Abstract: A connection includes a first and second surface stationary with respect to one another and a primary seal and secondary seal are formed between the surfaces and a labyrinth redundant seal is formed between the first and second surfaces and intermediate the primary and secondary seals. A connection for sealing against pressure may also include a retainer disposed within a housing receptacle a conduit disposed within a bore of the retainer. A primary seal may be formed between the conduit and the receptacle and a secondary seal may be formed between the retainer and the receptacle. A labyrinth seal may be formed between the retainer and the receptacle and intermediate the primary and secondary seals.

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.
