Molten metal from blast furnaces arrives at the open hearth foundry where it is placed in a 600 ton mixing furnace, which maintains a temperature of 2100 degrees fahrenheit. The mixing furnace acts as a sort of thermos bottle, or ore storage tank. A worker is shown here preparing an open hearth furnace for charging

Auto conversion to airplane engines. With normal operations of this automobile factory suspended for the duration, the gigantic task of converting the entire plant (floor space: 500' x 900') to war production was taken over by the National Defense Plant Corporation. This involved all degrees of remodelling, the removal of old and installation of new machinery, and extensive rebuilding of the plant itself. This hand milling machine, formerly used in manufacture of automobile motors, has been converted to production of airplane engines. In peacetime it was used to mill the pulley keyway on the front of crankshafts. It cost $150 to convert this $1,800 machine with installation of a special fixture to enable milling of staking nicks at each end of crankpin oil hobs. Chevrolet, Buffalo, New York

"Share The Meat" recipes. Braised stuffed heart. Brown the hearts on all sides in fat, then place in a covered baking dish or casserole. Add a half of cup of water, cover closely and cook until tender in a very moderate oven (about 300 degrees Fahrenheit). Calf hearts require about one and a half hours, beef hearts will require much longer--four to five hours to cook till tender

Lindsay, California. The pressure of the olive press must be carefully watched, for different degrees of pressure are prescribed for the two pressings. The first yields the virgin oil, about twenty-five percent of the total oil content of the olives; the second yields refined oil

Health measures for low home temperatures. Although your government recommends that homes be kept at sixty-five degrees temperature this winter, the rooms in which infants and children up to three years play can be kept at seventy degrees. But if your toddler plays in other parts of the house, dress him warmly and put his playpen on blocks to avoid floor drafts

Production. Mercury. Rotary kiln in a mercury extraction plant at New Idria, California, in which ore is introduced to a temperature of 1,200 degrees Fahrenheit. This heat drives off the sulphur and vaporizes the mercury which is later condensed. Triple- distilled mercury is produced at the plant by the New Idria Quicksilver Mining Company from cinnabar, an ore containing sulfur and mercury, mined at a number of workings near the plant

A poster comes to life. "This is what I call warm hospitality," said Chief Radioman Evans in his dry Georgia manner as the three men stood in 140 degrees of heat looking into the open door of an electric steel furnace. The furnace makes silica steel which is used to make transformer cores. Some of Evans' radio equipment, back at his base, uses transformers whose cores may well have come from this furnace.

Science and research. Studies of non-coking coals. V.F. Parry, supervising engineer of the Golden, Colorado field station of the U.S. Bureau of Mines is "sighting a coke bubble." This procedure is used to determine if a given coke has changed its properties or it is similar to another coke. One gram of powdered coal is heated at 820 degrees centigrade for two and a half minutes. The resulting "bubble" is then compared with a standard chart to determine its characteristics, as revealed by the shape it has assumed. This research is part of a project to find ways of improving the quality of coke from western coal

Bantam, Connecticut. Defense homes. The heating unit is in the kitchen of Fred Heath's four-room apartment in the new federally-financed homes for eighty families just a few minutes from the Warren McArthur factory in Bantam. The well-insulated coal fire puts steam in the radiators and provides the heat for cooking. The tenants are well-pleased although on several nights when the temperature dropped to ten degrees below zero they were forced to replenish the fuel every two or three hours. That cigarette Fred Heath holds is not tailor-made, by the way--he likes to roll his own

Hanna furnaces of the Great Lakes Steel Corporation. Detroit, Michigan. Coke oven pusher. A long square pusher is inserted through the entire section of the coke oven, thus pushing the coke out to the other side into the freight car. This coke oven is a modern by-product oven. All the gases and vapors liberated from the coal in the cooking processes are recovered. The coal is heated from fifteen to twenty hours in a temperature of about 1700 degrees F. The gases and vapors released by the coal are condensed for the recovery of such by-products as tar, benzol, and gas. At the end of the coking period, the incandescent coke mass is pushed into the quenching car

The Saturn I (SA-4) flight lifted off from Kennedy Space Center launch Complex 34, March 28, 1963. The fourth launch of Saturn launch vehicles, developed at the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun, incorporated a Saturn I, Block I engine. The typical height of a Block I vehicle was approximately 163 feet and had only one live stage. It consisted of eight tanks, each 70 inches in diameter, clustered around a central tank, 105 inches in diameter. Four of the external tanks were fuel tanks for the RP-1 (kerosene) fuel. The other four, spaced alternately with the fuel tanks, were liquid oxygen tanks as was the large center tank. All fuel tanks and liquid oxygen tanks drained at the same rates respectively. The thrust for the stage came from eight H-1 engines, each producing a thrust of 165,000 pounds, for a total thrust of over 1,300,000 pounds. The engines were arranged in a double pattern. Four engines, located inboard, were fixed in a square pattern around the stage axis and canted outward slightly, while the remaining four engines were located outboard in a larger square pattern offset 40 degrees from the inner pattern. Unlike the inner engines, each outer engine was gimbaled. That is, each could be swung through an arc. They were gimbaled as a means of steering the rocket, by letting the instrumentation of the rocket correct any deviations of its powered trajectory. The block I required engine gimabling as the only method of guiding and stabilizing the rocket through the lower atmosphere. The upper stages of the Block I rocket reflected the three-stage configuration of the Saturn I vehicle. Like SA-3, the SA-4 flight’s upper stage ejected 113,560 liters (30,000 gallons) of ballast water in the upper atmosphere for "Project Highwater" physics experiment. Release of this vast quantity of water in a near-space environment marked the second purely scientific large-scale experiment. The SA-4 was the last Block I rocket launch. n/a
