Abstract

In the case of transfering the angle on the sextant to the other instrument such as three arm protractor, we used to read the graduation first then transfer it to the instrument. I devised to transfer the angle by using a sychro-motor, electric transfering apparatus, without reading the graduation. One of the aims of this apparatus is to connect it with "course-recording apparatus of the coasting", explained on this book. Fig.1 is the sextant connecting with a sending synchro-motor. Fig.2 is the wiring figure of a synchro-motor. Fig.3 is the connecting apparatus of the receiving svnchro-motor and gear.
