Controlled translation method of affixing a termination to a tensile member
09840044 · 2017-12-12 ·

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

Electrofusion of pipe liners
11674631 · 2023-06-13 · ·

A method of joining together liner sections within a polymer-lined pipe energises an induction coil inside the pipe to spot-heat part of a circumferential interface between the liner sections. This melts and fuses the polymer material locally. The induction coil is then moved along the interface to heat other parts of the interface successively above the melting temperature. An apparatus for performing the method has a power supply for energising the induction coil and a drive system for moving the energised induction coil relative to a body of the apparatus. The apparatus may be configured as a carriage that is movable along the pipe.

11673348 · 2023-06-13 · ·

A sensorless temperature sensing and control system and method uses electrical voltage and current feedback signals to monitor and control the temperature of heating elements used in a heat sealing process wherein sensors are not physically connected to a heat seal bar during the heat sealing process. After calibration of a heat seal bar using a sensor, voltage and current feedback signals are processed by a programmable logic controller (PLC) to calculate the real-time electrical resistance of each heating element. Data and electrical resistance is used to calculate real-time temperature of the heat seal bar during heating.
