    • Pre-trip operational methods and procedures for automatically checking predetermined functions and the operating performance of a controlled atmosphere system for a refrigerated container. The system includes an electronic control and electrically controlled components including an air compressor, a filter having a drain valve, a heater, a nonelectric membrane separator and two or more flow control valves for varying the purity and the flow from the membrane separator. Various pressure, temperature and safety control devices are provided in the system. The methods include display tests of the indicator lights and display segments on the controller, tests of the drain valves on the filters and of the flow control valves. Tests of the heater and its control and safety mechanisms are carried out. Automatic tests are conducted of the oxygen sensor and CO.sub.2 sensor including span tests and zero point value tests. Tests of the membrane assembly are conducted to determine if the required purity of nitrogen can be generated from the membrane separator. Pass or fail indications are provided via a display which indicates the test being conducted and the result of the test.

    • An activated sludge marine sewage disposal apparatus includes an aeration chamber immediately adjacent to a flooded settling tank, rising above a disinfectant chamber and a holding chamber disposed around the lower part of the tank. Flow from the aeration chamber to the settling tank is through a port in the common wall between the aeration chamber and settling tank, and up inside a pond separated from the rest of the tank by a downwardly flaring baffle of skirt depending from the top of the tank. A single shimmer at the center of the area at the top of the pond picks up floating solids and returns them to the top of the aeration chamber. A vent disposed directly over the shimmer continuously draws off air and gas to the aeration chamber. A sludge return line picks up heavy solids for the bottom of the tank and returns them to the top of the aeration chamber through a riser located in the aeration chamber. Liquid in the settling tank flows out through a submerged perforated pipe into a standpipe in the aeration chamber, with is located centrally in the aeration chamber, and overflows through an inverted U tube, vented to the aeration chamber, the tube connecting to a downcomer sending the liquid back through the common wall to the disinfectant compartment. When sufficient volume of fluid accumulates in the disinfectant compartment, it overflows into a holding tank, from which it emerges via a port.
