Title: Laminates containing silicone rubber
IPC: B32B27/00
Filed: 1959-10-09
Abstract: 870,003. Laminates. MIDLAND SILICONES Ltd. Oct. 9,1959 [Nov. 26, 1958], No. 34316/59. Drawings to Specification. Class 140. [Also in Groups VI, XV and XXVIII] A laminate of vulcanized silicone rubber and foamed polyvinyl formal resin is bonded together with a cured silicone adhesive. The silicone rubber and the foamed polyvinyl formal resin may be in the form of sheets or rods, or may be in the form of an outer ear or nose in which the silicone rubber forms the major part of the member and the polyvinyl formal layer is adjacent to the body and serves as a suturing anchor. The laminate may include multiple plies of silicone rubber and polyvinyl formal foam, or a layer of silicone rubber between two layers of polyvinyl formal resin. The polyvinyl formal foam may be prepared by beating or agitating an aqueous solution of polyvinyl alcohol to disperse bubbles therethrough and reacting with formaldehyde in the presence of an acid catalyst such as sulphuric acid. The silicone rubber may be one in which an organopolysiloxane is substituted with hydrocarbon radicals, such as methyl, ethyl, propyl, octadecyl, vinyl, allyl or phenyl, or with halogenated hydrocarbon radicals such as trifluoropropyl, trifluorotolyl or chlorophenyl. The filler may be a silica such as diatomaceous earth, a fume silica, a silica aerogel or a silica xerogel, and may be coated with organosilyl groups by treating the powdered silica with chlorosilanes or by reacting silica organogels with chlorosilanes and siloxanes as in Specification 783,868. The silicone rubber may be vulcanized by organic peroxides such as benzoyl, chlorobenzoyl, di-tert.-butyl, or cymyl peroxide or tert.- butyl perbenzoate, by treatment with radiation such as gamma rays or high-speed electrons, or by a room temperature method as by mixing with an amine or carboxylic acid salt such as tin or lead octoate and with a cross-linking agent such as ortho or polyalkyl silicates or with an SiH-containing siloxane such as methylhydrogensiloxane or as by forming an acetoxy endblocked polysiloxane as described in Specification 862,576. The cured silicone adhesive may be as described in Specification 767,797, 798,667 or 862,576, or in U.S.A. Specification 2,860,083. The adhesive may be coated either on the vulcanized silicone rubber or on the polyvinyl formal foam and the plies held together, with heat and pressure in a mould if necessary, until the adhesive cures.

Filed: 1927-12-20
Abstract: 282,684. Hohenzollern Akt.-Ges. f³r Lokomotivbau. Dec. 21, 1926, [Convention date]. Clutches, friction.-In friction clutches actuated by pneumatic pressure, the air chamber is formed by a tubular corrugated diaphragm N, extending between a dished plate K, attached to the revoluble clutch drum C, and the coned presser-plate J, which slides and rotates freely in a bore of the shaft A, whereon is rigidly secured a hub B. The plate J is guided by spaced bearings 0, P and has notched engagement, with a part H of the drum C. The, expansible tube N serves also as a retracting-spring. Pressure air is admitted through a stationary tube L, formed with a labyrinth packing in an extended bore of the plate K and centred therein,by separate bearings M. Clutch discs D1, D2 are splined respectively to the hub B and drum C, the discs D1 having inserts D3, between which cooling-air circulates centrifugally, this air passing through apertures in the plates K, J to large channels Q formed between T-section ribs R on the hub B, and being expelled through holes S in the drum C.
Patent GB-411177-A (GB)
Title: Improved process of removing water from sodium cyanide solutions
IPC: C01C3/10
Filed: 1932-12-07
Abstract: Sodium cyanide is obtained from solutions thereof by rapidly heating a thin layer of the solution by contact with a hot body having such a temperature above the boiling point of the solution that evaporation to the dry salt is effected in a brief time.  The process is also applicable to drying a moist mass of sodium cyanide or the hydrate NaCN.2H2O since at raised temperature these are converted into solutions of sodium cyanide.  The heated surface may be made of metal, e.g. iron, may have a temperature of 140--300 DEG  C. and may take the form of a revolving drum internally heated by steam.  The concentrated sodium cyanide solution is applied without preheating for example in the form of a spray or drops, or a thin layer of flowing solution.  The dried cyanide adheres to the heated surface in a compact layer and may be scraped off.  The water vapour formed should be removed as quickly as possible.  By working at reduced pressure, the temperature may be correspondingly reduced.

