Publication number: 20140319994Abstract: An exemplary ion source for creating a stream of ions has a chamber body that at least partially bounds an ionization region of the arc chamber. The arc chamber body is used with a hot filament arc chamber housing that either directly or indirectly heats a cathode to sufficient temperature to cause electrons to stream through the ionization region of the arc chamber. Electrically insulating seal element(s) engaging an outer surface of the arc chamber body are provided for impeding material from exiting the chamber interior openings of the arc chamber body. The seal element(s) have a ceramic body that includes an outer wall that abuts the arc chamber body along a circumferential outer lip. The seal also has one or more radially inner channels bounded by one or more inner walls spaced inwardly from the outer wall. The electrically insulating seal element comprises a Boron Nitride (BN) material.Type: ApplicationFiled: April 25, 2013Publication date: October 30, 2014Inventors: Neil K. Colvin, Tseh Jen Hsieh

Patent number: 8851194Abstract: A seal assembly between a wellhead housing having a bore and a casing hanger, has an inner seal leg for sealing against hanger and an outer seal leg for sealing against housing. An extension extends downward from outer seal leg and has a downward facing shoulder that rests on an upward facing shoulder formed on a nose ring. Connection connects seal ring to the nose ring with a lower portion of the nose ring resting on the upward facing shoulder of the casing hanger. Bellows are formed on the nose ring to increase lockdown capacity. Bellows have an inner surface that faces an outer profile of the hanger, and an outer surface on the bellow that faces the bore of the housing. When the bellows are axially collapsed, they expand radially outward and contract radially inward into the bore of the housing and the outer profile of the hanger.Type: GrantFiled: May 24, 2011Date of Patent: October 7, 2014Inventors: David L. Ford, Daniel C. Benson, Leonard Landriault

Publication number: 20140260015Abstract: A tubular passage for poured concrete decks has an intumescent tube held in a two-part, clamshell base by a bottom clip. A first tube engages the base's top to clamp a funnel shaped, diaphragm seal to the base. The first tube has spaced, radially extending, parallel ridges at predetermined distances from the base. Longitudinal channels separate the ridges. An extension tube has inward extending lugs passing along the channels to engage various ridges when rotated to fix the passage length. The extension engages the base bottom for corrugated deck supports. A cap with repositionable, locating filaments closes either tube.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventors: Timothy M. McConnell, Virgil O'Neil, Larry D. Brown, Dennis L. Hart

Publication number: 20140270221Abstract: A wall separates a first volume from a second volume and has a hole allowing passage between the first volume and the second volume. A wire passes through the hole, and a gasket surrounds the wire at the hole. The gasket includes a first section including a groove between a first flange and a second flange, the groove has an outer diameter matched to the diameter of the hole and the flanges have outer diameters greater than the diameter of the hole. A second section adjacent the first flange includes a tubular portion having a diameter less than the diameter of the hole and a tapered section smoothly transitioning from the diameter of the tubular portion to the diameter of the first flange. The gasket prevents flow of fluid through the hole between the first volume and the second volume.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Tristan Edward Taylor, Aaron Michael Reich

Patent number: 8814173Abstract: A seal for stemming leakage flows between adjacent components, especially of a gas turbine, has an elastically deformable, thin-walled sealing element and a thin-walled cover element which is U-shaped in cross section and between its legs and its base partially accommodates the sealing element. The legs of the cover element are arranged in the sealing arrangement, which features the seal, between two oppositely disposed walls of the other component in a movable manner relative to these walls which, together with the sealing surface of the other component, form a groove which is U-shaped in cross section. Forces, which act laterally upon the seal, are absorbed by the cover element and via the legs are diverted into the other component so that the integrity of the seal is maintained even in the case of lateral forces.Type: GrantFiled: December 27, 2010Date of Patent: August 26, 2014Assignee: Alstom Technology LtdInventors: Thorsten Motzkus, Urs Benz
