Appl. No.:

11/807391

International Classification:

H01R 4/60

US Classification:

439196, 439387, 174 156, 310 79

Abstract:

In one embodiment the present invention is a Flexible Connector Assemblies (FCA) that comprises top and bottom plates connected by Flexible Connectors (FC) and provides a compliant electrical joint between the first terminal lead and the second terminal lead. These terminal leads and are connected to the top and bottom plates eccentrically in such a way that the total current through the FCA is more evenly distributed among the FC than when the leads are centered on their respective plates. This improvement in uniformity reduces the maximum current carried by any one FC, which substantially extends the operating life of the component.

Abstract:

A coil system for inductively heating a superconducting magnet in order to provide an internal energy dump by uniformly quenching a high performance superconducting magnet. The quench-inducing system uses AC magnetic fields that require negligible reactive power. The system is especially suited for inducing a relatively uniform quench in dry superconducting magnets.

International Classification:

F16K 31/44

US Classification:

251279000

Abstract:

A valve assembly including a first plate having a first surface defining a port, a second plate received over the first plate such that the port of the first plate is substantially closed by a first surface of the second plate, wherein the second plate is movable away from the first plate to open the port, and a fixed member spaced from a second surface of the second plate, the second surface facing away from the first surface of the second plate. A first linkage has opposing first and second ends, and the first end is positioned adjacent the second surface of the second plate, and a second linkage has opposing first and second ends, and the first end is pivotally connected to the second end of the first linkage and the second end of the second linkage is positioned adjacent the fixed member.

International Classification:

G01F001/68

US Classification:

732025, 7320421

Abstract:

A sensing apparatus for use in a mass flow rate sensor for measuring a fluid flow rate includes a main conduit for containing a fluid flow, and a capillary tube for tapping a portion of the fluid flow from the main conduit at a first location, and returning the portion of the fluid flow to the conduit at a second location. The capillary tube is disposed about a centerline, and includes an inner wall defined by an inside radius measured from the centerline. The inside radius varies periodically, preferably sinusoidally, along the centerline for at least a portion of the capillary tube, thereby forming a turbulated surface on the inner wall. The turbulated inner wall increases wall surface area, and fluid mixing. The resulting increased heat transfer rate decreases the error in sensor output from nonlinear behavior.
