  • Patent number: 11382440
    Abstract: A cuboctahedron-shaped photo cube, comprised of six identically folded sheets of strong, but flexible transparent thermoplastic, assembled to allow the display of six two or three dimensional pieces of art or other objects. Each sheet has a square area, serving as a display panel and is accompanied by a backing sheet to press two-dimensional art firmly against it. Users access the interior by pulling a sheet from the structure. Art or objects are then placed inside the unit. To replace the removed sheet, one of its winged tabs is pinched with a thumb and forefinger and inserted into one of the available slots on the structure until it snaps into place. This action is repeated for the remaining aligned tabs and slots. The purpose of this invention is to present six display panels simultaneously without any being placed on the bottom, hidden from the viewer.

  • Patent number: 3961703
    Abstract: A conveyor system for use in processing lengths of flexible material in which the conveyor system is formed of a pair of parallel spaced chains adapted to be displaced longitudinally and carrying a plurality of gripping devices positioned to successively receive lengths of flexible material from a source thereof. The lengths of flexible material are conveyed in an intermittent fashion to permit various work operations to be performed on the successive lengths of flexible material. The gripping devices include a body member fixed to the conveyor having a notch therein adapted to receive a cross section of the lengths of flexible material, and a lever pivotally mounted on the body member and having a arcuate surface adapted to secure the lengths of flexible material in the notch of the body member.
