  • Patent number: 4482900
    Abstract: An antenna apparatus for use in space which is foldable into a small package for storage in a space vehicle. The antenna apparatus utilizes a plurality of hinged members and diagonal tapes forming parallelogram frames, two opposite sides of which are hinged at the center to fold the frames in a given plane. Similar frames are hinged on the first frames in a second plane whereby a plurality of cubes are formed when all are unfolded.

  • Patent number: 4127078
    Abstract: A yarn adjuster positioned adjacent tufting needles in a tufting machine for engaging yarn in close proximity to the tufting needles and moving it a predetermined distance to thereby control the length of the yarn on each side of the needles which controls evenness of tufts particularly when dual tufting needles are utilized to tuft U-shaped tufts. The yarn adjuster may be driven by an improved coupler point drive featuring long dwell and fast rise.

  • Patent number: 4119047
    Abstract: A cutter mechanism for use in a tufting machine or the like featuring a stationary blade having openings through which yarn strands project, the stationary blade being positioned in the path of travel of yarn strands from yarn creels to bit-applying elements with the cutter mechanism further featuring a series of reciprocable blades which are biased against the stationary blade whereupon reciprocation the reciprocable blades will pass over the openings and because of their biasing effect, penetrate the plane of the stationary blade passing into the openings thereby severing the yarn strands.

  • Patent number: 3937160
    Abstract: A yarn control and feeding apparatus for use with tufting machines and similar apparatus wherein yarn, normally precut, is tufted into a backing layer. A pulsing-type solenoid actuator is utilized to selectively control yarn metering and feeding functions carried out by a rotatable yarn feed wheel and to further control pneumatic yarn transport means including advancing and retracting yarn during various stages of the tufting cycle.
