Filed: 1946-09-11
Abstract: 616,617. Automatic firearms. BREVETS AERO-MECANIQUES SOC. ANON. Sept. 11, 1946, No. 27301. Convention date, Aug. 13. [Class 92 (ii)] A ramp 22 associated with the trigger mechanism of an automatic firearm and serving to control the movements of a breech-block retaining lever 15 pivoted on a part secured to a recoiling barrel 11, is movable from an extreme position parallel to the direction of the recoil movement of the barrel, to a second extreme position forming with this direction an angle A of which the apex is located in advance of the active part of the ramp. As shown, the ramp 22 is formed on an arm 23 of a lever whose other arm is connected by a rod 27 to a piston 29 working in a cylinder 30. This cylinder is secured to an operating rod 28 and in the cylinder is a spring 31 which bears on the piston 29. On pulling the rod 28, the lever moves away from a fixed stop 32 on the cradle 14 to a position bearing on the underside of the breech casing 10 which is secured to the barrel. In so moving, the lever rocks the lever 15, thus withdrawing a sear 17 on the lever from a recess 19 in the breech-block 12. The rod 28 is pushed forwards to stop firing, but need move the ramp through only a small angle, less than angle A, for the sear to engage in the recess 19. The Specification as open to inspection under Sect. 91 describes also modified ways of pivoting the member 23 or guiding it in the cradle. This subject-matter does not appear in the Specification as accepted.

Title: Coated boxboard
IPC: D21H19/82
Filed: 1955-09-26
Abstract: 795,175. Coated boxboard or paper. LOWE PAPER CO. Sept. 26, 1955 [July 19, 1955], No. 27357/55. Class 140. A coated boxboard or paper comprises a base coat of a hydrophobic thermoplastic material bonded to boxboard or paper, a portion of which at least is reprocessed wood pulp, and applied thereover a water-suspension of a mineral pigment with an adhesive component which by weight is 10 to 35 per cent of the weight of pigment used. The base coat may be of polyethylene or one or more of the following materials : acrylonitrile polymers and copolymers, plasticized polyvinylchloride, vinyl chloride and its copolymers, vinylidene chloride and its copolymers, acrylic polymers and copolymers, butadiene-acrylonitrile, cellulose acetate and polyvinyl butyral. The mineral pigments may be one or a combination of kaolin clay, titanium dioxide, barium sulphate, zinc sulphide, calcium carbonate or metallic powder such as aluminium or bronze powder. The adhesives used are selected from casein, starch, protein, butadiene styrene copolymer, acrylic polymers and copolymers or polyvinyl alcohol. To render the hydrophobic base coat acceptable to the aqueous suspension it is pressed while still plastic against a rough surface then cooled; it is stated that in this way polythene surfaces may be made readily print-acceptable. The aqueous top coat is applied to the base coat and dried at temperatures between 120‹ and 200‹ F., after which it is fused with the base coat by heating at a temperature high enough to soften the base coat, and a highly glossy surface may be achieved by pressing against a rotating polished drum maintained at 80‹ to 300‹ F. and with a pressure of 100-1000 1bs. per linear inch.

Title: Improved method of and means for dehydrating or dewatering peat and like subfossil substances
IPC: C10F5/00
Filed: 1937-10-11
Abstract: 503,770. Preparing and drying peat. LINKER, O., and SCHONBORN, Z. G. Oct. 11, 1937, No. 27551. Drawings to Specification. [Class 50] [Also in Group XIII] Peat or like subfossil substance is inoculated with micro-organisms and fermented when exposed to the air in two stages, the second being effected by micro-organisms living at higher temperatures. The raw peat is crushed and roots &c. are removed, acid-reducing substances such as lime or calcium carbonate and if necessary nitrogen containing substahces such as nitrate of lime being added at the same time. A layer of the material, deposited, e.g. on fresh stable horse manure, is sprayed with liquid containing mixed cultures of aerobic and anaerobic micro - organisms together with organisms which act as cellulose destroying agents. After a rise of temperature to 30-40‹ C. a second layer is deposited and treated and further layers are added until a heap 4-6 ft. high is made. When the temperature begins to fall, the mass is broken up and a second heap is built up by layers inoculated with aerobic micro-organisms of cellulose destroying capacity, the temperature rising on fermentation to 50 or 70‹ C. Whilst still warm, the peat is ground and is then extruded in the form of rope from a press in which air is abstracted from the material. Cylindrical or spherical portions of the rope are subjected to shrinking, hardening, and drying. Sheds for drying and storing the blocks comprise stacks of sloping gratings charged from a central elevator and discharged by outer conveyers movable to the successive gratings, or the gratings may lie in zigzag formation delivering to a belt at the base.

