  • Rotary cylinder configuration and method to control slot dimensions during direct weld attachment to the shell
    Patent number: 4790733
    Abstract: A rotary cylinder is tested by loading in two fixed and one movable locations until a location of the movable point is found at which no, or a predetermined amount of, distortion takes place in the vane slot. The cylinder is then welded into a shell at the three points without producing distortion of the vane slot or with a predetermined distortion.
