Patent FR-2554287-A1 (FR)
Title: Automatic load switching unit for building
Inventor: STOLL BENOIT
IPC: H02J3/14
Filed: 1984-10-25
Abstract: The mains supply enters the load circuits through a conventional switch with overload or fault trip. Individual  loads, or load groups, are switched by contactors. Each contactor is connected to a selector through which it can be controlled from an external device, e.g. a time clock or some other form of trip. Superimposed on the signals from the control swithces, typically via OR-gates, are selective load shedding overload detectors. Depending upon the ratio of actual supply current and the reference current setting the loads are tripped off in a preselected sequence until the overload conditions is relieved.

Patent FR-2569277-A1 (FR)
Title: Electrical motion-detection device
IPC: G01V1/16
Filed: 1985-04-11
Abstract: The invention relates to a device for detecting with precision the motion of a sensor, in any direction and without the possibility of external magnetic influences. The sensor 20 comprises an annular passage 31 which encloses a ball 33 made of a nonmagnetic conducting material which is free to move in the passage as a function of the motion of the sensor. The passage 31 has a triangular or trapezoidal cross-section, with a cylindrical peripheral wall formed by a large number of conducting surfaces 27 which are separated by insulating surfaces 26. When the ball 33 moves, it opens and closes alternately an electrical circuit passing through the lateral surfaces 32 of the passage and through the peripheral contact surfaces 27. A detector is linked to the sensor in order to detect these changes of state, within a predetermined frequency range, and in order to deliver a corresponding output signal. The device may be used for detecting the presence or absence of motion of a person or a machine, and it may be connected to an alarm device.
Patent FR-2585937-A1 (FR)
Title: Household device for preserving and maturing cheeses
IPC: A01J25/16
Filed: 1985-04-23
Abstract: The present invention relates to a device permitting the preservation and maturing of cheese by recreating a small cellar, formed by a standard commercial clay container, accommodated in a piece of furniture with a bottom, a door and heat insulation. A piece of ice in a tray to be changed daily recreates the atmosphere of a cellar by providing the moisture and the cool air required by virtue of an adjustable shutter for intake of air which diffuses and spreads over the inner clay walls, after having been in contact with the piece of ice, a natural air circulation occurs on the inside and, by virtue of a difference in temperature, air emerges through a cutout in the bottom. A signal indicating complete fusion appears on the closed door, triggered by a counterweight placed on the piece of ice in its tray.

Patent FR-2568321-A1 (FR)
Title: Fluid energy exchange method
Inventor: FORTAGH JOZSEF
IPC: B01J19/00
Filed: 1985-07-29
Abstract: The installation includes two tubular chambers (5.1,5.2) linked together in a parallel configuration by two sets of four valves (4.1-4.4 and 4.5-4.8). The fluids are pumped around the system by low pressure supply pumps (1,2) and a high pressure circulation pump (3). A pulse attenuating pressure vessel (9) is also connected to the system. Two liquids, one of which has a higher potential energy than the other, circulate in the network in order that energy from one may be transferred to the other. Detectors (6.1,6.2) sense the position of the interface between the two fluids, so that the valves which control circulation may be operated accordingly.

Title: Fuel level indicator for motor cycle
IPC: G01F23/16
Filed: 1985-09-12
Abstract: The indicator has a screw cover on a cylindrical housing with two lateral diametrically opposed connection parts (3,4) and holding ribs (5) on their surfaces to enable connection into the tube between the fuel tank and carburettor. Fuel (13) enters the screw cover (2) which is sealed by a spring membrane acting on an axle (7) connected at its lower end to an electrically conducting metal plate (8). The plate is forced upwards by a spring (9) with a force adjustment screw (10) whose press exceeds the fuel press at a certain lower fuel level. This brings the plate into contact with electrical contacts (11,12) so as to illuminate a lamp on the steering assembly showing that more fuel is required.
