Abstract: 887,461. Sewing machines. FAIRWEATHER, H. G. C. (Singer Manufacturing Co.). Aug. 16, 1960, No. 28344/60. Class 112 In a zig-zag sewing machine the needle bar is mounted in a swinging gate pivoted on a rod adapted to be secured in angularly adjusted position in the machine frame, the portion of the rod carrying the gate having an axis offset from and parallel to the axis of the portion of the rod turnable in the machine frame, whereby the rod may be adjusted angularly to align the pivotal axis of the gate with the pivotal axis of a co-operating lockstitch looptaker. The vertical needlebar 8 is mounted in a gate 45 formed with lugs 47 pivoted on a central portion 48 of a vertical pivot rod. At the lower end of the latter is an enlarged head 52 pivoted in a lug 51 on the machine frame 4. A reduced portion 55 at the upper end of the rod is pivoted in a fixed lug 50. The axes of head 52 and portion 55 are aligned, and are offset from and parallel to the axis of portion 48. The pivot rod may be turned, by means of a screw-driver slot 60 in head 52, to align the axis of portion 48 with the axis of a vertical-axis oscillating hook. Screws 57 and 54 (not shown) are provided in the lugs 50 and 51 to lock the rod in adjusted position. The gate is oscillated by a pitman 61, the rear end of which carries a block abutting a plate through which the pitman passes. The front end of the pitman is fixed adjustably by a screw 64 to a bracket 62 pivoted on a pin 63 carried by the gate. A collar 58, fixed to portion 58 by a screw 59, abuts lug 47. A torsion spring 77, connected between collar 58 and the gate, biases the latter angularly to hold a follower element, associated with pitman 61, against a pattern cam.

Title: Improved process for the manufacture of fabrics for pneumatic tyres
Filed: 1926-11-11
Abstract: 262,743. Soc. du Latex. Dec. 11, 1925, [Convention date]. Fabrics composed of threads united by adhesives; coating materials in long lengths.-In making fabrics, particularly for tyres, composed of threads united by adhesives, the threads are fed to a coating apparatus in a number of layers passed through a reed in such a manner that one thread from each of the layers lies between the same two dents of the reed, the size and number of the dents being determined by the diameter of the thread and width of the fabric. The apparatus comprises a reed 2, Fig. 1, by which the threads 3 are separated into groups or sheets in which the threads lie in a vertical plane. These groups are then passed to a horizontal cylinder 10 upon which they are juxtaposed. Thence the web passes over a series of heated cylinders 11 and to impregnating rollers 4 in a bath of latex or aqueous suspension of rubber. After impregnation, the web passes over a drum 6 which may be heated, and then between drawing rollers 7, 7. When rubber dissolved in benzine or other solvent is used, it is introduced between the cylinders 8, 9 and 4, 12, Fig. 2, and the web is spread out on a suspension device to dry. A surface coating of rubber may then be given.

Title: Field effect transistor
IPC: H01L29/78
Filed: 1965-07-05
Abstract: 1,110,391. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 5 July, 1965 [31 July, 1964], No. 28411/65. Heading H1K. In an insulated gate field effect transistor insulating material associated with the gate electrode extends over the entire area between source and drain and has thinner and thicker parts opposite the portions of the channel adjacent the source and drain respectively, the gate electrode extending over the thinner portion. The thicker portion need have no metal coating, but it may be covered with a separate electrode or with an extension of the gate electrode. The separate electrode may be connected to the gate in operation or held at a different potential from the standing bias on the gate. The body of the transistor, of opposite conductivity type to the source and drain, may bear an electrode given a D.C. bias or used as an input for an auxiliary signal. Typical devices are constructed on a lightly doped P-type silicon body one face of which is polished and oxidized in steam, the oxide layer being used to form a mask through which phosphorus is diffused to form source and drain regions.. The remaining oxide is removed and the body heated in wet oxygen to grow a 4000 oxide film. The cooled body is heated in hydrogen to obtain the required channel characteristics. The oxide layer is removed over source and drain regions and photolithography and partial etching used to form steps in the oxide film over the channels. The parts near the source and drain regions may be respectively reduced to 2000 and left at 4000. Metal is deposited over the entire surface and etched away except from the region of the sources, drains, and stepped oxide over the channels. The body is divided into separate devices each of which is provided with leads (e.g. attached by thermo compression bonding) and encapsulated. The channel may be formed in single crystal material such as a silicon wafer or in an epitaxially deposited silicon layer. The gate insulation may be formed by thermal oxidation or applied by vapour deposition. Instead, the channel may be formed in polycrystalline material such as cadmium sulphide, cadmium selenide, or tellurium and the insulation may be deposited on the channel material. The latter may instead be vapour deposited on the insulation.

