Hamilton Solidum discovers ICAP.*
Glines & Rhodes refines recoverable precious metals from a wide variety of waste and by-product materials. But before refining can begin, the metals to be extracted must be known and measured. With confidence and accuracy.
Other methods require complex sample preparation and a high degree of operator skill to get reliable results. Running the ICAP Spectrometer couldn't be easier. Just introduce the sample, enter a few simple keyboard commands, and a complete multi-element analysis is printed out in less than a minute.
That's why Mr. Solidum's discovery of •Inductively Coupled Argon Plasma spectroscopy from Jarrell-Ash has become so Thanks to their ICAP Spectrometer from important at Glines & Rhodes. Jarrell-Ash, the folks at Glines and Rhodes are spending more time recoverOther methods of elemental analysis, like ing more precious metals, and a lot less fire assay and atomic absorption, can time in the lab. analyze just one element at a time. Mr. Solidum's ICAP Spectrometer detects and Jarrell-Ash has prepared detailed applicaquantifies eighteen target metals from the tion notes for a number of laboratory and same sample, in the same test, regardless industrial uses. Precious metals analysis is of concentration. Even difficult metals one of them. For more information about like platinum and palladium. So precious how ICAP spectroscopy from Jarrell-Ash metals that someone else may not even can make your elemental analysis easier, think to look for are routinely discovered faster and more accurate, call or write and turned into profits.

Reinforced plastics on road to recovery If reinforced plastics producers are correct, 1982 will bring them back close to 1979's record production level after a disasterous 1980 and a so-so 1981. And next year's level may even exceed the record. A consensus of producers is that 1982 volume growth will fall short of last year's; thus demand for reinforced plastics will not hit 2 billion lb yet this year. They predict that shipments will grow 5.2% from last year to 1.92 billion lb in 1982. Last year, reinforced plastics shipments rose 7.5% from 1980 levels to 1.82 billion lb. These figures were revealed last week at the annual conference of the Reinforced Plastics/Composites Institute of the Society of the Plastics Industry held in Washington, D.C. The figures are part of a survey of producers and others in the industry compiled by Laura Morrison of the public relations firm Morrison-Gottlieb, New York City. According to the survey, the biggest growth category for reinforced plastics in 1981 was the aircraft industry. This market, though the smallest charted by the survey, increased 12% from 1980 to 28 million lb. Aircraft use of reinforced plastics is expected to maintain its growth lead again in 1982, climbing 10.7% to 31 million lb. The biggest use of reinforced plastics—land transportation—had one of the slowest demand increases in 1981. This was, of course, because of the sluggish automobile market. However, in spite of the cries of woe coming from Detroit, reinforced plastics managed a 7% increase in use for land transportation in 1981 to 445 million lb. However, reinforced plastics makers see demand for their products for land transportation struggling for only a 2.7% gain in 1982 to 457 million lb. The reinforced plastics market hardest hit by the recession has been marine uses, suffering longer and harder than other markets. Unlike the other markets, marine uses, mainly for small, recreational boat hulls, reached their peak in 1978 at 430 million lb and then declined solidly for two straight years, followed by only a 5.5% increase in 1981 to just 290 million lb. For this year, producers expect no growth in marine uses, so consumption by the end of 1982 still will be 33% less than peak demand in 1978. This is

hardly surprising, though, because during a recession recreational markets for any product are usually the first to slip. Construction uses for reinforced plastics, in spite of continued recession and high interest rates, chalked up a relatively good increase in 1981 of 7.7% to 309 million lb. However, growth in this area is expected to slow in 1982 to 5.8%, with demand likely hitting about 327 million lb.
Other than aircraft markets, the best growing outlets for reinforced plastics last year were in corrosionresistant equipment and electrical products. Corrosion-resistant equipment uses increased 9.1% to 275 million lb in 1981, and electrical markets grew about 9.9% to 178 million lb. These two markets are expected to continue to do well this year. The survey indicates that the market in corrosion-resistant equipment may
increase a further 9.8% in 1982, and that in electrical uses may rise at an even faster 10.1% Thus, reinforced plastics, many of whose uses are closely tied to the economy and are therefore highly cyclical, are beginning to recover. But, even with a 5.2% growth this year, the industry still will be almost 7% below consumption levels in 1979, its most recent good year. William Storck, New York
