A piston head for a syringe pump comprises a barrier portion (11) for driving fluid through a syringe pump barrel (30), wherein a peripheral section (13,14) of the barrier portion (11) is shaped to seal against the syringe pump barrel (30); and a re-silent member (15) arranged to resist deformation of the shaped peripheral section (13,14) of the barrier portion (11).

A sealing profile for embedding into a moulding of curable material, in particular a concrete or plastic moulding, and to a sealing arrangement comprising such a sealing profile. The object of the present invention is to provide a sealing profile for embedding into a moulding of curable material that can be anchored into the moulding in particular such that displacements of the seal in its seat occur to a significantly lesser extent, if at all, when installing or assembling the mouldings. The object is achieved by a sealing profile (1) with a profile region (2) having a profile region surface (4) which is directed towards the moulding (3) after embedding the sealing profile (1), wherein the profile region (2) has, at least in one subregion (6), a non-woven, felted or random fibre layer (5) which is fixedly connected to the sealing profile (1) and which extend beyond the profile region surface (4).

A pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male pipe end to form a plastic pipe joint. The raceway in the female bell plastic pipe end is preformed during manufacture and the gasket is installed thereafter. The gasket has a rubber body portion which is reinforced by a hard plastic band formed as a series of integral, spaced wedges which are interconnected by a flexible ribbon. The gasket is flexible enough to be flexed and placed in the pipe raceway and yet the hard plastic band acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.

This invention provides: a method for manufacturing a supercharger compressor housing, in which a supercharger compressor housing is manufactured through at least a local heating step for locally heating an area to be heated, which is part of an abradable seal, and a mounting/fixing step for mounting and fixing the abradable seal to a mounting/fixing surface of a compressor housing main body, the locally heated area to be heated being inserted while being deformed into groove parts provided to the mounting/fixing surface in the mounting/fixing step; and a compressor housing created using this manufacturing method.

A method for forming seals on seal carriers, in particular vehicle doors or vehicle door frames, extrudes a sealing material strand which is to be processed to form a multiplicity of seals and has a cavity, coils or folds up the sealing material strand, forming a transportable unit that is transported to a processing site and the sealing material strand is fed continuously to a processing device by being drawn out of the transportable unit. During the processing, a section of the sealing material strand that is to be applied to the relevant seal carrier and forms the seal is in each case severed from the sealing material strand. In each case during or after the processing of the sealing material strand to form a seal, that section of the sealing material strand which forms the seal is reinforced in places at least at one predetermined longitudinal position of the section by introducing material into the cavity.

The present invention improves the handling properties of a rubber-only gasket and the affixability thereof to an attachment position. To this end, the provided gasket is: obtained by combining a gasket body of the rubber-only type, and a carrier sheet that comprises a resin film and holds the gasket body in an un-adhered state; and characterized in that the gasket body is provided with an adhesive section or bonding section for adhering or bonding the gasket body to an attachment position when attaching the gasket body to the attachment position. The adhesive section or bonding section is prepared by providing the lateral surface of the gasket body with a projecting section, and coating the surface of the projecting section with an adhesive or bonding agent. The gasket body is to be used as a gasket for a fuel cell to be incorporated into a fuel cell stack.

A sealing profile receiving device having first and second holding units for receiving and holding first and second sealing profile elements, and a casting unit for casting a connecting portion for connecting the first and second sealing profile elements and/or for casting first and second end terminations of the first and second sealing profile elements. A first and/or second and/or third drive unit for driving at least one holding and/or clamping and/or ejector element is/are provided and includes a chain comprising a plurality of chain links arranged at least between two guide faces of a guide unit for guiding the chain and/or chain links, such that an adjusting force can be exerted in the pulling and pushing directions of the chain by the first and/or second and/or third drive unit.

The disclosure relates to additively manufactured (AM) composite structures such as panels for use in transport structures or other mechanized assemblies. An AM core may be optimized for an intended application of a panel. In various embodiments, one or more values such as strength, stiffness, density, energy absorption, ductility, etc. may be optimized in a single AM core to vary across the AM core in one or more directions for supporting expected load conditions. In an embodiment, the expected load conditions may include forces applied to the AM core or corresponding panel from different directions in up to three dimensions. Where the structure is a panel, face sheets may be affixed to respective sides of the core. The AM core may be a custom honeycomb structure. In other embodiments, the face sheets may have custom 3-D profiles formed traditionally or through additive manufacturing to enable structural panels with complex profiles. The AM core may include a protrusion to provide fixturing features to enable external connections. In other embodiments, inserts, fasteners, or internal channels may be co-printed with the core. In still other embodiments, the AM core may be used in a composite structure such as, for example a rotor blade or a vehicle component.

Modified diene polymers containing heteroatoms are disclosed, as is their production, rubber mixtures comprising these modified diene rubbers, and to their use for the production of rubber vulcanizates, which serve, in particular, for the production of rubber moldings and the production of tires.

A method of manufacturing a composite annular seal for a semiconductor process chamber is provided. The method includes extruding a first elastomeric material in uncured form to form a cord of uncured first elastomeric material and extruding, via crosshead extrusion, a second elastomeric material in uncured form onto an outer surface of the cord of uncured first elastomeric material to form an uncured radially layered cord. The uncured radially layered cord includes an inner core of the first elastomeric material and an outer layer of the second elastomeric material. The second elastomeric material is different than the first elastomeric material. The method also includes co-curing the first and second elastomeric material of the uncured radially layered cord to form a cured radially layered cord. The method also includes splicing, via hot vulcanization, a first and second end of the cured radially layered cord to form the composite annular seal.
