| SG{Arthur F. Sidgreaves - MD} MVR RGE By LR{Mr Ellor} / BHC/MJ.16.3.34. Detroit Athletic Club Detroit Sat Mar 3rd '34 Dear HCS, Unfortunately, I did not receive your letters dated Jan 19th & 26th until today, they had been lying here awaiting me all this time, you see I did not stay here when last in Detroit, and even when I arrived on Thurs they were overlooked. I will however deal with points mentioned in your H89/MJ26134 It had occurred to me that since lead bronze bearings are operated at such high temperatures of 275°F - 125°C, and bearings have run satisfactorily at still higher temperatures, that design of oil coolers will be affected, since temperature will be near danger mark with solder, & had therefore arranged to call at Schenectady to see General Electric Co who are specialists in Hydrogen brazing, as something on those lines will be necessary (P.T.O) | ||
