Title: Removal of minor impurities from crude partial oxidn. gas - by treatment with sulphided iron catalyst at relatively low temp.
Inventor: FIRNHABER BERNHARD DIPL CHEM D
IPC: B01J27/00
Filed: 1980-05-10
Abstract: A process is claimed for the purificn. of crude gas from the partial oxidn. (gasification) at a temp. of 1000-2000 deg.C of solid or liq. hydrocarbons. After removing dust, and before further treatment, the gas is passed pref. at a temp. of 90-200 deg.C and a pressure of 2-60 bar, over a catalyst contg. 2-65 wt.% Fe in sulphided form, to remove traces of N oxides, SO2 and O2. The catalyst may be added as Fe oxide or hydroxide, or mixed Fe, Cr oxide (Fe/Cr=5-15 wt./wt.) or gas purificn. catalyst contg. Fe(III) hydroxide. It is normally sulphided by the H2S in the crude gas. Used for the treatment of gases from e.g. the Koppers-Totzek gasification of coal, to be used finally as heating gas, synthesis gas, reducing gas etc. It prevents deposition downstream of S, Fe sulphide, or Fe nitrosyl complexes on gas compressor turbine rotors or interstage coolers, and of solid NO in the liq. N2-wash system. The catalyst is cheap. The treatment temp. is lower than in prior art processes, so a special re-heating of the gases is not required.

Title: Loop disconnect pulse regenerator circuit - has bridge rectifier and relay circuit with spark quenching across pulsing contact
Inventor: MERZ LOTHAR
IPC: H04M7/00
Filed: 1980-09-18
Abstract: The loop disconnect pulse regenerator is used for transmitting dial pulses from a PBX extension through to the exchange line. The circuit comprises a rectifier bridge (G1-G4) and relay (AR) circuit which responds to incoming ringing current from the exchange. For outgoing calls the exchange loop, between the exchange line 'a' and 'b' wires, is formed by a coil (AD/I), two relay contacts (1i,4i) and a second coil (AD/II) across the line. Whilst the pulse train is being transmitted, two further relay contacts (2v,3v) short circuit the coils (AD/I,AD/II) and the pulsing relay makes and breaks a loop contact (1i). A further contact (4i) breaks the loop circuit through one coil (AD/II) whilst pulses are being transmitted so that no parallel inductive path exists. Opening the same contact (4i) also puts a capacitance (C) resistance (Wi) spark quench circuit across the pulsing relay contacts (1i).
Patent DE-3044992-A1 (DE)
Title: Pressure die casting of metals - where feeder cavity is located in mobile die half so movement of injector is not impeded during final feeding of casting
Inventor: KLEIN FRIEDRICH PROF DR
IPC: B22D17/10
Filed: 1980-11-28
Abstract: A die employed for the casting of metal parts consists of a stationary half (a) and a mobile half (b). In die half (a) is an injector barrel contg. a plunger which drives molten metal through a feeder and runner into the die cavity. The die cavity forming the feeder is located in the mobile die half (b), and the tip of the plunger enters the feeder cavity. The dia. of the plunger is pref. larger than normal so die filling times are reduced. When the plunger enters the feeder ensures efficient feeding during the solidification of the casting. With conventional injector barrels, a solid skin of metal forms in the bore of the barrel at its outlet end, thus greatly increasing the pressure required to ensure adequate feeding during final solidification of the casting. The invention eliminates this problem.
