Abstract: A composite hull construction includes a metallic skeletal frame of truss-like configuration including a longitudinally extending keel plate, first and second side wall structures extending upwardly from opposing side edges of the keel plate assembly, and a top wall structure extending between upper portions of the first and second side wall structures. A synthetic foam shell entirely encapsulates the side and top wall frame structures and covers the interior surfaces of the keel plate assembly. The foam shell rigidly fixes the frame members in position and increases the compressive strength of the skeletal frame to prevent buckling of the side wall and top wall structures. An exterior fiberglass skin covers the side walls and the top wall to provide a water resistant covering over the foam shell and skeletal frame.

Abstract: A water saving toilet construction includes a toilet unit which is adapted for flushing with less than approximately one gallon of water, a holding tank which is located beneath the toilet unit and a macerator discharge pump assembly which is operative for macerating waste effluent from the holding tank and discharging it into a sewer line. The holding tank has a volume of at least approximately two and one half gallons so that a sufficient volume of waste effluent can be discharged from the toilet at one time to minimize the potential for clogging the sewer line.

Abstract: A prosthesis for maintaining the male penis in an erected disposition during sexual intercourse includes an open ring-like end portion which is receivable in substantially encircling relation on the shaft of a penis adjacent the base of the glans, a pair of support wire elements which extend rearwardly from the end portion along the underside of the penis and along opposite sides of the scrotum to points therebehind, and a retaining ring slidably received on the support wire elements and positionable thereon adjacent the end portion for closing the end portion around the penis. The prosthesis further includes a resilient band element which is securable to at least one of the support wire elements behind the scrotum and postionable so that it extends over the upper side of the penis adjacent to the base thereof for urging the penis forwardly and also slightly upwardly.

Abstract: A composite hull construction for boats and the like is disclosed. A rigid inner box-like structure of steel or aluminum is provided and acts as the main structural element of the hull, a rigid synthetic foam core being intimately bonded to the exterior surfaces thereof. The exterior surface of the foam material is easily formed as desired to define the outer configuration of the hull and a layer of resin impregnated glass fibers is layed-up over the foam to provide a protective outer skin for the hull.
