Metal Gasket And Method Of Manufacturing
US Patent:
6357758, Mar 19, 2002
Filed:
Jun 30, 1999
Appl. No.:
09/344282
Inventors:
Thomas O. Zurfluh - Evanston IL
Assignee:
Federal-Mogul World Wide, Inc. - Southfield MI
International Classification:
F02F 1100
US Classification:
277595, 277951, 298883, 148661
Abstract:
A metal gasket for use in sealing between a cylinder head and a block of an engine includes at least one layer formed with at least one opening therethrough and a deformation feature in the form of a sealing bead, stopper, or both surrounding the opening. The gasket layer is fabricated of austemper-hardenable steel formed when in an annealed state and thereafter austempered to harden the layer and relieve residual forming stresses. During austempering, the layer is supported in a porous fixture that retains the layer against movement out of its plane while permitting it to move within its plane. The fixture has coarse expanded metal exoskeleton liner with wire mesh panels. The mesh liners maintain molten salt against the layers which acts as a thermal cushion to discourage warpage.
Heat Treat Fixture Apparatus And Method Of Heat Treat Hardening Thin Metal Work Pieces
US Patent:
6491865, Dec 10, 2002
Filed:
Dec 5, 2000
Appl. No.:
09/730043
Inventors:
Thomas O. Zurfluh - Evanston IL
Assignee:
Federal-Mogul World Wide, Inc. - Southfield MI
International Classification:
C21D 900
US Classification:
266274, 432261
Abstract:
A heat treat fixture is provided for supporting thin sheet-like work pieces, such as metal gasket layers, during heat treatment to achieve uniform hardness and properties of the work piece while preventing warpage. The fixture has porous, planar support walls that engage the opposite sides of the work piece. The walls include a coarse porous exoskeleton of expanded metal and an inner liner of wire mesh panels that are considerably finer than the coarse exoskeleton. The porous walls permit liquid heating and cooling media during heat treatment to flow freely through the walls for intimate contact with the work piece to achieve rapid uniform heating and cooling. The work piece is supported by the porous walls against movement out of its plane while being permitted to expand and contract within its plane to minimize warpage.
Metal Plate Gasket
US Patent:
6682079, Jan 27, 2004
Filed:
May 31, 2002
Appl. No.:
10/158814
Inventors:
Robert M. Reisel - Mt. Prospelt IL
Thomas O. Zurfluh - Evanston IL
Thomas O. Zurfluh - Evanston IL
Assignee:
Federal-Mogul World Wide, Inc. - Southfield MI
International Classification:
F02F 1100
US Classification:
277590, 277591, 277598, 277628
Abstract:
A metal gasket assembly has a gasket plate and an annular grommet. The gasket plate is formed with an opening having opposing surfaces adjacent the opening to define a predetermined fixed thickness of a plate. The annular grommet has an elastically deformable U-shaped body. The U-shaped body has legs presenting outer sealing surfaces defining an initial undeformed thickness that is greater than the thickness of the gasket plate. The opening formed in the gasket plate receives the grommet. A compressive force applied in a generally perpendicular direction to the opposing surfaces of the gasket plate deform the legs of the body to a reduced thickness corresponding substantially to the thickness of the gasket plate. When the compressive force is reduced with changes in operating conditions, the legs of the grommet return toward their original undeformed thickness to maintain a seal.

Abstract:
The invention provides a sheet metal joint and a method for forming a sheet metal joint. The sheet metal joint includes first and second metal sheets disposed in a parallel relation to one another. Each of the first and second metal sheets has a plurality of perforations with a tang extending from each perforation. The tangs of the second sheet and the tangs of the second metal sheet are curled together in opposite rotational directions. The tangs of the first metal sheet space the first and second metal sheets from one another and the tangs of the second metal sheet substantially fixedly engage the first and second metal sheets with respect to one another.
