IPC: D04H1/68
Filed: 1969-07-28
Abstract: 1,257,095. Boots &c. KANEGAFUCHI BOSEKI K.K. 28 July, 1969 [27 July, 1968], No. 37832/69. Heading A3B. [Also in Divisions B2 and Dl] The insole, toe lining, quarter lining, heel pad or sole pad of a shoe is made from a leather-like sheet material produced by impregnating a fabric with an aqueous solution containing a water soluble polyvinyl acetal and an aldehyde, heating the impregnated fabric at 50-130‹C. to insolubilize the polyvinyl acetal, to give a microporous and waterinsoluble polyvinyl acetal resin adhering to and covering the structural fibres of the fabric as a unitary three dimensional network, impregnating the fabric with an emulsion or solution of at least one resin other than polyvinyl acetal resin and curing the resin impregnated fabric by heating to 50‹-180‹C. The fabric may be a non-woven fabric, pile fabric with projecting filaments or a napped fabric and may be made from cotton, silk, wool, cellulose acetate, viscose rayon, cupra, polyacrylonitrile, polyamide, polyester, polyvinyl alcohol, polyvinyl chloride, polyvinylidene chloride or polyolefin fibres. The polyvinyl acetal used may be produced by the reaction of polyvinyl alcohol with formaldehyde, acetaldehyde, butylaldehyde, glyoxal or benzaldehyde and may have a degree of acetalization of 10-30 mole %. The solution of polyvinyl acetal which may also contain an acetalization catalyst, e.g. an acid or salt thereof, a pore forming agent, e.g. starch or dextrin, or a colouring agent, may be applied by pad-squeezing, doctor coating, roll coating, brush coating or spraying from one or both sides of the fabric. The fabric may then be heated, e.g. by dry heat or steam, to promote acetalization of the polyvinyl acetal, e.g. to a degree of acetalization of 30-85 mole %. The product may then be buffed or abraded or sliced or pressed to the required thickness, and then treated with the other resin which may be a polyester, polyamide, polyurethane, styrene/butadiene or nitrile/butadiene rubber, natural rubber, urea-, melamine- or phenol-formaldehyde resins, polyacrylonitrile, polyacrylate or polyvinyl chloride. The other resin is applied in the form of an emulsion or aqueous or organic solvent solution which may also contain plasticisers, e.g. butyl lauryl phthalate, butyl phthalyl butyl glycolate, dibutyl phthalate, diethyl phthalate, di-2-ethyl hexyl phthalate, dimethyl phthalate, di-n-octyl phthalate, tricresyl phosphate, ethylene glycol and glycerine, condensation catalysts, e.g. hydrochloric acid salts of organic amines, magnesium chloride, zinc nitrate, ammonium chloride and primary ammonium phosphates, colouring agents, softening agents and hardening agents. Curing may be effected on a cylinder heating apparatus or by compression by and between two hot plates under a pressure of 3-20 Kg/cm<SP>2</SP>. The product may then be coated with a liquid containing at least one natural or synthetic resin, e.g. a polyurethane, polyamide, vinyl polymer, styrene/butadiene or nylon/butadiene rubber, cellulose acetate or nitrate or natural rubber on at least one surface to form a grain side layer thereon.

Abstract: 344,546. Furnace and retort doors. WILD & CO., Ltd., M. B. and TURNER, J. A., 71, Argyle Street, Nechells, Birmingham. Dec. 14, 1929, No. 38395. [Classes 51 (ii) and 55 (i).] Mechanism for operating the doors of furnaces, retorts, &c. comprises a longitudinally movable arm a, a bell. crank lever d on the arm having a part adapted to engage the door f at e, a second bell-crank lever h connected by a link g to the bell-crank d and operated by a cam i, and a crank m for moving the arm a. The mechanism 'is mounted on the machine for charging and discharging the retorts and the horizontally slidable arm a is mounted on rollers b, c and carries at its forward end the bell-crank lever d one arm of which is notched at d<1> to engage a lip e at the upper part of the door f and the other arm is connected by the link g to the bell-crank lever h at the rear end of the arm a. A depending portion k at the front end of the arm a carries an adjustable abutment roller l to engage the lower part of the door. The arm a is given a complete to-and-fro movement by a partial revolution of the crank m connected with the arm by a rod n and driven through gearing by a motor o, and at the end of the forward movement when the lever d has been brought beneath the lip e the roller cam i on the crank shaft acts on the bell-crank lever h to raise the lever d and lift the lower edge of the door clear of the groove in which it engages. During the raising movement the roller l engages the door and the crank movement is taken up by a spring p in the crank arm. By continued motion of the crank in the same direction the arm a and door f are drawn back, the shape of the cam i being such that no motion is given to the lever h during this movement. The machine is then moved across the furnace front to enable the charging or discharging mechanism to operate.

