ceramic fibrous plies 6 and from the outer re¬ flective ply 12 In which the several plies 12 and 14 are also electrically conductive constitute a preferred embodiment of the invention and are connected to power sources and alarm and monitoring systems in the manner described, illustratively in Figs. 3, 4, 6 and 8, The " interior 14, and indeed the exterior 12, conductive plies may, if desired, be non- reflective, although, inherently, many electrically conducti laminae are likely to be reflective of radiant heat as well as electromagnetic radiation. Similarly, the structural wall and- beams and the like 15 and 15a are desirably made of a steel, such as a cold rol steel, and while providing strong structural support will al provide an electrically conductive radiant heat and electro magnetic radiation barrier. Each, of the additional properti may be present primarily, exclusively or substantially so, with respect to one another, in the structural support eleme but the element 15 to be significantly useful for this purpo is present as a continuous ply. The electrically conductive ply is most desirably copper, although aluminum, silver and variety of alloys and other metals may be employed for this purpose and including optionally these additional properties for which the reflective ply is utilized in the practice of the present invention, so long as at least one radiant heat reflective ply is present; although at least two are signi¬ ficantly preferred for most purposes. The electrically con¬ ductive interior plies where present, primarily at least, to ' act as electrical conductors, continuous or meshed, may take the form of a fine screen or mesh. Typically, in accordance with the invention, where a mesh or screen Is employed to constitute the Interior condue- tive ply or plies the wire sizes will range from about No. 12 to about No. 48 American Wire Gauge. The lower the gauge, the lower the resistance Incurred. Mesh sizes range usually from about lxl web per square inch to 200.web per square inch, with a preferred range of 50x50. to 150x150. Perforate metal sheets may also be employed.. Copper, aluminum, steel and the like are desirably employed in preparing these mesh or perforate plies as well as thos-e of a continuous uninterrupted character, as described elsewhere herein * These electrically conductive plies are utilized to provide security and alarm mechanisms against physical assault on the " enclosure of the invention through the laminate constituting its wall or through the laminate employed to protect vaults or other structures. With, particular reference to the illustrative embo diment of Fig, 3, therefore, it will be . seen that the reflec tive electrically conductive interior ply 14 continuous and made of copper, is connected to one side of a power source, or for purposes of illustration, a battery 600 which is con¬ nected in series on its opposite side to an alarm or a monit ing or alarm syste -6θ4, which is then connected to the succeeding electrically conductive ply which may also be a copper ply or lamina or an electrically conductive structura layer 15, as shown in Fig. 3, so-that any metallic or elec¬ trically conductive tool or instrument such as a drill bit, or conventional_burglary tool, penetrating the successive,.is lated electrically conductive laminae will activate the alar 604 when the switch.6θ9_ is closed. With, the discharge of th electrical charge between the oppositely polarized plies, th penetrating tool such as a drill or the like may be thermall damaged, and the perpetrator holding the tool will receive a punitive shock, if, for example, the laminate 10 is insulat from th.e ground and the perpetrator is not. In another alternative and preferred embodiment, shown in Fig. 5 and in the enclosure of Fig. 9, (the latter embodiment of Fig, 9_ otherwise discussed in detail hereinaft the electrically conductive, impact—resistant, radiant heat reflective, steel exterior.ply 12 is grounded as shown by th wire element 6θ8. The s-tructural ply 15 of Fig. 9_ is, in tu made of electrically-conductive steel and is resistant to transfer of radiant heat. It is connected to a grounding co ponent or wire 612 in series through an alarm or monitor and alarm system 604 and power source or hattery 600. The alarm system is activated upon introduction of the electrically conductive drill bit or the like through, the outer ply 12 and Into contact with, the interior ply 14 when the switch.609 is in a closed position. Should the enclosure shown in fragmentary section in Fig. 9 be mounted on a platform which is itself grounded and which serves to insulate the enclosure from the ground, and the ground 608 were removed, a voltage power source 600 sufficient to provide potential across- to a ground provided by an unauthorized human agent who has successfully drilled across the laminae 12, 16 and 15 with.,- for example, a metal bit., ' may be provided to produce a current sufficient to be sensed by the human tissue of the agent and may be made suf- ficient to immobilize or otherwise repel him, presuming he i not himself sufficiently insulated. This action ay be taken in the presence or absence of an alarm conponent 6θ4. ' Reference has been made to metals in forming the electrically conductive piles, Metals, in addition to those explicitly disclosed herein but well known to those skilled In the art of electrically conductive materials may, as in¬ dicated elsewhere herein, also be employed for this purpose. Alternatively, or in addition, compositions such as carbon . fiber reinforced epoxy resins and oth.er carbon particle con- tainlng resins may be used to impart electrical conductivity. However, these latter resins are normally significantly less preferred because -of their- tendency to disintegrate and pyrolyze at elevated temperatures, which, the enclosure 200, for example, Is otherwise designed to resist. Interior of the foregoing copper plies 14 of Figs. 3 and 5 Is disposed in another preferred embodiment, a fur¬ ther isolated lamina 14 of.-'zinc to provide a very effective barrier to transmission of electromagnetic waves into or, indeed, from the interior of the enclosure. In the latter instance not only are security interests served but protect¬ ion is provided to workers- who are consistently close to the exterior of the enclosure or laminate which may contain equip¬ ment that emits such waves. The outer ply 12 can, of course, be actively charged If desired, and it is desirable to do so where the enclosure and laminate are used in an environment which is the subject of a high, degree of security and suitable notice is given a limited body of personnel who have access thereto. -2 - The insulated environment provided by the alternat ceramic fibrous plies 16 and the ceramic adhesive plies 17, is such as to permit a current within the electrically con¬ ductive plies sufficient to provide not only an alarm but a 5 punitive or repellent effect, as well, on persons seeking unauthorized entry forcefully through, the laminate or enclo¬ sure wall, as discussed elsewhere herein, A further embodiment of the invention as manifested by the laminate of Fig. 5 illustrates particular advantages 10.. of the laminate and enclosure of the invention. As shown in this Fig. an outer ply 12 is provided of chrome plated steel that incorporates a grounding component shown as a wire 608. The succeeding fibrous ceramic heat refractory layers 16 and ceramic adhesive layers or plies 17 are electrically non- 5 conductive. The first interior ply l4a is electrically con¬ ductive, heat reflective and formed desirably of copper. The ply _,-\_ is_cp . nneeted .in series through.the . alarm_6l2 a switc 609. and power source 610 shown as a battery to a grounding wire 670 so . that when the exterior ply_12 0 interior ply 14a are penetrated, or In the latter Instance contacted, by a conductive element such as a drill bit, the alarm will be activated provided the switch 609. is closed. A second power source and alarm system connected to the electrically conductive plies l4c and l4d also formed prefer- 5 ably of a continuous copper laminate of closely woven mesh is included in the embodiment of Fig. 6. - This second system in¬ cludes, illustratively, a current activating switch, an alarm 6l2 and power source illustrated by the battery 610. connected in series. This second system Independent of the first alarm 0 system serves to provide additional assurance that an alarm will be given in the event of penetration through the plies " l4c and l4d even if penetration of the plies 12 and 14a did not produce a suitable reaction by or to the alarm connected thereto as the result of human error or otherwise. This second system also provides notice of the rate of progress of an interloper seeking forceful entry into, the enclosure to a remote monitor of the alarm system. Indeed, an aural indi¬ cator can be included by modification of the sound of the second alarm, thus more precisely defining the degree of urgency involved to the monitoring security force who are not immediately present at the entry site. The electrical means providing a deterrent and alarm system as described herein are intended to be illustr 5 tive. It will be evident that other circuitry and cooperati deterrent and alarm systems may be devised by those skilled in the art and employed utilizing the laminate provided in accordance with the present invention. The" succeeding reflective ply l4e insulated from 0 the previously described electrically conductive ply l4d by the ceramic fibrous ply 16 and adhesive plies 17, is desir¬ ably formed of zinc or other dense metals effective high energy to form a barrier to electromagnetic radiation inclu¬ ding x-rays, gamma, rays and the like and is designed to pro- tect emissions from penetrating the. enclosure or emanating from the enclosure through, the laminate as the need may exis and as noted elsewhere herein. Succeeding the latter ply l4e in the embodiment of Fig, 6 are alternating ceramic fibrous refractory plies 16, adhesive plies 17, a structural ply 15 and internal heat reflective ply 14 In the manner described, illustratively, with respect to Figs. 1 to 4 and 8, The monitoring of any illicit attempt to secure en through the laminate to an enclosure interior may also, by virtue, of the laminate's structure, be assessed by variatio affected by the attempted penetration " in transmitted voltage, amperage, relative potential, resistance, wave formation and frequency, particularly where alternating current is employed and magnetic field using alternating current. -The Isolated series of reflective plies on the surface and interior of the laminate provide means for moni¬ toring such temperature increases as may occur across the laminate, which with the insulating effect of the laminate, will provide adequate time to react to fire or the like of even the most extreme kind. Thermistors may be attached par¬ ticularly to the reflective, electrically conductive plies for this purpose. -2&- Changes in temperature so measured will report on the attempted intrusion of drills, mechanical cutting instr ments lasers or cutting or welding torches, resulting from the flame or friction imposed on the laminate thereby, 5 Laminate, panel or enclosure penetration or the inception thereof may also be measured by motion transducer such as mercury switch accelerometers and the like attached the exterior and interior plies which through different val at different depths within the laminate indicate whether th 10. vibration is in the environment surrounding the enclosure 2 for example, or in the wall or panel itself. It should be pointed- out, however, that where sen are inserted in varied positions even on a panel 10 or encl sure 200 of the invention, local penetration is possible th 15 does not contact those sensors more or less directly and wi thus avoid activation of an alarm, " whereas_co_nt_inupus_el_ee- trically conductive plies are significantly more difficult evade. It is noted, as elaborated upon hereinafter, that 0 the inclusion of supplemental metallic alloys of high resis tance to penetration by bits, cutting devices and lasers suc as the nickel alloys represented, for example, by the Incone alloys may also be present in isolation between the refracto laminae of the panel 10 or enclosure 200 or 400 of the inven -5 tion but are incorporated only where adequate provision has been made for appropriate electrical " conductivity, thermally and conductive radiant heat absorption and reflection and electromagnetic wave, barriers in accordance with the inventi or where these alloys and the like will also serve one or mo 0 of these primary objectives. The large enclosure 200. of Figs..6, 7, 8 and 9 will, by- way of further illustration, and without limiting t scope of applicant's invention, extend about 7 feet from its base 5 to the supra module partition 274 with an approxima diameter of 5 feet. Elaborating on the laminates in terms specifically- of the enclosure here involved., there is em-- ployed, Illustratively, structural elements 15 of aluminum alloy 30O.3 H 14 ranging in thickness from 1.032 inch to 