| Y6-350 To Sg.{Arthur F. Sidgreaves - MD} HS{Lord Ernest Hives - Chair}/Wst.10/JH.7.4.36. We are sending you herewith a copy of a letter received from the A.C.- Sphinx Sparking Plug Co.Ltd., We are particularly interested in the plugs they are producing with these new sinterkorund insulators,in view of the fact that we feel Mica insulator sparking plugs are nearing the limits in respect to heat capacity and realiability under high duty conditions. We would therefore like to recommend that we support their application for membership of the S.B.A.C. HS{Lord Ernest Hives - Chair}/Wst. | ||
