Title: Power supply apparatus
IPC: H02M3/335
Filed: 1981-01-02
Abstract: A forward converter circuit (Figure 1) is provided with a transformer reset sensing circuit (Figure 2) whereby base drive to the switching transistor TR1 is inhibited until after reset of the transformer T1. The reset sensing circuit includes a sensing winding T1d provided on the transformer for sensing the waveform at the primary winding T1a, a comparator IC1 and diodes D3, D4, connected in such a way that one input of the comparator is high when the waveform changes in one direction, and the other input of the comparator is high when the waveform changes in the other direction. The output of the comparator inhibits switching of the transistor before reset and thus allows the use of a maximum switching duty cycle of 50% without risk of transformer saturation. <IMAGE>

Title: Valve means for dispensing gas
IPC: G05D16/06
Filed: 1981-04-09
Abstract: Valve means for the withdrawal of gas, at a low pressure suitable for a domestic appliance from a high- pressure vessel (11) includes a main closure valve (13) for connection to the vessel (11). The valve (13) has a displaceable closure element (22) which is actuated by a tappet (81) which is connected to the spring- loaded diaphragm (76) of an attached reducing valve (14). When the pressure of gas at the outlet side falls, the diaphragm (76) deforms, thus moving the tappet (81) to cause displacement of the closure element (22) to open the main valve (13). The reducing valve (14) may be installed at the lower end (92) of a receiving chute (91), in which a gas cylinder (11) with the main valve (13) attached is slidable downwards, to cause engagement of the main (13) and reducing (14) valves by means of a simple push-in connection. <IMAGE>

Title: Wheeled vehicle fitted with a brake
Inventor: PLATT NIGEL TERRY WALTER
IPC: B62B5/04
Filed: 1981-12-07
Abstract: A wheeled vehicle, particularly a wheelchair, is fitted with a brake comprising a disc 1 eccentrically mounted on a spindle 2 forming a cam to turn in the plane of rotation of the wheel, so that when the cam is pushed into contact with the circumference 10 of an adjacent wheel of the vehicle (position A or position B) it permits the wheel to rotate in one direction by dragging thereon but prevents rotation in the other direction by creating a jam between the cam and the circumference of the wheel. When the cam 1 is held in a neutral position (C), it is out of contact with the wheel which is thus free to rotate in both directions. The cam 1 is releasably held in the neutral position by the engagement of a ball (3) with a dimple in the floor of a groove in spindle 2 (see Figs. 2, 3). <IMAGE>
