Abstract: A convertible panel door-screen door closure for residential garage doors or commercial doors having a torsion spring mechanism for balancing the panel door and a roll-up mechanism for the screen door. The roll-up mechanism is mounted beneath the torsion spring mechanism on header plates. Roller tracks for the panel door are mounted in spaced relation to the standard door jams by brackets and the tracks for the screen are mounted between the jams and the panel tracks on the same brackets. The screen door and panel door have the same position with respect to the jams, immediately to the rear of the jams, when in their down positions, and hence only one door may be in the down or closed position at any time.

Abstract: A hoist ring assembly for transporting loads, including an anchor bushing that is threaded into the load and forms the pivot for a releasable swivel hanger assembly with a shackle connectable to an overhead hoist. The swivel hanger is quickly attachable to and detachable from the anchor bushing to expedite load movement. The hanger swivels on the anchor bushing in a side-pull action and has a key hole slot that hangs the anchor bushing during use and permits the hanger to be rapidly removed from the anchor bushing when the hoist is slack. A latch lever holds the hanger in its attached position on the anchor bushing when unloaded and is quickly flipped out of the way for swivel hanger removal.

Abstract: A toilet plunger holder and cover including a cylindrical base coextensive in height with the plunger elastomeric head and a cover for the base with a narrow tubular portion that covers and is coextensive in length with the plunger handle. Partitions and a deodorizing substance holder are molded integrally with the base bottom wall, and these partitions hold the plunger head above the bottom wall for drying. The entire holder receives a rigid decorative overlay that is connected to the holder cover so the overlay and cover are removed as a unit from the base. In one embodiment, the holder cover is made of a ceramic material with an elastomeric bumper that prevents damage to the ceramic.

Abstract: A hoist ring assembly for transporting loads, including an anchor bushing that is threaded into the load and forms the pivot for a releasable swivel hanger assembly with a shackle connectable to an overhead hoist. The swivel hanger is easily attachable to and detachable from the anchor bushing to expedite load movement. The hanger swivels on the anchor bushing in a side-pull or center pull action and has diametral retractable locking pins that enter the anchor bushing in the attached mode that when retracted permit the hanger to be rapidly removed from the anchor bushing.

Abstract: An internal combustion engine component assembly including piston, wrist pin, and cylinder sleeve, all constructed of a matching carbon--carbon composite is disclosed. The piston is a two-piece assembly divided in crown and skirt, each fabricated individually to optimize the most desirable properties in the respective cylinder areas in which they operate. The crown is fabricated by placing the fiber and binder into a compression mold and pyrolizing(heating) the resulting preform at a high temperature in the range of 1500 to 2000 degrees C. to achieve high temperature strength, and high thermal conductivity that continue after machining to the finished crown part. The skirt, a separate piece, on the other hand is fabricated differently to seek higher lubricity and better wear resistance along the cylinder wall with lower thermal conductivity to minimize heat loss.

Abstract: A hanger assembly for attachment to heavy loads in material handling systems such as overhead conveyors where the hanger must be angularly aligned with the conveying element such as an attached cable. The hanger includes a base, a threaded stud for load attachment, and a hanger such as the eye in an eyebolt assembly, an example of a hanger assembly. A washer positioned around the threaded stud between the base and the load is hardened substantially less than the hanger itself enabling the hanger to be rotated up to 180 degrees after initial tightening without over torquing the threaded stud. The washer has a plurality of radial slots in one face that maintain the structural integrity of the washer under high rotational and compression loading.

Abstract: A micro switch for detecting forces in two orthogonal directions, rather than one, useable, for example, to detect out of size parts in one plane in a multiple spindle screw machine, and disengaged parts in an orthogonal plane. This is accomplished through the provision of a ramp that is slidably engaged by the switch's actuation rod as the rod moves in a first plane to translate sideway movement of the rod into perpendicular linear movement of the switch's plunger. The ramp has a recess that captures the rod as it moves in the orthogonal plane, which is coincident with the axis of the plunger, thereby causing switch actuation with plunger movement in two planes.

Abstract: A golf swing training system with a floor mounted base and a pelvic belt that wraps around the golfer's hips and guides but not unduly restricts the golfer's pivot during the back swing and follow through. The system encourages a pelvic pivot about an axis to the rear of the golfer's right leg in the back swing and down swing, and a pivot about an axis behind the golfer's left leg in the follow through. A multiple pivot mechanism that connects the belt to the base inhibits lateral movement of the hips during the back swing and down swing. The belt is connected to the base by an expandable link pivotally connected at one end to the base and pivotally connected at its other end to the belt, both about generally vertical axes. As the golfer initiates the back swing, the belt pivots about the second axis as the link pivots in the opposite direction about the first axis.

Abstract: An accessible fish lure holder releasably attachable to a boat's gunnel by suction cups. An elongated horizontal bar is supported on the suction cups that curves a cylindrical foam sleeve into which the fisherman drives the lure hooks. The foam holds the hooks securely but permits their easy removal when the fisherman wants to fish with. The suction cups also act as shock absorbers for the bar and foam sleeve to minimize inadvertent lure drop-off and the foam is rotatable on the bar to turn a fresh undamaged part of the foam upwardly after the upper part of the foam becomes torn with use.

Abstract: A hoist swivel shackle assembly used with others to hoist heavy objects such as dies and molds. The shackle includes a "U" shaped shackle member pivotal on a swivel body which is rotatable about an orthogonal axis on a base. Long term distortion of the shackle member is minimized by flanges on the ends of the legs of the shackle that slidably engage side bosses on the swivel body to absorb outward loading on the shackle. The shackle is pivoted to the swivel body member by a pair of pins with annular recesses, fixed in a pair diametrally opposite pin receiving bores in the swivel body member. These pins are held in the swivel body member by pressing a softened material into threaded bosses in the swivel body forcing it around the pins and into their recesses. Overloading the swivel shackle assemblies is minimized by an indicator that tells the operator when he has exceeded the safety angle of the shackle member.

Abstract: A golf club head with a shortened hosel and extended ferrule including a hollow body having a ball striking wall, and a top wall extending rearwardly from the ball striking wall. The hosel extends downwardly from the top wall with a shaft receiving bore therein, and extends upwardly from the top surface of the club a much shorter distance than conventional with a flat top surface much larger than normal and an annular outer surface that flares sharply outwardly. The ferrule head in some embodiments has a larger than normal lower surface equal in size and shape to the hosel top surface with an outer surface that curves sharply outwardly and downwardly in lower portions thereof in a smooth transition into the hosel outer surface. The top of the hosel bore is chamfered, and the ferrule is epoxied not only to the inserted shaft but also to the enlarged hosel top surface to increase the hosel's ability to absorb side loading from the inserted shaft.
