Patent FR-2653574-A1 (FR)
Title: Current source with low temperature coefficient
Inventor: FREDERIC BREUGNOT
IPC: G05F3/24
Filed: 1989-10-20
Abstract: The invention relates to integrated circuits, and more especially how to produce, in these circuits, a constant current source which is stable with temperature and with the supply voltage of the integrated circuit. According to the invention, it is proposed to produce a stable current source from two transistors (Q1, Q2) in parallel, one controlled by a reference voltage source of "bandgap" type (A0, R1, R2, R3, D1, D2) and the other by a "Wilson mirror" (T1, T2, T3, T4). Addition of the currents from the two transistors gives a current which can be much more temperature-stable than the individual currents in each of the transistors.

Title: Method for cleaning beaches and machine for implementation
Inventor: PHILIPPE ANDRE
IPC: E01H12/00
Filed: 1989-10-25
Abstract: The method for cleaning beaches, according to the invention, consists in carrying out a high-speed scraping operation in order to project the sand with a view to carrying out a screening/filtering operation. The machine for implementing the method includes a framework (1) mounted on wheels (2), which framework supports, on the one hand, screening/filtering means in the form of a grilled hopper (4) and, on the other hand, scraper means (5) arranged upstream of the said hopper (4). The scraper means (5), in the form of teeth (12), penetrate the layer of sand to be treated and are capable, because of the speed of advance of the machine, of spraying the sand and the debris into the screening/filtering means (4) which carry out selective sorting between the said sand and the said debris.

Title: Method and tool for the cold forging of gearwheels (toothed pinions)
Inventor: JEAN PERRIER
IPC: B21K1/30
Filed: 1989-11-07
Abstract: The invention relates to a method and tool for the cold forging of gearwheels, each toothing of which is provided with drafted side walls and with a bevelled toothing entry chamfer. The tool comprises a punch (header die) (36) having cavities (38) of shape complementary to that of the teeth of the gearwheel, a counterpunch (26) mounted so as to slide against a hydraulic pressure in a die (22) provided on its free surface with projections of shape complementary to that of the toothing entry chamfers, a stop (40) against which the counterpunch can bear when the punch is actuated, the stroke of the punch being divided into a first stroke at the end of which the punch comes into contact with the die (22), thus locking the billet (10') in a chamber where the forging will take place, a second stroke where the die/counterpunch assembly are driven and at the end of which the latter bears against the said stop, and, finally, a third stroke where only the punch and die are driven, which brings about the forging of the billet and the forcing of the metal into the cavities (38).

Patent FR-2660383-A1 (FR)
Title: Elastic support, especially for motor vehicle suspension, with highly differentiated rigidities
Inventor: MICHEL DOMER
IPC: F16F1/387
Filed: 1990-04-02
Abstract: The support includes, between the rims 10, 11 of internal 1 and external 2 reinforcing members, rigid elements 9, for example in the form of spherical steel balls, which confers very high transverse rigidity to this support, namely as regards loads tending to urge the reinforcing members 1, 2 transversely with respect to each other. In contrast, in the longitudinal direction, that is to say horizontally and perpendicular to the preceding one, the rigidity is very low, owing to the rolling and/or sliding of the elements 9 between these rims 10, 11. The vertical rigidity afforded by the elastomeric block 6 is average. The rigid elements may thus consist of blocks secured to one of the reinforcing members.

Abstract: Device for viewing, on a computer or video screen, the links created manually between video inlets and video outlet on a video cord-pairing table or between audio inlets and audio outlet on an audio cord-pairing panel. The device consists, for the video part, of three parts, a video cord-pairing table part to which a video connector, called BNC T-piece is connected, an electronic part which detects the changes in state of the video output connectors and the injection of a typical signal onto the connector which has changed state, and a computer part which, on a screen, represents the links created manually between the video inlets and the video outputs via a coaxial cable. For the AUDIO part. A cord-pairing panel part on which are mounted double female FRB connectors for the audio outputs and double FRB female connectors + a single FRB female connector for the Audio inlets. The link between an audio inlet and an audio output is made manually by a double FRB male cord which creates the link simultaneously, on the one hand, between the audio inlet and the audio output and the wires soldered to the female FRB sockets which serve as sensors for the Audio inlets and outputs. A typical electrical signal is injected sequentially onto the sensor wires of the audio inlets in order to determine whether an audio inlet has been linked to an audio output by the double male FRB cord. The computer part is identical to that described for the video part. This device applies mainly to the sector of professional radio/television.
