Abstract: An integrated and small relief valve both for regulating fluid pressure and removing gaseous contaminants from a fluid. A fluid to be regulated in pressure and to be cleaned is introduced tangentially into a vortex flow chamber (1). A fluid stripped of gaseous contaminants passes through small pores (6) in the wall (4,5) of the vortex flow chamber (1) and is collected in a fluid collecting chamber (11) outside the vortex flow chamber (1) and then flows out through an outlet pipe (12) from the collecting chamber (11). The gas-rich fluid collected near the center of the vortex flow chamber (1) flows into a relief valve pipe (8) extending into the chamber (1) at its axial center, then passes through a relief valve (9) and is removed from the fluid system.

Les positions des impulsions (P1 et P2) permettent de calculer les positions des angles. Deux détecteurs et/ou deux sources de lumière peuvent être utilisés pour augmenter la quantité de données disponibles de sorte à obtenir une solution d'ensemble pour déterminer les coordonnées des centres de courbure (C1, C2) des angles par rapport aux détecteurs et des rayons de courbure des angles.

vorzugsweise Tionylchlorid eingesetzt wird. Dieser Elektrolyt ist in einem geschlossenem Behälter gelagert und wird 
erst 
bei der Inbetriebnahme zerstört, um die Kathode zu benetzen. Den darauffolgenden Anstieg der Sollspannung 
bezeichnet 
man als Aktivierungszeit. Zur Verringerung der Aktivierungszeit und zur Erhöhung der Sollspannung wird dem Elektro­
lyt-Grundbestandteil ein Oxidationsmittel, vorzugsweise in Form von Sulfurylchlorid, zugesetzt.  
     Abstract 
     An electrochemical cell comprises a light-metal anode, a porous metallic or graphite cathode, and a liquid 
electro­
lyte in the form of a non-aqueous inorganic solvent, preferably thionyl chloride. The electrolyte is stored in a 
sealed con­
tainer and is only destroyed when the cell is first used, in order to wet the cathode. The resultant increase in the 
rated vol­
tage is an index of the activation time. In order to reduce the activation time and to increase the rated voltage, an 
oxidizing 
agent, preferably sulphuryl chloride, is added to the basic constituent of the electrolyte.

Abstract: Dans les procédés d'électrophotographie en couleurs habituels utilisant un seul système de transfert, on utilise un toner de couleur ne produisant la densité d'image la plus élevée qu'après superposition d'une quantité de couches pouvant aller jusqu'à six. Par conséquent, la tonalité chromatique d'une image en couleurs mélangées formée par la superposition d'images de toner de différentes couleurs est susceptible de se modifier, ou il est possible que des non-uniformités de couleurs se produisent. La présente invention utilise uniquement un toner de couleur dont une seule couche permet d'obtenir essentiellement la densité d'image la plus élevée, afin d'éliminer les désavantages susmentionnés et de permettre de reproduire une image en couleurs mélangées en utilisant un système de transfert unique. Grâce à la présente invention, on peut reproduire fidèlement une image panchromatique présentant des dégradés de couleurs.

Abstract: The invention relates to a device and a method for optimising the brightness and the contrast of a video image, which is used for controlling a manipulating device (2). The gain/offset control of the video camera (1) is determined by the picture control unit (3) in such a manner that the weighted mean value (13) of the object brightness (11) assumes a fixed predetermined value (10). Furthermore, the gain parameter of the video camera (1) is optimised with respect to the contrast (15) between the weighted brightness (13) of the object (7) and the corresponding value (14) of the background (8). The determining factor in this is the minimum overlap of the brightness distributions (11,12) of object and background with minimum contrast (15) of the weighted mean brightness values. The manipulating device (2) can be an industrial robot (21) by means of which a workpiece (71) or tool (72) can be treated. As a further possibility, the manipulating device (2) can be used in the form of a platform (22) for tracking a target (73).
