International Classification:

G01N 1/34

US Classification:

506 16, 435 34, 435 611, 435 612

Abstract:

The present invention recognizes that diagnosis and prognosis of many conditions can depend on the enrichment of rare cells, especially tumor cells, from a complex fluid sample such as a blood sample. In particular, the present invention is directed to methods and compositions for detecting a non-hematopoietic cell, e.g., a non-hematopoietic tumor cell, in a blood sample via, inter alia, removing red blood cells (RBCs) from a blood sample using a non-centrifugation procedure, removing white blood cells (WBCs) from said blood sample to enrich a non-hematopoietic cell, if any, from said blood sample; and assessing the presence, absence and/or amount of said enriched non-hematopoietic cell.

International Classification:

B63C 900

US Classification:

441 80

Abstract:

An inflatable ice mud water rescue craft has an inflatable closed-loop tube that encircles a floor member and two rescue openings, one inboard at the bow and one inboard at the stern of the craft. Preferably the floor member is inflatable. The tube and floor member form the boundaries for the two rescue openings. The tube turns upward fore and aft of the floor member at an angle in the range of 30 to 65 degrees relative to the plane of the floor member and encircles the rescue openings. The tube and rescue openings at the bow and stern arch more than half as high as the overall beam of the craft above the surface of the rescue scene. Drowning victims or imperiled persons may be brought into the craft through the rescue openings.

Inventors:

George Kriston Walker - Boise ID

International Classification:

A62B 116

US Classification:

182 5

Abstract:

A compact, lightweight, self-contained rappel apparatus by which a person such as a parachuting smoke jumper, aviator, or other person may safely descend a line or rope from a tree canopy or other high perch to the ground or a lower elevation. The invention is designed for one-handed use with a preferred figure 8 system of descent line reeving around and about the top pipe and bottom pipe of the descender that results in multiple frictional line-to-line contact points as the line crosses itself in each figure 8 wrap in the area between the top pipe and bottom pipe.

6/589881

Inventors:

Edward Orlowski - La Mirada CA
George D. Walker - Brea CA

Assignee:

Programmed Composites, Inc. - Brea CA

International Classification:

B29C 3340

US Classification:

264221

Abstract:

A process for forming a hollow, cured composite article. The process includes steps of making a plug from a meltable material. The plug is covered with a polymerizable material and the covered plug is inserted into a cavity formed in a thermally-expansive and heat-resistant polymer held within a rigid container. The almost filled container is covered and the container and part are heated to cause curing of the polymerizable covering. The cured assembly is removed from the thermally-expansive and heat-resistant polymer and heated to an extent sufficient to melt the core.
