Abstract: Test set for the determination of the breakdown voltage instantaneous value of insulating media, especially for monitoring the insulation gas quality of insulation gas-filled switching installations, consisting of a high voltage generator in the form of a press-knob operated piezo element and a breakdown voltage indicator in the form of a glow lamp. The outputs of the piezo element can be applied to a spark-gap in the insulation gas space of the switching installation. The press-knob actuated piezo element generates a high voltage pulse which, in the case of insufficient insulation gas quality, generates a strike-over on the spark gap and leads to a display of the glow lamp.

Abstract: Hinged arrangement for a socket outlet box 1 designed to be installed in a floor in order to make possible the connection of leads 5 to terminals 6, 7 arranged inside the box for service leads of various kinds laid under the floor, which box comprises a preferably rectangular opening surrounded by a frame 2 designed to be fixed in the plane of the floor and provided with a lid, where the lid 3, which in a closed position rests on a ledge 8 arranged on the inside of the framework 2, is arranged by the abovementioned hinge arrangement to be able to be pivoted outwards around one side which acts as a turning axis into an open unstable position, in which position it must be held open so that it does not return to a closed position under the influence of gravity. The hinged arrangement comprises recesses 10 in the ledge of the framework close to and across the position of the turning axis, one long side of which consists of a vertical part of the frame wall and the other long side of which consists of an edge of a sprung rectangular catch 11 arranged in the ledge 8, the hinged arrangement also comprising curved arms 9 which are integrated with and attached to the lid 3 which engage with and move freely in the recesses and terminate next to the frame 2 in an end nib or stop nib 12 which engages with the wall of the frame 2 and prevents the lid 3 being pivoted past the abovementioned unstable position. This engagement with the wall of the frame can if required be inhibited by simultaneously pressing both the sprung catches 11 when opening the lid, whereupon the lid can be taken to a stable end position or can be removed. If the lid is removed, it can be refitted in the stable end position and when the lid is pivoted from the end position to the closed position it automatically reconnects the stop function controlled by the catches 11. <IMAGE>

Abstract: The present invention relates to a method and a device for speed control in high speed ratio transmissions, where the rotational speed at one side is very low and required to be variable, whilst the speed at the other side is high. The method and device according to the invention provides a continuous control of the rotational speed of the input shaft (1) as a function of an external parameter, and at the same time a very high gear ratio between the input shaft (1) and the two output shafts (6 and 8). The object is achieved by arranging all three shafts to be able to rotate simultaneously, and by controlling the rotational speed of the secondary output shaft (6) to vary, as a function of an external parameter, about a nominal speed that is a constant factor, equal to the transmission gear ratio between the two shafts (6, 8), times the rotational speed of a primary output shaft (8), making the rotational speed of the input shaft (1) a function of the difference between the speeds of said shafts (6, 8).

Abstract: The present invention relates to a method and device for interconnecting radio frequency power SiC field effect transistors. To improve the parasitic source inductance advantage is taken of the small size of the transistors, wherein the bonding pads are placed on both sides of the die in such a way that most of the source bonding wires (6) go perpendicularly to the gate and drain bonding wires (7, 8). Multiple bonding wires can be connected to the source bonding pads, reducing the source inductance. An additional advantage comes from such arrangement by reducing the mutual inductance between source/gate and between source/drain due to the orthogonal wire placement.
