Title: Apparatus for generating images for display on cathode ray tubes and for transferring an image from one cathode ray tube to another
IPC: B61L25/04
Filed: 1964-11-17
Abstract: 1,093,557. Selective signalling. SOCIETE TECHNIQUE POUR L'INDUSTRIE NOUVELLE S.A. STIN. Nov. 17, 1964 [Dec. 5, 1963], No. 46686/64. Heading G4H. In a cathode-ray tube display system, train identifying members are transferred from tube to tube as trains advance from section to section. Each cathode-ray tube K1, K2, K3 . . . , Fig. 2, has a 6 x 10 magnetic core register KR1, KR2, Each cathode-ray tube K1 K2, K3 . . . , Fig. 2, KR3 . . . associated with it, each core of the register functioning both as a 1-bit store and also as a gate. Video pulse trains representing the digits 0 to 9 are produced by ten generators TE0, TEI, TE2 ... , and are applied to come sponding column conductors of all the core registers. Each generator also produces a twoout-of-five coded representation of digit being generated. The six row conductors of the core registers are pulsed sequentially by clock-pulses SS. One core in each row of each register is set in its " one " condition (these being indicated by dots) and in this condition the core couples the signals received on its column conductor to an output conductor which controls the beam intensity, whenever a signal is simultaneously present on its row conductor. Thus the sequential pulsing of the row conductors, for example of register KR3, causes the number 981018 to be displayed, digit-by-digit, on cathode-ray tube K3. When it is desired to transfer this number to a different tube, say tube K4, the output signals from the register KR3 are applied (via A31) to a common bus L1 and thence to a circuit LR which extracts the twoout-of-five coded representations of the video pulse trains being applied to the tube K3. These coded representations are transferred to a further circuit SR which recodes them, and applies them to a common bus L2 from which they pass (via E41) to, and appropriately set, any register, for example register KR4, that happens to have its input control lead coupled to the bus L2.

Abstract: 1,014,113. Securing sprockets &c. on heat exchanger rotors etc.; ratchet clutches. ROVER CO. Ltd. Nov. 16, 1964 [Nov. 27, 1963], No. 46804/63. Headings F2C and F2U. [Also in Division F4] To permit relative radial expansion &c. of two rotary members, a corrugated spring strip is provided between coaxial driving and driven surfaces, the strip comprising at least part of a circle and the corrugations being inclined to radial planes through the axis of rotation. As shown, a sprocket 4 has an inner groove containing a corrugated spring strip 5 engaging a groove 2 around the periphery of a ceramic &c. rotor 1 in a regenerative heat exchanger. The corrugations of the spring strip 5 are so inclined to radial planes through the axis of rotation, that in the normal direction of rotation the torque transmitted wedges the crests of the corrugations against the bottoms of the grooves. If the rotor &c. is accidentally turned in the wrong direction, the spring strip 5 allows overrunning. When the rotor heats up in use, the sprocket 4 being of metal expands more than the ceramic rotor 1, due to the difference in their thermal coefficients of expansion. The spring strip 5 permits the relative movement between the drive surfaces of the two grooves. In angles of inclination of the corrugations to the radial planes through the axis of rotation simultaneously altering.
