A flexible coupling for transmitting torque between parts of a transmission shaft system comprises a tubular section of continuous-fibre-reinforced composite material which has been modified to form a living hinge section with reduced bending stiffness to allow flexion of the tubular section. The tubular section may be modified through the provision of a pattern of formations within the living hinge section. The formations may be in the form of apertures and/or recesses in the continuous-fibre-reinforced composite material to create a plurality of living hinges in the material between, in particular slots and/or grooves.

A high-pressure tank producing apparatus capable of reducing time for increasing temperature of a tank body. The apparatus that heats the tank body with fibers impregnated with a thermosetting resin wound around its surface includes a heating chamber for housing the tank body and a retaining mechanism for retaining the tank body within the heating chamber, in which the heating chamber has an injection port for injecting heated gas onto the surface of the tank body and an exhaust port for discharging the gas to the outside of the heating chamber, the exhaust port being disposed in a position where the injection port is projected in a gas injecting direction, and the retaining mechanism retains the tank body in a region where the injection and exhaust ports overlap with each other as viewed from the gas injecting direction and in a position between the injection and exhaust ports.

A method of installing a liner assembly for pipeline repair or reinforcement includes: pulling a prepared liner assembly into position in the pipeline, the liner assembly including a tubular liner wetted with a curable compound; introducing fluid into the inflatable bladder to bring the tubular liner into firm contact with an interior surface of the pipeline; flowing the fluid continuously through the bladder and discharging the fluid into the pipeline, while maintaining the liner assembly in an inflated condition; measuring a flow rate and a temperature of the fluid entering the bladder; calculating a time period sufficient for the tubular liner to cure based on: an amount of heat required for curing, based on dimensional information of the liner, and the measured flow rate and temperature of the fluid; and maintaining the liner assembly in an inflated condition for the time period sufficient for the tubular liner to cure.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

The invention utilizes temperature sensing to measure the internal temperature of an underground structure, such as a pipe, for the purpose of determining a proper cure interval and/or mix ratio of a resin system during a lining operation. A temperature sensor is placed within a pipe or other underground structure to be rehabilitated and at least one temperature measurement is taken within the structure prior to or simultaneously with the installation of a liner. Once the temperature of an internal aspect of the structure is taken, a cure schedule is utilized to determine the appropriate curing time based on test data obtained from baseline tests performed under simulated conditions in a soil cell apparatus. A computer program may be utilized such that upon entering the type of resin, the lowest recorded temperature of the structure, and the initial resin temperature, a cure schedule is supplied.
