Title: Improvements in and relating to electro-pneumatic braking apparatus
IPC: B60T13/66
Filed: 1934-02-27
Abstract: 434,131. Fluidpressure brakes. BROWN, D. F., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Feb. 27, 1934, No. 6316. [Class 103 (i)] Electro-pneumatic brakes for railways are applied by fluid-pressure under the control of electric valves on each vehicle controlled by fluid pressure controlled by a driver's valve of the self-lapping type. Each vehicle carries a brake cylinder 1 supplied from an operating reservoir 2 by means of electro-pneumatic application and release valves 13, 16, controlled by wires 9, 10, 11 running through the train. The wires are controlled by the self-lapping driver's valves 4a and a piston 24 fluid below which is supplied by the control device 4a from the reservoir 2 to cause application, or is released to cause release of the brakes and fluid above which is supplied from or released in accordance with brake cylinder pressure in order to reclose the valves to lap position and maintain a definite pressure in accordance with the movement of the driver's valve 4a. The control device 4a comprises a self-lapping valve for supplying fluid to the piston 24, at a pressure corresponding to the position of the driver's handle. The valves 13, 16 are normally energized and the upward movement of the piston 24 on brake application breaks the circuit of the valves 13 by means of contact 32, the circuit of the release valves 16 is broken by the disconnection of contacts 19, 21 by movement of the driver's valve 4a. Brake cylinder pressure depresses the piston 24 to re-make the circuit for the release valves, to give lap position. In release the piston 24 falls to make circuit by a contact 40 for the release valves and rises again when brake cylinder pressure has fallen the desired amount. In emergency position of the driver's valve 4a contacts 20, 21 are disconnected and both applications and release valves are de-energized to open the former and close the latter to supply maximum pressure to the brake cylinder independently of the action of the piston 24. The motor vehicle of the train is provided with a driver's valve 4a at each end one of which is placed in inoperative position and the handle removed and placed on the switch box 12, whereupon the contacts in the switch box occupy the position shown in the right-hand switch box and maintain continuity of the train wires. To ensure brake application when a train wire brakes, a switch 43 is provided, adapted to open the release train wire 10. A switch 44 is adapted to be operated by a passenger or guard to apply the brakes. Electro-pneumatic switches in the main reservoir pipe 6 break the circuit of the train wires to apply the brakes if pressure in this pipe fails. Combined cock and switch 52 is used to release the brakes on individual vehicles. Fluid-pressure may be supplied direct to the brake cylinder of the motor vehicle from the motor vehicle. Also this brake cylinder may be replaced by a chamber for the purpose of the electrical control.

Abstract: 409,485. Master control of motors. WOOD, F., and SADLER, G. V., c/o Vaughan Crane Co., Openshaw, Manchester. March 3, 1933, No. 6448. [Class 38 (iii).] The brush-gear of an A.C. commutator motor A is operated by a pilot motor B, and both motors are under the control of a master controller D for forward and reverse operation of the main motor at any desired speed, limit switches E, driven by the pilot motor B, being provided to prevent over-running in either direction. Operation of the controller D successively starts up the main and pilot motors, and speeds of the main motor intermediate the slow and full speeds are obtained by returning the controller to stop the pilot motor before the main motor brush-gear has reached the full speed position. The pilot motor is automatically restarted to bring the brush-gear back to the slow speed position when the controller is returned to stop the main motor. The limit switches may be of the drum type, and the controller may control the forward and reverse operation of the main motor by means of interlocked contactors. The pilot motor drives the brush gear and limit switches through worm gearing and pinions.

Title: Improvements in or relating to materials for producing visual records
IPC: B41M5/132
Filed: 1946-03-01
Abstract: In the manufacture of material for producing visual records, a coating composition is prepared by thoroughly mixing with an aqueous solution of a dryable binder, particles of different solid reactant substances, one being an organic substance (especially an aromatic amine) and the other an inorganic substance (especially a clay), the two substances having such characteristics that a distinctive colouration is produced by mutual contact between them.  Preferably the two reactant substances are dispersed in separate quantities of the binder in solution (in the case of the organic substance advantageously by precipitating it in the said solution) and the two dispersions are then mixed, but it is also possible to disperse the two substances in the same solution, provided that they are added separately and the first stirred in before the second is added, and that care is taken in the mixing to avoid rendering ineffective the protective influence of the solution.  In an example, a solution of malachite green lactone in dilute hydrochloric acid is added to an aqueous solution of methyl cellulose containing sufficient ammonia to neutralize the acid and precipitate the malachite green lactone, and the resulting dispersion is added to a dispersion prepared by adding a slurry of kaolin in water, containing a dispersing agent such as sodium metaphosphate, to an aqueous solution of methyl cellulose.  In further examples the methyl cellulose is replaced by casein and the malachite green lactone by 3 : 3-bis-(p-hydroxy-, amino-, ethylamino- or diethylamino-phenyl)-phthalide, the colourless base or the colourless carbinol base of Rhodamine B, fluorescein or its diacetate, tetrabromophenolsulphonephthalein, tetrabromophenolphthalein, the colourless carbinol base of malachite green or of pararosaniline, the imino anhydride of pararosaniline base, Michler's hydrol or its methyl ether, di- or tri - (p - dimethylamino) - triphenylmethane, anisylidenecinnamylideneacetone or cinnamylideneacetophenone. Other suitable binders are starch, gelatine, polyvinyl alcohol, hydroxyethyl cellulose, animal glue and water-soluble gums such as gum arabic, whilst additional inorganic reactant substances specified are aluminium oxide and phosphate, bentonite, calcium chloride, fluoride, carbonate, oxide and sulphate, magnesium carbonate, silicon dioxide and zinc sulphide. Specifications 546,749 and 628,960, [both in Group VIII], are referred to.
