Patent DE-10359554-A1 (DE)
Title: Assembly for carburizing metal workpieces, in a vacuum furnace, matches the gas feed to the carbon take-up at the workpiece
Inventor: LOESER KLAUS
IPC: C23C8/18
Filed: 2003-12-17
Abstract: For the carburization of metal workpieces, in a vacuum furnace with a carbon carrier, the carburization is split to deliver pure carbon under process conditions. The acetylene volume flow is high at the start of the carburizing phase, and then reduced according to measurements of the concentration of hydrogen and/or acetylene and/or the total carbon. A sensor measures the exhaust gas, with a signal flow to a computer (PC) and/or amplifier, in turn connected to the dosing valve (V) in the gas feed. The assembly matches the gas feed to the carbon take-up at the workpiece.

Title: Salt melt-drilling process to sink 2 m boreholes for highly active waste disposal
Inventor: FOPPE WERNER
IPC: E21B7/18
Filed: 1995-01-19
Abstract: Salt-melt drilling process for continuous or intermittent, fully automatic sinking, also produces a solidified bore hole casing after penetration.
