...least one think tank working for it. Think tanks usually work on a whole range of problems at the same time: strategic weaponry, nuclear contingency plans, new ideas for preventing and fighting crime, stinging rebukes to Federal agencies, development of HoJo Cola, the Lark filter, freeze-dried foods, the location of Disneyland and thousands of other problems land desired innovations...
Together with his sons, Floyd Jr., 49, and Bruce, 38, Floyd Gottwald is trying to convince the Government and the automakers that his company's new "lead trap," a disposable filter attached to an auto muffler, will stop lead from being emitted into the air. Trouble is, Ethyl's device does not trap all the lead. Besides, automakers claim that lead must be kept out of the gasoline itself because it clogs catalytic mufflers. These are metal containers for the chemicals that will remove enough air pollutants from auto exhausts to meet federal standards set for 1975.* Says...
MEETINGS of this pattern are repeated again and again, and if the effect is sometimes artificial, the figure of the writer which emerges is a rich and full one seen through the particular filter of an intense young poet in Prague in the early twenties. Gustav Janouch's father worked with Kafka at the Insurance Association and asked him to advise the son on his poetry. The resulting introduction, in March of 1920, led to several years of close friendship and to the manuscript which became the Conversations. The jottings which Janouch assembled were first published in 1951 with...
...whole. It cannot be treated as a bottomless sewer, capable of absorbing any amount of pollution. In fact, says Piccard, "Phytoplankton, the primitive plant life that generates most of the earth's oxygen, is surface matter. It absorbs dirt and acts as a sort of pollution filter. Thus all you need to knock out is the surface phytoplankton, and the entire marine life cycle is fatally disrupted." That disruption is accelerating logarithmically. At one Baltic measuring station, Environmentalist Barry Commoner points out, the oxygen content of water samples was 2.5 cc. per liter in 1900. The figure gently declined...
...casual Parisian passerby, the contraptions look like smokestacks or versions of Colonnes Morris, pillars handy for posting theatrical notices. Actually, the two 16.5-ft.-tall towers just erected in the Gare de Lyon section of Paris are huge, electrically driven vacuum cleaners designed to suck in dust, filter it and blow clean air out the top. "Clear the air! Wash the wind! Clean the sky!" as T.S. Eliot put it. If tests made of the surrounding air show that the towers really work, 50 to 100 more may be set up around the city. But that would require more electricity...
