Title: Polymer solutions
IPC: C08J3/09
Filed: 1956-11-28
Abstract: Interpolymers of 45 to 55 mol. per cent of vinylidene cyanide with at least one other olefinic monomer are dissolved in organic sulphoxides of the form R2SO where R is an alkyl radical or a chlorine-substituted alkyl radical having 1 to 3 carbon atoms. Specified sulphoxides are dimethyl sulphoxide, diethyl sulphoxide, methylethyl sulphoxide, dichloromethyl sulphoxide and di-b -chloroethyl sulphoxide, which may be mixed with other solvents, e.g. dimethylformamide, nitromethane and acetonitrile, and non-solvents, e.g. dioxane and acetone.  Olefinic comonomers which give 1 : 1 alternating copolymers, e.g. vinyl acetate, or mixtures of such comonomers, e.g. butadiene and styrene or vinyl acetate and acrylonitrile, and those mentioned in Specifications 681,120, 683,655, 688,339 and 726,068 may be employed. Agglomeration may be avoided by dispersing the powdered polymer in the cooled sulphoxide and then heating the dispersion till the polymer is dissolved.  The solutions may be used for spinning fibres and casting films. Examples describe casting films from (II) dimethyl sulphoxide solutions of vinylidene cyanide-vinyl acetate copolymers on polished surfaces, and (VI) dimethyl sulphoxide solutions of vinylidene cyanide-butadiene-styrene terpolymers on a hot plate at 120 DEG  C. Specifications 653,468 667,276 and 673,722, [both in Group IV (b)], also are referred to.

Abstract: 1322615 Film scanners EASTMAN KODAK CO 3 Aug 1971 [3 Aug 1970] 36407/71 Heading H4F The scanning of a flying-spot scanner 10 scanning a continuously moving film 28 is synchronized by signals derived from movement of the film. In the embodiment of Fig. 1 a disc 64 is rotated with a sprocket 32 driving the film and the disc is formed with concentric rings of indicia 66, 68, which may be transparent or opaque and are detected by a light source and photosensors 70, 72. The outer ring 66 has ten indicia which produce via photosensor 70, multivibrator 76 and integrator 80, 82 a sawtooth waveform for the field scanning of scanner 10. Deflection of the whole scanning raster to follow the continuously moving film frames is accomplished using the ring 68 of four indicia, one per sprocket projection 74, the film having a sprocket hole per frame. The indicia of ring 68 are in phase with certain of the indicia of ring 66 and alternate film frames are scanned by two and three fields of scanner 10. The disc 64 may carry four rings of indicia, one set of two rings being used with films of 24 film frames/second and the other two rings being used with films of 18 film frames/second. In a further embodiment (Fig. 5, not shown) where the scanner field rate is three times the film frame rate, the synchronizing signals are produced by shining a light through the sprocket holes in the film 28 on to a set of three photosensors, the outputs of all three photosensors being used to synchronize the field rate and the output from one photosensor being used for deflection of the scanning raster. In any embodiment the monostable multivibrators 76, 78 may be replaced by bi-stable multivibrators, with each photosensor being replaced by a pair of photosensors, the set and reset inputs of the multivibrators being fed from different ones of each photosensor pair.

Abstract: 1501672 Luminescent materials SPERRY RAND CORP 11 Sept 1975 [13 Sept 1974] 37362/75 Heading C4S [Also in Division H1] A two colour CRT luminescent screen comprises particles of a La compound containing Tb ions which are uniformly distributed and Eu ions in the outer regions of the particles with a concentration increasing towards the outer surface. The Eu ions may occur throughout the particles. The compound is La 2 O 2 S which contains Tb 2 O 2 S and Eu 2 O 2 S. The ratios of Tb and Eu to La are 0À01 to 0À04 and 0À001 to 0À1. The particles are produced by (a) ball milling a mixture of La 2 O 2 S : Tb and EuCl 3 ; (b) firing at 700-1200 C. in a flowing atmosphere of 60% A, 38% HIS and 2-3% H 2 O; and (c) cooling in a similar atmosphere. The EuCl 3  may be replaced by Eu oxide or a chelate, e.g. diketones and dionates. The turn on voltage of the particles is increased and then brightness reduced both by the ball milling and by adding the Eu in stages, repeating steps (a), (b), (c) at each stage. In a penetron CRT screen the particles are mixed with Eu activated YVO 4 , Y 2 O 3  or Y 2 O 2 S and deposited by settling. With high energy electrons green light is produced by the Tb ions. At low energies there is a quenching effect caused by a transfer of energy from Tb ions to Eu ions to give red light. CRT's are used for radar and data displays using raster scanning or random beam positioning. A filter may be used to increase contrast. Detailed examples are included.
