International Classification:

B32B 516
B32B 2708
B32B 2900

US Classification:

428323

Abstract:

The use of a fully-hydrolyzed polyvinyl alcohol modified melamine-formaldehyde resin coating containing finely divided metallic powder in a decorative laminate eliminates the necessity for thin metallic foils without thereby imparting any deleterious effects to the laminate itself.

B32B 516
B32B 2708
B32B 2904

US Classification:

428204

Abstract:

Incorporating abrasive materials into the resin impregnated print sheet and thereafter applying a coating of a fully hydrolyzed polyvinyl alcohol modified melamine-formaldehyde resin results in an effective abrasion-resistant decorative laminate which eliminates the necessity for an overlay sheet containing abrasive materials and cellulosic fibers.

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

F28B 910
F28B 908

US Classification:

165111

Abstract:

A fuel vapor recovery device having: a condenser in communication with fuel vapor from a fuel tank, the condenser condenses fuel from the fuel vapor; a reservoir collecting condensate from the condenser, the reservoir maintains the condensate at a temperature sufficient to maintain the condensate in a liquid state; and return means returning the condensate to the fuel tank. Also disclosed is a method of removing fuel from a fuel vapor including the steps of: passing the fuel vapor from a fuel tank through a condenser; condensing the fuel from the vapor; cooling the condensate to a temperature sufficient to maintain the condensate in a liquid state; and returning the condensate to a fuel tank periodically.

Assignee:

The B. F. Goodrich Company - Akron OH

International Classification:

D03D 300

US Classification:

428225

Abstract:

Plastic compositions having good sonar transmission, that is low loss of sound transmission, are a composite of a low loss sonar material, for example polyethylene, and a high tensile strength material, for example fiberglass, adhered together by a binder, for example an epoxy. The composite generally has a tensile strength of greater than 100,000 PSI. The composites unexpectantly have a lower sound level loss than would be expected based upon a linear proportion of the amount of high flexural strength material contained therein.

H01L 2148
H01L 2150

US Classification:

438119

Abstract:

There is disclosed herein a method for adhering metallizations to a substrate, comprising the steps of: (1) providing a substrate having a first surface; (2) applying a coating atop the first surface, such that the coating has a second surface bonded to the first surface, and a third surface generally conforming with the second surface; (3) etching away material from the third surface, so as to roughen and form pits in the third surface; and (4) attaching a metallization to the pits in the third surface by plating, sputtering, or similar means.
