Abstract: A system that controls a back reaming operation of a drilling rig is provided that includes a hoisting system that moves a drill pipe during a back reaming operation at a hoisting speed and a hoisting torque. The hoisting system comprises at least one back reaming parameter sensor for measuring a corresponding at least one back reaming parameter. An operator control unit allows an operator to input a predetermined value of the at least one back reaming parameter therein. A back reaming parameter sensor obtains the measured value of the at least one back reaming parameter. A control system monitors the at least one back reaming parameter. A braking assembly resists the hoisting torque of the drawworks system when the measured value of the at least one back reaming parameter equals the predetermined value of the at least one back reaming parameter.

Abstract: A blower for use to provide combustion air to a fire (e.g., to assist in the lighting of a fire). The blower may include a cylindrical housing having an inlet opening and an outlet opening with a bore extending between the inlet and the outlet. A fan and power source may be provided to induce air flow from the inlet opening and through the bore such that air is expelled from the outlet opening. The outlet air exiting the outlet opening may travel in a direction substantially parallel with a central axis of the cylindrical housing. The blower may be supported by an infinitely adjustable flexible member that may be manipulated to position the blower with respect to the fire to provide outlet air to the fire. The flexible member may be engaged with a clip to attach the blower to a structure adjacent to the fire.
