A process for forcibly infusing liquid potting compound into the strands of a cable in order to attach an anchor to the cable. The process uses a strand cavity within an anchor that encloses the exposed strands. The strand cavity is sealed. Liquid potting compound is then forced into the strand cavity, where it runs around and through the exposed strands. A second venting passage is preferably employed, so that the liquid potting compound flows through the mold without trapping any substantial air pockets.

A method and apparatus for introducing a sealing compound into a filter device include attaching sealing caps for the purpose of producing the sealing compound, and distributing the sealing compound from a sealing chamber via the sealing caps onto the ends of the filter device. The sealing compound is passed from the sealing chamber into a rotationally symmetrical cantilevered projection of the respective sealing cap, from which the sealing compound penetrates into the housing via corresponding slots of the sealing cap.

A method is disclosed for forming corrosion-resistant joints in a plurality of overlapping thin metal sheet workpieces, at least one of which comprises at least 85% by weight of magnesium sheets. The fastener is a fiber-reinforced polymer rod shaped and sized for insertion into a coaxial opening formed in each sheet and subsequently upset on each end to form a head. The workpiece sheets are deformed to form mechanically-interfering features which cooperatively complement the strength of the fastener, under at least some joint loading patterns. The method may be used for other workpiece and fastener compositions.

The invention concerns a method for manufacturing a shell, in particular a fuselage shell, a wing shell, a horizontal stabilizer shell or a vertical stabilizer shell, that is reinforced with a plurality of stiffening elements, for forming component parts for aircraft with high dimensional stability, wherein the stiffening elements and a shell skin are made with epoxy resin from at least partially cured carbon fiber reinforced semi-finished parts, the method comprising the following steps: positioning the stiffening elements on the shell skin, abutting connecting elements against the shell skin and the stiffening elements, and curing the connecting elements to form the shell. The invention also concerns a shell, in particular a fuselage shell, a wing shell, a horizontal stabilizer shell or a vertical stabilizer shell, manufactured in accordance with the inventive method.
摘要:
Injection bonded articles comprised of a rigid core and secured together with an elastomeric material network which also forms seals and encapsulates at least a portion of the rigid core. The elastomeric material is selected to be compatible with the material comprising the rigid core to create a chemical and mechanical bond therebetween. Injection bonding and over-molding techniques are used to fabricate an electrodeionization apparatus spacer comprised of mated rigid segments secured by a unitary elastomeric material network that also forms internal and external seals that fluidly isolate one or more of inlet ports, resin cavities, and outlet ports as well as throughports. Injection bonding and over-molding techniques can also be used to fabricate other articles comprised of multiple segments.