0.125 inch. ' Stainless steel ranging in gauge from 10 to 2 is also useful in this embodiment and preferred in those instances particularly where strength as contrasted with 5 weight is significant. In contract, a small enclosure 400 as shown in Figs. 11 and 12 will employ, by way of further illustration, an aluminum structural element having a thickness of from ' a.01 inch to 0,125 inch with a preferred range of from 0,020 inch to 0.0.40. inch. The secondary 10 structural element 15a, too, may be of channel, angle, I-beam, or other construction as noted elsewhere herein and vary in thickness- in a preferred embodiment, from 0,032 inch to 0.50 inch with a significantly preferred range of from 0.06 " 3 Inch to 0.125 inch or be composed 15 otherwise of materials such as those described herein characterizing the structural element 15. Where protected particularly by a plurality of reflective plies, the structural element may also be formed of wood, plywood, plastics such as the engineering plastics 20 polyacetal resins*, polycarbonate resins and the like well known to those skilled in the art, or similar material. These latter materials have the advantage of strength and lightness with the very mate-rial disadvantages_in their use, in contrast to a ceramic refractory adhesive such as " 25 described elsewhere herein, reduced by the refractory and reflective laminate. " mounted exterior and interior thereof. Significantly preferred In the practice of the invention Is a cylindrical side-wall housing which can be formed from one or a plurality of, semi-cylindrical panels 30 - such as shown, for example, in Fig. 4 t This- particular conformation has been found to provide significant advan¬ tages to the module including an enhanced capacity to reflect radiant heat and electromagnetic fields-. The reflective ply 12 of plies 12 and 14, by way of illustration, or any repetition thereof in accordance with the invention, is formed of a material having a highly polished surface, adapted, as indicated, to reflect radiant heat and electromagnetic radiation as indicated elsewhere herein. Suitable metals for use in the practice of the inven tion, are by way of further illustration and not of limitatio polished steel, a steel and copper or aluminum ply, aluminum, aluminum alloys, titanium alloys, cadmium alloys and chrome plated metals such as steel, chrome nickel steel, chrome man¬ ganese steel, chrome steel and stainless steels. Specific • illustrative steels useful for the purposes herein described are types ASTM 4l0,,4l4, 420 and 430. Particularly preferred is a chrome-plated steel having a low total emissivlty within the range of from 0.02 to 0.2 at 25°C. (as characterized in the Handbook of Chemistry and Physics, 50th Ed. 1969-1970. The Chemical Rubber Co., Cleveland, Ohio, p. 4-90). It is also- within the scope of this invention to include an exterior covering upon the outer most ply to render the panel esthetically acceptable in interior or office environments as well as to provide corrosion resistant finishes in exter¬ ior environments. Therefore, this surface may be treated or primed and finished with paint or even treated with decorative coverings such as vinyl tiles or films and the like without influencing the utility of the invention. As the reflective plies 12 ( " and 14 where present, and such additional plies thereof present) are, characteris¬ tically, excellent conductors of thermal energy, the panels 10, where not formed to provide a unitary housing for the transaction processing enclosure are brought into direct abutment by welding, or other standard means for providing an integral unit, so that heat from a source of thermal 5 energy or an electromagnetic field applied to a selected portion of the panel or housing surface will be rapidly dis¬ sipated over the entire area provided by said panel and any adjacent panels forming the walls, ceiling and base of the transaction processing enclosure. In bringing the reflectiv ° plies into abutting relation, the refractory layers " Of conti¬ guous panels are brought Into contact as well, and may be made to adhere to one another by means of a ceramic refrac¬ tory adhesive. A lamina formed of a metal such as the foregoing for US e herein will be, in a particularly preferred embodiment, • from 18 to 28 gauge ( " 0.0149 inch to 0.0478 Inch respectively) in thickness, and most desirably of about 24 gauge. Greater thicknesses, for example, up to 0.375 inch and more are oper¬ ative, and, indeed, are preferred, for some purposes, as where security against vandals and physical attack is involve The individual laminae of reflective piles such as 12 and 14, for example, are, in one embodiment., and indeed in a variety of embodiments, desirably formed of different metals as indicated elsewhere herein, for example, where employed In the enclosure 200 and 400, the outer lamina or ply 12 when made of polished steel is generally invulnerable to physical impact and is, for example,-"bullet-proo , while providing a barrier against low frequency electromagnetic fields; while an inner ply is made of aluminum or copper that is substan- ° tially impervious to transmission of high radio frequency energy and is electrically conductive for monitoring, alarm and like purposes as discussed hereinabove. The object, or at least one object, served by this combination is the pro¬ tection of any information stored or being used in the trans- action processing enclosure such, for example, as magnetic tapes, disks, solid state elements or "chips" and capacitor memories from damage, deliberate or inadvertent, effected by radio frequency energy of 1ov; and even very nign concentra¬ tions including background radiation. The reflective plies such as 12 (and 14, where present) are intended particularly where disposed externally and internally to the structural element 15 , to provide pro¬ tection from both radiant thermal energy and possible fire damage and to contain and limit any fire " occurring in the transaction processing enclosure to the unit as well as pre¬ venting penetration of fire or undesired temperature changes from the exterior either directly or as a result of undermin ing the " structural integrity of the booth. The concern here is particularly significant since fires occurring in connec¬ tion with electrical and electronics equipment tend to be particularly persistent and damaging. Other metals or alloys thereof such as lead or anti¬ mony or tellurium alloys thereof may be incorporated addition ally as noted elsewhere herein where concern is had with sele tively adverse conditions such as X-rays and gamma rays to which contained equipment of the transaction processing cente may be particularly vulnerable. The thickness and continuity of the lead ply, the use of a mesh or retlculum- depends on the degree of protection desired for a particular application such, for example, as may occur in nuclear facilities and the like. The refractory plies of the composite laminate 10 are formed of metal oxide fibers characterized by their great refractory capacity, low thermal conductivity, and resistance to chemical attack. The fibers often and desirably include stabilizers that permit the insulation to continue to be ef- fective above the melting point of at least certain of the insulating metal oxide fibers that could not otherwise be used to advantage. The fibers for use in the refractory plies of the panels and housings 10 of the invention are those incorpora-. ting, as at least a significant or major portion by weight, oxides of one or more metals, beryllium, hafnium, magnesium, calcium, strontium, barium, scandium, silicon, yttrium, an anum, ces um, an um, z rcon um, vanadium, πiouiuiu, tantalum, chromium, molybdenum, tungsten, manganese, iron, cobalt, nickel, copper, zinc, lead, thorium, and the like. Illustrative of the foregoing oxides are BeO, gO, CaO, SrO, BaO, S10-, γ 2°3 * L a0 2 , Ti0 2 , Zr0 2 , V °3 > Na 2°3 a 2°3> Cr0 2> Si0 2 , Hf0 2 , o0 2 , W0 2 , Fe0 2 , Co 2 0 3 , Ni 2 0 2 , CuO, ZnO, CdO, and Al O - Other oxides that may be present in combination with one or more of the foregoing oxides, are illustratively herein have a mean average fiber length of from as little as about 1/16 inch to about 3 inche or more in length and an average fiber thickness of from abo 3 microns to about 10 microns or more. Preferred are those fibers having mean average fiber lengths- of from 1/4 to 3 inches, with an average diameter of from 3 to 10 microns and most desirably 2 to 6 microns. These ceramic fibers are wel known to those skilled in the art to which this Invention pertains and are prepared generally by the following illustr tive procedures, the first of which, by way of illustration, involved impregnating a preformed organic polymeric material, such as cellulose, rayon, silk and the like, with one or more salts or hydrolysis products of salts of metal elements that form the metal oxides referred to hereinabove; heating the impregnated organic material under conditions effective in • preventing ignition and in the presence of an atmosphere including an oxidizing gas at a temperature sufficient to pyrolyze the organic material. The resulting carbon is removed as a carbon-containing gas and the metal or metals present are oxidized.,to their respective metal oxides. The metal oxide fiber has a configuration similar to that of the original polymeric material. This method is adapted parti¬ cularly to the production of zirconium oxide fibers. In another preferred embodiment, the metal oxide and other com¬ ponents are mixed thoroughly in an arc furnace until a bath of molten material is formed. The furnace is then tiled to allow the molten material to pour from the furnace in the form of a small stream which is stuck at substantially right angles by a stream of compressed air. The siream oi inv± -e-n material is dissipated in the form of fine fibrous material which is collected upon a mesh screen or revolving drum posi¬ tioned several feet in front of and downstream from the fur- nace. This process is adapted particularly for use in the preparation of aluminum oxide fibers. In addition to the desired fibers, a portion of the product assumes the shape of pellets. These pellets, often referred to as "shot", are substantially removed " in the collec tion of the fibers as described hereinabove. The elimination of this pellet sized material increases the refractory quality of the fibrous material formed. - Preferred fibers are those made from aluminum oxide and zirconium oxide. A particularly preferred aluminum oxide fiber for use in the practice of the invetion that will retain its integrity as a refractory material at elevated temperatures is that formed by melting and fiberising mixtures of aluminua (A1 2 0_) and silica (SiO ,- wherein aluminum oxide is present by weight of alumina and silica content within the range of about 40 per cent to about 95 percent and preferably about 51-7 percent to about 92.8 percent, and silica is present in an amount of from about 60 percent to about 5 percent, and preferably, abou 48.3 percent to about 7.2 percent respectively. There are present, as well, incorporated normally in the alumina employed, additional trace"amounts of--SI0 2 and an alkali metal oxide; the former In percentages normally of up to 0.03 percent or more; and the latter, ususally as Na-0, and less frequently as- K ? 0, in amount- of up to about 1.0 per- cent by weight. Iron oxides, particularly Fe^O-^ In amounts usually of up to about .03 percent and titanium oxide in an amount of up to about .005 percent, with water, free and combined of up to 2 percent, may and usually are present, as well. The foregoing references to percentates and to percen- tages by weight of the alumina in which the components recited are contained. Up to about 7.5 percent o-f- the silica incor¬ porated in the refractory composition of the invention may be substituted by zirconla in one series of embodiments. Of course, zirconia can substantially replace t e a umina m an alternative embodiment as discussed more fully elsewhere herein. A significantly preferred alumino-silicate formulati 5 for use herein sold by Alcoa as tabular alumina under the trade designation, T-6l, incorporates the following component in the percentages by weight indicated: Al 0 -99-5$ and more; SI0 2 -.025-, Na 2 0-.02J6; Fe 2 0 3 -.03£ T10 2 -.005£. An alternative alumina source also preferred, and less expensive, and also 10 sold by Alcoa as A-1 grade white alumina contains the followi components In the following percentages: Al 2 0_-98.89$ Si0 2 - .03#; Na 2 0 (combined) -.50£; H^O- (free) -1.25S. - Particularly preferred for use in the practice of the present invention are refractory compositions having good 15 insulating properties and,illustratively, a low capacitance, low dieletric constant, and a small power factor. A preferred refractory material is one having a dielectric constant of fro about 5000 volts per millimeter of thickness (v/mm) to about 50v/mm, arid more desirably 250v/mm to 50v/mm. . An alumino- 20 silicate refractory composition containing . 