Abstract: A memory disk having a central opening and planar sides for receiving magnetic media on both of the sides is bounded by a cylindrical outside diameter peripheral edge and chamfered edges extending between each of the planar sides. The peripheral edge is clamped by a disk processing chuck including a disk retainer mount having a central disk support for mounting a circular disk edge bounding the central opening and a mount cylindrical beveled edge receiving an outside diameter chamfered edge of the disk. A ring in the retainer mount includes a multiplicity of spaced radial fingers extending cylindrically around the ring, each finger having a distal end extending to a first position outboard of the disk peripheral edge. The distal ends are moveable inwardly to a second position by an inflatable bladder acting simultaneously against all the fingers, placing the distal end tips into clamping contact with the disk peripheral edge mounted on the retainer mount.

Abstract: A plurality of unidirectional valved intake gate units are essentially horizontally disposed, operate independently, and are located upstream of an input penstock. They are adapted to intercept waves and convert their kinetic energy to drive a turbine. Each gate unit comprises a movable gate that is horizontally hinged and adapted to permit the incoming waves to slide over the upper surfaces of the gates and into the penstock. They are constructed so that the back pressure of the penstock pushes the gates upward directing the remaining forward moving wave energy to higher elevations increasing the water level height in the penstock.

Abstract: An inside garment waistband belt loop arrangement whereby the belt loops are secured at the bottom on the inside garment waistband and free to float inward at the upper loop end permitting a belt inserted therein to grip around individual's body waist free of gathering garment waistband.

Abstract: A power operated bed whereby the sides with mattress move from a normal position to a vertical position for supporting a person's spinal column simultaneously in two distinct planes relieving pressure on the occupant's spinal column. And a bed incorporating a headboard of independent turned spindles and adjustable straps to aid the occupant in shifting body position by the use of ones hands and arms and to further provide body anchors that allow stretch of occupant's spinal column. An arrangement allowing bed sheeting to remain firmly taut to the mattress independent of bed positioning.

Abstract: An assembly intended to reduce the water splash and throw from operating highway transport trucks in wet weather conditions by the installation of replaceable sectionalized wheel skirts that modify vacuum/suction/pressure conditions within and about the skirt.

Abstract: A convertible moveable transparent sail adapted for bicycle to increase forward thrust, journaled for repositioning by cyclist in operation and readily reconfigurable for stowage.

Abstract: This invention is directed to a chemical aided water closet odor neutralizing device. The odor neutralizing device is located or mounted between the water closet and the water closet seat and is characterized by having a suction cavity on one side of the seat and a pressure chamber on the opposite side, including a chemically saturated filter whereby in operation, a circulating air blanket is created over the bowl combining chemically the escaping gases and thereby neutralizing their offensive odors.
