Apparatus for determination

A useful approximation of B for a conical hopper is B = 22f/a, where a is the bulk density of the stored product. The apparatus for determining the properties of solids has been developed and is offered for sale by the consulting firm of Jenike and Johansen, Winchester, Massachusetts, which also performs these tests on a contract basis. The flow-factor FF tester, a constant-rate-of-strain, direct-shear-type machine, gives the locus of points for the FF cui ve as well as ( ), the...

MESG is defined in terms of die precise test mediod and apparatus used, of which there are three variants British, lEC, and Underwriters Laboratories, Inc. Each apparatus consists of two combusdon chambers connected by a slot of specified size and variable widdi. The separate chambers are filled with the test mixture. The MESG is die maximum slot widdi that prevents flame propagadoii between die chambers for all composi-doiis of die test gas in air under the specified test coiididoiis. Phillips (1987) describes and compares diese three types of experimental apparatus for determining the MESG.

Smelter fumes which damaged crops, fodder, and stock were a serious problem. While Professor Carl Friedrich Plattner was studying means of removing sulfur dioxide, Reich devised a simple apparatus for determining the sulfur dioxide content of vapors and gases. Even the erection at Hilbersdorf of the tallest smokestack in Europe failed...
