Title: Improvements in electric fly switches
IPC: H01H15/02
Filed: 1920-04-29
Abstract: 170,873. Damey, C. A. April 29, 1920. Switches, quick-break, have a reciprocating push 15 carrying a sheet-metal cam 17, which passes through a slot 14 in the member 10 carrying a bridge-piece 11, which may connect the contact 2 or 3 to the contact 4. A spring 52 is interposed between the bridge 11 and the insulating base 1, and presses the lower of a series of antifriction balls 13 contained in the hollow end of the member 10 against the cam 17, thereby producing a quick switching action after the push 15 has been moved to the right, Fig. 2, sufficiently to bring the ball 13 opposite the inclined portion of the cam 17. The construction may be modified to give lost motion between the push 15 and the cam 17, and between the member 10 carrying the balls and the member carrying the bridge 11.

Title: Improvements in or relating to electric oscillation generators
IPC: H03K3/10
Filed: 1945-05-12
Abstract: 595,509. Valve generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd., WHITE, E. L. C., and WALKER, D. [Representative of BLUMLEIN, A. D.]. May 12, 1945, No. 11985. Addition to 535,778. [Class 40 (v)] The cathode coupled multivibrator circuit of the parent Specification is modified to provide one stable and one unstable position, the change from the stable position being effected by the application of a controlling impulse. A multivibrator circuit is shown in Fig. 1, the cathode impedances R3, R4 being such that no grid current flows. A diode 3 connected in parallel with condenser C between the cathodes, holds valve 2 quiescent by preventing the potential of the cathode falling below that of valve 1 (bias potentials being appropriately selected) so that a stable state exists with valve 1 conducting. If a negative trigger pulse is applied to the grid of valve 1, valve 1 cuts off and valve 2 starts conducting. The normal multivibrator cycle continues until the stable state with valve 1 conducting is again reached. A modification avoids the use of diode 3, the difference in bias applied to each valve being sufficient to make the condition stable when valve 1 is conducting and valve 2 is cut off. A diode may also be placed across the input resistor R1, when positive trigger pulses may be applied. A further modification (Fig. 5) provides for a short-circuited delay network 6 to be included in the anode circuit of valve 2, to shorten the pulse width, and for a further diode 5 to be connected between the grid of valve 2 and a source of bias potential which speeds up the discharge of condenser C1, thus reducing the period before the circuit is again sensitive to the trigger pulse. The valves may be in one envelope, and the resistor R5 may be replaced by a valve normally conducting but capable of being rendered non-conducting on receipt of a pulse to its control electrode. The circuit may be used as a low ratio frequency divider in the manner described in Specification 456,840.
