Title: Improvements in or relating to a hydraulic system
IPC: F15B11/08
Filed: 1946-05-21
Abstract: 629,256. Hydraulic presses. DENISON ENGINEERING CO. May 21, 1946, No. 15409. Convention date, May 21, 1945. [Class 69 (ii)] A hydraulic motor, such as a press cylinder is provided with a control system whereby the reciprocating element can be made as well to perform either a single complete reciprocation or repeated reciprocations of full stroke, will reverse on engaging the work, will make a series of short strokes against the work adjustable on length and number, or can be held engaging the work. The control unit comprises a sleeve valve 65 operated by collars 38, 39 engaging by a projection on the ram 33, a manually operated valve 74, and a series of adjustment screws 124, 155 and 164. To initiate operation the valve 74 is moved by handle 85 to allow pressure fluid from the pump 21 to pass into the inside of sleeve valve 65, lifting shuttle 71 and thus directing pressure fluid to the top of cylinder 24. Exhaust fluid from the bottom end of cylinder 24 holds the shuttle 71 in position till movement of the ram ceases, the pressure of this exhaust being controlled by the restricted port 105 in spool 100. The shuttle movement reverses flow to the ram cylinder. If the ram makes its full stroke, tapped arm 35 moves the sleeve 65 to reverse the fluid flow. To restrict the speed of the ram during the end of its first stroke the valve 123 may be partly closed, generating a difference of pressure to lift the spool 100 and byepassing part of the pump output to exhaust. To maintain continuous reciprocation the valve 74 is positioned so that pressure fluid reverses the shuttle at the top of the stroke when tappet arm 35 engages the collar 38. To perform a holding down action the power stroke is first initiated by the valve 74 which is subsequently moved diverting some pressure fluid to hold the shuttle 71 on its upward position. To impart a series of short sharp reciprocations adjacent the work, knob 164 is turned forcing spool 160 downwards to connect passages 63, 147. Pump fluid supplied to the lower end of the ram cylinder through pipe 32 will also flow through pipe 136, lifting spool 132 and connecting pipe 147 to pipe 149, thus allowing reversal of shuttle 71 to reverse the ram movement. The time of this short movement is controlled by the valve 153 restricting movement of the spool 132. The number of such short strokes is adjusted by the distance spool 160 being forced downward by screw 164, each stroke moving piston 166 to discharge fluid into space 158. When this is full, spool 160 closes passage 147 and a normal return stroke is then made. Fluid from space 158 is exhausted by valve 184 when this is unseated by the sleeve 65 at the upper end of its stroke so that the whole cycle can be repeated at will. If desired, the movement of the valve 74 can be controlled remotely by hydraulic pressure in place of handle 85.

Abstract: 863,650. Purifying olefin polymers. PHILLIPS PETROLEUM CO. May 14, 1958 [Aug. 16, 1957], No. 15440/58. Drawings to Specification. Class 2(6). Solid olefin polymers are recovered from solution by introducing the solution to a polymer concentration zone, heating to vaporize the solvent, regulating the amount of heat supplied in response to changes in a property of the effluent from the zone which changes are proportional to the concentration of the polymer so as to maintain the concentration of polymer within a predetermined range, dispersing the concentrated polymer solution removed from the zone in water to precipitate polymer, and recovering solid polymer from the mixture of solvent and water. Specified monomers are ethylene, propylene, butylene and their mixtures with butadiene and isoprene. The polymerization may utilize chromium oxide catalysts, organo-metallic e.g. Al compounds and metals such as sodium, potassium, lithium, rubidium, zinc, cadmium or aluminium associated with Group IV halides. Paraffins, alicyclic hydrocarbons, aromatic diluents are preferred solvents. The specified property may be the refractive index or the dielectric strength of the polymer solution. The solvent may be removed by using indirect heat exchange. Apparatus for carrying out the process is described. Specification 835,301 is referred to.

[Also in Group XXXVI] A printed circuit or other pattern in metal is made by (1) producing a latent image of the pattern on a sensitised surface e.g. by light, (2) charging the image electrostatically and developing the image by coating with finely powdered metal e.g. Woods metal, and (3) using the metallised image, after consolidating by heating and rolling if desired, as a cathode upon which a final coating of copper or other metal is deposited electrolytically. The sensitised coating may be zinc oxide dispersed in a resin binder and coated on an insulating layer e.g. a thermosetting resin, which is then submitted to corona discharge using a mask pattern as described in Specifications 864,370, 867,834, 867,835 and 871,041. The powdered Woods metal, or other alloy of Bi, Pb, Sn, Cd and In, is then applied to the image for example as described in Specifications 864,370 and 871,041. Copper powder may also be incorporated. The coating is then consolidated by heating and passing between pressure rollers, with a facing sheet of cold copper foil. The image is then plated with copper.
