Title: Chip board producing appts - giving boards of different wall thickness but uniform density
IPC: B27N5/00
Filed: 1969-02-24
Abstract: Appts. comprises an upper plunger adapted to move up and down with respect to an intermediate plunger, a vertically movable support resiliently connected to the intermediate plunger by springs, narrow plungers secured to the movable support and slidably extending along the sides of the intermediate plunger, and laterally movable side plungers adapted to move within recesses formed in the side walls of a metering frame encircling the intermediate plunger, and power clinders for forcefully moving the side plungers inward of the metering frame. When chips are filled in the cavity defined by the intermediate plunger, the side plungers and the metering frame, the upper plunger is lowered and seated against the top of the metering frame and then the side plungers are advanced inwardly to compress the material packed in the cavity portions defined between the sides of the intermediate plunger and the adjacent side plungers. Then the movable support is raised, forcing the narrow plungers and the intermediate plunger upwardly so as to compress the material chips into a compacted board.

Patent FR-2039230-A1 (FR)
Title: Nuclear fuel elements in cartridge form
IPC: G21C21/04
Filed: 1969-12-30
Abstract: The cartridge is filled with particles of nuclear fuel, at least partially mixed into a consolidating or binding paste.

Title: Magnetic tape loop measures moving cable lengths - also non-flexible plates and is driven by pulleys carrying cable
IPC: G01B7/04
Filed: 1973-06-21
Abstract: The length of a moving cable, non-flexible plate etc. passing a given point is measured by transmitting the movement via two pulleys 2, 2' to a belt passing round them and then in the inverse sense round two more 4, 4' which have on the same axles other pulleys driving an endless loop of magnetic tape.

Title: Circuit-breaker reset mechanism - has spring-loaded push-rods controlled by motor driven cam
IPC: H01H71/70
Filed: 1974-02-14
Abstract: This resetting mechanism is mounted on front of a circuit-breaker (D). It is so positioned that when the operate-button of the breaker springs out after circuit rupture, it operates two contacts (13, 14) on the end of an inline pair of push-rods that are interconnected by a spring (7) and mounted in a tube. This causes a battery driven motor to rotate a snail-cam. This is mounted at the end of the tube and its snail profile pushes the rod forwards and depresses the operate-button of the circuit-breaker. The snail profile also allows the push-rods to snap back after the brakes is reset and an auxiliary contact (15) resets the cam to the standby condition.

Title: Production of holograms esp. of superimposed type - reference beam is set between angles of object beams
IPC: G03H1/26
Filed: 1974-10-28
Abstract: An improved quality hologram is obtained by using two or more object beams, each passing through information elements to coincide on the photosensitive surface. The reference beam, of coherent light, is set at an angle evenly between the object beams for maximum effect. The photo-sensitive surface is relief sculptured by the light and a simple arrangement uses photo-sensitive resist material or any similar system. A number of object information elements can be stored in the same place on the light sensitive element without effecting the quality of the pictures. The arrangement can therefore be used for colour video information or for series of pictures with one, two, or three dimensional change.
