Modular molding
A tubing including an overmold is connected to a fitting by welding the overmold to the fitting. Methods for doing the same are also provided. Also provided are methods for forming an overmold on a tubing or on a tubing and fitting assembly.
Molded hose with fabric layer
A reinforced hose includes an inner layer, a reinforcing intermediate layer, and an outer layer. The inner layer has and inwardly projecting sealing rib extending circumferentially on an inner surface thereof. The inner surface may also have an end stop to be engaged by a fitting received in the hose. The outer layer has a pair of annular clamp guides projecting outwardly which are axially spaced from an end of the hose. The sealing rib is positioned between the clamp guides to indicate an optimum location for a hose clamp.
Methods and apparatus for plugging cells of ceramic structures and honeycomb filters
A method for plugging a subset of cells of a honeycomb structure that includes: covering a first end face of the honeycomb structure with a mask that comprises a body and a plurality of openings, wherein the plurality of openings of the mask is coincident with a plurality of cells of the honeycomb structure; providing a plug of material upon a film material; applying a force to the film material to push the plug of material through the plurality of openings of the mask and into the plurality of cells of the honeycomb structure; and measuring a pressure within the plurality of cells during the applying step, wherein the applying step further comprises adjusting the force applied to the film material based at least in part on the pressure within the plurality of cells to push the plug of material to a predetermined depth within the plurality of cells.
Apparatus and methods for sealing a vascular puncture
A sealant for sealing a puncture through tissue includes a first section, e.g., formed from freeze-dried hydrogel, and a second section extending from the distal end. The second section may be formed from PEG-precursors including PEG-ester and PEG-amine, e.g., in an equivalent ratio of active group sites of PEG-ester/PEG-amine greater than one-to-one, e.g., such that excess esters may provide faster activation upon contact with physiological fluids and enhance adhesion of the sealant within a puncture. At least some of the precursors remain in an unreactive state until exposed to an aqueous physiological environment, e.g., within a puncture, whereupon the precursors undergo in-situ cross-linking to provide adhesion to tissue adjacent the puncture. For example, the PEG-amine precursors may include the free amine form and the salt form. The free amine form at least partially cross-links with the PEG-ester and the salt form remains in the unreactive state in the sealant before introduction into the puncture.
DIE FOR CASTING JUNCTIONS OF A COATING OF A PIPELINE
A die for casting junctions of a coating of a pipeline is configured to be coupled to the pipeline to form an annular shaped closed compartment about a tubular joint portion comprising a tubular wall, which extends about a designated axis; a plurality of centering devices configured to align the axis of the tubular wall with a longitudinal axis of the pipeline; two annular walls arranged respectively at the opposite ends of the tubular wall; and two pluralities of vent openings arranged along the tubular wall respectively at each of the annular walls; and at least one feeding port configured to supply polymer material into the closed compartment.
Tubular with screw thread
The invention relates to an improved filament-reinforced tubular, and a method for providing such a tubular. A filament-reinforced tubular according to the invention comprises a tubular body (2), the tubular body comprising multiple fibre mats (10) encapsulated in a thermoset material (11), and is at least at one end provided with a male screw thread (3) comprising threading. According to the invention, the threading comprises a core member (12, 16). Furthermore, the threading comprises one or more fibre mats (13) that cover the core member. The one or more fibre mats are pulled between the windings of the core member by a positioning wire (14). The core member, the one or more fibre mats, and the positioning wire, are encapsulated by a, preferably thermoset, cover material (15), which cover material defines the shape of the screw thread.
COMPOSITE WHEEL ASSEMBLY AND METHOD OF MANUFACTURING
A composite wheel assembly and method of fabricating the same is provided. The wheel assembly includes a composite wheel rim, a wheel center, and a plurality of attachment fasteners for attaching the wheel center to the wheel rim. The wheel rim includes a plurality of attachment inserts that are configured to selectively engage with respective attachment fasteners. Each attachment insert is encapsulated by a plurality of composite layers of the wheel rim or is otherwise secured to the wheel rim. The attachment inserts extend from and/or are positioned within a drop well region of the wheel rim. The method of fabricating the wheel assembly includes forming first and second preforms and positioning the same onto a mold assembly. The method further includes positioning the attachment inserts between the first and second preforms such that the attachment inserts are secured therebetween.

Apparatus for manufacturing a flanged composite component and methods of manufacturing the same
A method of manufacturing a flanged composite component is provided. The method includes coupling a composite structure to s first composite material. The method includes coupling a second composite material to the composite structure and placing a first expansion device within the composite structure. A forming element is coupled to at least one of the first composite material, the composite structure, and the second composite material against the mold. The method includes coupling a pressure element to the forming element to define a space among the mold, the forming element, and the pressure element. The method includes expanding the first expansion device to impart a force to the second composite material to move the second composite material away from the composite structure and into the space to facilitate forming a first flange.
Open composite shaft
A composite shaft assembly including a core structure formed by weaving fiber(s) into an open composite structure. The assembly further includes a first end piece and a second end piece having helically shaped groove(s) and/or axially groove(s) on an outer surface of an end portion of the first and second end piece.
