Title: Method for producing relief images
IPC: G03C1/705
Filed: 1972-05-16
Abstract: 1397566 Photographic processes ENERGY CONVERSION DEVICES Inc 16 May 1972 [17 May 1971] 23005/72 Heading G2C A method of producing a relief image comprises imagewise exposing a material which causes the  material to change either from (a) amorphous to crystalline or (b) planar crystalline to jagged crystalline or vice-versa and also causes a change in solubility, and removing the more soluble areas with a solvent in the presence of an electrical field. Specified materials are compositions of Ge and/or Te and Se/S as disclosed in Specifications 1070411, 1070412 and 1283542; these compositions may be admixed with promoters, e.g. metal halides, which promote the conversion to the crystalline form from the amorphous form as disclosed in Specification 1364288. Generally the amorphous material is applied to a support, imagewise exposed to a laser, flash or ultra-violet to convert the exposed areas to the crystalline form and developed in a solvent (oxidants such as sodium hypochlorite or A 2 O 2  for Ge and/or Te amorphous compositions; CS2 for crystalline Se compositions; Br in methanol for crystalline Ge and/or Te compositions) in the presence of an electrical field generally using a metal support as one electrode. Alternatively, the amorphous material may be uniformly exposed to convert it to the planar crystalline form and this may be imagewise exposed to produce jagged crystals which are more readily dissolved by oxidants or Br/methanol mixtures. The relief images may be used to produce printing plates, originals or electrical components. For originals, it is preferred to use a transparent support, a Cr layer and then a layer of the material whereas for lithography, a hydrophilic Al or polymeric support is preferred as the relief image is generally oleophilic. However the relief image can be rendered hydrophilic by treatment with aqueous solutions of AgNO 3 , SnCl 2  or nickel salts. Printed circuits can be produced if there is an electrically insulating layer on the opposite side of the metal support. The electrical component may be electro-plated either on the relief image or the bared support, whichever has the greater conductivity. Alternatively, the relief image may be produced by imagewise exposure of the material to produce a latent image followed by uniform exposure, generally heating, to produce an image which can be selectively dissolved.

Filed: 1929-07-27
Abstract: 337,055. Barcan, H. July 27, 1929. No Patent granted (Sealing fee not paid). Moulding rubber tyres.-Solid rubber ' band ' tyres are formed by moulding comminuted scrap or crumb rubber 4 on to the ' band ' 1 of a used tyre on which the original hard rubber layer 2, with or without a layer 3 of the original softer rubber, is still adherent. The moulding apparatus shown in .Fig. 4 comprises a base-plate 5, an outer ring 6, and a top-plate 7. The crumb rubber is first fed through a hopper 9, and the plate 7 fitted and forced home by a press-operated ring 10. A retaining ring 11, held in position by taper plugs 12, serves to hold the plate 7 after the pressurering 10 is released. Thrust-screws 15 may be used to correct any irregularities in the shape of the band 1.

Abstract: 888,054. Additional air admission devices. AUGUST, P. July 1, 1960 [July 2, 1959], No. 23146/60. Class 7(2). An extra air inlet between the carburetter and the cylinders of an engine comprises two pistons 1, 4, Figs. 1 and 2, piston 1 being controlled in dependence on the carburetter throttle control by means of a Bowden cable 2 whereas the other piston 4 is adapted to follow it up under the action of a spring 5 if not braked by the suction in the induction pipe acting through a port 7. A nose or groove may be provided on the pistons to guarantee a limited through-flow cross-section. The additional air enters the pipe 8 from the carburetter or other air filter and passes through the variable cross-section between the two pistons and through a tapered valve slot 9 controlled thereby to a duct 10 from where it travels via ducts 14, 15 to mixing zones 16, 17 in each induction pipe B. The additional air enters the induction pipe via conical inserts, Fig. 3, tapered in the direction of flow and is first supplied to the duct 14 from slot 9 and as the piston 1 moves to the right additional air is supplied via duct 15. Each mixing zone may be supplied with additional air through two ducts, one longer than the other.

