Title: Improvements in and relating to composite fabrics
Inventor: BOYD JOHN
IPC: B32B27/00
Filed: 1956-02-29
Abstract: 805,309. Composite fabrics; knitted fabrics. COURTAULDS, Ltd. Feb. 27, 1957 [Feb. 29, 1956], No. 6292/56. Classes 74 (2) and 140. [Also in Group IX] A composite fabric for use as cloth or apparel for protection of objects and persons against acid or alkali comprises outer layers of fabric woven or knitted essentially from polyacrylonitrile or polythene threads and an interlayer of loose staple fibres resistant to acid or alkali or both, the layers being secured together, by stitching or thermal bonds spaced at least 0.5 inch apart, so as to preserve the vapour permeability of the fabric. The interlayer fibres are preferably of polythene, polystyrene or polyacrylonitrile. Instead of polyacrylonitrile threads and fibres copolymers containing not less than 80 per cent of acrylonitrile may be used, for example a copolymer containing 93 per cent of acrylonitrile and 7 per cent methyl acrylate. The securing means may comprise rows of stitches of acid or alkali-resistant thread such as polythene spaced about one inch apart across the fabric, or the fabric may be heat pressed along similarly spaced lines or heat bonded in random spots. In an example, upper and lower 3/1 twill fabrics of polythene yarns, heat stabilized at 65-70‹ C. and comprising respectively 156 warp and 58 weft threads per inch of 0.005 inch yarn and 124 warp and 49 weft threads per inch of 0.0075 inch yarn, enclose a loose web of fibres of polythene or the copolymer mentioned above about 0.015 inch thick and weighing about 3¥oz. per square yard, the fibres varying in length and diameter but having a mean diameter of 4-5 microns. The assembly is secured by rows of polythene stitches about one inch apart across the fabric. Specification 471,590, [Group IV], is referred to.

Abstract: 142,602. Whitaker, J., and Whitaker, R. March 14, 1919. Addition to 101,060. Circulating or passing liquids through materials. - An improved lifting-gear is provided for the hinged inner chamber of the apparatus described in the parent Specifications, consisting of an upwardly projecting screw shaft at each end of the chamber, rotated by a power shaft and having swivel-nut and lever-arm connexions to the chamber, which is thereby lifted from each end instead of from the middle. The tipping is controlled from a power shaft A, Fig. 1, mounted in trunnion bearings K behind the vat B. The hinge pin or shaft C of the inner chamber carries arms D each provided with a double bracket E attached to a beam F on the inner chamber, and a. swivel nut H engaging an upwardly-extending screw shaft I geared to the shaft A through bevel planet-wheels. As the shafts I are rotated, the inner chamber is thus raised. The solid shafts I may be reduced in length and fitted with hollow externally-screwed shafts L, Fig. 4, splined thereon. The solid shafts I carry nuts N which support the hollow shafts L, and these engage the swivel nuts on the brackets E. Side extensions O of the nuts N engage a guide-rod P to prevent their rotation.

Title: Resistors and method of making the same
IPC: H01C17/02
Filed: 1954-03-05
Abstract: 748,111. Casings and enclosures for resistance elements. ERIE RESISTOR CORPORATION. March 5, 1954 [March 25, 1953], No. 6538/54. Class 37. [Also in Group V] A resistance element with connecting leads is sandwiched between plastic sheets and the latter are joined together by a moulding process. In the example of Figs. 1-2 the plastic casing 1 formed by moulding together plastic sheets 7, 8 encloses resistance strip 5 and transverse connecting leads 2, 3. In a second embodiment, Figs. 4-5, the leads 9, 10 are lengthwise the resistance strip 5. The plastic sheets 7, 8 may consist of felt-like paper fibres impregnated with uncured or partially cured phenolic resin. The resistance strip 5 is shown to be a carbon/plastic or other resistance film or coating 5 (liquid or powder) on a fibrous tape 4 but may comprise a self-supporting carbon/plastic composition strip. The resistance film 5 is overcoated with terminal layers 6 of conductive paste (e.g. metallic particles in resin binder) and the connecting leads where they contact the terminal layers 6 are coated with " Aquadag " (Registered Trade Mark) or similar colloidal graphite composition. The plastic casing 1 has projections, as e.g. at 9a, 10a in Fig. 4, above and below the connecting leads so as to minimize distortion of the resistance strip during moulding. The invention is directed towards quantity production of both Figs. 1-2 and Figs. 4-5 resistors by conveyer technique. The resistor of Figs. 1-2 is manufactured (see Figs. 8-6) by using as conveyer spaced wires 11, 12 which are subsequently to form the leads 2, 3. At spaced intervals the resistance strip with registering plastic sheets 7, 8 are brought into contact with each other and the wires and are cured between hinged mould sections 13, Fig. 8, which are pressed together by rolls 14. Before the wires 11, 12 are cut to form the leads 2, 3 the plastic casings may be passed over colour coating rolls 15. The resistor of Figs. 4-5 is manufactured (see Figs. 9-11) by using as conveyer plastic impregnated paper 18 unwinding from roll 17 and travelling below plastic impregnated paper 19 unwinding from roll 16. The resistance strips &c. are spaced along the paper 18 and the latter is joined to paper 19 by hinged mould sections 20, Fig. 11. After colour coating the moulded strip is cut into individual resistors. The connecting leads may have links, Fig. 12, or hooks, Fig. 13, in contact with terminal coatings 6.

Filed: 1963-02-19
Abstract: A uranium based alloy contains: .Mo.0.1-0.75 atomic per cent, .Cr.0.1-0.45 atomic per cent, the remainder, apart from incidental impurities, being uranium The alloy may be heat treated by heating at 700-900 DEG C. followed by continuous cooling at 100-250 DEG C. per minute.  If the heating is carried out in a salt bath, residual salt on the surface of the billet will prevent excessive oxidation while cooling in air.  For alloys in the following range: .Mo.0.25-0.75 atomic per cent, .Cr.0.2 -0.45 atomic per cent, .U.balance apart from impurities, a preferred heat treatment is heating at 710-730  DEG C. for 15-30 minutes, direct transfer to a soaking bath at 540-560 DEG C. where it is held for 15-30 minutes. The alloys may be prepared using uranium metal and 3-6% master alloys with uranium for Mo and Cr.  Specification 863,492 is referred to.

Abstract: 1,076,658. Protective arrangements. WILLING LUMI-NEON Ltd. Feb. 17, 1966 [Feb. 17, 1965], No. 6880/65. Heading H2K. A protective arrangement for an apparatus, e.g. an electric sign, supplied through a step-up mains transformer (9), comprises a current transformer (3) having its primary winding connected in series with the supply to the mains transformer and its secondary winding connected to the coil of a relay (7) having a first normally closed pair of contacts (2) and a second normally open pair of contacts (8) connected in parallel with each other and in series with the supply. When the supply is switched on and conditions are normal, the relay is energized and closes the second pair of contacts. It opens the first pair of contacts which thereafter remain open. Should the apparatus now fail, the reduction in the current causes the relay to release so that the second pair of contacts are opened and interrupt the supply to the mains transformer. A bridge rectifier may be connected between the current transformer and the relay. The first pair of contacts are closed manually and a third pair of contacts, connected in series with the second pair of contacts, may be opened in the event of overload.
