Title: Purificn. of gasification prods. - by treatment in venturi washer with molten mixt. of tin contg. aluminium and/or copper to remove sulphur cpds.
Inventor: HUEBNER K DIPL CHEM DR RER NAT
IPC: B01D47/00
Filed: 1978-09-11
Abstract: The parent patent described the pressurised purificn. of gasification prods. in a conventional type of washer via moltent metal according to DT 2605249; and a venturi washer is pref. employed. The novelty is that the liq. metal consists of a mixt. of tin with aluminium and/or copper; and the tin content of the molten metal mixt. pref. exceeds 50%. The process uses a mixt. of Sn with Al and/or Cu to achieve lower costs while also increasing the efficacy of the purificn. process. The Al has high reactivity, while the Cu prevents kinetic inhibition of reactions at relatively low temps. (under ca. 850 degrees K). The result is that H2S and simple mercaptans react with the molten metal mixt.

Title: Multiple-frequency sine wave generator - derives corresp. carrier frequencies from parent oscillator output using digital frequency dividers
IPC: H04L27/12
Filed: 1978-09-29
Abstract: Further frequency dividers (FT1) are used to produce additional pulses (I2-Ik) from the output voltage of the parent oscillator or of a pulse generator (IG) with random text sequence. The additional pulses are blended into the output pulses of the parent oscillator in front of the frequency dividers under the control of the pulse generator. The pulse generator (IG), sets the AND-gate (G2-GK) free, according to the polarity of its output signal and applies the appropriate pulses (I2-IK) for each carrier frequency (f1 to fk). The appropriate pulses (I2 to Ik), before blending are held in a pulse shaper for an intrinsically-set time period of DELTA T.
