Patent number: 4969105Abstract: When tensioning a gasketed joint, the drive system applies rotational force to a threaded fastener while the monitor and control unit continuously compares a torque-related variable to a shutoff point. When the shutoff point is reached the control system reduces the drive system power, preferably to zero. After a preselected time pause the drive system is re-energized and applies another torque application until the torque-related variable again reaches the shutoff point. When the gasket is adequately compressed so that further torque applications cause insignificant increases in gasket compression, the tensioning operation is terminated. Feedback is provided by tension-related variables such as incremental angle of turn and/or incremental elapsed time of the torque application to determine when the tensioning cycle is complete.Type: GrantFiled: May 2, 1988Date of Patent: November 6, 1990Assignee: Ingersoll-Rand CompanyInventor: Heinz Gaenssle

Patent number: 4927323Abstract: A radical flow mechanism is provided having a symmetric housing assembly defining a hollow rotor chamber. A symmetric shaft and rotor assembly is supported for rotation in the rotor chamber. A plurality of radial flow paths are defined by the rotor and the housing assembly. The assembled module may be powered by a pressurized motive fluid that flows radially inward to rotate the rotor. Alternatively, the rotor may be driven by an external power source so that a working fluid increases in potential energy as it moves centrifugally outward. The assembled module is symmetric about the rotor member so that the rotor can be orientated for either direction of rotation and so that power takeoff or power connection can be to either side of the module. Also, the module is constructed so that the seals are located at an interface having a low pressure differential and the bearings are located adjacent an area encouraging heat dissipation.Type: GrantFiled: December 28, 1988Date of Patent: May 22, 1990Assignee: Ingersoll-Rand CompanyInventor: Robert R.

Patent number: 4919022Abstract: The powered ratchet wrench 10 is constructed of several components. A throttle lever 20 controls the air flow to a rotary air motor 30. The rotary output of the motor is transmitted to the hammer assembly 40 of an impact clutch mechanism. A spring 50 biases an anvil shaft 60 into association with the hammer assembly 40. The anvil can be directly driven by the motor through the hammer assembly or can be driven intermittently by a series of rotational impacts from the hammer assembly. The rotation of the anvil shaft causes the reversible ratchet mechanism 70 to rotate in the desired direction, thus tightening or removing a threaded fastener. Only a small reaction force is transmitted by the tool to the operator once the fastener is tightened.Type: GrantFiled: June 5, 1989Date of Patent: April 24, 1990Assignee: Ingersoll-Rand CompanyInventors: Akira Ono, Toshiro Iritani

Patent number: 4917569Abstract: A containment system for a radial flow turbine assembly includes a housing assembly, and a turbine rotor journalled for rotation about an axis and having a hub portion and a generally tapering disc portion extending radially outward from the hub portion. An annular nozzle assembly normally secured in the housing assembly against rotation forms a tapered rotor chamber within which the rotor rotates with minimum axial and radial clearance between the rotor and the chamber. A plurality of support struts extend axially inward from the nozzle assembly to a minimal axial and radial clearance with the hub portion of the rotor and forms a first stage of containment. The rotor must first break through the nozzle struts and separate the nozzle assembly. A rotatable nozzle assembly then absorbs some of the force by rotating in the housing assembly and containment ring. An armored containment ring stops the fragments that escape the nozzle assembly and finally, an outer housing provides still further containment.Type: GrantFiled: November 3, 1988Date of Patent: April 17, 1990Assignee: Ingersoll-Rand CompanyInventor: Robert R.
