Abstract: 956,511. Heat-insulation tubes. PARK SECTIONAL INSULATING CO. Ltd. Feb. 8, 1963 [Feb. 19, 1962], No. 6403/62. Heading F2P. [Also in Division B5] An insulating covering for pipes, containers, furnaces &c. comprises a layer of asbestos wool impregnated with a hardenable adhesive which forms an outer skin, and an inner layer of fibrous mineral material such as mineral, glass or slag wool or fibres bonded thereto by the adhesive which is coated on both faces of the inner layer. The adhesive may be aqueous sodium silicate solution or a thermosetting resin. The covering may be in the form of slabs but is preferably in the form of a semicylinder, or a cylinder cut almost through diametrically, leaving the asbestos layer on one side to act as a hinge. The semi-cylinder comprises the outer asbestos wool layer 1 and inner fibrous layer 2, and is made by superposing the fibrous layers the inner of which has been coated with the adhesive on both sides, wrapping the layers around a mandrel covered with mica 4 as a parting agent, securing them by end collars, and pressing the cylinder so formed, while rotating it on a pair of rollers rotating in the same direction, by means of an upper pressing roller. The product, which has a hard outer skin due to distribution of adhesive, is dried, the mandrel removed, and the cylinder sawn through wholly or partly as above. The asbestos wool layer may be pre -impregnated with adhesive. In a modification, the impregnated layers are placed in a mould, a former dusted with mica pressed against them, and the whole oven-dried.

IPC: C07C17/00
Filed: 1959-02-26
Abstract: Catalyst-solvent combinations for isomerizing or polymerizing fluorine-containing olefines (see Group IV(b)) comprise (a) a halide or hydroxide of a Group I metal (including copper, silver and gold), or methanol, as the catalyst, and an N,N-dialkylamide, N,N-dialkylaniline or dialkylsulphoxide as solvent, or (b) a quaternary ammonium salt R4NX, where R is a hydrocarbon radical and X is an anion, as catalyst and a hydrocarbon, N,N-dialkylamine or N,N-dialkylamide as solvent.  In examples using various catalyst-solvent combinations, the catalyst is NaBr, NaCl, NaF, KBr, NaHF2, NaBr, methanol, tetramethylammonium chloride, KHF2, dilauryldimethylammonium chloride, benzyltrimethylammonium hydroxide or sodium hydroxide; and the solvent is dimethylformamide, dimethylsulphoxide, dimethylaniline, benzene, or cyclohexane.ALSO:A perfluoro olefine or omega-hydroperfluoro olefine having at least three carbon atoms is converted into a thermodynamically more stable isomeric form (which may be a polymer of the initial compound) by contacting it at 0-200 DEG C. with a catalyst-solvent combination, liquid under reaction conditions, which comprises (a) a halide or hydroxide of a Group I metal, or methanol, as the catalyst and an N,N-dialkylamide, N,N-dialkylaniline, or dialkylsulphoxide as solvent; or (b) a quaternary ammonium salt R4NX, where R is a hydrocarbon radical and X is an anion, as catalyst, and a hydrocarbon, N,N-dialkylamine or N,N-dialkylamide as solvent.  The process converts terminally unsaturated perfluoro olefines and omega-hydroperfluoro olefines into the isomeric internally unsaturated perfluoro olefines and 1-hydroperfluoro olefines respectively.  The invention also comprises internally mono-unsaturated acyclic perfluoro olefines having the carbon skeleton <FORM:0910371/IV (b)/1> or <FORM:0910371/IV (b)/2> which compounds are prepared by the polymerization of hexafluoropropylene by the process of the invention.  In Examples, (1) and (5) hexafluoro propylene is converted into a mixture of perfluoro-4-methylpentene-2, perfluoro-2-methylpentene - 2, perfluoro-2,3,5-trimethylhexene-3, perfluoro - 2,3,5 - trimethylhexene-2 and perfluoro-2,4,5-trimethylhexene-2; (2) perfluoro2,3,5-trimethylhexene-3 is partially converted into perfluoro-2,4,5-trimethylhexene-2 and perfluoro-2,3,5-trimethylhexene-2; (3) perfluoro-4-methylpentene-2 is converted into perfluoro-2-methylpentene-2; and (4) 8-hydroperfluorooctene-1 is converted into 1-hydroperfluorooctene-1.

