Chet, himself, had he been in laughing mood, might have smiled at the idea of affection being born in that brief time. Yet he might have asked instead how long was needed to bridge the sharp gap of a radio-power transmitter; how much time was needed for anode and cathode each to recognize the other.
The negative ions of an electrolyte are attracted to the anode and are discharged on contact with it. Anions such as the chloride ion yield chlorine atoms, from which gaseous chlorine molecules are formed and escape. The oxygen escapes and the anhydrides, reacting with water, re-form nitric and sulphuric acids.
A silver head may be placed on the wood of a walking stick, precisely conforming on the outside to the form of the wood within. The deposit of metal in the electrotyping process always takes place at the negative pole the pole by which the current passes out of the fluid into its conductor. This is the "cathode." The other is the "anode."
Sir Richard Burton saw pile dwellings at Dahomey, Captain Cameron on the lakes of Central Africa, and the Bishop of Labuan tells us that the houses of the Dayaks are built on lofty platforms on the shores of rivers. The accounts of historians and travellers help us to understand alike the anode of construction of the Lake Stations and the kind of life led by their inhabitants.
It was he who gave the name electrolysis to decomposition by the electric current; he also proposed to call the wires, or conductors connected with the battery, or other electric source, the electrodes, naming that one which was connected with the positive terminal, the anode, and that one connected with the negative terminal, the cathode.
By raising or lowering the sleeve, thus exposing more or less of the platinum, or alloy point, the number of interruptions per minute can be varied at will. As the electrolytic interrupter will only operate in one direction, you must connect it with its platinum, or alloy anode, to the + or positive power lead and the lead cathode to the or negative power lead.
Most commercial experimental transmissions in wireless telegraphy before World War I were carried out on the "long" wavelengths, though they were not called that at the time. In the U.S.A. amateurs were permitted to use a D.C.input of 1,000 watts to the anode of the final stage of their transmitters.
In 1921 when he was in the 4th form at school he had bought two kits of parts from France and put them together with the help of his fellow-student George Grabinger. The kit consisted of a bright emitter triode in an oscillating circuit. The heater supply was a 4 volt accumulator, and a dozen or so dry cells, with an earphone in series, supplied the anode voltage.
A vacuum bulb connected between the discharge terminals of the high frequency coil, as shown in figure 101, was illuminated with a pink glow, which streamed from the negative to the positive pole that is to say, the cathode to the anode, and the glass became luminous with bluish phosphorescence and greenish fluorescence.
"You see," he explained, with forced calmness, "I apply the anode here the cathode there." The ambulance surgeon looked on excitedly, as Craig turned on the current, applying it to the back of the neck and to the spine. For some minutes the machine worked. Then the young doctor's eyes began to bulge. "My heavens!" he cried under his breath. "Look!" Elaine's chest had slowly risen and fallen.
