Patent FR-2234136-A1 (FR)
Title: Cylindrical silk screen making method - prepared outside the press to gain press adjustment time
IPC: B41F15/38
Filed: 1974-06-10
Abstract: When being prepared, the tube like screen is fitted on both ends with an inside ring. These rings have bayonet-slots along their inner diameter. When being prepared a tensioning device is fitted in the slot to give the screen a firm position and prefixed tension. The same provision exists on the acceptance position of the machine. When transferred the preparation tensioner is released but the end rings stay on. They will then be accepted in the machine in the same bayonet slot and tension. This means that the image will not be distorted due to torsion of screen, while being transferred from proofing press. to actual printing press.

Title: Rock crusher with annular metal cutter - has coaxial shaft mounted in elastomeric bushing of housing
IPC: B28D1/26
Filed: 1974-06-25
Abstract: Rock crusher has a roller cutter with an annular metal cutter with a tensile strength to resist impacts without permanent deformation, and a long shaft coaxial with the cutter and extending through it. The shaft is mounted in a housing which has an easily deformable elastomeric bushing whose outer periphery engages at least an inner periphery of the cutter and which extends radially inward from it. The bushing has a stiffness to deform in reaction to an impact force on the cutter such that the energy transfer to the housing is minimal, and a limited cross motion of the cutter w.r.t. the shaft's long axis is possible. The cutter can be rolled over the rock surface to break off pieces in continuous cuts; only a small fraction of the forces driving the cutting edges into the rock is transferred to the cutter tool mounting.

Title: Protection circuit for printed circuit boards - uses thyristor to short circuit supply when comparator detects discontinuity in circuit
Inventor: BONAMI ROBERT RAOUL CHARLES
IPC: H02H9/00
Filed: 1976-05-24
Abstract: The protection circuit protects printed circuit boards when they are being plugged into or withdrawn from their connectors by detecting a break in a loop formed by all boards and then short circuiting their supply. Special conducting paths (a1) join the end contacts of each board (c1) together so that suitable wiring (L) between the connectors (B1) allows all board's special paths to be connected in series (loop) between earth and a comparator's (D) input. When the loop is broken by removing a board the comparator turns on a thyristor (T) that short circuits the supply (S) to the boards. The special conducting paths are connected to short contacts on the boards so that the supply is short circuited before the other board contacts break contact.

Title: Solar furnace using nonfossil combustibles - operates by chlorine ionising and hydrogen in reaction chamber and combining the ions in combustion chamber
IPC: F24S20/20
Filed: 1976-06-18
Abstract: A solar combustion furnace incorporates a solar reaction chamber, controlled inlets for chlorine and hydrogen, appts. for introducing electro-magnetic radiation, partic. solar radiation, into the chamber to ionise the Cl2 and H2, and a combustion chamber. A valve allows controlled entry of oxygen into the combustion chamber. The ionised cl2 and H2 pass through a valve into the combustion chamber and react exothermally producing HCl at high temp. and press. The furnace incorporates components to concentrate the radiation, direct it into the reaction chamber and disperse it over the whole chamber. The energy produced in the reaction may be used to generate steam or to drive a turbine or a piston engine. The combustion products can be put into a circuit so as to maintain permanently the exothermic reaction.

Title: Position of traction cable checking system - uses probe signalling when cable derailment on balancing pulley assembly occurs
Inventor: CHAVE JACQUES GEORGES
IPC: B61B12/06
Filed: 1977-05-18
Abstract: The position of a cable used in a lifting or similar machine is checked w.r.t. a guide pulley to ensure that the cable is correctly positioned. A probe operated by pulley movement signals derailment of cable. A cable (1) is guided by pulleys (102) and guide plates (106) fixed to pulley mounting (103) prevent derailment. A central hole (104) enables the pulleys to act as balancing assembly. One pulley (102) is mounted on cylindrical support with radial collar (5) to enable sliding w.r.t. the other pulley (102'). A shaft (7) contacts a blade spring (9) operating against pins (16) to keep pulley in contact with cable. A detector (20) signals when no load is applied to pulley thus signalling a derailment.
