  • Patent number: 5173037
    Abstract: An automotive fuel pump has a tubular shell, a pump group in the shell, an end housing in the shell, and an electric motor in the shell including an armature shaft. The armature shaft has an integral annular first spherical shoulder engaging a seat of a first bearing on a partition wall of the pump group. The first bearing reacts axial thrust and radial bearing forces between the partition wall and the armature shaft and supports the armature shaft on the partition wall for rotation about the centerline of the shaft and for universal pivotal movement about the center of the first spherical shoulder. The armature shaft has an integral second spherical shoulder received in a cylindrical bearing seat of a second bearing on the end housing.

  • Patent number: 5001443
    Abstract: Coaxial units are disclosed for conducting microwaves to and from amplifying apparatus with splitter and combiner cavities. Each coaxial unit comprises an outer conductor, a dielectric sleeve having an unsheathed portion extending forward of the front end of the outer conductor, and an inner conductor pin projecting forward of the sleeve, the pin having a forward portion which is resiliently compressible radially inward. The coaxial unit is coupled to an associated cavity by having its sleeve and pin forward portions, respectively, received in large and small bores respectively formed in metallic plates on opposite sides of the associated cavity. The forward portion of the pin makes direct yieldable-pressure electrical contact with metallic regions around the wall of the small bore at a location adjacent the opening of such bore into the cavity.