Filed: 1971-07-26
Abstract: 1327995 Screw mixers; de-gassing P PONCET 26 July 1971 [7 Aug 1970] 34905/71 Headings B1C and B1M Mixing. A screw mixer has at least one pair (as shown, two pairs) of conical screws as 1, 2 and 3, 4, the screws of each pair intermeshing and rotating in the same sense, the cores of each screw being of the same conical as the thread, and the pairs rotating in opposed senses. The apparatus shown has an inlet 7, auxiliary inlets 8, 9 and an outlet 10, Fig. 2, shows the upper pair 1, 2 which has a feeding section 5, 6 with thin flat screw threads decreasing in pitch from left to right. Then follow a cylindrical mixing section, a conical section and a reverse pitch cylindrical section all with trapezoidal threads. Screws 1, 2 are co-rotated by a sprocket chain 15 and geared to the lower pair (which is of the same construction without the feeding section, see Fig. 3, not shown) at 16. The mixing sections may have narrow threads and wide grooves (see Figs. 8 and 9, not shown) permitting one of them to be given an additional motion of axial reciprocation (see Fig. 7, not shown) by an eccentric in order to wipe the bottoms of the grooves or the flanks of the threads; by suitable choice of the ratio of rotational speeds of the eccentric and screw wear can be spread round the screw. De-gassing: The screws may be enclosed in a housing under reduced pressure; if the second pair is rotated faster or is of larger diameter than the first, voids will be created in the material, promoting de-gassing.

Abstract: 910,783. Justifying type. INTERNATIONAL PHOTON CORPORATION. Oct. 15, 1959 [April 17, 1959], No. 34996/59. Drawings to Specification. Class 100 (3). [Also in Group XX] A type-composing machine comprises a memory in which a complete line is stored before it is actually composed and counters for counting the length of the line as it is inscribed in the memory and comparing it to the desired justification length, and when an interword space appears in the line after the length of the line has reached a value for which it can be justified, as determined by the counters and comparison circuits, inscribing of the line in the memory is interrupted, the line justified and sent to the composing unit and the interword space cancelled. The machine is controlled from a coded tape and is provided with a storage memory for the length of line and number of interword spaces, and two counters, whereby an electric circuit arrangement, one relay is energized when the line has reached the minimum length for justification, and a second relay is energized when the line has reached within five characters of its maximum length for justification. Furthermore, special signals called " discretionary hyphens " are introduced by the operator at points where words may be broken. (1) Discretionary hyphen signals occurring before the justification zone is reached, and also within the justification zone but before the energization of the second relay are ignored. (2) If an interword space occurs within the zone before the second relay is energized, the inscribing of the line in the memory is interrupted, the line is justified, and the space is cancelled. (3) If either an interword space or a discretionary hyphen occurs after the second relay is energized and within the justification zone, the line is justified, in which case the width of the hyphen is taken into account. (4) If neither an interword space nor a discretionary hyphen occurs within the justification zone, the tape reader is stopped, a relay is energized which increases the maximum increment by which an interword space can be increased, and which conditions the machine for mixed justification by interword spaces and the spaces between characters in a word, and the last characters of the line are erased one by one until an interword space or a discretionary hyphen is reached, when the line is justified with unusually wide spacing. Specification 857,791 is referred to.
