Title: A sliding spool valve for a power steering system
IPC: B62D5/087
Filed: 1978-08-17
Abstract: A mechanically actuable sliding spool valve has a first valve component movable in response to mechanical actuation and a second valve component movable in relation to the first valve component in response to pressure-medium pressure, whereby the output of the valve corresponds to the sum of the valve component movements. The first component may be a valve rod (17) on which the second component, a sliding valve spool (3), is displaceable through pressure. Alternatively, the first component may be the spool (43) and the second component a lining (44) displaceable in the valve housing (42) or the housing itself which is arranged to be movable. The adjustment of the valve in response to the pressure medium permits a compensation or fine adjustment of the valve setting determined by the steering wheel position to be made. <IMAGE>

Abstract: A uni- or multiphase reverse current converter comprising a bridge circuit of thyristors T1-T6 having a supply voltage terminal and an output voltage terminal, has pairs of said thyristors rendered conductive with the aid of control- signals synchronized with the frequency of the supply voltage and produced by a pulse circuit (not shown) for passing the supply voltage to the output. The safety circuit comprises a capacitor branch C1 coupled with a supply circuit and being disconnectable by a switch 17. The capacitor branch is connected parallel to the arms T4-T6 of the bridge circuit. The switch T7 is controlled by interference pulses produced by a control-circuit U1, the control-circuit being coupled to the pulse circuit in order to block the production of control-signals at the occurrence of interference pulses. The safety circuit comprises a branch R1 connected parallel to the bridge circuit and being switched on and off by a switch T8, T9 and being switched on when the capacitor branch is disconnected by switch T7. There the capacitor branch quenches the conducting one of thyristors T4, T5 and T6 and the other branch then quenches the conducting one of thyristors T1, T2 and T3. <IMAGE>
Patent GB-2039002-A (GB)
Title: A flood control arrangement for dishwashers
IPC: A47L15/42
Filed: 1979-12-14
Abstract: The arrangement includes a sealing plunger 62 disposed in a plunger body member housing 60 installed downstream of a water fill valve 42. The sealing plunger tends to be moved to the sealing position by the line water pressure to shut off inflow to the dishwasher but is blocked from movement to this position whenever the water level is below the flood level by the stem 78 of a float 82 positioned in the dishwasher tub 26. When the water level in the tub approaches the flood level, the float rises in the tub to a position whereat the float stem releases the sealing plunger to allow it to move to the sealing position and shut off further flow to the dishwasher. The float stem either causes the sealing plunger to be tilted off a sealing face or prevents it from moving laterally in the line to the sealing position in order to produce the blocking action. <IMAGE>
