Abstract: In a gyrotron comprising a cathode with an emitter ring, an accelerating anode, a resonator, a collector, and an uncoupling conduit, an arrangement is disposed around the resonator which generates a solenoidal static axial magnetic constant field which, in the area of the resonator, assumes a predetermined wave form causing the electrons emitted from the cathode to move along a spiral path and which has varying localized strengths such that the electrons passing therethrough along the spiral path have, upon exiting the resonator area, only an insignificant transverse velocity component left, whereupon they are attracted by the collector which is precharged.

Abstract: In a device for transanal resectate extraction which includes a rectoscope sleeve with a proximal tubular end portion, a connecting piece sealingly mounted onto said tubular proximate end portion for closing the rectoscope sleeve and including a bore axially extending therethrough and a resectate extractor having a tubular portion extending through the bore so as to be axially movable but position-lockable therein. The tubular portion of the extractor has a protector portion at its distal end with an axial passage in alignment with the tubular extractor portion for receiving grasping pincers inserted through the tubular extractor portion. The protector portion has an outer diameter smaller than the inner diameter of the rectoscope sleeve so that it can be retracted into the sleeve.

Abstract: In a fuel injection system for an internal combustion engine with solenoid valve controlled fuel injection nozzles receiving fuel from a common high pressure fuel supply line to which fuel is supplied via a high-pressure line including a check valve by a mechanically operated high pressure piston pump which has a piston disposed in a cylinder to which fuel is fed by a low pressure fuel supply line, a control line extends between the high-pressure line upstream of the check valve and the fuel supply line and includes a solenoid valve to permit fuel discharge from the pump back to the fuel supply line and a bypass line extends between the high-pressure line downstream of the check valve and the cylinder to provide communication with the fuel supply line through passages in the piston and the working space of the piston when the piston is in its inserted position and the solenoid is open to permit the release of pressurized fuel from the common high-pressure fuel supply line to the low pressure fuel supply line.

Abstract: In a method and apparatus for making highly densified compression sheets from thermoplastic polymeric compounds preferably together with reinforcement fiber mats in a continuous fashion in a double-band press in which the compound material is heated and compressed between two compression bands which extend between reversing inlet and outlet drums and define between adjacent sections a wedge-shaped precompression zone adjacent the inlet drums wherein the compound material is increasingly compressed and also heated and a final compression zone adjacent the precompression zone, wherein the compound is heated under pressure such that the thermoplastic melts and fully wets any fibers in the sheet and an end compression zone in which the sheet is cooled which the pressure is maintained and the compound material is retained in the space between the compression bands by seal bands extending along the side edges of the compression bands and maintained in sealing engagement therewith.

Abstract: A vehicle seat support includes a support tube mounted in the vehicle body for supporting the vehicle seats. The support tube is trapezoidal in cross-section and arranged with the wider of its parallel sides on top, facing the seats. The seats are mounted on support shackles having trapezoidal cut-outs corresponding to, and receiving, the tubular support member but being of somewhat greater height to provide some clearance. A thumbscrew is mounted in the seat structure above, and directed toward, the support tube for forcing the seat support shackle into firm engagement with the support tube.
