  • Patent number: 6560510
    Abstract: An apparatus and method for the efficient simultaneous loading and unloading a plurality of compact disc media into and out of a plurality of recording bays. The present invention provides a plurality of two position platters that allow the simultaneous rotation of a plurality of compact discs along horizontal planes defined by the platters above compact disc drive input trays for the transfer of the compact discs to a plurality of compact disc drives using a plurality of associated compact disc lifting devices that lift the compact discs off the platters allowing the platters to rotate along a central axis and then distributes the plurality of compact discs into the compact disc trays. One platter is used for each compact disc recording or writing drive.

  • Patent number: 5873692
    Abstract: An apparatus and method for picking up a single compact disc from a stack of compact discs wherein each disc has a hub. A plurality of members are inserted into a center bore of the disc stack, which is defined by the hubs of the discs. The top disc in the stack is separated from the stack when a sufficient number of members are in contact with the hub of the disc and a radial force is exerted on the hub.

  • Patent number: 5112429
    Abstract: A labeling apparatus is presented. The apparatus has a pair of stationary rollers. There is a gap between the rollers. An idler wheel is positioned opposite the stationary rollers to engage the object and hold it against the rollers. A floating pin is positioned between the rollers and the object. The pin diameter is larger than the roller gap. A continuous web of labels is threaded through the gap and around the pin. When the web is advanced, the tension forces the web and pin against the rollers causing the rollers to rotate in the opposite direction, thus driving the engaged object forward. As the web advances, the label does not follow the diameter of the pin and is separated from the web and applied to the object. An object supply hopper has separating means for providing individual objects to the rollers. The entire apparatus is angled relative to the horizontal plane. The hopper is oblique to the plane of the object.

  • Patent number: 5019929
    Abstract: A device for duplicating magnetic disks and the like includes an inlet bin for holding magnetic disks, a motorized picker for selecting a disk from the bin along a substantially straight line pathm, a pressure roller for receiving the disk as it exits the bin and positioning the disk in a processing device, and a leaf spring for redirecting the path of the disk as it exits the processing device.

  • Patent number: 4903154
    Abstract: Serially transporting diskettes from a stack to at least one disk drive for recording of a selected program thereon and then transporting the diskettes to at least one output stack. Included is input hopper for receiving diskettes onto which the selected program is to be recorded in a disk drive mounted in substantial vertical alignment with said input hopper. In addition, there is means for extracting one diskette at a time from the input hopper, and transporting the diskette from the extraction means, away from the input hopper, redirecting the last edge of the diskette to leave the hopper means vertically toward the mouth of the disk drive, insertion therein and removal therefrom, and finally transporting it to an output stack.
