The present invention relates to a method for rehabilitating lines, in particular sewers, shafts or the like, a curing device being activated or having been activated for curing the curable and/or curing ply, and an advancement of the curing device in the lining sleeve and in particular the power output of the curing device being controlled in an open-loop or closed-loop manner in dependence on the temperature sensed by the temperature measuring device on the outer side of the curable ply.

The present invention relates to a system for curing a lining sleeve comprising a curing device with a radiation source, a lining sleeve with a curable ply and an outer film arranged around the curable ply, a measuring device, which is arranged between the curable ply and the outer film and/or on or at a distance outwardly from the outer side of the curable ply, the measuring device being designed and set up to sense a measured value representative of the curing of the curable ply, and also an open-loop or closed-loop control device, which is designed and set up to control the advancement of the curing device in the lining sleeve and/or the power output of the radiation source of the curing device in an open-loop or closed-loop manner in dependence on the measured values sensed by the measuring device on the outer side of the curable ply.

The present invention relates to a device for curing resin-impregnated lining tubes using high-energy radiation, comprising at least two radiation sources for generating high-energy radiation, wherein the device has a front end, a rear end, two oppositely situated side ends, a top end, and a bottom end, wherein a length of the device from the front end to the rear end is smaller in a transport state than in an operating state. At least one element of the device is foldably, displaceably, rotatably, and/or movably supported, and at least one first radiation source is situated farther from at least one additional radiation source in the operating state than in the transport state. The device includes a fastening point on which a tensile force can act, in particular in the longitudinal direction of the device in order to transfer the device from the transport state into the operating state.

A spin fastening system includes a first member and an adhesive layer applied to the first member. A second member is positioned in contact with the adhesive layer. At least a portion of the adhesive layer is cured after the second member is positioned in contact with the adhesive layer to render at least the portion of the adhesive layer substantially rigid. At least one spin fastener is inserted successively through each of the second member, the cured portion of the adhesive layer, and the first member.

Injection-compression molding apparatus and methods to form a lens in a mold insert by an injecting a polymer into an internal cavity of the mold insert until a pressure of the internal cavity exceeds a predetermined force value, the first mold side being fixed and the second mold side being moveable and configured to apply a force generating the internal cavity pressure. The method includes controlling a first temperature of the first mold side to be in a range of 4 degrees Fahrenheit to 10 degrees Fahrenheit greater than a second temperature of the second mold side and controlling a coining compression distance of the second mold side to be in a range of 0.008 inches to 0.018 inches.

An apparatus and method for heating a material are disclosed. The apparatus includes one or more magnetron assemblies positioned on each of opposing sides of a heating region. The magnetron assemblies positioned on one side of the heating region generate overlapping microwaves that propagate in a first direction through the material, and the magnetron assemblies positioned on the other side of the heating region generate overlapping microwaves that propagate in a second direction through the material. The overlapping microwaves provide a total wave voltage that is substantially constant across the material resulting in substantially even heating of the material.