6% SI0 2 , 0.3 a 2 0, 0.15? B 2°3 3 and ° - 02 % Fe 2 0 ? ce inorganic components having a dielectric strength or constant of 70 v/mm Is further illustrative of a preferred insulating material for use In the refractory ply of the invention. This 25 particular composition manifests a dielectric constant or strength of 70 v/mm when tested in air ' according to ASTM D 149 (Short Time Test 7.1.1) using 2 Inch diameter, 1 inch thick brass electrodes, with edges rounded to a 0.25 inch radius, with a voltage rise rate of 500 v/sie. _ ' . . ■ _ Afu inosilicates / fibrous paper compositions for use herein and coming within the characterization provided herein- above are marketed commercially under the trademark FIBERPRAX, by the Carborendum -Company, Niagara Falls, New York. The dielectric strength of the aluminosilicates is 5 increased by reduction in the level of impurities which are usually present as water, iron and other'metals, and an improved density. A density within the range of about 10 pounds per cubic foot (pcf) to about 125, pcf a d higher is known, by way of illustration, to provide effective insulating compositions for use in the refractory plies of the invention. The silica sources most conveniently employed are flint and white sand. Preferred aluminum oxide fibers of the foregoing character are thus prepared illustratively as follows: A batch of A-1 grade white alumina ore (Alcoa) in an amount of 50 parts by weight; flint, 50 parts by weight;, and 1.5 parts by weight of borax (Na 2 B^0--) are mixed thoroughly and fused in an arc furnace of the type commonly used for making alumina abrasive materials until a. substantial bath of molten material of obtained. The furnace is tilted and the molten mixture is poured from the furnace in the form of a small stream Impinging on the stream from a right angle. A stream of compressed air under 80 pounds per square inch pressure can be substituted for the same jet. The stream of molten material is transformed into a mixture predominantly of pellets or "shot" and the desired fibers that are then collected upon one-quarter inch mesh screen placed in frontof, and about 5 feet removed from, the furnace. The shot is removed substan¬ tially. . The resulting fibers or fibrous glass manifest the following composition: Al 2 0 2 -5 .- : 7?; Si0 2 - 5-77$; B 2 0 -1.06?, and Na 2 0-050#. Other illustrative and preferred refractory fibrous aluminum oxide products for use in the present Inven¬ tion Include fibers composed of Al 2 0 g -50?; Si0 2 -ab ut 50 % ; with trace amounts of Na 2 0, B 2 0, and Fe 2 0 3 ; and, specifically, 51-7? A1 2 0 3 , Hj . 6% S10 2 , 0.3? Na 2 0, 0.15?B 2 0>. and 0.02? Fe 2 0-,. The foregoing, fibers can be used in effective refrac- tory plies herein at continuously maintained temperatures as high as 1290°C. A preferred range in density for the foregoing alumina fibers are within the range of 0.12 grams per cubic centimeter (g/cc) to 0.25 gcc. The thermal conductivity of the preferred alumina fibers is within the range of 0.5 Btu/hr. ft. 2 °F. x 10 ~3 at 400°F. to 0.7 Btu/hr. ft. 2 °F. x 10 ~3 at 1200°F. As indicated, other particularly useful ceramic refractory materials are derived from zirconium oxide-containin fibers. These compounds are prepared advantageously using the relic process in which organic polymeric materials are employed 5 as described generally elsewhere herein. These latter fibers are prepared by impregnating an organic polymeric material characterized by a structure of extremely small crystallites held together by a matrix of amorphous regions that enlarge and admit the metal compounds 1 on immersion in a suitable solvent. These include, illus¬ tratively, cellulosic materials such as rayon, saponified cellulose acetate, cotton, wool, and remie; protein materials such as silk or wool; and polyesters, acrylic polymers, poly- vinyl chloride, polyvinyl acetate and the like, and polyester --5 urethanes and polyether urethanes. Particularly preferred Is rayon because of its structural uniformity, good imbibition,- and low impurity content. The rayon is caused to Imbibe 0.25 mole, and prefer¬ ably 1.0 mole, to 2 moles of zirconyl chloride for ' each glyco- 0 sidic unit or mole of the cellulose chain. Other zirconium compounds such as zirconium acetate, zirconium oxalate and zirconium citrate may also be used. While zirconia has a fusion point of 26 " 77°C and is. thus an excellent refractory material, zirconia undergoes a phase change from the mono- 5 clinic to the tetragonal form at about 1000?C. Zirconia is however readily stabilized by heating in admixture with one or more Group III B metal compounds. The zirconia is conven¬ iently stabilized however by firing it to 1700° C or higher with 11.5 to 15 weight percent yttria to produce the cubic form or by firing at similar temperatures with 8-15 wt. % magnesia, 6-15 wt.? calcia, silica, scandia, and oxides of the rare earth metals such as lanthanlde metal oxides. Dis¬ cussions of- other known methods for stabilizing zirconia can be found in Ryschkewitz, Eugene, Oxide Ce " ramics, pp. 364-367 Academic Press, New York (I960); Campbell, I.E., High Tempera¬ ture Technology, pp. 77-81, John Wiley & ^ Sons, Inc. New York, New York, incorporated by reference herein. With non-celluloslc aterlals, the degree of imbibition extends ' from at least 0.1, and preferably 0.5, to 1.0 gram equivalent metal ion in the metal compound Imbibing solution per gram of organic material. Imbibing of the zirionyl chloride is effected using a water medium at a temperature of from 50°C to 65°C to shorten the period of immersion. Excess moisture is removed by blotting of the fibers with absorbent paper, high velocity gas streams, vacuum filtration or centrifugatlon. The fibers are then dried and heated to a temperature of between about 400°C and about 800°C at a rate between 10°C per hour and 100°C per hour ' in an atmosphere containing from 5 to 25 " volume per cent oxygen and thereafter maintaining the fibers at a temperature of 400°C to 800°C in an oxygen-containing atmos¬ phere until all of the original organic fibers have been reduced to carbon and volatilized and substantially all of the zirconium present has been oxidized to zirconium oxide. The foregoing process- permits a range of process variables in addition to those described and directed particularly to avoid¬ ance of ignition and burning of the organic portion of the Impregnated organic material. The process can be modified, as well, to provide a continuous process. Other variations in -permissible reaction conditions are illustrated by the following three methods, wherein, in all instances, the cellulosic fibers are immersed, as described above, in an aqueous solution of zirconyl chloride, excess solution removed from the impregnated fibers and .the fibers dried. In the first illustrative method the carbonization- oxidation step is car-ried out by heating the fibers in air at a uniform rate from room temperature up to 400°C. over a 24-hour period. The fibers are then heated in air at tempera¬ tures between 400°C. and 600°C. , preferably closer to 600°C. S for an additional period of up to twenty—four hours. This procedure is illustrative of ignition control by slo"tf oxidation over a long period of time. OMPI In the second method the carbomzatioπ-o idatiOfv step is carried out by heating the impregnated fibers, in an argon atmosphere from room temperature to temperatures betwe 600°C. and 1000°C. In less than one hour. The oxidation is then carried out by maintaining the fibers at about 800°C. in an atmosphere of argon, containing at least 5 volume perce water vapor for a period of one to ten hours. This procedur is illustrative of ignition control by rapid pyrolysis in a non-reactive atmosphere followed by rapid high temperature oxidation using oxidizing agents of relatively low reactivit In the third method the impregnated fibers are rapid heated, often in " .less- than five minutes, to about 400°C. in an atmosphere containing less than approximately 10 volume percent oxygen. The oxygen partial pressure is then graduall increased at constant temperature until the carbonaceous material from the cellulose and the metal compound have been oxidized, generally in a period of 1/2 to 3 hours. This pro¬ cedure avoids ignition by direct control of the oxygen partia pressure in the environment of the fiber. Hydrolysis of the zirc ' onyl chloride is also used to effect imbibition of the metal, into the organic polymeric material in an alternate embodiment. The foregoing metal oxide fibers when used in the laminae of the invention can be formed for this purpose into board, paper, felt, batting and fabric forms well known to those skilled in the art and including random distribution of the fibers. The term "fabric" is intended to embrace com¬ positions wherein the -fibers have been interlocked, including woven, knitted or brai ed articles, for example, including certain felts wherein the individual fibers are interlocked by needle punching, after felting. Preparation of fibers such as the foregoing and fabrics employing these fibers are • described in U.S. patent 2,557,834; U.S. patent 3,406,025; U.S. patent 3,663,182; and U.S. patent 3,385,9.15- Ceramic fibers formed primarily of zirconium oxide, and rendered stable to temperatures of 1000°C and above are described in U.S. patent 3,663,182 and U.S. patent 3,860,529 and the fibers of U.S. patent 3,Sol, 47 reciting additional " means "" for rendering zirconia πoers raurc thermally resistant by coating thereof with silica are also useful in the fibrous refractory plies such as 16 and 18 " employed in the practice of the invention. The foregoing patents are incorporated by reference herein. whether characterized as felts, fabric, boards, paper or the like, the refractory plies employed herein composed of plies of ceramic fibers and whether of alumina and silica or zirconia or, indeed, hafnium oxide or yttria, will retain their integrity and will provide effective resistance and low thermal conductivity to temperatures exterior to or presen in the interior of the transaction processing center for ex¬ tended periods of time; even up to 2200°C. in many cases. This is particularly significant because the reflective layers such as 12 and 14 and the structural -elements or plies 15 and 15a will often be unable to survive these temperatures. For this reason it is particularly desirable " to provide refractory plies that are rigid, a property that is readily infused into each of the fibrous plies by methods well known in the art and in a manner such as described hereinafter. The fibrous refractory ply 16 will, by way of illus¬ tration, in the event fire and heat have destroyed the outer metallic reflective ply 12, preserve the Integrity, under rigorous conditions for extended periods of time, of the structural elements 15 and 15a which are isolated from the ambient atmosphere external to the enclosure 200 " (such as shown In Figs. 5 to 8 hereof') or 300 (seen in Figs. 9 and 10) even with the removal of the outer ply 12. The structural elements 1*5 (and 15a) are " similarly protected from an elec- trical fire or the like In the enclosure's Interior by one or more refractory panels 16. The reflective ply 14 will, of course, be preserved for a period of time, where the fire is external to the enclosure 200 and will continue to retain its structure and its ability to insulate its housed data processing equipment or thelike from the adverse environment without. The same Is also true with respect to the external reflective ply 12 x-:here a fire or other dramatic escalation of the temperature occurs inside the enclosure 200. . The refractory plieε 1 .'2nd any replicati n thereof that may occur, have thicknesses of from about 1/32 to about 3 inches, and more desirably 1/16 to 2 inches for most purposes and preferably from l/l6 inch to 1/8 inch. The assemblies of fibers whether felts, batting, fabrics or the like v/hen compacted to the foregoing thicknesses, mani¬ fest an enhanced reduced thermal conductivity. It is particularly advantageous for application in the practice of the present invention to form plies 16 of the panel or housing 10 in the form of one or more layers of metal oxide fibrous paper, each layer having a thickness of from 5 to 30 mils. Where, as- significantly preferred, a plurality of layers of papers are employed to form any single ply,- 16 for example, .the..fibers, will .manifest desirably.. a substantially parallel orientation,In any single layer and will be similarly oriented but perpendicular thereto in. the succeeding layer to enhance the strength of the resulting ply 16 and the resulting panel 10.. a thin coat of cer-- amic refractory adhesive may be used between these layers of paper. This increased strength is particularly effective where the ply 16 is rigidized, as described -hereina er, The presence of a plurality of layers of ceramic fiber in the refractory ply will enhance the resillancy of the ply and panel 10 where the ply components are not rigidized. This feature is employed in a particularly advantageous manner to improve the impact resistance of the panel 10. Thus, .where concern exists for a