Title: Improvements in or relating to means for the transfer of information in circuits incorporating magnetic cores
IPC: G11C19/04
Filed: 1957-08-28
Abstract: 863,069. Circuits employing bi-stable magnetic elements. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Aug. 28, 1957 [Sept. 24, 1956], No. 27123/57. Addition to 825,949. Class 40 (9). [Also in Group XIX] In a shift register substantially as described in the parent Specification, windings of auxiliary saturable cores 55A, 55B, &c. are connected in the condenser circuits between the storage cores (1) and (2), (2) and (3), &c. When a core (2) is shifted from state P to state N as a bit is stepped on from core (2) to core (3) via a condenser 4B, the auxiliary cores 55A, 55B are so controlled by the three-phase driving pulses Ia1, Ia2, Ia3, Fig. 3, as to present respectively a high impedance and a low impedance. The greater part of the energy from the change of state P to N is thus transmitted in a forward direction. For example, core (2) is transferred from P to N by the positive pulse of Ia2, digit 1 being represented by P and 0 by N. Core 55A is driven from N to P at the same time and presents a high impedance in the charging circuit of condenser 4A. Core 55B is held saturated at N by the positive pulse Ia1 which still persists and presents a low impedance to the current charging condenser 4B. Core 55A is restored to N by a positive pulse Ia3 when the bit is stepped on from core (3). The stepping register shown in Fig. 8 uses two-phase control currents In1, Ia2, Fig. 7. The control currents for the auxiliary cores may be shaped as at Is1, Is2 to reduce the currents which auxiliary core 55 produces in opposition to the condenser charging currents produced by core 2. Alternatively resistors may be connected in parallel with the auxiliary cores.

Filed: 1923-11-02
Abstract: 215,271. Hughes, T. O., (Caillau, M. U.). Nov. 2, 1923. Clips, band.-In a band clip of the type in which one end of the clip engages a slot in a winding pin mounted in the loops of a shackle on the other end of the clip, the winding-pin a is a solid cylindrical piece of metal with a slot b extending from one end, the diameter of the pin being slightly greater than that of the loops n of the shackle so as to open out the ends l of the shackle when placed in position. The ends d of the pin are rounded to facilitate insertion and the mouth of the slot is flared outwardly. The head e of the pin may be of any convenient shape and has a hole f for a turning tool and a slot g for a screw-driver. Tightening of the clip causes the overlying ends A, A' of the band to press the ends l of the shackle together and consequently tightens the loops n on the pin. The two halves of the pin also become drawn together and their resiliency tends to maintain the pin in position. To release the clip, the pin is slightly unwound, when the tension on the ends l of the shackle and also on the prongs of the pin is relaxed so that the pin may be withdrawn from the loops without further unwinding, and reinserted when again required.
