Title: Improvements in the manufacture of electrical insulating sleevings and braids
IPC: H01B13/06
Filed: 1943-02-17
Abstract: 563,637. Electric cables. TOWNSEND, L. W. E. Feb. 17, 1943, No. 2609. [Class 36] Insulating sleeves or braids for covering electrical conductors are produced in continuous lengths by passing a braid through a singeing apparatus, and then through a concentrated solution of an insulating material composed of an artificial resin or a thermoplastic material. The braid is a woven braid, either hollow or flat, constructed of cotton, silk, artificial silk, viscose, nylon, glass or similar materials. The braid is first singed by passing through a non- luminous flame 2 or a tube heated to at least 500‹ C., and then the braid may be converted into tubular form by means of a ball 3 of greater diameter than the bore of a heated nozzle 4. The braid is then passed through baths 5, 7 containing artificial resin &c. and through electrically heated drying towers 6, 8, finally passing over a pulley 9 and bollard 10. The insulating material is preferably applied as a hot solution thereof containing not less than 20 per cent by weight, and the towers 6, 8 are at such a temperature that all solvent is removed, and, if necessary, the resin fluxed. Further applications may be applied similarly. The braid may be passed through a waterproofing composition such as a solution of rosin, resin, ester gum, varnish, xylol formaldehyde, or glyptal (Registered Trade Mark). The insulating materials may be polyvinyl acetate, polyvinyl chloride, or a copolymer of these two, polystyrol, polythene, cellulose acetate. Varnish resins such as bitumen, aldehyde condensation products, or cumarone may be used. Plasticisers of known form are used, and the solvents may be methyl ethyl ketone, xylol, or acetone. As an example of the process, a viscose braid is passed three times with intermediate drying through a solution of 42 parts by weight of . polyvinyl chloride-acetate copolymer dissolved in .107 parts of a mixture of acetone and methyl ethyl ketone, with the addition of 10 to 20 parts of ethylene glycol mono n-butyl ether mono-phthalate, or tricresyl phosphate; the temperature of the solution being between 15‹ C. and 35‹ C.

Title: Improvements in the production of hydrogen and gases containing hydrogen
IPC: C01B3/52
Filed: 1928-01-31
Abstract: 311,299. Gordon, K., and Imperial Chemical Industries, Ltd. Jan. 31, 1928. Hydrogen.-In freeing hydrogen or gases containing it from carbon dioxide by scrubbing with water or an aqueous solution under pressure the pressure is released from the resultant solution in separate stages or to a limited extent so that a gas richer in hydrogen than that in solution is first obtained. The first gas fraction or fractions may be compressed again to the original pressure and returned to the washing process. Aqueous solutions of substances which increase the solubility of carbon dioxide or decrease the solubility of the other components of the gaseous mixture,. or both, may be used in the scrubbing. The carbon dioxide finally evolved may be used for carbonating ammonia liquor in making ammonium sulphate from gypsum. The scrubbing may be effected at about 200 atmospheres pressure; the first reduction may be to about 25 atmospheres and the final reduction, which may be carried out in a Pelton wheel, may be to 1 atmosphere. Examples are given in the Specification.

