Abstract: 1. A process for leak testing electric components (13) which have an inner hollow space (15) in a sealed housing (14), wherein the component (13) to be tested is inserted into a recipient (16) connected to a cylinder (18), and a change of pressure is brought about in the recipient (16) by displacing a piston (19) in the cylinder (18), wherein after a predetermined time interval the pressure in the recipient (16) is measured by comparison with a predetermined theoretical value, and a deviation of the measured pressure from the theoretical value or the observation of the theoretical value, as the case may be, is indicated, characterised in that during the insertion of the component (13) into the recipient (16) the piston (19) is retained in a defined rest position (A) within the cylinder (18), that when the recipient (16) has been closed the piston (19) is displaced into an operating position (B, C) and that after the predetermined time interval the pressure in the recipient (16) is measured by a pneumatic-electric transducer (21).

Abstract: A numerically controlled machining system, which enables rough machining using command data for finishing. A clamping means clamps a pre-designated driving shaft onto clamp-coordinates. When executing the finishing command data recorded in a numerical information-recording medium if the driving axis exceeds the previous set clamp coordinates this driving axis is clamped by those coordinates. The clamp-coordinates are changed sequentially by a clamp-coordinates-changing means, so that many ways of rough machining can be performed by use of the command data for finishing.

Abstract: Procédé de formation d'une valeur théorique d'un dispositif de réglage, respectivement de commande pour la température aller d'une installation de chauffage en tant que fonction de la température extérieure. De telles valeurs théoriques sont normalement données au régulateur sous forme de courbes de chauffage. Les courbes de chauffage sont des relations non-linéaires et il est difficile pour un régulateur de les traiter en tant que telles. Grâce à cette invention, la courbe est fractionnée en deux droites de pentes différentes qui se rencontrent en un point commun. Ce point se situe là où la relation entre la courbe de chauffage et la relation linéaire passe par un maximum par rapport à la température extérieure.
