Patent FR-2524419-A1 (FR)
Title: Packing of unit in cardboard box threaded on from above - entails folding certain flaps outwards and then inwards after part conveyor retracted
Inventor: DAUBREMET GEORGES
IPC: B65B7/20
Filed: 1982-04-06
Abstract: The process entails packaging without lifting the product e.g. a washing machine (2) in a cardboard box (3) with flaps (33). A conveyor with retractable sections feeds the product onto a stand (4) where the box is threaded onto it from above. Next the lateral bottom flaps are folded inwards and the bottom longitudinal flaps temporarily outwards, the subsequent phase using the conveyor to take the assembly away from the stand whilst maintaining the flaps in the first folded state. The longitudinal flaps (33) are finally freed by retracting certain conveyor sections (10), then being folded inwards by displacing the assembly in the direction of the flap concerned. Associated plant may use parallel belts (17) on a lift (15) to feed the product to a stand (4) adjacent to a roller conveyor (5) with retractable sections, using ram (24) actuated pivoting plates (22) to carry out first folding.

Title: Membrane for controlling gas valve - opens or shuts valve helped by hydraulic actuator and pressure differential
Inventor: CHARRON JEAN-CLAUDE
IPC: F23N1/08
Filed: 1982-04-20
Abstract: The membrane opens a gas valve in a water heater or boiler. It is controlled by a pressure differential between an intake upstream of a venturi (13) on an inlet pipe and a tapping on the venturi neck. The inlet valve (10) opens and closes when initiated from a primer movement of the membrane (3), due to a hydraulic control which gives a positive or negative pressure change acting on the membrane. The pressure differential is between the chamber (4) above the membrane and that below (5), relative to pressure difference between the upstream pipe (8) and the pipe neck (7).

Title: Corrosion speed measurement method - determining transfer resistance of electrodes in corrosive soln. in 10 to 2000hz range
Inventor: CROLET J-L
IPC: G01N17/02
Filed: 1982-05-27
Abstract: The procedure is based on the measurement of the relation existing between weak perturbations (dv) of the metal-solution potential and the induced variations (di) of the current density circulating between the metal and the solution. The corrosion speed V=K/R where K is a constant and R, the transfer resistance =dv/di. The resistive part of the impedance is measured of the highest frequency for which the reactive part of the impedance passes through a minimum in the range 10-2000Hz. The appts. has a variable frequency voltage generator (1) connected to a potentiostat (3) supplying current to measuring electrodes (5) in the corrosive solution in such a way that they present on electric voltage equal to the delivered voltage supplied by the generator. The potentiostat is then connected via a current current-voltage converter (6) to an adjusting circuit connected to display (8) and comprising a phase comparator (7) and on output conditioner (9). The phase shift between the delivered voltage and the voltage supplied to the current-voltage converter is measured and displayed. The transfer resistance (R) is then measured at the frequency where the phase shift is a minimum and converted to a corrosion speed.

Patent FR-2547106-A1 (FR)
Inventor: HENNEVIN BERNARD
IPC: H03K17/08
Filed: 1983-05-30
Abstract: An equalizer circuit for switches connected in series between a voltage source (21) and a load (16), each switch (4, 11) being connected in parallel with a respective equalizing capacitor (2, 9) via a respective diode (7, 8). The circuit further includes a transformer (20) having a plurality of windings (6, 13) connected in series with respective diodes (5, 12), with each switch having a respective winding-diode series connection connected in parallel therewith. In this manner, electrical energy initially stored in the capacitors is transferred to be stored in magnetic form by the windings when the switches are closed and is re-used when the switches are opened to accelerate charging of the less charged capacitors until all the capacitors reach the voltage of the most charged capacitor. The invention is particularly applicable to semiconductor switches such as transistors or gate turnoff thyristors connected in series and needing protection against exposure to excessive voltages due to differences in switching times between switches.

Title: Water-heating appliance for vehicles with internal combustion engines, especially for a camping car.
IPC: F24J3/00
Filed: 1983-11-07
Abstract: Water-heating appliance composed of a stainless steel tank 13 surrounded by a thermally insulating material 14 and by an external jacket 15, characterised in that water at low temperature coming from the engine water pump equipped with the part 23 enters via the hose 1 and causes the hydraulic turbine 2 to rotate. The turbine can be disengaged from its rotating shaft 3 whose rotation can be locked if necessary by a locking system 4, also disengaging the turbine. On the shaft 3 there is a spring 5 compressing the movable discs 6 and a thermostat 7 which pushes the spring 5 back when the water has reached 92 DEG C. The movable stainless steel discs 6 bear functionally on the stationary discs 8 made from special FEC37 steel. The friction of these two steels has the property of generating considerable heating. All these discs are perforated. The water, passing through the discs via the perforations with which they are provided, recovers the heat produced by the friction and reaches a higher temperature. This water leaves the heating chamber 9 via the orifice 10 and then circulates in the heat exchanger 11 consisting of a copper tube coil of diameter greater than the inlet tube 1. The water contained in the isothermal tank is thus heated.
