Abstract: Abstract of the Disclosure A compressed single side band communication system and method in which the audio signal is compressed prior to pre-emphasis and thereafter summed with a pilot tone for further compression prior to transmission.  Initially, only the pilot tone is transmitted at full rated power to aid in acquisition of the signal by the receiver.  Thereafter, the transmitter ALC is disabled and the pilot tone is attenuated.  The receiver adjusts the frequency characteristics of the pilot tone filter and phase lock loop filter in the detector as a function of lock-on.  The delay after loss of lock-on in reverting to wide band pilot tone and wideband loop filters is varied as a function of signal strength.  The pilot tone may be modulated for tone coded squelch.  The modu-lating source is located in the return end of the phase lock loop filter.  A unique filter is provided to insure acquisition of the pilot tone.  Automatic gain control of the audio signal is responsive to the tone signal without affecting the composite audio and tone signal.

Abstract: Abstract In a centrifugal separator for the separation of two liquids the radially outermost part of the separating chamber of the rotor communicates with a central outlet chamber for the separated heavier liquid via a calibrated opening.  From the outlet chamber a channel in a stationary outlet member extends out of the rotor to a receptacle for separated heavy liquid.  Said channel comprises a shut-off valve and has between this and the outlet chamber a calibrated outlet intended to enable a certain liquid flow through at least part of the channel, while the valve is closed.  The throughflow areas of the calibrated opening and the calibrated outlet, respectively, are chosen such that, when the valve is closed, the liquid surface in the outlet chamber will be adjusted to a relatively low level, so that unnecessary heat generation is avoided.
