Title: Improvements in or relating to the knitting of stocking toes on circular knitting machines
IPC: D04B9/46
Filed: 1969-06-23
Abstract: 1,241,716. Knitting. OFFICINE MONCENISIO GIA ANONIMA BAUCHIERO. 23 June, 1969 [5 Sept., 1968; 1 Feb., 1969], No. 31638/69. Headings D1C and D1K. A stocking toe closure is formed on a circular machine by gradual introduction of the full complement of needles during continuous rotary knitting and pulling the leading end of yarn to close the disc thereby formed. When the yarn guide 7 becomes operative the yarn is taken by the first needle past a hook 24 mounted on a slide and initially disposed within the needle circle. The hook is withdrawn against the action of spring 9 by means of a counter-weight in cylinder 36 when its fluid pressure support is removed. The thread is clamped by means 37. The first course 10 is taken by spaced needles, e.g. a, b and further spaced needles f introduced at the second course. A few courses are knitted between each subsequent introduction until knitting is proceeding on the full needle complement. When the closure has been knitted a roller 47 is lowered to engage the yarn held by the hook and tighten the first course. The yarn is seared and the end romoved pneumatically. The closure may itself comprise the shaped toe end of the stocking or be followed by a reciprocatory knit toe-the closure being above or below the foot. The closure may be knitted of different yarn to that of the remainder of the stocking.

Title: Fluorine substituted hydrocarbon copolymers
IPC: C08F214/26
Filed: 1965-07-26
Abstract: Terpolymers of vinylidene fluoride, 1 H-pentafluoropropylene and tetrafluoroethylene may be prepared by copolymerizing the monomers at 0 DEG  to 150 DEG  C. and 1 to 200 atmospheres in the presence of a free radical yielding initiator.  The polymerization may be effected in bulk, suspension, emulsion or solution, e.g. in halogenated and perhalogenated alkanes and cycloalkanes, and perfluoropropyl pyrane. In aqueous media emulsifiers, e.g. alkali metal and ammonium salts of fatty acids and perfluorinated, w-hydroperfluorinated or w-chloroperfluorinated acids, and buffers, e.g. sodium borate and sodium phosphates, may be present. Specified initiators are azo compounds, organic peroxides and hydroperoxides, peracids, peresters, hydrogen, sodium and barium peroxides, and salts of inorganic peracids, optionally together with activators, e.g. heavy metal salts, sodium bisulphite, metabisulphite and thiosulphate, and reducing sugars.  Chain transfer agents, e.g. mercaptans, alcohols and halogenated hydrocarbons, may also be used.  The products may be compounded with fillers, pigments, plasticizers and acid acceptors, and may be vulcanized with hexamethylenediamine, hexamethylenediamine carbamate, N,N1-bis-cinnamylidenehexamethylene diamine and diethylene triamine, or cured with benzoyl peroxide or high energy radiation. The products may be used in the manufacture of films, fibres, tapes, coatings, tubes gaskets, seals and containers. In examples vinylidene fluoride, 1 H-pentafluoropropylene and tetrafluoroethylene are copolymerized in aqueous media in the presence of (1 and 2) ammonium persulphate and disodium phosphate, (3) potassium persulphate and disodium phosphate, (4) ammonium persulphate, disodium phosphate and ammonium perfluorooctanoate, and (7) ammonium persulphate, ferrous sulphate and methanol; in perfluorocyclobutane in the presence of (5) perfluorobutyric anhydride and hydrogen peroxide; and in bulk in the presence of (6) benzoyl peroxide or azodiisobutyronitrile.  The products are compounded with magnesium oxide and carbon black and vulcanized with N,N1 - bis - cinnamylidenehexamethylene diamine.

