LOADING MASTER

Terminal representative. The shore supervisor in charge of all operators and operations at the terminal associated with the handling of products, or his responsible delegate.

PNPN DIODE

A semiconductor device consisting of four alternate layers of p-type and n-type semiconductor material, with terminal connections to the two outer layers. Also known as npnp diode.

PIGTAIL

A short, flexible wire, usually stranded or braided, used between a stationary terminal and a terminal having a limited range of motion, as in relay armatures.

PENETRATION BALLISTICS

A branch of terminal ballistics concerned with the motion and behavior of a missile during and after penetrating a target.

OUTPUT-METER ADAPTER

Device that can be slipped over the plate prong of the output tube 385 output-meter adapter output power of a radio receiver to provide a conventional terminal to which an output meter can be connected during alignment.

NEGATIVE TERMINAL

The terminal of a battery or other voltage source that has more electrons than normal; electrons flow from the negative terminal through the external circuit to the positive terminal.

LOOP GAIN

1. The ratio of the magnitude of the primary feedback signal in a feedback control system to the magnitude of the actuating signal. 2. Total usable power gain of a carrier terminal or two-wire repeater; maximum usable gain is determined by, and may not exceed, the losses in the closed path.

FILTER LIFE TEST

A type of filter capacity test in which a clogging contaminant is added to the influent of a filter, under specified test conditions, to produce a given rise in pressure drop across the filter or until a specified reduction of flow is reached. Filter life may be expressed as test time required to reach terminal conditions at a specified contaminant addition rate.

TRANSISTOR

An active semiconductor device capable of providing power amplification and having three or more terminals.

IRMINGER CURRENT

A North Atlantic Ocean current, one of the terminal branches of the Gulf Stream System (part of the northern branch of the North Atlantic Current); it flows toward the west off the south- west coast of Iceland. A small portion of the water of the Irminger Current bends around the west coast of Iceland but the greater amount turns south and becomes more or less mixed with the water of the East Greenland Current.
