Last week the metallurgical journal Metal Progress commented on the researches of Professor Daniel Hanson of England's University of Birmingham, who had divided creep into four stages. These are elastic stretch (like rubber); plastic flow (like mud); slower plastic flow; approach to fracture. Professor Hanson's theory of fracture is that the metal atoms, under continuing mechanical stress plus their own agitation due to heat, are moved one by one to new positions so that the whole structure is weakened. When enough atoms are thus individually moved, the metal breaks...
...Boston-born in 1890, it has since been squeezed out there and almost everywhere else by simpler & slower squash racquets, nowadays is largely the hobby of a fairly small group of players in the Manhattan area. It is played with a green, net-covered, two-and-one-half-inch rubber ball and a ten-ounce lawn-tennis-style racquet on a 32-by-18½-ft. court. Players alternate in serving against a wall, score points only while in service...
...want more than a peek at the ground out of an open side window before landing in rain or ice, was a windshield wiper which is designed to: 1) keep ice off the glass, and 2) scrub it dry in the heaviest rainstorm. Trick of the device is a rubber, motor-driven blade, pivoted on an axle through the windshield. It revolves so fast (2,500 r.p.m.) that it does not obstruct vision, scrubs glass many times faster than a slow-moving automobile wiper. To help it rub away ice, a melting mixture of glycerin and alcohol is fed through...
...French scientist named Maurice Piettre, when he arrived in the U. S. for a conference on food processing, told of new wrapping material then being tried in France for refrigerated meats. The material was latex-pure natural rubber altered just enough to be workable. The trick sounded good to Dewey and Almy Chemical Co. of Cambridge, Mass., which was already using latex to make low-cost balloons ($2.25) for high-altitude meteorological and cosmic ray observation. The company's researchers set to work devising a commercial method for wrapping poultry and meat in latex...
Last week "Cryovac" bags were being tested for consumer appeal by four packing companies. A difficulty: some people have a prejudice against rubber as a food wrapper. Dewey and Almy is confident that this will be overcome, since their latex is odorless, tasteless...
