Randall said one reason for the smooth progress is that the general contactor, Shawmut Design and Construction, as well as many of the subcontractors, have worked with Harvard before on projects, including the Yard dormitory renovations...
Thus was born the idea for Department 260. Says Whitney: "The light bulb came on." But an unprecedented degree of automation would be required to pull it off. Reason: a representative contactor that sold for $20 in the U.S. sold for just $8 in the highly competitive markets of West Germany and Australia. To make a profit at the lower price, Allen-Bradley had to get costs down. By using automated equipment, the company could produce contactors for 60% less than it could by relying on a manual assembly line. "Labor costs," says Whitney "obviously had to be a nonissue...
...Super Contactor. Dr. Walter Joseph Podbielniak, Chicago consulting chemist, described the "super contactor" developed in his laboratories-a centrifugal machine for fractional distillation. A fractionator of the orthodox gravity type would have to be 700 ft. high, said he, to compete with his trim little machine in efficiency. Heart of the device is a conical coil which is rotated at such speed that the heated contents are squeezed by a force 1,500 times gravity. Outlets at the base of the spinning coil provide very fine separation by density. The super contactor was de-signed to extract from petroleum certain...
