A chamber connected to a main body of water by a small inlet; such an arrangement is suitable for a recording gage.
Industry:Mining
A chamber in a turbine pump consisting of a number of fixed blades. On leaving the impeller, the water is guided outward by these blades with the minimum of eddying and swirling.
Industry:Mining
A chamber in which fumes, such as those from molten metal, may be condensed by a water shower.
Industry:Mining
A chamber in which substances are artificially heated for the purposes of baking, roasting, annealing, etc.; specif.: (1) a kiln, such as a coke oven; and (2) a leer, which is used in glassmaking.
Industry:Mining
A chamber of brick or other heat-resistant material in which coal is destructively distilled. Coke ovens are of two principal types: (1) beehive ovens, which were originally built round with a spherical top like an old-fashioned beehive. They had an opening in the top and various small openings for draft at the base. The ovens were developed into banks (rows) of joining cubicles; coke in long columnar pieces is characteristic and is still known as beehive coke. Tar, gas, and other byproducts are lost. (2) Byproduct ovens, which were built in rectangular form with the front and back removable, but so arranged that they may be luted to practical gastightness and all byproducts gaseous at the high temperatures may be pumped out.
Industry:Mining
A change in crystal summetry as a result of changes in bond length or bond angles (as contrasted to reconstructive transformations). The short-range order is unchanged; the long-range order is changed. Compare: dilational transformation; reconstructive transformation; rotational transformation.
Industry:Mining
A change in the intended course of a borehole produced intentionally or unintentionally by various conditions encountered in the drill hole or by the operational characteristics of the drilling equipment used.
