  • Patent number: 8327927
    Abstract: An apparatus for performing earth borehole operations comprising a base or substructure, a mast mounted on the base, a top drive mounted on the mast for longitudinal movement therealong, the top drive having an opening therethrough and a coiled tubing injector mounted on the mast above the top drive such that coiled tubing from the tubing injector can pass through the opening in the top drive, the apparatus being operable to selectively use the top drive to engage and manipulate a component used in borehole operations while the coiled tubing injector is substantially inoperative and selectively operable to use the coiled tubing injector to inject coiled tubing into an earth borehole while the top drive is substantially inoperative or alternatively using the coiled tubing injector to inject coiled tubing into a tubular string being manipulated by the top drive.

  • Patent number: 8302677
    Abstract: A control circuit for a coiled tubing injector includes a circuit controller (14). One or more counterbalance valves (3) may be responsive to the circuit controller to prevent the tubing string from descending into the wellbore during rate of penetration movement. In one embodiment, a control valve (4) allows fluid to flow through a bypass line around the counterbalance valves when drilling in a weight-on-bit mode. Other hydraulic control circuits allow for the release of fluid pressure to control the injector hydraulic motor. In yet another embodiment, the control circuit regulates power to an electric motor of the injector.

  • Patent number: 8274363
    Abstract: A system and/or method to control access to medication and/or medical supplies may be implemented by providing secured compartments for the medication spread through a medical facility, such as in or adjacent patient rooms and/or connecting locking mechanisms to the secured compartments. Computers positioned throughout the facility are interfaced to respective locking mechanisms to operate the locking mechanism in response to access codes, which may be transmitted over the network. Additional steps may involve programming an authorization computer for providing access codes in whole or part for use with the computers. One or more access points may be functionally coupled to a computer system and/or to the locking mechanism and accessible to users for entry of requests for access to the secured compartment.
