Abstract: 1,180,234. Seals for treatment chambers, sterilising cabinets and respirators. NATIONAL RESEARCH DEVELOPMENT CORP. 23 Feb., 1967 [11 March, 1966], No. 10790/66. Headings A5G; A5R and AST. [Also in Divisions A3; B4; B7 and F2] A pressure-resisting seal for use in treatment chambers, sterilising cabinets and respirators comprises closure members formed of flexible sheet material, each member comprising a closure portion 11 and a pair of cheek portions 12 defining a concavity, the arrangement of the closure members being such that when inflated by pressurised fluid confined on one side thereof the closure portions extend inwardly from the aperture 14, the cheek portions 12 acting as ties to restrain the closure portions against the pressure of the fluid, and adjacent cheek portions of neighbouring closure members being urged together so as to provide a seal between adjacent members. The closure members may be made of nylon or rubberised fabric. The shape of the closure members may be modified to suit apertures of different shapes. Where the pressure on one side of the seal varies such that it is alternately less than and greater than that on the other side, a second set of closure members facing in the opposite direction to the closure members of the first set may be arranged therebetween, see Figs. 7, 8 (not shown). Such an arrangement may be used as a neck seal for "iron-lung" types of respirators, see Figs. 9 and 11 (not shown). In modifications, the second set of closure members is arranged so as to face the direction opposite to that which the first set faces and embrace the cheek portions of the members of the first set, see Figs. 12 and 13 (not shown), or be embraced thereby, see Figs. 14 and 15 (not shown). In yet another modification, see Fig. 16 each closure member 210 may be in the form of a conical bag provided with apertures 42, 43 and flaps 44, 45 such that in operation each flap acts to seal its corresponding aperture when the pressure inside the bag exceeds that outside the bag. The pressure-resisting seals may be used on sleeves into which oxygen-enriched air is fed for the treatment of burns or lacerated tissue on arms, see Fig. 19 (not shown). Another form of the seal comprises a single strip of flexible sheet material looped under rods and over blocks projecting from the inner periphery of an aperture, see Fig. 20 (not shown).

The small triangular shaped parts 39, 40 not covered by the roof light is closed with roofing material. Specification 713,972 is referred to.
Patent GB-721151-A (GB)
Title: Epoxyalkoxy aryl resins
IPC: C08G59/08
Filed: 1951-05-10
Abstract: A synthetic resin molecule consists of at least three units with the structure <FORM:0721151/IV (a)/1> in which R is hydrogen, alkyl, alkylene, aryl, aralkyl, alkaryl, cycloalkyl or furyl; X and Y are hydrogen, chlorine, alkyl or hydroxyl; R1 is chlorine, alkyl, aryl, aralkyl, alkaryl or cycloalkyl; at least one member of the group R1, X and Y is chlorine; and Z is hydrogen or an epoxyalkyl group with the formula <FORM:0721151/IV (a)/2> in which n is not greater than 8 and the unoccupied valencies are hydrogen or alkyl with not more than 7 carbon atoms, the total number of carbon atoms in the epoxyalkyl group not exceeding 10. There must be at least one epoxyalkyl group per polymer molecule. The products are prepared by reacting a chlorine substituted phenol-aldehyde condensate in alkaline medium with the desired proportion of a haloepoxyalkane.  Lists of suitable phenols and aldehydes are given.  They are condensed according to well-known procedures.  The molecular weight of the condensate may be controlled by varying the proportion of aldehyde to phenol and by adding small amounts of monofunctional phenols, e.g. 2,4-dichlorophenol.  Some of the phenolic hydroxyl groups in the phenol-aldehyde condensate may be etherified, e.g. with methyl chloride, isopropyl chloride, benzyl chloride or dimethyl sulphate or esterified with carboxylic acids, acid anhydrides, chlorides or esters before the reaction with haloepoxyalkane.  Suitable haloepoxyalkanes are epichlorhydrin, 1-chloro-2,3-epoxybutane, 1-chloro-3,4-epoxybutane, 2-chloro-3,4-epoxybutane, 1-chloro-2-methyl - 2,3 - epoxypropane, 1 - bromo - 2,3-epoxypentane, 2 - chloromethyl - 1,2 - epoxybutane, 1 - bromo - 4 - methyl - 3,4 - epoxypentane, 1 - bromo - 4 - ethyl - 2,3 - epoxypentane, 4 - chloro - 2 - methyl - 2,3 - epoxypentane, 1-chloro-2,3-epoxyoctane, 1-chloro-2-methyl-2,3-epoxyoctane, 1-chloro-2,3-epoxydecane. When the epoxyalkoxyaryl resins are to be used for cross-linking other polymers, e.g. cellulose acetate, cellulose ether-acetate, saponified polyvinyl acetate or polyamides, they should contain at least two epoxy groups per molecule.  When they are to be cross-linked with reaction polymers or coupled to give resins of higher molecular weight they may contain as little as one epoxy group per molecule. In the example p-chlorphenol is condensed with aqueous formaldehyde in presence of oxalic acid.  The product is dispersed in caustic soda solution heated to 70-80 DEG  C. and epichlorhydrin added with warming to 80-100 DEG  C.  The resin layer is separated from the aqueous one.  Specifications 721,149 and 721,153 are referred to.

Filed: 1955-04-19
Abstract: 806,165. Electric hot plates. GENERAL ELECTRIC CO., Ltd. April 19, 1956 [April 19, 1955], No. 11279/55. Class 39(3) An electric hot-plate especially with one or more elements of the sheathed wire type having a resistance wire insulated within a metal sheath has heat-absorbing means mounted below and spaced from the element to provide a heat leak so that leakage of current between the wire and sheath may be reduced when the element is in the red heat range, the arrangement of the element and the heatabsorbing means and the full load rating of the element being such that if the means were replaced by a reflecting surface, the temperature of the element in operation at full load would exceed its safe working limit. The heat-absorbing means may comprise a drip plate formed with a heat-absorbing and not a reflecting surface, e.g. the plate may be of black vitreous enamelled mild steel or may be of stainless or chromized steel with an oxidized or burnished surface. The underside of the elements may be completely open to a hot cupboard or warming space beneath the hob of a cooker, the hot cupboard thus forming the heat leak. In Fig. 3, the sheathed element 1 is carried by a steel spider 8 in a black enamelled or other heat-absorbing dish 2 on a back plate 3 and has current supply pins 4 and internal insulated leads 7 protected from below by a metal strip 6. The enamelled back plate 3 has two large apertures one on each side of the strip 6 to allow downward radiation of heat from the heatabsorbing dish 2. In Fig. 5, the heatabsorbing dish 2 is supported in a cooker by adjustable screws engaging parts 10 of the dish and by a ledge 11 of the terminal assembly 12. The dish 2 may alternatively be supported by an outward peripheral flange formed at its upper edge and resting on the hob of the cooker. The spider 13 supporting the element 1 extends into slots in the dish 2. These slots do not extend to the edge of the flange 16. When a hot cupboard 20 beneath an element 1 forms the heat sink, the element is carried by a spider 13 carried by an annulus 17 resting on the hob, the terminal assembly 12 being under the hob. A centrally apertured heat-absorbing drip tray 21 may however be supported well below the element, the tray 21 having a flange 23 entering a pocket 24 welded to the wall of the hot cupboard. The tray may conform to the shape of the element 1 or may extend wholly across the warming space under other apertured plates. In a modification of the structure shown in Fig. 5, the dish 2 rests in a ring support adjustably screwed to a flange on the terminal assembly 12.
