Abstract: 699,052. Bichromated colloid plate for planographic printing. TICKNER, A. (Columbia Ribbon & Carbon Manufacturing Co., Inc.). Oct. 9, 1951, No. 23504/51. Drawings to Specification. Class 98 (ii). A plate has a paper foundation, an insolubilized coating of a carboxymethyl cellulose compound therein and, adhering to the surface of the latter, a bichromated albumin coating. The plate may be exposed under a negative, if desired using a half-tone screen, and washed to remove unexposed areas, or, after exposure, may be coated with asphalt or gilsonite solution and submerged in dilute aqueous ammonia; to produce a planographic printing plate in which the ink-receptive portions penetrate sufficiently into the carboxymethyl cellulose to remain firmly bonded thereto during printing operations. Preferably the paper foundation is made resistant to swelling or deformation, as by incorporating a melamine- or urea-formaldehyde resin in the pulp used for making the paper or by coating the paper with a water-proof lacquer such as a polystyrene resin in a solvent, or a casein-formaldehyde solution. An aqueous solution of an alkali salt or an ammoniacal aluminium salt, of carboxymethyl cellulose, and which may contain up to 20 per cent of other colloids such as sodium alginate, alkali casein, or zein and also a filler such as colloidal clay and a plasticizer such as glycerin, is applied in one or more coatings to the paper and insolubilized as by treatment with a copper, ferric or chromic salt, glyoxal, or a strong acid solution or by evaporating off ammonia when this is used. After drying bichromated glue or egg albumen is applied as by whirl coating and then exposure and processing are by normal methods. Four examples provide quantitative details. The use of coatings of casein-formaldehyde, polyvinyl alcohols and carboxymethyl cellulose compounds for similar purposes is referred to.

Title: Improvements in or relating to electronic digital computing machines
Inventor: STRACHEY CHRISTOPHER
IPC: G06F7/52
Filed: 1953-08-27
Abstract: 796,404. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 25, 1954 [Aug. 27, 1953], No. 23735/53. Class 106 (1). In an electronic digital computing machine adapted to operate in a series mode and employing circulating delay line storage registers, apparatus for carrying out the process of multiplication, Fig..9, comprises three such registers each of one word length and each provided with its own circulation loop, an adding circuit 172 connected in the circulation loop of one of said registers (accumulator register ACC1), a gate circuit 173 connected between another of said registers (multiplicand register D) and said adding circuit, means for controlling said gate circuit, said means comprising a control circuit 174 connected between the third of said registers (multiplier register R) and said gate circuit and a transfer circuit 175 for transferring digit signals from said accumulator register to said multiply register. A multiplicand D is repeatedly added to an accumulator register ACC1, the contents of which shift one digit to the right in the direction of decreasing significance each word time, under the control of the digits of a multiplier R, the current multiplier digit being held for one word time in a statisizer 174. As successive digits of the multiplier are used to control the additions of the multiplicand, they are destroyed and in their place, left-hand end of R, are put the digits that overflow from the accumulator as its contents shift to the right. Thus, finally all the multiplier is used and destroyed and the required product, being two words long, is held in R and ACC 1. The apparatus described employs signed numbers, the sign digit occupying the position of highest significance, and to take this into account during multiplication the adding circuit 172 is arranged to subtract during the word time in which the sign digit of the multiplier is the current digit. The detailed arithmetic circuit is similar to that described in Specifications 789,207, 789,208 and 789,209, all of which are referred to.
