Patent NO-168123-B (NO)
Inventor: SHERMAN MICHAEL I
IPC: D21C9/12
Filed: 1986-05-28
Abstract: A method and apparatus are provided for increasing the efficiency of treatment of a paper pulp slurry with chlorine gas, such as in the bleaching or delignification of deciduous wood chemical pulps, coniferous wood chemical pulps, and non-wood fibrous chemical pulps. Chlorine gas is intimately mixed with the pulp in a fluidizing mixer (14), the pulp preferably having a consistency of about 7-12%, and then is passed to a retention vessel (20). The discharge of pulp from the mixer to the retention vessel, and from the retention vessel to other treatment structures, is throttled by valves (30, 31) so as to increase the pressure in both the mixer and the retention vessel to above atmospheric, and preferably in the range of about 15-150 psig (1 to 10 bar above atmospheric pressure). The chlorine gas is added to the mixer through one more discs (53) of porous materials having pore sizes in the range of about 5-175 microns, such as porous ceramic or sintered metal discs. The increased pressure during the chlorine treatment, and the introduction of the chlorine gas in the form of minute bubbles, improve the solubility of the chlorine in the pulp slurry and thereby increase the efficiency of treatment. (Figure 1).

Patent YU-43951-B (YU)
Title: Process for obtaining high purity magnesium oxide
Inventor: AINSCOW W S
IPC: C01F5/06
Filed: 1985-11-25
Abstract: High purity magnesium oxide is obtained from a magnesite-containing ore, the impurities of which include calcium compounds. The ore is first calcined and the resulting magnesium oxide is converted to magnesium chloride by leaching with an ammonium chloride solution. Calcium chloride is also produced at the same time. The resulting magnesium chloride and calcium chloride are treated with carbon dioxide to form calcium carbonate and magnesium carbonate which can be precipitated and filtered out of the resulting magnesium chloride solution. The magnesium chloride solution is then reacted with ammonium carbonate to produce a magnesium carbonate trihydrate crystal slurry containing ammonium chloride. The ammonium chloride is subsequently removed and returned to the ammonia recovery stage for leaching of the calcined magnesium oxide while the crystals are dried and decomposed into carbon dioxide and magnesium oxide.

Title: Methods and apparatus for mass spectrometry
Inventor: BATEMAN ROBERT HAROLD
IPC: H01J49/40
Filed: 2001-03-02
Granted: 2002-06-26
Abstract: A method is disclosed for identifying parent ions by matching daughter ions found to be produced at substantially the same time that the parent ions elute from a mixture. Ions emitted from an ions source 1 are incident upon a collision cell 3 which alternatively and repeatedly switches between a first mode wherein the ions are substantially fragmented to produce daughter ions and a second mode wherein the ions are not substantially fragmented. Mass spectra are taken in both modes, and at the end of an experimental run parent and daughter ions are recognised by comparing the mass spectra obtained in the two different modes. Daughter ions are matched to particular parent ions on the basis of the closeness of fit of their elution times, and this enables parent ions to then be identified.
