"No buzzer" indicates early problem in electroplating when parts are properly immersed into electropolating bath. Buzzer sounds when current flows through part; however, if current is cut, buzzer stops warning that parts must be removed and refinished thus preventing unnecessary waste of electrical energy and labor.
System, using only one amplifier and operating multiple inputs, eliminates push-to-talk requirement of previous systems and inhibits acoustical feedback by using microphones and headphones.
Circuit determines elapsed operating time for vibrators when three vibrators are located in one room and are powered by two amplifiers through either of two control systems. It operates the control system elapsed time clocks only when voltage is applied to the vibrator armatures.
