Title: Tubular-shaped launcher for projectiles, in particular fr guided missiles
Inventor: STAUFF EMILE
IPC: F41F3/04
Filed: 1965-02-15
Abstract: 1,222,501. Recoilless weapons; propelling projectiles. NORD - AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 15 Feb., 1965 [26 Feb., 1964], No. 6522/65. Headings F3A and F3C. A recoilless launcher for guided missiles comprises a tube 1 in which is fixed a combustion chamber 6 by means of a ring 5 having arms 5a. A solid propellant 7 mounted on a tube 8 is detonated electrically through ignition wires 12, the gases issuing through apertures 6a in the chamber 6 to drive a piston 3 abutting the rear end of a missile 2. The opposing surfaces of the chamber 6 and tube 1 define therebetween an annular supersonic nozzle 11 through which the combustion gases flow rearwardly to counteract the recoil. This counteraction may be augmented by providing nozzles 13 (Fig. 3, not shown) in the chamber end closure 9. In modifications (Figs. 4, 5, not shown) the apertures 6a are initially closed or partially closed by fusible or combustible plugs 14, 15. A spin is imparted to the missile by blocks 4 received in recesses 3c in the piston and sliding in guides 1a in the tube 1. The torsional force produced by this reaction is counteracted by forming the arms 5a obliquely with reference to the tube axis whereby the rearwardly flowing gases produce a counter-torque.

Title: Manufacture of new interpolymerisation products
IPC: C08F20/62
Filed: 1939-02-28
Abstract: Interpolymerization products which may be of a rubbery or resinous nature are made by polymerizing one or more esters of 1-carboxybutadiene-1-3 (which may be made as described in Specification 523,080) together with acrylic acid, acrylonitrile, an acrylic ester or an a -methyl or a -chloro derivative thereof or more than one of these bodies.  The polymerization may be effected by heating the mixed bodies to 35-100 DEG  C., and organic and inorganic peroxides and per-salts such as benzoyl peroxide, hydrogen peroxide, perbenzoic acid and ammonium persulphate may be used as catalysts; if the polymerization is effected in a shaped vessel the product is obtained as a shaped mass such as a rod or sheet.  Or the initial bodies may be polymerized in aqueous dispersion and if a stable latex is desired an emulsifying agent may be used such as inorganic esters of alcohols such as sodium cetyl sulphate, soaps, quaternary ammonium or phosphonium and ternary sulphonium salts containing high molecular weight hydrocarbon radicles, also polymeric compounds forming viscous aqueous solutions such as gum tragacanth, soluble starch, methyl celluloses, polyvinyl alcohol, partly saponified polyvinyl esters, polyacrylic and polymethacrylic acids (preferably as alkali salts) and interpolymers of acrylic or methacrylic acid with other compounds such as an acrylic or methacrylic ester, and also persalts such as ammonium persulphate.  In another method the initial bodies may be polymerized in an organic solvent which may be a non-solvent for the polymer, for instance an aromatic hydrocarbon, a ketone such as acetone or cyclohexanone, an alcohol or ester such as ethyl alcohol or acetate.  The products form transparent films or coatings and may be used to prepare shaped articles or as ingredients for paints.  In examples the methyl ester of 1-carbon-butadiene-1-3 is polymerized with methyl a -chloracrylate at 100 DEG  C. in the presence of benzoyl peroxide; acrylonitrile in emulsion with sodium cetyl sulphate; methyl methacrylate in emulsion with the sodium salt of an interpolymer of methacrylic acid and methyl methacrylate; methacrylic acid in emulsion with benzoyl peroxide and gum tragacanth; butyl methacrylate in the presence of benzoyl peroxide, the whole being heated in xylene solution to 100 DEG  C.; the b -ethoxy ester of 1-carboxy-butadiene-1-3 is polymerized in emulsion with methyl methacrylate, cetyl sodium sulphate and ammonium persulphate; and the ethyl ester of 1-carboxybutadiene-1-3 is polymerized in emulsion with acrylonitrile and cetyl trimethylammonium bromide and ammonium persulphate.

Abstract: 708,818. Moulding artificial teeth. RYDIN, A. F. March 21, 1951. No. 6730/51. Class 87 (2) [Also in Group VI] An artificial tooth having a translucent veneer and a relatively opaque body portion is made by coating a mould with a veneer-forming composition comprising finely-granulated translucent acrylic resin moistened with a liquid containing an acrylic resin solvent; introducing the bodyforming material, which is finely-granulated dry acrylic resin, into the coated mould; hot-pressing the mould contents; and finishing the tooth by cutting or grinding. Fig. 6 shows a filled mould prior to hot-pressing, the mould haying two incisor tooth cavities, one at right-angles to the other. A coating 4 of the veneer-forming composition is spread on the bottom of the lower half 2 of the mould; the moistening liquid may be a volatile non-solvent, e.g. alcohol, containing a solvent, e.g. chloroform. The thickness of the coating may vary from place to place, and recesses or holes may be formed therein to imitate fillings. The coating hardens whereupon spots 7 of coloured dry acrylate granules are applied thereto, then the body material is applied in two lots 8, 9. This body material is less translucent than the coating material. The lot 8 is yellow or bone-like .in colour, and the lot 9 is translucent; the boundary 10 between the two lots is mixed as by means of a spatula. The cavity 1<1> in the upper mould half 1 is filled with granulated dry yellow or bone-colour acrylate 11, which may be heated to cement the granules together, and the whole is hot-pressed. The resulting tooth is shown in Fig. 7, and this is cut or ground to the shape shown in Fig. 8. More than one coating 4 may be applied to the mould.
