Abstract: A storage rack suitable for maintaining sheet material free of surface scratches, dents, dings, etc. caused by handling and moving. A rectangular frame as large as the largest sheet to be stored is suspended from an overhead monorail. A channel member forming the lower edge of the frame supports the sheets which lean against the frame and are held in place by diagonal straps. A plurality of parallel overhead rails each of which supports a single frame provide the storage area. The overhead rails are at least twice the overall length of the frames to allow a selected frame to be moved from its storage position into the open where a desired sheet may be removed or added and the frame pushed back to its stored position without chance of damage to the sheet.

Abstract: Method and apparatus for producing a three dimensional television image by presenting stereoptican pairs of images to the viewers eyes. One of the stereoptican partners is presented most of the time while the second stereoptican partner is flashed on and off rapidly. Under the proper conditions with the second stereoptican partner being flashed on for a suitably short period of time at the proper repetition rate, the viewer is not consciously aware of its presence and effectively perceives the picture as a three dimensional image.
