Patent GB-410793-A (GB)
Title: Improvements in or relating to the manufacture of rubber compositions
IPC: C08L7/00
Filed: 1932-11-23
Abstract: Powder-like compositions are prepared from aqueous dispersions of rubber and the like such as those described in Specifications 219,635 and 290,313, [both in Class 70], by coagulating the dispersions in any of the manners described in Specifications 338,975, [Class 70], 373,262, or 379,311, removing all or most of the contained water and converting the dried product into a powder.  The powder-like compositions may be mixed with granular fibrous, or divided materials such as leather fibre, wood flour, cotton flock, naturally short cellulose fibres or alternatively or additionally with mineral powders such as whiting or sand.  These additions may be made in two ways either by admixing these materials direct with the dry powder-like compositions, or by admixing them with the flocculent rubber precipitates before drying has taken place, and then drying the composition so formed. The products of this invention are for use as moulding powders. They possess the advantage of a short moulding time, and the consequent ability to use bright colours.  The preferred method of preparing flocculent precipitates is according to the process described in Specification 373,262.  If the precipitate is obtained in a short paste-like condition consolidation can be facilitated by treating the precipitate with a rubber solvent which may be mixed with a liquid miscible with both the rubber solvent employed and with water, such as alcohol.  Specifications 404,665, 405,956 and 410,794, also are referred to.

Title: Process and device for interrupting heavy electric currents
IPC: H02M1/30
Filed: 1935-11-29
Abstract: 468,140. Conducting-liquid switches. WANGEMANN, P. Nov. 29,1935, No. 33131. [Class 38 (v)] A process for the continuous sparkless interruption of heavy currents comprises the bridging by an electrolytic jet of the space between two electrodes of opposite sign, one of these three elements being moved continuously. The process avoids arcing by avoiding the formation of metal vapours at the cathode spot and, for this purpose, the cathode itself is arranged to be always covered by electrolyte. In Fig. 3, a pair of nozzles 1 forming cathodes are rotated by a synchronous motor 14 to suck electrolyte from a sump 4 forming one pole of the circuit, and project it onto the anodes 2 in turn, to form a polyphase rectifier. To avoid any break in passing from one phase to another, the jets are arranged momentarily to bridge two adjacent ones. In Figs. 4, 5, the electrodes 2 are wedge-shaped in cross-section and a number of them are arranged concentrically, with spaces provided at 18 to separate them into phases. The pump rotor 16 carries the nozzle cathodes 1 which are wide enough to bridge gaps 18 for the purpose stated above. The rotor 16 can be raised and lowered to vary the jet-thickness. Where the rectifier is to serve at the same time as a starter, the anodes 2 are tapered radially inwards at 2<1> and the jets arranged to move gradually up the taper until they engage the anodes proper for normal operation. The electrolyte is maintained at a constant temperature a few degrees below 100‹ C., an adjustable indicating jacket 25 being provided for this purpose. Air-inlets 23 and vents 24 are provided.

As shown in Fig. 1 the lever 3 pivoted in a bracket 1 on the floor board 2 is connected at one end by a rod 5 to the carburetter of the vehicle engine so that upward movement of the rod opens the throttle and also at this end of the lever is arranged the adjustable spring 11 of sufficient strength to support the driver's foot. At the other end of the lever 3 are rollers 7 arranged in a V to accommodate the heel of the driver's foot and a lug 8 which is adapted to engage a button 9 of a starter switch 10 on pivotal movement of the lever. The brake actuating lever 12 carries the foot plate 13 which is forked at the lower end to fit over the lever 3. The arrangement is such that as the brake is applied by forward movement of the foot, the spring 11 takes over control of the lever 3 to reduce the throttle opening. In a modified structure shown in Fig. 4, a plate 26 secured to the brake lever 25 has slidably mounted thereon the foot plate 29 having down-turned guiding flanges 30. The plate 26 has a recess 28 serving as a stop for the sliding movement of the foot plate 29, the recess 28 being engageable by a bracket 31 carrying a roller 33. The roller 33 having guiding flanges engages a cam surface 35 of the throttle lever 17 having the heel rest 20. When the brakes are applied by movement of the lever 25 the foot plate slides upwardly and the roller 33 engaging the upper part of the cam surface 35 depresses the front end of the lever 17 to reduce the fuel supplied to the engine.
