Abstract: The invention relates to a moving system (100) for moving workpieces that are provided for gear cutting on a workpiece spindle (200) and have a workpiece axis of rotation, from a first position (A), taken up while they are being fed, into a third position (C) that differs from the first position by at least a smaller distance between the workpiece axis of rotation and the workpiece spindle axis, having a first movement unit (36, 32, 34) which moves a workpiece from the first position into a second position (B), different from the first and the third position, along a first movement path (AB), and a second movement unit (35) which moves the workpiece from the second position into the third position along a second movement path (BC), wherein the moving system is also designed to move machined workpieces back out of the third position and to hold and move more than one workpiece at the same time, wherein, while it is being moved on the first and on the second movement path, the workpiece is held by one and the s

Abstract: The invention relates to a moving system (100) for transposing workpieces that are provided for gear cutting on a workpiece spindle (200) and have a workpiece axis of rotation, from a first position (A), taken up while they are being fed, into a second position (C) that differs from the first position by at least a smaller distance between the workpiece axis of rotation and the workpiece spindle axis, having a first movement unit (36, 32, 34) which transposes a workpiece from the first position into a third position (B), different from the first and the second position, along a first movement path (AB), and a second movement unit (35) which transposes the workpiece from the third position into the second position along a second movement path (BC), wherein the moving system is also designed to transpose machined workpieces back out of the second position and to hold and move more than one workpiece at the same time, wherein, while it is being moved on the first and on the second movement path, the workpiece is

Abstract: A valve for controlling the flow of solids comprises a vessel having an overflow point, an inlet line for discharging solids into the vessel positioned within the vessel such that the inlet line's discharge point is lower than the vessel's overflow point, and apparatus for introducing a fluidizing fluid into the vessel. The fluidizing fluid fluidizes the solids within the vessel so that they overflow at the vessel's overflow point. For the removal of nuclear waste product the vessel may be placed within a sealed container having a bottom connected transport line for transporting the solids to storage or other sites. The rate of solids flow is controlled by the flow rate of the fluidizing fluid and by V-notch weirs of different sizes spaced about the top of the vessel.
