When the car was gone over for the second time, by a reliable mechanic and the Consumers' Aid representative, it was found that most of the valves were stuck and had never been removed or cleaned, and that the cylinders were full of a mixture of dirt, pieces of carbon, and anti-freeze. This took place after Snell had charged $42.80 for general repairs which included grinding the valves, replacing certain of the hydraulic lifters, and thoroughly cleaning out the engine...
...magnesium program was to enlist a new process that uses less power than present electrolytic methods: ferrosilicon. Pulverized and mixed with calcined dolomite (a common magnesium ore), the ferrosilicon reduces the ore in a vacuum, and magnesium of high purity results. Henry Ford, Union Carbide & Carbon and Canada's Dominion Magnesium Co. have been experimenting with the process for three years. All three will share in the new manufacturing program. So, using this or their own process, will American Metal Co., National Lead Co., Permanente Metals Corp., Dow Chemical (at present the only volume producer of magnesium), Mathieson Alkali...
...cooled, pulped (fruits are pulped raw), then sprayed in a 3/1,000-in. film on revolving drums, where heat drives off 96% of their water in ten to 20 seconds. Steam rising rapidly from the food prevents oxidation, as when apples turn brown. Vacuums (or inert gases such as carbon dioxide) are sometimes used to keep air away. Tomatoes come off the drum like an endless sheet of red crepe paper, crumble into microscopic flakes which will store well for at least three years. Best products: tomatoes, potatoes, apples, bananas, peaches, peas, squash, pumpkin...
...plant kingdom except for the muscling-in of a little-known group of microscopic water animals.* Unlike the 850,000 other species of animals, which live parasitically off the food-making ability of the plant world, these little creatures contain chlorophyll and hence can synthesize food out of water, carbon dioxide in the presence of light. And unlike any of the 250,000 species of plants, one of these animals-Euglena rubra by name-changes its color, now red, now green, to control the amount of light it uses. This phenomenon was explained last week in Physiological Zoology by Leland...
...floor study Edmonds works according to an erratic method all his own. He never knows when he begins a novel how it is going to end. He never takes notes on his research. Having a very poor memory, he often has to do research over & over. He never makes carbon copies of his novels. "Something terrible is going to happen as a result," he says, "but I can't write if I've got to fiddle around with carbons in the midst of writing...
