Title: Separation of heavy metals from waste water of the titanium dioxide industry
Inventor: SCHINKITZ DIETER
IPC: C02F1/54
Filed: 1992-10-01
Granted: 2000-01-18
Abstract: For economical and assured separation of chromium, vanadium and titanium ions from acidic waste waters, which accrue in great quantities in preparation of titanium dioxide, the pH is first raised to around a value of 3 by addition of a calcium and magnesium compound, preferably through addition of dolomite brick powder. Directly thereafter, the pH is fine tuned into the range of 4.3 to 4.7 through addition of calcium hydroxide and/or sodium hydroxide, and the hydroxides are separated with the aid of a flocculating agent. Since iron ions and calcium ions remain mainly dissolved in the waste water through such selective precipitation, only a relatively small volume of slush has to be disposed of.

Title: Switching power supply
Inventor: INOU KIYOHARU
IPC: H02M3/335
Filed: 1993-04-27
Granted: 1998-02-10
Abstract: A square waveform voltage is supplied to a second output circuit of a switching power supply.  The second output circuit utilizes a FET, and by controlling the width of a pulse chopped from the square waveform voltage, obtains a direct current output voltage having a set value.  However, if there is a time delay in a control signal for driving the FFT on/off, fast switching operations cannot be followed and controlled.          Also, due to this delay in the control signal, the width of the pulse is limited, and it is difficult to obtain a high secondary output voltage.  In the present invention, by providing an auxiliary power supply and a synchronizing signal generator for generating a synchronizing signal having a special waveform, a switching power supply can be realized in which the delay time of the control signal is reduced, and a high secondary output voltage can be obtained.
