Abstract: A mushrooming bullet having a highly improved performance in the retention of the lead core within the bullet jacket subsequent to impact, and in performing effectively over a substantially wider velocity range, the bullet retaining its lead core within its jacket substantially 98-100% of its firings at high velocities, and mushrooming more effectively at lower velocities than conventionally manufactured bullets. The jacket is characterized by a base portion which has a substantially larger interior diameter than its shank portion, and a mouth portion which is substantially softer than its shank portion. The mushrooming of the nose portion of the core and the mouth portion of the jacket is effectively arrested by the harder thick shank portion when the bullet strikes a target, and thereby minimizes the loss of lead from the core.

Abstract: A one-piece toilet seat hinge composed of an elastomeric material throughout, and having the characteristics of rubber, and including a flat flange member and a coplanar support shank, the flange member being designed to be connected to the toilet seat and the support shank being generally cylindrical in shape and externally threaded to facilitate mounting thereof within a cavity normally found on the toilet stool for connection of the seat thereto. The flange member has lower peripheral portions having sufficient memory to cause the toilet seat to swing from a horizontal orientation, upon release, to a vertically extending orientation, thereby obviating the likelihood of the seat being soiled by a subsequent male urinator.

Abstract: A bullet comprised of a jacket of malleable metal having a closed nose portion encapsulating a forward core made of rubber, the nose portion having circumferentially spaced, axially extending deep scores in its nose-defining walls, and a rear core within the jacket made of a malleable metal preferably softer than that of the jacket and hard-seated against the rear of the rubber core to bring pressure against the interior surface of the meplat and the interior surface of the nose-defining walls of the nose portion, whereby upon the bullet striking and penetrating a target, the scores will rupture and the nose-defining walls of the nose portion will collapse axially and open, and together with the rubber core, will expand substantially in a radial direction to thereby provide an adequate penetration, optimum expansion bullet.

Abstract: A Sleeve Valve for regulating the water level in ponds, lagoons and other wetlands which includes an outer tubular section of plastic pipe with a plurality of vertically spaced openings and an inner tubular section of plastic pipe that is disposed telescopically within, and rotatable relative to, the outer tubular pipe. This inner tubular pipe includes a plurality of vertically spaced openings that are positionally staggered about a circumference and arranged for selective alignment with one of the openings in the outer pipe. Each of the openings in the outer pipe are sealed against the outer wall of the inner pipe until rotation of the inner pipe causes alignment of a selected opening in the outer pipe with a corresponding opening in the inner pipe, thereby allowing water to pass only through such corresponding aligned openings. The water level is regulated by selecting and aligning corresponding openings in the outer and inner pipes at the water level desired.

Abstract: A method of forming a frangible metal bullet core comprising providing an elongated inner heart member made up initially of a bundle of parallel zinc wires, twisting a plurality of zinc wires tightly around that bundle in a spiral path to cause the wires to inter-engage, deform and cohere to each other, and thereafter swaging the inter-engaged wires into the shape of a bullet core to cause the core, upon striking a target, to disintegrate into fragments smaller than the individual wires. Although copper, iron, and steel wires may be used, zinc made up of 99.99% pure zinc has been found to be preferable for forming such a core.

Abstract: A one piece shot cup (also commonly known as a shot pouch) designed especially for use in protecting the bore of a shotgun barrel when shooting hard shot made of a material such as tungsten or non-annealed steel. The cup is characterized by the use of shield members located opposite and outwardly of equally spaced tear lines which are defined by narrow areas of substantially weakened wall structure extending longitudinally of the cup. The shield members are connected to the wall structure of the tubular member only adjacent its closed rear end portion and are otherwise separate and free thereof. Portions of the tubular member extend between the circumferentially spaced shield members. The shield members prevent the shot, which ruptures the tear lines, from damaging the bore of the shotgun barrel. They also aid in holding the shot in an improved aligned relation to thereby improve the shot pattern.

Abstract: A non-toxic, highly frangible elongated soft-point training round bullet core which will disintegrate upon striking its target, for use in a training round in training exercises for law enforcement personnel and having a central heart of non-toxic metal selected from a group consisting of zinc, iron, steel, and copper with a plurality of wires of non-toxic metal selected from that group twisted around said heart throughout its length prior to being swaged into deforming and inter-engaging relation with the heart, and the core having been subsequently swaged into the shape of a soft-point nose of a bullet, with pressures sufficient to cause the strands of wire and the heart to inter-engage and deform while retaining their individuality at least to a limited extent, whereupon substantially all of the strands of the core, upon the core being fired and striking a target, will fragment along at least some of their original physical boundaries into discrete fragments smaller than the original size of the bullet.
