Patent GB-364757-A (GB)
Title: Manufacture of carbon from acetylene
IPC: C09C1/54
Filed: 1930-11-17
Abstract: Carbon is obtained from acetylene, or a gas containing the same, by mixing it with the vapour of a metal carbonyl and decomposing the mixture by exposure to a source of energy such as an electric spark or an incandescent filament.  The decomposition can be effected at normal temperature and pressure if the content of carbonyl, e.g. iron penta-carbonyl, exceed 0,8 per cent by volume.  The carbonyl may be evaporated in a chamber filled with acetylene and decomposed by electric ignition, the deposited carbon being removed prior to repetition.  The process may be made continuous by passing the acetylene through or over a liquid carbonyl and over a heated surface.  The heat produced may be used for preheating the incoming gas and the reaction may take place in a vessel of such large dimensions that the carbon is deposited only on the base thereof. Backfiring is prevented by passing the mixture of carbonyl and acetylene rapidly through narrow tubes which may be cooled. Vaporization of the carbonyl may be effected in an inert gas, e.g. nitrogen, mixture with the acetylene taking place just before the decomposition.  Two examples are given; in the first, intermittent decomposition is caused by an incandescent filament or a series of electric sparks and in the second, by a heated filament or by burning the gas leaving the reaction vessel.  After the decomposition has commenced, the flame may be extinguished and the hydrogen withdrawn from another aperture.  According to the Provisional Specification, ethylene or other gases which may take part in the reaction may be present and be decomposed.

Abstract: 430,142. Hose clamps. BORRESEN, H. A., 318, West Randolph Street, Chicago, U.S.A. Dec. 3, 1934, No. 34702. Convention date, Dec. 1, 1933. [Class 44] A hose clamp of sheet metal has an opening in one end through which the other end passes, the free end beyond the opening being turned up to form a flange to take a tightening-screw and the other end being cupped to receive the end of the screw. Fig. 1 shows a clamp made in two parts 10, 11, the narrower part 10 passing through an opening 13 in the wider part 11 which has a series of. bridge pieces 20, 21 to engage the hooked end 19 of the strip 10 to enable the clamp to be roughly adjusted to different sizes of hose. The bridge pieces are stamped up to allow of the inner surface of the junction to remain continuous. The end of the part 11 is bent up and screw-threaded to take a screw 12, the end of which engages a cupped end 14 on the strip 10. A part 15 stamped out from the hole 13 serves to reinforce the bent-up flange. In a modification the strip 10 has outwardly punched projections engaged by an inwardly directed hook on the part 11 to effect the coarse adjustment and the coned end of the screw projects through a hole in the cupped end of the part 10. Fig. 12 shows a clamp made from a single strip of metal cupped and apertured at its wider end. The narrower end has a series of holes 32 through one of which a screw 30 is passed and the end of the strip is bent over a round-edged nut 31. By making the wide end twice the width of the narrow end, two such strips can be stamped out with the greater part side by side as shown in Fig. 13.

Filed: 1956-11-16
Abstract: 807,938. Casting composite articles. SOC. D'ELECTRO-CHIMIE, D'ELECTRO-METALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. Nov. 16, 1956 [Nov. 19, 1955], No. 35171/56. Class 83 (1). A composite casting of two or more different steels or ferrous-alloys is made by casting steel or ferrous alloy into a mould containing a mass of a different steel or ferrous alloy, covered by a supernatant layer of liquid slag whose composition is such that at the melting point of the cast metal it has a low viscosity and a high interfacial tension with regard to said metal, and which is at a temperature considerably above said melting point, the temperature of the metallic mass being above the melting point of the slag, whereby the cast metal comes into contact with the metallic mass and progressively displaces the slag, and then allowing the cast metal and the metallic mass (if molten), to solidify. The metallic mass present in the mould may be solid or liquid, and may comprise two or more metals or alloys. To prevent erosion of the mass by the pouring of the next metal, an ingot mould has a sloping end wall B onto which the pouring jet impinges, and a sill S which is as thick as, or thicker than, the metallic mass already in the mould. The method may be performed by placing an ingot mould, small end up, in a larger mould, casting the first metal in the small mould, and progressively removing said mould as the ingot solidifies, pouring liquid slag into the large mould to cover the ingot, and then casting the second metal. Alternatively, the slag may be introduced before the small mould is removed. Specifications 789,657, 789,752, [Group XXXVII], 801,309 and 801,310 are referred to.

Abstract: 1,198,521. 5-Amino-isoxazoles. HOFFMAN LABORATORIES Inc., and CAMBRIDGE RESEARCH Inc. 1 Aug., 1967 [24 Aug., 1966], No. 35317/67. Heading C2C. 5-Aminoisoxazoles of the formula wherein R 1  and R 2  represent hydrogen or C 1-6  alkyl groups or alkoxy-substituted C 1-6  alkyl groups or together represent an optionally substituted alkylene radical, are prepared by reacting a halo-nitroso compound of the formula wherein Hal represents halogen, with an azamide ion. The reaction proceeds by displacement of the halogen by cyanide with simultaneous isomerization and ring closure and is preferably effected by refluxing in methanol or aqueous methanol using an alkali metal cyanide. The starting nitroso halide, which exists in a dimeric form, is prepared by reacting an olefin, R 1 -H = CH-R 2 , with a nitrosyl halide, e.g. nitrosyl chloride, preferably at ambient temperatures in an inert solvent using a molar excess of olefin. The crude product may be converted to the isoxazole without isolation. The 5-aminoisoxazoles may be converted, without isolation, to the corresponding 5-psulphanilylaminoisoxazoles by reaction with a p-acetamidobenzene sulphonyl halide and deacylation of the intermediate product. Examples describe the preparation of 3-chloro-2-nitrosobutane dimer and 5-amino-3,4-dimethylisoxazole.
