Title: Improvements relating to fluid pressure engines
Inventor: MARSH LESLIE ERNEST
IPC: E05F15/02
Filed: 1960-03-30
Abstract: 971,886. Door operating appliances. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. March 30, 1961 [March 30, 1960], No. 11154/60. Heading E2M. [Also in Division Fl] A double-acting piston and cylinder assembly operable by a gaseous medium, particularly for opening and closing doors, has means for cushioning the piston when the latter approaches the end of either or both of its strokes at least one of the cushioning means comprising a cushioning valve closure member 9 adapted to co-operate with a main outlet opening 5 to close the latter over a terminal portion of the piston stroke and loosely slidable relative to and axially of the piston rod 2 exteriorly of the same under the action of a spring 8 attached at one end to the valve closure member and at the other end to the piston and piston rod assembly and constituting the sole motive connection between the valve closure member and the assembly, so that the piston is cushioned by the compression of both the gaseous medium and the spring, the trapped and compressed gaseous medium thereafter leaking through the restricted passage between the cushioning valve closure member and the piston rod. The cushioning valve closure member 9 comprises a flat faced valve element 10 and a packing cup 11 held against the element 10 by a locking nut 12 to which one end of the spring 8 is attached. The other end of the spring is attached to a piston follower 15 between which and the piston 17 is fitted a packing cup 18. An oppositely directed packing cup 19 is fitted on the other side of the piston, together with a collar 21 attached to a spring 88 connected to a second cushioning valve closure member 99. When the inlet 22 is coupled to the pressure medium gas flows past the packing cup 111 and acts upon the packing cup 19 thus moving the piston 17 to the left and withdrawing the valve closure member 99 from the right hand end of the cylinder. The piston moves freely until the valve closure member 9 closes the outlet holes 5, after which it is cushioned by the compression of the gas trapped between the packing cups 11 and 18, and the spring 8. The trapped gas escapes slowly through the annular space between the valve closure member 9 and the piston rod 2, the escape being controlled by an adjustable choke valve (not shown). The reverse movement of the piston takes place in a similar manner to that just described.

Title: Improvements in or relating to a process for the production of goods of or containing rubber
Filed: 1934-04-17
Abstract: 416,904. Rubber goods. INTERNATIONAL LATEX PROCESSES, Ltd., 10, Lefebvre Street, St. Peter's Port, Guernsey. April 17, 1934, No. 11525. Convention date, June 21, 1933. [Class 70.] A process for producing goods of or containing rubber having perforations therethrough comprises applying a rubber composition, particularly a rubber latex composition, to a perforated deposition backing through the holes in which a gas is forced, the gas passing through the rubber composition while the latter is undergoing partial or complete coagulation. When the process is carried out by means of the apparatus shown, latex is delivered from a reservoir 14 and spread by a bar 15 on to an endless belt 10 of woven rubberized cloth or wire. The belt passes through a drier 17 having a heating unit 18 and air is blown up at 19 through the coated belt. Several coatings may be applied, each coating being thoroughly dried before application of the subsequent one. The film is cut and stripped from the belt and may be finished by dusting and vulcanizing. Vulcanized rubber on the individual woven threads of the belt is preferably hardened by halogenizing to make it non-adherent to the coating, as by treatment with a 7¢ per cent solution of sulphur chloride in carbon tetrachloride followed by a 2-3 per cent solution of bromine in carbon tetrachloride, or with a bromine solution alone, or with a solution of sulphur chloride and bromine in carbon tetrachloride. The latex may be purified as by creaming or centrifuging, and compounded; it may be unvulcanized, with or without vulcanizing ingredients, or prevulcanized, or compounded to form hard rubber or ebonite. For producing dipped articles, hollow perforate forms are used.

Title: Improvements in the thermal cracking of liquid hydrocarbons
IPC: C10G9/00
Filed: 1957-04-11
Abstract: <PICT:0802226/IV (b)/1> In the thermal cracking of combustible organic liquids by burning oxygen or oxygen containing gas in an amount insufficient for the combustion below the surface of the combustible organic liquid to be cracked, the process is carried out under reduced pressure.  In a preferred embodiment using an Aramco crude oil the container 1 is filled to mark A with oil and cooled by means of water introduced into container 2 at 9 and withdrawn at 10. A burner 4 provided with a protective bell 3 is ignited outside the apparatus, hydrogen and oxygen being supplied in about equal parts by volume through pipes 6 and 7 respectively.  After ignition of the hydrogen at the burner mouth 5, the burner 4 is slowly lowered until the bell 3 is about 5 centimetres below the surface of the oil.  The hydrogen is then shut off and the amount of oxygen increased.  The gases produced by cracking are sucked away through pipe 8 so that the pressure in container 1 is about 300-400 torr.  The product gases consist chiefly of carbon monoxide, carbon dioxide, hydrogen, acetylene and ethylene. Specification 795,688 is referred to.
