Abstract: Pour nettoyer des pièces à usiner après leur soudage, notamment des plaquettes de circuits imprimés ou des groupes de composants équipés, on lave ces pièces avec un liquide inerte de nettoyage maintenu à une température légèrement inférieure au point de fusion de la soudure. On peut ainsi renoncer à l'utilisation de solvants polluants pour dissoudre des impuretés et des décapants. Ce procédé de nettoyage est particulièrement avantageux après un soudage en phase vapeur, étant donné que l'on peut utiliser comme liquide de nettoyage le liquide qui sert d'agent caloporteur dans l'installation de soudage en phase vapeur, ce qui élimine le problème du mélange indésirable de milieux de traitement différents (agent caloporteur d'une part et liquide de nettoyage d'autre part).

Abstract: During the tracking of low-flying targets, the accurate angle measurement by means of a conventional monopulse radar device is made virtually impossible due to multi-path reception, especially over water surfaces. The cross-feed method, a method for correcting the mirror effect, supplies a corrected angle error signal which allows the position of a flying object to be accurately determined. These differences by 0 DEG  and by 180 DEG  of the direct radar echo signal relative to the reflected radar echo signal have a disadvantageous influence on the results of the cross-feed method in this arrangement. According to the method according to the invention, the areas of disadvantageous phase angles are restricted by switching the transmitting frequency between at least two frequencies. According to a further method according to the invention, radar echo signals with disadvantageous phase angle can be detected and masked out. <IMAGE>

Abstract: A panel-mounted switch, whose switch mechanism consists essentially of a rotatably supported contact lever (2) and of a manual operating device (3) which is connected outside its rotation bearing (4) in a rotationally moving manner to the contact lever, by means of a switching rod (5) in the manner of a bell crank. The rotation bearing (6) of the contact lever is formed by the switching rod (5); the contact lever is guided in a link (10). The contact-free arm (8) of the contact lever (2) can set itself freely within a wide range, determined by the contact opening movement. When the contact opens, a rolling movement takes place initially with large opening forces and then sudden opening. During closing, large contact forces are achieved in the final phase. The current-carrying capacity is thus large. <IMAGE>
