Patent number: 5037454Abstract: A gas purification apparatus which is operable utilizing an upflow direct impingement coalescer. A central inlet in the lower portion of a column expands the flow of air and liquid droplets (vertical flow to horizontal separation). The droplets lose velocity and are impinged in the packing. Migration is first outward from the main gas flow and then downward. Finally, the liquids are drained at the bottom. A collar around the central inlet insures that liquid will not reenter into the central inlet.Type: GrantFiled: December 26, 1989Date of Patent: August 6, 1991Assignee: Mann Technology Limited PartnershipInventor: David O. Mann

Patent number: 4708120Abstract: Heat exchanger apparatus and method for cooling and removing moisture from air passing from a turbocharger (10) and the like to an intake of a combustion engine (11) is illustrated wherein heat pipes (B) extend across a flow path of the compressed air to a zone (C) of ambient air external of the flow path of compressed air to transfer heat to a controlled ambient air flow in the ambient (C) passing across the heat tubes, and including a coalescer zone (D) for collecting and removing moisture from the cooled air.Type: GrantFiled: March 17, 1986Date of Patent: November 24, 1987Assignee: Mann Technology Limited PartnershipInventor: David O. Mann

Patent number: 4600416Abstract: An in-line vapor trap for removing water and/or oil vapor from a compressed air line which includes a manifold having spaced coaxial inlet and outlet openings, a hollow base suspended from the manifold, and replaceable cartridges connecting the manifold inlet to the hollow base and connecting the hollow base to the manifold outlet. A honeycomb structure is disposed in the lower portion of the base within the enclosed volume defined thereby and cooperates with the base side and bottom walls to define a zone of substantially zero air movement for collection of liquid droplets. A depression in the base bottom wall forms a liquid sump, and a drain opens into the sump for drainage of captured liquid. This drain features a continuously open annular orifice for continuous weep-drainage of liquid under pressure. The orifice surrounds a wire having an angulated head disposed within the sump which may be rotated by an operator so as to remove dirt and debris from surrounding and clogging the annular weep orifice.Type: GrantFiled: February 8, 1985Date of Patent: July 15, 1986Assignee: La-Man CorporationInventor: David O. Mann

Patent number: 4487618Abstract: An in-line trap for removing water and/or oil vapor from a compressed airline which includes a manifold having spaced coaxial inlet and outlet openings and a hollow base suspended from the manifold. A first cartridge extends between the manifold inlet and the enclosed volume within the hollow base, and includes a wire fiber pad adapted to coalesce water and/or oil vapor in air passing therethrough into droplets which are then entrained by the air and carried into the base volume. Within the base, a plate having parallel louvers or vanes upwardly struck therefrom in a direction opposed to air travel is supported with respect to the base bottom wall by a honeycomb spacer which forms a dead air space beneath the louver plate. The louvers function to trap vapor droplets which fall by gravity from the air entering the base volume.Type: GrantFiled: August 19, 1982Date of Patent: December 11, 1984Assignee: La-Man CorporationInventor: David O. Mann

Patent number: 4483417Abstract: An airline lubricator in which a diaphragm is disposed in a closed annular chamber surrounding an axial air passage to divide the chamber into an air pressure chamber and a lubricant reservoir. The air pressure chamber is coupled by an angulated pressure tube to the primary air passage adjacent the lubricator inlet. A metering tube and adjustable screw arrangement at the output of the reservoir control the amount of lubricant fed to the primary air passage as a function pressure drop across the primary air path. A ball-type check valve including an adjustable valve seat is disposed across the primary air path in opposition to the metering tube for preventing passage of lubricant in the absence of primary air flow.Type: GrantFiled: July 28, 1982Date of Patent: November 20, 1984Assignee: La-Man CorporationInventor: David O. Mann

Patent number: 4464186Abstract: A pneumatic liquid evaporator and filter comprising a metallic case or housing adapted for connection in a compressed air line and a disposable cartridge assembly removably disposed within the case. The cartridge assembly includes a cylindrical shell having an apertured end wall and a separately formed end cap dimensioned to prevent reverse insertion of the cartridge assembly into the case. A plug of wire and fabric knitted mesh construction is disposed within the shell for performing the vaporization and filtration functions. The end cap includes an apertured bullet-shaped projection which holds the plug against the shell end wall and urges surrounding plug material radially against the shell side wall. An open cavity is thus formed around the projection between the plug and end cap.Type: GrantFiled: February 9, 1983Date of Patent: August 7, 1984Assignee: La-Man CorporationInventor: David O. Mann
