Abstract: The present application relates to apparatus (400, 500) for measuring an impedance of an electrical load (300) that is configured to be coupled to a controlled current source (200). The apparatus (400, 500) comprises a first coupling node (402) configured to be coupled to a first terminal (302) of the load (300) and a second coupling node (404) configured to be coupled to a second terminal (304) of the load (300). The apparatus further comprises a transformer (406) having a primary winding (408) and a secondary winding (410) and a capacitance (412) connected in series between a first terminal (414) of the secondary winding (410) and the first coupling node (402). A second terminal (416) of the secondary winding (410) is connected to the second coupling node (404). The apparatus further comprises a processing unit (424) is configured to control an excitation signal that is applied to the primary winding (408) so as to cause a variation, corresponding to the excitation signal, in an input current of the load (300), measure the input current and an input voltage of the load (300), and, based on the measured input current and input voltage, determining the impedance of the load (300).

Abstract: A centrifugal compressor impeller includes a plurality of blades on a front side that extend from a first axial side to an outer radial end of the impeller. The centrifugal impeller includes a back side having a nonlinear backwall. The backwall can include a flat area hear a bore of impeller, a flat area near a tip of the impeller, and a convex surface between the flat areas of the bore and the tip. In some forms the impeller further includes a concave surface between the convex surface and the tip to form an s-shape. A transition or inflection point can denote the change from convex to concave. The convex and/or concave surfaces can take any variety of forms such as constant radius sections and/or compound curves.

Abstract: An impact tool is provided which includes a drive source configured to rotate an output drive. A hammer is movable in a first direction to apply a rotational impact force on an anvil which rotates the output drive. A first hammer angle sensor set to a first signal channel and located proximate to a surface of the hammer. A plurality of regularly spaced targets are located on the surface of the hammer. Each of the plurality of regularly spaced targets are detectable by the first hammer sensor. And detection of one or more of the plurality of regularly spaced targets by the first hammer sensor indicates movement of the hammer.

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 hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

Abstract: A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

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. A ratio of the pad between the thickness and diameter of a central passage can be set to achieve the change in bearing characteristic.

Abstract: A compressed air drying system is provided for removing moisture from compressed air. The dryer operates in two modes in response to the demand for compressed air. In a first mode of operation, a refrigeration compressor runs continuously and the speed of a condenser fan is varied to maintain a constant cooling temperature. In a second mode of operation, the refrigeration compressor runs intermittently between on and off periods. As result, the cooling temperature fluctuates during the second mode of operation.
