摘要： A snow removal assembly includes a truck that has a cab and a box that is positioned behind the cab. A chute is coupled to the cab of the truck to receive snow on a road upon which the truck is driving. An auger is rotatably disposed in the chute to urge the snow outwardly through the chute when the auger is turned on. A snow pipe is coupled to the chute for delivering the snow into the box and a pump is integrated into the snow pipe for urging the snow through the snow pipe. A heating unit is integrated into the box and the heating unit is in thermal communication with the box. Furthermore, the heating unit heats the box when the heating unit is turned on for melting the snow into water thereby facilitating the water to drain outwardly through the drain in the box for disposal.

摘要： The building roof structure is arranged so that attachment of that structure to building support elements does not require penetration through such roof structure into the interior of the building. The panels overlap and the attachment of the panels to the building support elements occurs in the overlap areas so that elements are interposed between the attachments and the building interior.

摘要： An engine assembly includes an engine structure and an exhaust gas recirculation control valve supported on the engine structure. The engine structure defines a cylinder bore and intake and exhaust ports in communication with the cylinder bore. An internal exhaust gas recirculation passage is defined in the engine structure and extends from the exhaust port to the intake port and may overlie a central region of the cylinder bore. The exhaust gas recirculation control valve is at least partially located within the internal exhaust gas recirculation passage and is displaceable between an open position and a closed position. The open position allows exhaust gas flow from the exhaust port to the intake port through the internal exhaust gas recirculation passage and the closed position obstructs exhaust gas flow from the exhaust port to the intake port through the internal exhaust gas recirculation passage.
