Abstract:

Scroll pumping apparatus includes a first scroll element and a second scroll element; a drive mechanism operatively coupled to the second scroll element for producing orbiting motion of the second scroll element relative to the first scroll element, the drive mechanism having an axis of rotation; and an isolation element to isolate a first volume and a second volume in the scroll pumping apparatus. The isolation element includes a first resilient annular member coupled, directly or indirectly, to the first scroll element, a second resilient annular member coupled, directly or indirectly, to the second scroll element, and a tubular member coupled between the first and second annular members.

International Classification:

B25B001/00

US Classification:

269/016000

Abstract:

A test stand for testing computer hardware components is provided. The test stand has a base structure. A first support arm mounts to the base structure. The first support arm has one or more apertures disposed therein to enable airflow through the support arm to avoid airflow hindrance of cooling fans during operation of the subject internal computer hardware components and when the test stand is in certain positions. A second support arm also mounts to the base structure. The second support arm has a rotation mechanism mounted therein. A support bracket for supporting the test subject computer hardware components extends between the first support arm and the second support arm. The support bracket is in communication with the rotation mechanism, such that the rotation mechanism controls and enables the rotation of the support bracket through a predetermined rotational degree range.

International Classification:

B01D 3300

US Classification:

210359

Abstract:

A filtering device of the piston-cylinder type having a piston (P) and a cylinder (C) with reduced cross-sections (36) and (16) to create a pressurization chamber to force all fluids within the closed end of the cylinder into the piston as the piston is urged toward the closed end of the cylinder.

International Classification:

H01R 1362

US Classification:

439153

Abstract:

A card cage includes upper and lower support members which define a slot for receiving a printed circuit board. An engagement mechanism includes one or more handles pivotally mounted on the front of the card cage. Each handle, in turn, is pivotally attached to a rod which extends to the rear of the card cage and terminates in an extraction member which receives the rear corner of a cirucit board. When the circuit board is mounted in the card cage, the handle is pivoted to contact the forward edge of the board and urge it into position in the cage, thereby urging contacts along the rear edge of the board into engagement with a connector at the rear of the card cage. When the board is to be removed from the card cage, the handle is pivoted in the opposite direction, enabling the extraction member at the rear to pull the board forwardly out of engagement with the connector and permitting the board to then be removed from the card cage.

International Classification:

A61B 17/11

US Classification:

606153

Abstract:

A connector for joining a first hollow structure to the side wall of a second hollow structure, the connector comprising a first component comprising an inner collar; a hollow body; and a graft mounted to the inner collar and forming a conduit through the hollow body and the inner collar; and a second component comprising an outer collar and a hollow body, the hollow body of the second component being sized for coaxial disposition over the hollow body of the first component so that the outer collar of the second component can be adjustably positioned relative to the inner collar of the first component and so that the conduit of the graft provides fluid communication between (i) the region beyond the inner collar, and (ii) the region beyond the hollow body of the first component.
