摘要： A method for regeneration of a CDPF disposed in the exhaust stream of a diesel engine. The method includes a second phase operation following a first phase substantially as disclosed in the prior art. As the first phase ends, as indicated by a temperature sensor at the exit end of the CDPF, the temperature and oxygen content of the exhaust gas are increased at the entrance to the CDPF in an ensuing second stage. These increases cause oxidation of the soot remaining near the entrance and the sides of the CDPF, resulting in a cleaner and higher-capacity CDPF than is produced by a single-phase regeneration in the prior art. The sequential stages are implemented via an algorithm programmed into an Engine Control Module (ECM). A CDPF regenerated in accordance with the invention can have approximately 95% of its filtration capacity restored.

摘要： A rotary-type earth-boring drag bit with cutters oriented at varied rake angles and methods for designing such drag bits. Specifically, cutters that are located sequentially adjacent radial distances from a longitudinal axis of the drill bit have cutting faces that are oriented at rake angles that differ from one another. These cutters may be located on the same blade of the drag bit or on different blades of the drag bit. The rake angles at which the cutting faces of these cutters are oriented may be based, at least in part, on the relative radial distances these cutters are spaced from the longitudinal axis of the drag bit, on the vertical positions of these cutters along the longitudinal axis of the drag bit, or in response to actual or simulated evaluations of the use of the drag bit to drill a subterranean formation.

摘要： An earth-boring bit has a bit body and at least one bearing shaft depending inwardly and downwardly from the bit body. The bearing shaft has a base and a generally cylindrical bearing surface and at least one cutter is mounted for rotation on the bearing shaft. A bearing seal recess is formed generally at the base of the bearing shaft and defines a cylindrical seal face radially recessed from the journal bearing surface. A cutter seal recess is formed in the cutter generally opposite the bearing seal recess and defines a bearing cylindrical seal face. The cutter and bearing seal recesses define a seal gland including a pair of opposed radial seal surfaces. A resilient seal ring is disposed in the seal gland and compressed between the cylindrical seal faces.

摘要： A tri-cone earth-boring bit has nozzles oriented for improved cone cleaning, bottom cleaning and cuttings evacuation. Each of the nozzles is oriented to discharge across a trailing side of a cone at a point considerably inboard of the borehole wall. Each nozzle has an outlet located radially outward from the bit axis a distance that is at least equal to a distance from a top dead center of the heel row of each of the cones to the bit axis. Also, each of the nozzles is oriented to discharge drilling fluid along a line that contacts the borehole bottom at a distance that is no greater than a distance from a bottom dead center of an outermost of the inner rows of the cone to the bit axis. A portion of the drilling fluid discharged from each nozzle will pass by more than one of the rows of the cones.

摘要： An improved electroplating bath, complexing agent, product and method for producing nickel-rich nickel-iron alloys, such as Permalloy, having about 22% iron and 78% nickel. The improved electroplating bath contains a small amount of an organic amine complexing agent such as ethylenediamine or diethylenetriamine which increases the nickel/iron mass ratio of the deposit, causes nickel to be deposited in favor of iron, reduces the sensitivity of the deposit composition to the iron content of the bath and the applied current density. Further, the pH of the bath is adjusted to about 5.0 to stabilize the complexes and tartaric acid is added to complex ferric ion and thus prevent its precipitation. The organic amine complexing agents useful in accordance with the present invention are agents which complex with nickel and include ethylenediamine and diethylenetriamine each having at least two amine groups with each of the amine groups separated by two carbons.
