Title: Sinking of deep boreholes by rotary flushing - comprises lowering drill string contg. rotary drill end bit, into the hole then passing flushing fluid through the string
Inventor: BRUSSMANN DIETMAR
IPC: E21B17/16
Filed: 1990-12-15
Abstract: This is a method for sinking a deep borehole by the rotary flush method.  A drill string, consisting of a number of drill pipes hanging from a hook, is lowered into the hole. The bottom pipe carried a rotary drill-bit driven either by the drill string or directly. The drill string, through which a flushing fluid passes down to the bit, is weighted at its bottom end.  The string is divided into hydrostatically independent sections, each end of which is subjected to the hydraulic pressure of the flushing fluid in the borehole. The stirng is in tension, except around the weighted tool. A number of features of the method, and variants of the arrangement used, are claimed. USE/ADVANTAGE - In other methods of sinking deep borings, borehole deviations can be reduced but not eliminated, and the methods may be expensive. With this method, straight boreholes can be sunk without undue expense; the equipment is lighter and hook load is reduced.

Title: Reacting gas with molten material in narrow space - round lower end of axial gas feeder with enlarged internal buffer space
Inventor: FALLER KURT
IPC: B01J10/00
Filed: 1991-01-24
Abstract: An axial inlet for gas to react heterogeneously with a liq. or melt in a reaction chamber leads directly into a buffer space defined by a large lower end to the gas inlet surrounded by the reaction space attainable via a narrow gap round the foot of the buffer space wall. The reaction space is considerably smaller than the buffer space, and is entered by gas rising through an inclined sieve plate. After reaction, gas leaves from an upper outlet. The outlet for reacted melt or liq. may (like the main reaction chamber) be surrounded by a heater jacket and include a sieve plate in the jacketed area. ADVANTAGE - Liq. cannot be drawn into the gas feeder, which for melts which could solidify and block the feed is highly important.
