Title: Metal-casting apparatus of the pressure type
IPC: B22D17/12
Filed: 1937-03-18
Abstract: 481,829. Casting-machines. MADISONKIPP CORPORATION. March 18, 1937, No. 8022. Convention date, April 1, 1936. [Class 83 (i)] [Also in Group XXVI] Moulds.-In order to avoid pressure on and thus loss of metal when transferred from a container 44 to a recess 38 in a replaceable mould 13, 14 this recess is made large enough to hold all the metal required to fill the mould cavity 36. Metal is poured into a cylindrical container 44, having the same diameter as the cylindrical recess 38, after the mould half 14 has been withdrawn by breaking a toggle 24, by pressing down the end 34 of a treadle 35, and rotating a pinion 19 by a hand wheel 22. The capacity of the container is adjusted to that of the mould by moving a plunger 54 relative to its actuating piston 57 by rotating a screw-coupling 75 and locking it by a nut 76. The mould is then closed and locked bv pressing down the treadle 35 and the plunger 54 raised by admitting compressed air below the piston 57. The plunger transfers the metal charge to the recess 38 and before the metal reaches the gate 37 the plunger also enters the recess and then forces the metal into the mould cavity 36. The container 44 has a removable liner 46, is adjusted to engage the mould in use by C- shaped members 51 of various thickness, and is aligned to the stationary mould part 13 by pins, not shown. To withdraw the plunger entirely for renewal &c. a part 65 of the coupling is removed and the rest 64, with the actuating cylinder 58, is turned about pivots 61.

Title: Fluid flow control valve assembly
Inventor: ROUSSET RENE PAUL
IPC: F16K1/46
Filed: 1960-03-09
Abstract: 906,654. Valves; pressure-relieving devices. BRITISH OXYGEN CO. Ltd. March 9, 1961 [March 9, 1960], No. 8288/60. Class 135. A valve assembly has a housing 1 with a stepped bore 2 having an inlet 4 connected to a container, e.g. a gas cylinder, and an outlet cross-bore 14 adjacent a seat 7 on a resilient seal 8, the seat being retained by a member 10 threaded into the bore 2 and sealed with respect thereto by a flexible ring 11. A valve spindle 17, which is slidable through the member 10 and an associated seal 20, carries a spring ring 22; the spindle is threaded into a movable closure member 24 in the bore 2, the member 24 supporting a ring 25 of resilient gas-impervious material that is held in place by a sleeve 27 secured by a nut 29a. The sleeve length is such that the ring 25 is slightly extruded by the controlled fluid, e.g. gas, to co-operate with the seat 7, an aperture 30 being provided through the sleeve 27 to admit the gas to the ring 25. The member 24 is seated by the combined action of a spring 31 and the inlet gas-pressure; the valve is opened by depressing the spindle 17, e.g. via a threaded member moved axially by rotation of a nut through a pulley with an operating cord. Rotation of the spindle in the member 24 is prevented by a piece of nylon cord in a cross-bore 32. The degree of opening of the closure member is dependent upon the extent the spindle 17 protrudes from the member 10. Removal of the latter enables all the valve parts to be withdrawn. Passages 36, 43 connect a burster disc apparatus across the closure member 24, the apparatus consisting of a copper disc 38 between washers 37, 39, the latter being shaped to encourage the copper disc to dome outwardly and so avoid its irregular rupture. Upon the disc bursting due to the inlet pressure exceeding a given value, the gas reaches the passage 43 via a chamber 42 and slots 44 in the face of ring 41 held in place by a plug 45.

Title: Process for the manufacture of terpolymers containing carboxyl groups which have adhesion to metals
IPC: C08F214/06
Filed: 1975-02-28
Abstract: Copolymers based on vinyl chloride are prepared from vinyl chloride, vinyl esters and ethylenically unsaturated mono- or dicarboxylic acids or anhydrides thereof by polymerisation in an aqueous suspension in the presence of monomer-soluble free-radical catalysts and in the presence of suspension stabilisers. Use is made of 70 to 90% by weight of vinyl chloride, from 10 to 30% by weight of a vinyl ester of an aliphatic monocarboxylic acid having 1 to 11 carbon atoms and from 1 to 10% by weight of an ethylenically unsaturated mono- or dicarboxylic acid. The process is carried out in the absence of organic solvents, either at a water:monomer phase ratio of from 0.8:1 to 1.8:1, where, after the polymerisation temperature has been reached, from 50 to 20% by weight of vinyl chloride and, if desired, vinyl ester are continuously metered in to a conversion of from 70 to 85%; or at a water:monomers phase ratio of from 0.8:1 to 1:1, where, after the polymerisation temperature has been reached, from 50 to 30% by weight of vinyl chloride and vinyl ester are continuously metered in to a conversion of from 70 to 85%, and from 50 to 30% by weight of water and unsaturated carboxylic acid dissolved therein are continuously metered in from a conversion of from 30 to 50% to a conversion of from 60 to 75%. This procedure gives products which form a clear solution and have excellent adhesion to metals.
