Abstract: During the normal operation of a liquid-cleaning filter cartridge, which is located in a pressurizable inverted bell housing, contaminates are filtered through a sheet of wire mesh arranged in a star configuration on a frame structure within the filter cartridge. Contaminates collect on this filter bed, thus cleaning the dry cleaning solvent. During the system's backwash cycle, filtered solvent previously collected in a steel reservoir is pressurized to provide a powerful head of pressure for backflushing each filter cartridge through its own sprayer nozzle assembly which reciprocates inside the cartridge. The high-pressure spray vigorously cleans the wire mesh of all suspended contaminants and filter bed particles.

Abstract: Cleaning solvent is sprayed about the periphery of the air intake of a gas turbine engine in that area of the intake where the air speed is turbulent and relatively slow. The pattern of spray is created by a plurality of nozzles uniformly spaced about the periphery of the air intake. The nozzles each have an arm bent at an angle of approximately 30.degree. and mounted to create a spray pattern of a fan shape at an angle of 90.degree. respecting the exit aperture of the nozzle. The spray cloud thus created in the area of low speed relatively turbulent air before the compressor of the engine creates a uniform intake of cleaning fluid into the engine when the engine is operated at or near full speed and at or near full load. The 90.degree. fan shape pattern at the nozzle aperture narrows to 60.degree. when the engine reaches operating speed and load.

Abstract: A miniature flat spray nozzle is disclosed which delivers a fan-shaped mist of fuel to a gas turbine combustor from a narrow slot. The slot is formed by making a transverse cut in a fuel-carrying conduit at a location near its end.
