IPC: B41N1/14
Filed: 1970-05-28
Abstract: 1,252,866. Printing plates. COLUMBIA RIBBON & CARBON MFG. CO. Inc. 28 May, 1970, No. 25779/70. Heading B6C. A planographic printing plate is made up of a base of a solvent-etched synthetic thermoplastic resin, such as polystyrene, and a surface layer which constitutes the printing surface. A hydrophilic layer may be interposed between the base and the surface layer. The base may be in the form of a strip, perforated at its edges so that the strip may be fed through a printing machine or printing plates cut from the strip may be secured to a printing cylinder. In an example a web of etched polystyrene is coated with a hydrophilic composition by weight: Alternatively the latter composition may be applied directly to the etched polystyrene. In either case the coated base is then dried. Printing plates according to the invention may be imaged by printing, and may carry a transfer coating on their rear faces so that a copy sheet, bearing the same image as the printing plate, may be produced at the same time.

Abstract: 1,257,015. Plasma discharge apparatus. G. V. PLANER Ltd. 31 Jan., 1969 [3 Nov., 1967; 14 Feb., 1968], Nos. 50051/67 and 7163/68. Heading H5H. [Also in Division C7] A vacuum evaporation coating process in which a conductive, semi-conductive or insulating evaporant enclosed by an electrode having at least one hole for directing the evaporant towards the substrate is initially heated at a pressure not lower than 10<SP>-3</SP> torr and an electric discharge generated in the evaporant plasma is then the sole heating source for maintaining the evaporation. The evaporant may be initially heated by electron beam, resistance, R.F. or an ionizable gas may be introduced between the discharge electrodes to provide an initial plasma. This initial heating source is removed once the evaporant plasma discharge is generated. The substrate may be a metal plate or strip such as steel on a plastics film. Al or Zn may be evaporated and coated on the steel strip moving past the evaporant source. The evaporant 2 in a hearth 1 is connected to an electrode 5 and connected to a D.C. source 10 and surrounded by a spherical Ta electrode 3 with an aperture 4 opposite the substrate 9. The chamber is pumped down to a pressure not less than 10<SP>-3</SP> torr and initial heating is effected by electrons generated from a heated cathode 8. The high P.D. between electrodes 5 and 3 generates a discharge in the evaporant plasma and evaporation is continued without the electron beam. Alternative arrangements disclose an electron gun outside the chamber instead of cathode 8; an elongated trough for the evaporant supported within a cylindrical electrode; two electrodes of the evaporant with an adjustable gap between them for generating the discharge; a central anode coated with the evaporant and surrounded by an electron filament and a cylindrical cathode.

Abstract: 1,267,262. Manufacture of sulphuric acid. STICKSTOFFWERK PIESTERITZ VEB. 5 Jan., 1970, No. 456/70. Heading C1A. Sulphuric acid is manufactured by treating SO 3  containing gases with water vapour at a temperature above the dew point of sulphuric acid and condensing the sulphuric acid in a plate column down which cone. H 2 SO 4  is passed in counter-current flow to the gas mixture resulting in the formation of foam layers in which the condensation of sulphuric acid from the gas mixture takes place under conditions such that no formation of mists occurs and the condensation and absorption of H 2 SO 4  are optimized. The SO 3  containing gas is used at a temperature between 300‹ and 380‹ C., the water vapour as saturated or superheated steam at a temperature between 125‹ C. and the temperature of the SO 3  containing gas, and the temperature of the feed acid to the plate column is between 155‹ and 240‹ C. The optimum condensation and absorption conditions in the plate column are achieved by virtue of the large surface area of the foam layer which is produced therein. The feed acid concentration is between 94 and 98À3% and the temperature of the plate column is maintained by variation of the sprinkling density of the cooled circulated acid.
