Abstract: 953,299. Power assisted steering gear. CLARK EQUIPMENT CO. Feb. 11, 1963 [Feb. 14, 1962], No. 5397/63. Heading B7H. In a power steering system for an articulated fork lift truck comprising a reservoir 40 feeding a pump 42 supplying fluid to double-acting fluid cylinders 24, 26 through an open centre control valve 46, orifices 84, 86 restrict fluid flow between the control valve 46 and the cylinders 24, 26, and one-way valves 90, 94 permit fluid to flow directly from the reservoir 40 to the cylinders. By this means undesirable oscillations between the front and rear sections 12, 14 of the truck are damped and vacuum formation in the cylinders 24, 26 is prevented when the pump 42 is inoperative during towing of the truck. The pump 42 is provided with a relief valve 50 and supplies the control valve 46 through a non- return valve 96. The control valve 46 comprises a spool 56 connected to the rear section 14 by a rod 58, and a body 52 connetted by rod 60 to a steering arm 62 actuated by a steering wheel. A spring 64 biases the spool 56 toward a neutral position wherein fluid supplied by the pump 42 through a conduit 48 flows around a groove 67 in the body 52 and grooves 79, 81 in the spool 56 and through bores 83, 85 to grooves 71, 73 communicating with grooves 65, 69 connected with a return conduit 82 to the reservoir 40. Grooves 75, 77 in connection with the bores 83, 85 communicate through conduits 74, 78 with the respective ends of the cylinders 24, 26. When the arm 62 displaces the valve body 52 fluid flow to one conduit 74 or 78 is progressively reduced and communication between the other conduit 78 or 74 and the return conduit 82 is correspondingly restricted. In another embodiment of the control valve 46 screws co-operate with passages in the valve spool 56 to restrict flow to and from the cylinders 24, 26 and the orifices 84, 86 are dispensed with. Specification 839,498 is referred to.

Filed: 1955-02-23
Abstract: 826,463. Gas-blast switches. BRITISH THOMSON-HOUSTON CO. Ltd. Feb. 16, 1956 [Feb. 23, 1955; Nov. 10, 1955], Nos. 5481/55 and 32221/55. Class 38 (5). In an air or gas blast circuit-breaker having a resistance 28 connected by means of a series gap in parallel with the circuit interrupting contacts 11, 14, a chamber 34, within which the electrodes 31, 32 are positioned, is subject to a reduction in pressure in response to the flow of air or gas during opening of the contacts 11, 14 to facilitate breakdown of the series gap. The arrangement shown is that of Specification 762,988 with the addition of an ejector 102 having an inlet port connected by a pipe 100 to the chamber 34, a venturi 103 connected by a pipe 104 to the contact chamber 1 and a discharge port 106 connected by a pipe 107 to the main discharge passage 21 of the circuit-breaker. When the pressure air or gas is applied to the chamber 1 to open the contacts 11, 14, the pressure air or gas flows through the ejector and entrains air from the chamber 34 to reduce the pressure in the chamber 34 substantially below atmospheric pressure to facilitate the breakdown of the gap. When the flow of the blast gas ceases due to an exhaust valve piston 23 closing ports 22 as described in the Specification referred to above, the pressure in the chamber 1 is applied to the chamber 34 to increase the dielectric strength and facilitate interruption of the resistor current. In an alternative construction, Fig. 2 (not shown), the pipe 100 is connected to a double venturi arrangement disposed in the main discharge passage 21. Fig. 1 (Complete) (not shown) illustrates a construction in which the piston 23 is omitted and the chamber 34 is connected to the passage 21 at a throat of Venturi form.
