Title: Horizontal continuous casting - using mould with end plate axially moveable in oscillating axial lining
IPC: B22D11/047
Filed: 1973-06-27
Abstract: In a process for horizontally continuously casting metal of thermal conductivity 0.25 cal/cm2/cm/C/sec., molten metal passes from a holding vessel into a mould having an axial water-cooled lining closed at one end with an end plate.

Patent NL-8104486-A (NL)
IPC: C04B11/02
Filed: 1981-10-02
Abstract: Calcium sulphate dihydrate is recrystallized into anhydrite with the aid of H2SO4 at elevated temperature in several steps.
