| X4630 HS{Lord Ernest Hives - Chair}/Rml/LG. 27th. Feb. 1924. The Cambridge Scientific Instr.Co., Cambridge, England. Dear Sirs, We thank you for your letter of the 25th.inst. ref. WGC/MW., together with record strip. We note your remarks with regard to the electric motor to be used in place of clock-work for the drive. We trust the 12-volt electric motor will be able to be kept within reasonable dimensions so that it will not make the whole instrument too bulky. We suggest that if it were possible to make the record strip of an absorbent paper with a surface on the top to take the record, it would solve the problem of rolling up the strip when wet. Unless we could manage to do this, we are going to experience trouble with 6 ft. or more of paper strip loose in the car. We should like you to consider this point, and also to submit us a quotation for the Chronograph fitted with a 1/10ths. of a second time marker (we do not require seconds as well) and electric motor drive. Yours faithfully. | ||
