Patent FR-2572062-A1 (FR)
Title: Automatic depiler (or feeder or loader) for a printing press, varnishing machine or press for converting (fashioning) the sheeted material, with automatic pile changer
IPC: B65H1/30
Filed: 1984-10-18
Abstract: The invention relates to an automatic depiler fitted with a system for automatically replacing the piles. It consists of a frame A supporting the usual members for separating, lifting and transporting the sheets and including, in order to support the pile, two superposed platforms B and 1 which can be raised or lowered each by its own system of motors H and 8, reduction gears, wheels and chains C and 3. When the pile is supported by the upper platform 1, it rests on a retractable grid or fork 2 under the action of actuators 20 in order to permit the loading of a new pile onto this platform by passing across the latter. The actuators then push back the fork 2 under the pile. The fork 2 is hollow and supplied with pressurised air in order to blow air cushions which lubricate its movement and protect the sheets. The pile changing is performed in an automatic sequence of phases which is controlled by a central unit. This depiler is intended for the printing and metallic packaging industries.

Title: Electromagnetic linear travel device
Inventor: SAVARY FERNAND
IPC: G21C7/14
Filed: 1985-01-29
Abstract: The device is designed to move a drive shaft capable of being attached to a nuclear reactor control rod. It comprises a first and a second set of means for gripping the drive shaft which are offset in the lengthwise direction. The first set of means is associated with a movable pole interacting with a supporting coil 18 carried by the enclosure and capable of being moved by excitation and switching off of the coil between a position where the first set of means grips the drive shaft and a position where it releases it. The second set of means comprises a movable plunger 46 interacting with a transfer coil 16 capable of being moved, by excitation and switching off of this coil, between a position of bearing on another pole 36 where the set of means grips the drive shaft and a position where it releases it. This other pole interacts with a lift coil 14 enabling it to be moved between two positions separated by a specified gap. The movable pole 28 and the stationary pole 22 of the second set of means are of such form that the law of variation of the lifting force as a function of the travel exhibits a small average increase.

Abstract: Amortisseur de vibrations à deux tubes 1, 2, dans lequel le piston 7 agit sur un ressort de butée 16 lorsqu'il parvient en une position prédéterminée au cours de sa course de rentrée. Le ressort de butée 16 agit sur un organe de commande 17. Ce dernier coopère avec un passage inférieur pour réduire la section de passage de celui-ci lorsque le piston 7 commence à agir sur le ressort 16. On obtient ainsi un effet de butée hydraulique à la rentrée de la tige de piston 6. L'organe de commande 17 est soumis à l'action d'un ressort de rappel. Le ressort de butée 16 agit par son extrémité opposée à l'organe de commande 17 sur une bague de friction 15, glissant contre la surface interne du cylindre 1. La tension du ressort de rappel est supérieure à la force nécessaire pour déplacer la bague de friction 15 le long de la face interne du cylindre 1. (CF DESSIN DANS BOPI)

Title: Method for determining the inertia of a motor vehicle and automatic regulation of the engine unit
Inventor: DRUTEL YVES
IPC: G01M1/10
Filed: 1986-10-24
Abstract: Method for automatic regulation of an engine unit of a motor vehicle, in particular by acting on the injection rate of the fuel, by a computer 1 controlling, in particular, changes of transmission gearing of the vehicle transmission, characterised in that an initial estimated value of the inertia of the vehicle is stored in the computer 1, then a determination of the inertia is carried out by making two different measurements of the acceleration of the vehicle for two separate transmission gearings, and finally in that the value of the inertia used in the regulation is updated by the value thus determined, when the regulation is in a stable running phase, the regulation coefficients then being self-adapted as a function of this updated value of the inertia. The central computer 1 receives information from the driver 2 and supplies data to the computer of the engine 3, to the computer of the transmission 4 and to the computer of the injection device 5, these computers furthermore returning to the central computer 1 information on the state of the various sensors.

Abstract: This device uses a wave inverter of the "with current" type which comprises an oscillator 10 intended to emit a pulse train proportional to a signal of frequency of operation of the wave inverter; a phase signals generator intended to receive the pulse train emitted by the oscillator 10 and to produce a phase signal in response to a DC excitation signal engendered by a dynamic braking signal; and a gate signals generator 12 intended to produce gate signals U, V, W, X, Y, Z in response to the phase signal, these signals being applied to the said wave inverter in such a way that the operation of switching the branches of the wave inverter can be executed. The control device furthermore includes a phase data generator 13 intended to store and emit a phase datum signal just prior to a first operation for switching branches so that, when the DC excitation signal is present, the phase signals generator is set into action in order to emit in the same state the phase datum signal stored in the phase data generator 13, whereas, when the DC excitation signal is cut, the phase signals generator is set into action in order to count the pulse train additional to the phase data signal stored, in order thereby to emit the phase signal in the form of ramps.
