Abstract: A folding anchor, having a shank formed in two pieces and pivotally joined together with a spring biased locking device. The fluke assemblies are pivotally connected via a coupling assembly at the lower end of the shank, the coupling assembly including first and second generally C-shaped retaining members for pivotal attachment of one fluke assembly to each, the first retaining member being secured to the lower shank, with the second retaining member pivotally connected to the first for pivoting about an axis generally perpendicular to the axis of pivoting of the flukes. the two retaining members are so formed, and joined, to permit pivoting of the fluke assemblies between folded and unfolded positions, whereby the two flukes may be rotated toward each other into proximate facing relation, or away from each other into alignment.

Abstract: A power generating apparatus including a watertight sealed buoyant vessel of cylindrical form having an external stabilizer for directing the vessel into the current. Internally, the vessel is provided with a supporting structure on the axial centerline for rotatably supporting the axle or pivot shaft of a lever arm having a weight at the end thereof, the weight being supported on a circumferential rail assembly adjacent the upper end of the vessel. The weight is freely rotatable in either direction thorugh 360 degrees. The lower end of the shaft is coupled to a piston type hydraulic pump, which draws fluid from a reservoir, and pressurizes the fluid into a two stage accumulator, the controllable flow therefrom actuating a hydraulic motor coupled to an electrical generator, Fluid from the hydraulic motor then returns to the reservoir for further usage.

Abstract: A field portable dental chair, collapsible to suitcase size, with pivotable outriggers for support, the chair including a bellows arrangement with a telescopic internal structure for raising and lowering the seat of the chair. The apparatus is formed, in part, of rigid members and, in part, flexible members contained within the rigid members for portability. Inflatable cushion members are provided for support of the head, back, seat and legs of a patient.

Abstract: A folding anchor having a shank formed in two pieces and joined together with a keyhole fitting, and, upon pivoting the upper shank abuttingly overlies the lower shank. The fluke assemblies are pivotally connected via a coupling assembly at the lower end of the shank, the coupling assembly including a retaining member for pivotal coupling to the fluke assemblies and a slide block member having a passage for receiving the retaining member therein, displacement of one relative to the other enabling pivoting of the fluke assemblies between folded and unfolded positions, this being accomplished by 90 degree pivoting of the fluke assemblies about first axes generally parallel to the longitudinal axis of the shank, whereby the two flukes may be rotated toward each other into proximate facing relation, or away from each other into alignment.

Abstract: A coolant hose clamp, in which an outer ring is provided with an inner cam surface configured for radial displacement of a plurality of arcuately configured clamping shoes, positioned within a retaining ring assembly. Rotation of the cam ring by a simple turning motion through a small angle relative to the retaining ring assembly actuates the clamping shoes radially inwards into clamping engagement with a flexible hose on a rigid fitting.
