Apparatus For Making Electrical Coils Using Patterned Dry Resin Coated Sheet Insulation
US Patent:
4095557, Jun 20, 1978
Filed:
May 4, 1976
Appl. No.:
5/683118
Inventors:
Edward J. Croop - Pittsburgh PA
Howard E. Saunders - Pittsburgh PA
Dean C. Westervelt - Acme PA
Howard E. Saunders - Pittsburgh PA
Dean C. Westervelt - Acme PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B05B 502, B05B 1504, B05D 106
US Classification:
118301
Abstract:
A porous, electrical insulating adhesive substrate is made by (A) electrostatically coating a flexible sheet material with heat reactive adhesive resin particles, having an average particle size of between about 1 micron to 2,000 microns, the adhesive particles are applied in a predetermined pattern on the sheet covering from about 10 percent to 90 percent of the sheet material area, the area between the resin pattern not being coated; and then (B) heating the patterned coated sheet material between about 65. degree. C to 250. degree. C, forming a discontinuous, 0. 25 mil to 25 mil (0. 006 mm to 0. 635 mm) thick, dry coating pattern of heat reactive adhesive particles bonded to the sheet material, said heat reactive adhesive coating covering from about 10 percent to 90 percent of the sheet material area; the patterned coated sheet may then be inserted as an oil permeable layer insulation between high voltage windings and low voltage windings and between layers of high and low voltage windings in a wound coil assembly, after which the assembly can be heated at a temperature and for a time effective to securely bond the winding layers together, and thus provide a porous, oil permeable, bonded transformer coil assembly.

Method Of Making Heat Curable Adhesive Coated Insulation For Transformers
US Patent:
4239077, Dec 16, 1980
Filed:
Dec 1, 1978
Appl. No.:
5/965554
Inventors:
George D. Dixon - Monroeville PA
Edward J. Croop - Pittsburgh PA
Edward J. Croop - Pittsburgh PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B05D 306
US Classification:
156272
Abstract:
A flexible resin adhesive coated substrate is made by: (A) coating a sheet material with a wet, heat reactive adhesive resin, containing a monomer and an amount of an ultraviolet radiation sensitive photoinitiator effective to cause polymerization of monomer in response to ultraviolet radiation, and (B) applying ultraviolet radiation to the adhesive resin coating on the sheet material to polymerize monomer without the application of heat, forming a dry, uncured coating of adhesive bonded to the sheet material.
