Description : This Syntron (registered trade mark) No. 2 Thermionic Valve is a clear glass bulb with an opening in the top through which a wire lead protrudes. The brass base of the bulb is screwed into a socket that is attached to a pine natural wood stand that was made for the purpose of exhibiting the valve. The inner workings of the bulb appear to be intact. The valve comes with the original brown cardboard box.
Commentaires : This thermionic valve is an early form of a single phase rectifier used to convert A-C current into pulsating D-C current by blocking 1/2 of the sine wave. These valves are recommended for use in the operation of the electromagnetic reciprocating motors of Syntron: electric hammers, electric vibrators, vibrator feeders, vibrating screens, and electric tie-tampers. They are also used for battery chargers, telephone systems, electro-platers, arc welders, sound pictures, magnetic chucks, and other rectifier applications. This is an ancestor of the modern diode and transistor which form an integral part of the modern day computer.
Fonctions : This device, an early form of a single phase rectifier, was used at Consolidated Bathurst Co. Ltd. It was removed from service in 1963.
