Abstract: Method and apparatus for making hollow links or rings and for making chain made from hollow links by receiving seamless wire which has an inner core and an exterior surface, for example, a gold alloy surface, making a perforation in the wire so as to expose the inner core at the perforation, and forming the wire into an open or closed link such that the perforation is located on a hidden portion of the link. The inner core may then be removed from the open or closed link by dissolving it in acid, wherein the acid contacts the inner core at the perforation thus allowing the acid to dissolve the inner core. A chain may be made by coupling each link with at least one preceding link to produce the chain.

Abstract: In a machine for loading tape into cassettes, the cassettes to be processed are oriented horizontally and disposed one upon the other to form a stack vertically engaged in a magazine. A collapsible support located at the base of the magazine engages the lowermost cassette in the stack in order to orient it vertically and let it fall into fitting guide pieces associated with a loading station located in the loading machine. A retention element operable by an actuator maintains the positioning of the cassette on the collapsible support while the latter is moving to the dropped position.

Abstract: Devices for the duplication of industrial magnetic tapes. More particularly it relates to an electronic device for the fast duplication of magnetic tapes. The device, through a microprocessor, activates selecting circuits to control static memory cards of a memory bank. The selecting circuit generates proceeding signals and selecting signals which single out memory cells of the memory bank for writing and reading. These selecting signals and proceeding signals cause a subdivision of the cards in the memory bank, allotting a part of the memory for reading and another part for writing. The selecting and the proceeding signals are carried out through digital signals. The final digital signals are subjected to a digital-to-analog conversion.

Abstract: A system and method for tracking compact discs during manufacture comprising a spindle having a central shaft and a base for carrying a plurality of compact discs, electronic memory storage system connected to the spindle, and data transfer means cooperating with the spindle to send and receive information identifying compact discs carried by the spindle and/or providing processing information about compact discs carried by the spindle from or to the electronic memory storage system.

Abstract: An apparatus for packaging compact disc into respective cases along feed line having one station for opening the cases, a first work station in which an informational leaflet and informational booklet are respectively inserted in a housing portion and a lid portion of the case, a second work station in which a compact disc is engaged with a tray, if present, and a cover are respectively inserted in the housing portion and lid portion, and a final station for closing the case. The lid portion of the case is rotated by means of air blowing nozzles positioned at the opening and closing stations, respectively, to direct an air flow against the lid portion.
