A spreader, in particular for winter service vehicles, for spreading out solid spreading materials includes a spreading-material container for receiving the solid spreading materials to be spread out, and at least one liquid tank arranged within the spreading-material container and having an at least partly flexible sheath and variable volume for receiving liquid. The spreader furthermore comprises a conveying device in a floor surface of the spreading-material container for conveying the spreading materials out of the spreading-material container. The floor surface of the spreading-material container is horizontal or almost horizontal, with the at least one liquid tank being arranged on or above the floor surface such that, upon an at least partial filling of the liquid tank, there is formed a sliding surface for the solid spreading materials to be spread out that is inclined toward the conveying device relative to the floor surface.

A bin wall cleaner for a sweep conveyors and augers for removing residual grain located near the bin wall out of reach of the sweep conveyor and providing sweep coverage for non-uniform bin walls. The bin wall cleaner has a grain engagement member that extends outwardly from the distal end of the sweep. A biasing member maintains the grain engagement member extended toward the bin wall. A wall engagement member is attached to the grain engagement member to ensure the bin wall cleaner tracks with the bin wall. The grain engagement member extends by pivoting or telescoping at least one blade.

The present invention provides a method for emptying a reactor containing at least one bed of spent catalyst particles, wherein the reactor comprises at least one dump tube that opens into the reactor. The method comprising the steps of: (a) causing a portion of the bed of spent catalyst particles to flow out of the reactor via the dump tube; and (b) extracting the remainder of the spent catalyst particles from the reactor by driving the remainder of the spent catalyst particles toward the opening of the dump tube using a removable device comprising at least one flexible extraction sleeve introduced into the reactor via the said dump tube and connected to an extraction system situated outside the reactor, the sleeve being provided on its external surface with protuberances and being able to move, inside the reactor, translationally and rotationally with respect to the dump tube.

A bin sweep system having a sweep auger and a brush, wherein the brush extends radially beyond the end of the sweep auger to contact the bin wall during operation of the bin sweep to sweep material away from the wall. The sweep auger rotates about a first axis and the brush rotates about a second axis.
