Title: Improvements in guns and in particular automatic guns making use of ammunition in the form of cartridges
IPC: F41A21/12
Filed: 1955-01-27
Abstract: 765,300. Firearms. BREVETS AERO-MECANIQUES SOC. ANON. Jan. 27, 1955 [Feb. 16, 1954], No. 2498/55. Classes 9 (1), 92 and 119. Cartridge cases each have two annular bearing areas b, e, Fig. 1, located one ahead of the other adapted to co-operate respectively with two annular abutments b', e' in the cartridge chamber 1, these areas and abutments being so shaped and positioned that the cartridge, near the end of its movement of introduction into the chamber 1, is first braked by deformation of the braking area e on the abutment e', and is then positioned accurately by engagement of the second positioning area b against the abutment b' in the chamber 1. The braking area e is constituted by the frusto-conical shaped shoulder of the cartridge having an apex angle of about 45 degrees whilst the corresponding frusto-conical abutment e' in the chamber 1 has an apex angle of about 30 degrees. Deformation of the area e brings its apex angle substantially the same as that of the abutment e' until the annular flange b in the rear of the cartridge meets the abutment b' to position the cartridge accurately. Fig. 4 shows two locking members 5 which bear against the end face of the cartridge 2 by their inner ridges X. The members 5 are brought into locking position by pivoting about this diametral line X and the cartridge is positioned in the chamber, this displacement being produced by forward movement of a part 6 after the members 5 have finished their forward movement. The accurate positioning of the cartridge in the chamber ensures that the extent of the pivoting movement of the members 5 remains substantially constant and prevents contact between the members 5 and the rear of the gun barrel.

Title: Production of oxygen-containing compounds by oxidation of hydrocarbons
IPC: C07C27/10
Filed: 1950-02-01
Abstract: Hydrocarbons containing more than one carbon atom are partially oxidized in the vapour phase at elevated temperature, the products are rapidly cooled to stop oxidation by means of an aqueous quenching medium which dissolves at least part of the formaldehyde present, and the pH of the solution thus formed is maintained between about 4.0 and about 7.0, preferably at about 5.0.  The peroxide content of the products may be reduced by catalytic decomposition before the quenching operation, catalysts specified being carbon steel rings, soda glass tubes, aluminium, activated charcoal, tungstic oxide, or alumina.  In an example, a mixture of isobutane, oxygen, and inert gases is passed continuously through a reaction zone at 600-650 DEG F., and then over carbon steel rings.  The product is dissolved in an aqueous solution which is continuously withdrawn and cooled, a sidestream being removed for recovery of formaldehyde, formic acid, methanol &c., and the remainder recycled after addition of water and alkali to maintain the volume and pH of the quenching solution. Specification 697,906 is referred to.

Abstract: 765,061. Luminescent apparatus. KODAK, Ltd. Jan. 28, 1955 [Jan. 29, 1954], No. 2657/55. Class 39(1). [Also in Group XX] A reflex sight or photographic viewfinder has a reference mark formed by an edge of an at least partially transparent member of fluorescent material the light from which is reflected by a semi-reflecting surface so that an image of the edge appears superimposed on the object field being viewed. As shown in Fig. 2 the reference mark is formed by the rectangular edge 28 of a sheet 23 of transparent plastic material in which fluorescent particles are embedded. Light from such particles, as indicated at 27, passes to the edge 28 by internal reflection in the sheet and emerges into the viewfinder 20 to be reflected by a concave surface 22 thereof and by a semi-reflecting plane front surface 24 thereof to reach the eye 13. An opaque mask 25 limits the size of the frame. In the modification shown in Fig. 5 the viewfinder consists of a front negative lens 51 moulded integrally with the casing 52 in which is inserted a member 55 of fluorescent plastic material having a downturned edge 41 and held in place by a member 54 bearing a positive eye-lens 53. Fluorescent light is transmitted within the member 55 by internal reflection and is reflected by an inclined edge 48, Fig. 7, to pass to the lens 51 and be reflected by one surface thereof to the eye-lens 53. In a modification the casing 52 itself may be formed of fluorescent material. Alternatively the member 55 of Fig. 5 may be replaced by a differently sized member to suit a different objective or the member 55 may carry in front a semi-reflecting surface and so itself act as a viewfinder. Specification 764,054 is referred to.

