Patent GB-563720-A (GB)
Title: Copolymers of vinyl chloride
IPC: C08F214/06
Filed: 1942-09-21
Abstract: Improved vinyl copolymers are made by copolymerizing a mixture containing vinyl chloride in predominant amount, vinylidene chloride and from 4-15 per cent of the monomer mixture of vinyl acetate. Preferably, the amounts of vinyl chloride and vinylidene chloride comprise 45-90 per cent and 4-40 per cent respectively of the weight of the mixture, and, further, the preferred ratios of vinyl chloride to vinylidene chloride are 85-90 to 15-10 respectively.  The copolymers may be prepared by mass or emulsion polymerization or by polymerization in an organic medium which is a partial or non-solvent for the copolymers.  Specified plasticizers for the copolymers are tritolyl phosphate, dibutyl sebacate and dioctyl phthalate.  Examples are given of the copolymerization of the three monomers in aqueous emulsion in the presence of sodium lauryl sulphate, a mixture of disodium phosphate and citric acid (McIlvaine buffer) and sodium perborate with or without the addition of carbon tetrachloride.  The emulsion may be broken by addition of alcohol or an electrolyte, e.g. potassium chloride to give a product soluble in ethylene dichloride.

Title: Improvements in or relating to apparatus and devices for feeding material to weighingmachines, crushing machines, and other apparatus and machines
IPC: B65G47/00
Filed: 1924-05-30
Abstract: 243,552. Redler, A. May 30, 1924. Apparatus fitted to conveyers.-The material is fed to the weighing-hopper by a chain conveyer, and means, automatically controlled by the movement of the weighing-scale, are provided for regulating the flow. Fig. 1 shown a feed regulator g arranged to act on the lower run of the chain conveyer a in a trough b and to be operated by a preliminary movement of the weighing-hopper previous to a final movement which cuts off the supply to the weigher, the conveyer delivering the dribble feed of the material past the regulator into the portion of the trough b above the weigher. The chain a and trough b are constructed as described in Specification 169,262, [Class 78 (i), Conveyers &c.], according to which the links of the chain form with the bottom stratum of the substance conveyed an improvised solid band supporing the remainder of the load when travelling over a surface without apertures. The trough b has an inlet c and an outlet d above the weigher c, and the chain a is driven by means of sprocketwheels f. An arm j of the weigher engages a slot k in a rod i connected to a lever on the spindle n of the regulating flap g. A platform o supports the upper run of the chain. The material entering at c falls through the upper run of the chain on to the lower run which conveys it to the outlet d. Downward movement of the arm j moves the flaps g downwards, and a weighted lever h holds the flap in its extreme position. The conveyer chain may have extended projections adapted to act as rakes or as cross-bars on one or both sides, or above, or below. Fig. 4 shows a modification in which the inlet to the trough b is in the form of a hopper c<1>, and the upper run of the chain a passes beneath the outlet of the hopper and conveys the material over and past the end of the platform o. After passing the platform, the material falls through the upper run of the chain to the lower run and is conveyed past the regulating flap g to the outlet d. The chain may be associated with the hopper c<1> so as to abstract the material therefrom as described in Specification 159,236, [Class 78 (iv), Loading &c.]. Specifications 166,079, [Class 78 (iv), Loading &c.], and 177,062, [Class 24, Chains &c.], also are referred to.

Abstract: 557,093. Refrigerating. HALL, Ltd., J. &. E., and HIRSCH, M. Sept. 24, 1942, No. 13427. [Class 29] Cold air systems.-Air or other like medium circulating in a closed cycle and undergoing compression, cooling and expansion through a restricted orifice without performing external work is employed for cooling to a low temperature a secondary medium, the cooling of the compressed air being effected in one or more stages by a refrigerating machine, and in other stages by the cold of the expanded air returning to the compressor. As shown in the diagram of Fig. 1 the air is raised in pressure from 40 to 100 atmospheres in a compressor a, cooled by well-water or other natural source in a cooler b, by the returning cold air in interchangers d, h and by a refrigerating machine in a cooler i between the interchangers. It expands through a restriction e and cools a secondary medium in an interchanger f. This secondary medium may be precooled in an interchanger by the returning cold air. Several different arrangements are described of successive cooling of the compressed air by the cold air and by the refrigerating machine, which may be in stages.

