Abstract: A casing (1) for housing electrical and/or electronic components (6) surrounded by a cooling medium (10), the said casing consisting of a frame (2) and an upper and a lower closing-wall part (3, 4), is constructed in such a way that the frame (2) and/or one closing-wall part (3, 4) consists of electrically insulating, castable material and comprises electrical connecting parts (50) integrally cast in the said material, the frame (2) and the closing-wall parts (3, 4) jointly enclosing, in a pressure-tight manner, a housing space which can be filled with a coolant (10) for the boiling-bath cooling of the electrical and/or electronic components (FIG. 1).

Abstract: A power generator drives a rotating anode of an X-ray tube via a stator-rotor in which the stator receives the anode side high voltage potential. An isolating transformer is connected to an alternating current source which converts DC voltage to AC voltage via a rectifier bridge, a regulator and a switching inverter. The secondary winding of the isolating transformer is coupled to a second rectifier bridge for applying rectified voltage to a second switching inverter that generates the alternating currents for the stator windings. The second inverter receives the high voltage which is also applied to the tube to generate X-rays.

Abstract: A flat fuse including two plug blades arranged next to one another in the same plane, being spaced from one another. The plug blades are fabricated from stamped sheet metal parts, the plug zones of which extend, in each case, rearwardly in a one piece construction into current-conducting straps. Between the straps, there is arranged a fuse fusion wire which is fastened to the straps. The current-conducting straps and the fusion conductor are surrounded by and enclosed in a plastic casing. The fuse fusion wire includes a copper wire with a silver sheathing, and the current-conducting straps as well as the plug blades are fabricated from brass, in which arrangement at least the current-conducting straps, but preferably also the plug blades, are superficially tinned. The fusion conductor is welded, in each case, to a flat side of the current-conducting straps.