possible explosion on, or adjacent to, the exterior reflective ply 12, the outer fibrous refractive ply 16, is resiliant and non-rigidized, will better absorb and dissipate without fracture the effect of detonation. The second or subsequent Interior fibrous- refractory plies 1-5 may be rigidized, desirably, as the risk of fracture is reduced, thus absorbing and reflecting the residual Impact of explosion while adding to the structural strength-of the panel 10 and thus limiting its ability to penetrate the enclosure 200. Where several layers of ceramic fibrous paper are employed, in forming a refractory ply their individual thicknesses are normally within the range of about 0.012 Inch - - - - - - - . _ij 0 _ to about 0.125 inch at 0 psi pressure and about 0,095 inch at 8 psi pressure. Thicknesses of up to 0.25 inch at 0 psi pressure are also operative. In any case, a plurality of alternating reflective 5 and refractory plies exterior to- the structural element 14 are normally preferred. The first fibrous refractory ply may then be flexible, for example, where two such plies are disposed exterior to the structural element, and the second, rigidized to protect this latter element from fractu 10. and, as a consequence, the Integrity of the enclosure. For particular applications the election of which plies should be rigidized can be reversed as, for example, where the explosion is viewed as more likely to emanate from the enclosure's Interior in which the effect of this reversal 5 will be to aid in containment of the explosion. As the various plies of the panel or- a plurality of these panels forming the enclosure 200 or 400 are continuous so is the structural element or ply 15. Accordingly, the element 15 Is Isolated from the exterior environment by at least a single 0 radiant reflective ply 12 and a single ceramic refractory ply 16, as well as the refractory adhesive plies 17- Conse- . quently, where extremely high temperatures to transmit heat ., ' through the exterior plies 12 and 16 to the element 15, this latter component, formed usually of a good conductive material 5 will dissipate this residual heat throughout the entire elemen 15 of the enclosure 200 or 400. In this event, however, it is particularly desirable to have at least one fibrous refractory ply 16-as well as the additional refractory adhe¬ sive piles 17 disposed Internally of the structural element 0 15 to insulate the interior of the transaction processing enclosure 200 or 400 and its contained apparatus from the heat of the structural element. It will be evident too that the composition of succes sive refractory piles and particularly those on opposite sides of the structural element may vary in thickness, composition and physical .properties- such as density,_as described elsewhere herein, and consistency within the parameters defined herein. - l- r. As indicated heretofore, the several elements of th composite laminate of the invention adhere to one another by means of the adhesive plies 17 employing a ceramic adhe¬ sive. Significantly preferred are the metal oxide-containin refractory adhesives. These latter adhesives may also be applied as well to bonding and rigidizing of the fibers of ea refractory ply. Among the inorganic refractory adhesives for use in the practice of the invention that remain effective at ele vated temperatures fof-. 126 " 0°C and significantly above, are colloidal silica, colloidal zirconia and colloidal alumina. These adhesives have particular application with aluminum silicate fibers characterized hereinabove wherein the fibers have an alumina content of from about 45 to 95 percent. The foregoing inorganic oxides employed as adhesives i.e. colloidal silica, colloidal zirconia and colloidal alumina, are employed as aqueous dispersions, preferably in a range of 1 percent to 30 percent of oxide by weight of the total dispersion. In a preferred embodiment these colloidal adhesives are prepared including ceramic fibers e.g. those containing 51.7% A1 2 0 3 , 47.6# SI0 2 , 0.3S Na 2 0, 0.15$ B 2 0 3 and 0.02£ Fe 2 0 3 (as described elsewhere herein in context with the refractory fibrous papers us-ed In the refractory plies them- selves) or small amounts of zirconia in the order of less than 1%, that are reduced In length by grinding, for example, in a ball mill, until the fibers have a length to diameter ratio predominantly iri the range of from about 10:1 to" about 50:1. The milled fibers are mixed with an aqueous dispersion of the foregoing oxide, sufficient oxide being used to pro¬ vide an oxide content of from 3 percent to about 40 percent by weight of the mixture on a dry basis-. The mixture is then applied to a ply of the larger ceramic refractory fibers des¬ cribed- hereinabove in which the mixture may be utilized as a binder and as a surface coating to cause the ply to adhere to successive coats thereof and ultimately and in any event - 2- ~~ ' " to Dond the refractory ply or- plies to the radiant reflective layers and structural elements of the composite upon curing thereof. • Curing is effected by heating of the laminate, or portions thereof to which the adhesive has been applied, in an oven at a temperature of about 2Q0°F. Curing can also be effected desirably over longer periods of time at room temperature. Rapid curing, at temperatures up to about 2000°F will result in porous structures, and may be undertaken where porosity is not a concern. The foregoing adhesive includes about 3 percent to about 0 percent of metal oxide derived from the colloidal oxide on a dry weight basis and milled aluminosilicate fibers. A preferred proportion of colloidal oxide, for example, silica is about 10 percent to about 15 percent and most desirably about 10 percent. Other desirable adhesives ' in the practice of the inve tion for bonding of ceramic fibrous plies of alumina silica to one another and particularly to the reflective radiant piles and structural elements of the invention are zirconla-containi adhesives containing at least" 85 weight percent zirconium oxid and preferably from 1 percent to 5 "percent by weight of silico oxide. Particularly- preferred, where the composite laminate 10 of the Invention is to be exposed to elevated temperatures are compositions such as the foregoing Including up to 10 weig percent of ttrla. Yttrla stabilizes the zirconia- against decomposition up to about 40.00°F. An illustrative zirconla-containing adhesive composi¬ tion for use herein is~ one containing by weight 86$ ZrO S 8.8$ Ϊ2 0 5 3- $ Si0 2 ; 1.2 -K 2 0 and Na 2 Q and other trace inorganic components in an amount of 0.3$. As in those Instances where a colloidal metal oxide is employed, drying and curing occurs at room temperature over a period varying from a few minutes to a day or more depending ' " inte ' alia on the humidity, tem- perature, and amount and size of the article Involved. Drying and curing are readily accelerated, where--desired, by heating of the composite laminate incorporating the adhesive at up to about 200°F. The curing step is also completed desirably by heating to a temperature of 800°F. Where the final curing step is completed at this latter temperature the laminate is more stable to wet or humid conditions and all volatile com¬ ponents are eliminated prior to use. A significantly pre- ferred refractory adhesive is a mixture of the following components (percent composition of cured adhesive): 46.5$ Si0 45-4$ 1 2 0 3 , 1.6$ e 2 0 3 , 2$ TI0 2 , 0.2$ CaO, 0.1$ MgO, and 4.2 Na 2 0 or K 2 0 (or a combination thereof). The uncured form of this adhesive is characteristically composed of twenty to forty percent aqueous solvent. Variations in the amount of solvent varies the consistency of the adhesive composition. In general, trowel or brush type-methods of application are used to facilitate the application -of the thin layers of this significantly preferred refractory adhesive to the various layers of elements of the panel 10. -.Spray application is also feasible upon addition of solvents. The foregoing refractory adhesives and particularly those indicated to be preferred or particulary preferred may be utilized to bond a variety of metals including aluminum and its alloys; steel .and Its alloys, and titanium and its alloys to the ceramic refractory plies such as 16 in paper, felt, or fabric form, as well as to bond the layers of said preferred ceramic refractory material to each other when a plurality of said layers are employed to form said refractory element Iβ. The adhesive is preferably applied In a "" thickness of 0.02 inch to 0.625 inch, .forming the refractory bonding plies or layers 17 between the refractory layers 16 on the one hand and he structural element 20 or elements 15 and 15a, and the plies 12 and 1 on the other hand, as shown in Figs. 2, 3, 4 and 5. The preferred refractory adhesives are equally effective whether the preferred fibrous refractory ceramic plies are pliant or rigid. The plies 16 are rendered stiff or rigid by incorporation among the fibers of a solution of the same composition as that of the fibers-, that is, with respect to zirconia fibers, zirconia, free of additives such -h - ' ' ' as silicates and phosphates, but including, desirably, yttria and silica as characterized elsewhere herein. The rigid Inducing solution or rigidizer is applied to both sides of each of the plies 16 prior to assembly of the panel 10. Excess amounts are removed from the fibers in their assembled state by a roller, squeezer or the like. The rigidizer is similar or Identical with respect to its non-aqueous components in composition to the foregoing adhesives and fibers, but is used in a more dilute aqueous state, i.e. 3 to 6 centipoises and preferably about 4 centi- poises, sufficient to permit penetration of the fibers of the paper, board, felt or the like of the refractory fibrous ply. It thus serves alike as an adhesive; differing only in con¬ sistency in order' to effect the preparation of the panel or enclosure 10 In the most efficient time span. In applying the rigidizer and adhesive, in any event, arid after the excess adhesive is removed, the treated ply is dried with a stream of dry air or in an oven at "low temperature until the rigld- izing composition becomes tacky at which point the ply is attached to the reflecting ply 12 or 14 and the structural element 15 or 15a. The laminated composite 10 is then dried further commencing at about 100°F for 3 to 4 or more hours, increasing the temperature to 24θ°F to 300°F for a further period of 3 to 4 hours. If there are one or two refractory layers- in the composite 10 the foregoing drying and partial cure is completed in 1 to 2 hours. If a number of " additional layers within the scope defined hereinabove is used effective drying requires up to 24 hours. Curing is completed by heating to a temperature of 80Cf°F to 1000°F for a period of one hour and up to 2000°F desirably in accordance with the invention to impart increased strength thereto. When cured the preferred refractory adhesives and bonded panels or plies are resistant to high and low frequency vibration as well as moisture or humidity and are stable when subject to temperatures exceeding l850°F and, indeed, in excess of, 2000°F and up to 3200°F, for a ' peribd of at least- two hours at ambient pressure. When the preferred refractory silica-containing adhesive is employed, it has been discovered that gentle, uniform compression at a pressure of 1 to 10 pounds per square inch on the panel for periods from one to seven hours at 25°C to 500°C temperature and 10$ to 50$ relative humidity are normally sufficient to produce a uniform, laminated panel 10 with a cured adhesive system therein. For an illustrative two foot square panel comprising refractory elements consisti of two 1/8 inch thick sheets of said preferred ceramic refrac tory material, and in which the reflective and structural elements are 24, and ' l4 or 18 gauge steel, respectively, two hours of curing time is adequate.