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.

A fluid transfer assembly (10) for transporting medicinal substances. The fluid transfer assembly includes flexible tubes (14) and a manifold (12) each comprising silicone. The manifold has an inner protrusion (24) and connector portions having (26) inner walls. Free ends of the tubes are inserted into complementary configured inner walls of the connector portions until each of the free ends abut the inner protrusion, which creates a continuous uninterrupted passageway between the inner bores of the tubes through the manifold.

Fitting (1) aus schweissbarem, thermoplastischem Kunststoff mit einem modularen Aufbau, enthaltend mehrere Elemente (2, 3, 9, 10, 11, 12), mindestens ein Hauptelement (2, 9) und mindestens ein Anschlusselement (3, 10, 11, 12), dadurch gekennzeichnet, dass die Elemente (2, 3, 9, 10, 11, 12) rechtwinklig zur Mittelachse (8) verlaufende Stirnflächen (4,5) aufweisen und die Elemente (2, 3,9, 10, 11, 12) ausschliesslich an den Stirnflächen (4, 5) miteinander verschweisst sind.
摘要:
A coupling for joining socket ends of multilayer tubing through electrofusion including a central body having opposing male ends. A core at least partially surrounds the central body and an outer layer encloses the core and central body. The outer layer defines a flange protruding radially outwardly from the central body, wherein the core includes a portion that extends radially outwardly through the flange and out of the flange so that the core can be directly heated by an external heating element.
摘要:
The present invention relates to a method for producing a pipe (1) which is provided in its wall (2) and between its ends with at least one channel (4) which passes through the wall (2), in which method a plastic pipe preform (16) is blow-moulded, wherein a protrusion (17) is provided for the channel (4), this protrusion lining the pipe preform (16) and having inside dimensions which are larger than the outside dimensions of the channel (4), in which method the pipe preform (16) in its as yet unsolidified state is squashed in the region of the protrusion (17) in such a way that a rough channel (21) communicating with the interior (3) of the pipe (1) is formed for the channel (4), this rough channel being closed at its end remote from the interior (3) of the pipe and having, apart from the desired channel length (7), the outside dimension of the channel (4), and in which method the squashed pipe preform (16) in its solidified state is cut in the region of the rough channel (21) in such a way that the channel (4) is then open and has the desired channel length (7).
