- noun A worker who blends or dilutes whiskey or other alcoholic beverages.
from The Century Dictionary.
- noun One who or that which rectifies.
- noun One who reflnes a substance by repeated distillations or by filtering or any other method; specifically, one who rectifies liquors.
- noun In the distillation of alcoholic liquors:
- noun A vessel or receptacle in which a second distillation is carried on, to condense the liquor and increase its alcoholic strength, or to flavor it by exposing the flavoring substance to the vaporized spirit.
- noun A cylindrical vessel continuous with a primary still, in which repeated distillations occur till the alcohol reaches the desired strength. Also called
rectifying column, and simply column
- noun An instrument formerly used for indicating the errors of the compass.
- noun In elect, an apparatus for changing an alternating electric current into a direct current directly, that is, without intermediary transformation of energy. The most common forms of rectifier are: The mechanical rectifier, which consists of a synchronous motor (that is, a motor which keeps step with the alternations of the alternating current) driving a rectifying commutator which reverses the direction of successive impulses of current so as to send them in the same direction into the direct-current circuit. The main objection to this form is the destructive sparking of the commutator-brushes when rectifying large amounts of power.
- noun The electrolytic rectifier which is based on the property of aluminium, in some salt or acid solutions, of passing current only when negative: a property due, probably, to the formation of a non-conducting film of oxid or basic salt on the aluminium by the oxygen produced on the aluminium when it is the positive terminal. Such a rectifier usually consists of an aluminium and a carbon or metal plate in a solution of some suitable salt. A combination of this sort passes only one half-wave of alternating current, from the carbon to the aluminium, but partly suppresses the reverse half-wave; and by using two such rectifiers, one half-wave of current is passed over the one, the other over the other rectifier, and then recombined and sent into the direct-current circuit. The disadvantage of the electrolytic rectifier is its low efficiency.
- noun Arc-rectifiers, which are based on the property of arcs to be conducting in one direction, but not in the opposite. In the mercury-arc rectifier, one mercury and two graphite terminals are inclosed in the same glass tube, the two graphite terminals being connected to the terminal of the alternating-current supply, while the direct-current circuit connects between the mercury terminal of the rectifier and a neutral or midway point of the alternating-current circuit, derived from a three-wire transformer or compensator, or by reactances. One impulse of the alternating current then passes from one graphite electrode, the other from the other graphite electrode; but both issue, in the same direction, from the mercury electrode into the direct-current circuit. The mercury-arc rectifier has a very high efficiency, but is so far limited in the amount of current which it can rectify. It is used for charging storage batteries and for arc-lighting.

I electrolyzed molten NaOH using a step-down transformer and rectifier from a model train set, the nickel crucible as cathode, and a carbon rod salvaged from a dead flashlight battery as anode.
Thus the current in the rectifier is controlled through the injection of holes.
Direct current may be obtained from an alternating current supply by use of a current-switching arrangement called a rectifier, which contains electronic elements
To be certain, the forum member from yesterday was only using specious emotional arguments in order to try and limit your lawfully carrying a firearm, while "rectifier" is advocating cold-blooded, premeditated murder, but in the end, they are both seeking to accomplish the same thing: control over your life, and limiting your rights.
Just so everyone is clear, this individual, who writes under the psuedonym of "rectifier", is advocating the premediated, cold-blooded murder of American citizens, with malice aforethought, after first laying in wait for those citizens, and enticing them into a trap.
"rectifier" 's comment - somehow, proposing and supporting the murder of law-abiding citizens actually violates the SFGate's user agreement.
We were dispersing such an amount of power in this four test tube rectifier for the high tension.
I think someone produced two lantern cells which did for a while, but it was mainly on this home-made cell system, which wasn't efficient but nowhere near as inefficient as the rectifier was.
Because of frequent power failure or no power, diesel generator, battery bank, inverter, rectifier, and now increasingly solar PV and associated charge controller are inter-connected with frequent switching from one device to the other to meet electricity supply 24/7, and this leads to special fire risk.
