    Abstract: In at least one illustrative embodiment, a diaphragm pump may include a sleeve formed to include (i) a bore extending along a longitudinal axis and (ii) a sleeve port that opens to the bore, and a spool supported in the bore of the sleeve and formed to include a spool port, the spool being configured to move with a diaphragm during at least a portion of a stroke of the diaphragm such that the spool slides relative to the sleeve and, when the diaphragm reaches a turndown position that is between first and second end-of-stroke positions, the spool port aligns with the sleeve port to cause a pilot signal to be supplied to a cut-off valve. At least one of the sleeve and the spool may be rotatable about the longitudinal axis to adjust a location of the turndown position relative to the first and second end-of-stroke positions.

    Abstract: The present disclosure is directed to an instrumentation fitting with a liquid seal to prevent fluid leakage therefrom. The instrumentation fitting includes a connector configured to connect to an apparatus having a pressurized region with fluid therein. A sealing grommet is positionable within the connector and an extension tube is engageable with the sealing grommet within the connector. The extension tube is configured to extend to a height H above the pressurized region and fill with liquid to a height level h to provide a hydraulic head sufficient to equalize the pressure within the pressurized region.

    Abstract: The present invention provides methods and systems for a rotary impact device having an annular exterior surface for use with an impact wrench for providing torque to a fastener. The rotary impact device includes an input member having an input recess for receiving the anvil of the impact wrench, an output member having an output recess for receiving the fastener, and an inertia member. The inertia member is stationary and positioned on the exterior surface of the rotary impact device for increasing the torque applied to the fastener.

    Abstract: Illustrative embodiments of impact tools are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism including a hammer and an anvil. The hammer may be configured to rotate and to move between a disengaged position in which the hammer does not impact the anvil when rotating and an engaged position in which the hammer impacts the anvil when rotating, and the anvil may be configured to rotate when impacted by the hammer. The impact tool may further comprise an electronic controller configured to cause the hammer to (i) rotate in the disengaged position until reaching a threshold rotational speed and (ii) move from the disengaged position to the engaged position in response to the hammer achieving the threshold rotational speed.

    Abstract: A system, in certain embodiments, includes a centrifugal compressor diffuser including a flow path having a first surface and a second surface defining opposite axial sides of the flow path. The centrifugal compressor diffuser also includes multiple vanes extending from the first surface to the second surface of the flow path. A first profile of each vane varies along an axial direction. The centrifugal compressor diffuser further includes multiple vanelets extending from the first surface toward the second surface in the axial direction. A first axial extent of each vanelet is less than a second axial extent of the flow path. In addition, a second profile of each vanelet varies along the axial direction and/or the vanelets form a non-periodic pattern around a circumference of the flow path.

    Abstract: According to one aspect of the present disclosure, a control system and method of controlling a refrigerated dryer of a gas compressor system are disclosed. The control system, including a controller and a flow sensor, selectively operates in a power saving mode in which the controller shuts down a refrigerant compressor included in the dryer system when the flow sensor indicates that no compressed gas is flowing through the dryer. In a further aspect of the present disclosure, the control system uses input from a temperature sensor to determine whether to activate the compressor regardless of the flow of compressed gas through the dryer. Consequently, the control system enables the dryer to perform with aspects of both non-cyclic and cyclic dryers without the added cost and complexity of a conventional cyclic dryer.

    Abstract: A system, in certain embodiments, includes a plurality of detachable, three-dimensional diffuser vanes attached to a diffuser plate of a centrifugal compressor. In certain embodiments, the detachable, three-dimensional diffuser vanes may be attached to the diffuser plate using threaded fasteners. In addition, dowel pins may be used to align the detachable, three-dimensional diffuser vanes with respect to the diffuser plate. However, in other embodiments, the detachable, three-dimensional diffuser vanes may include a tab configured to fit securely within a groove in the diffuser plate. In addition, the tabs of the detachable, three-dimensional diffuser vanes may include indentions that mate with extensions extending from the diffuser plate, wherein the tabs may slide into slots between the extensions and the grooves of the diffuser plate.
