  • Patent number: 9506236
    Abstract: A device for removing floating material from a liquid, especially from sewage, has at least one sieve element shaped like a filter basket, for example, that in a front side has an inlet opening through which liquid can flow into the interior of the sieve element. The device is equipped with a drive so the sieve element can rotate around a rotation axis. A collection device is arranged within the sieve element for collecting the liquid and/or floating material, in which case the collection device is attached to a pumping-out device for the liquid and/or the floating material. A process for removing floating material from a liquid, especially from sewage, uses a sieve device that contains at least one sieve element that may be shaped like a filter basket, for example, and is equipped with a drive so it can rotate around a rotating axis.

  • Patent number: 8168972
    Abstract: A method for simultaneous recrystallization and doping of semiconductor layers, in particular for the production of crystalline silicon thin layer solar cells. A substrate base layer 1 is produced, and subsequently, an intermediate layer system 2 which has at least one doped partial layer is deposited on the base layer. An absorber layer 3 which is undoped or likewise doped is deposited on the intermediate layer system 2, and in a recrystallisation step, the absorber layer 3 is heated, melted, cooled and tempered. Alternately, instead of an undoped capping layer, a capping layer system 4 which has at least one partial layer can also be applied on the absorber layer 3.
