Filed: 1942-07-22
Abstract: 554,436. Safety devices for road &c. vehicles. PEYMAN, A. W. D. July 22, No. 11135. [Class 103(ii)] [Also in Group XL] An automatic safety device for road and railway vehicles comprises an exhauster or vacuum pump y, Fig. 2, one or more vacuum cylinders x controlled by a valve s for operating a brake or fender guard or both these, and photo-electric circuits for determining the position of the valve in dependence on the presence of an obstruction in front of the vehicle. The photo-electric circuits include a lamp e, Fig. 1, focussed to a point ahead of the vehicle, say 40 feet, by means of a parabolic mirror e<SP>1</SP> and a lens e<SP>2</SP>. An infra-red screen e<SP>3</SP> may be provided. A photoelectric cell d is adapted to receive the light reflected by an obstruction at that distance and is connected through a speedometer controlled switch c to an amplifier f, the circuits of which include a relay g, g<SP>1</SP>, g<SP>2</SP>, a triple switch a, an engine ignition coil b, and a device l for converting a low voltage current from a battery k into a high voltage current. The battery k serves to heat the filament of the amplifier f, and to supply anode voltage thereto, and is also connected to the photo-electric cell through a potentiometer m. The amplifier circuits are switched on simultaneously by the three arms of the switch a. The lamp e and the engine ignition coil b are thereby switched in, but the photo-electric cell circuit remains open until closed by the speedometer controlled switch c when the vehicle has speeded up above a predetermined speed. If then obstruction appears in front of the vehicle and affects photo-electric cell d, relay g switches a coil h in and cuts off engine ignition coil b. The valve s, Fig. 2, is operated by the core of the solenoid and the vacuum cylinder or cylinders x operate brakes or a fender or both. The valve s is locked in operated position by a catch s<SP>1</SP> adapted to be released by a control s<SP>3</SP> operated by the driver when the emergency has passed. A suitable expansible fender comprises a number of bars interconnected by a collapsable mechanism of crossed link 5, Fig. 3 (not shown).

Title: Improvements in or relating to rotary pumps of the gearwheel type
IPC: F04C11/00
Filed: 1952-05-02
Abstract: 730,020. Gear pumps; centrifugal pumps. DRYSDALE & CO., Ltd., and YOUNG, J. May 4, 1953 [May 2, 1952], No. 1I170/52. Classes 110 (1) and 110 (2). A two-stage pump comprises pairs of gears 2, 4 and 6, 7, the driving gears 2, 6 being keyed to a shaft 3, and the other gears 4, 7 being mounted on separate auxiliary shafts 5, 8, the axes of which lie on opposite sides of the axis of the shaft 3. A centrifugal pump 20 may suck fluid from a suction pipe 15 and supply a chamber leading to the inlet of the first pump 2, 4. The discharges from the pump stages are on opposite sides of the casing, this helping to balance the loads on the shaft bearings and relieving the load on a centre bearing 3<SP>1</SP>. Fig. 5 shows a valve 12 which regulates the pressure differences over the pump stages, so that the pressure rise over each stage is approximately the same. A port 14 connects with the pump suction 15, a port 16 with the final delivery and a port 18 to a chamber between the pump stages. The area of the top of the valve 12 is twice that of the effective area on the underside of the valve. With equal pressures developed by the pump stages, the valve closes the ports, but should the first-stage delivery rise unduly, the valve 12 moves to open the relief port 14. Should a high pressure be developed in the second stage, the port 18 is opened and allows excess pressure liquid to escape to the suction of the second stage.
