A cylindrical hollow support sleeve has a degree of flexibility sufficient to allow for the insertion of the conduit at angles less than or equal to an angle normal to the fluid containment wall while maintaining a fluid-tight environment, the hollow sleeve having a first open portion integrally attached to the seal member, the first open portion having a central throughbore in fluid communication with the cylindrical hollow support sleeve, the hollow sleeve having a second open portion opposed to, and integrally attached to the first open portion, the first open portion adapted to flexibly receive the conduit, and the second open portion adapted to releasably hold the conduit in place.

Abstract: A sensor for use in machine wear debris monitoring transducers which detect metallic particles present in a flow of fluid, such as lubricating oil. The sensor comprises an inductive coil having a plurality of turns for surrounding a non-magnetic conduit. An electrically conducting screen is located between the coil and the flow of fluid, the coil being electrically insulated from the screen, so as to isolate capacitatively the contents of the conduit from the coil. The resonant frequency of a tank circuit incorporating the sensor is thus unaffected by changes in the dielectric properties of the contents of the conduit caused by air bubbles and/or water droplets in the flow of fluid. The screen may be a single turn of thin metal foil having a gap between adjacent ends, or a mesh, or a metallic coating sprayed onto the conduit.

Abstract: A method and apparatus for improved attachment of a PCD compact, especially a two-layer disk-type PCD compact, to a tool or support surface with a mechanical connection. In general the PCD compact is provided with a blind bore in the substrate layer, the bore terminating in the substrate layer and opening onto an outer face of the substrate layer intended to engage or abut the tool or support surface. A mechanical fastener is inserted into the blind bore such that it is secured to the PCD compact to form an integral unit with a tool-engaging end of the fastener protruding from the compact. In a preferred form the mechanical fastener is a metal post having at least one, and alternately both, ends threaded for threaded engagement to both the blind bore (which would have its own threads) and suitable threaded openings on the tool.
