  • Patent number: 5122926
    Abstract: A housing for an electric device, such as a power transformer or an X-ray tube, comprises a tank which contains electric components of the device and which is filled with an insulating and/or cooling liquid, such as. A lid is arranged at a planar top portion of the tank and hermetically sealed thereto. The lid is at least partially flexible for enabling movement of the lid when the liquid expands and contracts due to heating and cooling, respectively. In a preferred embodiment, the lid comprises a gasket at its periphery and a rigid portion at its center. A frame can be provided for pressing the gasket against the tank. At the frame, at least one rod or spring can be fastened for guiding the movement of the lid perpendicular to the plane of the planar top portion.

  • Patent number: 4627157
    Abstract: A crimping block is positioned immediately adjacent to one side of a circuit board having predrilled apertures therein through which the electrical leads of a circuit component are inserted. The crimping block includes a plurality of linearly displaceable crimping pins, each having an upper, beveled end adapted to receive, deflect and crimp an associated component lead inserted through an immediately adjacent circuit board aperture. Upon contact with an inserted component lead, the crimping pin is displaced downward a predetermined distance. During downward displacement of the crimping pin the electrical lead is deflected laterally followed by the upward deflection of the electrical lead upon the end of crimping pin travel. Upon the end of crimping pin travel, its beveled, upper end crimps the electrical lead in tight fitting relation with a circuit board-mounted conductor.
