Title: Retort furnace for the production of magnesium and the use of horizontal chamber coke oven
Inventor: KNIPFELBERG MANFRED
IPC: C22B26/22
Filed: 1998-06-30
Abstract: Retort furnace for production of magnesium The retort furnace is for production of magnesium by reduction of a charge (12) of oxidic magnesium, particularly dolomite lime, using a reduction agent, specifically ferrosilicon, at temperatures at least equal to 1000 degrees C in partial vacuum. The furnace has a horizontal chamber furnace with at least one retort chamber (3) extending over the length of the furnace. The retort chamber has walls made of a refractory material, and has a vacuum-tight sheet metal inner lining. There is a heating chamber on each side of the retort chamber, and condensers (9) to condense the magnesium vapour and to remove the condensed magnesium. These condensers can be joined to the charging openings (7) with a vacuum tight seal.
Patent CH-624538G-A3 (CH)
IPC: G04C9/08
Filed: 1979-04-04
Abstract: A time resetting operation in an electronic timepiece requires blocking of the stepping motor 1, and block of the mechanical type is avoided by the invention. A STOP switch 10 actuated by a time resetting stem of the timepiece sets to state "1" a flip-flop 11 which blocks gates 12 and 13 for controlling the passage of the pulses which drive the motor 1 through a feed circuit 2. The circuit 2 then passes a continuous current in the same direction as the last drive pulse. Thus, triggering of the continuous current leaves the position of the rotor unchanged. A counter 14 counts 1-second pulses and then resets the flip-flop 11, which causes the motor to resume normal operation. This avoids excessive discharging of the battery of the electronic timepiece if the user forgets to return the stem to its initial position after a time resetting operation.

Gasification takes place in a mixed flow composed of a counter flow, direct flow and transverse flow. A portion of the gasifying agent is introduced through an inclined grate in the form of a step grate and thrust grating and ash is removed at the bottom end of the grate. Fuel gas is drawn off above the upper level of the grate on the side opposite the lateral feed of the gasifying agent. The gasification apparatus is enclosed in a double-layer insulating/cooling system in which air is used as the insulator and coolant. The gasification process is regulated by the temperature profile of the gasification apparatus, the position of the principal gasification zone is adjusted by ash discharge, the gasification temperature is regulated by the flow of gasifying agent and the output is regulated by the width of the gasification zone. The fuel gas produced is used preferably for generating electricity in a work machine. Exhaust gases are purified preferably with the aid of an active coke filter.
