Mini C-Arm Assembly For Mobile X-Ray Imaging System
US Patent:
5627873, May 6, 1997
Filed:
Aug 4, 1995
Appl. No.:
8/511873
Inventors:
Barry K. Hanover - Salt Lake City UT
David E. Barker - Salt Lake City UT

Assignee:
OEC Medical Systems, Inc. - Salt Lake City UT
International Classification:
H05G 102
US Classification:
378197
Abstract:
A C-arm apparatus. An X-ray imaging system is coupled to a C-arm, including an X-ray source and an image receptor mounted upon opposing locations, respectively on the C-arm. The C-arm is mass balanced about its axis of orbital rotation and is pivotally coupled to an articulating arm assembly supported upon a wheeled support base. The mass balance enables repositioning of the X-ray imaging system between an anterior-posterior view and an orthogonal lateral view with a single, orbital movement of the C-arm which also causes the views to define an imaging isocenter. The C-arm is preferably miniaturized to an approximate diameter of twenty-eight inches with a source-to-image distance of approximately fourteen inches.

Assignee:
Dionex Corporation - Sunnyvale CA
International Classification:
B01L 1100, B01D 1100
US Classification:
422101
Abstract:
An apparatus for receiving chemical compounds carried in a high pressure effluent fluid stream from supercritical fluid extraction. The apparatus includes a heated conduit connected to supercritical fluid extraction device through which an effluent stream flows. The exit port of the heated conduit is located within the airspace of a decompression zone which is free of liquid. A liquid solvent chamber is provided in open communication with the downstream end of the decompression zone into which the effluent stream flows for the recovery of chemical compounds therein.
