Patent FR-2285806-A1 (FR)
Title: Electric fencing installation for controlled grazing - has guide wires for horiz. support cable carrying conducting wire (AR090575)
IPC: A01K3/00
Filed: 1975-09-25
Abstract: The installation consists of a rable (1) stretching horizontally between two guide wires which are fastened to stakes. The cable is fastened to the guide wires in such a way that it can slide along them. The cable passes through tubular bodies (9) on which are freely rotating discs (10) of a size which enables them to rest on the ground while the cable remains horizontal. A support (11) is attached to tubular part (9) and bears a spring (12) ending in a rod (13) whose tip has an eye (14) to take a conductor wire (15) which latter slides along the cable (1). The support (11) holds the electric wire (15) forward of tubular body (9). When it is necessary to move the fence, this can be done either by the stockman or by the animals themselves.
Patent FR-2340551-A1 (FR)
Title: Concrete testing method - comprising measuring length and tensile force with time after casting, to examine for stress cracking
Inventor: SERRANO JEAN-JOSEPH
IPC: G01N3/08
Filed: 1976-02-03
Abstract: The cracking of concrete is examined by preparing a concrete test piece each end of which is attached longitudinally to a joining piece, then maintaining constant the length of the test piece by exerting on >=1 of the joining pieces a controllable force in the longitudinal direction and measuring the intensity of that force. Alternatively variations of length of the test piece are measured. Cracking due to shrinkage of the material can be observed since the length is kept constant.

The vessel has a hole at the top for exit of the flue gases. The outside of the tube is fitted with a spiral fin which increases the effective surface area qf the chamber and assists in the heat exchange required. The burner allows a higher combustion temperature for the gases and increases the combustion efficiency.
Patent FR-2361537-A1 (FR)
Title: Rotary IC engine - has two parallel rotors, revolving in opposite directions, with recesses forming working chamber
IPC: F01C1/20
Filed: 1976-08-11
Abstract: The engine has two cylindrical rotors (A, B) revolving in opposite directions to each other, and each rotor has a rectangular recess cut out of it. The rotors are in contact with each other and the recesses form a large chamber as they come together. The casing has a passage (1) for a sparking plug between the rotors. There is a port (2, 4) and one side of each rotor for admission of fuel air mixture and an extract port (3, 5) on the other side of each rotor. Each rotor compresses a charge and brings it towards the centre where it meets the charge from the other rotor. Ignition takes place when the rotor recesses are together and causes the rotors to revolve in opposite directions.
Patent FR-2323813-A1 (FR)
Title: Prismatically ribbed forgery:proof film for coating documents - has transparent prism section preventing copying by vertical projection processes
IPC: G07D7/00
Filed: 1976-09-13
Abstract: The prismatically ribbed film is used as a protective coating on documents and papers to prevent copying. The prismatic ribs may be equal-sided or irregular, or extend at an angle to the document to be protected. The same effect of preventing copying may be obtained also by a louvred film in which the louvres extend at an angle of 60 deg. to the surface of the document. The direction of the prism pattern or louvre pattern at an angle to the lines of writing increases the effect or prevention of copying, as increased interference of picture information is caused by refraction and misalignment. In an example, a soft transparent film 0.1-0.5 mm. thick is adhered in several layers with an opaquely coloured adhesion e.g. epoxy resin. It is then cut at the desired angle e.g. 60 deg to the plane of the film into thin pieces and, where required, smoothed down and polished.

Title: Loose sheet binding system in cover - uses material with low melting point heated by element outside cover with absorbent pad
IPC: B42C9/00
Filed: 1976-09-23
Abstract: The system binds a packet of loose sheets in a cover, the dimensions of whose back are roughly the same as that of the cross-section of the packet. A plate (3) of solid binder material with a low melting point is placed between the inside of the back and the adjacent side of the packet of sheets. The assembly so formed is held with the external face of the back pressing against a heater element so as to melt the binder material, and any of the binder running out at the ends of the back is absorbed. A heating table can be used, covered by an absorbent component (10) movable in relation to it and removable. There are two or more plates perpendicular to the table and adjustable distance apart, holding the assembly upright so that it rests on the table.

Title: Expandable plug for fixing objects to walls - has resilient claws opened by insertion of screw to improve grip in hole
IPC: F16B13/12
Filed: 1977-02-24
Abstract: An expandable plug which receives a screw in order to fix objects to walls, floors etc. is made from a plastic tube (10). The bore of the tube is stepped from the relatively large diameter (2) at one end to a small diameter at the other. The end with the small bore is provided with a longitudinal zig-zag split (12) and a number of reinforcing rings (7). In the region of transition between the large bore and small bore, two diametrically opposite claws (20) are provided. The claws are deflected elastically into recesses (39) when the plug is forced into the fixing hole, but at the same time the claws bite into the wall of the hole and resist rotation when the screw is inserted.

Title: Air filter for pneumatic transport installations - with single fan drawing transporting air and delivering countercurrent cleaning air (DK 21.11.77)
IPC: B65G53/60
Filed: 1977-03-15
Abstract: An air filter with counter-current cleaning, partic. for air from pneumatic transport installation contains an annular filter cartridge. Air passes through radially from outside to inside during transporting. A pure air space inside the filter connects with a pure air discharge opening and contains an injection pipe, mounted coaxially, and able to rotate. The injection pipe is connected above by a feed pipe to a fan, and it has holes by which counter-current cleaning air can be directed against the filter cartridge from inside. According to the invention, the same fan can be used for transport and cleaning. The rotation of the fan can be reversed so as to change from suction to discharge. The pure air discharge orifice opening into the feed duct is fitted with a valve, open during the operation of the filter under the effect of the depression produced by the fan. One fan can be used for pneumatic transport and for countercurrent cleaning of the filter. System is simpler and less costly to construct than existing air filters. Used for pneumatic transport appts. for automatic feeding of hoppers bringing materials to extruders, or similar machines.

Title: Low loss integral line coupling to semiconductors - uses thyristors integrated into substrate to form matrix of connection points
Inventor: BLACHERE JEAN-MARIE
IPC: H01L21/761
Filed: 1977-06-02
