This company has produced many millions of these condensers for use in both  alternating and direct current circuits with very satisfactory results. .... capacitors which are about 40 % smaller than the paper and foil type and which could be produced at 20% reduction in cost ... ; The metalized paper condenser heals automatically (known as MP technique, AOB) .. ; The metallized paper condenser uses kraft paper .... ; The condensers as produced by the Bosch Company are of the extended foil type ... ; Recoomendation A company who contemplate undertaking the manufacture of metallized paper ... note An effort is being made to have the metal vaporizing machine removed from The Bosch Plant (regarding it thus being a Trophy of War, AOB) and delivered to Signal Corps Radio Laboratories, Fort Monmouth, N.J.
