Abstract: An impact borer, a connector, a method for embedding lines and an improved method for sinking geothermal wells. The impact borer has a shell, which has a longitudinal bore. An anvil closes one end of the bore. A ram is reciprocally slideable within the bore, against and away from the anvil. The ram divides the bore into front, rear, and ram chambers. A director is joined to the shell. The director is monolithic. The director isolates the front and rear chambers in alternation upon reciprocation of the ram. The director defines an inlet passage communicating with the ram chamber and an outlet passage communicating with the rear chamber.

Abstract: A method of isotope enrichment including providing a reactant. The reactant is a mixture of at least two isotopic compounds. One of the isotopic compounds has a greater percentage of a selected isotope than the other. An electron transfer agent is introduced into the reactant isotopic mixture to form a reaction mixture. The electron transfer agent facilitates transfer of electrons interactive with one or more selected nuclei of the reactant. The electron transfer agent is in an amount sufficient upon reaction of the reaction mixture to establish an equilibrium between an electron rich reaction product and an electron poor reaction product. The reaction mixture is reacted until the equilibrium is established. The electron poor reaction product is then separated from the electron rich reaction product.

Abstract: A tool driver comprising a shaft, a shank, a flange, a clamp and a retainer. The shaft has a longitudinal axis and opposed ends. The shank is joined to one end of the shaft. The flange is joined to the other end of the shaft and has an outwardly facing flange surface extending from the shaft transversely of the axis. The clamp has a clamping surface facing the flange surface. The clamp is movable axially relative to the flange to vary the separation of the surfaces. The retainer is operatively connected to the clamp and is movable relative to the clamp between a first position and a second position. The retainer, in the first position, precludes relative movement of the clamp and the flange.

Abstract: A tool driver having a body with a longitudinal axis and opposite ends. A boss is positioned at one of the ends. A tool collet is positioned at the other of the ends. A plunger is positioned within a bore in the body. The body has a pair of oppositely disposed pins, at least one of the pins being movable in relation to said body in response to movement of the plunger. An actuator is positioned on and connected to the plunger. The actuator and plunger move as a unit axially of said body between an at rest position and a static position. One pin is movable between an extended position and a retracted position as the plunger and actuator move between an at rest position and a static position, whereby a tool can be positioned on the tool driver when the plunger and actuator are in their static position and held in operable position on the tool driver when the plunger and actuator are in their at rest position.

Abstract: A package comprising a sheet of self-supporting material. The sheet has at least one opening therein. The opening is spaced from the edges of the sheet and is filled with a plug. In specific embodiments, the plug may be of a permeable material to which an item such as an electronic component may be adhered by its pins or may be adhered or the plug may be the item to be shipped itself.
