Title: Improvements in or relating to the control of battery-operated electric vehicles
Inventor: KENDON SYDNEY PETER
IPC: B60L11/18
Filed: 1957-05-23
Abstract: 840,219. Control of D.C. motors; controllers. VENNER Ltd. Aug. 5, 1958 [May 23, 1957] No. 16429/57. Class 38 (3). A vehicle is started by closing main switch 4 and setting reversing switch 5 for " forward " or " reverse " as required, an accelerator pedal 18 being depressed to displace a cam-carrier 17 and energize contactors 12-9 in sequence. Current is supplied from battery 3 to a compound-wound driving-motor 1, and, as the pedalmovement continues, progressive stepwise reduction of armature resistance 6 is effected until full motor-speed is reached. Further depression of the pedal 18 causes abutment 19 to engage rod 20 so that contacts 30, 31, engage contacts 26a, 25a, on block 22. A servo-motor 27 thereby drives worm-wheel 35 for increasing the ratio of an infinitely-variable change-speed gear 2 through which the motor 1 is coupled to the rear wheels of the vehicle, and, at the same time, the contact-block 22 is moved in a direction which tends to disengage the contacts 26a, 25a from the contacts 30, 31. Thus, the adjustment of the gear 2 only continues so long as the accelerator pedal is being depressed, and, when the pedal is held stationary, the supply of current to the servomotor is interrupted. Release of the pedal 18 allows return movement of the rod 20 so that contacts 30, 31 engage contacts 26b, 25b, with consequent reversal of the servomotor and progressive reduction in the ratio of the gear 2. The contact block 22 again follows-up the movement of rod 20 and the servomotor is deenergized when movement of the rod ceases. The maximum movement of the block 22 is determined by limit switches 28, 29. Complete release of the accelerator pedal adjusts the gear 2 to its lowest ratio and de-energizes the driving-motor. On steep descents, the road wheels may drive the main motor to provide regenerative braking.

[Class 110 (i).] Pumping machines and apparatus.-A rotary pump for the circulation of mercury is driven by an electric motor, the rotor windings of which are formed by the mercury flowing through the rotor. A cylinder 6 joins the suction pipe 9 and the delivery pipe 10, and houses the rotor 1 which is common to the pump and the driving induction motor. Helical channels 2 are formed, for instance by milling, in the periphery of the rotor, and, if desired, the channels are closed by a tube 3 which surrounds the rotor. The motor stator 7 is arranged round the cylinder 6 and has its windings in grooves 8. When the rotor is flooded with mercury and current is supplied to the stator, the mercury in the channels 2 forms a squirrel-cage winding and the consequent rotation causes a flow of mercury from the pipe 9 to the pipe 10. The pressure of the mercury may be utilized to ensure automatic centring of the rotor, and a piston may be added to assist in balancing the axial magnetic thrust. The rotor of the motor and the rotor of the pump may form two distinct elements.

Abstract: 797,713. Coating apparatus. UNITED STATES STEEL CORPORATION. May 31, 1956, No. 16913/56. Class 140. A thin controllable film of lubricant is deposited on a metallic strip by passing the strip centrally between spaced-apart electrodes extending transversely thereof and electrically interconnected at their ends to form a loop, impressing a high D.C. potential across said loop and strip, dispersing lubricant in a steam of gas, and introducing the dispersed lubricant out of contact with the electrodes into the zone of maximum electrostatic intensity in the space between the strip and the transversely extending electrodes. Oils such as palm oil may be used as lubricants. As shown, the strip 2 passes round deflector roll 4 and into chamber 6 which consists of a steel outer shell 10 and an inner shell 12 of, for example, a phenolic resin insulating material. Within the shell 12, one on either side of strip 2, are a pair of metal grid frames of inverted U-shape, supported by and electrically insulated from the outer shell 10. U-shaped steel frames 14 each carry one or more vertically spaced wires 18 strung between the frame legs and opposed legs of the frames are electrically connected by metal bars 20. A high potential D.C. source 22 is connected between the frames 14 and the strip through conductor-deflector roll 8 mounted on the shell. Roll 8 can be provided with a collector ring and connected directly to the source. Spray heads 30 are connected to atomizers 32 dipping in oil reservoirs 36 made of glass and located outside chamber 6. The connecting pipes and spray heads are of non-conducting phenolic resin material. Heads 30 contain a series of outlets 38 aligned along the length of the heads. Atomization is assisted by heating lamps 46 focused on reservoirs 36 and may be varied by regulating the atomizing gas pressure. Oiling may be conducted as a separate operation or the apparatus may be incorporated in existing strip processing lines.
