  • Patent number: 9356487
    Abstract: A bearing assembly for a rotating shaft uses a carbide sleeve to prevent wear and carry load. The carbide sleeves provide increased life for rotating components used in the severe environments in the oil and gas industries. Various mechanisms can couple the carbide sleeve to the rotating shaft, including keys, keyways, drive rings, reaction rings, and other members to provide particular benefits. These mechanisms allow the carbide sleeve to bear the compressive load of other components, for example, or to slide axially on the shaft, when needed.

  • Publication number: 20070224056
    Abstract: A technique is provided to facilitate pumping of fluids in a well. A submersible pumping system utilizes a submersible motor to power a submersible pump. A motor protector works in cooperation with the submersible motor to protect motor fluid within the submersible motor and to reduce differential pressures between the internal motor fluid and the external well fluid. The motor protector incorporates a piston slidably sealed within an interior cavity of the motor protector for movement to reduce undue differential pressures.

  • Publication number: 20060070031
    Abstract: Strategies are described for organizing the runtime components of an application into an entity domain framework. The entity domain framework includes one or more entity domains arranged in a hierarchical fashion. Each entity domain further groups one or more components together in a hierarchical fashion. Each entity domain can include one or more services that provide a policy to the components within the entity domain. Composite functionality couples the framework together, and further provides a bus-like mechanism whereby an entity can forward service requests up through the hierarchy until a domain is found that satisfies the requests. Exemplary services provided by the entity domain framework include lifetime management services, error handling services, and so forth.

  • Patent number: 5818865
    Abstract: A pre-ionizing system in which the pre-ionizer elements are integral with the cathode insulating plate is provided. The cathode insulating plate includes a recessed region machined into the front surface into which the cathode fits, lying substantially flush with the insulator front surface. The back surface of the insulating plate contains a pair of slots running parallel to the long axis of the cathode. The pre-ionizing rods are located within these slots, the slots having sufficient depth to locate the rods approximately adjacent to the cathode. By maintaining the rods at ground, a capacitor is formed in which the insulating plate material between the rod and the cathode acts as the dielectric material of the capacitor. When a voltage pulse is applied, a capacitive corona discharge is formed which pre-ionizes the gases in the region near the cathode.

  • Patent number: 5770933
    Abstract: A brushless DC motor with an adjustable timing feature is provided. The timing adjustment allows a specific motor's performance to be optimized by compensating for individual variations both in the characteristics of the rotor position sensors as well as in their locations. The rotor position sensors may be affixed to a heat sink within a portion of the motor housing. To improve the cooling efficiency of the heat sink at least a portion of the motor housing to which the heat sink is thermally coupled is cooled through either active or passive cooling. The rotor position sensors may be enclosed by a structure which improves their thermal and electrical isolation. A means of monitoring and controlling the speed of the motor is also provided.
