Abstract: A processing station for two-dimensional substrates including at least two processing units and at least two conveyor lines for substrates arranged in parallel to another, wherein both the processing units are placed between the two conveyor lines, and an arrangement for moving the substrates from the conveyor lines to the processing units and back is provided. The arrangement includes four linear conveyor units each having at least one substrate support, wherein a first linear conveyor unit leads from the second conveyor line to the first processing unit, a second linear conveyor unit leads from the first conveyor line to the first processing unit, a third linear conveyor unit leads from the first conveyor line to the second processing unit, and a fourth linear conveyor unit leads from the second conveyor line to the second processing unit.

Abstract: A screen bowl centrifuge having first and second conically diverging screen sections. And a method of separating solids from liquid of a slurry includes feeding a slurry from a conveyor hub to a cylindrical section of a bowl extending about the conveyor hub; scrolling the solids along the cylindrical section in a first direction and a majority of the liquid in a second direction opposite the first direction using at least one helical blade extending from the conveyor hub; and sliding the solids from the cylindrical section along a conically diverging screen section of the bowl that includes a first conically diverging section and a second conically diverging section, the first conically diverging section extending at a first angle to the axis and the second conically diverging section extends at a second angle to the axis, and the first angle is different from the second angle.

Abstract: A method of conveying imprint material and a printing table for a flatbed printing machine are described. The method of conveying imprint material, particularly solar cell wafers, in and out of a processing area of a flatbed printing machine includes the steps of moving the imprint material by means of a conveyor belt on a first conveyor belt section into the processing area, processing the imprint material and further moving the imprint material on the first conveyor belt section out of the processing area. An automatic checking of the first conveyor belt section for soiling or damage takes place and, as a function of the checking result, a moving-back of the first conveyor belt section into the processing area or a moving of a second conveyor belt section into the processing area takes place.

Abstract: It is a finding of the present invention that a user of a broadcast receiver gets text information significantly more quickly if a reference to another text information object in the broadcasting signal is contained in a text information object included in the broadcasting signal, which is currently displayed on the display of the broadcast receiver, and the user is enabled to cause the text information to be displayed to be changed from the text information of the current text information object to the text information of the text information object to which the current text information object refers by simple operation of a user selection means. Here, the additional effort is very limited since in today's broadcast receivers there mostly is an “unoccupied” key, which only has an assigned function and thus is occupied in special situations of use of the broadcast receiver, and may be used as user selection means, as far as that goes.

Abstract: A solid bowl screw centrifuge including: a drum having a solids discharge at a conical end and at least one discharge opening at an end opposite the conical end, the at least one discharge opening arranged with an axial drum lid; a screw rotatable at a different speed relative to the drum; a centripetal chamber section connected behind the drum lid with the at least one discharge opening; a centripetal pump arranged to discharge a liquid phase from the solid bowl screw centrifuge; and an adjustable throttling device connected in front of the centripetal pump in the centripetal chamber section, the adjustable throttling device being assigned to the at least one discharge opening.

Abstract: A flatbed printing machine includes at least one adjustable side stop in an infeed area for the medium to be printed. The side stop is arranged between an infeed area edge and a feeder edge over which the medium to be printed is carried. The side stop is adjustable in a guide parallel to the infeed area edge and to the feeder edge. A link belt is provided, which link belt is capable of tracking the side stop and covering a gap that would otherwise occur between the infeed area edge and the feeder edge.
