Patent EP-0135672-A1 (EP)
Inventor: HENNEVIN BERNARD
IPC: H02H7/10
Filed: 1984-05-29
Abstract: An equalizer circuit for switches connected in series between a voltage source (21) and a load (16), each switch (4, 11) being connected in parallel with a respective equalizing capacitor (2, 9) via a respective diode (7, 8). The circuit further includes a transformer (20) having a plurality of windings (6, 13) connected in series with respective diodes (5, 12), with each switch having a respective winding-diode series connection connected in parallel therewith. In this manner, electrical energy initially stored in the capacitors is transferred to be stored in magnetic form by the windings when the switches are closed and is re-used when the switches are opened to accelerate charging of the less charged capacitors until all the capacitors reach the voltage of the most charged capacitor. The invention is particularly applicable to semiconductor switches such as transistors or gate turnoff thyristors connected in series and needing protection against exposure to excessive voltages due to differences in switching times between switches.

Abstract: A stimulable phosphor sheet (3) carrying a radiation image stored therein is scanned by stimulating rays (16) which cause the stimulable phosphor sheet to emit light in proportion to the stored radiation energy, The emitted light is photoelectrically detected (5) to obtain an electric image signal of the radiation image. A signal amount corresponding to after-glows emitted by the stimulable phosphor sheet and photoelectrically detected when the stimulating rays exist outside of the stimulable phosphor sheet after scanning along at least one scan line is conducted is subtracted from an amount of electric image signal photoelectrically detected when the stimulable phosphor sheet is scanned by the stimulating rays, thereby accurately obtaining an image signal representing the radiation image for use in reproduction of a visible image.

Abstract: An optical scanning apparatus includes a polygon scanner with a system for correcting wobble by double reflection from the active facet without bow. Instead of the impinging light source being transverse to the axis of rotation of a rotating polygon, this rotating polygon (12) having facets (22) at a draft angle (D.A.) to the axis of rotation, a collimated light source (10) almost parallel with the axis of rotation impinges upon the facets (22). By two further reflections at stationary mirrors (18, 20), the light is then reimpinged upon the same facet. The relationship between the draft angle (D.A.) and the angle of the incidence (11, 12) of the light beam as it impinges for the first and second times on the facet is such as to substantially eliminate wobble and bow.

Abstract: @ The invention relates to a method and means for detecting leaks through the cladding of a nuclear fuel rod. 
     Disposed at a predetermined location within the fuel rod jacket (40) is a leakage detector mass (50) which is capable of having detectable eddy currents induced therein through the application of an electromagnetic field, and which mass degeneratively reacts with the fuel rod coolant to detectably reduce the eddy-current producing capability of the detector mass. 
     The method of determining the leakage status of the fuel rod cladding comprises applying an electromagnetic field by means of an electric coil (72a) placed adjacent the fuel rod in operative proximity to the detector mass, and sensing the level of the eddy currents induced in the detector mass upon excitation of the coil.

Abstract: Un détecteur de pression différentiel (10) détecte une différence de pression entre une première pression d'entrée (faible) (12) ou "pression de référence" et une seconde pression d'entrée (élevée) (14) et fournit un signal de détection différentielle représentant la différence de pression. La pression de référence est détectée par un détecteur de pression de référence qui produit un signal de référence représentant la pression de référence. Le signal du détecteur différentiel et le signal de référence sont envoyés à un circuit de correction. Le circuit de correction (24), qui est de préférence un ordinateur numérique, ajuste le signal de référence et produit un signal de sortie amélioré en fonction du signal de détecteur différentiel et du signal de référence ajusté.

Abstract: Method of analysing geophones, comprising sending electric currents through the geophones and deriving desired parameters from the output voltages and/or currents. One string of geophones is used as a reference which compensates influences of temperature. A calibration measurement can be carried out on a precision ohmic resistor. Applied on geophones which have a high damping a negative resistance network is coupled in parallel to the geophone terminals. The pulse response test is used to derive sensitivity, damping and resonance frequency, and to calculate the DC resistance. Distortion tests are carried out on the basis of sine wave currents sent through the geophone(s). 
     The invention also includes an apparatus for performing the method. The apparatus is advantageously microprogram-based.

Abstract: Un robot manipulateur possède trois bras extensibles linéairement (52, 56, 60) montés sur un cadre (10) selon une configuration en triangle et portant à leurs extrémités éloignées une interface de connecteur (62) servant à coupler les bras à un outil pour manipuler des pièces devant être positionnées ou pour un autre type de travail. La structure est telle que l'emplacement du connecteur n'est déterminé que par la longueur des bras, alors que son orientation est déterminée principalement en faisant tourner de manière régulée le connecteur par rapport aux bras. Le désaccouplage entre la position et l'orientation réduit au minimum les calculs nécessaires pour positionner un outil avec précision. Dans le mode préféré de réalisation, la rotation est exécutée par des moteurs d'entraînement (32, 36) des bras, situés au niveau des extrémités des bras à proximité du cadre; cela permet de réduire la masse, et par conséquent l'inertie, au niveau de l'extrémité du connecteur, et d'obtenir une accélération intense et un mouvement rapide de la tête du connecteur et de l'outil qui lui est associé. En outre, une suspension à trois points pour les bras leur confère une grande rigidité, permettant au système de déplacer des charges considérables à haute vitesse et avec une bonne précision de positionnement et d'orientation.