Abstract: 1,048,036. Two part couplings. BADISCHE CONTACT-FABRIK G.m.b.H. June 11, 1963, No. 23147/63. Heading H2E. A contact socket has a hollow resilient insulating carrier in the form of a cylinder 2, Figs. 1, 2 (not shown), or a prism, containing separate contact elements 3 disposed lengthwise around the bore. The elements 3 may be circular or trapezoidal in cross-section, and if circular may be fixed or rotatable; and they may be secured by bending projections 4 from their length over the ends of the carrier and embedding the ends in the outer surface of the carrier. Alternatively the whole length of the elements may be stuck to the carrier, by adhesive or by vulcanizing or may be partially embedded in it (Figs. 3, 4, not shown). Alternatively, if larger contact elements are used, 6, Figs. 5, 6 (not shown), they may be retained in the carrier by a ring 10 which engages in a waisted portion 9 of the elements, and forces them against the carrier, or they may be close-packed to render them self-retaining.

Abstract: 669,427. Spark-gaps. STANDARD TELEPHONES & CABLES, Ltd. Sept. 7, 1949, No. 23170/49. Class 39 (i). A cold cathode gas discharge tube particularly suitable for use as a voltage limiter in connection with low voltage power supply or communication lines comprises an annular metal disc 12 sealed between a pair of collars 4 and 5 of insulating material such as glass or ceramic and a pair of endplates 10 and 11 sealed to the respective collars. As an alternative to the usual seal in which glass is fused to metal, a plastic hermetic sealing cement to which metal and glass or ceramic adhere may be used. The annular disc 12 carries a rectangular portion 13 twisted through a right-angle, as shown, to form with the end-plates 10 and 11 two coupled discharge gaps. The portion of the disc extending beyond the collars 4 and 5 forms an external cooling-fin, and the fact that the two plate electrodes 10 and 11 form part of the envelope also provides for easy heat dissipation. The assembly is filled with a suitable gas, such as hydrogen at 100 mm. pressure through a hole 8 while the device is still on the exhausting pump, the hole being then sealed with solder or other sealing material 9. In a modified construction the rectangular portion 13 is omitted and the end-plates 10 and 11 are dished inwardly towards the annular disc 12 to form annular gaps between the inner edges of the disc and the respective end-plates.

Abstract: 424,775. Kinematograph apparatus. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Aug. 24, 1933, No. 23565. Convention date, Aug. 25, 1932. [Class 97 (i)] In film magazines for apparatus having intermittent feeding means adjacent the exposure aperture, and no guiding means between the magazine and the exposure aperture, the elasticity of the film is utilized to maintain the film at rest at the exposure aperture by constructing the film openings in the magazine so that the parts of the film between the spools and the exposure aperture are so guided as to form substantially free loops within the magazine between the spools and the film openings; the openings are also arranged at such a distance from the walls of the magazine that the film does not contact with the walls during its movements, and film-controlled braking means may be provided for the takeup spool. As shown, the magazine 1 has plush-lined film openings 4, 5, inclined to the front wall of the magazine, and a lever 8, pivoted at 9, carries a roller 10 which is pressed against the film loop by a spring 11 ; the roller brakes the spool 6 when the loop shortens. Ribs 7 prevent the film from contacting with the wall 1<a> of the magazine.

Abstract: 370,804. Transmitting signals along an electric power transmission line. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fallou, J. ; 3, Rue de Messines, Paris.) Sept. 1, 1931, No. 24557. Convention date, Sept. 2, 1930. [Class 118 (ii).] For transmitting signals from one point to another of an electric power-transmission network, sustained mechanical vibrations of high frequency are impressed on one or more of the cables of the network, thereby causing ultrasonic waves to travel along the cable from the emitting to the receiving station. The signals may be transmitted along the earth wires of an overhead power-transmission network. A piezoelectric device may be used for producing the high frequency mechanical oscillations.
