Patent number: 7477055Abstract: A system and method for connecting superconducting magnet coils made up of coil segments to allow an integrated winding concept. The integrated winding concept can include serially connecting coil segments of coil pairs in an alternating pattern, which causes coil pairs to be electrically symmetric.

Patent number: 6843306Abstract: Heat is removed from an equipment enclosure using a recirculating air flow loop that is confined entirely within the enclosure. A segment of the air flow loop is directed onto heat-generating components, contained within housings mounted inside the enclosure. A segment of the air flow loop carries heated air to a heat exchanger, which transfers heat to flowing liquid. A portion of the air flow loop traverses through the ductless air volume confined between the housings and inner walls of the enclosure. Blowers to drive the air flow are typically mounted within or on a housing. Heat exchangers are also typically mounted on a housing. Embodiments of the present invention enable a single heat exchanger or multiple heat exchangers to cool multiple electronic components without complicated ducting and without exhausting heated air into a controlled manufacturing environment, e.g. a clean room.Type: GrantFiled: July 27, 1998Date of Patent: January 18, 2005Assignee: Cymer, Inc.Inventor: Paul S.

Patent number: 6694602Abstract: A method is presented for manufacturing laminate tile metal pole pieces for an MRI. Each laminate tile has a trapezoidal or annular sector shape. The trapezoidal shape allows the tiles to be attached side by side to form a multiple concentric annular array pole piece without using oddly shaped edge filler tiles needed to fill a circular pole piece with square tiles. The pole piece is made by placing a plurality of tiles into a mold and filling the mold with an adhesive substance to bind the plurality of tiles into a unitary tile body. The unitary tile body is then removed from the mold and attached to a pole piece base to form the pole piece. The mold cavity surface preferably has a non-uniform contour. The bottom surface of the unitary tile body forms a substantially inverse contour of the mold cavity surface contour.Type: GrantFiled: December 18, 2000Date of Patent: February 24, 2004Assignee: General Electric CompanyInventors: Evangelos T. Laskaris, William D. Barber, Bulent Aksel, Paul S. Thompson, Michele D. Ogle
