Abstract: A single sideband wave generation system for a transmitter, including two oscillators whose outputs are mixed to produce an IF wave from which a carrier wave is developed. This carrier wave is modulated by an audio frequency signal, and filtered to produce a single sideband audio signal, which is then mixed selectively with the outputs of the two oscillators to develop upper and lower sidebands of a transmission frequency. The frequency difference between the two oscillators is 2.sup.n times the carrier wave frequency, with n flip flop units or their equivalent being employed to reduce the difference frequency down to the carrier frequency.

Abstract: A control device for evaporative roof cooling systems in which a lack of moisture on a sample surface actuates a valve to spray water onto a roof.
