Title: Method of biotreatment for solid materials in a nonstirred surface bioreactor
Inventor: KOHR WILLIAM J
IPC: C22B11/00
Filed: 1996-05-14
Abstract: A method of biotreating a solid material to remove an undesired compound using a nonstirred surface bioreactor is provided. According to the method, the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 µm. A  nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated substrates into a tank so that the void volume of the reactor is greater than or equal to about 25 %. The reactor is inoculated with a microorganism capable of degrading the undesired compound in the solid material, and the solid material is then biotreated in the surface bioreactor until the undesired compound in the solid material is degraded to a desired concentration. The process is useful for bioremediation of contamined soils, the desulfurization of coal and the biooxidation of refractory sulfide ores and concentrates.

Title: A simple and efficient method to prepare technetium-99m labelled peptides
Inventor: WISHART DAVID
IPC: A61K38/00
Filed: 1997-12-19
Abstract: In an effort to develop better methods for preparing 99m Tc-labelled peptides for radioimaging and radiodiagnostic applications, we have developed a simple solid phase synthetic approach that allows the mercaptoacetyltriglycine (MAG3) technetium chelate to be attached directly onto the growing peptide chain using conventional solid phase peptide chemistry. This novel approach permits the facile, high yield preparation of precisely labelled and very pure (>95%) peptide-chelator conjugates. We believe this method has a number of significant advantages over other widely used protocols. In particular, it reduces the number of purification steps, eliminates the need for solution-phase conjugation and avoids the problems of non-specific chelator conjugation. Tests involving two different MAG3-bombesin conjugates, prepared using this technique, show that the peptide-conjugates can be efficiently labelled with 99mTc (92%), are highly resistant to cysteine challenge, are very stable in plasma and can bind to the desired cellular targets. This suggests that the protocols described here should be generally applicable in the preparation of other 99mTc labelled peptides.

Patent CA-2248389-A1 (CA)
Inventor: OBERL NDER IRMTRAUD
IPC: F02M33/00
Filed: 1998-09-25
Abstract: Surface reactors for propellants operate with a copper/tin alloy and convert unsaturated hydrocarbons at low concentration into tin organics which are extremely highly ignitable and therefore act as ignition nuclei in the combustion of propellants. The device has a reactor vessel through which the propellant or fuel is conducted. The reactor vessel holds granular material having an oxide-free surface and disposed in a native or man-made medium preventing the oxidation of the granular material. The inlet and the outlet of the device lie in the same plane. The efficiency of the system is improved because incoming and outgoing propellant or fuel is brought into countercurrent heat exchange and, in addition, a heating system is provided which can be switched as required, with the result that the device for forming the desired ignition nuclei is operated in a favorable temperature range. The process includes forming the granular material in a tin alloy melt with a solution-activating alloying constituent, and then quenching it in an oxidation-preventing medium of the granular material so as to produce a particle size of up to 3 mm diameter and a large surface area. Alternatively, the melt from which the granules are formed may simply be cooled to form the granules. The granular material is not subject to aging with regard to its action as a metallic reaction partner in propellants and fuels, as a result of which the efficiency of the granular material is wholly maintained during its entire lifetime.
