Abstract: The present application includes a system for generating energy via a rotating drum. The system includes a housing, a drum, and a plurality of enclosed chambers. The housing surrounds the drum and helps to distinguish between a gravitational domain and a buoyancy domain. The drum is coupled to a shaft and configured to rotate within the housing about a central axis. The plurality of enclosed chambers are radially aligned around an internal surface of the drum. The drum is exposed to a gravitational domain and a buoyancy domain simultaneously so as to induce rotation of the drum around the shaft. The enclosed chambers are subjected to gravitational forces in the gravitational domain and the enclosed chambers are subjected to buoyancy forces in the buoyancy domain.

Abstract: The present application includes a method for introducing a hormone directly into an affected area within a tumor. The method includes penetrating the affected area of the tumor with a biopsy needle in order to obtain a biopsy specimen. The specimen is withdrawn along with the biopsy needle. A hormone implant is inserted into the void space left behind as the specimen was removed. The method may also include directly inserting the implant and a treating substance into the tumor without the removal of the biopsy specimen. The implant may have various shapes in order to maximize surface contact. The implant is also configured to have a time release function to regulate dosage delivery.

Abstract: A power generator has a mass that is capable of moving vertically up and down. A generator has a rotor and a stator. A shaft couples the mass to the rotor, with the shaft allowing the mass to move vertically up and down. The shaft has spirals that produce relative rotation between the shaft and the rotor. The mass can float on a body of water that is subject to fluctuating water levels, such as a tidal body or a lock, or the mass can be used on dry land. The mass has an interior cavity. When the cavity contains gas, the mass rises in the water. When the cavity contains water, the mass sinks in the water. When the mass has sunk, gas is introduced into the cavity. When the mass has risen, the gas is vented from the cavity.

Abstract: A tidal power generator has a floating vessel hull that is subject to rising and falling water levels so that the hull moves vertically up and down. Linear-to-rotary converters are coupled between the vessel hull and a fixed object. The converters allow the hull to move vertically while constraining the horizontal movement of the hull. The converters convert the vertical movement of the hull into rotary movement, which is then used to drive an electrical generator. A harborage is provided to protect the hull and the converters and to regulate the water level for the vessel hull as well as become a fixed object relative to the vessel from which a change in relative position causes power to be developed. If the hull is subject to tidal variations, vertical movement of the hull can be desynchronized from the tidal variations so as to store energy during slack tides.

Abstract: An electrically conductive path through an insulating plate (10) is produced by forcing sheets of conductive material (13, 14) into contact through a hole (11) in the plate (10). The sheets (13, 14) are forced together with sufficient force to produce a cold weld junction, which is then plated with a conductive metal (102). Dies for producing the cold weld utilize metallic spheres (110), rods (188) or chemically etched projections (228). Shaped dies (268, 272) form a crimped joint without a cold weld, and offset dies (246, 250) produce a raised junction (252) for use as a mount for a planar component. In manufacturing a printed circuit board (160) the cold weld die (158) is produced with the same drill hole pattern as used to form the drill holes in the printed circuit board (160).A force sufficient to cause metalurgical bonding of the opposed conductors may also be applied by an explosive discharge. A hole in the junction area of the opposed conductors may be created or enlarged by the use of a laser beam.

Abstract: A method for metalizing the surface walls of a printed circuit board through hole to produce an electrically conductive path from one metallic layer of the board through the insulating plate to another metallic layer. A drill bit is forced through the board and into a block of soft conductor material. While the bit is turning the conductive cuttings from the block are carried to the hole in the insulating plate and smeared on the wall surface by the bit. The smeared conductive material creates an electrically conductive path between two metallic layers of the printed circuit board.
