Laboratory caster

The basic principles of the tape casting process are included in most of these machines whether they are laboratory casters or production-scale models. The major components needed for tape casting include a solid, level casting surface, a drying chamber with a built-in means for controlling the airflow over the drying tape, an adjustable speed carrier drive control with a constant speed regulation mechanism, an air heater to control the temperature of the filtered feed air to the...

The guanidinothiazole group appears to confer high affinity at the H2-receptor, and many active derivatives are now known. Only one of these, however, has become a therapeutically useful drug this is a sulfamidoamidine analogue discovered in the laboratories of the Japanese Company, Yamanouchi. This compound, famotidine (YM 11170 Fig. 1.2) is about 30 times more potent [15] than cimeti-dine in man, and is marketed in Japan as Caster and in Western countries by Merck Sharp and Dohme (under license from Yamanouchi), under the trademark Pepcid . 

NEDCC is located in Abbot Hall on the campus of Phillips Academy in Andover, Massachusetts. It is the only regional center in the country specifically oriented to conservation of library and archival materials as opposed to museum collections. Having begun life in the basement of the Merrimack Valley Textile Museum, we are pleased that we now have windows on all four sides. We have a large, spacious paper conservation laboratory, and specialized equipment such as our Israeli-made leaf caster. This is used to fill losses in book pages or documents and to reinforce crumbled edges. 

In the laboratory, large-scale industrial plants for paint application are often simulated with simple coating equipment. The most commonly used devices for producing films on test panels are the film applicator, film caster, film spreader, and...

Photometric Scale. Calibration of the photometric scales of spectrophotometers is, paradoxically, both much studied and much neglected. This is because a few devoted workers have carried on elaborate collaborative studies in an effort both to appraise the magnitude of interlaboratory variance attributable to instrument calibration difficulties and to devise suitable standards which others can use. However, lamentably few of the world s spectrophotometers are routinely subjected to a systematic scrutiny in this regard. Ten years have passed since Caster, in his study of the variability of the Beckman DU (122), stated, One should be slow to attribute significance to discrepancies of 5% or less in the Ei values reported by different laboratories or even between different sets of absolute values obtained within the same laboratory at markedly different times. The situation has improved a little since then, but the gains must be credited more to the manufacturers of spectrophotometers than to the diligence of spectrophotometrists.
