Abstract: A method by which a gold-coated palladium foil, singly or in combination with metal oxides, can be made to permanently remove hydrogen gas from an attached vacuum chamber, either electrically-passive or electrically-active has been discovered. The foil assembly (301) is secured onto a demountable or permanently affixed flange (303), through which hydrogen gas passes via permeation (102), from the vacuum chamber being pumped (401), to atmosphere. Palladium combined with a metal oxide (502), secondary metal layer (503), gold coating (504) and an applied voltage (509) increases the pumping speed. Methods associated with this claim include the foil mounting and sealing, configuring film composition and applying requisite bias voltage.

Abstract: A method by which titania, or other composition, nanotube arrays, grown anodically or otherwise, can be made to meter vacuum pressure through hydrogen absorption has been discovered. The nanotube array (203) is fixed onto a demountable or permanently affixed flange, through which electrical current can be passed. By metering the current (205) for an allowable range of bias voltages (207), a resistance value (302) can be obtained. This resistance is related to the hydrogen pressure (202) through cross-calibration at the overlap with conventional gauges. Conventional gauges require free electrons for ionization of gas molecules, directly contributing to the pressure in the vacuum volume. The present invention avoids that complication by relying on the absorption of hydrogen. The method associated with this embodiment includes the mounting, bias, current measurement, restoration and boosting techniques all compatible with the operation of a vacuum vessel at very high, ultra-high and extreme-high vacuum levels.

Abstract: A photoelectron linear accelerator for producing a low emittance polarized electric beam. The accelerator includes a tube having an inner wall, the inner tube wall being coated by a getter material. A portable, or demountable, cathode plug is mounted within said tube, the surface of said cathode having a semiconductor material formed thereon.

Abstract: A bodyside cover for an absorbent article is disclosed which includes two different materials to provide enhanced functionality. The bicomponent cover includes an apertured first material, which is positioned along the longitudinal central axis of the absorbent article, and a nonperforated second material secured to at least a portion of the first material. The first material has a rewet value which is less than, or equal to, the rewet value of the second material while the second material is softer than the first material. The first material is positioned below the principal point of fluid discharge and represents the primary fluid-receiving region of the cover. The second material is situated away from the principal point of fluid discharge and represents the secondary fluid-receiving region of the cover.

Abstract: A containment and circulating system for drilling fluid is provided having generally circular tank means for receiving drilling fluid from a well during well drilling operations and from which the drilling fluid is withdrawn and injected into the well. The system incorporates a plurality of generally cylindrical tanks having cylindrical side wall means in normal relation with a substantially planar bottom wall. On opposed sides of each circular tank is provided angulated flow directing walls which intersect both the side wall and bottom wall. The flow directing walls receive the radiating flow from the impeller and direct it upwardly along opposed portions of the cylindrical side wall of the tank. An impeller is centrally located at the lower portion of each tank thereby inducing radiating flow of drilling fluid toward the lower outer wall structure of each tank.

Abstract: Apparatus by means of which a plurality of coaxial cables can be connected through a flexible adapter board to a printed circuit mother board, comprising, a rigid metal chassis and means to support a flexible adapter board, by means of screws attaching it to the chassis. On one end of the adapter is a metal bracket having a flat portion parallel to and spaced from the adapter board, to which are fastened a plurality of coaxial cable terminals. The central conductors of each terminal extends as pins to and through selected holes in the adapter, and are soldered to the metal conductors on the surface of the PCB adapter. At the second end of the adapter is a male terminal, which is adapted, to be inserted into and connect with a printed circuit board receptacle, positioned on the mother board, which is conventionally fastened removably to the chassis.
