Abstract: 1,238,175. Coated sheet materials. EASTMAN KODAK CO. 18 July, 1968 [20 July, 1967], No. 34260/68. Heading B2E. [Also in Divisions Cl and G2] A support for a photo-sensitive element has a coating of the reaction product of (1) a basic metal oxide and (2) a complex of an alkyl titanate and at least one solubilizing compound which is fluosilicic acid, hydrofluoric acid, fluoboric acid, hydrogen peroxide, or a mixture of hydrogen peroxide, and one or more of said acids or phosphosphoric acids. The basic metal oxide may be selected from aluminium, titanium, zinc, hafnium, molybdenum, tungsten, silicon, chromium, iron and cadmium oxides, or fibrous boehmite. The reaction product is hydrophilic and has the properties desired as a surface, e.g. for use in the preparation of lithographic printing plates or in the preparation of colour proofing elements. The support may be wood, paper, metal, glass, polymer, e.g. grained aluminium, cellulose esters, linear polyesters such as polyethylene terephthalate, polyamides such as nylon, polyacrylic esters such as polymethyl methacrylate. In the preparation of colour proofing elements, a light-sensitive diazo resin, e.g. a formaldehyde-p-diazodiphenylamine condensate is coated upon the hydrophilic layer on a thin transparent film base. An insoluble diazo resin image is formed on the layer by exposure to a colour separation negative of the colour printing process under consideration. A two-phase lacquer containing the identical printing ink of the printing system, e.g. the red ink is then used to colour the resin image to obtain the red proof. Blue, yellow and black proofs are made similarly and the proofs then superposed in register and viewed by reflected light to predict more accurately the colour quality of the press proof to be obtained on the printing press using the same negatives for making the printing plates. Various light-sensitive layers can be coated upon the hydrophilic surfaces, e.g. photographic silver halide emulsions, light-sensitive organic compounds, examples of which are given. The two-phase lacquer composition contains a water-soluble thickener and polymer, e.g. phenol-formaldehyde resin, terpene polymers, indene and coumarone-indene polymers, rosin esters.

Abstract: 1311313 Colour television tubes RCA CORPORATION 2 Nov 1970 [31 Get 1969 (2) 3 Nov 1969] 52074/70 Heading H1D When a shadow mask is to be used for the manufacture of a colour television screen by a photo-resist process, the apertures in it are made smaller by coating it and then forming smaller apertures in the coating in alignment with the mask apertures. In one process the coating is of plastic type material in a solvent or a thermoplastic material in a liquid state which is coated on both sides of the mask. After drying, the portion covering the centre of each aperture in the mask is thinner than the side portions and may be removed by exposure to a flash from a Xenon lamp. Suitable materials are cellulose, vinyl, alkyd, phenolic and acrylic compositions; polyvinyl alcohol; gelatin; and fish glue; and they may be rendered opaque to the ultraviolet light used for screen processing by adding a water-soluble dye or carbon. Alternatively the thin centre portions may be removed by a solvent; if the coating material is an alcohol or toluene solution of an acrylic or a polyvinyl alcohol, toluene and alcohol are respectively suitable as solvents. After the screen processing the remainder of the coating may be removed by a solvent or by heat, e.g. by heating the mask during the baking out of the resist material from the phosphor screen. In another process one side of the mask is coated with photo-resist material and the other side with an ultra-violet light absorbing composition such as polyvinyl alcohol having a carbon pigment. After drying the first coating is exposed to ultra-violet light through the second coating which acts as a filter to allow more light to pass through the central regions of each aperture, and after exposure the central portions of the two coatings are removed by suitable solvents. In a modification the second coating may be omitted. A further process uses film-forming materials which shrink upon drying, such as acryloid emulsions to which may be added plasticizers such as glycol ethers and means such as sodium hydroxide to adjust the pH value to above 7. After drying, the coating shrinks to form apertures or thin pellucid areas within each aperture of the shadow mask. Another process uses a material whose viscosity is lowered by heat, such as acrylic compositions; polyvinyl alcohol containing a dye or an aromatic hydroxy compound; gallic acid; resorcinol; catechol; or 2,4-dihydroxybenzoic acid. After coating, the central regions within each mask aperture are removed by heating, preferably in a moist atmosphere, to reduce the viscosity, and the outer regions are solidified either during the same heating process or in a subsequent one. As described, the screen is of the multi-dot type and may include opaque areas between the phosphor dots.

