Title: Method for the production of vinyl chloride polymers
IPC: C08F14/06
Filed: 1975-03-05
Abstract: 1468316 Vinylchloride polymerization in water/DM KANEGAFUCHI KAGAKU KOGYO KK 5 March 1975 [5 March 1974 (2)] 9191/75 Heading C3P A process for the production of a vinyl chloride polymer comprises emulsion polymerizing vinyl chloride monomer or a mixture of at least 50 weight per cent of vinyl chloride monomer and less than 50 weight per cent of other vinyl or vinylidene monomers copolymerizable therewith in the presence of 0À5-5 parts by weight, per 100 parts by weight of said vinylic monomer(s), of a salt of a monomer having a sulphonic acid group which is copolymerizable with said vinylic monomer(s), in a mixture of solvents consisting of water and N,N-dimethylformamide in a weight ratio of 30/70 to 55/45, using an initiator for free-radical polymerization. The polymerization may be effected at 20-60‹ C., and may be effected in two stages wherein different ratios of vinyl chloride to copolymerizable monomer are added. The preferred compounds having sulphonic acid groups are alkali metal salts of vinylsulphonic acid, acrylic and methacrylic acid sulphopropyl ester, allyl and methallyl sulphonic acid and styrenesulphonic acid, and the initiator may be a peroxide, persulphate, azo compound or redox system. The emulsions obtained may be treated by a cation exchange resin, and, after distillation of the water, the solutions used to obtain fibres. In the examples, in which the sulphonic acids were used as the sodium salts with ammonium persulphate/ sodium hydrogen sulphite initiator, vinyl chloride was polymerized in the presence of (1) methallyl sulphonic acid; vinyl chloride and acrylonitriles were polymerized in the presence of (2)-(4), (6.1), (9) methacrylic acid sulphopropyl ester; (5), (6.7), (7), (8) vinylidene chloride/methacrylic acid sulphopropyl ester; (6.2) methallyl sulphonic acid; (6.3) allyl sulphonic acid; (6.4) N-ethyl sulphoethyl acrylic acidamide; (6.5) styrene p-sulphonic acid; (6.6) vinyl benzyl p-sulphonic acid; (6.8) vinylidene chloride/methallyl sulphonic acid; (6.9) vinyl acetate/methacrylic acid sulphopropyl ester; (6.10) vinyl acetate/ methallylsulphonio acid; (6.11) methacrylate/ methallyl sulphonic acid; (6.12) methyl methacrylate/methallyl sulphonic acid; (6.13) acrylic acid/methallyl sulphonic acid; (6.14) vinyl bromide / methacrylic acid sulphopropyl ester; (6.15), (6.16) methacrylic acid ester of polyethylene glycol monomethyl ether, i.e. wherein n is 4 and 9 respectively.

Title: Improvements in and relating to hydraulic fluid control means
IPC: F15B13/04
Filed: 1945-04-13
Abstract: 598,670. Hydraulic apparatus ; fluidactuated valves. COMMERCIAL PATENTS, Ltd., and JOVES, G. F. April 13, 1945, No. 9307. [Classes 69 (ii) and 135] A control valve for a reversible hydraulic motor, and applicable, e.g., to the ship proplilsion installation described in Specification 598,654 and to the high-pressure hydraulic control means described in Specification 598,668, comprises a combined piston and lift valve member 3, displaceable in a cylinder 1 solely by hydraulic pressure, for determining the direction of live-fluid flow to the motor, and having a live-fluid inflow port 7, ports 10, 11 connecting with the motor and exhaust ports 8, 9, the arrangement being such that the valve member, during movement from one position to the other, byepasses live-fluid direct to the exhaust ports, thereby gradually reducing the speed of the motor in one direction and accelerating it in the reverse direction. The valve member 3 is actuated by pressure fluid admitted, under the control of a pilot valve (not shown), to either end of the cylinder through restrictions 13, this-pressure fluid being derived either from the same source as that supplied to the motor or from a separate source. When this pressure fluid is derived from the same source, pressure-maintaining means comprising a spring-loaded plunger 19, Fig. 2, in a casing 15, is included in the live-fluid supply to the port 7, Fig. 1, to maintain fluid-pressure upstream of the control valve when the latter is byepassing, thus ensuring that sufficient pressure is available to complete the actuation of the valve after this has been initiated. Pressure-fluid enters the pressure-maintaining means at a port 16 and after raising the plunger passes through a port 17 to the port 7. The connection between the ports 17, 7 may include a distributing valve adapted to byepass the live-fluid, or to direct it to the control valve, or to byepass some of the fluid and direct the rest to the control valve. The pressure-fluid inlet of the pilot valve is connected to the pressure-maintaining means at 18. A connection 23 is provided to take away any leakage past the plunger, such leakage being substantially prevented in the fully raised position of the plunger by engagement of the latter with a seat 20. When the valve member 3 is moved from the position shown to the right, a lift portion 6 of the valve member unseats and permits live fluid to byepass through the port 8, whilst continued movement places the port 9 also in communication with the live fluid until the lift portion 6 closes on its right-hand seat. Specifications 573,713 and 598,667 also are referred to.

Abstract: 787,266. Endless chain elevators. LOW, W. March 26, 1956 [March 31, 1955], No. 9383/55. Class 78 (1). An elevator for sacks and other articles comprises a pair of endless chains between which are mounted supports for the articles, each of which supports comprises a support member which is downwardly inclined towards the front of the elevator, and a flap hinged to the front edge of the support member and normally projecting at an angle to the support member to retain an article, means being provided for maintaining the flap in retaining position and for permitting the flap to lie in the same plane as the support member to cause discharge of an article at a delivery point. As shown, the support member 46 is carried on a bracket 44 in turn mounted on an angle iron 40 extending between a pair of plates 36 secured to opposed links of the respective chains (not shown). The chains run in guide tracks 28 to travel upwards in the front portion 24 of the elevator casing and downwards in the rear portion 26, the two portions being separated by a plate 22 up which the articles slide. The flap 50 is carried on a hinge pin 48 on the support member and carries at each side a bracket 52 supporting a roller 54 which runs on the respective side wall 56 of the casing. In order to lower the flap at a discharge station a dip 58 is provided in the side walls 56 at each station, i.e. above each floor 12, 14 of a building, the articles being loaded on the ground floor by means of a platform 84. To determine at which floor an article is to be delivered track sections (not shown) are adapted to be inserted into the dips 58 in the side walls 56 and these are preferably carried on pivoted arms. Also pivoted shoots 60, 62 are provided at the various floors. In operation all the dips 58 below the desired floor are filled in by the track sections. The articles lift the shoots 60, 62 as they pass the various floors, these shoots immediately falling back into position to receive the article should it be discharged at that floor. The chains are driven by a motor 72 mounted on a bracket which is preferably pivoted so that the driving belt 78 will slip if an obstruction occurs. The elevator may lower the articles instead of elevating them, the doors 60, 62 then being retained in the open position.
