  • Apparatus for measuring particulate size without contacting the particulate
    Patent number: 5327217
    Abstract: An apparatus is described for measuring the size of a particulate, without contacting the particulate, and therefore without extra forces on the particulate. Stripped gaps of interference fringes are measured behind the particulate when a monochromatic beam is radiated on the particulate.

  • Method of detecting a broken yarn in a row of line up yarns and apparatus therefor
    Patent number: 4772800
    Abstract: A method and apparatus for detecting a broken line up yarn, wherein a fine beam is adapted to travel widthwise across a row of line up yarns while it is radiated toward the yarns to cause flickerings which are photoelectrically converted to instantly count the current value for the number of yarns. The current value is compared with a standard threshold value, and if the current value is different from the threshold, an alarm signal is emitted indicating an abnormal condition. The present invention can be used as a broken yarn detecting technique for devices dealing with many line up yarns such as a warp knitting machine, a loom, a warping machine and so on.
