Abstract: A locking insert 4 for joining the male and female ends of spheroidal-graphite cast-iron pipes conveying fluids under pressure has a generally planar shape, and includes at least two metal parts 4A, 4B fixed to each other by an electrically insulating junction layer 4C.

Abstract: A metal laminate gasket of the invention is used for an internal combustion engine. The gasket includes a main portion formed of at least two outer metal plates extending substantially throughout an entire area of the engine, a device for defining a first hole corresponding to a hole of the engine, and a coating applied onto a part of the defining device and one of the outer surfaces of the metal plates. The defining device are attached to the outer metal plates and has a plurality of dents near the first hole to surround the same. The coating is filled in the dents to cover a substantial area of the outer surface. Therefore, the coating does not substantially flow to thereby improve sealing around the first hole.

Abstract: A sealing ring inserted into the radial space between two relatively movable cylindrical surfaces of a first and a second machine part. The cylindrical surfaces surround one another coaxially, and the sealing ring includes a first device for statically stationary fixing and sealing of the first machine part, as well as a second device for movable sealing of the second machine part. The first device is formed by a retaining ring made of a polymeric material pierced by at least one relief groove and engaging the first machine part, as well as an annular lip seal situated in front of the relief groove which is acted upon by the pressure of the medium to be sealed. The lip seal elastically deforms above a preselected minimum pressure differential and disengages from the first machine part.

Abstract: A seal for use with a constant velocity joint and a transmission output component. The seal comprising a main seal body having a central axis of rotation, the main seal body including an inner wall and an outer wall and opposing first and second sides. The inner wall defining a connecting region having a generally cylindrical portion for connecting the seal to the transmission output component. A raised rib extending out from the first side of the seal, the raised rib being axially deformable in such a manner as to create an axial force parallel the axis of rotation for reducing the axial slip between the constant velocity joint and the transmission output component and a flange seal portion extending out away from the outer wall, the flange having an inner contacting surface adapts to contact the constant velocity joint and define a protective seal between the constant velocity joint and the transmission output component.

Abstract: A method and apparatus for reducing the wear within a mechanical apparatus having first and second adjacent, sealable surfaces which move relative to each other and having a seal between them.

Abstract: A gasket for sealing between two opposed surfaces with a rigid carrier to which a flexible sealing element is bonded includes at least two carrier members. The carrier members define continuous circumferentially closed inner and outer peripheries. A first carrier member has a first overlapping portion at a first end and a second overlapping portion at a second end. A second carrier member has a first overlapping portion at a first end and a second overlapping portion at a second end. The second overlapping portion of the first member is overlapped by the first overlapping portion of the second member.

Abstract: A shaft seal ring as well as a method and a device of manufacturing same.A shaft seal ring made of a PTFE compound comprises a sealing lip and a protective lip integrally formed therewith, wherein the sealing lip as well as the protective lip are provided with wavy recesses embossed during a manufacturing step.

Abstract: A liquid seal unit having a seal ring with an annular end face cooperating with a seal mating ring on an associated component to form a liquid-tight dynamic seal. A composite multi-functional member with a flexible finger spring embedded in a unitary elastomeric body urges the seal ring and the mating ring together. The spring has an annular continuous outer body portion and a plurality of circumferentially spaced apart, radially inwardly extending flexible spring fingers. The unitary elastomeric body includes a radially outer mounting collar with a generally radially inwardly directed inner surface, a web portion extending radially inwardly from the outer collar and enclosing the flexible finger spring. The body also includes radially spaced, first and second annular load bearing formations that lie in axially opposite directions. The elastomeric body still further includes an axially extending sealing ring positioning collar engaging the seal ring to provide a secondary seal.

Abstract: A flush glass window molding for an automotive vehicle has a hollow triangular shaped portion for filling the gap created between an edge of a window panel and the vehicle body panel, a flexible finger located adjacent to a body-side leg of the triangular shaped portion and extending from the apex thereof, and a substantially flat base extending outward at a generally right angle from the apex of the window-side triangular leg. Furthermore, an outside surface of the window molding base is affixed to the inside of the window panel by a pressure sensitive adhesive tape and an inside surface of the base is affixed to a flange of the vehicle body panel by a urethane adhesive bead.

Abstract: A sealing gasket for a segmented pipe coupling includes radially extending, axially spaced sealing lips interconnected by an axially extending bridge member which has at least one aperture extending through the bridge member in a radial direction, a tubular collar being received within the aperture, the tubular collar being fast with an arcuate elongate plate, the longitudinal edges of which are engaged with mutually presented surfaces of the sealing lips.

Abstract: In a catalytic assembly having an oxidation catalytic unit disposed above the broiling area of a fat-food broiler for enabling the catalytic oxidation of volatile broiling smoke organic contaminants, a low pressure drop open-pore metallic flame-arresting filter screen disposed between the broiling area and the catalytic unit and substantially completely overlying the broiling area and containing upon the screen an adherent coating comprising a high surface area inorganic oxide adsorbent and an inorganic binder therefor, the coating serving to adhere salt, phosphorous and other catalyst-poisoning compounds in the broiling emissions. Preferred methods of coating and broiler flame-arresting use are described.
