Title: Process of producing a porous sheet material
Inventor: ROBERTS FRANK SOMERVILLE
IPC: E04B1/74
Filed: 1953-11-16
Abstract: 767,957. Rubber compositions. DURIE & MILLER, Ltd. Oct. 25, 1954 [Nov. 16, 1953], No. 31750/53. Class 70. [Also in Group VIII] A porous sheet material consists of particles of organic granular material linked together by local adhesion to present a large number of intercommunicating cavities open to the atmosphere some of the cavities having a volume which is very much larger than the volume of any of the particles of material. The material may be prepared by foaming a mix comprising a foamable aqueous solution or suspension of an adhesive mix of natural rubber latex or synthetic resin and a granular organic material in the proportion of 2 to 14 parts by volume of granular material to 1 part of total dry rubber or resin content of the solution or suspension, and drying a layer of the foam under such conditions that envelopes enclosing the air bubbles in the mix are destroyed before the granules have an opportunity of settling. In an example a rubber latex mix is prepared by mixing in a mixer 1, Fig. 3, in parts by weight: concentrated rubber latex 130, rubber reclaim dispersion 50, sulphur 2À5, zinc diethyldithiocarbamate 0À75, zinc oxide 5, 5 per cent aqueous sodium alginate solution 100, and 10 per cent aqueous casein solution 25. The mix is fed into a vessel 4, where 200 parts by weight of light red rubber crumb are added, and is then foamed by a stirrer 6. The vessel 4 is tilted to deposit the batch 9 on a backing 8, e.g. of hessian, to be spread by a spreader 10 and passed into a heated drying chamber 11 where it is slowly dried, e.g. at a temperature of 95‹ to 105‹C., in a moist atmosphere. After drying the material is trimmed by knives 13 and wound into a roll 15. In an alternative embodiment the rubber latex mix comprises 58À9 kgs. concentrated rubber latex, 24À95 kgs. black rubber reclaim dispersion, vulcanizing, filling and preserving ingredients, sodium alginate and casein. To this mix is added 60À6 kgs. of granulated cork, and a sheet material is prepared as described above. The backing may, alternatively, comprise cotton scrim, paper, nylon fabric, or impermeable synthetic resin or leather material, or the backing may be omitted from the finished product, the mix being spread on a support such as wire gauze from which it can be stripped when dry. The granular material may also consist of sawdust and the binding material may comprise synthetic rubber latex or a suspension of reclaimed rubber or of synthetic resin such as polyvinyl chloride or acetate. Specification 414,814 is referred to.

Abstract: 670,388. Mechanical couplings for cable sheathing. BRITISH INSULATED CALLENDER'S CABLES, Ltd., BAKER, H. A., and GLICK, D. Dec. 12, 1950 [Dec. 12, 1949], No. 31811/49. Class 38 (i). A sealing termination for a metal-sheathed cable comprises a tubular metal body fitting at one end over the end of the cable sheath 8, the wall of the body at that end having internal projections 3 and being radially cut at 5 and expanded to form an outwardly divergent cable entry 1. A nut 6 engages external threads 4 on the entry 1 and is adapted to contract the entry to force the projections 3 into the cable sheath by being moved forcibly towards the end at which the cable enters the termination, having been threaded on to the entry prior to its expansion. The other end of the tubular body forms a sealing chamber 2 into which compound is introduced.

Abstract: 1,129,713. Luggage handle. C. W. CHENEY & SON Ltd. 3 July, 1967 [19 July, 1966], No. 32271/66. Heading A4G. Rectangular wire loops 15 with arcuate side limbs moulded into a plastics luggage handle 10 connect the handle to mountings 13 fixed to a suitcase by integral rivets 20. When the handle is lifted the end part 40 of loops 15 runs along a curved guide slot between the inside surface 22 of the mounting and upper surface 35 of a resilient block 30 of synthetic rubber or plastics material between and below the side limbs of the loop 15 held in position by end wall 32, lug 29 and inwardly projecting side walls 33 of the mounting. The side limbs of the loop emerge from slots 27 until the end part 40 contacts lug 29. At the same time, the ends 11, (12) of the handle 10 move closer together, deforming its material whose resilience provides a restoring force to return the handle flat against the case when the handle it released. If the dimensions of the guide slot are slightly smaller than those of the loop, the resilience of the block material prevents free play and rattle of the handle.

