Title: Improvements in or relating to storage arrangements, particularly for type printing telegraph apparatus with storage of the signals to be transmitted
IPC: H04L13/08
Filed: 1952-05-26
Abstract: 704,594. Type-printing telegraphy. SIEMENS & HALSKE AKT.-GES. May 26, 1952 [June 27, 1951], No. 13292/52. Class 40 (3) In type-printing telegraph apparatus an arrangement for storing the signals to be transmitted comprises storage members arranged to be radially displaceable in a drum and annular elements, entirely or partially surrounding the drum, which are mounted to be displaceable in the direction of the axis of the drum and have extensions sensing the storage members for the signal so that the temporary positions of the said element are characteristic of the elements of a stored signal. Pins 7 frictionally mounted in a drum 5 rotatable on a shaft 1 are selectively set by levers 12 coupled to combination bars 9 moved by the key levers 8. The levers 12 are moved upwardly to push in the appropriate pins by a cam on a shaft 13 carrying a further cam 14 rocking a lever 16 having a pawl 17 which engages a ratchet wheel 6 secured to the pin drum. The shaft 1, which is arranged to be stepped forward with the drum, is integral with a cam 2 which is connected by a link 18 to a spring 19 and carries brackets 3, 4 which support rods 28 ... 32 on which are mounted sensing members 23 ... 27, the member 23 being rigidly attached to the rod 28 and sliding on the other rods, with a similar arrangement for the other members as indicated more clearly in Fig. 2. During rotation of the shaft 13 a ratchet arrangement (not shown) allows a small rotation of the shaft 1 in the direction opposite to that of the pin drum, and the shaped ends 23a ... 27a selectively engage the pins so that a pin which has not been depressed moves its associated sensing member 23 to the right and unblocks the arm 21a so that a contact lever 21, when released by a cam 36, can close contacts 22, the levers 21 being released in sequence. A cam member 37 within the drum restores the pins 7 before they reach the position in which they are set by the keys 8, and the members 23 ... 27 are restored to their normal positions by springs 34 engaging collars 35 on the respective rods. In a modification, Figs. 3, 4 (not shown), the segmental members 23 ... 27 of Fig. 2 are replaced by complete rings, and the pins are held in their adjusted positions by springs located in axial bores in the drum. In a further modification, Figs 5, 6 (not shown), five sets of pins are radially mounted in two coaxial hollow cylinders with a separate circular spring engaging opposite sides of consecutive pins of each of the circularlyarranged sets of pins

Abstract: 1,078,906. Vacuum switch. GENERAL ELECTRIC CO. March 28, 1966 [May 28, 1965], No. 13523/66. Heading H2B. A vacuum switch has a fixed annular contact 17 surrounding a movable contact 18 with, in the open position, an annular gap 22 between them in which the arc is struck and means producing a radial magnetic field in the gap of sufficient strength to substantially reduce the arc voltage. The fixed electrode 17 is supported on a copper helix 40 whose turns are spaced apart by relatively high resistance stainless steel inserts 44. In order that the radial field shall reduce to zero at current zero and thus not interfere with the extinction of the arc, the electrodes 17, 18 are slotted (62, 64) and electrode 18 is perforated (65) (Figs. 1a, 2, not shown) to reduce eddy currents, and low permeability, high resistance, stainless steel end plates 12, 13 are employed for the evacuated envelope 10. In a modification (Figs. 4, 5, not shown), the pivotally mounted movable electrode (18b) is also carried by a helix (40b) the fields of the two helices interacting to produce a strong radial field in the gap 22. The helices 40, (40b) are each connected to the electrodes 17, (18b) at one point only adjacent to the slot 62 and the slots 64 in electrode 18 are curved so as to create a circumferential field to move the arc around the annular gap 22.
