Title: Hydraulic motor control valve
IPC: B62D5/087
Filed: 1963-03-20
Abstract: 964,540. Power steering. CLARK EQUIPMENT CO. March 20, 1963 [March 27, 1962], No. 11028/63. Heading B7H. [Also in Division F2] The control valve 12 (Fig. 1) of a power steering system includes at each end of the valve spool 52 chambers 136, 140 communicating in the neutral position of the valve with fluid inlet ports 106, 110 by way of grooves 138, 142 extending partially across the adjacent lands 122, 126 on the valve spool 52. After an initial displacement of the spool 52 in either direction communication between one groove 138, 142 and the associated inlet port 106, 110 is cut-off whereupon fluid contained in the adjacent chamber 136 or 140 can escape only through a small clearance surrounding the land 122 or 126. The chambers 136, 140 thereby act as dashpots which damp movement of the spool to prevent " overshooting " of the valve and oscillation of the steering system. The Pitman arm (not shown) of a worm and sector steering gear is connected to a drag link 88 which effects displacement of the spool 52 by means of a ball joint 16 to control fluid flow through ports 114, 118 and passages 38, 40 to a double-acting fluid actuator 14. A ballvalve 144 normally held closed by fluid supplied through the inlet port 106 allows transfer of fluid between opposite ends of the actuator 14 to permit manual steering upon fluid pressure failure. Fig. 9 shows a steering system wherein a modified control valve 160 controls fluid flow to the actuators 306 of steerable wheels 284. The valve 160 (Fig. 8), includes a spool 198 displaced by pistons 274, 278 actuated by a positive displacement pump 336 connected to a steering wheel 334. Lands 202, 206 on the spool 198 prevent flow to and from the actuators 306 through ports 186, 188 when the spool is in the neutral position, fluid flow between inlet ports 178, 182 and an outlet port 184 being permitted through bores 220, 222 in the spool. Follow-up actuators 292 (Fig. 9), equalize the pressure on the pistons 274, 278 to restore the spool 198 to the neutral position upon completion of a steering movement. A pump 318 supplies fluid from a reservoir 320 to the valve 160, and the return conduit 324 supplies make-up fluid to the valve actuating circuit through one-way valves 350, 352, excessive pressure in the actuating circuit being relieved by one-way valves 354, 356. A valve according to the invention may be used in a power steering system for pivoting the frame sections of an articulated vehicle. Specification 824,611 is referred to.

Title: Improvements in or relating to laminates of lignin-cellulose comprising a carrier and a synthetic resin cover
IPC: B27N3/20
Filed: 1955-04-19
Abstract: <PICT:0807090/III/1> A process for the manufacture of laminates having a lignin-cellulose containing carrier plate, e.g. of wood, veneer or hard fibre, of predetermined moisture content and a thermosetting resin layer comprises heating and simultaneously compressing the carrier plate and its resin layer, the moisture content of the carrier plate being maintained at a predetermined value by heating the press platen which is in contact with the synthetic resin layer to be hardened while the carrier plate is maintained at a substantially lower temperature.  The synthetic resin may be a phenolic urea or a melamine resin and may be applied by spraying or may be applied as a film having organic or inorganic fibres, preferably dyed or printed, as a carrier and impregnated with the synthetic resin.  The term "lignin cellulose" relates to a wood material encrusted with lignin.  Moisture may be added to the plate during the hot pressing process by providing an intermediate layer having an excess of moisture between the rear surface of the plate and the press platen.  The carrier plate is maintained at a substantially lower temperature during the pressing process by cooling the press platen adjacent the rear surface of the carrier plate or at least maintaining it at a substantially lower temperature than that of the heated platen in contact with the resin layer.  The Figure shows a portion of a multi-platen press having platens a and a1 capable of being heated or cooled, between which are disposed lignin-cellulose-containing carrier plates b, synthetic resin layers c, polished sheets d to produce a high gloss on the resin surface and intermediate layers e which may be of moist fibrous material if it is desired to increase the moisture content of the plates b or of water impervious material such as rubber if it is desired to maintain the moisture content of the plates b at substantially the same value.  In carrying out the process the press platens a are at first heated, and the platens a1 are either cooled or maintained at a substantially lower temperature than the platens a.  When the resin layers c have hardened the temperature of the platens a may be lowered.

Filed: 1968-03-08
Abstract: 1,174,371. Welding by pressure. VARIAN ASSOCIATES. 8 March, 1968, No. 11566/68. Heading B3R. [Also in Division H1] In making a tubular electrode of wire mesh for an electron tube a tubular mesh is formed by winding a wire comprising a refractory core coated with a metal of lower melting point about a mandrel, the wire having a coefficient of expansion lower than that of the mandrel and heating the assembly to a temperature at which sufficient pressure is produced by differential expansion of the mandrel and wire to cause the wire to wire contacts to weld, the temperature being below that at which the metal coating on the wire melts. A wire 18, of tungsten clad with nickel for a cathode or of molybdenum clad with gold for a grid, is helically wound about the enlarged portion 30 of a high alumina ceramic mandrel 20 and is wound over end rings 12, 14 of molybdenum plated with nickel for a cathode and with gold for a grid, arranged on the portion 30, to form a tubular mesh 16. When the mesh is formed the mandrel is removed from the wire-winding machine and a clamp formed by three part cylindrical sections 24 of ceramic and molybdenum tieing wire 25 is secured about the mandrel. The assembly is heated in a wet hydrogen atmosphere furnace to 1030‹ C. for 20 minutes when due to increased expansion of the mandrel and the clamping action of the sections 24 and wire 25 the wire to wire and wire to ring contacts weld. If the electrode is to form a cathode it is provided after removal from the mandrel with electron emissive material, e.g. barium oxide, strontium oxide or calcium oxide. The ring 12 may be replaced by an annular washer in a plane at right angles to the axis of the mesh and an annular clamp may be screwed to the mandrel to overlap the washer. A wire-mesh screen formed by the wire 18 may partially close one end of the electrode.
