Abstract: The present invention includes an improved cutting element substrate for cutting elements. The cutting element substrate includes non-planar, non-linear interfaces with an abrasive layer of superhard material affixed thereto often using a high pressure high temperature press apparatus. The cutting element substrate includes a cant intersecting a first and second interfacial surface. A plurality of truncated nodules intersects the first surface and extends towards the second surface. Arcuate segments protrude out of the second surface and are radially positioned along the surface. The truncated nodules are ill-aligned with the arcuate segments proximate the truncated nodules.

Abstract: The present invention includes a hydraulic cartridge and unitary frame connection for a high pressure high temperature press apparatus. The invention includes a hydraulic cartridge and a unitary frame threaded together. The hydraulic cartridge includes a cylindrical base and a truncated hollow conical section with external threads having a taper between about 2.650 and 5.650 inches per foot. The unitary frame defines an inner reaction chamber and has an outer surface. An opening in the unitary frame has internal threads extending axially substantially between the outer surface and the inner reaction chamber. The internal threads are adapted to mate with the hydraulic cartridge and the hydraulic cartridge is attached to the unitary frame along the length of the threads.

Abstract: The invention is a seal system for a coaxial cable and is placed within the coaxial cable and its constituent components. A series of seal stacks including load ring components and elastomeric rings are placed on load bearing members within the coaxial cable sealing 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. The seal system can be used in a variety of downhole components, such as sections of pipe in a drill string, drill collars, heavy weight drill pipe, and jars.

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.