Abstract: 232,805. Pitts, J. W. June 2, 1924. Screw and like propellers; propelling, steering, and manoeuvring by reciprocating plates; driving-arrangements for screw propellers.-Relates to screw propellers which are reciprocated and rotated and have a number of radiating vanes provided with flaps for closing the spaces during one direction of reciprocation and consists in making the vanes of decreasing width from root to tip and of gradually changing angle from a radial plane at the root to a plane at right angles thereto at the tip. A reciprocating vertical rod 1, Fig. 2, passes through the hollow rotary shaft 2 the end of which supports the blades 9. The reciprocating and rotary movements are derived from mechanism as described in Specification 232,804, [Class 4, Aeronautics]. The enlarged end of the shaft is provided with openings for adjustment of the part 6, and also has slots receiving the lugs 10 of the blades which have their greatest width and pitch at the root end. The blades are inclined downwardly with respect to the vertical shaft and carry on their lower edges vanes 12 which swing up into the horizontal against rings of wire 13 on the downward stroke of the propeller. The outer tips of the blades are braced by a rim 14. The gear box is mounted so as to be movable for tilting the axis of the propeller shaft for steering purposes and for joint horizontal and vertical propulsion. When two or more propellers are fitted to aircraft, opposed tilting is utilized for hovering.

Both product and intermediate may be used to stabilize vinyl resins.  Examples specify the reaction of dibutyl or dioctyl tin oxide with S-benzyl, -cetyl, or -octyl isothiouronium salts which may be benzoate, thiobenzoate, laurate, cinnamate, acrylate, monooctyl maleate, octoate or lauryl mercaptide; and with the reaction product of this urea and BETA-propiolactone. Isothiouronium halides are prepared by reacting this urea with an alkyl or aralkyl halide, e.g. benzyl chloride, cetyl bromide; and the carboxylate, thiocarboxylate or mercaptide is obtained by reacting the corresponding halide with a carboxylic or thiocarboxylic acid, or a mercapton, e.g. benzoic acid (see Examples 1, 2, 7 and 8).  Many other salts of the above types are named.  An isothiouronium carboxylate of the type <FORM:1026404/C2/6> is obtained by reacting thiourea with a lactone, R1, R2, R3 and R4 being hydrogen atoms or hydrocarbon radicals.ALSO:Vinyl resins are stabilized with organo tin compounds (see Division C2) prepared by reacting an alkyl tin oxide with an iso-thiouronium salt.

Abstract: 623,392. Hot-water tanks &c. WIDD, T. V. May 4, 1946, No. 13587. [Class 64(i)] In a heat-retaining vessel, e.g. a hotwater tank, with inner and outer metal walls, a, b connected together at a mouth or neck so as to enclose a space in which a vacuum or partial vacuum is maintained, a ring c forms a junction between the two walls a, b, or between the inner wall a and a member d carried by the outer wall b, and has means for mounting an immersion heater within the vessel. In the form shown, the member d is an annular web of low heat-conductivity metal, e.g. tinned iron. The space between the walls a, b is evacuated through a copper or other bendable tube e, which after sealing is folded inside the vessel. If re-evacuation is necessary, the tube may be pulled out. The surfaces bounding the vacuum space are polished. In another form, the heat-retaining vessel is enclosed within a cold water tank which has an opening at the bottom opposite the openings in the walls a, b. A flanged ring connects the three casings around these openings, the flange extending into the space between the two inner casings. The ring carries the water inlet and outlet pipes for the heat-retaining vessel. Specification 623,443, [Group XI], is referred to.
