A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve sear and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

A novel collapsible plant support includes a collapsible coil adapted to rest on a flat surface. In a particular embodiment, the collapsible plant support includes a plurality of vertical support structures coupled to the collapsible coil so as to provide additional support. In another particular embodiment, a collapsible plant support includes plant receptacle receiving element that supports both a collapsible coil and also a plant receptacle. In a more particular embodiment, the plant receptacle receiving element includes fluid ducts for connecting multiple plant receptacle receiving elements into a fluid network. In another embodiment, the coil is disposed within a helical sleeve coupled to a flexible, cylindrical mesh.

A method and apparatus are for coating a field joint of a pipeline. The method includes positioning a mold tool around the field joint to define a mold cavity, positioning an insert to lie within the mold cavity, and injecting plastics material into the mold cavity to embed the insert in the plastics material. The apparatus has a mold tool positionable around the field joint to define a mold cavity, and an insert positionable within the mold cavity to be embedded in plastics material injected into the mold cavity. Use of an insert in this way reduces the volume of the molten thermoplastics material required to coat the field joint, thereby increasing the interface area of the melt relative to its volume, to the benefit of cooling time.

A fuel tank including a built-in component is provided. The built-in component includes: a carrier part being a rigid body including a plurality of engaging parts, and a plurality of struts each including an engageable part to be engaged with one of the engaging parts. The engageable part of the strut includes an upper contact surface and a lower contact surface, which are formed spaced apart from each other in a height direction. The engaging parts of the carrier part each includes a biasing part that, when the strut is engaged with the engaging part, enters a space between the upper contact surface and the lower contact surface and generates biasing forces in directions to move the upper contact surface and the lower contact surface away from each other.

A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve seat and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

A structural reinforcement and biocompatible pump head for a pump includes a reinforcement structure having a plurality of ports and fluid pathways therein. The fluid pathways in the reinforcement may be coated or lined with a biocompatible material to form a biocompatible pump head useful for liquid chromatography and other analytical instrument systems. The biocompatible material may be injection molded into the fluid pathways of the reinforcement structure and may be machined after core pins are removed to obtain a desired surface finish and/or size of the biocompatible fluid pathways of the pump head.

A method may include coiling a fiber line around an exterior side of a casing section. A mold may be temporarily secured to at least a portion of the exterior side of the casing section. An epoxy material may be injected into the mold to form a cover. The cover may extend over the fiber line and the exterior of the casing section. The cover may have a substantially equal thickness for centralizing the casing section when the casing section is positioned downhole. The mold may be removed from the exterior side of the casing section after the epoxy material has cured.

In the present invention, a blocking tube (11) has a tubular blocking layer (11a) made of a material having barrier properties, and a tubular covering layer (11b) which is disposed in contact with at least the inner peripheral surface of the blocking layer (11a) and is made of a material of the same quality as a base resin. One end portion of the covering layer (11b) protrudes further toward the outside than an end portion of the blocking layer (11a) which is disposed on the outer periphery side. In the blocking tube (11), the inner peripheral surface of the covering layer (11b) forms the inner surface of a pouring hole (5), and the end face on the one end portion side in an axial direction of the covering layer (11b) and the outer peripheral surface of the covering layer (11b), which protrudes from an end portion in the axial direction of the blocking layer (11a) are embedded in the base resin in contact with the base resin.

In another particular embodiment, a collapsible plant support includes plant receptacle receiving element that supports both a collapsible coil and also a plant receptacle. In a more particular embodiment, the plant receptacle receiving element includes fluid ducts for connecting multiple plant receptacle receiving elements into a fluid network. In another embodiment, the coil is disposed within a helical sleeve coupled to a flexible, cylindrical mesh.

A pressure-medium unit includes a housing, which is produced by injection molding and composed of plastic, in the housing wall of which housing at least one connection bush having a passage opening is fastened, through which pressure medium is fed into and/or led out of the interior of the housing. In the injection molding process of the housing, the connection bush, with the exception of the passage opening, is at least partially injection-molded into the housing wall.
