| 86117 Roy{Sir Henry Royce}/GEA. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.2/MA.23.10.35. CONCORDIA ELECTRIC WIRE CO. THERMO-COUPLE WIRE. We enclose herewith a length of twin core, copper constantan, asbestos, and soft cotton laquered wire supplied by Concordia Ltd. The laquer covering has cracked and become brittle while being in stock. During the making up of thermo couples we have come across breakages in the copper lead example of which we also enclose. It appears that it may have been caused by some corrosive action. Will you please take up the matter with Messrs.Concordia accordingly. Hs{Lord Ernest Hives - Chair}/Wst. | ||
