Title: Improvements relating to producing designs on support members
IPC: G03F7/04
Filed: 1946-05-04
Abstract: 625,425. Ornamenting. SOBY, W. May 4, 1946, No. 13559. [Class 93] [Also in Groups XVIII and XX] A process for producing designs on a support, e.g. name and number plates, scales and dials as for radio or television receivers, includes the steps of applying desired markings to said support, coating the support with pigmented lighthardenable material, exposing said material to light through a transparent screen having opaque areas surrounding said markings, and washing out the unexposed parts of said material to provide the markings with surrounding areas which are not coated with said pigmented material. Typically a clear glass blank is cleaned with stannous chloride and precipitated chalk, coated with a bichromated albumen preparation, and exposed through a negative bearing the desired markings, e.g. station names. The plate is next coated with a thin layer of resin and castor oil in naphtha by spraying the plate, developed in water, and powdered colours are brushed into the markings, excess being removed with cotton wool under water, and the plate is dried by spinning. The plate is then coated with a pigmented albumen - or casein - bichromated material by spraying, a translucent effect being obtainable by spraying semi-set material. This material is then contact-printed through a transparent screen having opaque areas in register with the markings previously printed on the plate, and the plate developed by washing to leave the markings surrounded by transparent areas on a dark or translucent ground. Instead of glass the support may be of celluloid, artificial resin, or metal. The Provisional Specification refers to employing a colourless light-hardenable material sprayed with a coloured laquer to give a translucent effect as an alternative to the pigmented material.

Patent GB-1507855-A (GB)
Title: Hollow-space cell and method for its manufacture
IPC: G02F1/1339
Filed: 1975-04-03
Abstract: The cavity cell is of the type comprising at least one pair of flat supports (10, 11) which are joined together along their edges, between which there is formed a cavity to accommodate a liquid crystal, and a plurality of spacers (13) having a thickness equal to that of the cavity and distributed between the adjacent surfaces of the two supports (10, 11). Within the supports (10, 11) there are created internal tensions which maintain the adjacent surfaces pressed one against the other via the spacers (13). This has the objective of rigorously controlling the thickness of the cavity, of diminishing the effect of the undulations and/or surface roughnesses of the supports, of proceeding in such a manner that the cell offers resistance to mechanical and/or thermal stresses tending to cause a variation in the thickness of the cavity of the cell. <IMAGE>

Title: Improvements relating to the electrolytic deposition of gold
IPC: C25D1/04
Filed: 1929-05-03
Abstract: 333,246. Grupe, W. F. May 3, 1929. Metal foil.-Gold leaf is made by electrodeposition on a metal strip of indefinite length; a carrier strip of non-metallic material is then applied to the gold surface by an adhesive releasable by impression transfer, and the cathode metal dissolved off. In the apparatus shown in Fig. 1 a band 12 of silver of thickness 0.001 inch connected as cathode at 18 is drawn from a drum 13 round a drum 14 of wood or hard rubber partially immersed in a gold-plating bath. A platinum anode 11 is supported beneath the drum 14 by an arm 26 which is oscillated by the rotation of the drum through a cam 27. Deposition on the edges of the silver strip is prevented by endless rubber bands passing over rollers 21, 22, 19<c>. 'The electrolyte is circulated to and from the tank 1. The plated strip 12<a> then passes through an alkali bath 15 and a water bath 16 and is dried by an electric heater 12<b>. It is then passed between pressure rollers 37, 38 together with a strip 36 of paper, glassine paper or cellophane, and the composite strip wound on a drum 40. The strip 36 is previously passed over a roller 33 fed from a heated bath 35 with heat-releasable material such as beeswax, rosin, or the substances sold under the registered Trade Marks "Cumar," " Bakelite," and " Duralite " and is cooled before joining the metal strip. The composite strip is then passed through a nitric acid bath shown in section in Fig. 4 to remove the silver. The strip 41 is passed between rollers 47 substantially at the liquid level. As shown, the paper carrier 41d is of greater width than the silver layer 41<a> and the extending edges are maintained above the bath by rods 48, 49, the lower face of the edges being protected by beeswax, rosin, or the like. The paper strip with the gold layer adhering is then passed through an alkali bath to remove acid, and though washing baths and dried. The gold surface may then be coated with shellac or or other sizing by a roller or by spraying and the strip again dried and wound. When the silver strip is of the same width as the paper the edges of both may be raised above the dissolving bath and subsequently removed by a slitting machine. Tn a modification the paper before application to the gold-plated strip is coated with an adhesive such as shellac at the edges only and these edges are cut off after removal of the silver leaving the gold leaf in the finished roll freely mounted between the paper convolutions.

IPC: C03B27/00
Filed: 1960-04-20
Abstract: 927,848. Tempering glass. TRIPLEX SAFETY GLASS CO. Ltd., J. R. BEATTIE, and K. J. B. WOLFE. April 20, 1961 [April 20, 1960], No. 13904/60. Class 56. A method of toughening at least part of a glass article, e.g. windscreen or insulator, comprises heating the article above the " relaxation temperature " (defined) and then exposing the heated glass article to the quenching action of a gaseous chilling medium characterized, by measuring energy radiated from the heated glass part being toughened and employing this measurement to control the delivery of the gaseous chilling medium used in the toughening process. The regulation of the gaseous chilling medium may be effected by a pyrometer which measures the temperature of the surface of the glass article. Alternatively two pyrometers may be used responsive to radiation emitted from the surface of the article and from the main body thereof. The pyrometer is rendered sensitive to radiation in the wavelength range 5-9Á by means of an optical lead selenide filter. A glass sheet 1 (Fig. 1) is positioned between quenching frames 2 approximately 3 inches from the surface of the sheet. A motor 3 (Fig. 2) drives pump 4 which pumps gaseous chilling medium, e.g. air, into tank 5 from which it flows through control valve 6 and via manifold 7 to frame 2. Mounted on sheet 1 is the optical pyrometer 8. The output of the pyrometer which depends on the temperature of glass surface layer is fed to control valve 6 which regulates the flow of air to the quenching frames. The valve 6 consists of a controller which is set to operate at a predetermined output voltage of the pyrometer. When two pyrometers are used they may be mounted together on or behind quenching frame 2, one measuring the surface temperature and the other measuring radiation from the whole body. They are connected to the controller through a change-over switch which enables one or both to operate. The two pyrometers may be used in opposition when it is desired to measure the temperature differential between the surface and the centre of the glass sheet. When only part of the glass article is to be toughened the other parts of the article are masked during the quenching process.
