  • Patent number: 6971514
    Abstract: An improved corner guard for use on a pre-hung door assembly. The corner guard of the present invention is designed for use with a pre-hung door assembly that includes a door secured within a three-sided door frame in which the two vertical frame members extend in an offset manner below the bottom edge of the pre-hung door. In a preferred embodiment, the corner guard includes a bumper member for imposing a gap between adjacent stacked assemblies. A substantially flat transition flange member is attached to one end of the base of the bumper member, and together, the transition flange member and bumper member base form a retention barrier surface across the front corner region of the pre-hung door assembly to maintain the door securely seated within the door frame. A fixed side flange is affixed to the other end of the bumper member and extends approximately perpendicularly with respect to the bumper member base surface such that a right angle inner surface corner contour is formed therebetween.

  • Patent number: 4891586
    Abstract: An electrical test probe has a electrically conductive hollow elongate body with an exterior coating of electrically insulative material. An output connector is formed by soldering an electrically conductive wire to the exterior of the elongate body. A hooked gripping tip for probing Integrated circuit devices and the like is formed on one end of a conductive shaft inserted into the elongate body. Axial movement of the conductive shaft relative to the elongate body alternately extends and retracts the hooked gripping tip out of and into the elongate body. The electrically conductive elongate body provides a low contact resistance path between the gripping tip and the output connector.
