Abstract: An industrial dust collection system for collecting dust created by operation of a machine comprising dust collecting and storage means remote from the machine; a cyclone chamber means associated with the dust collecting and storage means for receiving dust laden air from the machine; forced air blower fan means associated with the cyclone chamber means for establishing a continuous induced flow of dust laden air from the machine to the fan means and for establishing a flow of dust laden air from the fan means to the cyclone chamber means; flow direction control means in the chamber means for establishing a circular and axially downward flow of dust laden air within the cyclone chamber means; vortex chamber means within the cyclone chamber means for establishing an upward flow of air in the center of said cyclone chamber means; and dust discharge passage means connecting said cyclone chamber means to said dust collecting means for transfer of dust from said cyclone chamber means to said dust collecting means

Abstract: Truck mounted vacuum collector apparatus including first and second particle collection chambers having adjacent discharge openings for simultaneously emptying both chambers at a single discharge point. The second chamber is mounted on a platform forward of the first chamber. A passageway extends from the second chamber below the first chamber to a discharge opening immediately below a discharge opening in the first chamber. A hinged door covers both discharge openings. The chambers are emptied by hydraulically tilting the platform and allowing the door to swing open to permit the accumulated matter to empty from the first chamber through the corresponding discharge opening and from the second chamber through the second discharge opening via the passageway below the first chamber.

Abstract: The apparatus and method described herein comprises a sequence and arrangement of equipment and the method of operation thereof for the removal of water soluble pollutants and particulate matter from flue gases, such as those emanating from incinerators, furnaces, electric power generating stacks, etc.

Abstract: An intake air system for an internal combustion engine having an upright stack mounted on vehicle structure, as a hood, with a stack connecting assembly. An air precleaner is mounted on the upper end of the stack. The lower end of the stack is connected to tubular members which leads to the air cleaner of the engine. The mount structure for the stack has an adjustable clamp using a split ring to selectively hold the stack in a predetermined position on the vehicle.

Abstract: A filtration device and method for removing particulate matter entrained in a gas stream including a filter media with a first prescribed surface area on one side thereof; a perforated support for positioning the filter media so that one side thereof is in communication with the gas stream with the particulate matter entrained therein; a suction head defining a suction inlet therein with a second prescribed cross-sectional area smaller than the first prescribed surface area of the filter media on that side of said filter media opposite the side in communication with the gas stream; a fan for forcing the gas stream into the suction head through the filter media to separate the particulate matter from the gas stream; and drive means for moving the suction head along the filter media so that substantially all of the filter media is eventually used.

Abstract: A gas handling and cleaning system for the combustion gases of a coal-fired steam generator comprises an electrostatic precipitator which receives the combustion gases from the steam generator, a preheater downstream of the electrostatic precipitator and a wet scrubber intermediately positioned between the preheater and the stack. The temperature and humidity of the gases entering the stack are controlled by conveying regulated quantities of the gases from the exit of both the precipitator and the preheater to a location intermediate the scrubber and the stack.
