Abstract: Le procédé décrit sert à égaliser les contrastes de photographies prises aux rayons X avec un appareil de radiographie à diaphragme à fente. Un dispositif d'absorption commandable (8) agit en interaction avec le diaphragme à fente (2) de façon à influer sur un faisceau de rayons X en éventail (3) par secteur. Le dispositif d'absorption (8) est commandé (10) en tant que fonction de la quantité de rayonnement instantanément transmise (11) par secteur à travers un corps (7), de sorte que la quantité de rayonnement transmise dans un secteur particulier à travers le dispositif d'absorption diminue au fur et à mesure qu'augmente, à partir d'une première valeur seuil en direction du haut une valeur correspondant à la transmission du corps se produisant instantanément dans ledit secteur. Au-dessus de la valeur seuil, une valeur de transmission supérieure a pour conséquence de produire dans une mesure prédéterminée une quantité essentiellement supérieure de rayonnement transmis à travers le corps, au moins dans les régions d'importance pour la photographie aux rayons X.

Date Jan. 26, 1989.A power supply circuit for an electric discharge lamp driven by an A.C. power supply has a regulating transformer connected in parallel with a current limiting reactor and an electric discharge lamp interconnected in series. The tap of the regulating transformer is connected by a condenser and an auxiliary reactance interconnected in series to the connection between the current limiting reactor and the electric discharge lamp. By adjusting the tap of the regulating transformer the performance of the lamp can be influenced within a wide range. In place of the regulating transformer an electronic phase shifter may also be used, which is particularly advantageous when regulating speeds are required that cannot be achieved by means of an electromechanically adjustable regulating transformer.

Abstract: In an end stage circuit arrangement for controlling electromagnetic actuators, a part of the switch-off energy, which is induced in the exciter winding (1) of the electromagnetic actuator by the switch-off operations carried out during operation, is picked up via a decoupler diode (19), in order to generate an auxiliary voltage (-UH or +UH) in cooperation with an auxiliary voltage open-loop or closed-loop control circuit (25). The auxiliary voltage open-loop or closed-loop control circuit (25) controls a switch element (15) which is switched in such a way that the switch-off energy for generating the auxiliary voltage is only used until a desired voltage value is reached. When this voltage value is exceeded, the switch element (15) acts like a free-wheeling diode connected to the exciter winding (1) for reducing induction voltages. <IMAGE>

Abstract: The invention relates to an emergency actuation device for a vehicle door actuated by means of a non-self-locking electrical drive (1, 2, 3, 4). In such doors, the connection between the door drive and the door mechanism (5, 6) is made self-locking at least in the final closing region of the door. According to the invention, to make emergency actuation easier, there is provision for ensuring that, as is known per se, there is arranged in the region of the final closing position of the door mechanism a slide (12) which acts on the door drive (11) in the direction of its opening movement and the displacement travel of which is greater than the self-locking region of the door mechanism.

Abstract: Le procédé décrit, qui permet d'obtenir un article en acier cémenté, consiste à effectuer la cémentation d'un matériau à base d'acier ne contenant pas plus de 0,10% de silicium et contenant moins de 1,1% de chrome, de façon à former une matrice de surface austénitique dans laquelle est dispersée une densité élevée de carbures. Après trempe, l'article en acier cémenté se caractérise par une surface extérieure ayant une proportion élevée de carbures et exempte d'oxydes inter-granulaires. Ceci a pour effet d'empêcher toute formation d'oxydes de surface non désirables et em même temps de former une structure de carbures de surface avantageuse; une telle invention permet d'améliorer considérablement la résistance à la rupture par pliage, les propriétés de résistance à l'usure et de résistance à la rupture par contact d'articles tels qu'engrenages, arbres de transmission, paliers et accouplements.
