[Also in Division H1] In manufacturing capacitors by winding layers of biaxially oriented thermoplastic dielectric such as polystyrene with alternate layers of electrode material and then heating to shrink the plastic, the thickness and relieving force of the plastic are first measured in order that the change of capacitance occurring in the shrinking process may be accurately predicted. The Specification gives figures for heating times and temperatures.
