  • Publication number: 20060207726
    Abstract: A resin impregnated cured in place liner having an everted outer impermeable coating is provided. A roll of a continuous length of resin impregnable material is formed into a tube. An impermeable film or wrapping is formed into a tube about a tubular former, sealed and continuously everted about the inner tubular member travelling in an opposite direction so that the everted wrapping envelopes the inner tubular member. Alternatively, the inner tubular member may be passed into a stuffer tube having an impermeable tube thereon that is everted onto the moving tubular member to encapsulate the inner tubular member. The inner tubular member may be passed through an open resin impregnation tank to impregnate the impregnable material prior to everting the outer layer thereon. The inner tubular member may have an inner layer of impermeable material bonded thereto. It may be formed into a tube with the impermeable layer on the outside and continuously everted to place the impermeable layer on the inside of the tube.

  • Patent number: 7108456
    Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The bladder is stored in a pressure bladder canister coupled to a pressurized downtube and eversion elbow. The bladder is everted by introducing pressurized air into the canister As the bladder reaches the distal manhole, it enters a receiving canister where it is punctured while maintaining air pressure within the bladder a pinch valve between the downtube and elbow isolates the inverted bladder so that steam can be introduced into the bladder to cure the resin and exhaust through the receiving canister. The bladder is then removed and lateral service reinstated.

  • Patent number: 7071783
    Abstract: An amplifier circuit for amplifying radio frequency signals having temperature compensation and bias compensation includes a radio frequency power amplifier that receives an input radio frequency signal and outputs an amplified radio frequency signal, and a first transistor performing as a detector diode with its collector and base connected. The base of the first transistor receives the amplified radio frequency signal from the power amplifier, a second DC bias input signal from a regulated DC source, and a third power-sensing signal. The amplifier circuit further includes a second transistor to amplify the DC component of the RF signal from the base of the first transistor. The base of the second transistor is coupled to the base of the first transistor. The collector of the second transistor outputs the power-sensing signal, which is coupled to the regulated DC source through a resistor.

  • Publication number: 20060130753
    Abstract: A resin impregnation tower for continuously impregnating the resin impregnable layer of a tubular cured in place liner is provided. The tower is of a height to provide sufficient resin pressure head to impregnate the resin impregnable layer fully. A cured in place liner having at least one layer of resin impregnable material is fed into the top of the tower, drawn down about a roller at the bottom, removed from the top of the tower and then wrapped with an outer impermeable coating. The impregnated liner is suitable for pull-in-and-inflate method of installation or may be inverted. For liners formed with an inner impermeable layer, the liner is suitable for curing with steam.

  • Publication number: 20060090804
    Abstract: A process for lining an existing pipeline or conduit with a flexible resin impregnated cured in place liner by pulling in the liner and inflating a resin impregnated inflation bladder with air and curing the liner with flow-through steam without loss of pressure is provided. The liner includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer. The inflation bladder also includes a resin absorbent material in tubular form with an impermeable membrane forming an outer layer and an exhaust assembly at the trailing end and is passed through a pressurized inversion apparatus into the collapsed liner. As the bladder reaches the distal end, the exhaust assembly exits the everting bladder and is coupled to an exhaust hose. Steam is then introduced the inversion apparatus to cure the resin and is exhausted through the exhaust tube. After cure, steam is replaced with air to cool the liner and the ends are cut to restore service through the host pipe.
