Patent GB-732028-A (GB)
Abstract: 732,028. Two-way transmission. SVENSKA RELAFABRIKEN AKTIEBOLAG. Oct. 14, 1953 [Oct. 15, 1952], No. 28395/50. Class 40 (4). In a loud-speaker inter-communication system including voice controlled means for keeping either channel of a two-way amplifier blocked to avoid howling, further manuallyoperable means for the alternate blocking and unblocking of the respective channels is provided in the telephone sets. Station A, Fig. 1, is connected to station B over a circuit including connecting relays AR and BR at the calling and called stations respectively and a pair of amplifiers FI, FII. Relays AR and BR are operated in conjunction with a selecting switch. Blocking and unblocking is manually controlled by a key TK which operates relays TR1 and TR2, the former of which is self-locking, and the manual control may be used if the ambient noise level at one of the stations is so great as to prevent operation of the voice control. Contact 1 of relay TR1 is connected in series with contact 1 of relay TR2 across the input of amplifier FI, and contact 2 of relay TR2 is connected across the input of amplifier FII. Relay 2 which responds to each operation of key TK can therefore effect directional control as required. The locking circuit of relay TR1 is arranged to open at the conclusion of a call. Modified arrangementa using relays to open circuit the amplifier input in the unwanted direction or to earth the grid of the unwanted amplifier are described with reference to Figs. 2 and 3 (not shown). The latter embodiment is intended for use at a station where there is a permanent high ambient noise level and the relay TR1 is energized by a further contact on the relay AR when a call is made.

Title: A circuit-breaker having a mechanical delay device
IPC: H01H7/03
Filed: 1979-06-11
Abstract: A circuit-breaker provided with an oscillating weight delay device comprises a slide 22 carrying first and second contact bridges 24 cooperating with respective fixed contact pairs 28 and 32. The slide is urged into a lower position, to close a circuit through contact 28 and bridge 24 and to open a circuit through contact 32 and bridge 26, by a spring 40 and bell-crank lever 48. Slide 22 is moved upwards by a push rod 20 on actuation of the circuit-breaker to open the circuit through contact 28 and bridge 24 and close the circuit through contact 32 and bridge 26. Slide 22 cooperates with a lever arm 60 which transmits an impulse to rotary weight 64 when the slide begins to move. During its oscillation, the weight loads a spring 68 which subjects the slide to an upward resilient contact-closing force. The duration of the oscillation of the weight determines the time for which the contact bridge 26 is held in the closed position and the return motion of the slide is started by a lug 66 on the weight striking the slide. <IMAGE>
