Indicators for spinning-twisting machine - with single tacho generator and adjustable resistance for spindle speed and delivery speed readings

摘要

The tacho generator measures the spindle speed to deliver a proportional electric signal direct to an indicator to give rpm readings, whilst a junction leads the signal to the adjustable resistance, in the form of a multi-phase rotary potentiometer, to give a signal to the indicator showing the delivery speed in m/min. Device provides a single tacho generator and a cheap resistance to replace the conventional assembly using two expensive generators.
