1. The section of a superheterodyne radio receiver that converts the desired incoming radio- frequency signal to the intermediate-frequency value; the converter section includes the oscillator and the mixer-first detector. Also known as heterodyne conversion transducer; oscillator-mixer-first detector.

2. An auxiliary unit used with a television or radio receiver to permit reception of channels or frequencies for which the receiver was not originally designed.

3. In facsimile, a device that changes the type of modulation delivered by the scanner.

4. Unit of a radar system in which the mixer of a superheterodyne receiver and usually two stages of intermediate-frequency amplification are located; performs a preamplifying operation.

5. See <<remodulator>>

A type of furnace in which impurities are oxidized out by blowing air through or across a path of molten metal or matte.

1. Also known as nuclear converter.

2. A nuclear reactor that converts fertile atoms into fuel by neutron capture, using one kind of fuel and producing another.

3. A nuclear reactor that produces some fissionable fuel, but less than it consumes; the fuel produced may be the same as that consumed or different.
