The rectifier consists of two castings M and S with teeth which fit together as shown, being insulated so they do not come in contact with each other.
Two brushes bear on adjacent teeth of therectifier and are connected to the compensating winding circuit across which is a shunt.

The capacity of this rectifier is from 3 to 5 amperes, which is sufficient for charging small storage batteries, running small motors and lighting small lamps.
The small starting electrode C is connected to one side of the alternating circuit, through resistance; and by rocking the tube a slight arc is formed, which starts the operation of the rectifier tube.
The rectifier gives any desired charging rate within its capacity.
Operation of Edison Rectifier The operation of the Edison rectifier may be explained as follows with the aid of figs.

Upon resumption of the main alternating current, the rectifier starts automatically.
To start the rectifier, close in order named line switch and circuit breaker; hold the starting switch in opposite position from normal; rock the tube gently by rectifier shaker.
The rectifier tube in an exhausted glass vessel in which are two graphite anodes A, A´, and one mercury cathode B.
An ammeter and rheostat may be placed in this charging circuit if the current is to be varied, or a fixed connection may be substituted on the base of the rectifier if it is to be used for the maximum duty of 8 or 16 amperes.
As shown, the rectifier is connected to a small switch and cutout.
The illustration shows the rectifier connected up and charging an ignition battery of five Edison cells.
This also applies if the charging be done from a mercury arc rectifier without attendance.
Barbet rectifier and the other a rectifier of the Gillaume type combined with inclined column still.
Such a current could not be maintained by the rectifier, because as soon as the zero value was reached the negative electrode resistance of the rectifier would be re-established and the circuit would be broken.
There are several classes of apparatus to which the term rectifier may be applied, as 1.
The positive electrodes of the rectifier thus act as check valves, permitting current to pass into the mercury vapor but not allowing it to pass from the vapor to the solid electrodes.
The rectifierbulb is provided with three positive electrodes or anodes, a negative electrode or cathode, and a starting anode, as shown.
The action of the rectifier will be better understood by reference to the diagram of current waves and impressed pressure as shown in figs.
The overlapping of the rectifier current waves reduces the amplitude of the pulsations and produces a comparatively smooth direct current as shown in curve III.
The cut shows front, rear, and side views of the rectifier, illustrating the arrangement on a panel, of the rectifier tube with its connection and operating devices.
The rectifier may be joined in series for producing an increased voltage or two tubes can be connected in series in a single set.
In small rectifier sets the heat generated is dissipated through the tube to the air, and in large tubes such as used in supplying 40 to 60 kw.
It consists of a constant current regulating transformer, a rectifier bulb, and a control panel containing the necessary switches, meters, etc.
Move regulator R to the extreme right step by step and note that the ammeter continues to return to zero, which indicates that the film on rectifier electrodes is formed properly.
The part M of the rectifier is connected to one of the collector rings by F, and the part S to the other ring by G.
The positive pole; a term used mostly with electrolytic devices, also with the mercury arcrectifier and the electric arc.
A coil used in connection with a mercury-arc rectifier for tilting or shaking the tube and starting the apparatus.
This type of rectifier is entirely automatic and is much used.
In Figure 149 a complete diagram of the connections of the General Electric Company Mercury Arc Rectifier for moving-picture arcs is given.
While the current from the rectifier is always in the same direction, positive from B to the lamp, it is also a pulsating current changing in value to some extent.
The mercury-arc rectifier has three essential parts: the rectifier tube, the main reactance, and the panel.
Figure 133 shows a method by which it is possible to arrange for either one of two arcs to be run from a rectifier R, indicated by the square at the left, or transformer T, at the right.
The rectifier tube, Figure 149, is a glass vessel from which the air has been exhausted and in which there are two graphite electrodes, A and A', and one mercury electrode B.
To insure careful handling and safe delivery, Mercury-Arc Rectifier tubes are always shipped by express in the special box as they come from the factory.
The name sometimes given to a reactance used in connection with a mercury-arc rectifier to cause an overlapping of the two currents from the anodes.
Make a diagram of the mercury-arc-rectifier circuits.
Mercury-Arc Rectifier Circuits] The circuit of a mercury-arc rectifier charging outfit is shown in Fig.
The mercury-arc rectifierproper consists of a glass bulb containing vacuum and a small amount of mercury.
If the local power circuit carries alternating current, a converting device of some sort must be used and for this purpose, if the exchange is large enough to warrant it, a mercury rectifier is an economical and simple device.
These condensers are used in connection with the reactance coil to smooth out the pulsating direct current after it has passed through the rectifier tube.
The vacuum tube rectifier is simply a two electrode vacuum tube.
The trade name of a vacuum tuberectifier made by the Radio Corporation of America.
The malt distiller is not allowed to furnish, under a heavy penalty, any crude or raw spirit to the rectifier or manufacturer of gin, of a greater strength than seven per cent.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "rectifier" in a variety of sentences. We hope that you will now be able to make sentences using this word.
