Patent GB-1165568-A (GB)
Title: Electronic Circuit Protector.
Inventor: ROBERTS GORDON ALFRED
IPC: H02H3/08
Filed: 1966-12-06
Abstract: 1,165,568. Protective arrangements. MECHANICAL PRODUCTS Inc. 6 Dec., 1966, No. 54629/66. Heading H2K. An overload protective system for an electronic load comprises a controlled switch and a control circuit having a time dependent characteristic for controlling the switch. The control circuit includes a current sensing device, a variable gain amplifier, and a threshold circuit effective to apply a signal to a switch control circuit. A generalized function circuit may effect full wave rectification or otherwise modify the output signal from the amplifier before its application to the threshold circuit. The switch control circuit includes an inhibiting arrangement to prevent, for approximately two cycles, operation of the system in response to transient conditions arising on the initial connection of the load. The switch control circuit, in addition to effecting the operation of the controlled switch, also controls the operation of a " generalized gain control function " circuit which, after a delay of 60 to 180 milliseconds imposed by a single shot multi-vibrator, renders the system more sensitive by increasing the gain of the amplifier. This increase in gain may be effected by lighting a lamp to change the resistance of a photoelectric cell in circuit with the amplifier. Should the lamp fail then the gain control circuit provides a signal which causes the switch control circuit to open the controlled switch. An " input on-off-reset control," e.g. a manually operable switch, may be used to control the opening and closing of the controlled switch. The whole system is formed by semi-conductor devices and is described in detail in the Specification with the aid of a circuit diagram, Figs. 2 to 5 (not shown).

Abstract: 1432787 Fire alarms CERBERUS AG 6 Dec 1973 [6 Dec 1972] 56500/73 Heading G4N [Also in Division G1] In a fire detector simultaneously measuring two different characteristics of smoke or other gaseous products of fire, the smoke &c. enters the chambers 2, 5 and 6 of the fire detector via entrance 3 and the radiation absorptive effect and the scattering effect of the smoke &c. is detected by two detectors 8 and 7 respectively. The detectors outputs are fed via amplifiers 10, 11 to respective threshold circuits 12, 13 which only pass a signal when detector 8's output drops below a predetermined value and detector 7's output rises to above another predetermined level. The threshold circuit's outputs are gated via an AND gate 14, a timing circuit 15 and a switching circuit 16 to actuate the alarm. Thus the alarm is only activated when both characteristics of a fire are detected. The detectors may be photo diodes and the source may be semiconductor laser or light emitting diodes. One or more sources may be used.
