Patent EP-0359865-A1 (EP)
Inventor: BITTORF HANNJORG DIPL-PHYS
IPC: H01J35/10
Filed: 1988-09-23
Abstract: The invention relates to an anode plate (7) for a rotary anode X-ray tube, which has a base body (11) of molybdenum on the topside of which a layer (10) of a tungsten-rhenium alloy is laid which carries the target track (6). The proportion of tungsten relative to the cross-sectional area of the layer (10) lying parallel to the target track (6) is reduced with the depth of the layer (10). This can be done when the connection of the anode plate (7) to the layer (10) has a saw-toothed profile, the proportion of rhenium in the tungsten- rhenium alloy of the layer (10) grows with the depth (d) of the layer (10), or there is arranged between the layer (10) with the tungsten- rhenium alloy and the anode plate (7) consisting of molybdenum an intermediate layer (12) which consists of an alloy of molybdenum, tungsten and rhenium. <IMAGE>

Abstract: The movement of an object in an NMR experiment is represented by carrying out a harmonic analysis of the images based on a decomposition of the motion of the object into a Fourier series. A set of images representative of the Fourier components of the motion is then available. These are subsequently recombined as required to produce either an image that is moving as a whole or an image of what is stationary in the object or, lastly, an image of only what is moving. …<IMAGE>…

Title: Method and apparatus for laser processing of materials.
Inventor: SHARP CHARLES M
IPC: H01S3/10
Filed: 1988-07-05
Abstract: An improved method of laser processing of a material by directing a laser beam against the material comprises providing the beam with a power waveform with respect to time characterized by a plurality of peak power pulses and a predetermined CW power level between the peak power pulses such that the average beam power maintained is equal to or greater than the predetermined CW power level of the beam. The method is particularly adapted for cutting material such as aluminum, copper and stainless steel with improved cut quality at a relatively high cutting speed and for welding.

Abstract: Un agencement de câble d'alimentation supplémentaire à trois conducteurs (100) sert à connecter une source d'énergie à courant continu aux borne s d'une batterie devant être rechargée. Le caractère unique de cet agencement consiste en une combinaison de facteurs, y compris :(a) la modification des serre-fils (102, 104, 106, 108,) serrant les extrémités du câble de façon à assurer que les mâchoires opposées de chaque serre-fil restent ouvertes lorsqu'elles ne sont pas en contact avec les bornes positives de la batterie ou de la source d'énergie, (b) la présence de deux conducteurs séparés (432, 442; 433, 443) pour connecter les serre-fils des bornes positives de la batterie à recharger et (c) des circuits de commande particuliers à un agencement de câble d'alimentation supplémentaire à trois conducteurs. En vertu de ces caractéristiques, parmi d'autres, la logique du circuit de commande peut empêcher la formation d'arcs électriques entre les serre-fils des bornes positives au cas où ceux-ci seraient déconnectés par accident lorsque le transfert d'énergie de la source d'énergie à la batterie a déjà commencé. Cet agence ment de câble pour batteries est ainsi particulièrement utile pour charger des batteries situées dans des endroits renfermés, relativement non-aérés (par exemple, le compartiment moteur d'une voiture ou d'un bateau).

Abstract: Le système de communication est fondé sur un dispositif de commutation de paquets (PVE) à commutation par technique de communication à multiplexage temporel ("fast packet switching") auquel sont reliés plusieurs terminaux utilisateurs (TLE). Plusieurs canaux logiques ou virtuels, subdivisés en sens de transmission entrant et sortant, sont acheminés par un raccordement utilisateur. Une partie desdits canaux logiques est configurée en un réseau annulaire virtuel à l'aide d'un dispositif de commande central (ZST) et d'un dispositif de réseau de couplage (KN) lorsque se présente une information de sollicitation. On a prévu à cet effet dans chaque terminal utilisateurs (TLE) une commande d'accès au réseau annulaire (RZS) servant à former le circuit requis avec les canaux logiques concernés dans le terminal utilisateur (TLE). Le réseau annulaire virtuel ainsi formé est exploité et contrôlé à l'aide d'une procédure d'accès annulaire indépendante des procédures de commutation de paquets, par exemple une procédure d'accès par jetons. On peut former soit plusieurs réseaux annulaires dans un seul dispositif de commutation de paquets (PVE), soit un seul réseau annulaire sur plusieurs dispositifs de commutation de paquets (PVE).
