A chemical, physical, or electrical system that either breaks down a liquid-in-liquid emulsion or keeps such an emulsion from forming.
Industry:Aviation
A chord of an ellipse that passes through its center and is perpendicular to the major axis.
Industry:Aviation
A circle drawn around the outside of a regular polygon in such a way that all the points of the polygon touch the circumference of the circle.
Industry:Aviation
A circle formed on the surface of a sphere in such a way that the plane of the circle passes through the center of the sphere. All meridians of longitude on the earth’s surface are great circles, but the equator is the only parallel of latitude that is a great circle.
Industry:Aviation
A circuit breaker in which one of the current-carrying contacts is mounted on a bimetallic strip. If more than the rated current flows through a bimetallic circuit breaker, the bimetallic strip will heat up and warp. When it warps, it snaps the contacts apart and opens the circuit.
Industry:Aviation
A circuit breaker that opens a circuit any time an excessive amount of current flows, regardless of the position of the circuit breaker’s operating handle. A trip-free circuit breaker cannot be closed into an active electrical fault.
Industry:Aviation
A circuit consisting of an inductor and capacitor connected in parallel. The impedance, or the total opposition to the flow of current, of a parallel resonant circuit is maximum at the frequency to which the circuit is resonant. A parallel resonant circuit is called a tank circuit.
Industry:Aviation
A circuit having two stable conditions. Either condition may be chosen, and the circuit will operate in that condition until it is purposely changed. The circuit will not change its condition by itself.
Industry:Aviation
A circuit in a frequency modulated (FM) radio receiver that changes deviations in the frequency of the carrier into amplitude variations of the audio-frequency output.
The audio-frequency output, used to operate a speaker, is a duplicate of the modulating signal in the transmitter.
