Abstract: Clay target/pigeon throwing machines/traps used is the activity of sport shooting. The clay targets being circular and somewhat disc shaped. More particularly, the clay target throwing machine is adapted to optionally and automatically throw, simultaneously, two targets. When the machine is set to throw one target it is designed so that each successive target which is thrown is directed in a direction which is randomly generated so that the target direction is not predictable by the shooter as he/she is triggering the throw of the target by the machine. Additionally, a plurality of targets may be loaded into an indexing carousel which automatically indexes either one or two of the targets to the load position and stays in position while an "elevator" lowers the target or targets into the firing or throwing position.
Abstract: A teaching apparatus or teaching tank which has two, a front and a rear, substantially planar walls at least one of which is transparent. A plurality of bolts and spacers, or molded fasteners are used for holding the front and rear walls in parallel opposed spaced relationship to form the tank volume which tank volume is defined by the planar dimensions of the front and rear walls and the tank cavity width which width is determined by the spacers. The tank side walls and bottom are formed using flexible and deformable tubing, such as PVC tubing which is sealingly compressed by the front and rear walls when they are assembled and defines in combination with the planar walls, at least one working cavity having a working cavity volume. The volume and/or volumes is/are variable and a function of the placement of and the dimensions, the length and the OD, of the tubing and the area of the planar walls.

Abstract: A fastening device or apparatus wherein mechanical connection and/or disconnection or electrical connection and/or disconnection is accomplished as a result of the deformation of an oval/ellipse shaped component--the deformable component--which may preferably have an elliptical aperture therethrough. Deformation may result from the application of a deforming force which causes the decrease in length of the major axis and a consequent increase in length of the minor axis of the ellipse. The deforming force may be applied by any known means such as by magnetic fields applied where the deformable component may have incorporated therein material which is sensitive and reactive to such magnetic fields or by the application of mechanical pressure from a piston driven by magnetic forces or hydraulic forces and/or forces created by temperature changes such as are known and found in a class of materials characterized as "SHAPE MEMORY ALLOYS".

Abstract: The present invention provides a process for the electroless plating of easily reducible metals onto ultrafine, usually inert, particles. Such plating is achieved through careful and accurate control of such parameters as the feed rates of the various solutions, the control of pH of the solution, the temperature, pressure and the rate of agitation of the solution in which the plating is taking place. The plated ultrafine composite particles and the powders made from the particles produced by the process are also a part of the invention. There is also provided a metal article of manufacture consisting of a metal such as copper, silver, gold, ruthenium, rhodium, palladium, osmium and platinum with a plurality of spherical shaped ultrafine particles with a diameter of less than about 10 microns dispersed substantially evenly through the metal article.
Abstract: Gold, copper, silver, palladium or aluminum and their alloys, but preferably gold or gold alloy, which may be in the form a wire, has deposited thereon or contained within the wire, a material such as metals or metal alloys which diffuse into the gold or into the other listed metals. With the passage of time and exposure to temperature the deposited metal or metal alloy continues to diffuse into the gold forming intermetallics with the gold and thereby causing the resistivity of the gold to increase and causing the gold to become progressively more brittle until such time as the gold wire ruptures at a stress point. At a given temperature the elapsed time until rupture takes place depends upon the metal or metal alloys deposited on or contained within the gold. Lead, indium, gallium, tin, bismuth and aluminum and the alloys of these metals diffuse into and form intermetallics with the gold.

Abstract: A method for regularly and controllably flexing and extending the feet and the legs of a patient who is unable to move their legs and/or feet due to some physical or mental disorder. The oscillating footboard assembly is adjustable and adaptable to the users size. The oscillating footboard assembly is designed to regularly flex and extend (by a controllable amount of excursion and at a controllable frequency) the feet and the legs of a patient who is unable to move their legs and feet due to a physical ailment such as a stroke, coma, or paralysis. If the feet and legs are not regularly flexed and extended, they "freeze" in the extended position and it is extremely difficult and in some instances, impossible to resolve this problem. The frequency and the excursion of the oscillation may be adjustable on the assembly depending upon the needs of the patient. The assembly is easily and comfortably attachable to the patient through the use of booties or other means such as foot straps.
