A cart for filling intermodal shipping containers with a bulk particulate material, such as grain, includes a hopper to receive the bulk material and a belt conveyor to deliver the material to the container. The conveyor is positioned external of the container and throws the material along an arcuate path to the opposite end of the container whereby the container is substantially filled without the need to extend the conveyor into the container. The cart is supported on wheels to be moved where needed. The cart can straddle a standard truck trailer carrying a container so that the container need not be removed from the trailer for filling. The conveyor height is variable to reach a container on a truck trailer or on the ground. The cart width can also be reduced for road transport.

An atmosphere control system for the cab of a self-propelled combine has its principal components arranged for series flow and mounted compactly on a rear portion of the floor of the cab. A pressurizing blower injects fresh air into an upstream filter chamber through a translational inertial precleaner which discharges any removed dust along with bleed air vertically downwards through the floor of the cab. A filter further cleans fresh air as it continues into the system, to pass through a heat exchanger and into circulation by a circulation blower and suitable ducting. Both precleaner and fresh air filter are accessible through a door in an outside wall of the cab.

The engine of a self-propelled combine is mounted in an enclosure having an inlet through which cooling air is drawn by an engine-driven fan. The air is filtered by a rotating disk-like screen mounted over the air inlet before passing through a radiator adjacent the inlet. A duct extends across the face of the disk from its center to periphery, changes direction and terminates with an open end adjacent the inlet side of the fan by-passing the radiator. The duct is also open adjacent the face of the screen so that the fan draws air through the duct, (some of the air being necessarily drawn from inside the screen as it passes the duct opening) so that foreign material filtered from the mass of cooling air being drawn through the unobstructed portion of the screen and held on the screen exterior surface is removed and carried through the duct. A trash knife rigidly attached to the periphery of the screen extends outwards parallel to the screen's axis of rotation. The knife is shielded by and travels within an annular channel-like shroud as the disk rotates. The shroud is connected with and intersects the duct so that as the screen rotates the knife passes through the duct, closely adjacent a shear bar supported there. The knife cuts or dislodges any foreign material lodged in the duct where it changes direction so that it may continue its passage carried by the air flow through the duct. A relatively flexible material with a high percentage open area is used for the filter element of the screen and is held taut by a compression spring pressing outwards on a thrust washer at the center of the screen to form it into a shallow cone.

A liquid cooling system for an internal combustion engine includes a conventional radiator and circulating system and pressure cap, the latter having pressure and vacuum relief valve components for limiting the maximum operating pressure of the system and for limiting negative pressures to avoid damage during cooling after engine shutdown. A second, temperature responsive, pressure relief valve provides a lower system relief pressure as long as the temperature of the coolant in the radiator top tank remains below a certain level. When that level is exceeded, a thermally actuated valve excludes the second pressure relief valve from the system and maximum operating pressure is then limited, at a higher level by the valving of the pressure cap. In an alternative embodiment, an infinitely variable pressure relief valve responsive to and controlled by changes in coolant temperature replaces the fixed second pressure relief valve and its thermal actuator. As the temperature of the coolant increases, the set point of the variable pressure relief valve also increases and the system relief pressure varies automatically with the coolant temperature over a range of pressures whose upper limit is significantly greater than the set point of the relief valve in the pressure cap so that maximum system operating pressure is still limited by the pressure cap.
