| x6113 By/RD. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.3/MA.15.5.33. We have received from the Telegraph Condenser Co.Ltd., a sample of a special impregnated wax having higher dielectric properties and higher melting point than ordinary paraffin wax. In order that we may test this wax out on our condensers and coils we should be glad if you will order for us a small quantity of plain white paper suitable for the standard ignition coil and standard 20/25 & 40/50 condenser. We will then arrange for condenser and coils to be wound with this paper and afterwards impregnated with this special wax for the purpose of comparative tests. Hs{Lord Ernest Hives - Chair}/Wst. | ||
