Title: Chemical browning bath for metals - where one electronic temp. comparator maintains bath at constant temp. and concn. by adding water when specified bath temp. is exceeded
Inventor: ZWEZ PETER
IPC: C23C22/73
Filed: 1980-03-22
Abstract: The bath is provided with heaters so it can be kept at its b.pt; and a temp. sensor is immersed in the bath to determine its actual temp. (Ta). The sensor feeds signal (Ta) to a controller, which is supplied with a desired bath temp. (Tref), and compares the two values. When Ta exceeds Tref, the controller switches on a pump so that water is fed into the bath, pref. from a water rinsing bath located next to the browning bath. The browning bath pref. has heaters employed to attain a temp. (To) which is below Tref. Once the bath has reached temp. (To), the heating power is reduced to a lower value. The controller pref. has a lamp indicating that Tref has been exceeded, and an acoustic alarm operated when Tref has been exceeded for a prescribed time. Used e.g. in a browning bath consisting of a 35% NaOH lye with optimum working temp. (Tref) of 142 deg.C. The invention holds both the operating temp. and the NaOH concn. constant, both essential factors if a constant colour is to obtd. on metals immersed in the bath.

Title: Three=phase static inverter with symmetric output voltages - uses oscillator to produce three reference vectors for three single-phase inverters
Inventor: FORSTBAUER WILHELM DR
IPC: H02M1/084
Filed: 1980-03-28
Abstract: The 3-phase inverter contains three single-phase static inverters connected in parallel at their inputs to the dc source. The output of each inverter is connected via a low pass filter to a transformer. The output windings of the three transformers are connected in star configuration to give the 3-phase output. Each inverter is controlled by a controller comprising a vector-orientated control circuit and a control unit. A vector oscillator forms a 3-phase, balanced system of reference vectors for the vector-orientated control circuits. The 3-phase output remains balanced under all load conditions. Each control circuit shifts the independent pulse raster of its associated inverter until its output voltage vector has the same phase as the reference vector produced by the vector oscillator. The 3-phase output voltages are symmetric in angle since the oscillator produces symmetric reference vectors.
