Patent FR-2507855-A1 (FR)
Title: Tension controlling distributor head for an automatic wiring machine - has electromagnets controlling tensioning jaw pivotable w.r.t. fixed jaw, and wire breakage restoring mechanism
IPC: H05K13/06
Filed: 1981-06-11
Abstract: The tensioning wire dispenser mechanism assembled on a rigid block (1) which moves on lateral bearings (12). Wire is fed from a supply reel (5) and guide pulleys (2) to the tensioning arm (13). The wire is dispensed to the connection point on the circuit board (20) through a capillary tube (4). The wire tension is controlled by the movement of two jaws one of which is able to rotate with respect to the other. A variable current supply (15) activates an electromagnet (13) which generates movement of the joins against the action of a return spring. A second electromagnet (14) causes a rotation of a lever (16) which is integral with the frame holding the tensioning electromagnet. When the wire breaks the resulting rotary movement of the tensioning electromagnet causes the breaking of an externally connected circuit (21) through a pair of contacts (6). The electrical signal so generated causes the supply to the second electromagnet to be broken and its armature returns to its normal rest position under the action of its return spring (18).

Title: Roof and wall sandwich panel - formed by casting foam mixture on outer layer and pressing on metal profile
IPC: E04C2/296
Filed: 1981-07-09
Abstract: The outer layer of an isolating panel for building construction, to which pref. a profiled inner plate is attached, have between them a mass of foamed filling material, is to be regarded as the outer, finished, waterproof, non-metallic surface of the roof or wall. Down one long edge an overlapping strip projects and this is glued along the edge of the adjacent panel in the finished structure. The filling along the edge which is to come into contact with an adjacent panel is profiled obliquely to suit. The outer, waterproof layer is a mixture of bitumen and polypropylene with a reinforcement formed by non-woven polyester fibres. The profiled inner layer is a steel plate. The filling is a polyurethane foam and at one side the profiled plate projects beyond it. This facilitates the making of the joint and in particular with a roof, sagging is prevented when it is walked on so that the filling is not easily broken up.

Title: Apparatus for displaying images.
Inventor: ROKUNOHE MITSURU
IPC: G21C17/08
Filed: 1982-10-28
Abstract: The image-display apparatus according to the present invention permits perfect conformity to be obtained between an image formed at the front end F of a bundle 2 of optical fibres and the image appearing at the rear end R of this bundle. In order to obtain this result, the apparatus comprises an address convertor which stores previously obtained information which relates to the relationship between the geometrical addresses of the individual optical fibres at one of the end faces of the optical bundle and those of the optical fibres at the other end face. This address convertor enables the light components of an image transmitted by the bundle to be rearranged according to the geometrical addresses of the fibres at the entrance of the bundle so that an image faithfully reproducing the initial image is obtained on a cathode ray tube 20.

Patent FR-2544756-A1 (FR)
Inventor: LAMORT JEAN-PIERRE
IPC: D21B1/34
Filed: 1983-04-22
Abstract: The invention relates to a primary pulper turbine for processing recycled paper, of the type having the general shape of an helix. This turbine is formed of a shaft (2) carrying at least two helical disks (3, 4) coaxial to the shaft (2) and having a small pitch. These disks extend over at most 360 DEG  and are spaced from each other along the shaft (2) by a distance of at least 1.5 times the helical pitch of a disk. The turbine carries on its base a set of radially extending fins (6, 7, 8), each one of which is curved into a spiral starting from the shaft (2). Preferably, the slant of the helical disks (3, 4, 5) relative to a plane perpendicular to the shaft (2) is approximately 15 DEG , and the disks are angularly spaced from each other by a same angle approximately equal to 360 DEG  divided by the number of disks, for providing a proper dynamic balance of the turbine. The turbine of the invention is designed so as to have a high separation power for fibers, and to separate contaminants, such as plastics, from the paper pulp, without breaking them up into small pieces. This design lends itself to the building of small efficient primary pulpers, the volume of which may be less than 5 m3, as well as of larger ones.
