Inventor: DUCORNAIT ALBERT
IPC: G08B29/08
Filed: 1976-03-23
Abstract: The alarm and surveillance system continuously transmits a first signal. This first signal has a determined amplitude and frequency. The signal is sent along a line to which are connected a certain number of identical detectors. Each detector has in series the contact of a detector sensing variation in state and an impedance circuit. This impedance circuit is turned to the frequency of the first signal.

IPC: F24F3/14
Filed: 1976-07-15
Abstract: The method of treating air entering an air conditioner is carried out by a rotary regenerative exchanger (11) by which heat and moisture can be exchanged between air entering and leaving the air conditioner, and a humidifier (14) for adding any extra moisture required. The humidifier acts on the outlet air (B) before it reaches the exchanger.

Title: Emergency lighting system using rechargeable batteries - has photoresistor circuit preventing unnecessary discharge of batteries during daylight
Inventor: VIOLANTE ROGER FELIX
IPC: H05B37/02
Filed: 1976-10-08
Abstract: The control circuit prevents emergency lighting circuits using rechargeable batteries (Ba) being switched on during daylight hours, which could otherwise leave the system in a partially or totally discharged state at a time when it is really required. The circuit is automatic and uses a photo-resistive cell which detects the exciting light level and controls a switch in series with the emergency lighting (E). Control from the photo-resistive element is via a two transistor amplifier (B) driving a relay (L2) which operates the lighting switch. The light level at which control operates can be adjusted and the circuit itself is isolated by a series switch from the charging control circuit (A) when charging is taking place.

Patent FR-2340552-A1 (FR)
Inventor: METZGER MANFRED
IPC: G01R17/20
Filed: 1976-12-13
Abstract: In addition to the one branch (1) provided with the sensing resistor (3), the bridge has a series circuit of two potentiometers (20, 22) in the other bridge branch (18). The bridge supply voltage can be varied via a controller (27) in dependence on the voltage difference between the taps of these potentiometers. This makes independent setting of the starting and end values of the electrical measuring range possible. A further potentiometer (22') is connected in parallel with one potentiometer (22). One or the other of these parallel-connected potentiometers can be connected to the controller (27) by means of a change-over switch (30). This makes it possible to adjust the starting points of the characteristic of the measuring range step by step in accordance with a program. The bridge can be used, in particular, in controlling the charging-up of off-peak power storage heating.
