  • Patent number: 5171325
    Abstract: A prosthetic joint includes an anterior linking and support member and a posterior linking and support member, formed of a resilient material, which act as cantilever flat springs to provide an intrinsic extension bias while furnishing the rigid structure necessary to support the axial loads and extension moments induced by the amputee. A prosthetic knee joint includes a base formed of a resilient polyamide such as nylon 6/6, from which an anterior linking and support member, generally of an L-shape, and a posterior linking and support member, monolithically extend upwards. Formed to provide the inherent stability of four-bar linkage, these resilient linking and support members are pivotally attached to a yoke member to act as cantilever single-leaf flat springs which provide an intrinsic extension moment to the prosthetic knee joint which may vary according to the amount of flexion of the knee joint.

  • Patent number: 5157892
    Abstract: The invention involves a structural interlocking joint system for structural panels used in building construction. A skeleton is formed of interlocking ribs which engage panel skins which are grooved in a pattern to receive the edges of the interlocked ribs. The grooves of each panel skin are formed with their edges angled away from the groove to provide both a wider opening for insertion of the rib skeleton into the grooves, and to provide, after such joining insertion, a reservoir for any excess glue forced out by the joining process. Along the longitudinal edges of the ribs is formed a uniform channel which provides a defined reservoir for glue of substantially even width and depth between the edge of each rib and the bottom of the corresponding groove within the skin. Thus, in the insertion of a rib within a groove, the glue is directed into a substantially uniform strip within the rib edge channel, maximizing strength and minimizing localized glue overflow.

  • Patent number: 5145133
    Abstract: A folding target holder involves a hinge board with two front legs fixedly attached thereto and a rear leg pivotally attached therebetween and having an upper bevelled surface which, in the unfolded position, abuts the hinge board. In the folded position, the rear leg pivots to a co-planar position between the front legs. The legs are each individually adjustable in length. A target board is hinged at an edge to the lower edge of the hinge board so that, in the folded position the target board extends downward in the same plane as the hinge board and lays against the front legs and folded rear leg. When unfolded, the target board pivots upwardly with its lower portion lying to the front of the hinge board. A separating member positioned within the angular gap between the target board and hinge board serves to physically block any further decrease in that gap.

  • Patent number: 5088372
    Abstract: A slicer blade for cylindrical potato strips includes a plate member having a plurality of closely spaced cylindrical holes formed therein. The edge of each hole is beveled, as by a countersinking-type bit, preferably with the beveling tool being inserted into each hole the same distance, so that the surface of the bevel at least reaches the center point of the triangular space between each cluster of three holes. The previously flat triangular space thus is transformed into a three-sided sharp pointed peak. Additionally, the beveling creates an edge between the holes which also becomes sharpened to the same slope or angle as the peak. The edge between each pair of adjcent holes is formed into a concave shape which curves upward to the sharp-pointed peak. The combination of closely positioned holes and the beveling of each hole produces a sharp cutting edge about the perimeter of each hole without leaving any surface of the slicer blade which is transverse to the flow of the potato.

  • Patent number: 5064067
    Abstract: A Christmas light organizer provides a frame for the handling and storage of a string of Christmas lights. A generally rectangular, planar frame includes two opposing sides having a series of tooth-like projections extending outwardly from the frame which are longitudinally bevelled, having an inner gap between projections at their base which is less than a least thickness of the electric cord and an outer gap at their ends which is greater than the greatest thickness of the electric cord, thereby allowing a Christmas light cord to be inserted and guided between the converging faces of adjacent projections until the cord is securely gripped therebetween. The other two, non-toothed, sides may have one or more sets of divergent, slanted notches intruding from the inner side of the frame and formed so as to hold, at the plug, an end of the electric cord. A handle may extend outwardly from one of the non-toothed sides. Cross braces may be added across the inside of the frame for both strength and safety.

  • Patent number: 5026593
    Abstract: A reinforced laminated beam provides reinforcement in the locations where maximum tension occurs on such beams, generally at the lower portions of the beam, by the addition of a layer of high tensile strength material between successive layers or laminations of wood. A thin layer of high tensile strength material, preferably a strip of aluminum alloy with a tensile yield strength of approximately 41,000 psi and a thickness of 0.064-inch, which is continuous across the width and length of the beam, is adhesively fixed between the bottom two laminations of wood, thereby producing a significant increase in the carrying capacity of the beam, while providing no obstacle to the sawing or other working of the beam in the field. Reinforcing material also may be added between other lower laminations for additional reinforcement, this being particularly useful for deep beams having a large number of laminations.
