摘要： An auxiliary system with purge control automatically supplies diesel exhaust fluid (DEF) to an onboard DEF tank of a diesel engine to enable prolonged unattended operation. The system includes an auxiliary DEF tank, an auxiliary DEF supply line, a controller, a pump, an air inlet, and a three-way valve configured to switch the pump inlet between the auxiliary DEF tank and air. In response to low-level DEF, the pump delivers DEF through the supply line to replenish the onboard DEF tank. The controller may automatically calculate onboard DEF tank volume based on the delivered volume of DEF, and DEF level data received from an ECM, to enable replenishment control regardless of engine make and model. In response to high-level DEF, engine stoppage, or other system fault, the controller switches the valve to air and runs the pump for a predetermined time to purge DEF from the supply line. The auxiliary system may be skid-mounted, portable, and configured to supply DEF to multiple diesel engines.

摘要： A support structure for a float pan for floating a concrete surface provides an interface between the float pan and a rotating machine. The support structure is characterized by a hub configured for concentric attachment to a rotor, and by trusses that extend radially from the hub, each providing a float pan contact surface and means for attachment to the float pan. Perimetric bracing links the trusses about the perimeter of the support structure. A machine similar to a walk-behind or ride-on trowel but without rotor blades, may incorporate the support structure and operate as a dedicated power flotation machine. Under weight of the machine, the contact surfaces of the trusses conform the float pan to a desired shape or radius of curvature for optimizing a flotation process.

摘要： Disclosed is a simultaneous twin pitch adjustment system that includes a flexible shafting cord operatively connected to first and second couplers. The couplers are supported by posts and are operatively connected to pitch communicators. A handle is supported by each post and is configured such that manipulation of the handle translates to adjustment of the pitch of an associated rotor blade assembly. When the simultaneous twin pitch adjustment system is engaged, manipulation of one handle further translates, via the flexible shafting cord, to adjustment of the pitch of another rotor blade assembly in an amount essentially equal to the amount the associated rotor blade assembly is adjusted.

摘要： A digital control system for monitoring and controlling a concrete pumping system. A microcontroller provides control signals and receives feedback from associated comparator switch subsystems. Feedback from the comparator switch subsystems is used by a microcontroller to determine whether short circuit or open circuit malfunctions are occurring on solenoids valves attached to the output of the comparator switch subsystems. Said control system exhibits an electronic control means to control the admittance or interruption of current through said solenoids. Individual solenoid status is sent to a graphical display where an operator views said display to diagnose failure modes. The microcontroller further monitors the establishment of temporal initial conditions and limits operational pump activity until said temporal conditions are met.

摘要： A swiveling ball joint assembly set into a center of a driver plate to be used with a grinding head includes a rigid housing having a socket and a flange extending outwardly. An elongated shaft defines a rotational axis having a ball end enclosed within the socket and a coupling end to be connected with a spider arm. A bearing is concentrically aligned with the rotational axis and rotatably attached to the elongated shaft. A mounting hole to allow connection by fastener to a driver to translate rotational motion from the spider arm to the driver. A protective boot extends from the socket to a shelf to prevent foreign material from contaminating the socket.

摘要： A driver interface for a grinding head includes a center plate having top and bottom surfaces, an outer edge, a mounting channel in the top surface, and mounting pads on the bottom surface, each pad having a raised edge. An upper clamping plate is inserted within the mounting channel. A lower clamping plate defines disk locating apertures and fastens to the bottom surface of the center plate so that each of the disk locating apertures surround the raised edge of a mounting pad. The upper and lower clamping plates are removably fastened to the center plate. A disk attacher having an anchoring portion and a disk receiving portion bends around the outer edge of the center plate so that the upper clamping plate when fastened to the center plate clamps the anchoring portion between the upper clamping plate and the mounting channel, and so that the lower clamping plate when fastened to the center plate clamps the disk receiving portion to a mounting pad and within one of the disk locating apertures.

摘要： A self-propelled power trowel for finishing a concrete surface is equipped with reversible rotors to allow an operator to reverse the direction of rotation of rotor blades. The trowel includes a rigid frame adapted for operation over a concrete surface, a pair of rotor assemblies having rotor blades tiltably connected to the rigid frame for frictionally contacting the concrete surface and supporting the rigid frame thereabove, a prime mover mounted to the rigid frame and operatively coupled to drive the rotor blades of the rotor assemblies in opposite rotational directions. Synchronous or hydraulic motors are configured for causing, responsive to manual controls, reversal of the direction of rotation of the rotor blades.
