Patents by Inventor David Rother

David Rother has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6983795
    Abstract: A gravel packing system featuring pressure actuated sliding sleeve valves mounted to an exterior annulus around a blanking pipe for screen sections is disclosed. An internal sliding sleeve valve is provided for subsequent closure of access through the screens. The presence of the annulus between the blanking pipe and the screen permits a backup access through perforating the blanking pipe while not damaging the screen. The sliding sleeve valves that are mounted internally and externally on the blanking pipe are removable apart from the screen section that already has gravel packed around it, if they fail to operate and need repair.
    Type: Grant

  • Patent number: 5914918
    Abstract: An apparatus for recording and verifying information recorded on compact disks and for printing label information on the disks, and a method of operating the apparatus, wherein the respective recorders, verifiers, and printers are vertically stacked in a housing, and a vertically movable carriage is arranged to transport compact disks to each of the stacked devices. A rotatable carousel is mounted to the housing beneath the carriage; the carousel having multiple bins for receiving and holding compact disks. A computer processor controls the actuation of the respective devices, the carriage, and the carousel, to sequentially process unrecorded compact disks through the steps of recording, verifying and printing, and to reject compact disks which have failed the verification tests. A camera may be connected to the housing and uses in conjunction with the computer processor to rotatably position a compact disk into a preferred position prior to the printing step.

  • Patent number: 5435390
    Abstract: An apparatus and method of dropping a pumpdown plug or ball is revealed. The assembly can be integrally formed with a plug-dropping head or can be an auxiliary feature that is mounted to a plug-dropping head. The release mechanism is actuated by remote control, employing intrinsically safe circuitry. The circuitry, along with its self-contained power source, actuates a primary control member responsive to an input signal so as to allow component shifting for release of the pumpdown plug or ball. Multiple plug-dropping heads can be stacked, each responsive to a discrete release signal. Actuation to drop the pumpdown ball or plug is accomplished even while the components are rotating or are moving longitudinally. Using the apparatus and method of the present invention, personnel do not need to climb up in the derrick to actuate manual valves.
