    Abstract: A hydrodynamic bearing in the form of a flex pad bearing includes configurations structured to change a bearing characteristic. One form of the bearing includes a nonlinear back wall that includes a circular arc and a transition, where the back wall extends radially outward of a ligament. The bearing can include an opening for the deposit of a weighted mass, wherein the opening can threadingly receive a threaded weighted mass. In one form a sidewall that includes the back wall segment can have an average outer radius which determines a thickness of the flex pads.

    Abstract: Illustrative embodiments of ratchet tools are disclosed. In one embodiment, a ratchet tool may comprise a handle extending along a handle axis and housing a motor, a head coupled to the handle at a first end of the handle, the head supporting an output shaft configured to be driven by the motor to rotate about an output axis, the output axis being substantially perpendicular to the handle axis, a ratchet mechanism coupled between the handle and the output shaft, the ratchet mechanism configured to restrict rotation of the output shaft in a first direction and to allow rotation of the output shaft in a second direction opposite the first direction, and a direction control configured to switch the first direction associated with the ratchet mechanism between a clockwise and a counterclockwise direction, the direction control being coupled to the handle and spaced apart from the head along the handle axis.

    Abstract: An impact tool is provided with vibration isolators to reduce vibrations felt by the operator gripping the handle of the tool. The impact tool has a hammer and an anvil that impact against each other during use. The impacts create undesirable vibrations in the tool housing and noise in the work area. The isolators are useful in minimizing such vibrations and noise.

    Abstract: A turbocharged compressor system using an Organic Rankine Cycle system to recover waste heat from a compression process. The Organic Rankine Cycle system circulates an organic fluid through an evaporator, where the organic fluid vaporizes and is expanded in a turbine section of a turbocharger to drive a compressor section of the turbocharger. The organic fluid vapor is condensed in a condenser and is pumped to the evaporator once again for recirculation. The compressor section of the turbocharger pre-compresses a working fluid before entering an airend in a compression system. As the working fluid exits the airend, it may be delivered to the evaporator, where the waste heat from the working fluid evaporates the organic fluid flowing in the Organic Rankine Cycle system. The working fluid may also be circulated between intercoolers in multi-stage compressor systems.

    Abstract: A diaphragm pump having a crankshaft that is rotatable about a rotational axis and coupled to a piston. The piston is reciprocally displaceable within a piston cylinder along an axis of motion between suction and discharge strokes. A diaphragm housing coupled to the piston cylinder at least partially defines a pumping chamber through which fluid is pumped as the piston reciprocates. The axis of motion, which intersects a connection between the piston and the connecting rod, may not intersect the rotational axis of the crankshaft such that, relative to an arrangement in which the axis of motion does intersect the rotational axis, a peak magnitude of piston side load forces during the discharge stroke is reduced and a peak magnitude of piston side load forces during the suction stroke is increased so as to attain an improved balance between the peak magnitudes of piston side load forces of the discharge and suction strokes.
