Abstract: 939,001. Supply systems for heating resistors. SATCHWELL CONTROLS Ltd. Dec. 21, 1961 [Jan. 3, 1961], No. 269/61. Class 38 (4). A system for supplying two loads comprises means whereby, after a given period from switching on, one of the loads is switched out of circuit. As described the two loads comprise two heating elements 12, 18 of an electric hotplate, initial movement of a control knob 5 causing contacts 6, 7 and 10, 11 to close whereby the element 12 is supplied in a series circuit with the heater 9 associated with the contacts 6, 7 whilst the element 18 in series with normally closed contacts 13, 15 form a circuit in parallel therewith. A heater 17 is associated with the contacts 13, 15 and when a predetermined period from switching on has elapsed the contacts 13, 15 open to remove the supply from the element 18 whilst the heater 9 causes the contacts 6, 7 to cycle, the ON-OFF ratio being determined by the control knob 5. Thus rapid initial heating of the hotplate is effected. Alternatively the contact 13 may be connected to contact 6 so that the cycling of contacts 6, 7 do not control the supply to the heater 18. In another embodiment a fourth switch, operated by the control knob 5, is provided in series with the element 18, the contacts closing only when the control knob 5 is moved to the full heat position.

Abstract: A lubricating composition comprises a mineral oil and a minor proportion of a mixture of an oil-soluble metallo hydrocarbon sulphonate, an oil soluble phosphorized- and sulphurized-dicyclic terpene, and an oil soluble sulphurized-mono-cyclic terpene.  The metallo hydrocarbon sulphonate may be obtained by sulphonating wax-alkylated aromatic hydrocarbons and forming neutral or basic salts thereof having the general formula (wax) n-R-SO3-M-X, where n is 1 to 4, R is an aromatic hydrocarbon radical such as phenyl, tolyl, xylyl, cumyl, naphthyl or diphenyl, M is a divalent metal such as zinc, magnesium, calcium, strontium or barium, and x is -SO3-R-(wax)n or OH.  The wax substituents consist of hydrocarbon waxes, such as paraffin waxes or cerese waxes, having at least 18 carbon atoms in the shortest carbon chain and derive from hydrocarbon waxes having melting points varying from 90 DEG F. to 180 DEG F. Examples are <FORM:0716562/III/1> and <FORM:0716562/III/2> specific examples being the basic barium, neutral barium, basic magnesium, neutral magnesium, basic calcium, neutral calcium, strontium and zinc salts of di-wax-alkylated benzene sulphonic acid, the basic barium salt of a di-wax-alkylated naphthalene sulphonic acid, the barium salt of a petroleum oil sulphonate. The sulphonate may be in an amount of 0.1 to 10 per cent., preferably 0.4 to 5 per cent. by weight of the oil base.  The sulphurized- and phosphorized-dicyclic terpene may be obtained by reacting a dicyclic terpene such as pinene, camphene, fenchene and similar terpenes having one double bond and comprising two ring systems, with a phosphorus sulphide at a temperature of 100 DEG  to 160 DEG C.  The sulphurized- and phosphorized-dicyclic terpene may be in a concentration of 0.05 to 3 per cent., preferably 0.1 to 1 per cent., by weight of oil base.  The sulphurized-monocyclic terpene may be prepared by sulphurizing dipentene, terpinolene, limonene, sylvestrene and carvestrene and may be in a concentration of 0.05 to 2 per cent. preferably 0.1 to 0.5 per cent. by weight of the oil base.

Abstract: 547,155. Purifying hydrogen & other gases. POWER - GAS CORPORATION, Ltd., and MILNER, G. Jan. 13, 1941, Nos. 439 and 9876. Drawing to Specification. [Class 90] Hot gases, e.g. hydrogen produced by the steam-iron process or the reducing gases used in that process, which contain both carbon dioxide and hydrogen sulphide as impurities are purified by cooling them by dilute aqueous carbonate e.g. of an alkali or ammonia or an organic base, and simultaneously removing the hydrogen sulphide by warm liquid. The resulting liquor may be cooled and aerated to oxidize the sulphide to sulphate, thiosulphate and possibly free sulphur without liberation of substantial quantities of hydrogen sulphide. The carbonate solution may be produced in a second stage of a purification process which consists in absorbing carbon dioxide and hydrogen sulphide by aqueous alkali hydroxide, the carbonate thus produced being used in the first stage which is as described above. Cooling and aerating may take place between the second and third stages.

Title: Process for the preparation of crimped split fiber
IPC: B29C48/10
Filed: 1966-01-06
Abstract: 1,132,641. Crimped filaments from split film; laminates. POLYMER PROCESSING RESEARCH INSTITUTE Ltd. 6 Jan., 1966 [24 Aug., 1965], No. 634/66. Headings B5B and B5N. [Also in Division B2] Crimped fibres are produced by longitudinally stretching and then splitting film the front and back surfaces of which have different heat-shrinking properties and heat treating the resulting fibres. The differential shrinking properties may be obtained by laminating two films of different chemical composition or by using film of different degrees of orientation back and front. The composite film may be obtained by calendering preformed films, melt coating a preformed film or extruding flat or tubular laminated film, preformed film being partially stretched, if necessary, before coating or laminating. Splitting of the film may be by mechanical working as in Specification 1,084,390. The final fibres have a square or rectangular section. In examples: (1) polyacrylonitrile film and film from a copolymer of acrylonitrile and methyl acrylate (both made from solution) are laminated by calendering and the laminate stretched eight times at 97 C. and then fibrillated. The fibres are then heat shrunk at 100 C. in steam to produce crimps. (2) Partially oriented and non-oriented high density polyethylene film are laminated by calendering, split into tapes, the tapes stretched eight times in steam at 105 C. and split and the resulting fibres heat shrunk at 100 C. (3) Similar to (2) but the partially oriented film being melt coated with polyethylene. (4) Polyvinyl chloride film is solution coated with a vinyl chloride acrylonitrile copolymer, the resulting binary film slit into tapes and stretched six times at 105 C. in steam and split into fibres which are heat shrunk at 75 C. (5) Laminated film from two polyethylenes of different density is made by inflating a tubular extrusion and slitting. The resulting tape is stretched six times at 105 C. in steam, split, and the resulting fibres dry heat shrunk at 100C. (6) Polyethylene and polypropylene films are laminated by calendering, slit into tape, stretched 8 times in saturated steam at 115 C. and split in fibres. The fibres are dry heat shrunk at 105 C.
