Title: High pressure gas exchanger
Inventor: SPEARS JAMES R
IPC: C01B5/00
Filed: 1996-06-03
Abstract: An apparatus (10) and method for delivering a high partial pressure of a gas into a liquid. The apparatus has a gas transfer device (12) with a housing (14) that includes upstream (16) and downstream regions, between which there is located a gas-liquid contacting region (20) with contacting members (22), such as hollow microporous fibers. A reservoir (36) of gas supplies the gas at a high pressure (P) to a flask (38) of gas-depleted liquid and to the gas transfer device (12). The reservoir (36) of gas provides hydrostatic pressure for urging the liquid through the contacting members (22) and propelling the gas around the contacting members (32) so that the gas does not diffuse across the contacting members (22). The gas-enriched liquid is then ducted to a high resistance delivery channel (44) for administration to a site of interest without effervescence, bubble formation, or significant disruption of laminar flow.

Title: Two piece diamond deposition mandrel having graphite ring
Inventor: FOYE BRUCE E
IPC: B23P15/28
Filed: 1998-09-25
Abstract: A mandrel for making a free standing diamond includes a TiN coated molybdenum component and a graphite component. In a first embodiment for forming a free-standing diamond film, the molybdenum component has a stepped solid cylindrical shape with a central plateau having a side wall. The graphite ring is provided around the plateau, and has an upper surface which is generally coplanar with the plateau. The diamond film grows across the TiN coated molybdenum component and the graphite ring. According to a preferred aspect of the invention, the graphite ring is affixed about the plateau of the first component by thermal expansion between the molybdenum and the graphite ring during the CVD process. In a second embodiment, a graphite component is provided with a recessed portion which receives a TiN coated molybdenum plug. The graphite component and plug form a generally planar surface. The diamond is coated across the plug and the graphite. In each embodiment, the different coefficients of thermal expansion of the diamond film, the molybdenum, and the graphite, the molybdenum tends to contract under the diamond and separate from the diamond film. The graphite portion has increased diamond adhesion propertiesand causes the diamond to crack in a controlled manner at the boundary of the graphite and TiN coated molybdenum, preventing the film from shattering and resulting in a razor clean break in the diamond film around its perimeter.
