  • Patent number: 6966120
    Abstract: A process for determining the alignment of a cylindrical body with respect to a reference direction by means of a measurement device which has a first and a second attachment area and a position measurement probe which is calibrated to the reference direction and is made for detecting a first angle of rotation of the probe around a first axis fixed in space and a second angle of rotation of the probe around a second axis fixed in space. A first measurement and a second measurement is carried out at different areas of the body, the probe being swung in contact with the peripheral surface of the body relative to the first attachment area to measure a characteristic of the first and the second angle of rotation. A comparison of the characteristic of measurements is used to determine the alignment of the body with respect to the reference direction.

  • Patent number: 6854190
    Abstract: A special offset calculator for determining the angle of a pipe fitting. The special offset calculator includes a background sheet having an offset value table with offset values representing various offset distances between two pipes to be connected. A transparent fitting sheet has printed lines which represent center line dimensions of fittings to be used in conjunction with an ell fitting or T-fitting with unknown angle to be determined in order to make the special offset. In use, the fitting sheet is positioned on the background sheet, with designated points on both sheets aligned with each other. After the required offset distance value is found on the background sheet, the fitting sheet is rotated or pivoted until the correct fitting size on the fitting sheet matches the offset distance value on the background sheet.

  • Patent number: 6804897
    Abstract: Apparatus for use in aligning the differential input shaft of a race car with the transmission output shaft includes a transmission attachment and a differential attachment, each of which is detachably mountable to the race car. Each attachment includes a laser mounted centrally in a plate which is mounted substantially perpendicular to the transmission and the differential respectively. The laser mounted to the transmission emits a light beam coaxial to the transmission output shaft and the laser mounted to the differential emits a light beam coaxial to the differential input shaft. By adjusting the differential and transmission relative to each other such that the laser beams do not intersect, the differential and the transmission are aligned for optimum performance. A camber gauge may be substituted for the laser in either plate to measure the attitude of the differential or the transmission.

  • Patent number: 6662457
    Abstract: A method and apparatus for aligning and cutting pipes to extract and install piping in industrial plants is characterized by the use of lasers on a ring for aligning the cutting tool. By adjusting the ring so that beams from the lasers strike specified targets at a remote location corresponding with a pipe end, a cutting location is defined so that the trimmed end of a first pipe will properly align with a remote pipe. When the pipes welded together, their ends will match, thereby minimizing stress in the pipe. A cutting tool can be provided directly on the ring so that the pipe can be cut without removing the ring.