- Adhesives, other than the foregoing inorganic metal oxide refractory adhesives can be employed in the practice of the invention; but have severely limited circumstances where they can. be employed, and are con¬ sequently, significantly less preferred. These adhesives are organic compounds and will, for example, degrade at relatively reduced temperatures thus tending to defeat the purpose and the objectives the practice of the invention is designed to achieve. Illustrative of these adhesives are nylon-epoxy, nitrile-epoxy, epoxy phenols, epoxy ' elastomers, polyamides, polybenzimidazoles, other condensed ring linear polymers, polyurethanes, epoxy resins and the like. These organic ad¬ hesives may, of course, be used more readily with the interior plies as, for example, those used for bonding the structural element, where they will be protected. The inorganic refractory adhesives are, as indicated elsewhere, herein, significantly preferred for bonding the elec¬ trically cnductive anσ^charged laminae into the laminate struc- ture, because- of their low electrical conductivity. These adhesives also have extended curing times resulting from their aqueous solvent components incorporated therein. The electrical conductivity of the organic adhesives is significantly higher, although the electrical conductivity of the epoxy resins is less so that that of the polyurethane and polyamide adhesives. When the refractory elements or plies 16 are composed of refractory ceramic materials containing higher concentrations of Al O,, as described elsewhere herein, use of an adhesive with an increased relative A1 2 0^ content and a decrease of the Si0 2 content according generally with the relative content thereof in the contiguous fibrous refractory ply has been found to be desirable. The use of refractory ceramic materials with high alumina content is desirable wherein exposure, or likelihood of exposure, to- temperatures up to as high as 1500°C may occur Where fibrous Zr0 2 , Hf0 2 and Y 2 °-, containing ceramic compositions are used to form the refractory piles 16 and 18 a refractory adhesive composition having similar oxide content is required. Most desirable of these adhesives are those containing 80$ to 90$ Zr0 2 , 5$ to 10$ Y 2 °3 - 1J to 5 ^ SI0 2 , and 1$ to 2$ Na 2 0 and/or K 2 0 dry weight. Use of an aqueous solvent comprising 20$ to 40$ of the wet or uncured weight of the adhesive is sufficient to provide an adhesive consistency ranging from that brushable or sprayable to that requiring trowel type application. The adhesive plies 17 In the panel 10 may be cured by exposure to temperatures ranging from 400°C to 500°C while the panel is subjected to uniform pressures ranging from one to ten pounds per square inch, for periods ranging from one to several hours, varying directly with the size of the panel 10. The panel thereby formed is capable of withstanding prolonged exposure to temperatures as high as 2200°C, although the outer reflec¬ tive elements or pile may be destroyed or damaged after brief exposure to this temperature. Illustrative adhesives, as well as ceramic fibrous products to be integrated therewith, for use in the practice of the present invention are those described in U.S. -patent ^ 3,077,412; U.S. patent 3,736,160; and U.S. patent 3,232,401 and Incorporated by reference herein. Tt is- desirable, in accordance with the invention, to Insure that the isolation of the reflective plies 12 and 14 and the structural element or elements 15 and 15a are sustained - .. .at the outer margins 22 of the panel 10 where joining of adjacent panels does not occur. While, the margins of a pane need not be further modified to provide an at least minimally operative enclosure, it is preferred where an access means to the interior of the enclosure 200 and " 300 is defined, to provide a ply of ceramic fibrous refractory material 24 as a trim or molding. This molding 24 may be pliant or rigid and made to adhere to the margins " of the plies by adhesive such as described hereinabove. A plurality of panels 10 may be fused along their margins so that the radiant and reflective plies and struc- . tural elements of each panel are continuous with one another, interrupted only by the refractory adhesive used to secure their structural continuity or the " use of tongue-in-groove edges for friction fitting or other means well-known to those skilled in the art. Fibrous ceramic' ngles 28 (Fig. 3) or strips 30 (Fig. 2) may be used as well to furnish the integra¬ tion necessary. The moldings 24, angles 28 and strips 30 may also be formed of intumescent material or where they are dis- posed on a reflective layer they may Indeed be metallic. The use of abrasive materials that prevent-,- or inhibit significantly, the passage of the tools used conven¬ tionally in piercing the walls of safes and the like to abet unlawful or unauthorized forceful entry is thus also contem- plated by the present Invention. The penetration resistant abrasive compositions for use herein include carbides, such as silicon carbide, corresponding to -the mineral moissanite, having.a hardness of about 9-5 (Mohs scale) or 2,000 (Knoop) and a specific gravity of 3.2 and sold, illustratively, under the trade names, Carborundum, Carbolon, and Crystoton; boron - carbide, having a hardness of about 9.32 (Mohs scale) or about 2800 (Knoop); as well as boron nitride, available as an abra¬ sive powder marketed under the trade name Borazon, and indus¬ trial diamonds, such, for example, as the powders of Grade MB β -11 having a hardness of 10 on the Mohs scale and ranging from 5,500 to 7,000 on the Knoop scale. Crystalline alumina, with or without the addition of Ti0- 2 , Fe^, Si0 2 and Zr0 2 . having a hardness of preferably about 9 (Mohs scale1 and for most purposes at least 5, and natural abrasive materials such as diamond of the bort variety, emery, garnet, pumice - and the like may also be used. The foregoing particulate or granular abrasive .compositions and mixtures thereof are employed In one or more of the refractory plies of ceramic character 16; in one or more of the adhesive layers or plies 17; or plies, normally made exclusively of these abra- si e penetrant-resistant compositions, connected by a refrac¬ tory adhesive as described elrsewhere to each other, or posed between radiant reflective " plies or refractory plies. Where successive reflective plies, such as 12 and 14 are separated by one or more plies containing in ' significant quantities, or composed of, abrasive materials the reflective layers, such as l4a and 14b in Fig. 5 should not, most desirably incorpor¬ ate oppositely polarized electrical charges, as the abrasive materials do not provide the significant degree of insulation provided by while generally only semi-conductive electrically the refractory ceramic fiber containing plies described elsewhere herein, such for example, as the aluminosillcates. In any event, as envisioned herein, the abrasive materials are Into an integral ply using, desirably, the adhesive bond¬ ing agents of the adhesive plies 17, as characterized elsewhe herein. The thickness of " the penetrant ply where present wil normally be within the range of about 1/16 inch to about 1/4 Inch. The abrasive penetrant resistant ply will desirably contain from about 5 percent to about 70 percent, and prefer¬ ably 30 percent to 50 percent, abrasive composition with the remainder an inorganic refractory adhesive bonding agent such as described elsewhere herein. The proximate electrically charged oppositely polar¬ ized conductor plies must be separated by a ply constituting an effective Insulating layer under the circumstances of use, in any event. -_. h ~ - The presence of an abrasion penetration-resistant ply will not replace the purpose served by the presence of one or more ceramic fiber refractory plies. The abrasion penetration-resistant ply -is thus a supplement to, and not an alternative for, the' refractory ply 16. It tfill be evident that abrasion materials described hereinabove may be conveniently incorporated in the structural ply 15 (and 15a) as well. In an alternative and preferred embodiment intumes- cent materials, that is, compositions that swell in response to the application thereto of heat, are used as gasketing about cable entry means, for example, in the manner described hereinafter, and may also constitute the> strips 24 and 30 and angles 28 replacing the ceramic fibrous material proposed for this purpose as shown in the embodiment of Figs. 2, 3 and 4.. It has been found useful additionally to wrap the cables in this intumescent material at and proximate to the point of entry into the enclosure 200 (or 300) of the invention illus¬ trated in Figs. 6 to 11. It is also within the scope of the invention to utilize these intumescent materials as a jacketing material to protect cables from fire damage, running to or from the Enclosure 200. In addition, the laminates described may be used to form protective conduits, enclosing one or more of said cables, especially those which are vital to the integrity of the data processing system. Illustrated in the drawing of Figs. 5, 6 " , 7, 8, 9 and 10 is a transaction processing center 200 and components thereof coming within the ambit of the invention and incorpora¬ ting the composite laminate 1Q described hereinabove and further elaborated upon hereafter. Also illustrated in Figs. 11 and 12 are alternative embodiments of a transaction pro¬ cessing enclosure or module 400 adapted to secure Instrumen¬ tation of reduced dimensions, The larger enclosure 2Q0 comprises a housing or enclo- sure constituting a stationary vertical v.'all, one or more ac¬ cess means and one or more preferably slid ' ably * and arcuately rotatable closure means. Two , an exterior and interior, closure means 224 and 225, respectively, are shown in Figs. 7 and 8 in the closed position, and thus, occluding the access means-. The lateral margins of these closure means are in registry with the rear stationary vertical wall 222. In the completely open position the closure means 224 and 225 are preferably disposed respectively outside and within the wall ■ 222, moving in a path defining an axis substantially identical to that o the arcuate wall 222. The stationary wall or housing 222 and closure means 224 and 225, in a preferred em¬ bodiment, define semi-cylindrical panels as is evident, adapted in the closed state to seal the interior of the unit 200 from the exterior. The side wall 222 may assume a variety of other configurations in generally less preferred embodiments as may the closure means. ' ' - - The housing 222 and closure means 225 are, in fact, panels 10 adapted to fit the unit 200, and particularly those of the conformation shown in Fig. 4. This cylindrical or semi-cylindrical construction of the panel 10 and housing 222 and closure means or panel 225 is particularly preferred, not only for economy of space, but because it imparts the greatest reflective capacity to the outermost and innermost reflective plies 12 and 14 of a transaction processing enclosure such as disclosed in U.S. patent 4,121,523 of one of the inventors herein and the copending divisional application thereof, Serial No. 952,782 filed October 19, 1978. - The closure means may be segmented horizontally to give access selectively to different levels of the module's interior and may also Include a smaller, secondary access means and secondary closure means also formed of the laminate. The laminate structure is continued into the upper module partition 27 and Into the base 284. The construction is such that the individual plies of reflective and, desirably, bullet or projectile resistant outer layer 12, Inner reflective l 1 and the related refractory plies and structural compon¬ ents of the housing or vertical wall 222, " are'continuous with each other. This continuity does not ordinarily exist with - - - - respect to marginal interrelationship of the access means and housing wall 222, but a trim or molding of fibrous ceramic material or alternatively, and preferably, an Intumescent composition as described hereinbelow, is provided along the margins of the access means and various cable entries in the manner described hereinafter. In the closed state the closure means 225 are in registry at their lateral borders with the closure plates 202 as shown in Fig. 7. These closure plates are also formed of the composite laminate 10 and have a trim - or gasketing of ceramic fibrous refractory composition or preferably an intumescent material, as shovm In Figs. 9 and 10 and as described in greater detail hereinafter. Where employed to house a bank transaction proces- ' sing device, such as automatic paying or receiving machines or to constitute a bank vault the module or transaction pro¬ cessing center 200 must comply with the burglary-resistant material for such machines including the use of 3/8 inch thick nickel stainless steel meeting the requirements of. ' Regulation P or in lieu thereof. the requirements of ASTM A 16770, or such equivalent materials authorized, or as may otherwise be author¬ ized hereinafter from time to time, by the Board of Governors of the Federal Reserve System or other appropriate authority in the.United -States -or other country where the apparatus of the "invention is to be employed. Where employed to house an automatic banking machine, e.g. the vault 230 thereof will ordinarily be disposed under the transaction face 232 as shown in Fig. 6,wherein the clo- sure means 225 is shown to be horizontally segmented to pro¬ vide upper (225a) and."lower (225b) components. The upper closure means component 225a may be permitted to stay open during banking hours and closed at other times. Where access is desired for servicing of the machine or vault positioned under the automatic teller or bank machine face 232, shown schematically in Fig. 6 } the lower closure means 225b Is - * - rotated to the open position alone or In conjunction with the upper closure means 225a. The closure means 224, where present, may be similarly segmented and rotated. The border between the upper (225a) and lower closure means (.225b) is conveniently unmodified so that the plies of the laminate or panel forming the two components of the closure means are continuous when the plies are simul- taneously in the open or closed state. In addition, the transaction processing center 200 will normally include, in a preferred embodiment, turntable means, plate or platform 244, disposed for rotation within the housing and upon which the electronic data processing equipment, banking machinery or the like is mounted and to which all parts thereof access can be had through a single access means on the front of the " module that is closed by the closure means 224 and 225. It is, of course, feasible in accordance with the invention to provide a transaction processing enclosure of a. size sufficient to permit entry of one or more operators or other persons or to modify an existing room to embody the features described herein. The turntable means, while not essential for some purposes, represents a significantly preferred component of the enclosure 200 Cor indeed of enclosure 400 described else¬ where herein and shown in Figs. 12 and 13) in that it assures the minimum required access, and correspondingly the greatest continuous uninterrupted housing surface, with the concomitant benefits in terms of insulation, security, diffusion, and the like In the manner described herein. The closure means.