  • Patent number: 5653824
    Abstract: Methods for preparing magnetic strips are provided in which the strips are manufactured to a thickness of less than about 0.005 inches and are made of a ferrous alloy having a carbon content of from about 0.4 to about 1.2 weight percent. The strips can be prepared by first manufacturing an alloy having a carbon content below about 0.5 weight percent to the desired thickness and then subjecting the strip to a carburizing step to raise the carbon content in the strip. The strips can also be prepared by controlling the chemistry of the initial alloy and controlling the processing of that alloy until the desired thickness and requisite magnetic properties are obtained. The strips are particularly useful in EAS systems.

  • Patent number: 5470400
    Abstract: This invention relates to a process for producing a non-pyrophoric, corrosion resistant rare earth-containing material capable of being formed into a polymer bonded permanent magnet comprising forming particles from a rare earth-containing alloy, and treating the alloy with a passivating gas comprised of nitrogen, carbon dioxide or a combination of nitrogen and carbon dioxide at a temperature below the phase transformation temperature of the alloy, and heat treating the alloy to produce material having a coercivity of at least 1,000 Oersteds. Rare earth-containing alloys suitable for use in producing magnets, such as Nd--Fe--B and Sm--Co alloys, can be used. If nitrogen is used as the passivating gas, the resultant powder particles have a nitrogen surface concentration of from about 0.4 to about 26.8 atomic percent. Moreover, if carbon dioxide is used as the passivating gas, the resultant powder particles have a carbon surface concentration of from about 0.02 to about 15 atomic percent.

  • Patent number: 5253580
    Abstract: This invention relates to an apparatus and process for conveying a printed object, such as a printed bottle. The apparatus comprises a vacuum pump for supplying a vacuum and a rotationally driven central shaft operably associated with the vacuum pump. The central shaft has a bore therethrough for carrying a vacuum. A rotary disc is mounted on the central shaft for rotation therewith for conveying the printed object sequentially from a receipt station to a discharge station. The rotary disc has a front face, a back face and an internal vacuum chamber for carrying a vacuum. The internal vacuum chamber is in communication with the central shaft's bore and the vacuum pump. Additionally, the front face has at least one vacuum port. A valve system is preferably associated with the vacuum port for controlling the delivery of the vacuum to the vacuum port so that suction created by the vacuum picks-up the object at the receipt station.

  • Patent number: 5123792
    Abstract: This invention relates to an improved blind fastener assembly and an improved joint assembly using the blind fastener assembly. The blind fastener assembly is adapted to be installed in a workpiece having a first and a second surface with an opening therebetween. The blind fastener is of the type having a core pin, expander means, expandable sleeve means, and resilient washer means, each having an initial diameter which permits it to pass through the opening in the workpiece. The improvement in the blind fastener assembly in accordance with this invention comprises the washer means having two portions including an inner portion and an integrally formed outer flange portion. The inner portion has a tapered nose section tapering outwardly away from the core pin shank portion to facilitate expansion of the sleeve means over the inner portion. The integrally formed outer flange portion is adapted to be unfolded by the sleeve means to form a bearing surface against the second surface of the workpiece.
