PARTIAL ARC ADMISSION

In multi-valve turbine inlets, partial arc ad mission allows the steam to enter per valve opening in a sequential manner, so as load is increased, more valves open to admit steam. This can cause uneven heating on the high-pressure annulus as the valves are individually opened with load increase.

PELORUS CARD

The part of a pelorus on which the direction graduations are placed. It is usually in the form of a thin disk or annulus graduated in degrees, clockwise, from 0° at the reference direction to 360°.

CLOSED STEAM

Steam that flows through a heating coil or annulus so that there is no direct contact between the steam and the material being heated.

CONCENTRIC TUBE COLUMN

A carefully insulated distillation apparatus which is capable of very high separating power, and in which the outer vapor-rising annulus of the column is concentric around an inner, bottom-discharging reflux return.

PASSBAND

A frequency band in which the attenuation of a filter is essentially zero.

PARABOLIC MICROPHONE

[ENG ACOUS] A microphone used at the focal point of a parabolic sound reflector to give improved sensitivity and directivity, as required for picking up a band marching down a football field.

MONOCHROMATIC EMISSIVITY

Theratio of the energy radiated by a body in a very narrow band of wavelengths to the energy radiated by a blackbody in the same band at the same temperature. Also known as color emissivity.

MARMON CLAMPBAND

A metal band that wraps around the circumference of a special cylindrical joint between two structures, holding the structures together.

INTRINSIC DETECTOR

A semiconductor detector of electromagnetic radiation that utilizes the generation of electron-hole pairs across the semiconductor band gap.

HOSE CLAMP

Band or brace to attach the raw end of a hose to a water outlet.
