Title: Electric oven with swinging control panel - has timer with double row number drum to suit two panel positions
Inventor: FRIEDLAENDER HANS WERNER
IPC: F24C7/08
Filed: 1976-12-22
Abstract: The electric oven has a swinging flap (1) acting as a control panel, at the top, below the cooking surface, which can be pushed inwards to conceal all the control knobs (9). In this position it is vertical, and when pulled out, it swings through 45 deg., so that the face carrying the knobs then slopes downwards towards the operating side, also at 45 deg..

Title: Gasification of solid fuels in molten copper bath - with removal of sulphur by reaction with the copper
Inventor: WEIGEL HORST DIPL ING
IPC: C10J3/57
Filed: 1978-03-25
Abstract: Prodn. of cracking gas (CO/H2) mixts. from fuels, e.g. powdered coal, by reaction with a gasifying medium in a molten copper bath, by simultaneously passing the reactants through the molten metal. The copper removes sulphur by reaction to Cu2S and addn. of a basic solid to form a slag, as required when a molten iron bath is used, is eliminated together with associated disposal problems. Lower temp. (around 1200 degrees C) is required, which reduces heat losses and the product gas temp. Copper has better heat conductivity than iron and takes up around 20 wt.% of S. It reacts readily with O2 providing a high availability of O2 in the melt for reaction with fuel, and giving ideal conditions for CO formation. After use it is readily regenerated by blowing O2 through the melt.
