Abstract: Truck unloader apparatus, systems and methods are disclosed for unloading and/or conveying aggregate material. In some embodiments, a load-bearing truss of the truck unloader includes a ramp in a road transport configuration.

Abstract: In a method for the automatic control of blood pumps, an optimization of the blood flow is achieved by periodic speed interventions and flow changes thereby occurring, using a formed differential variable and a control algorithm. In addition, the location of possible flow resistances on the venous or arterial side can be ascertained.

Abstract: A method of transporting and storing an oilfield proppant is provided that includes transporting the proppant to a storage facility by use of a dump truck; providing a load assembly at the storage facility which comprises a load hopper and a load conveyor; transferring the proppant from the dump truck to the load hopper; and operating the load conveyor to transport the proppant from the load hopper to a proppant storage area of the storage facility to form an accumulation of stored proppant therein.

Abstract: An apparatus for unloading packages, parcels, postal items, baggage, etc., from a container having an open side. The apparatus has a sliding wall that is disposed over the open side of the container when the container is receiving within the apparatus. The apparatus, along with the container, is tilted such that the open side of the container is generally directed downward. From this tilted orientation, the sliding wall of the apparatus is withdrawn, incrementally exposing the open side of the container, permitting the controlled egress of the packages, etc., from the container.

Abstract: The invention is directed to an unloading system for shopping carts wherein a conveyor device is disposed in the entry area of a cash register or scanning apparatus, and acts on the products lying randomly in the shopping cart to subject them to a transporting motion in a defined unloading direction, whereby a side wall of the basket in this direction is to be opened.

Abstract: This invention relates to an apparatus for the aligning and/or sorting, and if applicable separating, individual parts in particular such parts that are connected to each other or remain adhered to each other. The apparatus comprises a machine frame and a first conveying device mounted thereon. A storage area for a disordered quantity of the individual parts is arranged in front of the conveying device and a linear second conveying device for the aligning and/or sorting the individual parts is arranged so as to follow the first conveying device. The storage area is exchangeably connectable to the conveying device, with the interposition of a docking device.

Abstract: A receiving assembly for a solid waste disposal system is provided. The assembly includes a pit defined by vertical side walls and having an upper opening. An upwardly inclined receiving conveyor is positioned within the pit. An infeed conveyor includes a first end positioned beneath the discharge end of the receiving conveyor such that solid waste material is dropped by the receiving conveyor onto the infeed conveyor. A heavy curtain is suspended above the discharge end of the receiving conveyor for controlling the fall of the solid waste material onto the infeed conveyor. A second curtain is positioned between the conveyors to prevent material from falling therebetween. The infeed conveyor is operated at about twice the speed of the receiving conveyor.

Abstract: A method and a system for forming a rod-like member into a three-dimensional frame structure, involving a work feed station for individually feeding a rod-like member, a bending station for bending the rod-like member having a prescribed length into a two-dimensional frame structure, a welding station for welding two mutually abutting ends of the two-dimensional frame structure of the rod-like member; and a forming station for plastically forming the two-dimensional frame structure into a three-dimensional frame structure. Typically, the two dimensional structure comprises a loop structure formed by joining two opposite ends of the rod-like member by welding, and the rod-like member consists of a pipe member. Thus, by welding the mutually abutting parts of the rod-like member together when it is formed into a two-dimensional frame, retaining the rod-like member for the welding is simplified as it involves the retaining of the rod-like member against its positional variations only in one direction.

Abstract: A chip sampling unit and method for obtaining a representative sample from a chip transporting unit such as a railcar or trailer.

Abstract: A feeder box for dumping bulk materials onto a conveyor of a mobile transfer station comprises at least one feeder device located adjacent a side of the conveyor, each feeder device including a box compartment and a support structure for the box compartment, the box compartment being pivotable with respect to the support structure so as to tilt towards the conveyor to dump bulk materials onto the conveyor.

Abstract: A barge tipper comprises a cylindrical floating apparatus 10 defining a chamber 18 into which a barge 28 can be floated. End doors 16 at either end of the apparatus 10 are closed and the barge 28 is clamped in position by hydraulically operated clamps 20. Water is pumped from the chamber 18 to ballast tanks 12 and 14, causing the apparatus to rotate and thus tipping the barge 28. The contents of the barge 28 flow into a first conveyor 22 and are delivered to a second circumferential conveyor 24 which feeds the material to an external conveyor 26.

Abstract: Method and apparatus for supplying wood fiber material in both roundwood and chip form to a pulp paper plant through a single off-loading station having a rotary railroad car dumper for unloading fiber material to a receiver box including a platform for receiving the fiber material transferred at an elevated position from the receiver box, a wall for guiding material being transferred onto the platform, and a plurality of plows for segregating the wood fiber material and for moving the roundwood and chip materials along the deck in separate directions toward separate conveying systems.
