ABSTRACT:
A mercury doser for automatically and accurately dosing arc tubes at high production rates comprises a rotatable stainless steel metering plate sandwiched between tetrafluoroethylene discs. The plate contains a graduated series of metering cavities of which one is selected. Mercury is fed by gravity into the selected cavity at a loading position where any trapped air or gas escapes through a vent port. The port is so small that surface tension prevents entry of the mercury. The plate is then advanced to an unloading position where a puff of argon gas expels the mercury charge into a delivery channel.
