Trade name of a rugged portable electronic device that measures ground
distances precisely by determining the velocity of a phase-modulated,
continuous, microwave radio signal transmitted between two instruments
operating alternately as master station and remote station. It has a range
up to 35 to 40 miles (56 to 64 km). CF:geodimeter

A type of gyratory crusher often used for primary crushing. It has a fixed
spindle; i.e., the spindle is not suspended from above, but is mounted in
a long eccentric sleeve. Rotation of the sleeve imparts a gyratory motion
to the crushing head, but gives a parallel stroke; i.e., the axis of the
spindle describes a cylinder rather than a cone as in the suspended
spindle gyratory. Adjustment for set in the Telsmith breaker is
accomplished by placing shims between the bottom of the breaking head and
an adjusting plate--the addition of shims at this point raises the
crushing head and increases the throat opening.

A type of secondary crusher that utilizes the gyratory principle; it has a
hemispherical crushing head. Newton, 1
