...Lindbergh (LL. D., Northwestern and Wisconsin) put his mechanical wits to work and in May 1931 was able to publish anonymously in Science a skimpy description of a pump which Dr. Carrel desired and he designed. It consisted of a spirally coiled glass tube, resembling a hot water heater. The top opening of the Lindbergh tube was connected to the bottom opening by a straight glass tube, and the liquid sealed into the closed tubular circuit. By standing the coil on end and wobbling it, centrifugal force pushed the fluid up to the top of the spiral. There the fluid...
...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 hydrocarbons never before obtained...
Died. Michael Idvorsky Pupin, 76, physicist, inventor, longtime (1901-31) professor of electromechanics at Columbia University, onetime Serbian shepherd boy; of uremic poisoning following anemia and influenza; in Manhattan. Chief inventions: an inductance coil for long distance telephones; X-ray technique which shortened the exposure time from an hour to a few seconds; a wireless tuning device to overcome interference; an electrolytic rectifier to handle high-frequency signals...
...John Donovan Strong and others from a plating process first hit upon by Thomas Edison. The glass disk is first thoroughly cleaned with blasts of electrons. It is then placed in a big sealed tank from which pumps suck almost all the air. Within the tank is a coil of tungsten wire covered with aluminum. When the wire is electrically heated the aluminum boils off as a vapor which, when it strikes the mirror's cool surface, condenses in a thin, even film...
...Macauley capped his word-of-mouth build-up by unveiling a brand new Model 120 with a straight-eight motor, the famed Packard lines and all the latest gadgets. Price: $980 to $1,095 F. O. B. Most noteworthy innovation was the independent front wheel assembly. Packard used exposed coil springs but added torque arms to assure wheel alignment...
