Abstract: 250,215. Viet, P. April 4, 1925, [Convention date]. Spray carburettors.-Combustible mixture for starting an engine, is supplied by means of an auxiliary spray carburettor 13 supplied with air by a compressor 2 and connected to the engine cylinders bv a distributing valve. The compressor 2 may be driven by an auxiliary internal-combustion engine. 1 In one form, Fig. 1, a singlestage compressor 2 is connected through an air reservoir 10 and a cock 5 to the space around the fuel nozzle 13 and also to the space above the fuel in the container 12, which has an inlet 15 and overflow 16 controlled by a cock 17, or may have a float-controlled inlet valve. The cocks 5, 17 may be connected so that one is open when the other is closed, and vice versa. The outlet from the carburettor is connected to a rotary distributing valve mounted upon the engine. In modifications, Fig. 6 and 8, the carburettor and the distributing valve 26 are both mounted on the engine and are connected to the compressor by a pipe provided with a valve. In further forms, a two stage compressor is employed, having a stepped piston and cylinder, two cylinders side by side, or two cylinders in tandem. The highpressure stage is connected to the space around the fuel nozzle of the carburettor and the lowpressure stage to the float chamber and to the space around a second nozzle surrounding the fuel nozzle.

Abstract: A textile thread-guide (which may be a pig-tail, lease-rod, or of the double-disc type) is provided with an abrasion-resistant layer by flame-spraying on to the surface of the guide a layer of material which is then made smooth.  The material may be metallic or non-metallic; chromium steel, tungsten carbide and ceramics containing a major proportion of an oxide of aluminium, zirconium or titanium are mentioned.

Abstract: 1,131,786. Metal-containing aminoplasts as olefin polymerization catalysts. SOLVAY & CIE. 21 Feb., 1967 [24 Feb., 1966], No. 8212/67. Headings C3P and C3R. An olefin polymerization catalyst is obtained by treating an aminoplast having free methylol groups with a compound of a metal of Group IVA, VA or VIA of the Periodic Table, which compound reacts with the methylol groups so as to give a product in which metallic radicals are bound by at least one valency to methylol residues and have at least one valency not so bound. Suitable aminoplasts are urea-formaldehyde and melamine-formaldehyde condensates; suitable metal compounds include the halides, alkoxy-halides and alkoxides, e.g. TiCl 4 , Ti(OEt) 3 Cl, VOCl 3 , VCl 5 , and VO(OBu) 3 . The catalyst is activated by means of a hydride, organometallic compound or elemental metal of Group I, II or III of the Periodic Table e.g. a trialkyl aluminium or an alkyl aluminium halide. The catalyst is suitable for polymerization and copolymerization of ethylene, propylene and butylene. In Examples a melamine-formaldehyde resin or urea-formaldehyde resin is treated with excess pure TiCl 4  or VQCl 3 -TiCl 4  mixture; the products, activated with tri-isobutyl aluminium, are used to polymerize ethylene or propylene in hexane, or an ethylene-propylene mixture without solvent. A composition is prepared containing the elastomeric copolymer of ethylene-propylene of Example 3, 50 p.h.r. of HAF carbon black, 5 p.h.r. of dicumyl peroxide and 0À5 p.h.r. of sulphur, and is vulcanized.
