...hamburg, fed Coming's stray dogs on the results of their experiments. They cooked on wood, oil and coal stoves, five types of gas ranges, twelve kinds of electric ranges. Sometimes they cooked until the food was burned dry, to see if the glass would stand the continued heat. Eventually they found a glass of which each centimetre expanded only .00000385 cm. per degree of temperature raised, and which continued to hold its heat-resisting properties even through many reheatings...
...solving the problem of the windowless structure, Owens-Illinois claimed that it had taken a long step forward in making air-conditioning practical. The glass house also contains another important Owens-Illinois product: spun glass, or glass wool, woven into thick mats and used as insulator of heat and sound. It is likely to be a long time before many people live in glass houses, but glass insulation is a much more immediate rabbit in the Owens-Illinois...
...between 4? and 5? but make 20 trips at an average cost of about ^ a trip. The paper con- tainer costs from 1¼? to 1½?, makes only one trip. But it is much cheaper to deliver milk in paper than in glass. A 1½-ton truck (heat insulated and requiring no ice ) can deliver 2,000 quarts of milk weighing 4,000 lb. The same 2,000 quarts delivered in a non-insulated five-ton truck would include 4,000 lb. of milk, 4.000 lb. of glass, 2,500 lb. of wooden cases...
...Harvard graduate who worked in the glassblowing department before becoming a company executive and who heads the Boy Scouts in the Corning district. The Corning Glass Works makes electric light bulbs, thermometers, rail-way-signals, laboratory equipment, art-glass, all manner of glass specialties. It developed Pyrex. a heat-resisting glass most familiar in the form of baking-dishes but also used in radio and other insulation...
Iron Fireman introduced a model which put coal on nearly an even footing with the automatic appeal of oil or gas, since the coal was conveyed from bin to furnace without the intervention of a shovel. Aside from convenience, the strongest selling point for mechanical stokers is economy. More heat is obtained from less coal. Stokers have offered hope to the coal industry, since they mean real competition for the oil burner...
