Title: Lithographic plates
IPC: B41N3/03
Filed: 1964-02-07
Abstract: 1,020,648. Printing plates. A. B. DICK CO. Feb. 7, 1964 [Feb. 7, 1963], No. 5305/64. Heading B6C. [Also in Division G2] A method of manufacturing a lithographic plate of an amphoteric metal comprises the steps of thoroughly cleaning the surface of the metal plate, treating the cleaned surface with an aqueous solution of polyacrylic acid and rinsing the treated surface with water. In the described Example I aluminium sheet is cleaned in a precleaning step, to remove oils, greases, smut or other materials collected during the rolling steps of sheet manufacture, by passing up to six times through a bath of 20% by weight of trisodium phosphate, 1% by weight of sodium gluconate and 79% by weight of water which is maintained at about 175 F. After rinsing with water, or other suitable aqueous medium, smut formed on the aluminium surface by the alkaline solution of trisodium phosphate is removed in a bath of concentrated solution of nitric acid. The aluminium is again rinsed prior to passing through a bath of solution containing 0À1 to 1À5% by weight of polyacrylic acid wherein the cleaned metal is exposed to the acid for between 15 and 300 seconds at between 150 and 212 F. The treated aluminium is then rinsed with water and air dried. Plates formed from the sheet may be imaged by means of a lithographic typewriter ribbon or transfer sheet having a coating of an ink receptive, waterrepellent imaging material for die impression or stylus work or by a lithographic ink, crayon or pencil. Plates formed from the sheet may also be used as photolithographic plates by coating the treated surface with a light-sensitive material that is reduced to an ink-receptive, water-repellent, imaged material in the areas of the coated plate that are exposed to the light. A suitable material is a composition of 0À1 to 2À0% by weight of paradiazo diphenyl amineformaldehyde condensate, 10% by weight of acetone, 0À2% by weight of wetting agent, 0À24 to 0À36% by weight of a stabilizer such as citric acid and the remainder water. Instead of aluminium other amphoteric metals such as copper or zinc may be used. These metals may be employed when laminated to a suitable backing such as paper or plastic.

Abstract: 644,478. Helicopter rotor blades. PREWITT, R. H. Feb. 24, 1948, No. 5468. Convention date, Jan. 28, 1947. [Class 4] A rotor blade for a helicopter comprises a main structural member shaped to conform to the leading edge of the aerofoil, chord members extending toward the trailing edge of the aerofoil and a cover enclosing and attached to the main and chord members. The main member is hollow, the wall thickness increasing from the tip toward the root 2 where the section becomes annular and is reinforced by a collar 6 welded to it. Chord members 21-24, 44 are attached to and extend between the rear wall 31 of the main member and a trailing edge member 25. A thin sheet 4 of stainless steel or like metal surrounds, and is adhesively attached to, the leading edge and rib members. Hot gases for de-icing purposes enter the blade via a flexible tube 55 (Fig. 2, not shown), and a manifold 15, Fig. 1. At a predetermined temperature of the blade or of the gases a thermostat 29 operates a member 30 and allows hot gases, previously confined to a chamber 19 at the root, to flow through holes 18, unimpeded by plates 36, into the structural member 3 where they are forced by centrifugal action to the blade tip and exhausted through a vent 20 normally closed but constructed to open when the internal pressure rises. A weight 8 is pivoted at 9 to the blade tip and may be adjusted by a screw 10 to move the blade centre of gravity in a chordwise direction whilst manufacturing errors in the longitudinal balance may be compensated by changing this weight. Fig. 2 (not shown) illustrates a helicopter having one rigid and one flapping blade.