Abstract: 1312516 Fibre optic scanning arrangement RANK ORGANISATION Ltd 26 May 1971 [8 July 1970] 33116/70 Heading G1A [Also in Divisions G2 and H4]  A fibre optic scanning arrangement comprising a line to circle converter associated with a rotating cranked fibre structure 16 is rendered insensitive to breaks in individual fibres in the converter by virtue of the provision of a double fibre arrange - ment 16a, 16b. The ends 18a, 18b arranged sideby-side are equal in size to the output ends of two fibres in the converter. The other ends of 16a, 16b lead to photo-cells 24a, 24b which are connected in parallel, each with a respective diode in series, across a resistor. Alternatively the fibres may feed a common photo-cell. The arrangement thus avoids erronious drops in output due to individual broken fibres, although the resolution is only half that of a single scanning fibre arrangement. More then two side-by-side scanning fibres may be provided. The arrangement is of use in document readers and can reproduce tones besides simple black/white markings.

Abstract: 1315246 Mammary prosthesis MALPRO CO Ltd 12 April 1972 [1 June 1971] 18275/71 Heading A5R A mammary prosthesis 1 comprises a hollow flexible casing, the hollow space therein being partially filled with a mass of granules (7), Fig. 3 (not shown), the casing having a base portion (not shown) adapted to lie against a wearer's body, and being formed of a resilient material comprising two layers (4), (5), Figure 2 (not shown), of textile fabric enclosing a space filled with fibres (6). A cup-like portion 2 of the prosthesis is provided with darts or folds 3 sewn into the material, the base portion being sewn onto portion 2 to form a hollow casing. The hollow space within the prosthesis is approximately two thirds filled with granules of a specific gravity 0.9 to 1.5, which are inert to water, and can be made of polystyrene. The granules are ellipsoidal in shape, Figures 3a, b (not shown), and as a result the granules settle in the hollow space with their elliptical crosssections lying in a horizontal plane. This has the effect of lowering the centre of gravity of the mass of granules compared with that of a mass of spherical granules and restricts vertical movement of the granules to a certain extent.

Abstract: 1319973 Stamping DAVY & UNITED ENG CO Ltd 28 May 1971 [13 June 1970] 28750/70 Heading B3Q A pendulum marker for marking moving articles has an adjustable mounting for the pendulum arm, one position of the mounting supporting the pendulum in the path of the articles to be marked and another position of the mounting limiting the pendulum to swinging above the path. In one form, Fig. 2, a cranked arm 13 is used which swings on a pivot 15 carried by a beam 16 on a pivot 17. A pin 21 on the arm is engaged by a lever 22 having a latch portion 27 for retaining the pin, Fig. 2 (not shown), when the arm is raised by impact with a billet 31. The arm 13 now returns to the vertical by rotation about the pin 21, as permitted by rotation of the beam 16 about its pivot 17. To release the arm for vertical movement into the path of the next billet, the lever 22 is turned about its pivot 23 by an actuator 25 operated by the tail of the marked billet. Alternatively, the pendulum may drop vertically on to the billet and be held by a stop with the arm vertical. When the pendulum falls clear of the moving billet the stop is disengaged, the leading end of the next billet to be marked may control operation of the cylinder 25, through a photo-electric cell on billet guides which are adjustable for billet size and so that the photo-cell moves further from the marking position as the guides are moved closer together, for smaller, faster billets. In a modification, Fig. 3 (not shown), the pendulum arm (13) is mounted direct on a solenoid or fluid-pressure actuator (41) which raises the pendulum (12) when this operates a switch (44) after impact. The actuator may be double-acting to assist in lowering the pendulum.
