IPC: B62D5/07

Abstract: A system for controlling fluid flow from a source (10) to a steering motor (25) and one or more auxiliary motors comprises a priority valve and a steering controller. The priority valve has a housing that includes an inlet port (46) connected to the source, a priority flow outlet port (48) an auxiliary flow outlet port, and a pilot port (52). A biasing spring urges the priority valve spool toward a priority position directing all flow from the inlet port to the priority port. The priority valve includes a pilot flow conduit directing a pilot flow of fluid through an orifice to the pilot port. Pressure upstream of the pilot flow orifice acts on the priority valve spool in opposition to the spring, and pressure downstream of the pilot flow orifice acts on the valve spool in addition to the spring. The steering controller has a load sense cavity communicating with a load sense port, and a neutral vent orifice which, when the steering controller is in neutral, communicates said load sense cavity with a return port for allowing a pilot flow of fluid from the pilot port of the priority valve to flow through said steering controller to the reservoir. Upon actuation from its neutral position, the steering controller substantially restricts flow through the neutral vent orifice to the reservoir before its main flow control orifice opens. As a result, pressure at the downstream side of the pilot flow orifice of the priority valve substantially increases before the main flow control orifice opens and assists the spring to quickly urge the priority valve spool to its priority position. When the main flow control orifice is open the load sense cavity of the controller is connected to the downstream side of the main flow control orifice so that pressures across the priority valve are varied with pressure variations across the main flow control orifice in accordance with operator demand and steering load.

Abstract: An improved container (10) for bulk cargo is provided with a peripheral wall (12, 14, 18), a top (30), and a bottom (20). The top (30) defines a longitudinally extending central ridge (31) and the bottom (20) defines two spaced, parallel, longitudinally extending skirts (34, 36) separated by a central recess (28). The contour of the top (30) generally corresponds to the contour of the bottom (20) such that multiple containers (10) can be stacked one over the other. The container (10) is provided with a perforated floor which simultaneously braces the peripheral wall (12, 14, 16, 18) against spreading and provides a support surface for palletized cargo and the like. The floor perforations allow bulk cargo to fall from the upper portions of the container to the lower portions of the container (10). A bulk cargo loading door (44) is provided in the top (30) along the uppermost portion of the central ridge (31), and two bulk unloading doors (46) are provided along the lowermost portions of the skirts (34, 36). In addition, end doors (48) are provided for moving palletized cargo into and out of the container (10). The container of this invention can be transported on a railway car of the type having an elongated central spine shaped to fit within the central recess (28) of the container (10). This railway car defines four container attachment structures (114), each of which supports the container (10) at a point well below the uppermost level of the spine. In this way, the center of gravity of the container (10) is kept low and close to the ground.

Abstract: The outer container has a wide pair (21) of side walls with carrying tabs (50, 51) which are attached via a pair (35) of folding lines. The carrying tabs (50, 51) consist of a closure part (52, 53) for closing the opening at the top of the container and a carrying part (54, 55) having a grip cutout (56, 57) in each case. On the narrow side, the liner has a tab (16, 17) in each case which has a centrally arranged and longitudinally extending slot (18, 19). When the folded container has been newly closed, closure tabs situated below the carrying tabs (50, 51) are arranged on the narrow pair (24) of side walls, which tabs are provided with tear-open weakening lines in a known manner. When the container is closed again, the carrying parts (54, 55) of the carrying tabs (50, 51) are placed against one another and the tabs (16, 17) of the liner are pushed over the carrying parts (54, 55) by the slots (18, 19) and hooked into the notches (58a, 58b; 59a, 59b). Thus the carrying parts (54, 55) are held in their position and the closure parts (52, 53) are pressed onto the opening, by which means the container is securely closed and can easily be carried. <IMAGE>

Abstract: The unit is used in radio and television sets with capacitance diode tuning. The control voltage for the capacitance diodes is picked up from a plurality of helical resistors arranged next to one another, in which in each case one slider (6) slides along on a resistance area consisting of a homogeneous resistance layer. All resistance areas are then jointly arranged next to one another in parallel on one substrate (1), in which arrangement they are electrically connected to one another by means of start and end rails (2, 3) with good conductivity. To reduce the temperature drift to a minimum, it is proposed to use a common large-area resistance area (4) for all helical resistors. <IMAGE>
