Appl. No.:

10/179924

Inventors:

Michael T. Mullins - Villa Hills KY
James R. Rodebush - West Chester OH

Assignee:

Tema Systems, Inc. - Cincinnati OH

International Classification:

B01D 3346

US Classification:

210232, 2103601, 210374, 2103803

Abstract:

A horizontal centrifuge has a basket rotatably mounted within a housing. The basket has a plurality of rings disposed between open and closed ends of the basket and a plurality of guide rails circumferentially spaced with respect to the rings. The guide rails have respective lengths extending between the open and the closed ends of the basket and provide a plurality of respective bearing surfaces. A tubular screen is supported in the basket by the plurality of bearing surfaces of the guide rails. A scroll with helical screw flights is also rotatably mounted within the basket. In various aspects of the invention, the tubular screen is made from six arcuate screen segments; the bearing surfaces of the guide rods and the peripheral edges of the helical screw flights are machined surfaces; and the scroll is fabricated.

International Classification:

B04B 1/20
B04B 15/06

US Classification:

494 29, 494 38, 494 53

Abstract:

A clean-in-place decanter centrifuge for processing a combined liquid and solid material to separate the solid material from the liquid. The centrifuge is designed for use in the food processing industry, particularly for dairy products, and therefore has fluid injectors for cleaning all surfaces within the centrifuge including the opposed mating surfaces which function as non-contacting seal mechanisms. The centrifuge has no metal-to-metal contact areas within the interior of the bowl and scroll assembly. In one embodiment, the outer wall of the bowl and scroll assembly comprises a plurality of drain lines located in the rear wall section of the bowl to allow essentially all liquid to drain from the bowl and scroll assembly. In another embodiment, the bowl hub comprises at least one drain line to allow lubrication oil to drain into said cavity and prevent ingress of lubrication oil into said bowl and scroll assembly. In another embodiment, the discharge housing further comprises an enclosure bound by the interior surface of the exterior wall of the discharge housing, partitions within the discharge housing, and the outer wall of the rotating bowl, said partitions being separated from the outer wall of the rotating bowl by non-contacting seals whereby fine solid material that migrates into said enclosure is removable from the discharge housing by liquid sprayed from one or more fluid injectors inserted into said enclosure.

International Classification:

C09G 7102
A61K 3117
A61K 31795
A01N 3300

US Classification:

528367

Abstract:

The narrow poly- or mono-dispersed oligomers of the present invention are polyureas, polycarbonates, polyesters or polyamides having a recurring unit of from 3 to 50. These oligomers are water-soluble, preferably have a rigid backbone, have recurring units coupled by carbonyl linking moieties which have anionic groups, display predominantly linear geometry such that regular spacing between anionic groups exists in an aqueous medium, and are pharmaceutically-acceptable. The narrow poly- or mono-dispersed oligomers are useful for the treatment and/or diagnosis of AIDS and/or ARC or HSV.