Title: Moulds for making welded joints of thermo-plastic material
Inventor: THORNE BERYL FREDA
IPC: B29C45/14
Filed: 1950-11-10
Abstract: 695,217. Moulds for making welded joints of thermoplastic material, e.g. joints between electric cables. TELEGRAPH CONSTRUCTION & MAINTENANCE CO., Ltd. Nov. 9, 1951 [Nov. 10, 1950], No. 27570/50. Class 87 (ii) A mould has means for varying the point of entry thereinto of heating fluid (e.g. hot air which heats the mould before thermoplastic material such as polythene is injected thereinto), thus preventing localized overheating of the mould. Fig. 3 is a side view of such a mould having upper and lower parts A, 8, and Fig. 4 is an inverted plan view of part A. Through the mould extends an axial passage 3 which receives the cable ends to be joined. In the wall of the passage is an annular recess 6 which receives the enlarged end 27 of the rotary mould member D shown in Fig. 5. The middle part 25 of the member D is rotatably received in a bore 5 in the passage 3, and the outer part 26 has handles 30 by which the member may be manually rotated. The mould parts A and B have mating recesses 10 which receive a nozzle through which hot air is blown into the mould. The hot air passes into a port 8 and then, when the rotary member D is in its initial position, as shown in Fig. 4, divides into two streams. One stream enters a groove 7 in recess 6 and heats the mould. The other stream passes through apertures 8' and 40 formed in the part 27 into the mould chamber 35 to heat the mould and a solid sheath P of polythene which surrounds one of the cable ends and forms part of the completed insulation, and leaves the mould through port 41 and bores 42, 43. Immediately after the supply of hot air has been thus initiated, the member D is turned in its bore 5, whereby the apertures 8', 40 are moved out of register with port 8; but hot air continues to enter chamber 35, travelling around groove 7 and thence through apertures 8', 40. When member D is turned, bore 42 is misaligned with bore 43, but hot air escapes through groove 50 and bore 51. Member D is slowly revolved, and when the temperature within chamber 35 is such as to render the polythene sheath therein plastic (as indicated by thermometer 55), the hot air nozzle is disconnected, aperture 8<SP>1</SP> is aligned with port 8 (as shown), an injection nozzle is fitted into 8, 8' (shutting off groove 8), and plastic material is injected into chamber 35. When the chamber is full, excess flows out through bore 43. When a termination is to be made on a cable end, passage end 4 is blanked off. Specification 676,543 is referred to.

Title: Knitted structure
IPC: D04B15/88
Filed: 1947-10-15
Abstract: 652,617. Knitting. AMERICAN VISCOSE CORPORATION. Oct. 15, 1947, No. 27630. Convention date, Nov. 5, 1946. [Class 74 (ii)] Articles 3, knitted in string formation, are joined by yarn 4 formed from thermo-plastic, potentially heat-shrinkable fibres (such as fibres of a co-polymer of vinyl chloride and vinyl acetate or acrylonitrile, which have been stretched whilst in the plastic condition) and the joining yarn is then softened by heat and tensioned, as by passing the structure between heated rollers 5, 6 and draw-off rollers 7, 8. By reason of its tendency to contract, the softened yarn pulls away from the stitches of the articles and disintegrates into blobs which fly out from between these stitches, leaving then substantially free thereof. The method may be used in knitting hosiery, half-hosiery, ribbed tops, sweaters, jackets, wristlets, webs or strips and covers.

Title: Glass color composition and the vehicle therefor
IPC: C03C17/32
Filed: 1952-11-10
Abstract: A vehicle for glass colours composed of inorganic pigments and finely-ground glass, comprises 30-60 per cent by weight of stearic acid, 15-40 per cent of hydrogenated rosin, 10-30 per cent of a resin prepared from rosin by polymerizing the unsaturated resin acids contained therein, 0.1-10 per cent of ethyl cellulose and 2-7 per cent of a stearyl acid phosphate.  If desired, there may be included 0.01-1.5 per cent of phosphorated tall oil as a moisture-resistant agent.  A glass colour comprising 5-20 per cent of an inorganic oxide pigment and 95-80 per cent of finely-ground glass frit may be mixed with the vehicle in the proportion of 1 to 6 parts of glass colour to 1 part of vehicle.  The composition thus obtained may be applied in fluid condition at 47-100 DEG  C. to a ceramic or metal object by means of a squeegee and a screen stencil.  The composition solidifies almost immediately after removal of the stencil. Multi-colour designs may thus be obtained by superimposing a number of different glass colours through stencils in quick succession.  The solidified coatings are then fired on the glass or metal object so as to fuse the glass colour and thereby produce a firmly bonded design on the object.  The ethyl cellulose increases the viscosity of the composition and functions as a hardening agent for the vehicle.  It may have an ethoxyl content of 45-55 per cent.  Lead-borosilicate glass may be used as the glass particle ingredient of the glass colours.
