New Ideas

One-Man TV. General Electric demonstrated a one-man television station, designed for small cities where present TV stations (which require a minimum of three technicians) would be too expensive to operate. Key component of the station is a double-paneled switchboard which permits the operator to cut in films, slides, transcriptions, local or network telecasts as well as run the transmitter it self. Price: $82,000 to $180,000, depending on the power.

Porous Plastic. For use in rainwear, baby pants and other items that should let in air but be waterproof, Goodyear Tire and Rubber Co. announced a "porolated" vinylfilm that is seven times as permeable to air as ordinary plastic film.

Adjustable Wagon. Omaha's American Road Equipment Co. announced an adjustable wagon to fit all farm chores, e.g., a narrow tread for harvesting corn, a wide tread for haying, and different heights for mechanical attachments. Price: $160.

Diet As You Ride. For dieting passengers, the Pennsylvania Railroad began serving a 470-calorie meal in its dining cars. The menu: tomato juice, two crackers, chopped sirloin, carrots, lettuce salad (with nonfattening dressing), half a grapefruit, tea or coffee with saccharin. Price: $2.45.

Imitation Ice Cream. California's Frozen Desserts, Inc. will start producing an imitation ice cream, made with a vegetable-oil base instead of butterfat. The frozen dessert, which California's dairy lobby unsuccessfully tried to get banned, tastes like butterfat ice cream, will cost half as much. Price: 49-c- a half gallon.

Super-Blower. For airplane research in supersonic speeds, Boeing Airplane Co. put into operation a wind tunnel whose 24-ft. fan is turned by two electric motors with 54,000 h.p. The fan can send air whistling through the tunnel at a maximum speed of 875 m.p.h. The tunnel can test scale-model planes with wing spans up to 9 ft.
