Title: Fluid pressure control mechanism
IPC: B64D15/20
Filed: 1944-07-17
Abstract: 584,804. Preventing and indicating ice-formation on aircraft. CLEVELAND, F. J. (Bendix-Westinghouse Automotive Air Brake Co.). July 17, 1944, No. 13647. [Class 4] An inflatable device 5 for breaking ice-formations upon an airfoil 4, and/or a warning or signalling device may be controlled by the pressure in a conduit 44 connected at one end to a compressed-air source 6 and at the other end to a plate 40, having therein an orifice 41 and being situated in the slip-stream of the airfoil. Normally an outward flow of air is maintained through orifice 41 ; when icing occurs so as to block the orifice, the pressure in conduit 44 rises, and passing through conduits 52, 53 under control of a governor 51 applies pressure in the control chamber 33 of a valve 16, which is thus opened to allow air from source 6 to pass through a reducing valve to the valve 16 and out from an outlet chamber 19, under control of a diaphragm 31 forming a wall of the control chamber 33, to conduit 10 leading to the inflatable boot 5. The pressure air to orifice 41 is first passed through an orifice 50, which is made smaller than orifice 41 so that the air-pressure in conduit 44 cannot rise appreciably above atmospheric pressure in non- icing conditions. In a modification, a signal lamp and a pressure gauge are connected to conduit 44, rise of pressure in which acts upon a switch to complete a battery circuit for the lamp and also for a de-icing distributor. In another modification the plate 40 with orifice 41 is made flexible so as to be pressed outwardly by rise of pressure in conduit 44 to break ice upon the plate; in order to prevent inward flexion of the plate 40 by the slip stream, stops are provided on the inner side of the plate.

Title: Improvements relating to oil filled transformers
Inventor: ANDREW PHILIP HOLMES
IPC: H01F27/14
Filed: 1962-04-10
Abstract: 955,211. Transformers. FERRANTI Ltd. March 29, 1963 [April 10, 1962], No. 13690/62. Heading H1T. To allow for the expansion of the oil during operation, the tank 1 of an oil-cooled transformer contains at least one gas-filled chamber 8, mounted in the tank 1, so as to be spaced from its inner surfaces each chamber opening into the tank (at 10) so that the oil may expand into the chamber without allowing any of the gas to escape. For cooling purposes the oil in the transformer, which is to be buried, is in contact with all the tank walls. The tank, which has a lid 2 and terminal housing 3, is elongated in plan (e.g. rhomboidal, Fig. 2, not shown) to present a large cooling surface. Each chamber, 8, may contain a sloping baffle plate 12 welded to its lower and side walls, so that as the oil expands during operation (the oil surface rising to 13) the surface area of the oil in contact with the gas in the chamber 8 decreases, reducing the absorption of gas by the hot oil. Instead of using a baffle plate 12 in each chamber, the aperture 10 may be circular and lead into a pipe up which the oil can expand, contact with the gas being reduced by a float on top of the oil in the pipe. The perforated plates 11 restrict the mixing of the oil in the chambers 8 and that in the main tank 1. In one embodiment, the tank (of rhomboidal plan) contains two triangular chambers 8, but in others only one or more than two, may be used. The gas used may be air.

Filed: 1965-03-31
Abstract: <PICT:1077095/C1/1> In a process for the production of sheet glass by the "floatation" technique, as described in Specificaion 1,019,757, the cooled ribbon is removed from the molten metal bath and tank and conveyed away whilst it is at least partially supported upon a cushion of gas.  In one embodiment, Fig 1, the glass ribbon 14 is removed from the molten metal bath 12 by take-out rolls 16, 18 and then passes into an annealing lehr 20.  Drapes 24, spring-loaded carbon blocks 27 and wall 29 restrict ingress of air and carry over from the molten metal tank.  The ribbon 14 is conveyed through the lehr on rollers 28.  To reduce the pressure of the ribbon 14 on the rollers 28 gaseous support means as described in Specifications 1,021,841, 1,021,843 and 1,021,846 (except that the rows of modules 32 are arranged at right-angles to the path of travel of the ribbon) are used.  In a modification, the modules are replaced by removable plenum chambers 100, having spaced openings 106 in the top thereof, inserted between adjacent rollers 28. A coating material may be included in the supporting gas.
Patent GB-495829-A (GB)
Title: Process for waterproofing textile materials
IPC: D06M15/263
Filed: 1937-05-18
Abstract: Textile materials are rendered water-repellent and resistant to creasing by impregnation with a mixed polymerizate obtained by common polymerization of maleic anhydride and a vinyl ester of a fatty acid having at least 12 carbon atoms in the molecule or a vinyl ether of an aliphatic alcohol having at least 12 carbon atoms in the molecule, and with an aldehyde or substance yielding an aldehyde or a soluble synthetic aldehyde resin or the components or a water-soluble precondensation product thereof, and drying the impregnated material. Instead of the mixed polymerizate, the free acid or a functional derivative other than the anhydride may be employed; alternatively, a mixed polymerizate obtained by common polymerization of a mono- or di-ester of maleic acid with an aliphatic alcohol containing at least 6 carbon atoms and a vinyl ester or ether may be employed. Crease-resisting agents specified are formaldehyde or hexamethylenetetramine; mixtures of formaldehyde and urea or of acetaldehyde and phenol and the condensation product of polyvinyl alcohol and formaldehyde; and dimethylol urea.  Impregnation with these substances may be performed in the presence of acids or compounds splitting off acid, e.g. tartaric, lactic, glycollic, acetic or formic acids, ammonium chloride or diethyl tartrate. The textiles may be impregnated with the two components successively, in either order, or simultaneously in a single bath; and may be subjected to a raised temperature during or after drying and after one or both impregnations where these are successive.  Tissues, yarns, or loose fibres of cotton, linen, staple fibre, wool, casein wool, and viscose, copper or acetate artificial silk, or mixed fabrics may be treated.  Examples are given of treatment of various materials successively, in baths containing the creaseproofing and waterproofing agents and vice versa; also of a single-bath treatment. In example (13) the crease-proofing agent comprises a solution obtained by heating 44 parts of polyvinyl alcohol for 30 minutes, at boiling temperature, with 440 parts of water, 1 part of formaldehyde and 1 part of hydrochloric acid, and finally adding 2,5-3 parts of sodium acetate and cooling.  The following mixed polymerizates are described in the examples: maleic anhydride with vinyl octadecyl ether, vinyl palmitic acid ester, vinyl dodecyl ether and vinyl tetradecyl ether; maleic acid di-octadecyl ester and vinyl octadecyl ether; vinyl stearate and maleic acid mono-octadecyl ester; maleic acid and vinyl laurate; the monomethyl ester from the mixed polymerizate of maleic anhydride and vinyl octadecyl ether; the free acid of the mixed polymerizates from maleic anhydride and vinyl octadecyl ether; and the pyridine salt of the free acid of the mixed polymerizate of maleic anhydride and vinyl dodecyl ether. Specification 464,860 is referred to.

