    摘要： A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.

    摘要： A headspace insulator for a battery cell operatively coupled to circuitry within an implantable medical device in including one or more of the following: (a) a body of electrically and thermally insulating material disposed between a battery electrode assembly and a battery cover, (b) a receiving area within the body that receives and isolates a battery feedthrough pin, (c) an indentation within the receiving area retaining the feedthrough pin within the receiving area, (d) a raised portion coupled to a battery cover providing an air gap between the cover and the headspace insulator near case-to-cover weld areas, (e) a feedthrough aperture adapted to receive a feedthrough assembly, (f) a pin aperture that receives the feedthrough pin, (g) a fillport aperture for electrolyte fluid flow through the headspace insulator, and (h) a slot that locates a battery weld bracket and isolates it from the feedthrough pin.

    摘要： A reaming tool includes a tubular body having a nose portion with a concave center. A plurality of blades defining junk slots therebetween extend axially behind the nose and taper outwardly from the exterior of the tubular body. Rotationally leading edges of the blades carry a plurality of cutting elements from the axially leading ends. Selected surfaces and edges of the blades bear tungsten carbide, which may comprise crushed tungsten carbide. The shell of the nose is configured to ensure drillout from the centerline thereof toward the side wall of the tubular body. A method of drilling out a reaming tool is also disclosed.

    摘要： A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit. In some embodiments, the waves may be directed into the drill bit from within a longitudinal bore thereof. Reflected waves also may be detected from within the bore. The methods may be used to develop threshold acceptance criteria for classifying drill bits as acceptable or unacceptable to prevent catastrophic failures of drill bits during use. Systems and apparatuses are disclosed for conducting nondestructive ultrasonic inspection of a drill bit used for drilling subterranean formations. The systems and apparatuses may comprise an ultrasonic probe configured for insertion within an internal longitudinal bore of a drill bit. Drill bits are disclosed that are configured to facilitate nondestructive ultrasonic inspection thereof.
