Abstract: A bed which is pivotable from a horizontal arrangement to a vertical arrangement to controllably invert a human body from a supine position to an inverted position. The arrangement of the bed is controlled by at least one electric actuator so that injured or ill persons may attain the inverted position safely and easily. Hanging by their legs, users are suspended in the inverted position by a trapeze bar which is supported within a rotatable leg attachment; by adjusting the position of the trapeze bar and the angle of the leg attachment, selective stimulation may be applied to targeted acupressure points. A heating and/or vibrating unit may be included to provide further stimulation to the spine.

Abstract: A small waterplane area multihull (SWAMH) vessel having an upper hull platform located above the design water line of the vessel which is maintained above the surface of a body of water by at least two cylindrical submerged hulls joined thereto by supporting struts. A buoyant core material is contained between inner and outer walls of the submerged hulls which define a cylindrical space in which a rotary propulsive means is housed. An engine means is situated on the surface platform and is joined to the rotary propulsive means through a work translating means which converts the output of the engine to provide a propulsive force.

Abstract: A sturdy, reusable and collapsible viewing instrument for assisting in viewing distant objects that is assembled from a blank. The blank comprises two pivoting frames in which ocular and objective lenses are affixed. Domains of the blank are foldable along pre-etched fold lines to form parallel sides of the viewing instrument. Ideally, the blank dimensions approximate those of a standard credit card so that the viewing instrument may be stored in one's wallet or purse.

Abstract: A writing instrument that may be secured or attached to an article, such as a credit card. The inventive writing instrument is configured in the form of a cylindrical casing having at least two opposingly biased resilient jaws or projections extending therefrom, a writing element disposed within said casing and a cap for covering the writing point of the writing element. A credit card or similar article can be easily and conveniently inserted between the resilient jaws or projections and will be securely retained therein.

Abstract: A vehicle back-up safety device comprising a sensing system for detecting the presence of an obstruction within a prescribed area behind the vehicle while a user is driving in reverse. In response to a signal from the sensing system signifying the presence of a an obstruction, a control means activates a pair of electrically-motivated plunger assemblies to force fluid into the vehicle's brake line system, thereby activating the vehicle's brakes.

Abstract: A tool-toting device facilitating the carrying and retention by a workman of a hand tool having a clip for attaching the device to a belt such as a workman's tool-belt. A rigid hook depends through fastening means from the clip and has the ability to swivel as the workman moves to maintain the center of gravity of a tool attached to the hook. Rigidity of the hook ensures that the workman will be able to replace the tool onto the toting device or to remove it therefrom singlehandedly. Further, the hook is rotatably positionable to permit the workman to position his tool in a comfortable fashion.

Abstract: The present invention relates to a multipurpose drilling tool that may be cycled between drilling and underreaming operations while situated in a well bore. More specifically, the present invention provides a multi-purpose tool in the form of a housing member comprising a central bore, four extensible underreaming blades and means for attaching a standard drill bit. The ability of the multipurpose drilling tool to cycle between drilling and underreaming modes is provided by means of a piston which is motivated downwardly and rotationally by fluid pressure and is directed by a piston travel guide from a first relaxed position to either a drilling position or an underreaming position. The present invention enables cycling of the tool within the well bore without requiring the removal of the tool and drilling string from a well bore, thus increasing the efficiency of drilling operations.

Abstract: The present invention provides a hand-powered tool facilitating the translation of rotary motion of a workman's arm through an angled shaft which may rotate freely with respect to a handle. The angled shaft has three coplanar bends resulting in a stretched "Z" configuration in order to allow the user to apply a great torque about a circle which his hand easily can describe and which is translated through the shaft to the subject fastener or surface point. The shaft is rotatably mounted to a handle through a bearing thereby enabling full rotation of the shaft with respect to the handle and permitting the user to complete a rotary cycle without release the tool. A hollow tip is disposed at one end of the tool within which interchangeable bits may be installed. An auxiliary handle releasably attached to the shaft also is provided for use in situations where a greater torque is required.
