Publication number: 20150053669Abstract: Various embodiments of the invention include solutions for chamber-less thermal joining. A first aspect includes a system for performing a thermal joining of a joint space defined by a metallic part without an environmental chamber thereabout. The system may include an induction coil for heating an area adjacent to the joint space defined by the metallic part for the thermal joining of the joint space. The system may also include a gas lens for directing a shielding gas towards the joint space, and a valve system for controlling a flow of the shielding gas from the gas lens. A vacuum system creates a negative pressure in the metallic part to urge the shielding gas through the joint space during the thermal joining, thus allowing thermal joining of the metallic part without an environmental chamber thereabout.Type: ApplicationFiled: August 20, 2013Publication date: February 26, 2015Applicant: General Electric CompanyInventor: Kurt Allen Rakozy

Publication number: 20150022961Abstract: A support component for an apparatus is described. In at least some implementations, a support component is attached to an apparatus (e.g., a computing device) via a hinge mechanism. The support component can serve as a “kickstand” that can be positioned via the hinge mechanism to support the apparatus in a variety of orientations relative to an adjacent surface. In at least some embodiments, a support component includes hinge mounts via which the support component is attached to hinges of an associated apparatus. The support component and associated hinge mounts, for instance, can be manufactured separately and/or via different manufacturing processes, and attached during a production process.Type: ApplicationFiled: July 19, 2013Publication date: January 22, 2015Inventors: Kurt Allen Jenkins, Brett Andrew Tomky, Timothy Jerome Coomes

Publication number: 20150016948Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.Type: ApplicationFiled: August 26, 2011Publication date: January 15, 2015Applicant: TOSHIBA INTERNATIONAL CORPORATIONInventors: Kurt Allen Bihler, David Liu, Mark Douglas Rayner

Publication number: 20140376179Abstract: A surface contact for a support component is described. The support component, for example, can serve as a “kickstand” that can be positioned to support the apparatus in a variety of orientations relative to an adjacent surface. A surface contact disposed on the support component can serve as an interface (e.g., a “foot”) for the support component on the adjacent surface. For instance, the surface contact can be formed from a slip-resistant material such that slippage of the support component on an adjacent surface is reduced or eliminated. In at least some embodiments, the surface contact is embedded with a material that responds to a magnetic field, e.g., a ferromagnetic material. The surface contact is attracted to magnets on an adjacent edge of the attached apparatus, thus stabilizing the support component in a closed position.Type: ApplicationFiled: June 21, 2013Publication date: December 25, 2014Inventors: Kurt Allen Jenkins, Joseph B.
