A thermoplastic engine cover for an internal combustion engine has a plurality of mounting holes for mounting the thermoplastic engine cover to an internal combustion engine. At least two datum locator formed on or arranged on the thermoplastic engine cover. At least one through opening configured to receive a rotatable shaft of the internal combustion engine. The at least one through opening has an internal diameter sized to provide an annular clearance gap between the seal carrier and an adjacent circumferential wall of the at least one through opening, to allow final positioning of the seal in the annular clearance gap to a final position in which the seal and seal carrier are positioned in a dimensionally correct position relative to the at least two datum locators. The seal carrier is then welded to the thermoplastic engine cover.

A method and apparatus for performing an assembly operation. A tool may be macro-positioned relative to an exterior of a fuselage assembly. The tool may be micro-positioned relative to a particular location on the exterior of the fuselage assembly. An end effector is removably associated with an external robotic device associated with an external mobile platform. The tool is removably associated with the end effector. An assembly operation may be performed at the particular location on the panel using the tool.

An additive manufacturing ink composition includes a polysiloxane bearing a plurality of alkenyl groups and a crosslinking agent bearing a plurality of thiol groups. The polysiloxane and the crosslinking agent form an emulsion.

According to one embodiment, a gripping tool includes a gripper. The gripper is flexible. A granular material is provided in an interior of the gripper. The gripping tool grips a workpiece by depressurizing the interior of the gripper in a state in which the gripper is caused to contact the workpiece. The gripper includes a first portion contacting the workpiece, a second portion opposing the first portion, and a fibrous membrane having a plurality of pores and being provided between the first portion and the second portion. A diameter of at least a portion of the pores is smaller than a diameter of the granular material. The granular material is provided between the fibrous membrane and the second portion.

A dual-interface coupler includes a utilities unit, a number of utility cables configured to provide a number of utilities to the utilities unit, a first coupling unit associated with the utilities unit, and a second coupling unit associated with the utilities unit. The first coupling unit is configured to mechanically couple the utilities unit to a first corresponding coupling unit and comprises a utility interface. The number of utilities are configured to flow from the utilities unit through the utilities interface. The second coupling unit is configured to mechanically couple the second coupling unit to a second corresponding coupling unit.

A tubular structure having lobes is produced as a single piece over at least two lobes. Circumferential fibres of the structure have a constant orientation with respect to the longitudinal axis (A) of the structure in any plane (P) transverse to the longitudinal axis. The structure is obtained by weaving or by filament winding.

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the insulation holder and the wire connection ring has contact with the joining component.

An injection mold includes a first mold half with a first mold surface and a second mold half with a second mold surface. The first and second mold surfaces together delimit a cavity when the injection mold is closed. An electrically conductive reinforcing element is arranged on at least one of the first and second mold surfaces and is configured for an electrical voltage to be applied such that the electrically conductive reinforcing element increases in temperature and a viscosity of an injection-molding compound flowing past the electrically conductive reinforcing element decreases. A method for producing injection-mold components using the injection mold includes applying an electrical voltage to the electrically conductive reinforcing element and thereby increasing its temperature such that the viscosity of the injection-molding compound flowing past the electrically conductive reinforcing element decreases as it flows and fills the cavity.

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the insulation holder and the wire connection ring has contact with the joining component.

A system and method for forming a strut. A strut comprises a laminated composite tube having a substantially hollow interior and a pair of longitudinal stiffeners attached to opposite sides of the laminated composite tube.