-224 are mounted conveniently In a track 226a formed on- the perimeter of the upper module parti¬ tion 27 and additionally or alternatively (shown as 226b) in the perimeter of the module base 284 to enclose or provide access to the housed equipment. The closure means 225 may be similarly mounted but Is preferably disposed in slidable relation using ballbearings 305 in the manner shown in Fig. 9_, As will be evident In this context, the turntable 244 is essentially flat, may have other supplemental turntables 246 and 248 independently superimposed within * the housing 222 as shown in the free-standing embodiment of Fig. 7 and may be round or circular in horizontal conformation. The turntable 244 or indeed supplemental turntable such as 246 and 248 and their surfaces may at the same time be specially modified to accommodate specialized apparatus as desired . The internally disposed closure means 225 and the sum . of any horizontally segmented subdivisions thereof 225a and 225b, such as seen in Fig. 6, may terminate below the periphery of the platform 284 as shown in Fig. 7 at its lower margin and, in one embodiment , in the outer margin of the rotation plate 280 with which it is in fixed engagement at its upper end. In the significantly preferred embodiments of the present invention, where electronic data processing- equipment or other sensitive apparatus is to be maintained free of radio frequency interference , in a controlled, dis¬ crete, Isolated and protected environment or where a banking machine such as an automatic paying - or receiving machine is enclosed within the module the inner closure means or access element 225 will extend preferably from the upper module part tion 274 by means of a flange ' 289 to the base 284 in order to comply In the United States of America with the requirements • bf the Federal Reserve Board as expressed, for example , In Regulation P. A significantly preferred embodiment of the closure means 225 is 'shown in Figs . 8 and 9 and described in detail hereinbelow. The turntable 244 and the supplemental turntables 246 and 248 where present as shown, provide easy access to the rear or any other aspect of the electrical or electronic data processing apparatus present in the module for servicing or the like at the same site through the same access means used for operation of the contained apparatus or entry of persons thereinto; accomplishing a unique economy of function, utili¬ zation of space, and, most particularly, limited closure means requiring sealing to assure isolation and proection of the interior of the enclosure 200 from the outside at a level con¬ sistent with, -that afforded by the laminated housing 222 and the panel forming the closure means- 225. Rotation of the turntable can be integrated selectively through a standard control panel (not shown) wirh opening of one or all segments of the secondary closure means. Ramps from the interior of the booth to the exterior for removal of the contained equip¬ ment for servicing may also be used in a significantly less preferred but operative embodiment. All of the functions thus far described as well as securing or latching and unlatching of the booth or module are accomplished conveniently by means of conventional elec¬ trical circuitry well-known to one skilled in the art or anu- ally with conventional mechanical locking systems. The turntable Is, in any event, conveniently and Independently controlled by operation of a drive motor 250 and drive shaft 252 interconnected through a standard system of bevelled gears 25 ; the drive shaft being ~ mounted on the undersurface of the turntable 244 at its axis of rotation as illustrated in the free-standing module of Fig. 7- Alterna¬ tively, the rotation of the turntable may be accomplished by a variety- of mechanical means obvious to those skilled In the art or by manual means. The position of the turntable may be fixed by an externally operated brake or locking mechanism (not shown) on the drive shaft 252. A similar drive mechanism 270 is mounted atop the upper module, partition 27 disposed within the supra module housing 275 in the embodiment illustrated in Fig. 6 by means, for example, of the rotatable shaft 27 which extends through said partition 274 in which it is independently rotatably mounted by means of a bearing assembly (not shown) to termi- nate in the axis of the circular horizontally disposed upper module or rotation plate 280 which is in fixed engagement with said shaft 276 and rotated thereby. The inner protective closure means 225 of the module 200 Is preferably in contiguous contact or registry with the periphery of the rotatable upper module plate 280, as noted hereinabove., and may be operated manually as well as electri- cally or mechanically. When the inner closure means 225 is divided " horizontally the support and drive.mechanism for the upper may be identical to that described hereinabove for 225 ^J as a single unit. The support and drive mechanism for the closure means 225b will consist of an arcuate track on the base 284, of generally circular shape with internal drive rin (not shown) and, a drive motor (not shovm). A particularly preferred modification of this embodiment is depicted in Fig. 8. Additional modes of operation will be apparent, as well, to those skilled in the art. Of course, manual operation in conjunction with an electrical control means or as an over-ri method of operation of said closure means in event of failure of said drive mechanism is also an alternative. While des-. cribed with respect to the inner closure means 225, it will be evident that the outer closure means 224 can be similarly segmented and the odes of operation enunciated hereinabove with respect to the inner secondary closure means 225 applied to the outer closure means as- well.. The lateral margins of the closure means 225 are registrable with the stationary wall 222 in the open state and its lower edges with the base 284 in a preferred embodiment as also described herein. The upper margins are also normally in registry with the ceiling or supra module partition 27 In a preferred embodiment. The stationary wall 222 is, in turn, secured within the outer mar¬ gin of the upper or supra module partition 2 4 exterior to the outer periphery of the plate 280 and is, in a significantl preferred embodiment, continuous therewith and with the floor or base 284 upon which the unit or module is located as des¬ cribed hereinabove so that each ply or " each panel-'is continuous about the periphery of the stationary wall 222, ceiling or the upper module partition 274 and base 284 except where Inter¬ rupted by cable entry"means, a rotatable shaft 276 and access means 225, and the like. In a further and particularly preferred embodiment shown in Fig. 8 the access means is secured by the closure means 225 in a manner which assures sustained protection of the transaction processing enclosure by preventing penetration of the enclosure 200 by, for example, heat, cold, fire, smoke, water or moisture about the periphery of "the closure means 225- -- - There is provided in this modification a protective system in the seams about the closure means equivalent in effectiveness to, or approaching, that provided by the lami¬ nate enclosure of the vertical housing 222 and panel of the 5 closure means 225, the supra module housing 274 and the base 284. For this purpose, there is provided flanges 290 and 291, respectively, extending from the ceiling 27 and the base 28*i and occurring in spaced parallel "" .alignment to the upper 10 and lower margins 297 and 298 respectively of the closure means 225. The flanges 290 and 291 are integral with the ceil¬ ing 274 and base 284 respectively, of the enclosure 200, include the outer reflective ply 12, including the support angle clips 15a, the refractory layer 16, structural ply 15 and the adhe- 5 sive layers or plies (not shown) disposed between the foregoing plies. The angle clips 15a represent a further modification within the contemplation of the invention in that these clips are supplementary and optional structural metal support ele¬ ments and are separated preferably from the reflective ply 12 0 by a refractory adhesive such as described elsewhere herein. " These clips 15a are necessarily separated from the primary support elements 15 by a refractory ply or element 16 in accor¬ dance with the invention. The upper and lower edges of the closure means 225 5 terminate in the ribs 297 and 298 extending perpendicularly in relation to the closure means 225 and the flanges 2 0 and 291. Extending from the Inner surface of each flange 290 and 291 is a self-lubricating or reduced friction seal washer member 295 that impinges upon the exterior surfaces of the edges Q of the closure means and permits substantially free movement of the closure means relative thereto. This sealing member is de¬ sirably formed of a normally resilient flexible poly (tetra- fluoroethylene) sold by DuPont Corporation under the trade name TΞFLOK " , rubber, sillcone rubber, ABS butadiene-styrene, or like material well-known to those skilled In the art and particularly- preferred are those materials-having a melting point normally of at least 250°F and up to preferably of about 45C°F. -57- A highly effective modification of this sealing, means is one in which the orifice 295(a) defined along the interior of the washer member 295 retained in the narrow necked recesses " 299 of the ribs 297 and 298 is inflatable c to exert a pressure of 5 pounds per square inch psi to 100 psi; will conform to uneven surfaces and a barrier to moistur contaminants and particulate matter and to differences in pre sure inside and outside the enclosure seal is inflated with a fluid, normally air, transmitted from a pressure-regulated supply system. The seal can be deflated, as well, when desired. Inflation of the gaskets or seals of this general type is known to those skilled in the art. Inflatable sealin means are available, by way of illustration, from the Presray Corporation, Pawling, New York. Mounted upon .the outer surface of the upper lower margins of the closure means adjacent but inwardly of the ribs 297- and 298 are the intumescent lips or elements 300 and 301, respectively. In spaced relation thereto on the interior surfaces of the flanges 290 and 291 are the complementary Intumescent lips or elements 302 and 303 3 respectively. In a further embodiment (not shown) the sealing member 295 may be incorporated in one of the lips or the intumescent gasketing means e.g. 300 or 302, and formed conveniently by dual extru¬ sion techniques well-known to those skilled in the art. In the embodiment of the invention shown in Fig. 8 the slidable rotation of the closure mean ' s 225 is " accomplished by means of ball bearings 305 disposed in the track 307 formed in the structural element 15 of the housing base 284. It will be evident that other ^ means well-known to those skilled in the art for slidable ' opening and closing of the closure means ma also be employed. These methods which may include rollers, slideways, and the like, involve a maintenance of contiguous relation between the housing and closure means in the act of opening and closing of the latter means as well as when it is at rest and are embraced herein by the terms "sliding", "slidable" and grammatical variations thereof. It will be evident, as well, that the closure means shovm to operate — j r - - — horizontally may be " modified to operate vertically or at an angle therefrom; with the associated sealing ring, washer or theiike flange and like construction rearranged to a vertical or other disposition identical to that of the closure means 225. Illustratively, the closure means 225 may be reduced In size and be surrounded by the stationary vertical housing 222; rather than abutting the ceiling 274 and base 284 of the enclosure. In addition, the closure means of reduced size ma be mounted in a removable panel forming a portion of the sta- tionary vertical side wall or housing 222. In this embodiment the panel of the closure means may be of guillotine construc¬ tion sucn as described in U.S. patent "4,121,523 and copending application Serial No. 952,782 filed November 19. 