Title: Improvements relating to apparatus of the movable abutment type actuated by fluid under pressure
IPC: F15B11/02
Filed: 1945-10-09
Abstract: 601,866. Hydraulic machines. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and KERSHAW, N. G. Oct. 9, 1945, No. 26293. [Class 69 (ii)] [Also in Groups XXVIII and XXX] Fluid under pressure is supplied to a movable abutment 2 in such a manner that the applied pressure attains its full value only when the resistance opposing movement of the abutment attains a predetermined value by means of a normally closed auxiliary valve 10 which is opened at a predetermined pressure ; the initial fluid supply to the abutment being through a restricted passage so that the rate of pressure build-up is restricted until the auxiliary valve 10 opens. To operate the abutment in the form of a ram 1 having a piston 2 in a cylinder 3 to the right, hydraulic fluid from a hand-controlled main 6 builds up pressure in a line 9 against the auxiliary valve 10 which may be so constructed as described in Specification 286,818, [Class 135], and to leak through a variable restricted orifice in a non-return valve 14. Such restricted flow moves the ram until opposition sets up back pressure in a line 12 to open the valve 10 and allow unrestricted flow through a non-return valve 13. A reservoir 15 may delay build up of pressure in the cylinder 3.

Abstract: 1,191,023. Embossing. CONGOLEUM INDUSTRIES Inc. 31 May, 1968, No. 26345/68. Heading B6J. [Also in Divisions B2, B5 and C3] A resinous layer having an embossed surface is produced by applying a composition containing a blowing agent to portions of the surface of the layer of resinous composition containing an accelerator which substantially lowers the decomposition temperature of the blowing agent, the agent being soluble in at least one component of the composition, allowing a portion of the agent on the surface of the layer to migrate into the layer and contact the accelerator, heating the layer to decompose the agent thereby forming raised areas on the surface which correspond to the areas of application of the agent, and thereafter cooling the product formed. The resinous composition may be heated after migration of the blowing agent to decompose the portion of the agent within the composition without decomposing the portion of the agent remaining on the surface of composition. The resinous layer may be heated to at least partially gel the composition prior to application of the agent. The agent may be applied to a base, e.g. a transfer sheet, and the resinous composition applied thereover. The agent may be printed on the surface of the layer utilizing printing apparatus in the form of an ink composition containing the agent. A second resinous composition which may be transparent or translucent may be applied, e.g. by spraying or by laminating a film, over the layer prior to heating to decompose the agent. The accelerators may be a metal salt, examples of which are given. The backing web may be formed of a resinous composition, e.g. butadienestyrene, polymerized chloroprene, polyvinyl chloride, polyvinyl acetate, or vinyl chloridevinyl acetate copolymer; felted sheet; woven or knitted fabric of cotton, wool, asbestos, and synthetic fibres; or release paper. The resinous composition containing an accelerator may be of homo-, co-, or ter-polymers of vinyl chloride, with vinyl esters, e.g. acetate, chloroacetate, butyrate; vinyl bromide; vinyl alkyl sulphonates, vinyl ethers such as vinyl ethyl ether, isopropyl ether or chlorethyl ether; cyclic unsaturated compounds such as styrene, mono- and poly-chlorostyrenes; coumarone; indene; vinyl naphthalenes; vinyl pyridines and pyrrole; acrylic acid and derivatives such as ethyl acrylate or chloroacrylate, methyl or ethyl methacrylate, acrylonitrile and methacrylonitrile; vinylidene chloride, bromide or fluoro chloride; unsaturated hydrocarbons such as ethylene, propylene, isobutene, trichloroethylene; alkyl compounds such as alkyl acetate, chloride, or ethyl ether; conjugated and crossconjugated ethylenically unsaturated compounds such as butadiene, isoprene, chloroprene, and 2,3-dimethylbutadiene-1,3-piperylene; diethyl fumarate and divinyl butone; neoprene; SBR and nitrile; polyurethane; polyamides; phenolics; urea-formaldehyde; cellulose esters; epoxy and silicones.

Abstract: 1,183,731. Extruding composite/reinforced tubing. SAMUEL MOORE & CO. 8 June, 1967 [24 June, 1966], No. 26595/67. Heading B5A. [Also in Division F2] Composite tubing adapted to withstand high internal and external pressures is made by passing a metal, e.g. stainless steel, helical coil 12 through the crosshead 64 of a screw extruder 70 wherein a tube 10, of polymeric material is applied to the coil, passing the layered coil through a sizing die 74 of vacuum apparatus 72 to partially embed the reinforcement coil in the inner surface of the tube 10, partially cooling the reinforced tubing in a first cooling bath 76, applying vacuum to the exterior of the cooled tube in vacuum chamber 78 to draw out radially the polymeric material which has flowed too far between the adjacent turns of the reinforcement coils and to smooth the exterior of the extruded tube, and cooling the formed reinforced tube in a second cooling bath 80. A wind-up reel 98 and endless track 99 may be used to draw the tube through the vacuum apparatus and a further cooling bath 94. An external fibrous reinforcement, e.g. braided layers 14, and an extruded jacket of polymeric material, e.g. polyurethane, polyamide, polyolefin or polyvinyl chloride, is then applied to the reinforced tube. The depth of embedment of the reinforcing coil in the inner surface of the tube is arranged so that the coil may be pulled away from the tube at the ends to leave a helical cavity which may accommodate the screw threads of an end fitting, Fig. 7 (not shown). The coil is preferably embedded to a depth of between 30% and 80% of the wall thickness of the tube. The degree of embedment may be controlled by varying the viscosity of the extruded plastics, the size of the die, the outer diameter of the coil, or the extruded tube wall thickness. A specific example setting out various parameters including extruder screw speed, temperatures and vacuum to achieve a specific degree of embedment is given. The polymeric material of the core tube 10 comprises nylon, polyethylene, polypropylene, or polyacetal. In a modification, Fig. 3 (not shown), the reinforced tube is provided additionally with an electric cable layer and an extruded external polymeric jacket.

Filed: 1929-09-04
Abstract: 318,626. Aktiebolaget Separator. Sept. 8, 1928, [Convention date]. Right to Patent relinquished. Recovering waste lubricants.-Used lubricating oil from internal combustion engines &c. is reconditioned by repeatedly centrifuging at from 90-120‹ C. in a strong air current, and then filtering or treating with bleaching material with subsequent centrifuging or filtration or both. For example, used oil in a tank 4 is kept at 95‹ C. by an electric heater 5 and a thermostat, and is forced by a pump 11 through pipes 7, 9, 10 to a centrifugal separator 1 provided with means, e.g. wings on the rotor, for producing a strong current of air in the collecting vessels thereof. The oil is discharged through a spout 2 and returned to the tank. After being circuited 40 times, i.e. for 3¢ hrs., the oil is treated with " Floridin," " Tonsil," or fuller's earth which is added to the tank 4 and circuited with the oil through the pump 11 and pipes 7, 9, 6. The mixture is then passed through the centrifuge, and finally through a filter 12. In modified apparatus the tank 4 is raised so that the oil flows to the centrifuge by gravity in a regulated stream, and by use of two tanks 4 connected alternately to the centrifuge mixing of the more purified with the less purified oil is avoided and the centrifuging treatment shortened. The vapours passing from the separator may be condensed. According to the Specification as open to inspection under Sect. 91 (3) (a) the air current is optional.
