| 20110278068 | REGENERATIVE DRIVE MECHANISM FOR HYDRAULIC FEED CYLINDERS IN HYDROSTATIC OR HYDRAULIC CIRCUITS - Methods and systems for storing kinetic energy in a fluid-base power circuit. A regenerative control valve manifold diverts fluid flow from a hydraulic device performing a first operation into an accumulator. The accumulator stores a fluid volume sufficient to perform a second operation. The regenerative control valve manifold connects the accumulator to the power circuit providing a fluid flow and charge pressure sufficient to perform the second operation. | 11-17-2011 |
| 20110266064 | FEED CABLE SYSTEM FOR A TOWER OF A DRILLING MACHINE - A drilling machine includes a feed cable system which operatively couples a rotary head to a tower. The feed cable system includes first and second pull up cables and an equalizer bar, wherein the equalizer bar is coupled to the first and second pull up cables. The equalizer bar drives the rotary head to be held in a level position so that it is restricted from tilting. The drilling machine includes a slack take up device which couples the equalizer bar to the tower. The slack take up device is repeatably moveable between extended and retracted conditions. | 11-03-2011 |
| 20110162296 | PIVOTABLE TOWER FOR ANGLED DRILLING - An interface apparatus between a tower and platform includes a tower support assembly with opposed angle brackets and a first tower support assembly coupler/decoupler which is repeatably moveable between coupled and decoupled conditions with the tower support assembly. In the coupled condition, the coupler/decoupler is capable of coupling to the tower support assembly at a plurality of predetermined positions along the opposed angle brackets. The interface apparatus includes a second tower support assembly coupler/decoupler which allows the tower to pivot relative to the tower support assembly and rotate relative to the platform. | 07-07-2011 |
| 20110083903 | DRILLING MACHINE POWER PACK WHICH INCLUDES A CLUTCH - A drilling machine includes a compressor coupled to a prime mover through a hydraulic clutch, wherein the hydraulic clutch is repeatably moveable between engaged and disengaged conditions. The compressor is allowed to provide air and is restricted from providing air in response to the hydraulic clutch being in the engaged and disengaged conditions, respectively. The hydraulic clutch is moveable between the engaged and disengaged conditions during operation of the prime mover. | 04-14-2011 |
