| X.4430 18.7.23. X.4430 - CAPACITY-TEMPERATURE TESTS OF PAPER CONDENSERS. Of the six condensers experimentally reported in our EFC {E. Fowler Clarke - Electrical Engineer} 1/T13.7.23:- 1. No.494 has been put on H-G.II. 2. Std. condenser No.524 has been returned to production. 3. U.S.A. Bosch condenser marked 774. [handwritten] Steady to rising 4. No.613 - baked at higher temperature, [handwritten] Steady 5. No.32 - Below standard in capacity, [handwritten] Slowly falling 6. No.547 - Standard condenser [handwritten] Falling to slowly falling are still with us, and C.A.P. is going to test the capacity of these about every two days. MADE AT CROXLEY EFC. {E.
