IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.

An intake duct for an internal combustion engine includes a tubular wall configuring an intake passage. The wall includes segments that are separate from each other in a circumferential direction of the wall. At least one of the segments is made of a compression-molded fibrous body. Each of the segments includes a flange protruding radially outwards from the wall and having a joint. The joint of the flange of each of the segments and the joint of the flange of the corresponding one of the segments are joined to each other. Each of the flanges includes an opposing surface opposed to the corresponding one of the flanges. The opposing surface is provided with a step portion that is located closer to a proximal side of the flange than to the joint and forms a step in a thickness direction of the flange.

The invention provides methods and apparatus for producing a spirally wound pipe or pipe liner, and also to a web for forming a spirally wound pipe or pipe liner. One aspect of the invention provides a method and an associated machine of winding a helically wound pipe from a web (200) having transversely spaced apart connecting formations (310, 320) adapted to interlock when the web is wound in a helical path and adjacent edge portions (300a. 300b) of the web overlap one another, wherein an exterior support means (400) for the connecting formation at the terminus of the pipe being helically wound from the web is provided, and a radially outwardly directed force is applied against an inner face (220) of the web and the support means (400) to pinch connecting formations into interlocking engagement. A further aspect of the invention provides an elongated web (200) comprising a wall portion (210) bound by edge portions (300a. 300b) and adapted to form a pipe by spirally winding said web and joining adjacent said edge portions, wherein a distal end of joined edge portions (330) of the web projecting from the wall portion (210) of the web is less than a spacing distance defined by a spacer rib (350) projecting from the wall portion, when the web is spirally wound and adjacent edge portions are joined together.

A centrifugal pump impeller in an electromotive centrifugal pump, the impeller including a base body having a bearing to which is attached, on a first end, a permanent-magnetic rotor and, on a second end, a cover disk that is mounted on the base body; and a plurality of pump blades made of first and second parts, the first part being a base blade segment attached to the base body thus forming a first unitary piece and a cover disk blade segment attached to the cover disk thus forming a second unitary piece.

Provided are a resin molded component, a method for producing the resin molded component, and a method for producing a welded resin-molded article which ensure appropriate welding at a portion to be welded, without causing insufficient strength. A resin molded component 1 includes a body portion 10 and a rib 11 integrally molded with each other, the rib 11 protruding from the body portion 10 and configured to be infrared welded to a predetermined resin component 2, the resin molded component 1 having a foamed layer 12 formed at least in the body portion 10. A leading end portion of the rib 11 of the resin molded component 1 has a thinned remainder 11b which has been thinned relative to a root portion of the rib. For example, the rib width of the thinned remainder 11b of the rib 11 is smaller than the rib width of the root portion.

A tooling for fastening metal reinforcement on the leading edge of a turbine engine blade, the tooling including a blade support for receiving a blade while leaving surfaces of the leading edge of the blade disengaged; and a leading edge reinforcement support on which the blade support is designed to be mounted, and including two lateral wedges between which the metal reinforcement for the leading edge of the blade is positioned, the wedges being suitable for being capable of moving towards each other and apart from each other and each of them being provided with a suction grid for gripping the metal reinforcement, the leading edge reinforcement support further including heater elements for polymerizing an adhesive film applied on the leading edge surfaces of the blade.

A method of constructing a large, complex composite panel involves connecting smaller compression molded thermoplastic subpanels, edge to edge using a thermoplastic co-consolidation method. The edges of adjacent subpanels are given complementary surface configurations. The surface configurations are overlapped and heat and pressure are applied to the overlapping surface constructions to co-consolidate the surface constructions in forming a large, composite panel of two or more subpanels.

A vibration welding groove system may include a first component having a joining surface with a groove region, where the groove region comprises a groove formed in the joining surface. The first component includes a base region lacking the groove in the joining surface and a transition region located between the groove region and the base region. The transition region has a tapering of the groove to provide a smooth transition from the groove region to the base region. The vibration welding groove system may further include a second component having a weld leg extending from a main body, where the groove of the first component comprises a shape configured to nudge the weld leg towards a center of the groove during joining of the first component with the second component.

A joint (20) joins a plate member (26) with a preform (22), wherein an inclined part (28), which is inclined relative to a surface that is orthogonal to the direction in which a tensile load is applied to the plate member (26), is formed on a surface (25) that joins with the preform (22). Moreover, an indented part (38) corresponding to the shape of the inclined part (28) is formed on the preform (22) so that the inclined part (28) of the joint (20) is embedded into the indented part (38). The joint (20) is embedded in and bonded to the preform (22).
