A wirelaying apparatus includes a tool arm with a tool head which carries a wirelaying tool. The tool has a cutting tip through which a wire is laid into a working surface of a workpiece. The workpiece is retained in a retainer and is moved relative to the wirelaying tool. In use, the cutting tip follows along an arcuate path while laying the wire into the working surface of the workpiece. Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.

The present invention provides a silicon hose integrated with a sensor port, which includes a base hose and a sensor port. The sensor port includes a sensor connection portion and an embedded portion integrally formed therewith. By embedding the embedded portion in the hose, the sensor port is integrally fixed on an outer circumference of the hose. According to the present invention, it is possible to contribute to a reduction in cost and weight and an improvement in fuel efficiency.

A wirelaying apparatus (2) includes a tool arm (21) with a tool head (22) which carries a wirelaying tool (30). The tool (30) has a cutting tip (31) through which a wire (12) is laid into a working surface (11) of a workpiece (10). The workpiece (10) is retained in a retainer (40) and is moved relative to the wirelaying tool (30). In use, the cutting tip (31) follows along an arcuate path while laying the (10) wire into the working surface (11) of the workpiece (10). Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.

There are a number of applications today where the pumping of abrasive slurries is necessary. The pumping mechanisms, though, can be complex, employing multiple transfer cylinders and movable pipes. These designs have their problems, specifically wear between poorly sealing surfaces. To reduce this problem, seals are provided that have multiple wear surfaces which include harder tiles secured over a softer core to benefit from the relative hardness or flexibility of each of the respective materials.

In a method for manufacturing a socket for connecting a fluid conduit to a container made from thermoplastic synthetic material, wherein the socket has a first socket-shaped material arrangement of at least one layer and a second socket-shaped material arrangement of at least one layer, wherein the first material arrangement is thinner than the second material arrangement and the first and second material arrangements are both made of thermoplastic material at least predominantly and fuse with one another to form a fused joint, the first material arrangement is molded by extrusion or injection molding to a plane film or plate or to a hose. The film or plate is deepdrawn or the hose is blowmolded to a first preform with a socket contour. The second material arrangement is applied onto one side of the first preform in a socket contour by injection molding, coinjection or a monosandwich process.

Low permeation fittings and low permeation plastic containers using same are constructed by molding an outer component into the wall of a plastic container while it is being formed. This causes the opening of a passageway in the outer component to be covered with wall forming material. The inner component is then inserted into the outer component through the wall forming material thereby trapping the wall material between the internal and external components. The barrier layer of the container wall is therefore continuous from the container to inside the fitting. A new fuel container, fuel neck fitting, and flange for mounting components on a fuel tank are disclosed.

An cylindrical convex portion of which opposite ends are open is integrally formed onto a fuel tank made of RDPE therewith so as to inwardly extend in the fuel tank, to provide an opening thereon. A press-fit portion of a filler hose connecting pipe made of PA as a tubular member is press-fitted in the cylindrical convex portion to connecting the tubular member to the fuel tank. At least one annular projection is provided on the outer peripheral surface of the press-fit portion of the tubular member so as to bite in the inner peripheral surface of the cylindrical connvex portion. A face of the annular projection in direction axially of one end of tubular member is formed so as to extend outwardly and inclinedly with respect to the axial direction of the tubular member form one end toward the other end thereof.

A duct coupling pad for joining flexible ducts includes an outer section surrounding a central opening. An adhesive coating is applied to one surface of the coupling pad for adhering the pad to a first one of the ducts to be joined. An opening is formed in the first duct within the area of the central opening of the coupling pad. Securing tabs integrally formed with the outer section of the coupling pad are folded inwardly into the opening in the first duct and adhered to the inner surface thereof. The coupling pad binds the edge of the opening in the first duct to prevent splitting and tearing of the linings. A collar is inserted into the central opening of the coupling pad and the second duct is connected to the collar.
