Abstract: Disclosed herein is a spray nozzle comprising an annular head, a hollow neck, and a liquid inlet line disposed in the hollow neck. The annular head comprises a liquid inlet orifice, first and second external flow diversion surfaces, an interior circumferential channel, and an ejector. The ejector comprises a substantially smooth surface having a fixed width, the ejector extending from the point of contact with the interior circumferential channel such that in the extending direction, the substantially smooth surface increases in distance from the interior circumferential channel. Also disclosed herein is an apparatus comprising at least one such spray nozzle, and processes comprising using at least one such spray nozzle.

Abstract: An amplifier (125) includes at least one gain stage (210) for amplifying a signal received by the amplifier (125). The amplifier (125) also includes an AGC circuit (400, 500) that adjusts the amplification of the gain stage (210). The AGC circuit (400, 500) determines whether the input signal to the amplifier (125) is a digital signal or an analog signal and transforms either signal into the frequency domain, thereby automatically adjusts the processing method depending upon the type of pilot carrier signal. The AGC circuit (400, 500) also possesses the ability to process a change in the frequency of a pilot carrier signal remotely.
