An automatic flow rate converter

Abstract

The method for conversion of flow rate of carrier in the elementary analysis for the most convenient driving of combustion gas has been investigated and an automatic apparatus for this purpose is presented.
An electromagnetic valve with a regulator for adjusting flow rate in which the converting action is controlled by the input signal (1) and a relay conversion system in which the flow rate is regulated by the output control of variable load and the relay acts on the input signal (2) were compared. The process (2) was more convenient for operation and the least amount of flow was obtained accurately and with ease. Also, it was convenient for making an apparatus very small and compact.
The apparatus by the second system is consisted of a conversion mechanism in which the conversion of flow rate is done by the relayed action of a micro-switch on a mortor-driven cam, a control circuit for adjusting flow rate and an estimation mechanism for indicating flow rate.
The conversion mechanism is composed of a servo-motor with a suitable time period and a nut with special abrasion surface transmitting the rotation of the motor which is contacted with a shaft fixing two cams for determination of time period and conversion.
Since the time period of the cam is variable and available for free selection, the instrument is applicable for various purposes.
