Abstract: 1,129,812. Contact printing apparatus. HARRISON & SONS Ltd. Sept. 27, 1965 [Sept. 30, 1964], No.39856/64. Heading G2A. [Also in Divisions B2, B3, B4 and C7] A method of making a perforating tool comprises removing metal from the surface of a tool blank, by a process such as etching, engraving, or spark erosion, to form projections and grinding the projections to form sharp perforation-defining edges. The tool may be a flat plate or a roll and is for use in a machine for perforating or forming an intaglio effect on sheet material such as paper in which material in contact with the projections is perforated by rubbing contact, e.g. of a cylinder of cutting knives rotating at high speed, with the other surface of the material. In the forming of pins, for perforating sheets of stamps, on a roll 4 the roll is cleaned and prepared for electrolytic etching. Photosensitive resist is distributed over the roll whilst it is rotated by means of a nozzle and brush. Alternatively the roll is coated by spraying, ring coating or whirling. After the resist has been hardened the roll covered with a negative 32 of the required pattern of projections is rotated once in front of a slit 33 through which light passes from arc lamps 31.

Title: Coated lead compounds
Inventor: BARROW THOMAS RICHARD
IPC: C07F7/00
Filed: 1961-11-10
Abstract: A process for providing a powdered inorganic lead compound to be used as a stabilizer for a thermoplastic resin with an even coating of a liquid plasticizer, the amount of plasticizer added to the powder being so small as to have no adverse effect on the mechanical properties of the synthetic resin, includes agitating an aqueous suspension of the powder with a solution, in a liquid plasticizer, of an organic carboxylic acid the lead salt of which is insoluble in water.  The amount of plasticizer may be between 0.5 and 8%, and the amount of carboxylic acid between 0.1 and 2%, of the weight of the powder. The carboxylic acid may be either a straight chain fatty acid containing 6 to 22 carbon atoms in the molecule, or a carbocyclic acid.  The removal of the bulk of the water from the agitated mixture and drying, crushing and powdering the resultant solid material may be effected.  If the powdered inorganic lead compound is produced by a precipitation reaction then the solution of the carboxylic acid in the plasticizer is added to it immediately following the precipitation. Lead compounds specified are basic lead sulphate, dibasic lead phosphite, basic lead carbonate and basic lead silicate. Carboxylic acids specified are n-hexoic acid, dodecanoic acid, stearic acid, mixtures containing stearic acid such as hydrogenated tallow fatty acids, benzoic acid, phthalic acid and naphthenic acid. Plasticizers specified are mineral oil, esters of phthalic acid and esters of adipic acid.  Example 1 refers to the precipitation of lead sulphate by constant stirring of an aqueous solution of litharge, acetic acid (which acts as a catalyst), and sulphuric acid.  To this suspension was added stearic acid and 2-ethyl hexyl phthalate.  The suspended matter was then filtered and dried at 100 DEG C.ALSO:Powdered inorganic lead compounds with an even coating of a liquid plasticizer, the preparation of which is described (see Division C1), are used as stabilizers for thermoplastic synthetic resins e.g. polyvinyl chloride.  The amount of plasticizer added to the powder is so small as to have no adverse effect on the mechanical properties of the synthetic resin. Lead compounds specified are basic lead sulphate, dibasic lead phosphite, basic lead carbonate and basic lead silicate.
