Industry:Mining
As used by the diamond-cutting and diamond-bit-setting industries, the more or less flat diamond fragments produced by splitting a crystalline diamond along the octahedral plane. Such fragments are used primarily as a material from which special-shaped, diamond-pointed cutting tools are produced.
Industry:Mining
As used in flotation, a form of floating control system in which the manipulated variable may change at two or more rates each corresponding to a definite range of values of the actuating signal.
Industry:Mining
As used in flotation, a system in that the rate of change of the manipulated variable is a continuous function of the actuating signal.
Industry:Mining
As used in flotation, the component of proportional plus rate action or of proportional plus reset plus rate action for which there is a continuous linear relation between the rate of change of the controlled variable and the position of a final control element.
