In its development, it adapted two existing technologies, In the agricultural sector, the mechanics of grain elevators provided a model for how to move solids vertical distances and in closed-loop flow arrangements. Sacony engineers modified the elevator bucket systems traditionally used by the grain industry to carry hot catalyst from the bottom to top of vessels and between vessels. 

Beryllium is obtained by electrolytic reduction of molten beryllium chloride. The element s low density makes it useful for the construction of missiles and satellites. Beryllium is also used as windows for x-ray tubes because Be atoms have so few electrons, thin sheets of the metal are transparent to x-rays and allow the rays to escape. Beryllium is added in small amounts to copper the small Be atoms pin the Cu atoms together in an interstitial alloy that is more rigid than pure copper but still conducts electricity well. These hard, electrically conducting alloys are formed into nonsparking tools for use in oil refineries and grain elevators, where there is a risk of explosion. Beryllium-copper alloys are also used in the electronics industry to form tiny nonmagnetic parts and contacts that resist deformation and corrosion. 

A grain elevator operator wants to mix two batches of corn with a resultant mix of 54 pounds per bushel. If he uses 20 bushels of 56 pounds per bushel corn, which of the following expressions gives the amount of 50 pounds per bushel corn needed ... 

A grain elevator, e.g., will never again have to measure another sample from the 1989 crop year. 

From a safety point of view, one is also interested in grain elevator and coal dust explosions. Such explosions are not analyzed in this text, and the reader... 

Mixtures of grain or coal dust and air are potentially explosive, as shown in this grain elevator explosion. 

Palmgren and Lee (1984) collected samples of grain dust (dust accumulated in the dust collection systems of grain elevators) from six grain elevators located in the New Orleans, Louisiana, area to evaluate potential occupational exposures of grain elevator personnel. Diazinon concentrations in grain dust were <0.01 pg/g for all 31 samples collected. The authors concluded that the concentration of diazinon on the grain dust posed no hazard.

Turning to the detonation of condensed EM we note that in this case the study of the equation of state of a dense gas in which repulsion of molecules is more important than their thermal motion turned out to be non-trivial (see the fundamental work by L. D. Landau and K. P. Stanyukovich).29 Water-filled EM were studied by Yu. B. Khariton.30 At present A. N. Dremin is developing ideas on the specific influence of a shock wave on the kinetics of reaction in an EM.31 For gas-dispersion systems the structure of detonation waves has become the subject of numerous studies related to explosions of coal dust husks in grain elevators, gas suspensions of dust in wood processing, etc.32,33 34 5 Works on gas suspensions have also been published abroad.36,37 In gas suspensions we may expect that the reaction rate is determined by diffusion and depends weakly on the temperature. 

The necessary distribution channels for reliable information and farmer education also were not well established. During the late 1950s, herbicide application recommendations were obtained through many of the same sources from which agricultural products were purchased, such as Farm Bureau stores, operators of local grain elevators, and feed...

Grain elevators are a major component of an extensive agricultural distribution system. Over 100,000 people are employed at the hundreds of large elevators and the thousands of small country elevators located throughout the United States . These workers are exposed to considerable amounts of grain dust which is generated each time grain is handled. 

Sampling Methodology. Air samples were taken at four grain elevator work sites and one site outside to serve as a control.
