  • Patent number: 6378086
    Abstract: A method for recovering a computer system from a loadsource direct access storage device located at a remote location. In accordance with the method and system of the present invention, after a catastrophic damage and the installation of a local loadsource direct access storage device, an indicator within the local loadsource direct access storage device is set such that the local loadsource direct access storage device cannot be utilized for initial program load. Thereafter, the contents of the entire loadsource direct access storage device located at a remote location are copied to the replacement local loadsource direct access storage device. The indicator within the replacement local loadsource direct access storage device is reset such that the replacement local loadsource direct access storage device can be utilized for initial program load again. Finally, an initial program load is performed from the replacement local loadsource direct access storage device.

  • Patent number: 5806235
    Abstract: An apparatus for containing, threading and dispensing fish hooks, wherein said fish hooks comprise a hook portion and an eye portion. The apparatus comprises an enlongated housing having a length, an axis coextensive with said length, a bore extending along said axis the length of said housing, an open front end lying in a plane substantially perpendicular to the axis, and a back end. A grooved shaft, having a front end and a back end, is rotatably mounted within the bore and extends along said axis. A spiral groove is cut around the perimeter of the grooved shaft, wherein the groove is adapted to contain the hook portions of a plurality of fish hooks. An eye groove extends out from the bore into the housing and extends along the length of the bore in the direction of the axis. The groove is adapted to contain the eye portions of the plurality of fish hooks.

  • Patent number: 5632027
    Abstract: A method for updating mass storage device configuration records during a configuration change within a computer system is disclosed. A unit configuration record is stored in a system mass storage device. The unit configuration record is unique to each system and it includes a configuration identification, a sequence number and an alteration count table. In addition, a logical device identifier is stored in each mass storage unit within the system. The logical device identifier is unique to each mass storage device unit and it includes a configuration identification, a unit number and an alteration count. If a configuration update is necessary, the corresponding alteration count of the unit configuration record is first incremented, a new logical device identifier is then built with the new alteration count, and finally the new logical device identifier is written to a mass storage device that requires update.

  • Patent number: 5185884
    Abstract: A method of pairing disk units in a computer system where mirroring is desirable is disclosed. Where possible, disk units are paired with other disk units located on a different bus. This provides the highest level of protection against inaccessible data due to data loss or failure of a component in the computer system. Where this is not possible, the remaining disk units are paired with disk units located on a different I/O processor, a different controller, or a different disk enclosure. Where none of these pairings are possible, the remaining disk units fall below the threshold level of protection and therefore cannot be paired within the segment. Any disk units that could not be paired are placed on a spare list. Several attempts are made to pair up disk units on the spare list. If all of these attempts fail, the paired disk units with the lowest level of protection are broken apart and added to the spare list, where attempts are again made to pair up the disk units on the spare list.

  • Patent number: 4690303
    Abstract: A coupon packet housing defines a vertically disposed compartment for receiving a stack of substantially vertically aligned, vertically juxtaposed packets. A forwardly and rearwardly movable reciprocable floor plate underlies the compartment and has a flat surfaced, recessed portion extending rearwardly from its front end to define a generally vertically disposed dispensing shoulder which lies adjacent the rear of the compartment when the plate is in rearward position. The lowermost packet is received in the recessed portion, and is separated from the stack and then the recessed portion when the plate is respectively moved forwardly and thence returned rearwardly.

  • Patent number: 4566581
    Abstract: A coin operated vending machine is provided for delivering the uppermost of a stack of generally horizontally disposed article such as newspapers, out a delivery opening or vending slot. The machine employs an upright pedestal with a top wall for supporting a stack of the articles to be dispensed, and an enclosing cabinet shell is telescopingly received over the upper end of the pedestal and has an article engaging dispensing slot. The pedestal supports the cabinet shell in telescopic position which changes incrementally each time a newspaper is vended. The article is rotated through an arc in the dispensing of the newspaper and a latch bar associated with the dispensing mechanism is movable to latched or unlatched position, dependent on whether or not proper coins have been inserted.

  • Patent number: 4428503
    Abstract: A machine for vending newspapers and the like singly wherein a closed cabinet has an oblong dispensing opening in an upper portion of a side wall thereof. A newspaper supporting tray is mounted for vertical travel in the cabinet via the action of a spring and cable system which raises the newspaper stack progressively to dispose the topmost newspaper opposite the dispensing opening. A verticlly movable pushing finger assembly is mounted for vertical travel on a dispensing pusher frame which also includes a top stop for limiting upward travel of the stack.

  • Patent number: 4232800
    Abstract: Apparatus for individually dispensing cylindrical articles, such as rolled newspapers and the like, comprising vertically inclined, juxtaposed racks for storing articles which travel therealong by the force of gravity, and an adjustable width chute adjacent the terminal ends of the racks and spaced therefrom to receive articles from the rack and downwardly pass them in a vertical stack, a gate movable between a blocking position in the path of the lowermost article in the column and a non-blocking position permitting the lowermost article to downwardly pass, and stack support mechanism movable between a remote position when the gate is in the blocking position and an operative position in the path of the second lowermost article when the gate is in the non-blocking position to interrupt the downward passage and vertically support the balance of the articles which trail the lowermost article.
