Filed: 1952-02-05
Abstract: 708,092. Lubricating. RANKIN, H. Feb. 5, 1953 [Feb. 5, 1952], No. 2992/52. Class 12(3) In a lubricating device for flexible shaft and like transmissions, the lubricant is supplied from an outside source to a hollow body, one end of which is completed by a detachable member through which passes one end of a flexible shaft, means being located within the hollow body for holding the flexible shaft end, the arrangement being such that when the member is secured home on the body it imparts a compressive force to the holding means so as to make a lubricant-tight joint. As shown, a hollow body 1 has a nipple 2 for receiving a grease gun fitted to one end, the other end having a gland nut 3 with an opening through which passes one end of the flexible shaft transmission or like mechanism. The flexible shaft end is secured in place by a gland member 5 located between washers 6. The member 5 is radially slitted to facilitate entry of the flexible cable.

Filed: 1952-02-07
Abstract: 707,267. Making metal fabrics; welding. ROESLER, W., and ROESLER, J., [trading as DRAHTWERK, J. ROESLER KOMMANDITGES.] Feb. 7, 1952 [Feb. 7, 1951], No. 3272/52. Class 83 (4) In a method of making wire netting, each cross wire is laid above or below longitudinal wires by a shuttle reciprocable along a straight or curved path, and is subsequently welded to the longitudinal wires. The shuttle 5, reciprocable on a raceway 6, introduces the cross wire 3 above or below the longitudinal wires 2. Alternately operated fingers 99 move up to the wire 3 and press it against loop holders 16 to correctly locate the cross wire between the electrodes 10, 11, the electrode 10 being resiliently mounted on a bridge 19 vertically movable by an eccentric to press the electrodes together for welding. After welding the holders 16 are lifted and the netting advanced for the next cross wire to be laid. In modifications the cross wires are laid directly between the electrodes by a shuttle moving on a straight path, Fig. 5 (not shown), or a curved path, Fig. 6 (not shown).

Title: Improvements in or relating to selection arrangements for selecting a control oscillation in a frequency range
IPC: H03L7/12
Filed: 1966-01-25
Abstract: 1,073,675. Automatic frequency control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 25, 1966 [Jan. 28, 1965], No. 3294/66. Heading,.H3A. An automatic frequency control system adapted to select a control oscillation in a particular frequency range in the presence of parasitic interference oscillations, comprises a local oscillator (24) an output of which is mixed with the control oscillation (supplied to terminals 1) in an amplitude-sensitive phase discriminator the output of which is fed through a low-pass filter (18-20) to a frequency-correcting arrangement (30) connected to the oscillator, the natural frequency of the oscillator being outside the frequency range and a sweep oscillator being provided to sweep the oscillator through the range until it locks on. Since the natural frequency of the oscillator is outside the range, a large output from the discriminator is necessary to lock the oscillator; the required control oscillation is capable of producing this output, but a parasitic oscillation (e.g. a sideband frequency) will not have sufficient amplitude. The sweep oscillator comprises a multi. vibrator (45, 46) the output of which is differentiated (capacitor 49) and causes a capacitor (19) in the low-pass filter to charge to the negative supply potential; the discharge of this capacitor sweeps the oscillator (24) through the range. When the phase discriminator produces an output sufficient to hold the oscillator at the control frequency, the multivibrator is disabled by an amplitude discriminator circuit (33-42) fed from the phase discriminator.

