Abstract: A method and apparatus for double-sided scanning of a paper document comprising diagonally offset scanner and traction pinch roller pairs thereby forming a zero-gravity traction feed. The zero-gravity traction feed allows the scanning apparatus to be oriented in varying positions while maintaining full operation. The scanner is adapted to scan a two-sided document by flip-flopping between two scanners whose field of views each face opposing sides of the document.

Abstract: A tool for applying an identification tag body and a tag retainer to an ear of an animal. The tool includes a main handle member on which a tag body is mounted, a swinging bracket pivotally mounted on the main handle member, a second handle member pivotally connected to the swinging bracket, a first sliding link member pivotally connected to the second handle member, and a second sliding link member pivotally connected to the second handle member. The tag retainer is mounted on the swinging bracket. As the swinging bracket swings, the tag retainer can pass through the animal's ear and enter a boss of the tag body for locking therein. Support structure on each of the sliding link members can engage support pins mounted on the main handle member so that linkage of the tool can advance in two stages as the handles are advanced toward each other. The support structure of the sliding link members can come free of the associated support pins, one at a time.

Abstract: For use in photographic package printing, selected negatives are cut from the film rolls and mounted in individual paper negative carriers, imprinted with bar-coded order details. A novel reader-feeder reads the bar-coded order on each of the carrier and stores the order in the memory of its microprocessor. When photoprinting of a prior order has been completed, the reader-feeder withdraws the prior negative carrier, feeds the newly-read negative carrier to the package printer, and inputs its stored order to a conventional printer-controller, which directs the photoprinter in the same manner as if an operator was key-inputting the order into the printer-controller.The paper negative carriers are supplied in manifold form, for computerized imprinting. These consist of die-cut front sheets having an adhesive backing on a waxed manifold web. Aligned rectangular cut-outs, the larger of which is in the web, provide an adherent mounting frame when the cut-out portions are removed.
