Title: Receptor:release ligand (reland) complexes and assays and kits based thereon
Inventor: FITZPATRICK JUDITH
IPC: G01N33/536
Filed: 1996-06-19
Abstract: Receptor:release ligand complexes and kits based thereon are used in a method for assaying for the presence of analyte in a sample, by detecting a released component of the complex ~ receptor or ligand. The complexes are stable in the absence of analyte, but unstable when contacted with the analyte, leading to release of the ligand. The term "release ligand" or "reland" is applied to such a ligand. Either the released ligand or released receptor is detected by means of a detection system carried by either. The receptor:ligand complex may be formed in situ or may be pre-formed.

At least a portion of the air is discharged  into  the  atmosphere  for  mixing  with  the flammable gas in a swirling pattern immediately adjacent to the  flammable gas which prevents  internal burning  and premature failure of the flare apparatus.
Patent CA-2230218-A1 (CA)
Inventor: HARANDI MOHSEN NADIMI
IPC: B01D53/86
Filed: 1996-08-09
Abstract: Oxides of nitrogen (NOx) emissions from an FCC regenerator (30) are reduced by operating the regenerator (30) in partial CO burn mode to produce flue gas with more CO than O2 and with NOx precursors. This flue gas is then enriched with controlled amounts of oxygen and charged over catalyst, preferably Group VIII noble metal on a support, to convert most NOx precursors to nitrogen.  Flue gas may then be charged to a CO boiler (89). Eliminating more than 90 %  of NOx emissions is possible by operating the FCC regenerator (30) in partial CO burn mode, then adding air and catalytically converting NOx precursors at substoichiometric conditions. Conversion of NOx if formed in the regenerator (30) may be achieved as well.

Inventor: WAI CHIEN M
IPC: C22B3/16
Filed: 1996-11-04
Abstract: A method of extracting metals directly from metal oxides by exposing the oxide to a supercritical fluid solvent containing a chelating agent is described.  Preferably, the metal is an actinide or a lanthanide. More preferably, the metal is uranium, thorium or plutonium. The chelating agent forms chelates that are soluble in the supercritical fluid, thereby allowing direct removal of the metal from the metal oxide. In preferred embodiments, the extraction solvent is supercritical carbon dioxide and the chelating agent is selected from the group consisting of .beta.-diketones, halogenated .beta.-diketones, phosphinic acids, halogenated phosphinic acids, carboxylic acids, halogenated carboxylic acids, and mixtures thereof. In especially preferred embodiments, at least one of the chelating agents is fluorinated. The method provides an environmentally benign process for removing metals from metal oxides without using acids or biologically harmful solvents. The chelate and supercritical fluid can be regenerated, and the metal recovered, to provide an economic, efficient process. Also disclosed is a method to separate a desired metal from impurities formed during a supercritical extraction process based on solubility differences between the components, and the ability to vary the solvent power of the supercritical fluid. The use of adduct forming agents to separate metal in such processes is further disclosed.

Abstract: For  the  purpose  of  optimizing  the  power consumption and yield of chemical reactions in the case of silent discharge and of improving the dissipation of heat, the interspace between a first electrode (1) and a second electrode (2);of a discharge reactor is filled up by a block (4) of rigid open-pored material having a porosity of preferably 80-90%,  the skeleton of which block may consist,  for example,  of glass,  quartz  or ceramic.  The  clear  width  of  the  pores,  in  which microdischarges are formed, represents an effective gap width critical for the progress of the silent discharge and may  be  set  at values  of,  for  example,  between 0.05 mm and  0.2 mm which  are  optimal  for the power consumption.   As   a   safeguard   against   breakdown, moreover,   a   barrier   layer   (5)   consisting   of nonconductive  solid material may be provided between the electrodes (1, 2).        For specific uses, for example the reaction of CO2 and H2 to form methanol and water or of CO2 and CH4 to form synthesis gas, the skeleton may be coated with a  suitable  catalyst  which,  in the  cases  mentioned, contains,  for example,  Cu and ZrO2 or Cu and ZnO or nickel compounds.

Abstract: A ripening room (10) for controlled produce ripening includes side walls (18 and 20). The room (10) receives two rows of boxed produce (26) spaced to define an interstitial volume (50) therebetween. Each row of product (26) is spaced from one of the side walls (18 or 20) to define a side airspace (24) therebetween. The room (10) also includes air control units (32).
