ADSORBENT FILTER

A filter medium primarily intended to hold soluble and insoluble contaminants on its surface by molecular adhesion.

HALF-POWER POINTS

Power ratios used to define the angular width of a radar beam. One convention defines beam width as the angular width between points at which the field strength is 71 percent of its maximum value. Expressed in terms of power ratio, this convention defines beam width as the angular width between half-power points. A second convention defines beam width as the angular width between points at which the field strength is 50 percent of its maximum value. Expressed in terms of power ratio, the latter convention defines beam width as the angular width between quarter- power points.

FILTER RATED CAPACITY

The amount of contaminants a filter will hold before an excessive pressure drop is caused. Some filters have bypass valves which open when a filter reaches its rated capacity.

INTENSIFIER

A device which converts low pressure fluid power into higher pressure fluid power.

SATURATION

Condition existing when substance contains all of another substance it can hold for that temperature and pressure.
