Abstract: A reversible drive mechanism for socket wrenches, having a detented selector cap thereon. The socket driving post of the wrench is fixedly attached to a triangular shaft rotatably contained within an internal cylindrical bearing surface, which in contained within the head of the wrench handle. Each face of the triangular shaft is a convex arc-shaped surface, and the cylindrical surface and the convex surfaces create between them three lune-shaped spaces. Each of the convex faces on the triangular shaft has tiltably mounted thereon a U-shaped fixture, which loosely contains within its arms a cylindrical roller. As the selector cap is rotated back and forth between selector positions, each U-shaped fixture tips back and forth on its respective convex face, and shifts the contained roller from one extreme to the other of its respective lune-shaped space.

Abstract: A reversible drive mechanism for socket wrenches, having a detented selector cap thereon. The socket driving post of the wrench is fixedly attached to a triangular shaft rotatably contained within an internal cylindrical bearing surface, creating three arc-shaped spaces. The cylindrical surface is the inner surface of the head of the wrench handle. Each of the surfaces on the triangular shaft has tiltably mounted thereon a U-shaped fixture, which loosely contains within its arms a cylindrical roller. As the selector cap is rotated back and forth between selector positions, each U-shaped fixture tips back and forth on its respective triangular surface, and shifts the contained roller from one side to the other of its respective arc-shaped space.

Abstract: The present invention is an economical and conveniently installed support for flanged piping where the individual lengths thereof are bolted together. It is intended for use on long, substantially horizontal, runs of piping where it is desired to eliminate stresses on unsupported flanged joints, and is especially useful where valves and other heavy fittings are located between lengths of piping. The support is bolted directly to the bottom arc of the flange, having holes therein which match the holes in the flanges, and is especially useful with piping having Class 125 AWWA flanges. The support has convenient adjustments to compensate for variations in the height between the level of the piping and that of the supporting structure.

Abstract: The disclosure relates to a hypodermic syringe which is stackable, disposable and non-reuseable with features to prevent users from accidentally stabbing themselves before or after use; insert the needle with preferred orientation; render is unusable after use; measure precise amounts of injected or withdrawn fluid and retract the needle with one finger after use.

Abstract: The present invention is a buffing kit for use by farriers to impart a high gloss to the hooves of horses and other hooved animals, in competitions and exhibitions. It consists of several rectangular blocks of resilient material having replaceable sheets of abrasive material on the two major faces. The blocks should not be deteriorated by water and soap, and are sized to be easily hand-held. The abrasive material ranges from approximately 100 grade to 3600 grade. In use, the farrier wets the abrasive surface and, starting with the coarsest grade, removes the major roughnesses by a buffing procedure. Progressively finer grades are used in turn to obtain the desired finish. Preferably, the two finest grades do not differ from one another substantially. Worn-out sheets are replaced by fresh. Three blocks, with a total of six major surfaces, provide a satisfactory progression in abrasive grades to obtain almost any desired gloss, and will service about five horses.

Abstract: The present invention provides an alarm when a patient, supposed to remain in a specific position, changes to one which is undesirable. For example, it could be used for patients, supposed to remain recumbent, who become upright or in a position which is preparatory to becoming upright. It can be incorporated into a cuff, vest, panty, or the like, and includes energy source, alarm, on-off switch, and one or more position-sensitive sensors with interconnecting circuitry, so that the alarm is actuated whenever the patient changes to an undesirable position. An embodiment including a plurality of sensors, appropriately interconnected, avoids false alarms by permitting positions which might actuate a single sensor. The alarm can be audible, visual, tactile or other type, and can be located on the patient or at some remote location, connected directly or by wireless.

Abstract: A wave-forming generator for generating inclined surfaces on a contained body of water. The water is propelled against the surface-shaping generator with sufficient force to impart the desired shape to the water surface, and the generated surfaces can include waves, such as tunnel waves, appropriate for surfing and other water skimming manuevers on the surface of a body of water. Surfaces generated can require a wide range of skills to negotiate, from beginning to advanced levels. The surfaces generated are substantially stationary with respect to the water containment means, the water itself moving with respect thereto.
