(4.) An electro-pneumatic controller for electric motors in which the electro-magnetically actuated valves for admitting fluid pressure to the releasing-cylinder are so connected with the armatures of the electro-magnets that when the electro-magnets are energised the releasing-cylinder is exhausted, and when de-energised fluid pressure is admitted to the releasing-cylinder and causes the controller-drums to return to their zero or “off” position, for the purpose specified. (5.) An electro-pneumatic controller, having means operated either pneumatically or electro-pneumatically for cutting off the air-pressure from the operating-cylinder of the controller and for venting such operating-cylinder into the atmosphere whenever the releasing-cylinder of the controller is in communication with the source of fluid under pressure, substantially as and for the purpose specified. (6.) An indicating- and governing-device constructed and operating substantially as described with reference to Figs. 1 to 6 of the drawings. (7.) In an electro-pneumatic controlling-system of the kind described, a safety-valve device which is operated by an electro-magnet connected to the motor circuit and serving when the current to the motors exceeds a predetermined limit to cut off air communication between the controller operating-cylinders and the governing-device, for the purpose specified. (8.) The safety-valve device constructed and operating as described, and shown in Fig. 8 of the drawing. (9.) The means for interrupting the electrical circuit of the magnet of the operating-cylinder of an electro-pneumatic controller, or for directly cutting off air from such cylinder and exhausting any pressure that may be contained therein, substantially as described, and shown in Figs. 11 or 12 of the drawings, for the purpose specified. (10.) In an electro-pneumatic controlling-system for railway-vehicles, means for automatically interrupting the governing circuit of the controller, and thereby opening the power circuit when the brakes are applied, substantially as described. (11.) The means for breaking the power circuit of an electric railway when the brakes are applied, operating as described, and shown in Figs. 14, 15, or 16 of the drawings.
Specification, 12s.; drawings, 3s.)

No. 12884.—17th August, 1900.—THE BRITISH WESTINGHOUSE ELECTRIC AND MANUFACTURING COMPANY, LIMITED, of Westinghouse Building, Norfolk Street, Westminster, England, Manufacturers (assignees of the Hon. Richard Clere Parsons, Director, Reginald Belfield, Electrician, and William Chapman, Electrical Engineer, all of 5, Norfolk Street, Strand, Westminster, England). Improvements relating to electric railways.*

Claims.—(1.) For electric railways operated on the conduit system, a yoke having projecting ribs 4 cast or otherwise formed integral therewith, preferably on each side thereof, surrounding the lower portion of the conduit, substantially as and for the purpose specified. (2.) In an electric railway of the kind described, the connection of the slot rails both to the car rails and to projections 8 formed on the yoke for the purpose of preventing partial closure of the slot, as described with reference to Fig. 1 or to Fig. 4 of the drawings. (3.) In an electric railway operated on the conduit system, means for supporting a conductor in the conduit, comprising a bracket 14 bolted to the yoke, within a box 10 also bolted thereto, said bracket being provided with an orifice in which an insulator 15 is located, being secured by a cap 18 bolted by bolts 19 to the bracket, and an L-shaped piece 16 secured to the insulator by a nut within the cap 18, upon the lower extremity of which the conductor 17 is fastened, substantially as described. (4.) A modification of the supporting-means claimed in claim 3 in which the bracket is replaced by a shelf supported on ledges within the box 10, substantially as described. (5.) For use in conveying current to electric cars operated on the conduit system, a plough which is suspended from the car by rivets or other fastening-pieces of copper or other metal which when the plough meets an obstacle will be easily sheared, and cause the plough to become detached from the car, substantially as described. (6.) For use in conveying current to electric cars operated on the conduit system, a plough supported by pins 34 from a slider 35, whereby it is capable of angular movement, vertical movement, or horizontal movement transversely to the car without becoming dismounted, substantially as described. (7.) A plough in which the contacts 24 are supported on two pairs of horizontal links 26, 27, and a horizontal spring 28 for pressing the contacts outward against the conductor, substantially as described.

Claims.—(1.) The process described for lining casks, barrels, and the like vessels, consisting in the following steps: (a) The admission of sterilised heated air into the vessel; (b) the injection of the lining-material into the still heated vessel; and (c) the admission of compressed air in such quantity as will expand in the vessel, and so reduce the temperature therein as to cause the lining to set or harden, substantially in the manner and for the purposes set forth. (2.) Lining casks, barrels, and the like vessels by first admitting sterilised heated air therein, then injecting the lining-material into the still heated vessel, and subsequently setting the lining by admitting compressed air in such quantity as will expand in the vessel and reduce the temperature therein, substantially as and for the purposes described, and by apparatus such as is shown in the drawings. (3.) Apparatus for lining casks, barrels, and the like vessels, comprising means for supplying air, a furnace for heating the air, a series of distributing-pipes with nozzles thereon, a tank for the lining-material, provided with means for keeping the lining-material fluid, and with means for injecting same through spraying-nozzles into the interior of the vessel, and a compressor for supplying air to the interior of the vessel after the spraying, substantially as described with reference to Fig. 1 of the drawings, and for the purposes stated.
