Science: Laytex After Lastex

Not blushing to use the word "revolutionary," U. S. Rubber Co. last week announced Laytex, a new insulation.

Lengths of wire to be insulated are fed vertically through tanks containing the processed milk. At each immersion a film of milk adheres to the wire and dries, any excess falling back into the tank.
