Title: Improvements in or relating to the production of moistureproof non-fibrous cellulosic sheets or films
IPC: C08J7/052
Filed: 1946-09-25
Abstract: 626,875. Coated films. BRITISH CELLOPHANE, Ltd., BERRY, W., and OSWIN, C. R. Sept. 25, 1946, No. 28713. [Class 140] A non-fibrous cellulosic sheet or film is moisture - proofed by applying thereto a melamine-formaldehyde resin in the partially condensed or polymerized, hydrophobic state, dispersed in a liquid medium containing non- basic, water-soluble dihydric or trihydric alcohol and lactic acid in a proportion of at least 0.2 part of the acid per part of resin, reacting the resin to the final insoluble state, and coating the resin - containing sheet or film with a moisture-proofing surface coating. The resin may be applied to the sheet or film while the latter is in the gel state. The resin is applied by passing the sheet or film through an aqueous impregnating bath containing the above materials which may contain a softening agent for the cellulosic sheet or film. The non-basic water-soluble alcohol may be ethylene glycol or glycerol. The moisture-proof surface coating comprises a cellulosic base such as a cellulose ether or ester, a gum or a resin, a wax and preferably a plasticizer. By the expression partially condensed or polymerized, hydrophobic state is meant resins which are insoluble in water in concentrations below thirty-five per cent, but are soluble in water in concentrations between 35 and 70 per cent. Specifications 584,217, 593,947, and 626,876, [Group IV (a)], are referred to.

Abstract: 804,824. Medicament containers. NADAL, H. S. Sept. 21, 1956 [Sept. 22, 1955; Sept. 11, 1956], No. 28879/56. Class 81 (2). [Also in Group XVII] A container having two compartments for separately storing substances, for example a serum and a powder, is constructed such that the pressure in one compartment can be increased by a deformable cover to displace a closure member between the two compartments and permit mixing of the contents. In Fig. 2 the upper container 16 is of resilient material and has a stopper 17 in its lower face. By squeezing the container 16 the pressure therein increases and the stopper 17 is ejected. By repeated squeezing of the container 16 a pumping cycle can be effected to transfer liquid from the container 16 into the lower container 10. A spout 20 may be included which, when cut, will enable the mixture to be dispensed in drops. In Fig. 7 a one-piece container 43 has a narrowed intermediate zone 44 in which fits a disc 46 containing the stopper 17. The container is closed by a flat or protruding portion 42 of elastic material that can be deformed to increase the pressure in the upper part of the container 43 to cause the stopper 17 to be ejected. In an alternative embodiment the container shown in Fig. 7 is in two portions secured together with a disc 46 therebetween. Fig. 9 shows a construction with an upper flexible diaphragm 22 and an inner container 16 with its stopper 17 remote from its base portion 52. In all cases, the stopper 17 may be spherical instead of the truncated form shown.

Abstract: 747,644. Colour television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 24, 1954 [Oct. 22, 1953], No. 29258/53. Class 40 (3). In a colour television system in which the image for transmission is projected on to the photo-cathode of the camera tube through a colour filter grid disposed transverse the linescanning direction, the bars of the grid are so arranged in a predetermined cyclic colour sequence that the signal produced during scanning contains a number of carrier frequencies each of which is attributable to one particular colour. Thus, in one arrangement, Fig. 1, the grid is arranged with each colour cycle X made up of one black bar, one blue bar, two red bars and four green bars, whereby carriers of frequencies F, 2F and 4F appear modulated respectively with the blue, red and green colour content of the image. The black bars merely serve to maintain a regular sequence. In a transmitter, Fig. 2 (not shown), utilizing such a grid, the blue and red components are separated from the output by passing the camera signal to channels having band-pass filters tuned to frequencies F and 2F respectively and each feeding a demodulator stage. The derived blue and red components are then also reversed in phase and combined with the original signal to derive the green component. The lowest carrier frequency F is selected to be at least as high as the highest video frequency it is desired to produce by the system. A grid for use in a two-colour system is described, Fig. 3 (not shown), such a grid being suitable for use in a camera employing two tubes, one arranged to produce a high definition signal in one colour, and the other arranged with the grid to produce low definition signals in two other colours. A grid for use in a four-colour system is also described, Fig. 4 (not shown). With each of the above grids the carrier frequencies are in the ratio 2 to 1. Figs. 5-7 (not shown), illustrate further grids for three-colour systems in which the blue and red carrier frequencies are in the ratio 2 to 3. One of the grids employs no black bars. The grids may be constructed for use external to the camera tube or may be formed within the tube on the photo-cathode.
