Abstract: Oven for non-metal melting, in particular silicon melting, with a housing enclosing an interior, at least one mould arranged in the interior for receiving a non-metal melt, at least one electrical heating device enclosing, at least partially, the at least one mould for influencing the temperature of the non-metal melt, and a power supply device connected in an electrically conductive manner to the at least one heating device for providing the heating device with a time-variable current I(t), wherein the current I(t) has a frequency of 0.1 Hz to 1000 Hz and the current I(t) is of a magnitude sufficient for setting a predetermined temperature of the non-metal melt, the currents in the plurality, where necessary, of heaters having a defined phase position in respect of one another.

Abstract: An apparatus for conveying and simultaneously turning objects has a first conveyor device for conveying the objects into the area of two conveyor-turning stations and a second conveyor device for conveying the objects out of the area of the conveyor-turning stations. The conveyor-turning stations have a conveyor that rotates horizontally and at least one turning device for contacting and turning the objects. The two conveyor-turning stations are used for alternate conveying of the objects along a common conveyor path. Each conveyor-turning station can be driven by its own electric motor with controllable speed. In an access area of the conveyor-turning stations, there is a device for detecting the position of the next object to be contacted and to be conveyed by the respective conveyor-turning station.
