Filed:

Jun 9, 2000

Appl. No.:

09/590677

Inventors:

Henry P. Offer - Los Gatos CA
Siamak Bourbour - San Jose CA
William F. Bowen - Santa Cruz CA
Bryan K. Chavez - San Jose CA
Ron B. Ninomiya - San Jose CA

Assignee:

General Electric Company - Schenectady NY

International Classification:

B23K 900

US Classification:

219 72

Abstract:

An underwater exclusion device includes a housing for a welding torch having leading and trailing arrays of pivotal fingers for engaging in grooves along a work surface to exclude water from an exclusion area within the housing containing the welding torch. The fingers are pivotally mounted and independently and individually movable under the bias of springs between retracted and extended positions. The fingers have radiussed distal ends for engaging the work surface. Upon application of the device to the work surface, the leading and trailing arrays of fingers are displaced under spring pressure to engage their distal ends against the work surface, excluding water from within the housing. The side walls of the housing carry seals for seating along the work surface to prevent water incursion in gaps between the side walls and the work surface.

International Classification:

B23K 900

US Classification:

219 72, 405 12

Abstract:

A housing for an underwater processing device, for example, welding, includes a welding head movable laterally relative to the housing and the direction of the weld. At opposite ends, gates are provided having arcuate convex surfaces forming edge seals for engaging in the groove of the work surface. In one form, the gates are linearly slidable and biased in a direction away from the housing. In another form, the gates are pivotally mounted for engaging in the grooves. In both cases, the compliant seal about the margin of the housing, together with the arcuate seal of the gates, maintains a substantially water-free area within the housing to enable processing.

Abstract:

This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.

Abstract:

Systems and methods for removing lipids from a fluid, such as plasma, or from lipid-containing organisms. A fluid is combined with at least one extraction solvent, which causes the lipids to separate from the fluid or from lipid-containing organisms. The separated lipids are removed from the fluid. The extraction solvent is removed from the fluid or at least reduced to an acceptable concentration enabling the delipidated fluid to be administered to a patient without the patient experiencing undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid, to a different patient, or stored for later use.
