Abstract: A roller cone drill bit is disclosed which includes a bit body adapted to be coupled to a drill string. A bearing journal depends from the bit body. A single roller cone is rotatably attached to the bearing journal. The roller cone has a plurality of inserts disposed at selected positions about the cone. The journal defines a rotation angle with respect to an axis of rotation of the bit such that the roller cone includes a wall contact zone and a bottom contact zone. At least one of the inserts disposed in the wall contact zone has an extension portion terminating in a substantially planar upper surface.

Abstract: A rotary rock bit includes a lubricant reservoir with a pressure compensation assembly disposed therein. The pressure compensation assembly is adapted to permit selective adjustment of the relief pressure set by the assembly through the selective adjustment of one member in the assembly with respect to another member in the assembly.

Abstract: A drill bit, comprising a bit body, a sensor disposed in the bit body, a single journal removably mounted to the bit body, and a roller cone rotatably mounted to the single journal.

Abstract: A roller cone drill bit is disclosed which includes a bit body adapted to be coupled to a drill string, a bearing journal depending from the bit body and a single roller cone rotatably attached to the journal. The roller cone has a plurality of inserts disposed thereon. In one aspect, the inserts have an extension length of at least 0.6 inches. A roller cone drill bit is disclosed, including a bit body, a bearing journal depending from the bit body, and a single roller cone rotatably attached to the journal. The roller cone has a plurality of inserts disposed thereon. In another aspect, the inserts are arranged such that at most about 20 percent of the inserts are crossed substantially at centerlines thereof by any single plane which contains the axis of the cone axis 10 and which crosses at least two of the inserts.

Abstract: The invention relates to polypeptides that are sperm-specific forms of the catalytic subunit of cAMP-dependent protein kinases, referred to herein as “Cs polypeptides,” nucleic acid molecules encoding Cs polypeptides, and uses thereof. Cs is found in sperm cells and is related to the cAMP dependent protein kinase C&agr;1.
