| Attached to Wd{Mr Wood/Mr Whitehead}/me/8/7/ 13.3.20 Copy of letter received from:- SALFORD ELECTRICAL INSTRUMENTS LTD., METER WORKS, NORTH GEORGE STREET, SALFORD. Your Ref.-Wd{Mr Wood/Mr Whitehead}/Msl2/FJ20.2.20. Our Ref.-HCT/EAC. 26th February,1920. Messrs.Rolls-Royce Ltd., Nightingale Road, D E R B Y. Dear Sirs, re - Condensers. We would confirm our Mr.Turner's visit of the 25th inst. when he demonstrated that your flash test could be used to break down Condensers of your own make which had been previously passed as perfect. It was agreed at this meeting that our Condensers should only be tested in accordance with the specification sheet which had been sent to us, but that the voltage could be raised to 500 at will. We are giving the question of dimensions our best attention, and will supply Condensers such as will fit your case, but we would point out it is extremely difficult to confine Condensers of certain capacity to definite dimensions. As regards building up with Mica, we understand that you have a large number of scrap sheets which you use for the purpose of building up, and we shall be glad to know whether you could let us have some of these sheets. Our Mr.Turner mentioned to you the question of Magnetos which are being made in our Coventry Works, the Conner Magneto and Ignition Co.Ltd., and we are particularly anxious that a Representative of your firm should visit this Works, and see the results they are obtaining. Perhaps some day in the near future this could be arranged, but in the meantime, would you kindly advise us whether the Magnetos you use rotate in clockwise or anti-clockwise direction. Yours faithfully, FOR & ON BEHALF OF SALFORD ELECTRICAL INSTRUMENTS LIMITED. (Sgd.) H.C.Turner. Manager. ENCLOSURE No 45 JUSTSO | ||
