Patent GB-1116879-A (GB)
Title: Protective covering and article
Inventor: LANZA VINCENT LEONARD
IPC: B29C61/06
Filed: 1965-08-20
Abstract: A heat-recoverable member has a coating of a viscose flowable material applied to the surface and an anti-tack coating applied over at least a part of the surface of the said material not in contact with said member the coating being such that at the recovery temperature of the member it will dissolve in the material.  The member may possess the property of elastic memory and may be made of a cross-linked polymer which may have been cross-linked by the chemical means or by irradiation e.g. u.v. radiation.  The polymer may be a polyethylene or a co-polymer of ethylene and an alkyl acrylate, tetrafluoroethylene or vinyl polymers such as p.v.c.  The member may be tubular and may be preformed to expand or contract on recovery the interior or exterior surface or both may have the flowable viscous material applied thereto.  The member may be a tape which may be wrapped around a body to be protected.  The anti-tacke coating preferably covers the whole of the surface of the flowable viscous material. The coating may be of wax of m.p. 50-90 DEG C. and may comprise carnauba wax, wax-rosin mixtures, such as bees wax-rosin mixtures, ouricury, candelilla and palm waxes.  The flowable viscous material has a viscosity at room temperature sufficiently high to enable it, when contacted with the surface of the heat recoverable member, to remain in contact under normal gravitational forces. Materials having a viscosity of up to 1013 centipoises at 25 DEG C. have been found suitable.  Suitable materials are of a mastic type or a thixotropic, and it may be substantially non-crystalline such as a silicone or hydrocarbon grease, which may be rendered electrically conductive by dispersing therein finely divided particles of a conductive material such as graphite.

[Classes 83 (ii) and 83 (iv)] A hollow blank 1 of the form shown in Fig. 2, is shaped in dies with the aid of a mandrel having a rounded end thereby producing a somewhat lengthened blank having a globular end and a bead 7, Fig. 3, at the junction of a cylindrical part B with a hemispherical end part A. A thickened part 6 may be formed for subsequent shaping to provide a slot for a screwdriver or the like. In Fig. 4 is shown the result of partly forging down the stem part, which is completed subsequently to the form shown in Fig. 5. The result of flattening down the head part of the blank is shown in Fig. 6. A small amount of a harder metal may be welded on the head portion of the blank after forming the head to globular form, and this harder metal provides a wearing surface after completing the head. In a modification, an elongated blank is formed into two valves placed head to head in the forming dies and with a connecting web.

Title: Improvements in and relating to the etching of metals
IPC: C25F3/02
Filed: 1935-12-31
Abstract: 453,042. Electrolytic etching. MALLORY PATENTS HOLDING CO., Ltd., 19, Fenchurch Street, London. Dec. 31, 1935, No. 36050. Convention date, Dec. 31, 1934. [Class 41] [See also Group XVI] A method of etching metal sheets, particularly for use as electrodes in electrolytic cells, condensers, or rectifiers, consists in treating the sheet in an etching bath while in contact with a metallic member, e.g. a screen, which touches it at a number of points distributed over its surface, the metal of the screen &c. member being lower in the electro-chemical series of metals than the metal of the plate so that the etching is assisted by galvanic action. The sheet 9, in the form of a long strip, is first cleaned in caustic soda and then rinsed in water. While still wet it is passed into the etching bath 11 between a fine metal screen 13 on a drum 12 and a second screen 18 passing round rollers 14, 15, 16. It then passes through a washing bath 19 to a winding drum. The faces of the screens not contacting with the strip 9 may be covered with cotton gauze, canvas, sponge rubber or porous semi-hard rubber. For etching aluminium a bath of hydrochloric acid, sulphuric acid, hydrofluoric acid or sodium hydroxide and screens of silver or copper may be used.

Title: Frequency multiplier
IPC: H03B19/18
Filed: 1964-09-03
Abstract: 1,060,452. Frequency changing. MOTOROLA Inc. Sept. 3, 1964 [Sept. 16, 1963], No. 36145/64. Heading H2F. In a frequency multiplier using a varactor diode 23 to generate harmonics from a fundamental frequency source 16, a capacitor 21 provides an untuned low impedance path for harmonics above the fundamental frequency so that idler currents may circulate without dissipating energy in the source 16 or an output load 26. The capacitor may be variable to adjust the magnitude and phase of the harmonic currents for maximum efficiency of the frequency multiplier. A filter 17, 18, 20 attenuates all harmonics except the fundamental frequency, thereby preventing interaction of the generated harmonics with the source, and also provides matching between the source 16 and the frequency multiplier. A tuner unit 24 attenuates all harmonics except the required output harmonic and provides matching between the frequency multiplier and the output load 26.

Title: Improvements in and relating to methods of manufacturing tubular sheathed electric heating elements
Inventor: MOULE GORDON HENRY
IPC: H05B3/48
Filed: 1954-12-20
Abstract: 821,602. Electric heating elements. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Dec. 13, 1955 [Dec. 20, 1954], No. 36796/54. Class 39(3) A method of manufacturing a tubular sheathed electric heating element of small diameter comprises the steps of inserting a heater coil within a tube formed from a flat strilp of metallic magnesium within a tube formed from a flat strip of metallic magnesium wound into a closely coiled helix, inserting the tube containing the heater coil into a tubular metal sheath, converting the metallic magnesium into magnesium oxide in situ and sealing both ends of the sheath to exclude moisture from the heater coil. The heating element shown constitutes part of a glow plug suitable for starting a diesel engine. In manufacturing the plug, a tube 6 formed of a helically coiled strip of metallic magnesium is placed over the heater wire 1 and the sheath 7 then placed over the tube 6 after which the element is subjected to heat treatment to convert the metallic magnesium to magnesium oxide in which the heater wire is firmly embedded. The upper end of the sheath 7 is pressed inwardly around a tail 2 of the heater wire to seal the sheath and an electrically conductive connection is made by brazing or welding. The tail 3 of the heater wire extends through a tube 4 and is connected to a screwed terminal which also seals the other end of the sheath. After assembly of the element the sheath 7 may be drawn through a die to more tightly compact the magnesium oxide about the heater wire and to reduce the size of the heating element. Alternatively, the heater wire may be more rigidly secured within the sheath by packing with loose sand or loose magnesium oxide. The plug is completed by closely fitting the sheath of the heating element inside an axially bored cylindrical plug body which may have an overall diameter of 0.383 inches, the diameter of the heating element being 0.117 inches. Specification 821,601 is referred to.
