Title: Device for the locking in the locked position of an element articulated on a moving support such as a car door
Inventor: QUEVEAU GERARD
IPC: E05C19/02
Filed: 1985-03-22
Abstract: The invention relates to a device for the locking in the locked position of an element, such as a flap or casing, mounted such that it is articulated on a moving support 2, such as a door of a motor vehicle, the said articulated element 1 being normally locked in order to assume a position of use by pivoting, the unlocking being obtained by the pivoting of the said element in the direction opposite to that of its movement of release towards the position of use. This locking device is constituted by an inertia device 5 which moves between a rest position and a position in which it prevents the unlocking movement of the articulated element 1 when the moving support 2 is subjected to a sudden movement. The invention applies in particular to ashtrays fitted in the doors of motor vehicles.

Title: Microwave transceiver head, particularly for a homodyne Doppler radar system for monitoring premises
IPC: G01S7/03
Filed: 1986-03-13
Abstract: A microwave oscillator is defined by a microwave transistor Q1 equipped with tuned and coupled microwave circuits CHC, CHB and CHE. A single transceiver antenna 10 is connected to the collector of the transistor Q1, which is also connected to a load resistor R13 at the terminals of which the signal to be exploited occurs. The biasing point of the base of the transistor Q1 is defined by a capacitor C1 going to earth, and by a transfer gate, made conducting at the rate of a recurrence control signal SCR, and also connected to a resistor R11 returning to the collector. The emitter of the transistor Q1 is further connected to a variable resistor R12, followed by the collector/emitter path of a second transistor Q2 whose base is connected through a resistor R21 to the signal SCR. This enables the biasing point of the transistor to be adjusted automatically, even if the antenna is among strongly reflecting fixed objects.
