Patent number: 8684096Abstract: Anchor assemblies for installation within an existing conduit. The anchor assemblies have a nondeformable mandrel, an expandable metal sleeve, and a swage. The expandable metal sleeve is carried on the outer surface of the mandrel. The swage is supported for axial movement across the mandrel outer surface from a first position axially proximate to the sleeve to a second position under the sleeve. The movement of the swage from the first position to the second position expands the sleeve radially outward into contact with the existing conduit.Type: GrantFiled: November 19, 2009Date of Patent: April 1, 2014Assignee: Key Energy Services, LLCInventors: Michael J. Harris, Martin Alfred Stulberg

Publication number: 20140070710Abstract: The present disclosure relates to a lighting component with multiple DC-DC converters. Each of the DC-DC converters is used to independently drive a corresponding string of LEDs. In general, rectifier circuitry receives an AC power signal and generates a rectified signal, which is provided to first and second converter circuitries. The first converter circuitry converts the rectified signal into a first drive voltage for a first string of LEDs and provides a first drive current for the first string of LEDs based on a first drive current control signal. Similarly, the second converter circuitry converts the rectified signal into a second drive voltage for a second string of LEDs and provides a second drive current for the second string of LEDs based on a second drive current control signal.Type: ApplicationFiled: September 7, 2012Publication date: March 13, 2014Applicant: CREE, INC.Inventor: Michael J.

Publication number: 20140001972Abstract: The present disclosure relates to a modular lighting system that may include a driver module, an array of LEDs that are driven by the driver module, and a control module. The control module is configured to control the driver module, which in turn drives the LEDs of the array of LEDs in a desired fashion. The control module may communicate with one or more remote lighting control systems through wired or wireless communications and function to control the driver module accordingly. Notably, the driver module and the control module communicate with each other through a standard communication protocol, such that either of the driver module or the control module can be replaced without replacing the other of the driver module or control module. Further, power may be provided to the control module and the array of LEDs by the driver module via the standard communication interface or separate power interface.Type: ApplicationFiled: August 20, 2012Publication date: January 2, 2014Applicant: CREE, INC.Inventors: Michael J.

Publication number: 20140001962Abstract: The present disclosure relates to a modular lighting system that may include a driver module, an array of LEDs that are driven by the driver module, and one or more auxiliary modules. The auxiliary modules are configured to control the driver module, which in turn drives the LEDs of the array of LEDs in a desired fashion. The auxiliary module may provide a bridge for communications with one or more remote lighting control systems through wired or wireless communications and function to control the driver module accordingly. Other exemplary auxiliary modules may include modules that function to control the driver module based on one or more of ambient light, ambient temperature, room occupancy, emergency lighting requirements, and the like.Type: ApplicationFiled: August 20, 2012Publication date: January 2, 2014Applicant: CREE, INC.Inventor: Michael J.

Patent number: 8453729Abstract: Novel hydraulic actuators and hydraulic setting assemblies are provided for use in downhole, oil and gas well tools. The novel hydraulic actuators include a cylindrical mandrel and an annular stationary sealing member connected to the mandrel. A hydraulic cylinder is slidably supported on the mandrel and stationary sealing member and is releasably fixed in position on the mandrel. The stationary sealing member divides the interior of the cylinder into a bottom hydraulic chamber and a top hydraulic chamber. An inlet port provides fluid communication into the bottom hydraulic chamber, and an outlet port provides fluid communication into the top hydraulic chamber. A balance piston is slidably supported within the top hydraulic chamber of the actuator. The piston includes an axially extending passageway. Fluid communication through the piston and between its upper and lower sides is controlled by a normally shut valve in the passageway.Type: GrantFiled: February 4, 2010Date of Patent: June 4, 2013Assignee: Key Energy Services, LLCInventors: Michael J.

Patent number: 4636249Abstract: The invention is directed to a method of and apparatus for, introducing into a bath of molten metal (e.g. ferrous metal) contained in a vessel an alloying component (e.g. lead) or a reagent. The method includes the steps of connecting a plurality of plugs or nozzles located in the bottom and/or sides of the vessel to supplies of gas (e.g. argon) under pressure, and causing gas to be introduced simultaneously through the plugs or nozzles to produce individual gas flows which pass upwardly through the metal bath to create areas of turbulence on the bath surface. The areas of turbulence interact to produce on the bath surface a relatively quiescent region and it is into this relatively quiescent region that the required quantity of alloying component or reagent is added.Type: GrantFiled: December 23, 1985Date of Patent: January 13, 1987Assignee: British Steel CorporationInventors: Arthur Laycock, Michael J.
