Patent FR-2437028-A1 (FR)
Title: MOS integrated constant current source - has two MOSFETs whose source-drain paths are saturated and connected in series
IPC: G05F3/24
Filed: 1979-09-11
Abstract: The source has a first MOSFET. This is operated with a saturated source-drain path owing to a fixed potential applied to its gate and to one of the other electrodes. Its other electrode carries constant current through an output. A second saturated MOSFET (T2) is provided, whose source-drain path is in series with that of the first MOSFET (T1). It is connected to the current source output (Ua), and its slope is steeper than that of the first MOSFET (T1).

Title: Hydrotherapy cubicle with water circulation - has valves and water inlets, filter heater, fan, thermostat and programme circuit
IPC: A61H33/06
Filed: 1979-09-13
Abstract: The hydrotherapy cabin consists of a cubicle with a water-tight base from which a pump takes the water and redistributes it via valves controlled from inside the cubicles. The water can be distributed through holes, a rose, a hose, or fine nozzles. A gas flow forms bubbles in the water. The pump circuit incorporates a filter, and heating system. The air is extracted through a fan. The temperature is controlled by a thermostat. A water-tight door above the floor level forms a bath in which are steps and handles. A switch is linked to a cord. A programmer selects the hot and cold temperatures. The cubicle is made of panels of laminated material.

Patent FR-2451421-A1 (FR)
IPC: E03F5/10
Filed: 1980-01-15
Abstract: The device for regulating the flow rate of waste water mixed with clear rainwater comprises a collector chamber (1) comprising a first orifice (5) called orifice for receiving the mixed water and second and third orifices (6, 9), called orifices for discharging the water which is concentrated into waste water and clear water. Between the first and second orifice, an adjustable device (10) is mounted, which consists of a first conical element (21) having a lateral opening (22) and is extended by a second conical element also comprising a lateral opening (33) consisting of a shutter (34) whose height can be adjusted. A first protuberance (23) and a second protuberance (24) are used to deviate the mixed water entering the device and a baffle plate (25) closes off, in a partial manner, the inside of the first conical element. After floods or storms, the water which contains a lot of waste water, which is denser, flows through the adjusting device (10) via the second orifice, whereas the clear water, which is less dense, is forced into the collector chamber (1) and discharged via the said third orifice.

Patent FR-2476903-A1 (FR)
Title: High voltage circuit breaker generating dielectric gas by pyrolytic ac - uses PTFE slug in moving contact giving rise to pyrolytic decomposition under the heat of the arc and hastening extinction
IPC: H01H33/78
Filed: 1980-02-27
Abstract: The heat generated in the plasma of an electric arc during opening of a circuit breaker is used to create a pyrolytic decomposition of a thermoplastic slug of PTFE which hastens the de-ionisation of the arc and speeds its extinction. The slug is introduced in the end of the hollow tube (2) forming the mobile contact of the sulphur hexafluoride filled circuit breaker. To operate the breaker the sealed enclosure contg. the contacts is moved downwards. As it does so a rack on its side drives a pinion to operate a pump which, by forcing dielectric gas through horizontal passages in the contact which remains connected to the mobile contact, sets up a circulation of the PTFE gaseous pyrolytic decomposition products. An upper connection is provided at the end of the travel to, if necessary, earth the electric circuit.

IPC: G04R20/00
Filed: 1980-04-18
Abstract: The invention relates to a method and a device for time distribution, consisting of a quartz master clock, which is characterized in that this master clock determines the time in absolute value with the change in instantaneous time and, on the other hand, sets the slave clocks by sequential steps, in particular in the case of the stoppage or change of time, and which has a first main counter (6) which enables the change of the instantaneous time, and a second, follow-up counter (12) which controls the slave clocks in a temporally resettable fashion by successive steps, the said follow-up counter (12) being supplied via an electric circuit (13) which serves it, and its displays are continuously controlled with those of the main counter (6) by means of a comparator (15), provided for this purpose, in such a way that the follow-up counter (12) follows the main counter (6).

Title: Water feed valve with push flow control - has rotary sleeve regulation cutting by pass flow for membrane to move washer onto seat
Inventor: DELPLA CLAUDE
IPC: F16K7/17
Filed: 1980-04-24
Abstract: The valve may control a water feed in a domestic bathroom, using separate controls to authorise and regulate flow respectively. The flow enters through the conduit to an outfall through an annular passage, stopped by the axial displacement of the washer onto the seat and vice versa. A sleeve is rotated to vary the axial interval between the washer and seat and regulate the through flow, effecting the rotation of a screw which drives the nut. The push button acts through a bi-stable mechanism to open or close the valve moving a second valve onto the seat to instigate closure. A bypass flow is now blocked off and directed to the rear of a membrane, which deflects to effect the descent of the washer onto seat.
