Title: Elimination of sulphur and sulphur cpds. from gases - by treatment with aq. suspension of catalytic material partic. active carbon
Inventor: JOHNSON HERBERT SKULI
IPC: C01B17/05
Filed: 1979-07-31
Abstract: Gas is treated to eliminate S vapour, droplets of liq. S and mixts. of H2S and SO2 contained in the gas in small amts., by bringing it into intimate contact with an acid aq. suspension of a finely divided catalytic material e.g. alumina or pref. active carbon. Catalytic material is then regenerated by (1) sepg. it from the aq. medium; (2) passing downwards through this material a fluid which can be either a liq. or a gas which does not react with the catalytic material, at a temp. sufficient to dissolve the S if the fluid is a liq., or to melt and volatilise it if the fluid is gaseous, and for sufficient time to separate the S from the catalyst. The regenerated catalytic material can then be re-used, in aq. suspension. Process is used partic. to treat gaseous effluent from the Claus process. The catalytic material can be regenerated so that it regains almost all its initial activity without appreciable loss of catalyst.

Patent DE-3014472-A1 (DE)
Title: Low switching loss transistor regulated DC power supply - uses shunt transistor to establish current in inductor in series with output capacitor leaving no transistor current during switching
Inventor: KERSCHER MAX
IPC: H05B41/28
Filed: 1980-04-15
Abstract: Direct current is obtained by rectifying an AC voltage. A positive DC rectifier terminal is connected, through a charging inductor, to a diode supplying an accumulator inductor in series with the accumulator capacitor, and also to a shunt transistor connected across the supply. The transistor provides a path for DC to flow from the rectifier through the charging inductor when switched on. The voltage developed over a resistor in the accumulator circuit drives a controller via a delay circuit. The control circuit drives the base of the transistor which, when it switches off, forces the charging inductor current to be directed to the accumulator capacitor. The controller prevents the switching of the transistor until the charging inductor current has fallen to zero. In this way the transistor carries no current during switching and the switching losses are minimal.