Patent GB-825268-A (GB)
Title: A process for the preparation of liquid hydrocarbon mixtures having a high octane number
IPC: C10G59/04
Filed: 1958-01-28
Abstract: High octane gasolines are prepared by catalytically reforming a gasoline or fraction thereof in the presence of hydrogen followed by thermally reforming the reaction mixture without previous complete or partial separation of hydrogen or any other component and at the same pressure as the catalytic reforming. The starting gasoline should boil within the range 30 DEG  to 205-235 DEG  C. and is preferably a straightrun naphtha boiling in the range 93-190 DEG  C.  Gasolines obtained by thermal or catalytic cracking may be used but olefinic components should be hydrogenated before use.  Paraffins such as normal butane, pentane or hexane may be added.  The feed may be freed of sulphur and nitrogen if necessary.  Reforming catalysts include one or more metals of Group VI and/or VIII as metals, sulphides or oxides and may be supported on alumina.  Preferred are molybdena and/or chromia supported on alumina or 0.1-2% platinum supported on an acidic alumina support, e.g. containing silica, boron oxide, phosphoric acid or 0.1-2% fluorine and/or chlorine.  Conditions generally are 420-560 DEG  C. and a hydrogen partial pressure of 6-50 atmospheres gauge.  Fixed, moving or fluidized beds of catalyst can be used in a heated vessel or in a series of unheated reactors with intermediate heating.  The thermal reforming may be carried out at 500-700 DEG  C.  Residence time depends on the temperature and degree of conversion required but may be, for example, 8 seconds at 600 DEG C. or 3 seconds at 615 DEG  C. for 80% cracking of octanes present. Gases are separated from the liquid product and recycled but olefinic constituents are preferably first hydrogenated, e.g. over a cobalt oxide-molybdena-alumina catalyst; this may be done before or after the gas is mixed with p  the gasoline feed.  High-boiling components and those boiling below butene or pentane may be removed from the product by distillation.  It may be blended with other gasolines such as straightrun, cracked or thermally or catalytically reformed gasolines or fractions thereof, polymerizate or alkylate gasolines, isomerized light hydrocarbon fractions, isopentane or butane.  It may be improved by adding tetraethyl lead and antioxidants. Specifications 600,471, 665,618, 742,769 and U.S.A. Specifications 2,143,472 and 2,490,287 are referred to.

A pair of leads are severed from the lead lengths 24 along a plane 34 and the insulation of the wire is severed along planes 36, 38, by a cutting and stripping mechanism 14. A platform 28 of the feed mechanism 16 and a transfer mechanism 100 are moved simultaneously away from the mechanism 14, Fig. 2 (not shown), thereby stripping the covered insulation from the wire ends. Meanwhile wire measuring mechanisms 10 measure further lead lengths 24. The feed mechanisms 16 are swung round to present the stripped ends of the lead lengths 24 to a terminal applicator 12, Fig. 3 (not shown), and simultaneously the transfer mechanism 100 is swung round to dispose the stripped ends of the leads between the jaws of a clamping assembly 212 mounted on the conveyer 200. Terminals T are applied by the applicator 12 and then the jaws of the assembly 212 are closed while simultaneously the jaws of a further assembly 212 at the other end of the conveyer are opened to release completed leads into a container 22 and the devices 18, 20 crimp terminals T1 to the ends of leads 29. The conveyer is then advanced one step, the feed mechanism 16 and the transfer mechanism 100 are swung back to their original positions and the work cycle repeated. The various operations in the work cycle may be synchronized by the use of a common cam-shaft and/or by electronic means. Further means may be provided downstream of the applicator 20, e.g. for forming the leads into an electrical harness or for applying insulating housings to the terminals.