1978 by one of the inventors herein and incorporated by reference herein. The closure means is incorporated -by reference herein. The closure means Is operated electrically, mechanically, electro- mechanlcally or manually, for example. The lateral stop elements 202a of the housing 222_ referred to in context with Fig. 8 hereinabove "' are shown In " further detail in Figs. lQaandl ' Obin relation to the closure means flanges 310. The stop element closure means flanges 310 as shovm illustratively in Figs. 10a and 10b, complement on th lateral or vertical borders of the closure means 225 depicted in Figs. 2, 8 and 9 s the protective system of the contiguous slldeable margins or borders of the " closure means 225 describe with particular reference to Fig. 8 hereinabove.- The closure means 225 is shown in a nearby closed position in Fig.10 , with the housing stop elements 202a and 202b including the intumes¬ cent elements 310 and. ^ 313 respectively adapted to impinge upon the intumescent elements 3H and 312 abutting the closure means flanges 315a and 315b respectively. It will be evident that in the closed position portrayed in Fig.lQ, the foregoing elements play the same role essentially in the event of expo¬ sure to fire or elevated temperatures as that play by the pro- tective system disposed about the upper and lower slidable margins of the closure means 225 des-crlbed with particular reference to Fig. 8 hereinabove. The laminar construction of the closure means 225 and the adjacent housing wall 222 is again illustrated in F 10a and b. Thus, as represented, there is in each instance outer reflective ply 12, an intermediate ceramic fibrous 5 refractory ply 16 and an inner protected structural element 15. Ceramic adhesive plies (not shown) are also present in each instance. The terminal borders 320 of the housing 222 defining the lateral borders of the access means comprise ceramic fibrous refractory or intumescent strips 24 adapted 0 to provide a protective trim to the exposed borders 320 of the housing 222. As Indicated elsewhere herein, a preferred embodim for many purposes will include at least one interior radiant heat reflective ply and alternatively, additionally, or pref ably In combination, ah electrically ^ conductive ply connecte with a power source and alarm and monitoring system as other wise described herein. ' A particularly preferred single ply encompassing both the functions of electrical conductivity an radiant heat reflection is a continuous copper lamina. Com- plementing the Interior electrically conductive ply is the continuous outer ply 12 made of an electrically conductive material such as impact resistant, radiant heat reflective .steel. The ceramic fibrous refractory plies and desirably the ceramic adhesive plies are electrically non-conductive providing insulation for the electrically conductive plies. It will be noted that the closure means- flange 315a which is positioned exterior to the stop element 202a and Includes the intumescent element 310 also has an additional intumescent element 324 exterior to the seal (295) bearing flange 315a that will intumesce to occlude the passage betwee the housing wall 222 and closure means 225 to serve an effect similar to that of the elements 311 and 313 of Figs. 10a and b and 300 and 302 and 301 and 303 of Fig. 9. ' As described here-r- inabove the intumescent elements 310 and 312 will serve to provide the necessary protection to the enclosure's (200) interior in any event. The lateral margins o.f all of the foregoing paired intumescent elements, and the unpaired elemen _ 324, of Figs. 9 and 10 are free to permit free swelling into and occlusion of the passages Into which they extend without occlusion at normal ambient temperatures. The housing 222 and closure means 225 of Figs.10a •5 and 10b also manifest the unique laminar structure of the Invention including an outer reflective layer 12, intermediate ceramic fibrous refractory ply 16 and structural ply 15 with interposed piles of ceramic refractory adhesive (not shown). In order, however, to avoid the distribution of heat along 10 the conductive surface of the structural element 15 from the exterior of the enclosure 200 adjacent the terminal ends 320 of the housing about the access means and the stop ele¬ ments 202a and 202b in Figs.10a and 10b respectively into the interior of the enclosure the structural element 15 is inter- 15 rupted In each instance by the ceramic fibrous refractory heat stop component 380.. A similar laminar ' construction and like elements 38O appear in " the structural elements 15 of the hous¬ ing flanges 290 and 291 and adjacent the -closure means flanges 294 a d 298, respectively. 20 It is noted " that while the intumescent components are said to stand free at their lateral borders it will be evident that they abut support surfaces in each instance of their use as illustrated in Figs. 8,10a and -10b anc it ^ s indeed preferred that they be bonded thereto " for most 25 purposes consistent with this invention using a ceramic refractory adhesive such as described elsewhere herein for this purpose. The seal 295 assures protection of the module interior at temperatures of up to 450 f or such other ele¬ 30. vated temperature at which the seal normally degrades. The intumescent elements 300 and 302, 301 and 303, and 310 and 312, 311 and 313 and 324 are adapted to expand and Impinge upon one another occluding the passage therebetween at a temperature below that at which the seal degrades, thus 5 protecting the seal, but even if the temperature attained at _ -. . - - - the seal is sufficient to destroy it, the abutting intumes¬ cent elements inhibit the temperature increase, as well as the passage of noxious pollutants such as smoke, and contin the protection and stable predetermined environment of the 5 contained equipment. A preferred intumescent composition in accordance with the invention is vulcanized rubber, and particularly one containing ceramic refractory components, that expands commencing at about 250°F, with the foregoing intumescent 10 elements coming into contact where paired with complete occlusion of the intervening space at about 350 F. The foregoing arrangemen for sealing the margins of the access means along the path of movement of the closure means between an open and closed position while permitting free and fluid movement thereof in normal prac- . tice and in the absence of untoward circumstances as describe in context with Fig. 8 hereinabove can be repeated with the outer closure means 224 as well. An outer closure means 20 224 is, in fact, shown by way of illustration in Figs.10a and 10b. Particularly preferred of the intumescent materials for use herein are the vulcanized rubbers and ceramic composites having a density of 96 lbs/cu. ft; a compression 25 set . (ASTM D-395B) of 25% maximum; a Shore A hardness of 45- 75 and a limited oxygen index (ASTM D 2863-74) of 65%; illustrative of which is 3M FS-195 sheets manufactured by the Minnesota Mining and ' Manufacturing Company, St. Paul Minnesota. 3.0 - The intumescent elements, as indicated hereinabove unconfined about their lateral margins and employing the preferred intumescent vulcanized rubber and ceramic particu- late composite, referred to above, will manifest a multi¬ dimensional expansion of 5 to 11 times, sufficient to provide, 5 as also indicated, a nexus of the paired elements at about 350 F (175 C) . Since, as indicated,expansion occurs at as little as 250°F (120°C) the space between the paired ele¬ ments and the element 324 and the interior housing surface 5 at each of the margins of the closure means, the initial multidimensional thickness of ambient room temperature e.g. 22 C . and other conditions may be varied substantially. The expanded and mutually _impj_jτσing. ' elements 300 and 302 for example will, using the preferred vulcanized rubber described hereinabove, act as an effective refractory material at temperatures up to 1740°F (950°C) with a strength at expan¬ sion of up to 500 psi. The elements will have a weight loss_of 25 percent and a maximum reduction in density of 10 lbs/cu. ft. Normal- 15 ly, -the- expanded density will not be -so reduced because it is intended in accordance with the invention that the expanded elements exert pressure on each other to eliminate any possible passage therebetween for air, smoke, fire or heat. In this latter regard the preferred intumescent material 20 2 o will demonstrate a thermal conductivity in Btu/hr. ft F. of .33 at 70°F.; 0.51 at 613°F and 0.66 at 1130°F., more than sufficient to protect any contained banking equipment and electronic data processing equipment in the transaction - - processing- enclosure 200. Further illustrative of intumescent sealants for use herein and which Intumesce at high temperatures are those compounded of elastomers with " 4 percent to 30 percent by weight vermiculite as blowing agents such as described by , 0 Hons-Oliver et al in Federal Republic of Germany Offlenle- gunschrift 2,729,838 incorporated by reference herein. A more specific illustration of these compounds is one con¬ taining, in parts by weight, 100 parts of neoprene rubber, 11 parts of conventional vulcanizing agents, 2 parts anti- 5 oxidant, 40 parts Al-,0.,, 10 parts chlorinated paraffin, 5 parts SbO-,, 8 parts decabromobiphenyl, 40, parts kaolin, 40 parts vermiculite, and 15 grains of isodecyl diphenyl phosphite o as vitrifying agent. The composition is vulcanized at 160 C. Other conventional intumescent materials may also be us so long as they intumesce and occlude the passages describe herein below that temperature at which the self-lubricating or low friction sealing ring melts or is otherwise degraded or destroyed. It is noted that when the intumescent elements 300, 301, 302, 303, 311, 312, 313 and 324 are in their fully expanded state, the closure means will be immovable. It is necessary therefore that the closure means be closed at the onset of any fire or any condition giving rise to an elevate temperature outside the module 200; as. ell as at the incept of any acts of vandalism or other adverse circumstances. For this reason, in accordance further with the practice of the invention, the closure means 225 (and 224 where present) may be rendered responsive and activated to a closed positio by " alarm, thermostat, smoke detector or the like employing conventional circuitry, responding to fire, elevated tempera¬ tures, smoke seismic shock from phsyical attack or unauthoriz or unprogrammed attempts to gain access to the interior of the processing unit 200, or be closed and opened only when operational or service access is required for the equipment housed therein. It is also within- the scope of this Invention, to Include conductive plies 14 particularly when comprising a mesh structure, as described hereinabove within the embodi¬ ment of the intumescent" elements, including those elements protecting areas of the housing through which cables are transmitted, to provide a shielding system to the trans¬ mission of electromagnetic energy to or from the housing. In addition, the washer members 295, especially when Inflat¬ able, also includes within its structure, a continuous con¬ ductive ply 14, These plies may be converted to appropriate plies of the laminate 10 including the outer reflective ply 12 or an Interior conductive ply 14, ' he closure means is operated desirably in con¬ junction with an alarm system where present in the enclosure. The enclosure 200 may thus have a monitoring and alarm syste maintained throughout the enclosure 200 by means, illustra- tively, of the electrically conductive outer ply 12 having a grounding component 608 and electrically conductive struc¬ tural ply 15 connected in series with an alarm 620 and a power source 6l6 to a ground wire 6l2, as described elsewher herein. With continued reference to the transaction proces ing module or enclosure 200, and more particularly, with reference to the free-standing manifestation or embodiment of Figs. 6 through 10 it will be seen that the upper or supr module housing or ceiling 274 defines entry into a hung ceil* ing 286, which contains, as shown diagrammatically in Figs. 5 and 6, the conventional heat, ventilation and air .conditio ing systems as well as electrical and communication lines int which the module may be grafter to provice, encapsulated by ; the module, for example, the controlled environment necessary to the enclosure's operation. The riser duct 29.0 serves to effect transmission of the foregoing environmental components to the interior of the module 200 In the embodiment of Figs. 6 and 7- The upper module partition 274 is perforated as shown in Fig. 10 for the purpose of transmitting the flow of gaseous -components, normally air of controlled temperature an humidity, through the enclosure 200 iri one embodiment of the invention. The module plat.e 280 is also perforated desirably to assure even and rapid distribution of the foregoing gaseou components throughout- the unit 20Q, Ducts (not shown) are also readily provided in alternative embodiments for distribu ing air, heat, ventilation, and air-conditioning through the base 284 of the enclosure 200 with perforation thereof and the plate 244. It is also consistent with the foregoing descrip¬ tion that individual units suitable for securing the necessary atmospheric control be placed within the supra module housing or adjacent to the enclosure 274 for delivery to the module Interior or chamber wherein the apparatus 230 is located. -6.5- Where , as is normally the case the modular com ¬ ponents are perforated as shown in Fig . 