Title: Data transmission arrangements
IPC: G06F13/42
Filed: 1969-02-27
Abstract: 1,224,436. Transfer between data stores. SIEMENS A.G. 27 Feb., 1969 [28 Feb., 1968], No. 10658/69. Heading G4C. In a data transmission arrangement, a logic feed-in circuit passes to the input of a receiving shift register either the output of a transmitting shift register or the output of the receiving shift register depending upon the output of a mask shift register, as the three registers are shifted in synchronism, whereby the data at locations of the transmitting register determined by the content of the mask register will be transmitted to corresponding locations of the receiving register. The output of the logic feed-in circuit may also be inserted into the input end of the mask register, and the output of the receiving register also inserted into the input end of the transmitting register. The transmitting and mask registers and the logic feed-in circuit are at a transmitting station and the receiving register is at a receiving station. Each 1 from the logic feed-in circuit reverses a first parity trigger at the transmitting station and a second parity trigger at the receiving station, the states of the two triggers being continuously compared at the receiving station to produce an error signal (e.g. to produce repetition of transfer) if unequal. As a modification, the inputs to the mask and transmitting registers above could be interchanged. A second embodiment differs from the first in having a plurality of receiving stations, addressable from the transmitting station. The logic feed-in circuits are in the receiving stations, and the triggers used in the error checks are fed from the output of the transmitting shift register instead of the logic feed-in circuit. A third embodiment permits any selected one of a plurality of extra registers at a receiving station to exchange data with the transmitting shift register via the receiving shift register, data transfer between the extra registers and the receiving shift register being parallel by bit.

Abstract: 549,503. Commutators of dynamo-electric machines ; brazing. ENGLISH ELECTRIC CO., Ltd., and ROBERTS, L. Sept. 10, 1941, No. 11599. [Class 35] [Also in Group XXII] The flat-faced armature conductors 3 are brazed to the thin upstanding risers 1a of the commutator segments by interposing a strip of silver solder foil or phosphor-copper foil between the adjacent parts, applying electrodes to the two parts near their juncture and passing a heavy current through the joint so that the heat is confined substantially to the joint and does not adversely affect the insulation. The mica insulation 2a between the commutator segments is cut back in the neighbourhood of the joint so as to afford better access for the electrodes. After the joint is made, packing pieces of insulating fabric, which may be pre-moulded to shape, are inserted in the gaps between the risers and between the conductors. The gaps between the overhanging parts of the bared conductors 3 may be covered by a bag or wrapping of heat-resisting insulating material such as asbestos or woven glass, or by a plastic paste containing mica dust all held in position by an enveloping insulating sleeve 4. As a further means of excluding dust, additional lugs 1c of full thickness may extend from the segments to form a solid ring closing the end of the armature. Alternatively, the end may be closed by a ring of moulded material keyed to the segments.

Class 40 (4) Corresponding test outlets of line finders OZ and final selectors EK are interconnected by a star or equivalent delta network of resistors R1 R2, R3, which are connected to a common potential VI of -60 volts and are so chosen that individual line finder and final selector outlets exhibit characteristic identification potentials in the ranges -32 to -60 volts and -28 to 0 volts respectively when the outlets are tested. The identity of line finder outlets is determined by a register (not shown) which tests the potential over a resistor R5 and busies the calling outlet by closing contact b. The corresponding final selector outlet then exhibits the correct identification potential between -28 to 0 volts instead of V1, and indicate a busy condition as well as permitting identification of the outlet by a register. Free final selectors initially have a potential V1, and the correct identification potential does not appear until a resistor R4 is connected in series by the register. A resistor of the same value. as R4 is connected to the outlet for the duration of the call to maintain a busy condition. Specification 647,073 is referred to.
