Title: Improvements in or relating to Photosensitive Slurries and Their Preparation.
Inventor: KOBAYASHI YOSHICHIKA
IPC: H01J9/227
Filed: 1967-10-23
Abstract: 1,197,772. Luminescent materials. MATSUSHITA ELECTRONICS CORP. 23 Oct., 1967 [1 Nov., 1966; 11 April, 1967], No. 48010/67. Heading C4S. [Also in Division G2] A photo-sensitive slurry comprises polyvinyl alcohol, 1 to 30% by wt. of ammonium dicliromate phosphor particles and a quantity of Ge dioxide, tetra-chloride, disulphide or an orthogermanate ester, which gives 0À001 to 1À25 gm. of GeO 2  per 100 c.c. of P.V.A. solution. The Ge compound maintains photosensitivity by preventing an increase of the pH value and also prevents a reduction in phosphor emission due to adsorption of chromium on to the phosphor. Components of the slurry are blended together or the dichromate may be added during blending. The GeO 2  may be added as metagermanic acid, ethoxy germanium or ethanol containing GeCl 4 . Phosphors referred to are Eu actuated Y, Gd and Y-Gd oxides, Y and Gd oxysulphides and YVO 4  also ZnS and ZnCdS. A dot pattern on a colour T.V. tube is formed by applying the slurry and exposing to U.V. light through a shadow mask.

Abstract: 1,235,288. Advancing mine roof supports. GULLICK DOBSON Ltd. 11 Oct., 1968 [1 Nov., 1967], No. 49556/67. Heading E1P. Misalignment and the tendency of an advancing mine roof support to move downhill in an inclined seam is prevented by a jack 15 acting in association with a strut 28 adapted to bear on a rail R fixed to a conveyor C. The jack 15 is slidably mounted on the rail by a clevis 10 and is pivoted to a locking lever 12 in turn pivoted to a like sliding clevis 11 having an abutment 18. The above arrangement is such that when the jack 15 is extended its piston rod 14 is held stationary by a dog or tooth 17 on the lever 12 so that the cylinder of the jack and the associated clevis 10 move up hill. When the support is advanced the strut 28 bears on the rail 12 to act as a fulcrum about which the support pivots during contraction of its ram 27.

Title: Method for surface treatment of wood
IPC: B27K3/15
Filed: 1971-11-03
Abstract: 1374289 Surface treatment of wood E G L ERIKSSON 3 Nov 1971 [3 Nov 1970] 51040/71 Heading DIP A method for treating the surface of wood, comprises pretreating the wood with a liquid hydrophilic substance substantially free of solvent and which facilitates penetration of the wood surface by an impregnation agent, the substance being caused to harden thereafter by subsequent treatment with the impregnating agent which reacts with the substance to form a polymer. The substance may be phenol or resorcinol. The agent may be an aqueous solution of hexamethylene tetramine, melamine formaldehyde or an intermediate reaction product of phenol and paraformaldehyde. Disproportionate penetration of the end surfaces relative to the other surfaces is prevented by initially applying an aqueous melamine resin to the end surfaces. This reacts with the phenol during the pretreatment to form a phenol insoluble polymer which prevents further penetration of the end surfaces. The phenol pretreatment may be effected at elevated temperature. Sulphuric acid or stannous chloride may be added to the phenol. The pre-treatment may be followed by a vacuum treatment. The subsequent impregnation may be at elevated temperature and pressure. This may be followed by a heat treatment which may be in two stages (a) oven at 80-140‹C for 1-2 hours and (b) hot press at 130-180‹C for 5-20 min. The surface finish is durable, abrasion-resistant and may be water repellant.

Abstract: 1330669 Feeding and delivering sheets WESTINGHOUSE LEARNING CORP 28 Oct 1970 [21 Nov 1969] 51140/70 Heading B8R [Also in Division G4]  Feeding documents.-A voice coil solenoid 38 pivots a continuously rotating feed wheel 32 about shaft 25 so that it engages the bottom of the stack through an aperture in plate 20. Side rail 14 is provided with a knife edge at its lower end and the gap 40 between rail 14 and plate 20 is sufficient only to allow one document to be fed at a time. Document transport.-The documents follow a figure of 8 path past read head 52 so that both sides may be sensed, the path being defined by guide plates 44, 54, 66, 54, and 80, and drive being provided by rollers 48, 62, 68, 72, 78, 82. Idler roller 84 may be disengaged from roller 82 so that the document is halted in path 81 while a decision is made whether to recirculate the document round the figure of 8 path or to discharge it by operating a gate 42. Delivering documents.-After travelling between guide plates 91, 93, a discharged document is inverted by guide plate 94 and drive roller 96 before insertion in the bottom of output hopper 100, so that the output stack is in the same order as the input stack 10. Modified embodiment.-Fig. 5 (not shown). The document transport is arranged to invert each document and return it past the read head without the paths crossing, and there is no facility for recirculating the documents. Should documents be fed in overlapping relationship in this embodiment, no jamming will occur because the forward and return paths do not cross, and if documents are fed too closely spaced, in most cases they will slide over one another in opposite directions.

Abstract: 1447743 Powder coating composition FORD MOTOR CO Ltd 5 Dec 1974 [5 Dec 1973] 52684/74 Headings C3B and C3P Powder paint compositions are prepared by the following process. (A) A solution in an inert solvent of a copolymer (M.W. 1000-15,000, glass trans. temperature 40-90 C.) having cross-linkable functional groups is introduced to an evaporating zone. (B) The solutuon is heated at a temperature > the melting point of the copolymer but < the degradation or gelling temperature. thereof and higher than the temperature at which the solvent begins to vaporize. (C) The solution is passed from the evaporating zone, while maintaining the temperature > the melting point of the copolymer, to a separating zone. In this zone the solvent vapour is removed to leave non-volatile components which latter are mechanically driven from the separating zone. The non-volatile material is cooled to a solid and then pulverized to form the powder paint composition. The first steps may take place in a plate evaporator, e.g. as disclosed in U.S. Sepecification 3,073,380. A drawing (not shown) illustrates a conical separator, having a tapered screw at the bottom thereof, suitable for the separation zone. Both the evaporating and separation zone may be maintained at 250-600 F. A reduced pressure may be maintained in the evaporating and separating zone, e.g. 10-500 mm.Hg. A pressure of 40-70 p.s.i. may be used to drive the non - volatiles from the separating zone. Examples relate to glycidyl acrylate copolymers cross-linked, e.g. with azelaic acid; acrylic acid, methacrylic acid copolymers cross-linked with epoxy resin (a diglycidyl ether of bisphenol A); a 2 - hydroxyethyl methacrylate / methacrylic acid / methyl methacrylate / butyl acrylate copolymer; and a 2-hydroxyethyl acrylate/ethyl acrylate/methyl methacrylate copolymer.
