How does a mercury rectifier work at low pressure?
Operation of the rectifier relies on an electrical arc discharge between electrodes in a sealed envelope containing mercury vapor at very low pressure. A pool of liquid mercury acts as a self-renewing cathode that does not deteriorate with time.
Why is a large envelope required for a mercury arc valve?
The large size of the envelope is required due to the low thermal conductivity of glass. Mercury vapor in the upper part of the envelope must dissipate heat through the glass envelope in order to condense and return to the cathode pool. Some glass tubes were immersed in an oil bath to better control the temperature.
Where is the mercury rectifier on display in Switzerland?
Mercury rectifier on display in the Beromünster AM transmitter in Switzerland, before being decommissioned. Three-phase full-wave rectifier with six anodes.
What kind of MRU is used for mercury removal?
A non-regenerative MRU is sulphur impregnated on carbon or metal sulphide beds. The common and traditional approach to mercury removal has been through the use of sulphur impregnated carbon beds.

What should the temperature be on a 2.5 liter Mercury outboard?
Note: Temperatures for Merc. outboards should be in the 140-160 degree range. All 2 liter, 2.4 liter, and 2.5 liter gearcases interchange. They won’t interchange onto a 3 liter or the old 3.4 liter, both of which are unique to their size engine. (4)
How does the bottem end work on a Mercury outboard?
The connecting rod bottem end is guided by the inside surfaces of the crankshaft and the top end is able to move horizontally on the piston wrist pin. Top end washers which are stepped on one side are used with this rod. Top aligned, later style.
