Patent GB-793077-A (GB)
Abstract: 793,077. Calculating-apparatus. AKTIEBOLAGET ATVIDABERG-FACIT. Feb. 23, 1956 [Feb. 28, 1955], No. 5684/56. Class 106 (1) In a machine in which the process of division is automatically controlled, the means controlling the denomination shifting mechanism is rendered ineffective during substantially the whole of the first cycle following re-setting of the dividend register. Thus, a reciprocal may be computed without first entering a unit into the dividend register. The invention is applied to the cam-disc and pin-wheel machine described in Specification 551,311 in which denominational shifting of the actuator is effected under the control of a bail 8 which is rocked by operation of the tens transfer hook 7 of the highest order, a pawl 4 coupling the two members during division. The pawl 4, instead of being mounted directly on a division control arm 3, is now carried by a plate 1 pivoted on that arm and having a cam slot engaged by a finger of a plate 9. A cam 13 is rotated when the dividend register is re-set and rocks the plate 9 into the position shown so that the plate 1 withdraws the pawl 4 from beneath the bail 8. Thus when the hook 7 operates during the first subtraction cycle of the division, the bail 8 is not rocked and further subtractive cycles follow. At the end of the first cycle, a cam 11 on a shaft 12 which rotates with the actuator restores the plate 9 so that when, the hook 7 next operates, the bail 8 will be rocked and normal division operations will follow thereafter. A detent 15 holds the plate 9 in whichever position it assumes.

Patent GB-796379-A (GB)
Abstract: 796,379. Preventing inductive disturbance. SIEMENS & HALSKE AKT.-GES. April 4, 1956 [April 4, 1955], No. 10309/56. Class 40 (4). In a system in which three-phase power is fed to distant exchanges or repeater stations over coaxial conductors in a cable also comprising additional interstitial circuits, inductive interference in the latter is avoided by arranging the coaxial cables in such a way that different groups of the cables produce rotating fields, the resultant of which is zero. Thus in a preferred embodiment six coaxial cables are symmetrically disposed with respect to the centre and if these are numbered 1 ... 6 sequentially along the circumference, then numbers 1 and 4 are 2 and 5, and 3 and 6 are commoned for the purpose of carrying the three phases. The fields due to the systems 1, 3, 5 and 2, 4, 6 are thus equal and opposite.