Abstract: 1,144,496. Desulphurizing aromatic feedstocks. BRITISH PETROLEUM CO. Ltd. 29 June, 1966 [7 July. 1965], No. 28768/65. Heading C5E. An aromatic feedstock is desulphurized in the presence of hydrogen by absorption on a supported nickel catalyst at a temperature and pressure at which the catalyst has desulphurization activity, but below that at which it has substantial hydrogenation activity and by progressive increase of the temperature and, if desired, the pressure, as the catalyst takes up sulphur, the operating conditions being such that no hydrogen sulphide is produced. The catalyst may be a nickel on sepiolite catalyst particularly that prepared and activated as disclosed in Specification 899,652 and comprising 1-50% by weight nickel. The feedstock may be benzene or a mixture of aromatic hydrocarbons and paraffins or naphthenes. The reaction temperature is progressively increased within the range 50-290‹ C. (122-554‹ F.) and the pressure within the range 0-2000 p.s.i.g.. the space velocity being 0À05-10 v./v./hr. The hydrogen may be supplied as commercially pure hydrogen or a gas containing 95 % hydrogen and the remainder methane, and introduced in a hydrogen: hydrocarbon mole ratio on total feed of 0-01- 0.5 :1. The presence of the hydrogen is said to inhibit deactivation of the catalyst. The process is effective to remove up to 10 p.p.m. sulphur and can be preceded by a preliminary hydro-desulphurization if required. In the example benzene is refined to a sulphur content of 0.6 p.p.m. by weight.

Patent GB-1092372-A (GB)
Title: Improvements in or relating to the manufacture of non-woven fabrics
Inventor: MEACOCK GRAHAM WALTER
IPC: D04H1/551
Filed: 1963-07-20
Abstract: A nonwoven fabric is made by segmentally bonding a fibrous web containing at least five per cent. of individually retractable or elongatable fibres and subjected to a treatment to effect such retraction or elongation to impart bulk to the unbonded areas. The fibrous web may be formed by carding, garnetting, air-laying and paper-making techniques for staple fibres whereas continuous filaments may be deposited with the aid of high-velocity turbulent fluid jets in random loopy manner on a suitable receiving surface. The segmental bonding may be achieved by dielectric welding as in Specification 1,092,373, or by applying a natural or synthetic resin from an engraved printing roll, or if the web contains thermoplastic fibres, bonding by applying heat and pressure using a heated embossed roller.  Retraction of the fibres may be effected by heating, e.g. by the application to the web of hot water, steam, air or other fluid at a temperature below the fusion temperature of the fibres, or by chemical action, e.g. of a mild acid or alkali, and may be accompanied by crimping of the fibres.  Fibres or filaments having two fibre-forming components, of which one has a higher shrinkage than the other; are particularly suitable and may be formed from polyamides, polyesters, polyesteramides, polysulphonamides, polyolefines, polyurethanes or combinations thereof.  The two components may lie side by side or in a sheath-and-core relationship in the filament. Other fibres which may be used include polyethylene terephthalate, which is retractable with accompanying crimping, various copolyamides, which shrink but do not crimp, and certain polyesters, polyurethanes and polyamides, which are elongatable. The web may also contain fibres whose length is not affected by the shrinking or elongating treatment.
