Abstract

788,520. Laminated materials. GENERAL ELECTRIC CO. Aug. 8, 1955 [Aug. 12, 1954], No. 22812/55. Drawings to Specification. Class 140. [Also in Group XXXV] An electrically insulating laminate comprises a layer of paper bonded to a layer of polyethylene terephthalate. Typically, for use as a slot liner in dynamo electric machines, the two laminµ are each 5 mils. thick and are united by a rubber latex-base adhesive, and the paper used is a rag paper.
