Filed:

Jan 5, 2002

Appl. No.:

10/040875

Inventors:

Rick Morris - San Diego CA, US

International Classification:

B42F013/00

US Classification:

402/073000

Abstract:

A display binder having a spine, a first cover connected to the spine, and a second cover also connected to the spine. A support clip is removably attached to the first cover and the second cover. In a preferred embodiment, the support clip has a first ear and a second ear. The ears function to provide a compressive force to the first cover and second cover, thereby attaching the support clip to the first and second covers. Also, in the preferred embodiment, the support clip is attached to the first and second covers along their bottom edges.

Abstract:

The present invention relates to the field synthetic polymeric microfiltration membrane materials that are fabricated to separate liquids from solids contained therein. One aspect of the invention relates to a sulfone polymer membrane with high surface porosity (high pore density) and distinctive asymmetry that can separate solids (i. e. , blood cells) from a liquid (i. e. , plasma) without the need for centrifugation. The membrane is further rendered hydrophilic through co-casting the sulfone polymer (which is a hydrophobic polymer) with a hydrophilic polymer, such as polyvinylpyrrolidone. Because of these properties and the fact that it requires only a small amount of the solid containing liquid (i. e. , whole blood) to be applied to the larger pore surface, the membranes of the invention are highly useful in testing devices for the quick detection of properties or components contained in liquid samples, such as diagnostic applications (i. e. , the detection of physiological conditions (i. e.
