An apparatus for inserting a lining material into a pipeline includes an elongated carrier device having a hollow central portion which encloses a liner-bladder assembly. The liner-bladder assembly includes an elongated inflation bladder which engages an open end of the carrier device and expands under fluid pressure out of the carrier device. The pipe liner is frangibly attached to the inflation bladder such that its attachment anchors the liner with respect to the open end of the carrier device to permit accurate placement of the liner within a pipeline proximate to a compromised section of the pipeline. The frangible connection breaks when the carrier device and inflation bladder are removed from the pipeline.

The hot water is stored in the hot-water tank and kept at the predetermined temperature. The clamp base is provided in the hot water of the hot-water tank for receiving the substrate portion of the wafer and the lifter is arranged for moving the wafer from the upper part of the hot-water tank into the hot water. The clamper is placed at the upper of the clamp base and the substrate portion of the wafer is pushed to the clamp base fixedly and the pusher is arranged at the upper side of the clamp base in the vicinity of the clamper so as to push the slice base of the wafer, whereby the slice base is peeled. The peeling is performed in the hot water, therefore, the temperature of the wafer does not lower while peeling, so that the adhesive can be peeled easily.

A thin film bonding method and apparatus having structure for removing wetting agents applied to a thin film and base plate that are to be bonded by pressure and heat. A spray or rollers apply the wetting agent prior to the initial bonding of a leading edge of the thin film to a leading edge of the base plate. A pressure roller applies heat and pressure to the film and base plate, bonding them together as the roller rotates and drives the plate toward a cleaning position. Suction and agent removal rollers are used to remove the residual excess agent from the bonded film and the pressure roller. The removal rollers are joined together by a link mechanism that has a spring bias and is operation by a gear mechanism that provides a wiping action.

A protective coating on a pipe is embrittled by enclosing a portion of the pipe in a body defining an annular space around the protective coating. A pressurized LN2 cryogen is expanded within this annular space for sufficient time to lower the temperature of both the protective coating and the underlying pipe to a temperature below the temperature of embrittlement of the coating. The LN2 is expanded so as to form elliptical patterns on the pipe surface.

Web-splicing apparatus comprises a web splicer and, associated therewith, an air mover and web-presentation means operable to present to the inlet end of the air mover the leading end of a first web extending from a reel and the leading end of a second web extending from another reel, which air mover is operable to feed the leading end of said first web from said presentation means to and through a splicing zone, to serve as a guide for subsequent continuous passage of that web and further operable to feed the leading end of the second said web from said presentation means to said splicing zone during continuous passage of the first web through the air mover. Web-severing means may be disposed for operation in the splicing zone and web-withdrawal means, suitably further air-mover means, downstream of that zone. Splicing-patch supply means comprises a continuous backing strip carrying spaced adhesive patches, means for advancing the said strip past patch-detachment means, a movable vacuum-supplied holding element for receiving detached said patches, and a vacuum-supplied stationary element on the side of the web path remote from said movable element, a detached patch being pressable onto a web by movement of the first-named element towards the second-named element.

Disclosed is apparatus for stripping and cleaning a backing plate, such as, an arcuate press saddle, by the process of rotating the saddle past a blade to strip a pinging plate therefrom by advancing from a corner diagonally with respect to movement of the saddle, through a bath of adhesive-removing solvent to wash the stripped saddle surface, into contact with a rotating brush to remove solvent and adhesive from the washed saddle surface, and through an airstream to dry the cleaned saddle surface.

A processing apparatus of a stack is provided. The stack includes two substrates attached to each other with a gap provided between their end portions. The processing apparatus includes a fixing mechanism that fixes part of the stack, a plurality of adsorption jigs that fix an outer peripheral edge of one of the substrates of the stack, and a wedge-shaped jig that is inserted into a corner of the stack. The plurality of adsorption jigs include a mechanism that allows the adsorption jigs to move separately in a vertical direction and a horizontal direction. The processing apparatus further includes a sensor sensing a position of the gap between the end portion in the stack. A tip of the wedge-shaped jig moves along a chamfer formed on an end surface of the stack. The wedge-shaped jig is inserted into the gap between the end portions in the stack.

A device for forming a separation starting point that allows separation of a surface layer of a processed member to form a remaining portion is provided. A manufacturing device of a stack including a support and a remaining portion of a processed member whose surface layer is separated is provided. The device for forming the separation starting point includes a stage that supports the processed member, a cutter that faces the stage, a head portion that supports the cutter, an arm portion that supports the head portion, and a moving mechanism that relatively moves the cutter to the stage.

Methods and tools for de-bonding and cleaning substrates are disclosed. A method includes de-bonding a surface of a first substrate from a second substrate, and after de-bonding, cleaning the surface of the first substrate. The cleaning comprises physically contacting a cleaning mechanism to the surface of the first substrate. A tool includes a de-bonding module and a cleaning module. The de-bonding module comprises a first chuck, a radiation source configured to emit radiation toward the first chuck, and a first robot arm having a vacuum system. The vacuum system is configured to secure and remove a substrate from the first chuck. The cleaning module comprises a second chuck, a spray nozzle configured to spray a fluid toward the second chuck, and a second robot arm having a cleaning device configured to physically contact the cleaning device to a substrate on the second chuck.
