Patent EP-0440317-A1 (EP)
Inventor: GRAFF ALFRED DIPL-PHYS
IPC: G01N29/04
Filed: 1991-01-22
Abstract: The invention relates to a method and test apparatus incorporating a magnet system for testing ferromagnetic workpieces by ultrasonic waves, in which an alternating magnetic field (B &tilde& ) aligned parallel to the surface in the test body is produced by means of a magnet system (10, 11) applied to the surface (15) of a ferromagnetic workpiece and excited with alternating current and high-frequency transmission pulses are triggered in the region of the maximum amplitude of the magnetic field strength by a transducer coil (14) mounted in the vicinity of the surface of the workpiece. In order to test ferromagnetic workpieces for faults on the one hand at various predetermined angles and, on the other hand, as an alternative, to be able also to determine the thickness of the workpiece in addition, the invention proposes that a magnetic field (B  ORTHOGONAL ) of quasi-static polarity aligned vertically with respect to the surface of the workpiece and produced with the magnet system (13) is generated and superimposed in the alternating magnetic field and that, regardless of a desired acoustic radiation direction, high-frequency transmission pulses are triggered either only in the region of the upper half wave or only in the region of the lower half wave of the alternating current. <IMAGE>

Abstract: An isolator mechanism (10) is provided for use with a machinery housing (12) and a rotatable shaft (13) protruding through the housing (12). The isolator mechanism (10) comprises a stator ring (20) affixed to the housing (12) and a rotor ring (22) which is attached to the shaft (13) and which nests within the stator (20). The stator (20) and rotor (22) are so shaped that the stator (20) has a male cylindrical surface (56), and the rotor has a female cylindrical surface (54) located radially outwardly of the stator male surface (56). A solid, deformable annular seal member (60) is mounted on the rotor female surface (54) and engages the stator male surface (56) when the rotor (22) and seal member (60) are at rest. However, the deformable seal member (60) is deformed by centrifugal motion into a configuration out of engagement with the stator (56) when the rotor (22) and seal member (60) are moving at operating speeds.

Inventor: ALLISON JAMES HENRY
IPC: A62C35/62
Filed: 1991-01-08
Abstract: An apparatus and system for storing and supplying liquid CO2 at low pressure for extinguishing fires. The apparatus comprises a pressure vessel (13) for storing liquid CO2 at low pressure, a cooling means (29) in contact with gaseous CO2 in the vessel to maintain the low pressure, an inlet (24) and outlet (32) to fill the vessel and a supply conduit (17) communicating with a lower portion of the interior of the vessel to allow liquid CO2 to pass from the vessel and into a reticulation system. A number of pressure vessels can be coupled together through a manifold (165) to provide the required amount of liquid CO2 to a risk site. Supply valves (18) or manifold valves (173, 174) can be operated by a sensor (175, 176) in a risk site and a logic processor (177) can be used to regulate the valves and thereby the liquid CO2. The apparatus and system is particularly designed as a replacement for current halon systems which cause damage to the ozone layer.

Abstract: Système de commande de conversion de coordonnées tridimensionnelles dans une unité de commande numérique servant à la commande d'une machine-outil comportant plusieurs têtes. Un organe de calcul de prétraitement (2) décode un programme d'usinage (1) et exécute la conversion des coordonnées uniquement pour une première tête à l'aide de trois organes de conversion de coordonnées tridimensiionnelles (3), et un organe de distribution d'impulsions (4) distribue les impulsions de cette valeur de coordonnées. La valeur de coordonnées pour la première tête est utilisée en tant que telle pour une deuxième tête et l'organe de distribution d'impulsions (5) distribue les impulsions. On parvient de la sorte à réduire le nombre de calculs lors de la conversion de coordonnées tridimensionnelles, ainsi que la charge de traitement de l'unité de commande numérique.

Abstract: L'invention se rapporte à un dispositif à circuits intégrés à semi-conducteurs, tel qu'une puce de mémoire, dans lequel le nombre des câblages est augmenté, ce qui entraîne un accroissement de la capacité de la mémoire. Le problème qui est créé lorsqu'on désire améliorer la fiabilité et la vitesse d'accès d'une ligne de bus commune, sur laquelle ces câblages sont placés, concerne les trous de passage ménagés dans les câblages d'une seconde couche et les parties de connexion utilisées dans la partie où les câblages de transmission des signaux et les câblages d'alimentation de la région rétrécie de la ligne de bus commune interfèrent les uns avec les autres. C'est pourquoi, dans la présente invention, les câblages de l'alimentation principale qui se branchent sur la ligne de bus commune sont placés le long et à proximité des circuits processeurs des câblages de transmission des signaux disposés sur la ligne de bus commune. Ainsi, on peut obtenir des câblages dans la seconde couche qui sont de largeur étendue et on peut placer la pluralité des trous de passage en chaque point de connexion, un circuit intégré à semi-conducteurs ayant une fiabilité et une vitesse d'accès élevées étant alors réalisé.

Abstract: Dans ce procédé et cet appareil, on détecte le mouvement en captant les variations de la luminance, sur une période de temps, entre des images séquentielles au niveau de chaque site de pixel d'image et les variations de la luminance au niveau de sites de pixels voisins. On utilise ensuite ces variations pour calculer le déplacement de l'image toute entière ainsi qu'un degré de variation de l'image indépendant de la direction. Le déplacement total étant calculé et représenté par des signaux, on peut ensuite utiliser ces signaux pour commander en temps réel, la vitesse de l'obturateur de la caméra, l'ouverture du diaphragme, et/ou le mouvement du film dans une direction qui suit le déplacement afin de réduire au minimum le flou sur l'image enregistrée. Ces mêmes signaux peuvent être mis en mémoire pour une utilisation ultérieure, par exemple dans une opération de restauration.

Des miroirs à plusieurs facettes ou incurvés peuvent être utilisés pour augmenter le rayon de l'azimuth. Un traitement graphique est utilisé pour présenter des images d'observation normales et/ou le résultat de comparaisons d'images.

Abstract: The invention relates to an arrangement for fixing the winding overhangs (13) of armature coils by means of end discs (15) which are arranged at the ends on a laminate stack (5) and consist of insulating material. This end disc (15) has a cylindrical attachment (23) which is provided with a cylindrical recess (25) for holding a part of a bearing (27) for an armature shaft (3). According to the invention, a U-shaped circumferential groove (37) is now provided, between a disc part (35) having the radial webs (19) of the end disc (15) and the cylindrical attachment (23), for holding armature windings, in such a manner that the winding turns run like chords over the end surface (39) of the disc part (35) of the end disc (15). In consequence, the structural volume of the winding overhangs is reduced in the radial and axial directions. In addition, a more compact construction of the armature is made possible, copper also being saved to a considerable extent. The construction of a powerful motor with a short structural length is thus possible in a simple manner. <IMAGE>
