Cleaning Process And Composition Using Fluorocarbons

View page
US Patent:
6376452, Apr 23, 2002
Filed:
Mar 31, 1999
Appl. No.:
09/282815
Inventors:
Richard M. Flynn - Mahtomedi MN
Mark W. Grenfell - Woodbury MN
George G. I. Moore - Afton MN
John G. Owens - Woodbury MN
Dean S. Milbrath - Stillwater MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
C11D 324
US Classification:
510412, 510285, 510286, 510289, 510405, 510407
Abstract:
A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.

Condensation Heating Apparatus

View page
US Patent:
5030805, Jul 9, 1991
Filed:
Feb 20, 1990
Appl. No.:
7/482237
Inventors:
Timothy A. Koenig - Maplewood MN
John A. Pignato - Centerville MN
Mark W. Grenfell - Woodbury MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
F22B 128
US Classification:
219401
Abstract:
A condensation heating apparatus particularly useful for curing abrasion resistant coatings on eyeglass lenses has an open topped chamber with a baffle assembly for reducing the loss of vapor through the open top. The baffle assembly includes a fixed vertical partition and a removable, L-shaped baffle that has a horizontal portion to cover part of the chamber and a vertical portion which also serves as a partition. The baffle assembly extends only partially into the chamber and terminates above the top of the vapor zone so that the assembly does not become hot to the touch.

Detection Medium And Method For Use In Hermetic Seal Testing

View page
US Patent:
5369983, Dec 6, 1994
Filed:
Apr 17, 1992
Appl. No.:
7/870408
Inventors:
Mark W. Grenfell - Woodbury MN
Assignee:
Minnesota Mining and Manufacturing Company - St. Paul MN
International Classification:
G01M 300
US Classification:
73 407
Abstract:
A detection medium and method for use in detecting gross and fine leaks in a hermetically sealed package. In a preferred embodiment, the detection medium includes a detectable perfluorinated gas dissolved in a detectable perfluorinated liquid. The package is placed in a bombing chamber and then exposed to the detection medium under pressure introduce the detectable liquid and dissolved, detectable gas into the package through any gross leak openings and to introduce the detectable gas and some detectable liquid vapor into the package through any fine leak openings. The package is then removed from the detection medium and air dried to evaporate any detection medium attached to an exterior surface of the package. The package is placed in a test chamber which collects detectable gas and vapor of the detectable liquid escaping through the gross and fine leak openings. A measurement instrument detects whether a component of the detection medium has escaped from the sealed package as an indication of a leak.
