Abstract: An overhead door and associated mating panels includes a number of hinges to pivotally couple adjacent overhead door panels. Each door panel includes a back metal skin presenting a back face. Each hinge includes a lower hinge leaf a pair of hinge legs projecting generally parallel to each other. The lower hinge leaf is mounted to the lower panel and a backer plate is mounted to the interior face of the back skin of the lower panel and screws or bolts project through the lower hinge leaf, the skin and into the backer plate. Each hinge leg on the lower hinge leaf includes a hinge pin hole near a terminal end thereof for alignment with the hinge pin holes in an upper hinge leaf. The lower hinge leaf has a tongue projecting from an upper edge of the mounting base. The tongue is formed into a hook-shaped arcuate projection and aids in the alignment, support and positioning of a hinge pin inserted through the aligned hinge pin holes in the upper and lower hinge leaves.

Abstract: A sabot and a firearm round for a firearm. The sabot includes a compression section defining a payload receiving chamber. The payload chamber receives a slug to form the firearm round. Additionally, the sabot includes a solid section connected to the compression section. The solid section can include a powder cup section for sealing ignition gasses. Typically, the sabot is formed from a high density polyethylene.

Abstract: A firing pin assembly is provided that includes a firing pin and a firing pin shaft. The firing pin is received in a slot of the end of the firing pin shaft to be retained therein with a spring retaining sleeve, a main spring, and a main spring sleeve. The firing pin is removable from the firing pin assembly and can be replaced to result in a prolonged use of the firing pin assembly. The firing pin assembly will operate as a one-piece unit when the spring retaining sleeve is oriented to hold the components securely in place.

Abstract: A universal overhead door system includes a pair of horizontal track members, a pair of vertical track members and a pair of track radius members interconnecting the horizontal and vertical track members. A pair of adjustable short radius members extend from the track radius members to guide uppermost rollers of an overhead sectional door. The overhead door system includes a pair of stationary sheaves positioned outboard of a pair of horizontal support rails which support the horizontal track members. A detent is provided at one end of the adjustable radius members to prevent undesirable travel the garage door. A spacer is provided for use in extension spring configurations when a long horizontal support rail is required. The spacer prevents metal-to-metal contact of moveable sheaves with the horizontal support rails.

Abstract: Lead free projectiles having a density less than lead, including preferred embodiments comprising a low ductility metal powder and a high ductility metal powder.

Abstract: An overhead door and associated mating panels include enhanced wear surfaces and protection against the intrusion of climatic elements or the like in the form of a combined weather seal, light block and wear insert on the upper and/or lower edges of the mating adjacent door panels. The wear surfaces are utilized during the opening and closing of the door so that frictional interaction or rubbing between the mating edges is minimized to reduce wear and damage to the panels over the service life of the door. Additionally, the wear insert portion reduces a gap between the mating edges of the adjacent panels to provide enhanced protection without requiring increased roll forming tolerances on the panel manufacturing process. Moreover, the invention includes upright projecting weather seal and light blocking portions that are positioned in a gap formed at the juncture of the mating panels. When the door is closed, the weather seal and light blocking portions are deflected.

Abstract: A solid copper hollow point bullet is disclosed wherein the effective expansion is about two times the original diameter. Over expansion and curling under of the petals formed upon impact with a target media is minimized and controlled by external stress risers and hollow point cavity geometry.

Abstract: A medical electrode assembly for an electrocardiograph or similar device is provided. The medical electrode assembly comprises an electrolyte pad having an electrolyte layer which may be secured to the skin of a patient and a backing member made from a nonconductive material being coextensively superposed directly onto the electrolyte layer. The electrolyte pad is used in conjunction with a reusable lead wire connector having at least one surface contacting the electrolyte layer of the electrolyte pad. The reusable lead wire connector includes a set of jaws which may be compressed together for contacting the electrolyte pad. The set of jaws may be formed of a nonconductive binder material having a conductive filler dispersed therein. A metallic conductive material, such as a silver/silver chloride system, is superposed over the nonconductive binder material.