Title: Improvements in compressed air brakes for trains, tramcars and other vehicles
IPC: B60T15/46
Filed: 1925-02-03
Abstract: 241,075. Sch³ren, H. Feb. 3, 1925. Fluid-pressure.-In an automatic compressed air brake system, simultaneous application and release of the brakes throughout a train is secured by the provision in the train pipe, near each triple valve, of a cylinder in which works a piston 3 under the action of train pipe pressure, the arrangement being such that the piston cuts off communication between the train pipe and each triple valve as long as there is any appreciable difference in pressure on opposite sides of the piston. When the piston is in its central position passages 4, 4<a> through it are closed by spring- pressed valves 7, 7<a>, the stems of which are preferably coaxial with the cylinder and are guided and supported by members connected with it, and communication between the train pipe and triple valve is established by way of a passage 9 through the piston, a recess 10 in its circumference, and passages 11, 12. If train pipe pressure on one side of the piston is reduced to effect a brake application, the piston is moved from its central position by excess pressure on its other side, thereby cutting off the train pipe from the triple valve, and one or other of the valves 7, 7<a> opens to give free communication between opposite sides of the piston, so that the decrease of pressure is rapidly propagated down the train pipe. When the train pipe pressure has become steady all the pistons 3 are returned to their central position by the springs of the valves 7 or 7a, so that the triple valves throughout the train act simultaneously. Simultaneous release of the brakes is similarly effected. In order to increase the rate of pressure reduction in the train pipe during a brake application, local venting valves 15 may be provided. With the valve shown in the Figure, when the pressure is reduced on the right-hand side of the piston 3, a piston 16 to which the valve 15 is attached is moved to the right against the pressure of a spring 18 to vent the train pipe to the left of the piston 3 through passages 14, 20. A second valve 15 is preferably provided to vent the train pipe to the right of the piston 3 when the pressure on its left hand side is reduced. By means of a three-way cock 21, the triple valve may be conneoted to the train pipe by a passage 19 which is never covered by the piston 3, this arrangement permitting vehicles fitted with the present device to be coupled to vehicles fitted with standard brake equipment. The triple valve shown in the drawing is desuribed in Specifcation 214,703.

Title: Improvements in automatic couplings for railway and like vehicles
IPC: B61G3/16
Filed: 1922-02-03
Abstract: 174,946. National Malleable Castings Co., (Assignees of Willison, J.). Feb. 4,1921, [Convention date]. Couplings, automatic.-In an automatic coupling, for railway vehicles, of the vertical-plane rigid-jaw type described in Specification 9622/12, in which the coupler consists of twin interlocking members locked by a gravity-actuated lock which slides on an incline in a longitudinally extending cavity in each coupler head, the axis of the coupler head and the axis of the lock are arranged at an angle to the line of draught. Each coupler head A, B, Fig. 1, has rigid jaws 2, 3 and a gravity-operated lock 10 which slides, in a cavity in the coupler head which is inclined downwardly and towards the line of draught. In the side elevation of the lock, Fig. 4, a hand-operated shaft 11 is shown, on which is mounted a forked lever 13 engaging a link 12 connected with the lock and enabling the lock to be turned into its set position for coupling. When uncoupling from the locked position, Fig. 1, the shaft 11 is revolved to the left, which carries the lock upwardly and rearwardly along the floor of the cavity and inclined side rib 22 on the wall of the coupler head. On the projections 26, 27, 28 of the lock contacting with the wall 16 of the coupler an inclined rib 17 on the coupler head bears against the bottom of the lock and swings the front edge of the lock inwardly against the inclined ledge 30, Fig. 5, of the coupler head; this tilts the lock and enables the tongue 31 on the lock to pass to the rear of the projection 20 on the coupler head and to enter the groove 32. On releasing the shaft 11 the lock slides downwardly and forwardly with the tongue 31 in the groove 32 and bears against the corresponding face of the lock of the opposing coupler. When the couplers are pulled apart the lock slides forward until the lateral extension 29, shown in the front elevation of the coupler, Fig. 5, strikes the inner edge of the inclined wall 30, the tongue 31 then passes out of the groove 32, and the undersurface of the lock rides over the top of the projection 20 and drops with the tongue 31 in the groove 25, the slot 23 at the same time engaging with the rib 22. The lock then slides forwardly until the projection 20 engages the end of the groove 21 on the underside of the lock. In coupling, the locks 10 contact and are pushed rearwardly in their guides until the jaw 3 of one coupler strikes the buffing face 4 of the other; a relative lateral movement of the coupler heads then occurs, and the locks 10 clear one another and slide down into engagement to lock the jaws 3, 2.
