  • Publication number: 20060042315
    Abstract: A glass handling system and method are described herein where an enhanced robot is used to engage and hold a glass sheet in a manner that minimizes the motion of the glass sheet as it is moved from one point to another point in a glass manufacturing facility. The enhanced robot engages and holds the glass sheet by using one or more suction cups and one or more aero-mechanical devices. The suction cups contact and support the outer edges or non-quality area of the glass sheet while the glass sheet is moved. And, the aero-mechanical device(s) emit gas towards the center portion or quality area of the glass sheet in a manner which enables the aero-mechanical device to support and hold the quality area of the glass sheet without contacting the glass sheet while the glass sheet is moved.

  • Patent number: 5203751
    Abstract: An exercise device including a pair of tracks, a bracket slidably disposed on each of the tracks, a pair of rails disposed above the tracks, a slide slidably disposed on each of the rails, a handle coupled to each of the slides, and a cable threaded along the tracks and along the rails and formed into a closed loop. The brackets and the slides are coupled together by the cable so that the brackets and the slides move in concert.

  • Patent number: 4962925
    Abstract: An exercise bicycle includes a frame body having a seat and a pair of handles. A vane wheel is rotatably supported on a rear end of the frame body. A multi-axial crank is pivotally supported on the frame body. A lower end of each handle is coupled to one of two crank axles of the multi-axial crank. A rotation of the multi-axial crank makes a back and forth movement of the lower ends of the handles, and the back and forth movement of the lower ends of the handles makes a rotation of the multi-axial crank.
