Patent number: 8863621Abstract: A power tong includes a rotor, driven by a primary drive, for spinning and torquing threaded connections of a tubular gripped in the rotor. A grip in the rotor grips the tubular. A serpentine member supplies power to actuate the grip. The serpentine member is driven by a secondary drive. The primary and secondary drives are mounted on a stator frame. The rotor is rotatably mounted to the stator frame and driven by the primary drive during continuous three hundred and sixty degrees of rotation. A fixed or backup jaw may also be mounted to the stator frame. Tubular grippers on the fixed jaw grip a first side of a tubular joint. The grip on the rotor grips the opposite side of the tubular joint. High torque low-rotational speed applied to the rotor torques the joint. Low torque high-rotational speed applied to the rotor spins the joint.Type: GrantFiled: February 6, 2012Date of Patent: October 21, 2014Inventor: Allan Stewart Richardson

Publication number: 20120272792Abstract: A power tong continuously rotates tubulars for spinning and torquing threaded connections. Continuous rotation is achieved through a rotating jaw having a grip that grips the tubular and continuously rotates with it. A serpentine supplies directly or indirectly power to actuate the grip. The serpentine is driven by a secondary drive mounted on a fixed frame. The rotating jaw is rotatably mounted to the fixed frame and driven during continuous three hundred and sixty degrees of rotation by a primary drive, mounted on the fixed frame. A fixed jaw may also be mounted to the frame. Tubular grippers on the fixed jaw grip a first side of a tubular joint. The grip on the rotating jaw grips the opposite second side of the tubular joint. High torque low-rotational speed applied to the rotating jaw torques the joint.

Patent number: 8109179Abstract: A power tong continuously rotates tubulars for spinning and torquing threaded connections. Continuous rotation is achieved through a rotating jaw having grippers that grip the tubular and continuously rotate with it. Hydraulic and electrical power necessary for actuating the grippers is generated on board. A serpentine belt system turns the motors of the on-board hydraulic power unit and electric generators to supply the grippers with hydraulic and electrical power. The serpentine belt system is driven by a secondary drive mounted on a fixed frame. The rotating jaw is rotatably mounted to the fixed frame and driven during continuous three hundred and sixty degrees of rotation by a primary drive, mounted on the fixed frame. A fixed jaw is also mounted to the frame. Tubular grippers on the fixed jaw grip a first side of a tubular joint. The grippers on the rotating jaw grip the opposite second side of the tubular joint. High torque low-rotational speed applied to the rotating jaw torques the joint.Type: GrantFiled: February 12, 2009Date of Patent: February 7, 2012Inventor: Allan Stewart Richardson

Publication number: 20110271914Abstract: Flue-gas analysis safety apparatus 10 for a gas or oil-fired device 30 having an electrical connection and a flue 54 for combustion gases, comprises a hazardous gas detection element 12 for placement in the flue 54 to monitor flue gas, and a controller 14 for automatically regulating a gas to air ratio in the flue gas based on a signal from the hazardous gas detection element 12. The controller 14 is able to halt a flow of electricity to the gas or oil-fired device 30 if the gas to air ratio in the flue gas cannot be regulated to fall within a predetermined safe parameter. Preferably, the hazardous gas detection element 12 includes a wireless transmitter, and the controller 14 includes a wireless receiver so that the hazardous gas detection element 12 is wirelessly communicable with the controller 14. A gas or oil-fired device having the apparatus 10, and a method are also provided.Type: ApplicationFiled: July 22, 2009Publication date: November 10, 2011Inventors: Callum Scott Stewart Richardson, Richard James Crawfprd