11 for the trans ¬ miss ion of gaseous components , the opening 349 may be pro ¬ jected by dampers 35Q constructed of the laminate 10. The 5 dampers are advantageously mounted in proximity to the openings 349 and activated in response to the detection of a fire , elevated temperatures or other adverse conditions as characterized elsewhere herein to occlude the " opening 349. 10 Illustratively, the damper. 350 is mounted on slide channels 351 and driven , by a power train consisting of a gear tra ks {not shown) affixed to a damper gear (not shown) , .which is conveniently meshed in one embodiment to a pinion gear 353 which is rotated by a drive shaft 354 " and motor 355. • 5 The damper 351 may fitted with an outer intumes¬ cent. gasket layer 356 and pliant bearing seal 357 to provide a fluid and refractory seal while permitting an adequate operating tolerance for the damper 350 ' in each instance of It s occurrence as it is moved slideably on the undersurface of the supra module partition on ceiling 274 . Means of fire detection 294 , fire suppression 295 , and motor control unit 297 and a source of emergency power 299 for these systems are placed in the supra modular housing as shown diagrammatically in Fig . 7 wi thout affecting materially the ease of assembly, disassembly or mobility of the module 200 . Alternatively, " these elements may be located ' below the turntable 244- on the base 284 of the module 200. A . particular advantage of the transaction process¬ ing center 200 of the invention is that the entire environ- ment of a room in which the units are disposed need not be subjected to the vigorous controlled conditions and energy replenishing requirements of the transaction processing centers where electronic data processing equipment is housed. Ingress to and egress from any room in which a computer, -for example, is housed , can take place freely and yet each - module is also protected against vandalism. Each exterior closure means 224 , which may be transparent where present , and interior closure means 225 3 is subj ect to latching in a conventional manner well-known to those skilled in the art to which this invention ' ertains . At the same time any desired piece of electronic data processing equipment can b readily removed from one location with its module and in¬ stalled immediately elsewhere by "plugging" of the enclosur into existing heat, ventilation and air-conditioning lines . When an enclosure 200 is equipped with its own heating, ventilating and air-conditioning system, it may simply be connected to a conventional electrical source. Due to current United States energy conservation rules , ' wherein office environments must be maintained at significantly elevated or reduced temperatures in each season, use of the module 200 permits the observance of these governmental regulations while providing the appropriate environment for the contained equipment . An extensible " ramp may also be employed for instal- lation and removal of any data or transaction processing equipment from a module or booth where the turntable, when present , upon which the equipment is placed is above the level of the floor . There is shown in Figs . - 12 and 13 of the drawing a protective housing 400 for use with more diminutive banking and electronic data processing apparatus than that contem¬ plated hereinabove. Illustrative of this equipment is a tabletop computer ter inal or microcomputer 404 indicated diagrammatically in the foregoing Figs . --12 and 13 - The transaction processing unit 400 is composed of several, or preferably a single, panel 10 forming a stationary wall 405 comprising in a preferred embodiment, an outer radi ant, reflective ply 12 such as described elsewhere herein, a fibrous ceramic refractory ply 16, and the Interiorly dis- posed structural ply 15 with intervening-.ceramic adhesive plies 17 such as described in Fig . 1 ; the several pl ies ^ an resulting panel assuming a spherical conformation in a pre¬ ferred embodiment.' Successive laminae of refractive fibrou ceramic material 16 and 18, and radiant reflective plies 12 and 14 may also be included in a further and preferred 5 embodiments utilizing the panel, of Fig.- 2 or Fig. 4, by way of illustration. A plurality of closure means may occupy the means of access-to the interior of the enclosure 400, such as described with respect to the enclosure 200, The inner closure means 4θo shovm in Fig- 13 in the closed 0 state and In Fig. 12 in the open state is again formed of t composite laminate such, as the panel 10 of Figs. 1, 2, 3 or 4, for example, curved to adapt to the configuration of the unit 400 and mounted about a common vertical axis with that of the stationary wall or housing 405. ' The preferred rotatable closure means 4θ6 is * slidably movable about the foregoing axis and is mounted for this mov ment with a self-lubricating seal such as that (293) depicte hereinabove with reference to the closure means of Figs-, 8 and 9 and intumescent elements Cnot 'shown) as well to provid a system impervious to passage of both solid, and especially particulate and fluid materials about the upper and lower margins of the closure means 406 as described with respect to the free-standing transaction processing enclosure 200 described hereinabove. The lateral borders are protected by a closure plate (not shown) of the type 202 of Fig. 6, and t system described with respect thereto in Fig. 9 ' hereinabove. Similarly, the housed equipment may be, and is desirably, mounted oji a turntable 10. In some applica ¬ tions, due to the extensive variations in size of such diminutive equipment, an extensible platform or. the like in association with a service access panel formed in the housing may he employed in lieu of a turntable to provide the necessary access for servicing of the equipment housed within the unit 4-00. In like manner, as observed herein- above, certain of the embodiments of thβ-larger enclosure 200, may omit use of the turntable where the housed equipment requires infrequent service or operator access or is otherwise poorly adapted to rotation as where a great number of non-pliant cables penetrate _the__enclo- _ sure from a variety of aspects. The lateral margins of the closure means are provided with intumescent gaskets 5 as are the top and base margins -in the manner described hereinabove with respect to the larger enclosure 200. Means of ventilation, such as a blower assembly, air- conditioning, humidity and temperature control equipment, detection and a fire detection element and the like are 10 conveniently incorporated within the enclosure 00 or its base Af-20 with suitable duct systems .where necessary or desirable and provided in the manner described with respect to the embodiment of .Figs. 5 to 7; using activatin means desirably to move the closure means to a closed 15 position in response to a threatening and adverse external environment. The inner closure means θ6 may be mounted so as to revolve about a horizontal or intermediate axis between the horizontal and vertical planes, as well. The general 0^h pe of the enclosure is shown to be spherical in the - preferred embodiment of Figs. 9 and 10. It is appreciated, in any event, that a variety of shapes can be utilized In defining the configuration of the enclosure 4-00 and that the configuration of the stationary wall ^- " 05 1 e.g. 5 spherical, and the closure means 4-07, e.g. hemispherical or arcuate, will depend In large measure on the size of the computer terminal or micro-computer kθk enclosed. The closure means 4-06 may otherwise be moved manually or by means of a drive element containing a slip clutch to D stop arcuate motion of the Inner closure means or shield -4-06, when Its path Is obstructed. Advantageously, the enclosure 00 may be mounted on a counter or desk top or on a supporting surface capable of being adjusted to any desired height. :' Cable and duct entries (not shovm) may be provided not only in the ceiling 274- of the transaction processing center 200 or the top of t e sma er un an bases 284 and 420 of the large C200) and small C400) units, respectively, as noted hereinabove, but in the sidewalls thereof in both" instances. These cable and duct entries, 5 . providing for environmental protection, control and the like as characterized elsevhere herein ' are desirably enveloped by intumescent gaskets wherein the intumescent refractory material is such as- described hereinabove. A significant advantage in the use of the composit panels 10 of the invention to house electrical equipment is the isolation from one another of the Internal and external conductive surfaces in a preferred embodiment as described elsewhere herein. As noted the_electrically conductive piles may be independently grounded eliminating the transmission of abnormal elect-rical current from the - internal surface to the exterior of the enclosure; avoidin the possibility of accidentally exposing a passer-by to electrical injury. In-addition the metal components within the composite panel have a constant resistance, dependent on the size and composition of the individual piles of the laminate. Continuous of periodic movement of the resis¬ tance across the laminate of housing or closure means ■ reveals and measures penetration of the panel structure due to alteration of the resistance constant. This feature permits ready detection of attempts to gain forceful entry into the enclosures 200 and 400 which can be readily reported electrically, by way of illustration, to a remote monitoring source or alarm system as also described elsewher herein with respect to a preferred embodiment of the inven¬ tion. The enclosures of the present invention have application to storage and containment of conventional paper files, currency, microfilm, jewelry and other valu- ables as well as unique utility in preservation of magnetic tapes, disk packs, microprocessor chips, characterized herein for convenience as "peripheral electronic data " " ft processing equipment". The invention has application as well to bank vaults, automatic tellers' units and dispensing equipment dealing, for example, in currency, tickets and other valuables, referred to herein as "banking equipment", and as noted elsewhere, herein, has particular utility as well for containment of communications apparatus, technical precision scientific equipment, hydrogen lasers, and conven¬ tional "electronic data processing equipment", which term is intended to include computer main frames, terminals and other standard peripheral devices. The following examples are further illustrative of the invention: EXAMPLE I A composite panel for use In a transaction processing center and constructed in accordance with Fig. 4 having an outer radiant reflective lamina 12 and an Inner radiant reflec¬ tive ply 14 and ceramLc fibrous plies 16 and 18 disposed on the Interior or each of said radiant reflective plies and a structural ply 15 disposed therebetween was tested to deter- mine its heat transfer characteristics. The radiant reflec¬ tive metal plies were formed of 22 gauge stainless steel type 410: the structural ply was 16 gauge cold rolled steel; the fibrous ceramic refractory plies were composed of four layers of ceramic fibrous paper of 0.125 inch thickness; and all of the foregoing plies were bonded to one another by piles of ceramic refractory adhesive. The fibrous plies have the following composition: Component % By Weight A1 2 0 3 51.7 Si0 2 47.6 Na 2 0 0.3 B 2°3 0.15 Fe 2 0 3 0.Q2 e Inorganics 0.2 The fibers of the ceramic refractory paper are up to 1 inch in length and have a mean average diameter thickness of 2 to 3 microns. The melting point of this paper is 326θ°F. The paper is made from washed fibers from which the unfiberize shot is removed by washing. The washed wet fibers are then formed into a flexible, 'light weight paper or sheet by a Foudrinier processing machine. The ceramic refractory adhesive plies interposed be¬ tween and bonding the foregoing radiant reflective, refractor and structural plies to one another have a total thickness of from 1.00 to 1.25 Inch. The adhesive employed has a chemi cal composition as follows: Component % By 1height A1 2 0 3 44 SSII0O 2^ " 54 a 2 0 0, .8 B 2°2 0, .6 MgO 0, ,4 e 2 0 3 0. .0.4 Trace Inorganics 0.. ,2 The adhesive is applied as an aqueous paste in an approximate thickness of .060 inch on each side of each re¬ fractory ply; providing an additional ply to the panels in each instance.
