US Patent:

50296337, Jul 9, 1991

Filed:

Apr 7, 1989

Appl. No.:

7/336618

Inventors:

David O. Mann - Hamilton IN

Assignee:

Mann Technology Limited Partnership - Greenville SC

International Classification:

F28D 1502

US Classification:

165 45

Abstract:

An improvement to a cooling pond is disclosed which utilizes metallic heat pipes to transmit heat from the cooling pond to the ambient air environment.

US Patent:

RE329894, Jul 18, 1989

Filed:

Jul 15, 1988

Appl. No.:

7/219918

Inventors:

David O. Mann - Hamilton IN

Assignee:

La-Man Corporation - Hamilton IN

International Classification:

B01D 5000

US Classification:

55323

Abstract:

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.

Appl. No.:

6/840040

Inventors:

David O. Mann - Hamilton IN

Assignee:

Mann Technology Limited Partnership - Greenville SC

International Classification:

F02B 2904

US Classification:

123563

Abstract:

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.

Filed:

Dec 26, 1989

Appl. No.:

7/453167

Inventors:

David O. Mann - Hamilton IN

Assignee:

Mann Technology Limited Partnership - Greenville SC

International Classification:

B01D 5304

US Classification:

55 35

Abstract:

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.
