Detachable seal for medical implants
A medical implant includes a first component having a surface and a plurality of electrical contacts and a second component having a surface and a plurality of electrical contacts. Each contact of the first component contacts an assigned contact of the second component in an electrically conducting manner. A seal is disposed between the two surfaces for sealing the contacts. The seal and the two surfaces are formed of a thermoplastic material. The seal is fused to the two surfaces for sealing the contacts and the seal is meltable so as to separate the two components from one another. A method for producing a medical implant is also provided.
WELDABLE CONNECTING ELEMENT FOR CONNECTING OR JOINING THERMOPLATIC LINE ELEMENTS, AND A WELDING ASSEMBLY AND A METHOD FOR PRODUCING A WELDED CONNECTION
The invention relates to a weldable connecting element 2 for connecting or joining thermo-plastic line elements 3. The connecting element 2 comprises: a thermoplastic body 4; at least one heating element 6, which is embedded in the body 4, wherein the heating element 6 serves to generate heat in a welding area 5 for welding the body 4 to the at least one line element 3. Furthermore, a joining control 12 is provided, which is configured to prohibit the welding operation and/or to interrupt the welding operation if the body 4 and the line element 3 are not joined correctly.
Apparatus and method for electrofusion welding of reinforced thermosetting resin pipe joints
A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; and a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe. The first pipe and the second pipe are made from a reinforced thermosetting resin (RTR). The coupler comprising a resistive element implanted therein and connected to electrodes extending to an exterior of the coupler. A thermoplastic material is disposed between an exterior of the first pipe and an interior of the coupler. A thermoplastic material is disposed between an exterior of the second pipe and the interior of the coupler. Upon application of electricity to the electrodes, the resistive elements are heated sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler. A method of coupling pipes includes disposing a thermoplastic material between an exterior of a first pipe and an interior of a coupler; disposing a thermoplastic material between an exterior of a second pipe and the interior of the coupler; inserting the first pipe and the second pipe into the coupler; and applying of electricity to electrodes of the coupler such that resistive elements of the coupler heat sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler.

Heating element geometry for use in a tapping saddle
A tapping saddle for a plastic main pipe carrying a medium includes a stub having a central axis, a saddle piece, and a drill. The drill is configured to be moved axially in the stub. A heating element geometry, which is used for welding the tapping saddle to a main tube outer circumference, is arranged on an inside diameter of the saddle piece. The heating element geometry has a winding having an outer winding region and an inner winding region. In the inner winding region, the winding extends in meandering loops along a circle concentric with the central axis of the stub.
