Filed: 1955-05-02
Abstract: 814,124. Cathode-ray tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 30, 1956 [May 2, 1955], No. 12711/55. Class 39(1). The wall of a C.R.T. upon which an image is produced by electron bombardment is made in one or more of zones 12 of such thinness as not materially to impair the definition in contact photography and to withstand a pressure differential of at least one atmosphere. The wall 3 may be a thin glass membrane stretched over a grill, lattice or honey comb of glass or metal, the membrane being coated with a phosphor 4 and a reflecting layer e.g. Al. The photographic plate is brought into close contact with the wall by means of a film of optical oil. Alternatively a single zone of reduced thickness is formed in a glass wall, the zone being 2 mm. wide and about 0À001 inch thick, Fig. 2 (not shown). This arrangement is useful in spectroscopy. A complete picture for the whole of the area of the multzone end wall may be built up in several ways (1) by moving the tube laterally relatively to a fixed photographic plate (2) by electro magnetic deflection of the beam and corresponding shift of the plate, and (3) by providing two windows displaced from one another in a direction perpendicular to the tube axis and the long dimension of the zones, the electron image being focussed alternately on one of these windows, giving two complementary pictures which can later be combined. Similarly a mosaic of small square windows may be used.

IPC: B41M5/132
Filed: 1954-05-04
Abstract: 757,136. Printing processes. CARIBONUM, Ltd. April 19, 1955 [May 4, 1954; July 26, 1954], Nos. 12982/54 and 21780/54. Class 100 (2). [Also in Group VIII] Characters are produced on sheet material by applying pressure, e.g. by writing or typing on a superposed sheet the pressure causing an acid substance to come into contact with an alkaline substance in association with a colourless dye-stuff ether carried by the sheet material so that the alkaline substance is neutralized and the dye-stuff ether is converted into the coloured dye-stuff. By this means a number of copies may be made on superposed sheets by writing, typing or the like on the top sheet. In one arrangement the alkali dye-stuff is carried by one side of each sheet and the acid by the other side. When the sheets are then pressed together by writing on the top sheet, the acid reacts locally with the alkali dye-stuff and causes the colour to appear. There need be no coating of alkali dye-stuff on the upper face of the top sheet, nor of acid on the under face of the bottom sheet. These sheets may be arranged for sale in packs of from two to ten sheets being kept apart to prevent premature neutralization by minute globules of solid material, e.g. wax, a synthetic polymeric material, gum or dextrin. In another arrangement both coatings of alkali colourless dyestuff and of acid are applied to the same side of a sheet between separated by a barrier layer which is broken down by applied pressure to allow the dye-stuff to be neutralized and become coloured. The dye-stuff ether used may consist of one or more colourless ethers, e.g. the butyl ether, of triphenylmethane dye-stuff, e.g. Methyl violet 2B, Methyl violet 10B, Magenta, Malachite green A and mixtures of these. The alkaline substance may be an hydroxide, carbonate, bicarbonate or mono-hydrogen phosphate of sodium or potassium. Alternatively, morpholine or triethanolamine or a mixture of these may be used. The acid substance may be an acid wax, tannic acid, gallic acid, oleic acid, lauric acid, ricinoleic acid, or mixtures of these. The sheet of paper to be prepared may first be coated with a layer comprising ethyl cellulose, vinyl acetate, gelatine, chlorinated rubber, cellulose acetate or mixtures of these, to prevent absorption into the paper of the substances carried by it. Similar substances may be used for the barrier layer where the alkali dye-stuff layer and the acid layer are applied to the same face of the sheet.
