Abstract: High purity magnesium oxide is obtained from a magnesite-containing ore, the impurities of which include calcium compounds. The ore is first calcined and the resulting magnesium oxide is converted to magnesium chloride by leaching with an ammonium chloride solution. Calcium chloride is also produced at the same time. The resulting magnesium chloride and calcium chloride are treated with carbon dioxide to form calcium carbonate and magnesium carbonate which can be precipitated and filtered out of the resulting magnesium chloride solution. The magnesium chloride solution is then reacted with ammonium carbonate to produce a magnesium carbonate trihydrate crystal slurry containing ammonium chloride. The ammonium chloride is subsequently removed and returned to the ammonia recovery stage for leaching of the calcined magnesium oxide while the crystals are dried and decomposed into carbon dioxide and magnesium oxide.

Title: Method, circuit and device for eliminating the dc-voltage component of a capacitive ac-voltage divider
Inventor: SCHMITT ROBERT DIPL ING
IPC: G01R17/06
Filed: 1985-12-20
Granted: 1989-10-19
Abstract: In a method for the elimination of the d.c. voltage components of a capacitive a.c. voltage divider whose a.c. measuring voltage which may include a d.c. voltage component, is fed to a measurement transformer, the task is to be solved to remove as quickly as possible the d.c. voltage component of the a.c. measuring voltage also to the greatest extent possible without falsification of the reproduction of the middle or high voltage to be measured. This is achieved in that the a.c. measuring voltage (UM) is fed to a measuring amplifier (14) by way of two parallel lines (L1, L2) via a d.c. voltage blocking element (6). The a.c. measuring voltage (UM) is thereby fed directly by way of one line (L1) and the d.c. voltage component (UG) of the a.c. measuring voltage (UM) is determined in the other line (L2) in that the a.c. measuring voltage (UM) is subdivided into such small time sections (t) that an equal number of time sections is coordinated per cycle (T) or half cycle (T/2) and the a.c. measuring voltage is continuously integrated over a period (T) at the frequency (Tf) of the time sections (t). The thus-determined respective d.c. voltage value (UG) is fed to the measuring amplifier (14) in phase opposition to the original value and by way of the latter to the measurement transformer (16) (FIG. 1).

Abstract: A furnace for heating cylindrical charges, in particular billets, rods and tubes, features a transportation facility with a conveyance device which feeds the charges in the longitudinal direction through a treatment chamber, the cross-sectional shape of which is closely similar to that of the charge; the transportation device also features a jacking device which supports the charge such that, regardless of the charge diameter, the longitudinal axis of the charge is always at the same level in the treatment chamber. Situated in the walls of the treatment chamber are nozzle outlets which direct a heated jet of gas radially with respect to the longitudinal axis of the charge and onto the surface of the charge. The feeding of circulating hot gas to the supply channel for the nozzles takes place from both ends of the treatment chamber. A ventilator is situated above the mid point along the length of the treatment chamber and blows out both inlets to the feed channels.
