"The anode is supported on a movable frame or bracket, so it may be moved either up or down as desired, it being worked by thumb-screws at each end. "The electrolyte may consist of saturated solutions of soluble alkaline metals and earth. The sides or partitions of each compartment dip into the mercury, which must cover the 'box' evenly on the bottom to the depth of about a half-inch.
When an electric discharge is passed from a plate of metal, arranged as the kathode, to a metallic wire arranged as the anode, both sealed through the walls of a glass tube or bulb from which almost the whole of the air has been extracted, rays proceed from the kathode, in a direction at right angles thereto, and, striking the glass in the neighbourhood of the anode, produce a green phosphorescence.
"At that time my AM station consisted of a Hammarlund SP600 receiver and a home-built transmitter using an Italian Geloso VFO-exciter driving a pair of 6146s in the final, with anode and screen modulation by a pair of 807s in class AB2. I had also assembled a double conversion receiver using a Geloso front end. This was typical of the equipment used in Greece and Italy in the early 1960s.
This alone occurs while the solution is relatively concentrated. At the anode the lead is deposited as PbO and oxygen is evolved. Its removal promotes the complete precipitation of the copper. The reaction is Filter off the iron precipitate, using a washed filter, and wash five times with hot water.
When the electrodes are connected in series with the primary coil of a transformer and a source of direct current having a potential of 40 to 110 volts, bubbles of gas are formed on the end of the platinum, or alloy anode, which prevent the current from flowing until the bubbles break and then the current flows again, in this way the current is rapidly made and broken and the break is very sharp.
He called the separate atoms or groups of atoms into which bodies undergoing electrolysis are separated, the radicals, or ions, and named the electro-positive ions, which appear at the cathode, the kathions, and the electro-negative radicals which appear at the anode, the anions.
Craig was as calm as if his every-day work was experimenting on cadavers. He applied the current, moving the anode and the cathode slowly. I had often seen the experiments on the nerves of a frog that had been freshly killed, how the electric current will make the muscles twitch, as discovered long ago by Galvani. But I was not prepared to see it on a human being.
This accumulator is of the Plante type, and is modified so as to obtain a more rapid formation, a larger surface, and a symmetrical distance of the plates from each other. The liquid of the bath supplies material for both deposits, while in galvanoplastic operations the anode supplies it to the cathode.
Soon, however, radiant electricity showed properties which contradicted the picture of something flowing from one pole to the other. The cathode rays, for instance, were found to shoot forth into space perpendicularly from the surface of the cathode, without regard to the position of the anode.
His words are: 'To this anode of reasoning it has been objected that it would go to establish an immaterial principle in the lower animals which in them exhibits many of the phenomena of mind. I have only to answer, Be it so.
