Abstract: 994,293. Valves. A. GINOBBI. Nov. 4, 1963 [Dec. 28, 1962], No. 43415/63. Heading F2V. A hydrostatically actuated valve for emptying a liquid container has a cylindrical body 1 with a lower part 1<SP>1</SP> of a lesser diameter to provide a chamber for a piston 6. The piston is lifted by fluid under pressure admitted to the chamber through a tube 8 provided with a hand-controlled valve (not shown), to raise a valve 3 from a conical seat 12, discharge from the container taking place through a lateral aperture 5. Holes in the piston and in a rubber packing are arranged in offset relationship to holes in a sleeve 2 permit the return of the piston to its original position after the handcontrolled valve has been closed. The fluid for actuating the piston may be drawn from the container or from a separate tank.

Title: Apparatus and method for rapid cyclic filtration of contaminants from liquids
IPC: B01D29/00
Filed: 1974-10-15
Abstract: 1489067 Filtering method and apparatus WIX INTERNATIONAL CORP 15 Oct 1974 44694/74 Heading B1D A slurry in chamber 1 (Fig. 2) is thickened using an immersed filter 3 which is subjected to repeated cycles wherein liquid is first drawn through the filter and delivered to chamber 8 for one period after which the filter is backwashed with filtrate for a second period, the periods lasting between 0.0001 and 1.0 seconds and the ratio of the one period to the second period being between 1:1 and 15:1, typically 3:1. This ensures that the filter remains clean and provides a net flow of filtrate approaching that of pure liquid through a clean filter. The cycle is achieved using two rotary valves 15, 16 and either one rotary pump 14 or two rotary pumps (Fig. 1, not shown). Figs. 4. 5, 6, 22 and 23 (not shown) illustrate circuits basically like Figs. 1 and 2 but with by-pass lines which allow the pumps to run continuously without cavitation or pressure surges as the valves rotate. Mixing circuits (47-49) stir the slurry, and there are constant flows of fresh slurry into and thickened slurry out of chamber 1. The valves 15 16 are two-way rotary sleeve valves, with two inlets (or outlets) 58, 65 in the side of the cylindrical housing and one outlet (or inlet) 56 either in the side (Fig. 17) or at one end (Figs. 30-34 not shown). Valve sleeve 126 rotates with shaft S and has an aperture 133 of 90‹ arc, which coincides with inlet 65, out of phase with aperture 131 of 270‹ are aligned with inlet 58. Apertures 136 always connect the sleeve interior with outlet 56. Two such valves may be axially aligned with their respective sleeves connected by a common shaft S to an electric drive motor, or they may be located side-by-side and geared together (Fig. 22). Filter constructions are illustrated in Figs. 3, 7-15 and 24-28 (not shown). All comprise a downwardly directed nozzle of uniform or tapered bore whose narrowest cross-section may be 0.8 to 2 times the open area of the filter medium. The filter medium bridges an annular gasket 99 which is bolted between support rings 95 and 98 on a third ring 89. In Fig. 7 this ring assembly is clamped to nozzle 78 by bolts 104, while in Fig. 8, ring 89 is screwed on to the nozzle. Fig. 3 represents a simpler filter with the medium clamped directly between threaded rings. The filter medium 100 in gasket 99 may comprise a single layer of stainless steel woven mesh of 37Á pore size, but in other embodiments this mesh is laminated with various supporting structures. In Fig. 10 mesh 111 is sandwiched between coarser weave stainless steel discs 109, 110 and discs 107, 107 of nyloncoated expanded metal. Support rings 95 and 98 may be bridged by cruciform ribs to support the medium further. In Figs. 24 to 28, stainless steel discs of plain or Dutch twilled weave and 20, 37 or 40 Á pore size are laminated between various woven or perforate sheets to which they are bonded metallurgically or with epoxy resin.

Abstract: 1,012,604. Aircraft undercarriages, DOWTY ROTOL Ltd. Dec. 3, 1963 [Dec. 3, 1962; Feb. 27, 1963], Nos. 45643/62 and 7915/63. Heading B7G. An aircraft undercarriage comprises two shock absorbers 23 and 28 mounted in series, one shock absorber being adapted to operate as a jack to alter the height of the aircraft in relation to the ground. As shown, for normal landing most of the energy is absorbed by shock absorber 23 any excess energy being absorbed by shock absorber 28. Under excess energy conditions piston 27 is moved upwardly, compressing a fluid in chambers 34, this fluid reacts on a separator piston 31 which compresses air in chamber 33. The energy thus stored can be re-applied to shock absorber 28 for automatic recuperation. When absorber 28 is used as a jack for lowering the aircraft, solenoid valve 35 is operated such that fluid in chamber 34 is allowed to flow via line 43 orifice 46, valve 39, line 44, valve 35 and line 45 to a reservoir (not shown). To allow the flow through valve 39, fluid under pressure derived from the undercarriage retraction hydraulic system (not shown) flows through line 36, reducing valve 40 and line 37 to move member 42 to the left. For raising the aircraft to its normal taxying position, fluid is caused to pass back from the reservoir into the shock absorber 28 to displace piston 27 for extension of the shock absorber, thereby lengthening the undercarriage to its original condition.

Heading F1R [Also in Division F2] A one-way valve in a hydraulic rock hoisting system in which the rock is mixed with water and fed from a reservoir 10 into the cylinder of a hydraulic ram via an outlet 32, comprises a pivoted closure member 16 with a chamber 27 whose buoyancy can be varied by filling with air and water via flexible pipes 28 and 30, respectively, and a seat 14 against which the member 16 seals when it becomes buoyant. In operation water is fed into a replaceable inlet pipe 20, and air is fed into the chamber 27 so that the valve is closed by its buoyancy, and the pressure of the ram completing its displacement stroke. Shortly before the ram retracts, water is fed to the chamber 27, to cause it to be opened by the reducing buoyancy and the pressure differential between the inlet 20 and outlet 32, to connect the contents of the reservoir with the ram. When the contents are displaced from the ram via an outlet conduit, pressure is applied to the outlet 32, and air is supplied to the chamber 27 to close the valve and complete the cycle. Simultaneously with the valve closing, high pressure water is supplied to the seat 14 via a ring of passages 22 to clean the seat.
