Patent FR-2288413-A1 (FR)
Title: Stabilised DC power supply unit for computer - uses two regulation control loops in chopping circuits
Inventor: GAUTHERON JEAN-FRANCOIS
IPC: H02M3/337
Filed: 1974-10-17
Abstract: The main input to this power supply unit is rectified, filtered and then connected to two chopping-circuits in series. The first has a control loop from its output via a control interface which modifies clock-pulses from a clock-generator. This compensates for mains variations. The second has a control loop from the final output via another control interface. This compensates for output load variations. The use of two loops gives better stabilisation than with one loop controlling input and output variations.

Title: Single-buffer type automatic coupling - has locking devices breaking at specific points under excessive load
IPC: B61G3/12
Filed: 1975-04-25
Abstract: The coupling is particularly for rail vehicles, having components destroyed under excess loades. The locking devices (2, 21) are designed so as always to break at specific points, their section being such as to fail when a maximum tractive effort is exceeded, being typically of box-section with hollowed-out portions and/or anti-friction ribs (6, 61). The failure of the locking devices allows the catches (5, 51) associated with shock absorbers to move towards each other in the directions of arrows (A), with the result that the catches move from their support surfaces. The locking devices may be channel section with cut-outs on their webs.

Title: Continually running self-acting air motor - has evacuated hollow turbine with sprung discs slidable in inclined cylinders at periphery
IPC: F03G7/10
Filed: 1976-02-26
Abstract: The engine has a hollow turbine wheel whose walls hermetically seal a closed space in which a vacuum has been formed. The sides of the turbine are conical and reduce in thickness from the axis to the circumference. The circumference carries four equally spaced discs set at an angle to the wheel. Each disc slides in a cylinder perpendicular to the turbine wheel in which it is held by a spring within the cylinder. A cylindrical casing surrounds the turbine to define an annular space. An initial charge of compressed air is admitted into this space. Its pressure on the springs rotates the turbine, and the vacuum inside the turbine ensures that the action repeats itself.

Title: Electrolysis of chlorides of alkali metals forms metal amalgam - which are pumped through decomposing induction motor
IPC: C25B1/42
Filed: 1976-04-22
Abstract: A process and a plant installation are claimed for the electrolysis of chlorides of alkali metals. Electrolysis takes place in a cell inclined to the horizontal and having an inlet for mercury at the upper end and an outlet for amalgam at the lower end, the discharged amalgam being transferred into a decomposing chamber or reactor beneath the cell where amalgam is decomposed by water in the presence of graphite as catalyst. The reactor has inlets for amalgam and for water and outlets for caustic soda and for mercury being returned to the upper end of the cell, the mercury being displaced by the moving electromagnetic field of a linear induction motor forming part of the reactor, the displacement serving both to mix and agitate fluids in the reactor and also to pump mercury back to the cell. The decomposing chamber or reactor is pref. made in nonmagnetic steel or plastic such as P. T. F. E. and scoped at an inclination of 10 mm/m. The linear motor is disposed longitudinally of the reactor and comprises a laminated core within electric windings. When the amalgam is sodium amalgam the sodium content is pref. about 0.01% to 60% by weight and the decomposing process pref. takes place at a temp. between 20-120 degrees C. Industrial electrolysis of chlorides of alkali metals such as sodium and potassium, producing caustic soda, caustic potash etc. as well as hydrogen. The moving field of the linear motor creates agitation in the reactor and reduces decomposing time substantially. The elimination of mechanical pumping avoids associated problems of heavy wear, servicing and downtime.

Title: Wireless telephone conversation amplifier - uses magnetic field of receiver to cut coil connected to limited gain amplifier and loudspeaker circuit
IPC: H04M1/62
Filed: 1977-05-31
Abstract: The telephone conversation amplifier has a magnetic winding which is large enough to permit amplification of the conversation by simply placing the amplifier by the side of the receiver. The amplifier is sufficient directive with respect to the telephone receiver. The axis of the magnetic field is 90 deg. with respect to the axis of the loudspeaker coil so as to prevent feedback. The gain of the amplifier is limited and non-adjustable to prevent Tarsen effect. The amplifier circuit uses a weighted plate acting on a pushbutton or lever to open or close the amplifier circuit.
