...First Eleven. Once chinchilla was a prized fur, adorning the robes of kings and potentates. Annual world sales were as high as 78,000 skins in 1900. But gradually the mountains of South America, where the chinchilla lived, were swept almost clean, and the fur fell from fash ion. In 1923, an Anaconda mining engineer named Mathias Chapman captured eleven of the remaining wild chinchillas, brought them from the Andes to Southern California in an ice-cooled crate. He started breeding them and founded the domestic chinchilla industry. From his original eleven animals sprang virtually all the estimated...
Certain salts and minerals are removed from the water as it is passed through the membranes by a chemical process known as "ion exchange," which separates the various impurities according to the electrical charges they carry...
Through a non-wettable plastic tube, which avoids damage to delicate formed elements, heretofore caused by collecting with glass or rubber tubing, the blood flows into a column of resinous beads (called an ion exchange column). Here calcium is removed to prevent clotting. On this resin are collected platelets, tiny disk-like formed elements of the blood which initiate the clotting process, obtained in this machinery for the first time in substantial yield...
...components not precipitated by the zinc salts form a Stable Plasma Protein Solution which passes through a second ion exchange column to remove the sine. This solution has been successfully injected into soldiers and civilians during and after World...
Many substances, including platinum give off ions (electrified particles) when heated to high temperature. At one end of the lonophone's quartz tube is a small quartz cylinder with a coating that contains fine particles of platinum. When the platinum is heated electrically to about 1,000° C., it fills the horn-shaped cavity above it with a cloud of rapidly zigzagging ions. The ion cloud responds almost instantly to changes in the strength of a high-frequency electric field around the little quartz cylinder, and the cloud's expansion and contraction set up sound waves. When...
