Hanbury - Head Complaints} 798. 10-12-20) G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 2947 Contd. -2- EPC2/T25.10.21. that of the Bosch battery ignition, but as pointed out in our note already referred to, the capacity of the Bosch battery ignition per cubic inch is twice as gross as we can get in our mica condensers. The first actual Goshawk condenser shows a the capacity to be approximately as stated above, namely, .13 mf. We are experimentally making up a condenser with paper dielectrics to see if we can obtain a greater capacity in a given space. EPC. | ||
