Patent CA-2295180-C (CA)
Inventor: QUIRK GEORGE
IPC: C23C16/455
Filed: 1998-06-22
Granted: 2003-11-04
Abstract: A gas injection disc is provided which includes an outer ring and a tubular modular insert which slips into the outer ring. The outer ring is provided with an inner bore, a ring-shaped plenum located around the inner bore, an outer gas sealing surface around the plenum, and two gas feed paths extendin g from the periphery of the outer ring to the plenum. The gas feed paths are each provided with a gas feed attachment for coupling gas supply tubes thereto. The insert is provided with a plurality of radially aligned injecta nt holes, an inner gas sealing surface, and an axial bore. The insert is seated in the inner bore of the outer ring such that the inner and outer gas sealin g surface face each other with a small gap provided therebetween which enables the insertion of the insert into the inner bore. The insert thereby substantially encloses the plenum, and the injectant holes are aligned with the plenum to receive injectant gases and direct the injectant gases into th e axial bore of the insert. During the CVD process, the heat generated by the arc jet causes the insert to expand and eliminate the gap between the inner and outer sealing surfaces to thereby prevent undesirable gas leakage. Once the CVD operation is stopped the insert is permitted to cool and contract an d return to its cooleddimensions unencumbered by the outer ring. The insert ma y then be removed for cleaning or for replacement with an insert having different characteristics.

IPC: C02F1/44
Filed: 1995-06-23
Granted: 2005-11-22
Abstract: There is disclosed a system for separating oil and other immiscible contaminants from a liquid body containing the contaminants such as a water body. The system includes the use of a plurality of microporous hollow fibers (16, 18) which may be arranged in any number of arrangements such as bundles, intersecting arrangements, divergent patterns or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communication with a source of suction (28) in order to draw the contaminant via the pores into the fibers for subsequent storage in a suitable container (20, 22). By incorporating acceptable means of density control a substantial amount of the hollow fiber surface area may be exposed to the contaminant thus increasing the extraction efficiency of the contaminant from the water body. The unit optionally may be self-contained. This system provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments.
