  • Patent number: 4818055
    Abstract: A splice connector for making butt splices in optical fibers include an element formed of a deformable material and formed to define three surfaces for contacting the fibers to be spliced. The surfaces are formed between two levers of the element such that when the levers are moved toward each other the surfaces defining a fiber receiving passageway are closed onto a pair of fiber ends and the surfaces center the fiber ends and the levers afford a resilient spring compression reserve force on the aligned fiber ends to maintain them in contact. The element is placed in a plastic base and a cover, that fits onto the base, is placed over the element to close the levers of the element when the cover is closed.

  • Patent number: 4796781
    Abstract: A desk type dispenser for dispensing note sheets which are adhered together along opposite alternate edges by a narrow band of adhesive coated on one surface of the sheets comprises a base member and a body member. The body is preferably weighted and sits on the uppermost sheets in the stack and is provided with a dispensing opening therein which communicates with arcuate wall members communicating with the bottom surface thereof. Recesses in one of the body and base and projections in the other member cooperate to afford a nesting of the base and the body. A platform on one of the members and a recess on the other affords a positioning of the stack of sheets with respect to the two members and stability for the stack of sheets.

  • Patent number: 4781306
    Abstract: A stack of flexible sheet material for use in a dispensing device for dispensing individual sheets. The sheets are stacked with alternately opposite edges of successive sheets coated along one edge with a narrow band of readily releasable repositionable pressure-sensitive adhesive. The dispenser comprises a container having a pair of sidewalls connected by a top wall which is formed with a transversely extending rectangular opening extending in the direction parallel to the sidewalls. The stack of sheets are placed within the dispenser such that upon removing the uppermost sheet in the stack the adhesive coating along one edge of the sheet parallel to the opening and adhered to the free edge of the next sheet in the stack will cause the next sheet in the stack to be withdrawn at that free edge through the dispensing opening upon withdrawal of the adhesive coated edge of the uppermost sheet.

  • Patent number: 4781782
    Abstract: A taping head for applying a film of pressure sensitive adhesive to a receptor surface has a drive means for driving the adhesive to the applicating roller by driving a liner supporting the adhesive, and a dancing roll positioned between the apparatus for stripping the liner from the adhesive and the applicating roller adjusts the speed of movement of the film of adhesive to match the same with the application of the adhesive. The applicator is pressed against the receptor surface under the control of a compression device and a cutting device for adhesive severs the adhesive below the applicating roller and an air nozzle maintains the cut end of the adhesive in a position for subsequent application.

  • Patent number: 4768810
    Abstract: A writing tablet is formed from a substantially continuous, fanfolded web of uniform width having transverse paths of weakness, along which the web can be torn evenly into individual sheets of uniform size. One face of the web bears a series of pressure-sensitive adhesive patterns, one pattern on each sheet, which pattern contacts the adhesive-bearing face of an adjacent sheet only in nonadhesive areas. The pressure-sensitive adhesive and nonadhesive areas are so prepared that each sheet can be cleanly peeled from the adjacent sheet without adhesive transfer, even after prolonged storage. After the tablet has been formed, its sheets can be conveniently and efficiently imprinted in a printer or copier and then returned to tablet form.
