Abstract: The object of the invention is to provide a method which is as simple and economical as possible for manufacturing a tufted product, in particular a tufted top layer of a carpet, having improved nep adhesion properties. For this purpose splittable fibers are used which split on or in the region of the puncture site during tufting.

Abstract: A dynamic seal provides for the return of captured lubricant to the lubricant side regardless of the direction of rotation between the seal and the shaft. The seal uses bi-directional pumping elements to facilitate the hydrodynamic pumping of the captured lubricant in response to relative rotation. The seal includes a valve portion that can change a pumping rate of particular pumping elements such that more lubricant is pumped toward the lubricant side than the non-lubricant side.

Abstract: An improved air exhauster for a vehicle is provided, comprising a non-woven filter with a covering sheet of material fastened to the filter face. The filter may be assembled into a frame and the covering sheet may acts as valve to allow air outflow from the interior of the vehicle, yet restrict outside noise from entering. The covering sheet may be a relatively more dense non-woven material than the filter or may be a polymer film. The covering sheet may be attached at the centerline of the filter to function as a pleat separator and reduce the incidence of pleat collapse under high flow rate or increased pressure drop.

Abstract: A radial shaft seal is provided for accommodating large radial offset of the shaft relative to a housing. The seal includes an annular retainer insert provided for engaging the seal to a fixed housing. An annular elastomeric seal body is molded to the retainer insert and includes flexible axially extending portion extending from an inner surface of the retainer insert. A seal portion extends axially from a radially inward end of the radially inwardly extending portion and includes a seal lip with a garter spring disposed radially outward of the sealing lip and an elastomeric bearing surface disposed adjacent to the sealing lip. The bearing surface includes a plurality of raised pads adapted to engage the shaft. The pads each include a rounded edge on lateral sides thereof for encouraging the creation of a lubricating film between the pads and shaft. The pads are lubricated by direct exposure to the fluid being sealed.

Abstract: A dynamic shaft seal assembly is provided including a dynamic seal for engaging a rotary shaft. The dynamic seal includes a base portion that is mounted within a casing and has an axially extending barrel portion extending from a radially inner end of the base portion. The axially extending barrel portion terminates in a radially extending leg portion which extends inwardly from an end of the axially extending portion. A generally conically shaped seal portion extends from an end of the radially extending portion and the seal portion includes a radially inner face engaging the shaft and a radially outer face having a stiffening bead integrally formed thereon. The stiffening bead reduces the seal's propensity for “bell mouthing” while the axially extending barrel portion provides improved shaft followability for the dynamic seal.

Abstract: A valve stem seal including a radially outwardly extending flange that includes one or more circumferential grooves to allow the flange to flex and lay flat against a support surface and protect the flange from fatigue.

Abstract: A method for forming a textile fusible sheet material includes producing a fibrous web from fibers on a laydown apparatus so as to form a backing ply and applying a mixture of a binder and a thermoplastic polymer to selected areal regions of the fibrous web. The method further includes thermally treating the fibrous web so as to dry and bond the fibers of the fibrous web using the binder to form a bonded fibrous web nonwoven fabric and so as to sinter the thermoplastic polymer with a surface of the bonded fibrous web nonwoven fabric.

Abstract: A valve assembly disposable in a turbocharger housing includes a cover; a sealing body connected to the cover so as to form a pressure space between the cover and the sealing body; a restoring spring disposed in the pressure space and disposed against the cover and the sealing body, wherein the sealing body is moveable relative to the cover counter to the force of the restoring spring; and a diaphragm connecting the cover and the sealing body to each other, wherein the diaphragm at least partly surrounds the sealing body.

Abstract: A gasket includes a damping buffer (1) for a piston (2) that can be charged with a pressure medium and that can be moved back and forth axially in a cylinder pipe (3) and includes at least one static seal (4) for sealing the cylinder pipe (3) vis-à-vis a cover (5) connected to the face of the cylinder pipe (3) and a dynamic seal (6) having at least one dynamically loaded sealing lip (7) that, during the proper use of the gasket, can be laid against the surface (8) to be sealed of a damping journal (9) that is connected to and axially movable back and forth with the piston (2) and that has at least one flow-guiding connection opening (10) that connects the axial faces (11, 12) of the gasket.

Abstract: A battery includes at least two sealing frames and at least one cell. The sealing frames include a base body defining an opening wherein the base body includes a first sealing surface embodied to be elastically compressible and positioned against opposite sides of a tapered area of the at least one cell.

Abstract: Sealing frame (1) for utilization in a battery, encompassing a base body (2) whereby the base body (2) encompasses an opening (3), whereby the base body (2) features a first sealing surface (4) and a facing second sealing surface (5) and whereby the first sealing surface (4) and/or the second sealing surface (5) are implemented elastically compressible.

Abstract: A gasket for a valve in an internal combustion engine is provided with a support element having a tubular configuration according to an axis and coaxially mounted on the valve. An elastically deformable element is interposed between the support element and the valve. The support element includes a first portion elongated according to the above mentioned axis, and a second portion extending from the first portion in a direction transversal to the axis, at least partially housed in an annular seat of the elastically deformable element and having its radially outermost end connected to the first portion itself. The support element comprises a third portion extending from the radially innermost end of the second portion and folded on the second portion itself so as to generate, in the folding area, a rounded edge cooperating with the annular seat of the elastically deformable element.

Abstract: Polymeric binder blended from thermoplastic and uncured elastomer binds magnetizable particulate in segmentally magnetizable materials used for encoder targets used in encoders and assemblies where encoders determine rate of motion. The polymeric binder has a dynamic mechanical thermal analyzer tangent delta value (ASTM E 1640-94) not greater than 0.1 at a temperature not less than the liquefaction supra point temperature of the thermoplastic when cured with radiation (preferably electron beam radiation) prior to being blended with either the magnetizable particulate or with other filler materials. The binder effects encoder targets evidencing robustness to thermal or chemical agent stress. Pre-cured blends of magnetizable particulate in the binder evidence good extrusion (pultrusion) performance.

Abstract: The present invention provides a sealing ring having at least eight sealing edges. Sealing rings, such as O-ring seals, are generally known. These universal sealing rings can be used for statically or dynamically sealing machine elements. They have the advantage of being suited for a wide variety of possible applications, and of being simple and cost-effective to manufacture.