Abstract: 1,136,653. Making combustible gas; reforming naphtha. BRITISH PETROLEUM CO. Ltd. 13 July, 1967 [15 July, 1966], No. 31816/66. Heading C5E. An aromatic-rich gasoline and a town's gas are made from naphtha as follows: the naphtha is preheated in a furnace and passed over a Pt group metal catalyst to increase its aromatic content; an H 2 -rich gas is separated from the gasoline in a high pressure separator and the gasoline is stabilized in a low pressure separator from which an overhead stream comprising C 3  and lower hydrocarbons with dissolved H 2  is removed; the gasoline is recovered, and part at least of the H 2 -rich gas is blended with furnace flue gas and/or the C 3  fraction of the overhead stream to give a town's gas of appropriate calorific value. The C 3  fraction is separated from the overhead stream by distillation. The catalytic stage is conventional and includes gas recycling, so that some hydrocracking may occur, and a halogen may be contained in the catalyst. The H 2 -rich gas may be used to compress the flue gas by driving a turbo-compressor.

Title: Improvements in or relating to the detection and/or registration of non-liquid particles in a stream of liquid
IPC: B29C48/92
Filed: 1961-09-08
Abstract: <PICT:0911618/IV(a)/1> In a method of counting and detecting particles in a liquid stream (see Groups XIX and XL(b)) only those particles possessing birefringent properties are used.  The invention is applied to the "artificial fibre" industry, the liquid under test being viscose.  As shown viscose from the main supply 44 is pumped at a known rate through the glass capillary 4.  Light from the source 1, polarized in the direction shown by the filter 3 is passed through the capillary 4, through a slit aperture 5 and through the polarizing filter 6.  Any light remaining is received by the photomultiplier 8 as a series of pulses corresponding in amplitude, length and number to the birefringent particles in the viscose.  Amplifiers 28, 29 and 30 supply the output of the photomultiplier 8 to a pen recorder 31 sensitive to both size and number of the output pulses and to an integrating recorder 135 arranged to receive only those pulses having a predetermined amplitude, i.e. those corresponding to the largest particles in the viscose.

Title: Method of compressing Gases
IPC: F04D25/00
Filed: 1968-07-08
Abstract: 1,192,327. Centrifugal and axial-flow compressors. CHEMICAL CONSTRUCTION CORP. July 8, 1968 [July 10, 1967], No.32569/68. Heading F1C. In a method of compressing a gas containing a quantity of CO by a centrifugal or axial-flow compressor having carbon steel parts exposed to the gas, a quantity of oil, e.g. hydrocarbon, mineral or silicone oil, is injected into the gas at a location upstream of the compressor. During compression the oil forms a protective coating over the gasexposed compressor parts to resist attack of the carbon steel by the CO. In the system shown there are two compressors 4, 15 and two oil delivery lines 2, 23. Moreover, water-cooled coolers 10, 18 and cyclone separators 12, 20 for removing the oil and condensed water vapour from the gas, are provided. The line 23 and separator 12, or just the line 23, may be omitted. The compressor 15 may be omitted in which case the cooler 10 may be omitted. The two compressors are driven by a respective or, as shown, by a common steam or gas turbine unit 6 or an electric motor unit, or by a number of drive units. The injected oil also provides lubrication for the rotary and support elements of the compressor. More than two compressors may be arranged in series or in parallel or both. In connection with a given example for which temperatures and pressures of the gas and quantities of oil and water present at various locations in the shown system are tabulated, it is stated that the gas is further compressed by two further series - connected compressors, and that oil is injected upstream of only the first of these further compressors.

Motor power plant.-Relates to turbo-generator installations for steam-driven vehicles, wherein a main group comprising a turbine 1 and a polyphase generator 2 supplies current to the driving- motors of the vehicle, and an auxiliary group comprising a turbine 3 and a direct-current generator 4 generates the exciting-current for the main group as well as the current for the auxiliary machines. The valves 6, 7 of the two turbines are so controlled that the main group cannot be started until the auxiliary group is already running, and the auxiliary group cannot be stopped until after the main group is stopped. Thus, the vehicle is started by opening the valve 7 of the auxiliary turbine, Fig. 2, by hand, whereupon oil pressure is delivered by a pipe 9, Fig. 3, to the upper side of a piston 10, and the valve 6 of the main turbine is opened against the pressure of a spring 11. Both main and auxiliary groups have their own oil-pumps, but the pipe circuits are inter-connected. The valve 7, Fig. 2, cannot be closed until after the cock 12 has shut off the oil from the pipe 9 and piston 10 of the valve 6, whereupon the hand-wheel 8 of the valve 7 can be brought into the closing position.