Abstract: 814,380. Jet propulsion plant; gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Nov. 2, 1955 [Nov. 10, 1954], No. 32604/54. Class 110 (3). In a jet propulsion plant, the compressor is driven by the tangential discharge of highvelocity gas through nozzles mounted at the circumference of the compressor rotor. The gas is produced by an oxidant and a fuel in a combustion chamber and is passed radially outwards to the nozzles from which it flows to a secondary combustion chamber and is discharged, as a propulsive jet, through a variable area outlet. In a second embodiment, not shown, the compressor is driven both by the nozzles and by a turbine driven by the nozzle discharge gases. As shown, the gases formed in chamber 16 by the combination of fuel and oxidant flow radially outwards through passages 10 in the rotor 9 to the discharge nozzles 23 set at an angle to the rotor plane. 9 is caused to rotate by the tangential component of the discharge and thus drives the compressor 8 set in the air intake 1. The nozzle discharge gases when mixed with the compressed air stream continue to burn in chamber 27. Release is effected by nozzles 29 through which fuel or oxidant may be injected. The outlet area is adjustable by members 31. Preheating of the fuel may be effected by its passage through a heat exchanger to which heat is supplied by a fluid which flows through a circuit adjacent the aircraft surface and thus absorbs heat generated by air friction. Specifications 749,009 and 808,833 are referred to.

A transparent or metallic guard 10 for a hand or other press is mounted with lost motion on a block 19 secured to the press ram (not shown) and is linked to a pawl member 20 pivoted on the block 19 so that should the descent of the guard be obstructed the relative movement between the guard 10 and block 19 swings the pawl 20 about its pivot 21 into engagement with fixed ratchet teeth 34, thereby stopping the descent of the press ram. The guard 10 is carried by a stem 15 slidable in the block 19, the stem 15 and pawl 20 having fixed thereto respective arms 28, 22 interconnected by a link 26. During unobstructed descent the weight of the guard holds the rectangular pawl member 20 against a surface 37 of the block 19 so that it is clear of the teeth 34.

[Class 40 (iv).] An electric hearing- apparatus for the' deaf comprises a rubber casing A which is shaped to fit into the ear and has fixedly mounted therein a pot magnet 3 having a central sleeve 6 surrounded by a coil 4. A second pot magnet 2 is supported on the circumference of the magnet 3 by a rubber ring 7 and carries an armature core 5 surrounded by a coil 1 and .supported in the sleeve 6 by a further rubber ring 71. The magnet 2 also carries a rubber rod 8 adapted to bear at its outer end against the tympanum of the ear. The coils 1, 4 are connected in circuit with a microphone and battery in such a way that the magnets 2, 3 tend to repel one another and the core 5 tends to be expelled from the sleeve 6, movement of the magnet 2 relatively to magnet 3 being restrained by the tubes 7, 7<1> which provide the necessary restoring force. As shown in Fig. 3, the rod 8 terminates in a spoon 9, the conicity of the end 10 being smaller than that of the natural tympanum. A steel wire 11 embedded in the rod enables it to be bent to an angular position adapted to the auditory passage. In the event of the. tympanum and auditory ossicles having been removed by operation, the rod 8 is formed with a hollow spherical end adapted to contact with the osseous labyrinth wall. The Specification as open to inspection under Sect. 91 comprises also a modification, Fig. 3 (Cancelled), in which the rod 8 is actuated by a reed armature 17. This subject-matter does not appear in the Specification as accepted.
