Patent FR-2332412-A1 (FR)
Title: Locking stator to rotor of underground motor - for release of wedged tools, esp. in deep holes
Inventor: DICKY LEONIDE
IPC: E21B17/04
Filed: 1975-11-19
Abstract: In a subterranean motor for drilling deep holes, the rotor can be locked to the stator. The stator has attached to it a fitting enclosing a sliding sleeve which turns when the fitting turns. The sleeve is normally held by a peg in a first axial, upper position, in which it has no effect upon the normal functioning of the motor. Through the sleeve is an axial passage for the drilling fluid with an inlet such as can be closed if a ball is dropped into it. As pumping is continued, the pressure on the fluid builds up until the retaining peg is sheared, and the sleeve is released into a second position where it engages with a nipple fixed the shaft of the rotor, so that stator and rotor are locked in rotation. When the boring bit secured to the lower end of a subterranean motor becomes wedged in the hole, the stator can be locked to the rotor and torque then applied from the surface to release the tool.

Title: Rotary cutter boring head lubricated in closed circuit - has cutter driven pump and lubricant reservoir balancing pressures
IPC: E21B10/24
Filed: 1975-12-24
Abstract: Boring head with rotary cutters, for attachment to a train of boring bars or to the transmission of a high speed turbo drilling motor, has arms, each extended by a downwards inclined trunnion for a rotary inserted tooth cutter. The rotary cutter is supported by an arrangement of bearings guiding its rotation whilst stops prevent any axial motion. The bearing and thrust surfaces are protected against the abrasive environment by seals and are lubricated from a reservoir in a closed circuit. The lubricant is returned from the bearing and thrust surfaces to the reservoir, and a pump is set up between the rotating cutter and the trunnion. The pump is formed by spiral grooves in the bore of the cutter and pref. these are machined in a bush pressed into the bore. The pumped is thus driven by the motion of the cutter and the circulation of the lubricant is ensured. The lubricating system works so that breakdown of the lubricant is prevented, and lubrication generally is improved. The cutter bearings are cooled so that the tool can work at very high speeds and with long life.

The measuring device can be regulated either when the centrifuge is stopped or during operation. On centrifuges that required periodic cleaning of the bowl due to clogging by the materials separated. Device can be adjusted during operation of the centrifuge according to the different densities of liqs. and solids to be separated.
Patent FR-2343345-A1 (FR)
Title: Quick action coupling for electrical connectors - has spring biased ball bearings in bayonet fitting which can be decoupled by axial pull on cable
IPC: H01R13/625
Filed: 1976-02-18
Abstract: Coupling or interlock mechanism is for electrical plugs and sockets esp. cylindrical types. Coupling and disconnection of the two mating elements can be accomplished rapidly in positions providing minimum access. Insertion is accomplished by a simple axial movement followed by a short rotational turn of the free element. Disconnection is achieved by a simple axial pull, wh ich can be done remotely by pulling on the cable itself. Interlocking of the free and fixed connector parts is by several ball-bearings moving into bayonet like sockets against spring pressure. This same pressure allows a direct pull to twist the free element and release it.

Title: Tube-image couleurs, procede pour fabriquer un tel tube-image couleurs pourvu d'un masque perfore et masque de reproduction utilise dans un tel procede
IPC: H01J9/14
Filed: 1977-08-04
Abstract: En élargissant d'au moins 20 % les petits ponts dans quelques rangées d'ouvertures situées au bord du masque perforé d'un tube-image couleurs, on diminue les risques de déchirure pendant l'étirage en forme. En maintenant, en outre, la largeur des petits ponts constante par rangée et en permettant à cette largeur d'augmenter, de préférence à peu près d'une manière linéaire, régulièrement d'une rangée à l'autre à partir d'une rangée passant par le centre du masque perforé jusqu'à une rangée située au bord de ce masque, on obtient également une répartition de luminosité sans discontinuité. Le masque de reproduction utilisé pour fabriquer un tel masque perforé peut être obtenu d'une manière simple en faisant tourner le motif de petits ponts entre deux expositions nécessaires pour le tirage sur un matériel photosensible et en combinant le tirage ainsi obtenu avec un motif de bandes. Application à la télévision en couleurs.
