Abstract: A three color gun cathode ray tube has convergence correction signals derived from digital signals stored in a digital data store. The screen of the tube is divided into a plurality of areas and a digital correction signal derived for each area. The system is arranged so that when the three beams are scanning a particular area the digital correction signal associated with that area is read out from the digital store, passed through a digital to analog converter and then applied to the convergence coils of the tube.

Abstract: 1,128,576. Electric digital calculators. INTERNATIONAL BUSINESS MACHINES CORP. 29 July, 1967, No. 34961/67. Heading G4A. In a multi-word data store capable of performing logical operations, bit conductors are each connected in common to the bit storage devices occupying corresponding bit positions in each of the word locations, and a plurality of majority logic gates each connect a different pair of adjacent bit conductors and produce a signal on one of the pair when the signal level on the other of the pair exceeds a threshold. Correspondingly - positioned bits of two words read simultaneously from respective rows of a matrix store are added on the column read-write lines. If the sum on a given column line exceeds 1, a threshold (majority logic) gate respective to the column adds 1 to the adjacent column line. In this way carries can be propagated during addition of two words (with end-around-carry in the case of twos-complement subtraction). After carry propagation, the sum (or difference) of the two words is obtained by a level discriminator circuit which in the case of each column line, produces a 1 output if the signal on the line is 1 or 3. Fig. 3 shows two words of the store utilizing cross-coupled pairs 6 of two-emitter transistors, each threshold gate being a transistor longtailed pair 7. The sum may be obtained, after carry propagation as above, without use of the level discriminator circuit, by a sequence of complementings, storings, majority operations (using the threshold gates and reading out three words simultaneously in each case) and shift (using an external shift register), which is described.
