Title: Improvements in or relating to electronic counters and the like
IPC: H03K23/00
Filed: 1960-02-26
Abstract: 917,544. Transistor bi-stable circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 26, 1960 [Feb. 27, 1959], No. 6851/60. Class 40 (6). [Also in Group XIX] A counter having bi-stable (conductive or non-conductive) transistor stages V1, V2 . . . Vn, has in each stage an inductive circuit L connected to an input of the next stage and in which current flows when its associated stage is conductive, stepping pulses being applied to all stages in parallel to series connected capacitors C2 and rectifiers D2, the common point of the capacitor C2 and rectifier D2 of a stage being connected to the preceding stage in such manner that, if the preceding stage is conductive, the rectifier cannot conduct the stepping pulse. In each stage the base of a PNP transistor T1 is connected to the collector of NPN transistor T2 and the base of T2 to the collector of T1 so that conductivity in one transistor increases conductivity in the other until both are saturated. The emitters of transistors T2 are connected to supply - E3 (- 12v) through a load R9 such that only one stage is conductive at a time. The collectors of transistors T2 are connected to earth through inductance L and to the common point of the capacitor C2 and rectifier (diode) D2 of the next stage through resistance R7. Inductance L is connected to the base of transistor T2 through capacitor C1. Assuming stage V1 to be conductive the potential of the collector of transistor T2 charges capacitor C2 of stage V2 to prevent conduction by diode D2 of the positive stepping pulse which is however applied to the bases of the remaining transistors T1, stage Vn being connected to stage V1, to send stage V1 non-conductive and cutoff current through inductance L. The countere. m. f. of the inductance is then applied to the base of transistor T2 of stage V2 sending it conductive. A delay may be introduced at point A between adjacent stages, in which case to maintain point C at a high potential to prevent the bi-stable circuits from becoming conductive during the delay time a diode is connected between C and the line - E2 in a direction which renders it blocked when any of the stages are conductive. A circuit is described (Fig. 2, not shown), in which this diode is replaced by the base and emitter of a transistor, the collector of which is connected through an integrating circuit to the base of a further transistor which when conductive renders conductive a selected stage of the counter. This further transistor conducts when the counter is initially connected up or when there is a drop-out of stepping pulses. In a modification (Fig. 3, not shown), the energy of the inductance L is stored in a capacitor from which it is released, by a second timing pulse, across an inductive coupling to send the next stage conductive.

Abstract: 161,806. Blunt, R., and Mitchell, H. F. March 13, 1920. Mine signalling systems.-In signalling systems, especially for mine signalling, a switch is employed comprising an operating lever, which, as it is swung on its way to close a main signalling circuit, closes, momentarily, an auxiliary signal-cancelling circuit. As shown in Figs. 3 and 5, the switch has an operating lever d secured upon a spindle e journaled in the side walls of the casing and carrying a blade contact f and a cam h with the relative dispositions shown. To close the main signalling circuit, the operating lever is brought to the position substantially vertically over its pivot whereupon the contact f bridges the fixed contacts g; if released, the lever falls by its own weight. In the closing movement the cam h rocks an intermediate lever j which may carry a roller o and is normally maintained in the central position by the springs k. The roller o engages a spring arm contact m and presses it into engagement with a companion contact n to close the auxiliary circuit. Subsequently, and before the main circuit is closed, the cam passes away from the roller and the auxiliary circuit is broken. When the operating lever falls, the cam h rocks the intermediate lever j away from the auxiliary contacts so that these contacts are not closed.
