Abstract:
An elongated, flexible polymer gasket (10) includes a body (30) formed by a length of tubular flexible polymer material, a hollow chamber (36) within the body extending uniformly the length of the body, and a plurality of individual openings (37) spaced apart from one another along the length of the body. The gasket further includes a plurality of individual spring clip fasteners (20), each formed of a metal wire (22), the length of wire being bent to form an elongated, generally planar base portion (24) with opposing major sides (25a, 25b) and an elongated, engagement portion (26) extending transversely away from one of the opposing major sides (25a). The maximum width dimensions (W) of the base and engagement portions (W) being greater than a maximum nominal dimension of the opening whereby the each individual spring clip member is captured in a separate one of the openings with the base portion within the hollow chamber and the engagement portion projecting traversely away from the base portion and the body.
Abstract:
Die Erfindung betrifft einen Ringfiltereinsatz (1) für ein Filter zur Filterung eines fluiden Mediums, insbesondere Luft oder Öl oder Kraftstoff für eine Brennkraftmaschine, wobei der Ringfiltereinsatz (1) zwei Stirnscheiben (11) und einen zwischen diesen angeordneten Filterstoffkörper (10) umfasst, wobei mindestens eine der Stirnscheiben (11) eine Anschlussöffnung (13) aufweist, mit der der Ringfiltereinsatz ( 1 ) auf einen Anschlussstutzen (30) des Filters aufsteckbar ist, und wobei zwischen der Anschlussöffnung (13) und dem Anschlussstutzen (30) wenigstens ein elastisch-flexibler Radialdichtring (20) aus Kunststoff vorgesehen ist.

Abstract:
The present invention relates to compositions and methods for creating insulating seals for use in a variety of applications, and to seals created by such compositions and methods. In particular, the present invention provides novel compositions and methods for creating insulating edge seals that provide multiple contact surfaces. The present invention further provides seals that facilitate attachment of flexible covering materials (such as fabrics, plastics, metals, etc.) to hard surfaces (such as plastics, metals, woods, etc.). The present invention is particularly useful for creating insulating edge seals that provide a means of attachment for removable covers for vehicles (such as tops for automobiles, watercraft, and aircraft), structures, and objects.
Abstract:
A seal device adapted for placement between two flanges is provided comprising an annular seal member having two faces, and inner radius defining a central aperture, and an outer radius defining the radially outer edge of the seal member, a radially inner channel formed between said faces and being open to said central aperture, and a radially outer groove open to the radially outer edge of said seal member, a seal retainer surrounding said seal member and located radially outward therefrom, said seal retainer being sized to engage and extend at least partially into the radially outer groove on said seal member, and a resilient member disposed within said annular seal member between a radially innermost portion of said seal retainer and a radially innermost portion of said groove, wherein said radially innermost portion of said seal retainer contacts and supplies a force to said resilient member.
Abstract:
Improved expanded PTFE materials and improved gasket materials made therefrom, the gaskets being capable of forming a seal with greater bolt load retention than is possible with existing, PTFE gaskets. The expanded PTFE membranes of the invention can be tailored to exhibit a matrix tensile strength in at least one direction of at least 25,000 psi, a matrix tensile strength ratio in two orthogonal directions of between .025 and 4, an orientation index of 50 ° or less, and a density of 2.0 g/cc or less. The improved gaskets exhibit improved mechanical properties such as high bolt load retention, low creep, high tensile strength, low stress to seal and high crystallinity index.
Abstract:
A gasket device (1) for a pipe joint between two pipe ends (9), the device (1) comprising: a gasket (5) for providing a seal between the two pipe ends (9), and a support structure for receiving the gasket (5), wherein the support structure is shaped to engage a pipe end (9) to locate the gasket (5) and acts as a stop to protect the gasket (5) during closing of the pipe joint. By providing a rigid support structure, preferably made of engineering plastics material, together with a soft material (elastomeric) gasket, accurate alignment and location of the gasket can be achieved. Simplified installation of a pipe joint can therefore be effected.
Abstract:
A self-anchoring expansion gap assembly (42) for refractory lined vessels such as a gasifier (10) includes a substantially annular insulating blanket structure (66, 68) formed of compressible refractory material. A coil of rope (62) formed of relatively incompressible refractory material is positioned proximate an outer periphery of the insulating blanket structure. The expansion gap assembly is placed in an expansion gap of a gasifier, for example, such that the coil of rope aligns with an annular channel (30) formed in the refractory lining of the gasifier at the expansion gap. Compression of the expansion gap assembly locks the coil of rope in the annular channel of the expansion gap thereby resisting vacuum pullout. The coil of rope can be formed as a single coil or a plurality of substantially concentric coils preferably from a single length of refractory rope.
Abstract:
A gasket (1) has a gasket core (2) and an outer gasket layer (4) covering the gasket core (2). At least one of the two sealing materials that make up the gasket has two reactive components before they are extruded, with said components chemically reatcting with one another as they are combined and/or extruded. The extruded core may be formed of a two-component resin which is at least one of an elastomer and a foam. The flexible outer layer may be a synthetic resin which is at least one of an elastomer and a foam. The outer layer may be electrically conductive, ultra-violet resistant, or resistant to the environment in which the gasket is to operate. Also taught are methods of apparatus for the manufacture of such gaskets
