Patent FR-2439692-A1 (FR)
Title: Electronic antitheft device for vehicle - has resistance bridge connected via operational amplifier to window discriminator
IPC: G08B13/22
Filed: 1979-10-15
Abstract: The electronic warning system consists of an operational amplifier with a window discriminator at its output to produce an alarm signal when the amplifier's output lies outside given limits. A bridge circuit is used to drive the operational amplifier and it contains a voltage divider (R3, R4) as codable quiescent current loop. Different combinations of resistance and the resulting different quiescent currents preserve the output signal of the amplifier. The small quiescent current change in the voltage divider (R3, R5, R6) and a corresp. change in the output signal of the operational amplifier within the limits of the window discriminator activates the warning system.

Title: Multilayered metallised film capacitor mfg. method - uses local de-metallisations film of sections of dielectric film wound continuously on reels to trim capacitance and to form inactive layers
Inventor: BERNARD DANIEL
IPC: H01G4/30
Filed: 1980-12-31
Abstract: The method is used for mfg. multifilm capacitors in which the electrodes are attached by a flow solder technique. Edge sections of metallised film are removed from alternate sides of a strip (45) of metallised dielectric to allow correct connections of electrodes and their external terminal. For at least one pair of top and bottom layers, central sections of metallised film are also removed to electrically isolate them from the electrodes. This prevents shorting of the capacitor in the event of local shorting caused by damage to the end faces of the capacitor. Metallised sections are removed by laser cutting of ribbons of material whilst being wound into large diameter reels. Individual capacitors are then cut from the cylindrical block (41). By selecting the laser wavelength such that it is only absorbed in the metal, and by adjusting the laser power, sections of several layers deep can be removed and the capacitance trimmed to the desired value.

Title: Suspension and control of casting ladle - by an articulated parallelogram linkage
Inventor: CHATOUREL PIERRE
IPC: B22D41/06
Filed: 1981-05-08
Abstract: A casting ladle is suspended and controlled by an articulated parallelogram linkage. By this the ladle may be tilted about a horizontal axis through the pouring spout, and moved backwards and forwards in a plane through the axis. Two axes of articulation on the ladle, and that through the spout define a triangle. Links connect these to a pair of toothed wheels, freely mounted on a pivoting plate. The axes about which wheels and plate rotate form an identical triangle. A third toothed wheel of similar diameter is mounted on the pivoting axis of the plate, free relative to the plate, but fixable relative to the axis. The three toothed wheels are interconnected to rotate in the same direction. The compact and simple linkage allows the pouring spout to be positioned close to the casting hole, even when access is restricted, for improved casting conditions. The translatory motion allows the ladle to be pulled back from the pouring position for refilling.
