To Order No. Customer's No. S. 19 ordinary battery charging requirements without over-heating the dynamo, although vigorous gassing occurs in the regulating cells. The last proposal was to find the characteristics of the dynamo as a controlled machine, but having the BLIC resistance in its field circuit. Some extra figures are also required to carry some of the curves back to start at zero volts instead of 10 volts as they do at present. Signed HA. This Sheet must be filed on completion of the work. | ||
