Patent FR-2295508-A1 (FR)
Title: Galvanic isolation of two electrical measuring networks - using optical counter and photo transistor operating in saturated mode
IPC: G01R17/04
Filed: 1974-12-20
Abstract: Galvanic isolation of two electrical measuring networks is performed using an optical counter. A ramp generator, made up of an operational amplifier (1) and a zero reset device (2), furnishes a ramp signal linearly symmetrical with a zero potential point (earth). An operational amplifier (3) compares the ramp signal and the measuring signal. For a null measuring signal the comparator supplies as output, a symmetry signal. When the measure signal increases the output of the comparator becomes asymmetric. The output of the comparator directly feeds the photoemitting diode (4) of the optical coupler. The association of the phototransistor of the coupler with the operational amplifier (6) permits restitution at saturated level of the output signal of the comparator (3).

Patent FR-2290282-A1 (FR)
Title: Veneer sheet drier automatic loading machine - has perforated belts running below vacuum chambers to transport sheets
IPC: F26B25/00
Filed: 1975-02-07
Abstract: The machine automatically loads the moistened sheets in a belt- or roller-type drier, and unloads and stacks them when dried. It has chambers (C1, C2) with perforated bases, in which a vacuum is generated by a suction fan. A set of belts, likewise perforated, run underneath the chambers. Thus the air drawn in through both sets of perforations causes the sheets delivered from time to time to adhere to the belts, which transport them forward. The intake chamber can have a feeler and a number of rams offset from it, with a micro-switch at a set distance from the rams. The stack of sheets is accommodated on a hydraulic, electrically-controlled lifting platform, and is halted a few centimetres clear of the belts by the feeler. On the command from the micro-switch the rams are lifted so as to exert a vacuum on the topmost sheet pulling it against the belts, as soon as the previous one has passed the micro-switch. Thus sheets are automatically delivered in succession to the drier conveyor.

Title: Electronic stop switch controlling advance of sharpening tool - uses coincidence of metal surface with plane formed by tips of three charged point electrode
Inventor: LAVERGNE
IPC: G01B7/30
Filed: 1976-04-02
Abstract: The electronic stop may be used to control the advance of the tool or the workpiece on tool-sharpening machines, and controls the motion of a metallic surface (B) relative to a reference plane (A). The reference plane (A) is defined by the tips of three non-aligned and electric-charged metal points (P1, P2, P3). A control unit (2) monitors the simultaneous conductivity of the three points which occurs when all three are contacted by the moving metal surface (B). The system eliminates the play associated with mechanical stops, and effects limitations of relative motion when the said simultaneous conductivity occurs. The stop may also be used to control the angular position of cutting tools on sharpening machines.
