Patent DE-2223238-A1 (DE)
Title: Mould emptying - using counterweighted loading shell and interlocks
Inventor: BIEKER FRANZ
IPC: B29C45/76
Filed: 1972-05-12
Abstract: When the moulding is ejected into the loading shell, its rigid support ensures that it does not rock and give a false weight reading. If the weight is sufficient to overcome finely-adjusted counterweights, then interlocks are released and the shell is opened to let the moulding pass through, as its weight shows that no matter has been retained in the mould which could affect subsequent moulding operations. If the weight is too low, then the counterweight keeps the shell closed, and the machine stops, indicating that the mould is not clear on ejection.

Patent DE-2424199-A1 (DE)
Title: Electric furnace for continuous refining of magnesium - has central chamber filled with molten salt for removal of slime
Inventor: KOSAREW SERGEJ P
IPC: C22B26/22
Filed: 1974-05-17
Abstract: A furnace for refining metal (e.g. Mg) has a refractory lined bottom and a vertical partition which divides the furnace into a central chamber surrounded by peripheral chambers. The central chamber has a removable cover and is sealed from the peripheral chambers by a molten salt mass during furnace operation. All the chambers communicate in their lower sections and each peripheral chamber communicates with another at a level in the furnace so as to ensure consecutive overflow of refined metal from the first to the last peripheral chamber. The roof of the furnace has an opening for charging and for discharging the refined metal. The design ensures centralised slime removal and hence diminishes magnesium, inert gas and heat losses. As the central chamber only accommodates molten salt there is no need to interrupt the process when removing the slime. The use of the partitions ensures a furnace which is more reliable in service. Because there is no difference in melt levels, stresses are not produced which would damage the partitions, allowing the furnace height and capacity to be raised. Such furnaces require less attendants and auxiliary equipment.
