  • Patent number: 8132347
    Abstract: When displaying products on a display hook, labels associated with the products are oftentimes presented via a label holder affixed to the display hook. Because various display hook structures exist, an interchangeable label holder can be utilized to adjoin to the various structures. Accordingly, in one embodiment, a label holder is adapted for being affixed to both a cylindrical-shaped crossbar and a display plate crossbar of a display hook. The rear face of the interchangeable label holder includes first brackets and second brackets adapted for receiving either the cylindrical-shaped crossbar or the display plate crossbar. The rear face of the interchangeable label holder also includes a first securing element and a second securing element functional for receiving lateral edges of the display plate crossbar to restrict lateral movement of the label holder.

  • Patent number: 7831633
    Abstract: Methods and apparatus for supporting an additional data source in a system adapted for processing data from one or more data sources are disclosed. A design-time driver for the additional data source is obtained, where the design-time driver supports the definition of data including one or more fields of the additional data source to retrieve from the additional data source. In addition, a run-time driver for the additional data source is obtained, where the run-time driver supports retrieval of data corresponding to the one or more fields from the additional data source and where the run-time driver has a second application programming interface. The design-time driver is executed via a first application programming interface, where the first application programming interface enables definition of the data including the one or more fields to be retrieved from the additional data source.

  • Patent number: 7667355
    Abstract: A linear motor comprising a coil assembly and a magnet assembly is provided with a cooling apparatus which comprises a segmented air knife assembly. The segmented air knife assembly has a plurality of slot openings distributed along its length which is coupled to the linear motor and it is operative to discharge cooling air into a gap between the coil assembly and magnet assembly in a discharge direction. An inclined surface extends from the plurality of slot openings and slopes at an obtuse angle away from the discharge direction of the cooling air. Each slot opening is individually configured to discharge the cooling air in the discharge direction at a sufficient velocity so as to entrain atmospheric air along the inclined surface to amplify the cooling air that is so discharged.

  • Patent number: 7514825
    Abstract: A cooling apparatus is provided for a linear motor that comprises a coil assembly and a magnet assembly, wherein the coil assembly generates heat during operation. The cooling apparatus comprises a compressed air inlet positioned to discharge compressed air in a direction directly towards a gap between the coil assembly and magnet assembly, and an inclined surface extending from the compressed air inlet and sloping at an obtuse angle away from the discharge direction of the compressed air. The compressed air inlet is configured to discharge the compressed air at a sufficient velocity so as to entrain atmospheric air along the inclined surface to amplify the compressed air that is discharged.

  • Publication number: 20090056761
    Abstract: A bonding apparatus for bonding materials onto a substrate supported on a substrate support is provided with an air generator that is arranged and configured to direct an air flow onto the substrate during bonding. The air generator is located on one side of the substrate support, whereas a suction device is located on an opposite side of the substrate support which is operative to draw the air flow away from the bonding apparatus. The air generator further comprises an air knife that is operative to generate a unidirectional air flow over an entire length of the substrate during bonding.
