Okay, if you insist.

Mercury Batcher: A very old idea that has been around for at least 50-60 years; certainly nothing new. This device consists of a glass reservoir that contains a large quantity of mercury positioned high above the pump table with little or no support other than the glass arm connecting it to the main manifold body: e.g, if it breaks there will be a large quantity of mercury splattered all over your pump table as well as the floor. (Read: If OSHA found out they would seal off your shop with a very large plastic bag and probably fine you a very large sum of money). There are different methods of "dispensing" the mercury into the tube, but most rely on a solenoid and steel plunger. The solenoid lifts the plunger thereby allowing an (uncontrolled) amount of mercury to drop into the tubulation leading to the unit being processed. When the fill gas is admitted, it is supposed to push the mercury in the tubulation into the just-processed unit. There is no aging of the unit before adding the mercury because the mercury is added before the tube is sealed off, and there is little control over the amount of mercury put into the unit (long tubes may only get a tiny drop and short tubes may get enough for 10 units). Any time saved by the "automatic dispensing" of mercury into the tube is more than off-set by the added time required to make the glass-to-glass seal of the tubulation rather than using the typical compression O-ring seal used in the U.S. And this is just scratching the surface...

As for increasing production, see above for time savings, or lack thereof. With the proper equipment and 1 helper, it is entirely possible to process to completion 14-15 mercury units per hour, pumping two at a time, using reusable mercury traps vs. what a "mercury batcher" is, without question, safely capable of.
