20160129760 | AIR CONDITIONING SYSTEM FOR MACHINE - An air conditioning system for a machine is disclosed herein. The machine has an engine, a radiator operably connected to the engine, and a radiator fan to generate a flow of air over the radiator. The air conditioning system includes a condenser, at least one condenser fan, a sensor, and a control unit. The condenser condenses a refrigerant and is structured and arranged to directly receive at least a portion of the flow of air generated by the radiator fan. The at least one condenser fan selectively generates a flow of air over the condenser. The sensor measures at least one of: an engine speed, a temperature of the condenser, and an airflow through the condenser. The control unit selectively controls the at least one condenser fan based on the at least one of: the engine speed, the temperature of the condenser, and the airflow through the condenser. | 05-12-2016 |
20150343908 | MULTI-PHASE POWER SYSTEM - Mining vehicles and power systems for use with such vehicles are provided. One power system includes a synchronous generator circuit configured to generate an alternating current (AC) power signal distributed across at least six phases. The power system further includes a rectifier circuit including at least twelve diode devices and configured to receive the AC power signal distributed across the at least six phases from the synchronous generator circuit and generate a direct current (DC) power output signal. The DC power output signal includes at least twelve pulses for a single wave of the AC power signal received from the synchronous generator circuit. The rectifier circuit is configured to output the DC power output signal for use in powering a load device of the mining vehicle. | 12-03-2015 |
20150285405 | AFTERCOOLER PIPE SUPPORT ASSEMBLY - A support assembly for a pipe arrangement includes a bracket, a clamp configured to couple to the pipe arrangement, and linkage assemblies coupled to the bracket and the clamp. The linkage assemblies include a rod, a first connector coupled to the rod at a first end and coupled to the bracket by a first locking assembly at a second end, and a second connector coupled to the rod at a first end and coupled to the clamp by a second locking assembly at a second end. The first connector is configured to rotate relative to the bracket about the first locking assembly and the second connector is configured to rotate relative to the clamp about the second locking assembly to allow movement of the clamp relative to the bracket in a first plane. A tightening assembly is adjustable to move the clamp relative to the bracket in a second plane. | 10-08-2015 |
20140343754 | REMOTE CONTROL SYSTEM FOR DRILL - Mobile drilling devices and systems, methods, and computer-readable media for controlling such devices are provided. One method includes receiving user input from a user of a mobile computing device. The method further includes transmitting data based on the user input from the mobile computing device to a control circuit of a mobile drilling device via a wireless network connection. The method further includes generating a plurality of control signals based on the data received from the mobile computing device. Each of the plurality of control signals is configured to control movement of a separate one of a plurality of movement devices of the mobile drilling device. The plurality of movement devices are configured to move the mobile drilling device between locations. | 11-20-2014 |

20140262395 | DRILLING APPARATUS - A drilling apparatus includes a percussive member configured to generate impact waves, a striking bar configured to receive impact waves from the percussive member, a rotation section at least partly enclosing the striking bar, a flushing section detachably connected to the rotation section, and a vibration isolator attached to the flushing section. The rotation section includes a bearing configured to support the striking bar. Further, the flushing section includes an inlet passage configured to receive a flushing medium. | 09-18-2014 |
20140083774 | DRILLING TOOL CHANGER APPARATUS - A drilling tool changer apparatus for a drilling rig includes a drill tower pivotable between a drilling orientation and a change-out orientation, the drill tower supporting a drill string comprising a drill pipe coupled to a drilling tool. The drilling tool changer apparatus also includes a drilling tool storage device pivotally movable about a hinge axis between a stowed position and a deployed position. The drilling tool storage device includes a drilling tool storage cassette including a replacement drilling tool. The drilling tool storage device and the drill tower are pivotally alignable in a substantially co-planar manner when the drilling tool storage device is in the deployed position and the drill tower is in the change-out orientation. | 03-27-2014 |
20140083765 | AUTOMATIC CONTROL SYSTEM AND METHOD FOR A DRILLING TOOL CHANGER APPARATUS - A control system for an automatic drilling tool changer apparatus for use with a drilling rig includes a drilling control device programmed with a control scheme for controlling the automatic drilling tool changer apparatus, and a user interface coupled to the drilling control device for initiating actions of the automatic drilling tool changer apparatus and for interactively monitoring a status of the automatic drilling tool changer apparatus. The control scheme includes steps for an automatic drilling tool change-out operation, and the drilling control device and the user interface are configured to communicate with the automatic drilling tool changer apparatus over a network. | 03-27-2014 |
