Title: Supply arrangement for two anode discharge tubes - for laser applications, avoids shunting problems arising from parallel supplies
IPC: H01S3/097
Filed: 1973-04-27
Abstract: The apparatus is designed for use in a Fabry Perrot resonator where the tube outer surface is an aluminium cathode. Two capillary tubes run the length of the resonator terminating in cylindrical anodes beyond which are the resonator mirrors. The anodes are fed via resistors to the two ends of an autotransformer centre-tapped to the supply again via a suitable resistor. In series with this supply is the auxiliary priming source connected across a rectifier. Use of the inductance ensures simultaneous excitation of the anode cathode space.

Title: Generator with vapour pressure coils - stripped electrons induce current in magnetically coupled secondary
IPC: H02N11/00
Filed: 1973-05-03
Abstract: The generator has saturated water vapour pumped under a pressure of 5 or 6 bars alternately through two oppositely sensed pipes (5, 9) wound around a toroidal laminated iron core (1). Friction produced by the fluid passing strips off electrons from the pipe inside surfaces. The pulsed or alternate flow of electrons, generates magnetic flux in the core which in turn induces an electric current in a secondary winding (2) wound around another part of the core. The fluid is injected alternately into the two pipes by a rotating disc (18) which has a single hole (19) bored eccentrically through it. The injecting pipes (16, 17) are located on one side of the disc and the inlets (11, 17) to the wound pipes on the other.
Patent FR-2228574-A1 (FR)
Title: Electric arc welding power regulator - which equalises heating of electrode and workpiece
IPC: B23K9/10
Filed: 1973-05-08
Abstract: Appts. regulates electrical power to an electric welding arc so that (a) at the start (transitory state) of a welding sequence, the arc is fed by a transitory electrical power greater than the nominal welding power, and (b) after the transitory state but before the welding sequence proper is reached; the appts. automatically, opt. progressively, ensures passage from the transitory to the permanent state. A nominal power weaker than the transitory power is used and thus feeds the arc during the remainder of the welding sequence, which is the time between lighting and extinguishing the arc, on condition that the disconnection of the arc is greater than a chosen time.

Patent FR-2263643-A1 (FR)
Title: Capacitive proximity alarm - uses capacitor between ground and amplifier input point
IPC: H03K17/16
Filed: 1974-03-05
Abstract: The device minimises the occurrence of parasitic effects by introducing a capacitor between the amplifier input and the circuit ground line. The amplifier is provided with positive feedback by a tuned base - collector coupling transformer, the base winding being connected to the proximity plate. Alternation of the circuit capacity due to a proximity effect causes the amplifier to oscillate, which in turn operates a relay and alarm or control circuit. The capacitor reduces the sensitivity of the proximity plate but this may remedied by using a transistor of high gain and/or by increasing the section of the hub of the transformer.

Title: Width modulated pulse generator for A:D converter - automatically accommodates polarity changes using differential amplifier
Inventor: SEUROT JEAN ROBERT
IPC: H03K7/08
Filed: 1975-12-09
Abstract: Generator providing an output chain of pulses which vary in width as a function of the amplitude of an incoming analogue signal. The generator is based on the use of a delay circuit and a sign or polarity detector. Input signals are transmitted through a clock source controlled gate to one input of a differential amplifier, also acting as a comparator and sign detector, via a CR potentiometer. The comparator output drives a bistable logic element controlled from the same clock source and forms part of a feedback loop to the resistive end of the potentiometer via a further gate.
