Title: Improvements in or relating to the cooling of vehicle brakes
IPC: F16D65/827
Filed: 1938-11-03
Abstract: 520,510. Actuating air pumps by vehicle motion. BENDIX, Ltd., and IRVING, J. S. Nov. 3, 1938, No. 31817. [Class 8 (i)] [Also in Group XXXIV] Movement of a vehicle chassis relatively to the axles or wheels is utilized to vary the volume of a chamber or to operate a pump arranged to force or draw air through the brake drums to cool the brakes. The cylinder 10 of a double-acting pump is mounted on the chassis 11 and the piston rod 13 is linked to the rear axle casing 12. Inlet and outlet pipes 15, 16 are connected through non- return valves to the upper and lower cylinder chambers. As the chassis rises and falls during travel of the vehicle, air is forced into the brake drum through the pipe 16 connected to the back plate of the brake. A combined water-trap and dust filter 18 is connected to the inlet pipe 15. The valves may be dispensed with, so that the pump alternately draws and forces air through the drums. A single pump may supply air to a reservoir connected to the brake drums of all the wheels. The pump may be mounted on the back-plate, and the piston be connected through linkage to the chassis. The pump may be of the oscillating-vane type. The air may be drawn from the body of the vehicle so that a circulation of air is maintained in it.

Abstract: 818,168. Battery charging systems with variable speed A.C. generators. UNTERNEHMUNGEN DER EISENUND STAHLINDUSTRIE A.G., FUR. Oct. 11, 1957 [Oct. 13, 1956], No. 31899/57. Class 38 (4). A battery charging system wherein a battery 6 is charged over a rectifier 3 by a self-excited alternating current generator 1, the excitation winding 7 of which is fed from the generator output over a rectifier 8 and a saturable choke 12 having two magnetically opposed pre-. magnetizing windings 13, 14 is characterized by the provision of a relay 17 operative to disconnect the battery 6 when the speed of the generator is zero thereby preventing the battery 6 from discharging through the windings 13, 14. The pre-magnetizing winding 13 is fed from the generator output by way of a rectifier 15 the current through the winding 13 being held constant by the provision of a barretter 20, whilst the pre-magnetizing winding 14 is energized in dependence upon the voltage of the battery 6. When the battery is substantially fully charged the effect of the winding 14 approaches that of the winding 13 so that the choke 12 assumes its highly inductive state to reduce the generator excitation and thus the charging current. When the generator 1 is started up the relay 17 is energized to close its contacts 23, 34, but until the generator delivers a voltage sufficient to normally energize the winding 13 the winding 13 is energized from the battery 6 over a blocking half-wave rectifier 30, the values of the resistors 24, 19 being so chosen that when the windings 13, 14 are both being supplied by the battery 6 the winding 13 is predominant. The blocking rectifier 30 is provided to ensure that the winding 14 is not supplied from the rectifier 15 whilst the blocking rectifier 18 prevents the battery from discharging through the relay hold-in resistor 35.
