Abstract: Provided is a power transfer unit, such as a power take-off unit including an input shaft coupled to an input gear for common rotation and axially movable relative to the input gear for engaging a coupling at a first end of the shaft with a drive component, a chamber formed between the input shaft and input gear, and a piston axially movable in the chamber, whereby the piston rotates with the input shaft. Due to the rotation of the piston with the input shaft, a power take-off unit is provided without the need for components to separate the piston from the input shaft.

Abstract: A lift control interface is operable to control and monitor a lift system. Each lift column in the system has such a lift control interface. The lift control interface allows a user to assign lift columns to a lift system. One or more of the assigned lift columns may be assigned to a column control group. The user may lock the selection of these columns. The status of the assigned, selected, and locked lift columns may appear on every lift control interface in the lift system. The user may govern operation of the selected columns in the column control group from a single control interface, such as any control interface at any of the selected columns. The lift control interfaces may include visual representations showing the relationships between the lift columns and a vehicle, such as with lift column icons being positioned around a vehicle icon.

Abstract: A split shaft transfer case includes a first housing portion and a second housing portion that are secured together along a plane of engagement to form an enclosure. An input shaft and an output shaft that are each supported for rotation about an axis of rotation that is generally parallel to the plane of engagement defined by the first and second housing portions. A first operating shaft is supported for rotation about an axis of rotation, and a first operating clutch selectively connects the first operating shaft to the input shaft for rotation therewith. A second operating shaft supported for rotation about an axis of rotation, and a second operating clutch selectively connects the second operating shaft to the input shaft for rotation therewith. The axis of rotation of at least one of the first and second operating shafts is movable relative to the axis of rotation of the input and output shafts.

Abstract: A system for operating a hydraulically actuated device that is provided on a vehicle includes a pump drive unit that is adapted to operate a hydraulic pump. The vehicle includes a drive train having a portion that engages the pump drive unit for operation. The system also includes an accumulator and a hydraulically actuated device. Lastly, the system includes a controller that causes the hydraulic pump to supply pressurized fluid to the hydraulically actuated device when a demand is requested by the user. The controller causes the hydraulic system to supply pressurized fluid to the hydraulically actuated device independent of whether the vehicle is moving or stationary.

Abstract: A system for detecting liquid in an inground lift has a tube with an open end disposed within the internal cavity defined by the containment housing of the inground lift. The tube is in fluid communication with a source of pressurized gas. A pressure sensor generates a signal if the pressure within the air line exceeds a predetermined level, which occurs if the end is blocked by liquid. A control system is configured to respond to the signal.

Abstract: An electrical receptacle cover is securable over an electrical receptacle. The cover includes a generally planar cover plate for positioning over the receptacle. The cover plate includes an outlet opening therethrough for accessing the outlet of the electrical receptacle. The cover plate also includes an aperture therethrough for passage of a threaded fastening element. A threaded nut-like securement member is formed integrally with the planar cover plate. The securement member is frangibly removable so that it may be attached to the receptacle for accommodating the fastening element extending through the cover plate.

Abstract: A cable tie bandolier for use with automatic tools. The bandolier includes a plurality of interconnected cable ties. The ties are interconnected by a single web positioned between adjacent ties and located closer to the head of the tie than to the tail of the tie.

Abstract: A cable tie bandolier for use with automatic tools. A continuous length of cable ties may be formed utilizing a non-continuous molding operation by molding discrete shots of cable ties, such discrete shots having connection capability therebetween allowing the connection of one discrete shot of cable ties to a second discrete shot of cable ties thereby providing one continuous strip of cable ties.

Abstract: A hanger bar assembly supports an outlet box between spaced apart support elements.

Abstract: An improved electrical ceiling box including a top portion bounded by a peripheral side portion, with a pair of diametrically opposed ear lugs rigidly secured to the side portion. Each ear lug has a pair of ears integrally formed therewith extending inwardly into the interior cavity of the box. A first ear fits within a recess formed in the bottom edge of the box, while a second ear extends through a slot formed in the side portion of the box.
