    Abstract: A method for establishing by means of heat treatment a weld or glue connection between two mutually adjacent surfaces of components, for instance tubes, using respectively an adhesive material, for instance plastic, more particularly epoxy resin, wherein heat is supplied round or close to the weld surfaces for connecting, wherein in order to measure the correct quantity of supplied heat and prior to the heat supply a test loop (10) is arranged round the weld provided with a temperature-sensitive interrupter (13) and an electric fuse (14) connected in parallel thereto, and after the interrupter has responded as a result of the correct temperature being reached after a predetermined time a current surge is passed through the safety fuse in the loop, so that it is possible to determine precisely whether the welding has been carried out for a sufficiently long time and with sufficient heat.

    Abstract: Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire (2). The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire (2) as it is heated. The feedback mechanism monitors the length of the sealing wire, and adjusts the current applied to the wire, responsive to that monitored length. One end of an electric impulse element such as a seal wire (2) is fixed to the underside of a top jaw (20) with a wire tension block. The opposite moving or floating end of seal wire (2) is coupled to a seal wire pivot member (1) at wire terminal (10). A pivot member (1) is pivotally mounted on the top jaw (20) at pivot point (9) so that it moves in response to expansion and contration of the seal wire (2), depending upon the seal wire temperature. A detector actuator (3) in mounted to the seal wire pivot plate or block (1), and extends beyond the pivot member (1) towards detector (5).
