  • Method and apparatus for installing a replacement pipe
    Patent number: 6102624
    Abstract: A replacement pipe is installed within an existing service pipe (1) by first advancing a sealing means (6,8) along the existing pipe to a position adjacent its junction with a main pipe (2), then deploying the sealing means to seal against the inner surface of the existing pipe) in the example shown, by pumping sealant (10) into the space between the seal body (6) and the pipe (1), and subsequently advancing the replacement pipe along the existing pipe. The space between the two pipes is then filled with sealant and finally the sealing means is opened, in the example shown by withdrawing a guide rod (5) and its collar (7) on which the sealing means was advanced into position.

  • Faulty sewing detector
    Patent number: 6095071
    Abstract: Provided is a faulty sewing detector that is, for example, mounted on an overlock sewing machine, with which an over-edge chain stitch is made in a state in which a body fabric and a sleeve fabric of a T shirt or underwear are overlapped with each other. The detector comprises a fabric twisting detecting sensor that detects a fabric twisting by determining the number of overlap of fabrics sewed which is disposed at a position corresponding to the fabric sewing area of a needle, and, behind a needle location in a sewing direction; a faulty sewing judging means that compares a fabric twisting quantity detected by the sensor, with a preset permissible fabric twisting quantity, to judge it as faulty sewing when the former exceeds the latter; and an informing means that is activated when judged as faulty sewing.
