Title: Improvements in and relating to induction voltage regulators
IPC: C21B13/08
Filed: 1928-09-21
Abstract: 297,471. British Thomson-Houston Co., Ltd., (Assignees of West, H. R.) Sept. 23, 1927, [Convention date]. Regulating transformers. - In an induction regulator comprising a primary winding 15 connected in shunt with the circuit to be regulated and arranged in slots in the rotor core 13 and a secondary winding 11 connected in series with the circuit and arranged in slots in the stator core 10, the rotor teeth lying between the magnetic pole teeth on the rotor are shortened to provide increased reluctance in the magnetic circuit. thus reducing the reactance of the windings particularly when the rotor is in positions intermediate the neutral positon and positions giving maximum positive or negative boost. A short-circuited winding 18 is provided on the rotor to provide low reactance in the neutral position. Mechanical support for that portion of the rotor winding lying in slots bounded by short teeth is afforded by wooden or non-magnetic metal, e.g. German silver, strips 22 formed with grooves to permit circulation of oil or other cooling medium. The width of the rotor poles may be made equal to the width of the interpolar sections on the stator core as shown in Fig. 4, or substantially less than interpolar sections on the stator coil as shown in Fig. 2, thus permitting a reduction in the ratio between the ampere-turns of the short-circuited winding and the ampereturns of the secondary winding and consequently making possible the use of conductors of larger section for the primary and secondary windings.

Title: Improvements in vacuum brake apparatus
IPC: B60T13/46
Filed: 1931-10-07
Abstract: 382,403. Fluid-pressure brakes; linkwork. SOC. DES FREINS HOUPLAIN, 37, Boulevard Haussmann, Paris. Oct. 7, 1931, No. 27851. Convention date, Jan. 21. [Class 103 (i).] Vacuum brake apparatus comprises a small piston sliding in a cylinder carried by a larger piston which slides in a fixed cylinder, and a spring-loaded valve controlling communication between the undersides of the two pistons so that the large piston is moved and becomes clutched to the small piston to apply the main braking pressure only after the brakes have been initially applied by the small piston. The large piston 14 sliding in the fixed cylinder 13 carries the cylinder 15 of the small piston 27, the upper ends of both cylinders being open to the auxiliary reservoir 12. The piston 14 normally rests upon a seating 11a so that the central part 17 of its under surface is isolated from the outer part. The cylinder 15 is adapted to connect with the space 18 beneath this outer part through a spring-pressed valve 22 carried by the piston 14. A ball-clutch device for coupling the piston 14 to an extension 29 of the rod 28 of the piston 27 comprises a cage 34 containing balls 36 adapted to wedge between the rod 29 and a conical recess in a piece 31 secured to the cylinder 15. The cage 34 is normally held slightly raised to disengage the balls against the action of a spring 37 by the engagement of a bar 33 secured to the cage with the end of a slot in the cylinder 13. Normally, the reservoir 12 and the space above the pistons 14, 27 is exhausted through the train-pipe connection 4 and ball valve 7, the space beneath the piston 27 is exhausted through passage 19 and the space 18 beneath the piston 14 through the ball valve 41. Air admitted to the train-pipe to apply the brake passes through passage 19 first to the space beneath the piston 27 which is thus lifted and, when the pressure beneath this piston is sufficient to overcome the spring of the valve 22, passes through passage 20 and the valve 22 to the space 18 thus lifting the piston 14 which then becomes clutched by the device 36 to the piston 27. In a modification, the ball-clutch device is disposed in a conical space formed in the underside of the piston 27 and comprises pieces 45, Figs. 3 and 4, held by rings 47 to the rod 28 of the piston between which and a conical part 43 secured to the piston 14, the balls 36 are arranged to wedge. A ledge 49 projecting from the fixed base of the cylinder, normally holds the balls disengaged. The cage containing the ball valve 7, Fig. 1, is secured to a part 6 operable by a lever 9 whereby the cage may be slid within the casing 1 to unseat the valve and thus connect the upper and lower chambers of the brake cylinder to release the brakes on a detached vehicle. The part 6 has a passage 8 by which the passage 2 is connected to the passages 3, 4 past the ball valve for exhausting the upper chamber.