Title: Method and apapratus for apolying a cover to a conduit
IPC: B29C51/00
Filed: 1974-03-29
Abstract: 1446132 Covering ducts JOHNS-MANVILLE CORP 29 March 1974 [4 April 1973] 13925/74 Heading F2P [Also in Division B8] Apparatus for applying a cover 44, e.g. of laminated material, having a major surface of a heat activated adhesive to a tubular duet includes a cover material supply station 22, cutter station 24, feed station 26 and wrapping and bonding station 28. Cover material is drawn from roll 36 by feed rolls 38, 40 and cut to predetermined lengths by chopper assembly 46, 48. The cover material 44 is fed to the wrapping and bonding station by means of endless belts 54 driven by motor 64 through magnetic clutch, drive belt and sheave assembly 66. The cover material is aligned and held in readiness prior to entering the wrapping and bonding station by means of retractable pins 70 activated by photocell 74 located between pins 70 and cutter station 24. The pins 70 also prevent more than one piece of cover material entering the wrapping and bonding station. The duct to be covered enters the wrapping and bonding station by means of a loading conveyor, including an endless chain 134 with spaced-apart pins 136 for engaging the duct, until it depresses contact plate 146 actuating switch 148 which stops the conveyor and raises the aligning pins 70 to permit the cover material to enter the wrapping and bonding station. The duct is supported by heated roller 76 and a smaller cold roll 78, having upper surfaces at the same level, driven by motor 82 through drive belt and sheave assemblies 84, 100. The rolls are movably mounted in parallel relationship to accommodate ducts of different diameters. The cover material 44 is fed by belts 54 between the heated roll 76 and the duct which are urged together by pressure applicator 80 including moving endless belt assembly 102. The pressure applicator 80 helps to rotate the duct and maintain it in a fixed position. The pressure exerted by the applicator 80 is adjustable by a pair of piston and cylinder assemblies 128 pivotally secured to support brackets 130 and frame members 124 attached to the endless belt assembly 102; the pressure applicator being pivotally mounted on shaft 110. Shaft 110 is mounted in bearings on adjustable support brackets 116 slidably mounted on vertical frame members 118 by means of threaded shafts 120 and collars 122, to accommodate different diameter ducts. The heated roll activates the adhesive and presses the cover against the duct thereby forming a bond. The cold roll which may be at ambient temperatures or cooled may serve to set the adhesive. After the cover has been applied to the duct the endless belts 54 of the feed station and 104 of the pressure applicator are stopped. Stoppage of belts 104 causes the continued rotation of the rolls 76 and 78 to eject the duct from the wrapping station. Control means then causes the pressure applicator to be raised, the photocell control to be reset and the loading conveyor to be started to bring a further duct into the wrapping and bonding station ready for the next cycle.

Title: Elastic fabrics comprising composite yarns
IPC: D03D15/56
Filed: 1964-04-07
Abstract: A method of manufacturing an elastic textile fabric, comprises the successive steps of twisting a single yarn made of a synthetic elastic and shrinkable material-e.g. spandex-assembling the elastic single yarn with a single yarn made of inextensible material by using an assembling twist of opposite sense to that of the elastic yarn to form a composite twisted yarn, manufacturing a textile fabric by using, at least in part, the composite yarn, and shrinking the elastic yarn by momentarily heating the textile fabric with steam up to the temperature producing total shrinkage without damage to the most fragile textile material employed in manufacture of the fabric. In examples the spandex yarn is twisted 650 or 2200 turns/metre and the inextensible yarn-which is a multifilament nylon yarn-200 or 650 turns/metre in the opposite direction, with in each case the assembling twist being 650 turns/metre.  The composite yarn is subjected to a slow thermal stabilization treatment which, together with the fabric steam treatment, is described in Specification 1,018,953.  The stabilized yarn, greased with a linseed oil base product, is made into a woven or knitted fabric.  The yarn may be alternated in the fabric with a similar yarn but of opposite twist, or with a non-elastic yarn, and, in a woven fabric, may comprise part or the whole of the warp and/or weft.  The non-elastic yarns may in an elastic crepe fabric be highly twisted yarns, yarns of high denier, or composite twisted yarns and in fabrics having a "foamy" appearance be slightly twisted yarns having a large number of filaments, or staple fibre yarns of polyacrylonitrile or natural fibres.  Elastic crepe fabrics of "foamy" appearance may be formed using the two types of non-elastic yarns.
