  • Patent number: 4895527
    Abstract: A safety cover for a dual outlet receptacle including a planar peripheral base edge, a central face panel offset laterally from the base edge and integrally jointed thereto by peripheral side panels. The face panel is inclined to define a tapered chamber of approximately maximum depth over one outlet and minimal depth over the second outlet. An elongate aperture is defined through the face panel at a position generally corresponding to the maximum depth of the chamber and is configured to allow passage of the plug in one rotated position thereof and to preclude retraction of the plug upon rotational alignment of the plug for engagement with the corresponding outlet. The second aperture through the face panel is of a size, and so aligned with the second outlet, as to allow for direct engagement of a plug therethrough and into the outlet.

  • Patent number: 4895549
    Abstract: A universal joint for a highly stressed cardan shaft possesses, in order to increase the rigidity and load-bearing capacity of the bearings in the trunnion cross bearing, a tie-rod which extends through a central longitudinal hole through two opposing trunnions. The bearing covers of the two opposing bearing eyes are fixed to the tie-rod under pre-stress and bear from outside against the outer ring of the radial bearing. The bearing covers carry tracks on the inner sides for the axial bearing arranged in the region of the trunnion end face. The transverse forces are thus passed to the respectively opposite joint yoke half, so that no deformation arises to spray the joint yoke. As a result the formation of axial play is prevented, and all bearings are uniformly stressed, as a result of which greater load-bearing capacity and longer service life are obtained.

  • Patent number: 4895566
    Abstract: A medical device having long-lasting bactericidal properties and a method for making the same is provided. The material from which the medical device is made, the substrate, carries a negatively-charged group having a pKa of less than 6. A cationic antibiotic is ionically bonded to the negatively-charged group. The negatively-charged group may be a portion of a larger carrier molecule. The carrier molecule is bound to the substrate such that the negatively-charged group is exposed for ionic interaction with the cationic antibiotic. Heparin is an ideal carrier molecule because it has both anti-bacterial adhesion activity and anti-thrombogenic activity.

  • Patent number: 4895573
    Abstract: A femoral-side hip-joint prosthetic device for use in hip-joint replacement. The device includes an elongate stem whose surface defines maximally spaced infero-medial and supero-lateral surface curves, and which is characterized by a surface rotation which carries the supero-lateral surface curve about 15.degree.-30.degree. forward with respect to the infero-medial surface curve, on progressing upward along the upper surface portion of the stem, with the device in operative position. The rotation of the stem surface produces a close approximation to the cavity formed in the proximal femur by removal of the cancellous bone in the natural cavity formed by a wall of densified cancellous bone. A 3.degree.-15.degree. proximal anteversion of the neck is adapted to place a hip-joint ball carried on the stem at a position closely approximating that of the head in the natural femur.
