Abstract: ABSTRACT         There is described a digital sonar receiver having a novel beamformer, own doppler nullifier (O.D.N.), and adaptive time varied gain controller.  The beamformer interrogates a multi-element transducer by utilizing an interleaved sampling scheme which samples the elements in the transducer array sequentially, in such a fashion that continuous, uniformly spaced samples are obtained.  The samples are subsequently converted into digital format, weighed and summed.  The O.D.N. eliminates the own ship's doppler effect on the beam output signal resulting in a half beam output signal representative of the target doppler. The O.D.N. offsets the frequency of the beam output signal and a digital generated signal representative of the own ship's doppler.  The O.D.N. multiplies these two offsetted signals resulting in a signal lying in each of the sum and difference frequency bands for which the signal lying in the difference frequency band corresponds to the target doppler.  The adaptive time varied gain controller varies the gain of preamplifiers at the input of the sonar receiver to be inversely proportional to the momentary average reverberation level of the medium in which the receiver operates.  The adaptive time varied gain control apparatus initially sets the gain of the preamplifiers to be inversely proportional to a standard reverberation curve during the first ping-cycle and subsequently updates the gain of the preamplifiers during each successive ping-cycle by computing a gain correction from the average value of a pre-determined number of beam output signals.

Abstract: ABSTRACT           A vacuum operated sewerage system includes a static pressure sensor establishing a trigger signal at selected first level in a standpipe.  The sensor is connected upstream of a discharge control valve and actuated a timer at the selected sensed pressure.  The timer is connected to actuate the discharge control valve after a suitable time delay to prevent transient signal actuation, and establish flow for a predeter-mined period.  An air admission valve is connected in series with the sensor to the timer to actuate the timer if the system vacuum drops below a selected level in the same manner as an increased hydrostatic pressure.  The sensor can be eliminated for separate air admission control directly in response to the vacuum condition of the line.