Abstract: 1,144,095. Injection moulding machines. DESMA-WERKS G.m.b.H. 14 Feb., 1967 [19 Feb., 1966; 17 Dec., 1966], No. 6904/67. Heading B5A. [Also in Division A3] In an injection moulding apparatus comprising a mould having a movable plunger 54 for varying the size of the mould cavity, movement of the plunger into a forward position for reducing the size of the mould cavity is effected by one or more parts (e.g. thrust bolts 62 and/or an injection nozzle 11a) secured to an injection head 11. Movement of the plunger into a rearward position assisted by springs 55 permits expansion of the already injected material or injection of further material. The invention is applied to footwear incorporating dissimilar and/or differently coloured and/or foamed injectable materials. The first injection position is determined by interchangeable shims 58 and the second position by adjustable bolts 59. The upper 51 may also be formed by injection moulding and may include an integral first sole layer 52 and a lining (71), Fig. 4 (not shown). A layer (72) of foamed material may be provided with an outer layer (73) of compact material which may also be formed by injection. In Fig. 3 two (or more) mould covers 15, 16 are pivotable about an axis 23 by means of piston drives 27, 28. The cover 15 has a mould piece 20 which co-operates with the last 22 for injection moulding a first sole layer through a passage 46.

Title: Frequency control system
IPC: H03L7/00
Filed: 1949-03-14
Abstract: 665,686. Automatic frequency-control systems. SYLVANIA ELECTRIC PRODUCTS, Inc. March 14, 1949 [March 19, 1948], No. 6946/49. Class 38 (iv). An oscillation generator is automatically brought into fixed frequency relation with a second source by the normal mixing and discriminating circuits and the resulting error voltage is applied to a thermionic device for variably heating its anode and thereby adjusting a condenser to control the generator frequency. As shown, the second source which may comprise a receiving aerial feeds a mixer 12 which also receives the output of a local source 13 comprising a back-coupled valve circuit. The difference-frequency is fed through one or more stages 14 to a discriminator 15 and rectifiers 69, and the error voltage across the rectifier load resistors 73, 74 is fed through a smoothing circuit 90, 91 to the grid of a valve 18. This may be of the form described in Specification 664,523, [Group XXXVI], in which the anode is a bimetallic strip 81 which flexes under thermionic bombardment and varies the capacity between itself and a back-plate 80, forming a variable condenser connected in series with a further condenser 88 across the tuned circuit 31 of the oscillator 13. A radio receiver is thus brought automatically into tune with an incoming wave. A similar circuit may be used for maintaining an unstabilized transmitting oscillator at a fixed frequency separation from a standard oscillator, Fig. 2 (not shown).

Abstract: 831,773. Ventilating. CARRIER ENGINEERING CO. Ltd. March 5, 1958 [April 2, 1957], No. 7100/58. Class 137 [Also in Group XXXV] An air conditioning system allowing cooling of an enclosure by means of either air from outside through duct 33 or recirculated air through duct 32 which is drawn by fan 15 and delivered to the enclosure, has a selector switch 17 with a "winter" or "ventilate" position as shown, and a "summer" or "cool" position in which contacts 18, 19 and 20 are connected. In the "winter" position, a bulb 29 in the enclosure and bellows 30 act at a predetermined upper temperature limit to complete a circuit from contact 19 through a heater 24 in bellows 27, contact 27<SP>1</SP> and compressor 10 and fan 14 of refrigerator; the current is insufficient to operate the refrigerator but causes the bellows 27 to expand and through linkage 39-41 moves a plate 35 to open duct 33 to duct 34, and close off duct 32, thus changing from an air recirculation system to replacement by cooler outside air until the temperature sensed by bulb 29 falls again. In the "summer" position heater 24 is short-circuited so that plate 35 permanently closes duct 33 to allow recirculation only, and compressor 10 and fan 14 are brought into action at the upper temperature limit, the fan 15 then blowing air over the evaporator 13 of the refrigerator into the enclosure. A lever 45 allows over-riding manual control of the damper plate 35, and is desired a temperature-sensitive bulb in duct 34 may be arranged to break the circuit through heater 24 at a predetermined minimum temperature to cause cycling of the plate 35 and obtain a relatively constant minimum temperature (say 50F.) of air delivered to the enclosure.
