Nonindividual Detector Patents (Class 139/352)
  • Patent number: 6328582
    Abstract: A connector in which the pivoting of a lever to a correct position can be used to detect whether male and female housings are in a fully fitted state. When a lever 30 is pivoted to a correct position, a stopping protrusion 40 fits with a lever stopping member 14 of a female housing 10, thereby causing the female housing 10 and a male housing 20 to fit completely together. When the lever 30 reaches the final position, releasing members 42 of the lever 30 push down arms 59 of a detecting member 50 attached in a groove 13 of the female housing 10, thereby releasing stopping members 60 of the arms 59 from an engaged state against regulating members 18 which protrude from side faces of the groove 13. As a result, the detecting member 50 can be pushed in an anterior direction. This movement of the detecting member 50 allows one to detect that the two housings 10 and 20 have been correctly fitted together.

  • Patent number: 4412562
    Abstract: A selvage apparatus including a photo-cell type device for detecting abnormal conditions of selvage threads is disclosed. In the detecting device comprising a microprocessor, the number of light interruptions by the selvage threads is counted and compared with a reference number, whereby abnormal conditions are detected on the basis of whether or not the number of light interruptions is less than the reference number.

  • Patent number: 4300599
    Abstract: Loss of tension in individual warp threads is detected in the lease zone by directing a flow of air against one side of the warp threads within the lease zone to displace any relatively untensioned thread toward the opposite side of said zone and detecting such displacement photoelectrically. Preferably, the photoelectric detector is insensitive to disturbances other than thread displacement.

  • Patent number: 4177838
    Abstract: Automatic loom stopping apparatus for use with a loom for detecting warp yarn breakage or improper shedding and actuate the loom stop motion means of the loom, comprising light beam emitter and detector means positioned adjacent the warp yarn path toward the supply end from the weaving zone of the loom forming a monitor light beam transversely spanning the open shed, the detector means providing a detector defect signal when any portion of a warp yarn or broken end interrupts the monitor light beam, amplifier and comparator circuitry for producing a processed defect signal responsive to the detector defect signal, timing pulse forming circuitry including a sensor monitoring rotation of the loom drive shaft for producing timing pulses indicating a predetermined phase time in the cycle of operation of the loom applied to a gate control pulse generator to produce short duration window pulses when the shed is in predetermined open condition, and first and second gate circuits conditioned by the window pulses and