An auxiliary two-speed gear which may be fitted to existing light motor cycles so as to provide a high speed range for normal road work and a high power range for off road work and hilly terrain, comprises three sprockets 58, 60, 62, the sprocket 60 being chain-driven from the normal change-speed gear of the cycle and being selectively clutchable to the sprockets 58, 62 by an axially shiftable key 106. The sprockets 58, 62 drive sprockets of different diameter fast with the cycle rear wheel hub to give high and low ratios. The sprockets 58, 60, 62 are rotatably mounted on a shaft 56 which is rotatably mounted in, and projects from, a housing 44 which is secured to one of the trailing arms of the rear forks of the cycle. The clutch key 106 permanently connects the sprocket 60 to the shaft 56 and is shifted axially by a rod 108 actuated either by direct manual operation of a radial handle 110, or by actuation of a cable mechanism fast with the handle. The handle 110 is fast with a guide barrel 114 slidable in a longitudinal bore in the housing and formed with dished portions 118, 120 cooperating with a spring-pressed ball to urge the handle, and hence the clutch key, to its end positions. Where the handle 110 is actuated by a cable the portions 118, 120 and ball are dispensed with and the barrel is urged to one end position by a spring.

Title: Valve assemblies
IPC: F16K31/365
Filed: 1974-09-03
Abstract: 1480960 Valves P L DAWSON 3 Sept 1974 38560/74 Heading F2V A valve comprises an inlet 2 and an outlet 3, a closure member 11 actuated by a diaphragm 5, and an auxiliary valve 6 communicating with a chamber 7 on one side of the diaphragm for causing flexing of the diaphragm. The latter is of flexible rubber-like material and has a thick inner portion 10a, and a thin outer portion 10b. In operation, pilot valve 6 is opened and fluid in chamber 7 escapes through a passage 25 so that pressure from inlet 2 forces closure member 11 to move away from seat 13 and the valve opens. When pilot valve 6 is closed, chamber 7 is filled through apertures 15 in the conical end of the closure member, and along a passage 16 having a clearing pintle 17 therein, and the pressure in chamber 7 flexes the diaphragm to thus move the closure member to its closed position on seat 13. A deflecting lip 21, and a clearance 18 are provided on the closure member. In a modification, lip 21 is not included, a removable tapered pintle 40, Fig. 2, projects into part 19 of the closure member, a spring 50 assists in the initial closing of the valve, and valve 6 is replaced by a valve 45 which is selectively connected to chamber 7 or to exhaust at 49.

Fuel from an electromagnetically operated injector 16 is mixed with air or exhaust gas flowing through a sleeve 15 surrounding the injector body. The air or exhaust gas flow is caused by the pressure difference between the manifold 13 and the air or exhaust gas inlet, e.g. the engine air cleaner or exhaust system. The downstream end of the sleeve 15 may take various forms, Figs. 2 to 5 (not shown). The air may be heated by heat exchange with the exhaust gases. The heated air or exhaust gas may pass through an annular passage (47), Fig. 4 (not shown), surrounding the flow path from the sleeve outlet orifice (41). The atomized mixture may flow from the sleeve outlet orifice 21 through a tube (55), Fig. 5 (not shown). A plurality of fuel injectors 8, Fig. 6, fed with fuel by a pump 61, have their supply pressure determined by a by-pass valve 63 subjected to the pressure of air or exhaust gas flowing to the injectors. The fuel injectors may be of the type described in Specification 1, 064, 679 and the fuel injection system may include features disclosed in Specification 1, 107, 989.
