International Classification:

F02F 1100

US Classification:

277592, 277627, 277652

Abstract:

An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.

12/781030

Inventors:

Brian C. Lehr - Lancaster PA, US
Derek J. Martin - Leola PA, US
G. Scott Dossey - Oak Park IL, US

International Classification:

F16J 15/10
B23P 11/00

US Classification:

277630, 29428

Abstract:

A segmented gasket is formed from two or more gasket segments arranged end-to-end. In one embodiment, the end portions of the gasket segments overlap a predetermined amount to define a region of overlap having a thickness greater than the thickness of the individual gasket segments. An embossed region extends along the gasket segments and aligns in the region of overlap. When compressed between two flanges to be sealed, a continuous seal is formed from one gasket segment, across the region of overlap, and to the other gasket segment. In another embodiment, the gasket segments are locked together with interlocking tabs that project laterally from the end portions of the gasket segments and that are positioned outside of a joint within which the gasket segments are clamped. In a preferred embodiment the gasket segments are metal or rubber coated metal core gasket segments.

Assignee:

Armstrong World Industries, Inc. - Lancaster PA

International Classification:

G01J 350

US Classification:

250205

Abstract:

A lighting control system for maintaining the light source and measuring components of a color measurement station in a stabilized condition. A high frequency fluorescent lamp drive is controlled by a ballast which is adjusted by a control signal generated by using a video camera to simultaneously view a standard tile and a test sample. One of the color signals in the standard tile portion of the signal is compared with prescribed information stored in a computer, and if the standard tile signal differs from the prescribed information, the microcomputer adjusts the fluorescent lamp drive until the signal from the standard tile reaches the prescribed level, at which time the color signals from the test sample are evaluated while the lamp intensity and camera response are generating standardized measurement conditions.

Assignee:

Interface Solutions, Inc. - Lancaster PA

International Classification:

F02F 1100
F16J 1508

US Classification:

277592

Abstract:

A gasket which is compression-failure resistant, even at operating flange pressures in the range of from about 3,000 to about 15,000 PSI and also has a good sealing ability, comprises a soft gasket material having two opposed, facial surfaces and an aperture with an edge perpendicular to the facial surfaces, wherein the edge of the aperture has a polymer coating (coating A) on the edge for a good sealing ability. In this embodiment, except for coating A, the gasket is otherwise not coated which makes the gasket compression-failure resistant. In embodiments which need even better sealing ability, at least one of the opposed, facial surfaces has polymer coating B, which may abut both the edge and polymer coating A, wherein polymer coating B on the facial, opposed surface leaves the gasket uncoated for sealing ability in an amount effective to give the gasket compression failure resistance.

International Classification:

B05C 500

US Classification:

427284

Abstract:

A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding. A process for coating the gasket edges which are around the aperture comprises placing the gasket sheets together so that a cavity is formed by the apertures, the sides of the cavity are the aperture edges to be coated. The coating material is put into the cavity and contacts the edges to be coated to form the coated edges.
