Title: Improvements in coated compositions for planographic printing plates
IPC: B41N3/03
Filed: 1966-09-16
Abstract: 1,122,449. Planographic printing plates. OXFORD PAPER CO. 16 Sept., 1966 ]30 Sept., 1965], No. 41478/66. Heading B6C. Planographic printing plates comprising a base and a coating of a pigment and a waterinsoluble polyvalent metal xanthate of an hydroxy-containing natural polymer are made by coating the base with an aqueous composition of the pigment and a xanthate of an hydroxycontaining natural polymer, drying the coating composition and then treating it with a salt of a polyvalent metal. The various xanthates are preferably prepared by treating the natural polymer, e.g. starch or flour, with potassium hydroxide and carbon disulphide to form a potassium starch or flour xanthate which is then dried and dissolved in distilled water. The pigment preferably includes at least 50% by weight of clay, e.g. kaolin, china clay or Lustra Clay; other pigments may be used, especially colloidal silica. The starch or flour xanthate is added to the clay slip while stirring, and butyl alcohol is also preferably incorporated in the coating composition. Preferred polyvalent metals are zinc and iron; examples of salts used include zinc acetate, ferric chloride, copper sulphate and lead acetate.

Abstract: 1397166 Electric shutter SEIKO KOKI KK 11 Sept 1973 [11 Sept 1972] 42650/73 Heading G2A In shutter-release means comprising an armature urged into contact with an electromagnet by a spring, a shutter-release member in an early stage of operation energizes the electromagnet and also renders the spring inoperative. Depression of a spring-biased shutter-release member 2 effects clockwise rotation of a spring-biased pawl 13 and allows clockwise rotation of a spring-biased opening lever 6 and anti-clockwise rotation of a spring- biased shutter opening and closing lever 15 (to open the shutter). Depression of member 2 also energizes an electromagnet 25 having a pivoted and spring-biased armature 28, renders armature spring 30 inoperative, initiates a delay dependent on the light condition, and allows a spring-biased closing member 23 to rotate anti-clockwise until stopped by armature arm 28A. On expiry of the delay, the electromagnet is de-energized, allowing further anti-clockwise rotation of closing member 23, which effects clockwise rotation of lever 15 (to close the shutter). Pawl 13, opening lever 6, shutter opening and closing lever 15, closing member 23, and armature 28 return to their initial positions on release of member 2.

Abstract: 1,245,311. Producing melt-spun elastomeric filaments. KANEGAFUCHI BOSEKI K.K. 4 Sept., 1969 [4 Sept., 1968], No. 43821/69. Heading B5B. Elastomeric filaments are produced by melt spinning a segmented elastomer quenching the extruded elastomer to form filaments; directly after the said quenching, stretching the filaments so formed, so that they are elongated by at least 30% of their original length and then reducing the stretching tension which has been applied to the filaments to such an extent that they do not retain more than 50% of their original elongation. The stretching of the filaments may be effected between a first draw roll and a second draw roll driven at a peripheral speed higher than that of the first draw roll and the bundle of filaments may then be allowed to relax or retract to the required degree while travelling between the second draw roll and a take-up bobbin driven at a peripheral speed below that of the second draw roll. The elongation of the filaments in the stretching zone may be 100% to 500% and they may be cooled with a current of air in the stretching zone. The degree of relaxation of the stretched filaments may be such that not more than 20% of their elongation is retained. The stretching of the filaments may be effected in two or more stages and the relaxation of the filaments may be effected in two or more stages. The elastomer which is melt spun to form the filaments may be a segmented polyurethane. The polyurethane may have been obtained by reacting a poly-epsilon-caprolactone having an average molecular weight of 2000 and having hydroxyl terminal groups with diphenyl methane diisocyanate and chain-extending the reaction product with ethylene diamine.
