Title: Process of and apparatus for making wads for shot-gun cartridges
IPC: F42B7/08
Filed: 1933-03-02
Abstract: 415,778. Wads. DEHN, F. B., 103, Kingsway, London.-(Western Cartridge Co. ; East Alton, Illinois, U.S.A.) March 2, 1933, No. 6419. [Class 9 (i).] Wads for shot-gun cartridges are moulded by first applying a preliminary condensing pressure to the wad-forming material and then a final finishing pressure to both faces of the wad. In the illustrated machine tacky or sticky material is placed in a rotary-mouldtable machine comprising a ring of die-holes on the rotating table 17 and sliding top and bottom plungers 48, 36 working in conjunction therewith. The top plungers are raised and lowered by engagement with double cam tracks 42, 43 and the bottom plungers by similar cam tracks 33, 34. The part of the cam track 33, corresponding to the filling station, can be raised and lowered by screws operated by worm gear in order to vary the charge received by the dies. In operation, the bottom plungers are lowered in the dies prior to charging, and then the top plungers enter the dies and compress the material lightly, the bottom plungers meanwhile also moving downwards, but at less speed than the upper ones. At the next stage the lower plungers rise slightly, while the upper ones remain stationary, in order to equalize the pressure throughout the material, and afterwards both plungers approach one another simultaneously to apply the main pressure, which is maintained for the greater part of the revolution of the table of the machine. Finally both plungers are retracted and while in this position are cleaned by passing rotary brushes 87 and then oiled by passing over similar brushes. The upper plungers then descend again and eject the moulded wads on to a delivery belt 92. The material is fed past a series of fixed baffles 75, Fig. 2, by means of a driven belt passing over the rollers 71, 72. In the illustrated machine the plungers are fixed in sets of seven on common sliding heads 35, 44, and the upper plungers are each spring- mounted in the head so that the pressure exerted can be equalized over the whole seven.

Abstract: 491,385. Brackets for posts; scaffolding ; stands. SIDWELL, R. R. March 4, 1937, Neo. 6444. [Classes 20 (i) and 20 (ii)] [Also in Group XIV] A bracket for connecting articles to upright scaffold poles, or to other kinds of poles, pillars and the like, comprises two or more flanged segments F adapted to fit together when arranged in contact with the pole A and to fit into a peripheral space provided between a member B secured at any desired position to the pole. Further, the flanges of the segments rest upon the top of the member B which member is in the form of a hollow sleeve or ferrule or split collar and is secured to the pole by a set screw C or other fastening device. The segments shown have portions G of reduced thickness and, when in position, rest upon a ledge of the sleeve B. The flanges have holes H for the attachment of articles, or such articles may be cast integrally with the segments or welded to them. In a modification, the member B comprises two semicircular members adapted to fit on opposite sides of the pole and to be clamped together and to the pole by screws passing through laterally extending flanges thereof. In another modification, the segments are formed with depending portions adapted to fit around the outer surface of the sleeve. The brackets mav be adapted for use with posts of circular, triangular, square, hexagonal, or of any other cross-section. In one application of the invention, Fig. 6 (not shown), the segments are formed integral with the tiers of plates. of a cake stand.

Filed: 1917-05-11
Abstract: 113,380. Hunter, P. V., Beard, J. R., and Electrical Improvements, Ltd. May 11, 1917. Protective arrangements.-In protective arrangements for distribution systems, of the kind in which current transformers connected by pilot wires are employed as described, for example, in Specification 3896/04, the operation of the relays in the pilot wires by the capacity current in such wires is avoided by the employment of an auxiliary conductor and which is open-circuited and so located that the protective devices are unaffected by the capacity current. In the form shown in Figs. 1 and 2, the compensating conductors D, D', which are connected across the secondaries B, B<1> of the current transformers and are opencircuited, are constituted by tubular metal shields round the pilot wires C. The capacity currents are confined to the card sectors C, D, D' and the transformer secondaries and do not affect the relays A, A<1>. In the form shown in Fig. 3, the relays A<2>, A<3> are of the balanced type each with two windings connected as shown so that the equal capacity currents in the pilot wire and compensating wire balance one another in their action on the relays. In this form, the compensating wires are arranged as companion cores to the pilot wires.

Title: Copolymers for making acrylic fibers having improved basic dyeing properties
IPC: C08F20/42
Filed: 1963-02-21
Abstract: Fibre-forming dyeable copolymers are made by copolymerizing a mixture comprising: (a) at least 80% by weight of acrylonitrile, (b) up to 19.95% by weight of another monoolefinic compound, and (c) from 0.05 to 2.0% by weight of cinnamic acid, or a nuclear alkyl or halogen derivative thereof.  Comonomers (b) specified are acrylic, methacrylic and chloroacrylic acids and the amides and esters thereof, e.g. methyl acrylate and methacrylate, methacrylonitrile, vinyl and vinylidene halides, vinyl esters, e.g. vinyl acetate, N-vinylimides, vinyl substituted N-heterocylic amines, vinyl ketones, vinyl sulphonic and vinyl benzene sulphonic acids, styrene, vinyl naphthalene, N-vinyl carbazole, vinyl furane, methylene malonic esters and diethyl citraconate. Polymerization is preferably carried out by continuously adding to a reaction vessel separate aqueous feeds containing monomer, potassium persulphate and sulphur dioxide partially neutralized with sodium bicarbonate.  The resulting copolymers may be formed into fibres from solutions in dimethyl formamide, dimethyl acetamide, ethylene carbonate, butyrolactone, moist nitromethane, dimethyl sulphone and aqueous solutions of sodium thiocyanate, zinc chloride or lithium bromide.  In addition, fibre-forming blends may be made by mixing 80 to 98% by weight of one of the above copolymers with 2 to 20% by weight of a copolymer of 10 to 70% by weight of acrylonitrile and 30 to 90% by weight of a vinyl substituted tertiary N-heterocyclic amine, e.g. vinyl pyridines and imidazoles, the blend being so proportioned that the vinyl heterocyclic amine constitutes 2 to 10% by weight thereof. The blends may be made by dissolving the two copolymers in a mutual solvent, e.g. dimethyl acetamide.
