US Patent:

39621537, Jun 8, 1976

Filed:

Jun 14, 1973

Appl. No.:

5/369814

Inventors:

Robert Walton Gore - Newark DE

Assignee:

W. L. Gore & Associates, Inc. - Newark DE

International Classification:

C08J 900
B29D 2700

US Classification:

260 25R

Abstract:

This invention provides a tetrafluoroethylene polymer in a porous form which has an amorphous content exceeding about 5% and which has a micro-structure characterized by nodes interconnected by fibrils. The material has high porosity and high strength. It can be used to produce all kinds of shaped articles such as films, tubes, rods, and continuous filaments. Laminations can be employed and impregnation and bonding can readily be used to produce a large variety of articles. Compressed articles of very high strength can also be produced from these porous forms.

International Classification:

A41B 1700
A41D 304
B32B 2740
B32B 2728

US Classification:

428315

Abstract:

A waterproof article for use in, for example, protective clothing. The article prevents liquid water from penetrating through to undergarments while at the same time permitting moisture vapor such as perspiration to pass out through the article. The article is thus both breathable and waterproof. The article is layered: a microporous hydrophobic outer layer which permits the passage of moisture vapor but resists penetration by liquid water at pressures up to about 345 Kn/m. sup. 2 ; a hyrophilic inner layer permitting the transfer of moisture vapor but preventing surface tension lowering agents such as those contained in perspiration and/or body oils from reaching the hydrophobic layer.

US Classification:

524515

Abstract:

An elastomer composition, including: at least one elastomer; a plasticizer which includes at least one polymeric material having a weighted average molecular weight of (Mw) of 500 to 1,000,000, formed from at least one ethylenically unsaturated monomer, and a curing agent, wherein the at least one polymeric material is substantially permanent within the elastomer. The subject elastomer compositions have enhanced plasticity and processability without attendant migration, heat or solvent extraction and compatibility problems.

Appl. No.:

7/263931

Inventors:

Robert W. Gore - Newark DE

Assignee:

W. L. Gore & Associates, Inc. - Newark DE

International Classification:

G01M 326

US Classification:

73 76

Abstract:

A method and apparatus for testing wearing apparel that defines an enclosure for moisture vapor transmission. Thin, flexible, waterproof liners which have a high permeability to moisture vapor are inserted into the interior of the apparel and filled with water. The water may be heated to simulate body temperatures and to produce higher concentrations of moisture vapor inside the apparel article. The amount of moisture transferred to the external environment of the apparel article, as well as the amount of moisture absorbed and condensed in the apparel article itself, can be measured by the weight differences which occur over a test period. The method is non-destructive and suitable for quality control, as well as for new product design.

International Classification:

B01D 300
C02F 104

US Classification:

203 10

Abstract:

A membrane distillation module is provided with a thin, flexible microporous membrane positioned against an impermeable condensor sheet that is stiffer in bending than the membrane. Distillate vapor diffuses through the membrane from the hot feed flowing rapidly past the membrane, and condenses and collects between, and in intimate contact with, the membrane and the condensor sheet. The condensed distillate is stripped by forces exerted by the hot feed acting on the distillate across the membrane, and flows toward a distillate outlet located in the downstream direction of the hot feed flow. Cold feed flows past the condensor sheet in the counter direction to that of the hot feed for absorbing the latent heat of condensation, and is subsequently additionally heated and introduced into the hot feed channel. Expanded microporous polytetrafluoroethylene (PTFE) is the preferred membrane material, and a spiral-wound assembly is the preferred configuration.
