Abstract: A seal for a coaxial cable electrical connector more specifically an internal seal for a coaxial cable connector placed within a coaxial cable and its constituent components. A coaxial cable connector is in electrical communcation with an inductive transformer and a coaxial cable. The connector is in electrical communication with the outer housing of the inductive transformer. A generally coaxial center conductor, a portion of which could be the coil in the inductive transformer, passes through the connector, is electrically insulated from the connector, and is in electrical communication with the conductive core of the coaxial cable. The electrically insulating material also doubles as a seal to safegaurd against penetration of fluid, thus protecting against shorting out of the electrical connection. The seal is a multi-component seal, which is pre-compressed to a desired pressure rating. The coaxial cable and inductive transformer are disposed within downhole tools to transmit electrical signals between downhole tools within a drill string. The internal coaxial cable connector and its attendant seal can be used in a plurality of downhole tools, such as sections of pipe in a drill string, drill collars, heavy weight drill pipe, and jars.

Abstract: The invention is a seal system for a coaxial cable more specifically an internal seal system placed within the coaxial cable and its constituent components. A series of seal stacks including flexible rigid rings and elastomeric rings are placed on load bearing members within the coaxial cable. The current invention is adapted to seal the annular space between the coaxial cable and an electrical contact passing there through. The coaxial cable is disposed within drilling components to transmit electrical signals between drilling components within a drill string. During oil and gas exploration, a drill string can see a range of pressures and temperatures thus resulting in multiple combinations of temperature and pressure and increasing the difficulty of creating a robust seal for all combinations. The seal system can be used in a plurality of downhole components, such as sections of pipe in a drill string, drill collars, heavy weight drill pipe, and jars.

Abstract: An actively cooled, heat-dissipating module is presented for dissipating thermal energy from a heat producing integrated circuit device. The heat-dissipating module features a tungsten carbide body having high-density fins and a base with an interfacial surface adapted for attachment to an IC device. The base may also be bonded at high-pressure and high-temperature to a sintered polycrystalline diamond buffer element that, in turn, features a metalized interfacial surface suitable for attachment to the device. The high-density fins present a combined surface area at least 20 times greater than the surface area of the interfacial surface of the buffer element or the base of the heat-dissipating module. The tungsten carbide fins are capable of withstanding high flow and high velocity fluid environments. The high surface area of the fins optimizes the convective transfer of thermal energy from the fins to the high flow of cooling fluid. By bonding the module adjacent to the IC device, the number of thermal junctions is reduced, and the efficiency of the junctions is increased.