Title: Method of producing an intermediate metallic oxide film in a multiple layer article
Inventor: WEINRICH ARTHUR ROBERT
IPC: C03C17/36
Filed: 1953-02-07
Abstract: A multiple layer article having an intermediate film of a metal oxide is formed by depositing on a support, by thermal evaporation or sputtering, a film of Mg, Sn, Pb, Fe or Ti, depositing directly upon such film a coating of a material difficult to oxidize and of such thickness as to be pervious to the passage of oxygen at high temperature and heating the article in an oxidizing atmosphere at high temperature so as substantially completely to oxidize the intermediate film throughout its depth without oxidizing the outer coating.  The support may be of glass, porcelain, tile, ceramic, earthenware, aluminium silicate, calcium silicate, mica, silica or metal and the outer coating may be of Pt, Pd, Rh, Ir, Ag, Au, MgF2, CaF2, cryolite, silica, zircon, ZrO2 or ZnO.  Additional layers may be formed e.g. an inner and outer oxidisable film with an intermediate non-oxidizable one such as Pb-Au-Pb; or first and third oxidizable layers with a second layer of Au and an outer layer of SiO2; alternatively two adjacent oxidizable films may be oxidized through a non-oxidizable one.  In a modification, to give a decorative effect, part of the surface is masked during the oxidation step.

Abstract: 1473852 Decorative laminated surfacings FORMICA INTERNATIONAL Ltd 27 Jan 1975 [25 Jan 1974] 03590/74 Addition to 1399624 Heading B5N A decorative surfacing structure is made by etching portions of a continuous metal coating on a surface of a transparent heat-set biaxially oriented polyethylene terephthalate film to leave a metallic pattern, design or legend, and bonding said etched surface to a flexible fibrous backing sheet via an intermediate adhesive layer. The metal may be Cu, Ag, Au, Ni, Cr or, preferably, Al, which may be vacuum-deposited, and may be reflective, opaque or translucent. The film may be coloured and embossed or printed, and the adhesive and backing may be coloured, patterned or printed for desired visual effects. The adhesive may be thermoplastic or thermosettable, hot-melt polyester being preferred; it may comprise a coating on the backing and/or film, an impregnant on the backing, or a pre-formed sheet or foil. The backing may be woven textile or glass, non- woven cellulosic, synthetic or glass fibres, or, preferably, paper. The discontinuous metal coating may be obtained by printing a continuous coating with etch-resistant ink and etching the remainder; the ink may then be removed or may remain and give a decorative effect through "undercutting". The backing and film may be united by heat and pressure, e.g. between rollers, and the backing may subsequently or simultaneously be applied to a substrate, e.g. walls, doors, furniture or panels of chipboard, blockboard, hardboard, plywood, asbestos cament board or plasterboard, by means of pressure-, solvent-, heat- or wateractivated adhesive coatings on the backing. The exposed surface of the backing may also bear anti-curl coatings and/or discrete polymeric areas for facilitating removal of the surfacing from a substrate. The surfacing may be bonded to polymeric materials by adhesive, hot-melt coating or extrusion, or backed with hot-melt polyethylene for packaging.

Abstract: 1,272,743. Detonating explosive charges. DYNAMIT NOBEL A.G. 28 Jan., 1965 [3 Feb., 1964], No. 3722/65. Heading F3A. In a process for generating a predetermined and defined detonation front in an explosive by means of an electric conductor, the latter is formed with alternate portions of large and small cross-section and, for initiating the detonation, is charged with an electric current of such a strength as to only cause vaporization of the regions of small cross-section. By way of example, when a manganin wire of 0À15 mm. diameter arranged coaxially of a cylindrical explosive column of 40 mm. diameter and a length of 400 mm. is loaded with a current impulse of 550 watt-seconds and a potential of 10 kilovolts, the detonation reaches the surface of the explosive cylinder at various points with time differences of up to 30 seconds, but when a wire consisting of alternately succeeding manganin wire sections of 0À15 mm. diameter and a length of 20 mm. and copper wire sections of 1À4 mm. diameter and a length of 2À5 mm. is used, the same high voltage discharge results in time differences of only 0À5 to 2À0 seconds. In a further example, detonating caps are embedded in the explosive, being open towards a wire placed adjacent to and spaced from the open ends of the caps. The wire is formed with alternate portions of small cross-section and large cross-section.
