Patent CA-2205739-A1 (CA)
Title: Removal of nitrogen oxides from gases
Inventor: WENNING ULRIKE
IPC: C07C7/148
Filed: 1997-06-13
Abstract: For selectively removing nitrogen oxides from a carrier gas that contains hydrocarbons, the nitrogen oxides are removed by chemisorption on metal oxides, without the occurrence of undesirable secondary reactions. The metal oxides are preferably formed from metals of the 6th to 8th subgroups, whereby manganese dioxide (MnO2) is especially preferred as a metal oxide. The process can be conducted with one or more reactor beds, which preferably operate at 10 to 40°C and are regenerated with nitrogen at a temperature of 130 to 170°C. By removing nitrogen oxides from an olefin-rich gas, for example from the waste gas of an FCC unit, the resultant gas can then be fed to a cryogenic olefin extraction stage without danger of explosion. Such a waste gas contains unsaturated hydrocarbons, hydrogen, carbon monoxide, and oxygen, the oxygen having a concentration preferably between 100 and 5000 mol ppm.

Patent CA-2218311-A1 (CA)
Title: Gage for measuring length of flexible extrusions
Inventor: MALIK RICHARD
IPC: G01B5/02
Filed: 1997-10-10
Abstract: A roller measurement fixture is comprised of a series of small in-line rollers (20) mounted in one or more rows, forming a receiving cradle device (25).  An extruded part to be measured is cradled in a semi-circular arrangement of the rollers and straightens as it settles under its own weight. The cradle device will accommodate many different cross-sections of extruded seal.  The rollers are free to rotate as the part is placed into the fixture and properly located.  Friction from these rollers is negligible, therefore the part remains in, or attains, its free state, without internal stresses, throughout the loading and measurement process.  Thus, the extruded part is limp within the cradle, being loaded so as to contact a head or alignment stop at one end of the cradle. A floating stop (35) riding on the rollers engages the other end of the part and cooperates with a scale (30) on the cradle as a means of acquiring the measurements.

Title: Method of operating a combustion unit of a coal-fired power plant with a slag tap furnace and a combustion plant operating by this method
Inventor: SPIELMANN HORST
IPC: C10L10/00
Filed: 1996-09-12
Abstract: The flue dust conveyed by the flue gas in the combustion plant of a coal-fired power station still contains up to 50 % combustible material. In order to attain high efficiency by full burning, in modern coal-fired power stations with slag tap firing the flue dust is returned to the combustion chamber. This increases the average time spent by a particle of coal or dust in the firing circuit. The invention provides a process for operating a combustion plant of a coal-fired power station operating on the slag tap firing process and a combustion installation operating thereby with a slag tap in which a titaniumcontaining material is conveyed in addition to the coal to accelerate the full burning of the coal. The fuel throughput is thus increased, resulting in an increase in the efficiency of the power station.
