Patent FI-94498-C (FI)
Inventor: BRASEL GREGORY M
IPC: B22F9/08
Filed: 1991-02-01
Granted: 1995-09-25
Abstract: Shaped parts are formed from a powder having the desired chemistry of the finished part by mixing the powder with a thermosetting condensation resin that acts as a binder. The resin may be partially catalyzed, or additives or surfactants added to improve rheology, mixing properties, or processing time. Upon heating, the inherently low viscosity mixture will solidify without pressure being applied to it. A rigid form is produced which is capable of being ejected from a mold. Pre-sintered shapes or parts are made by injection molding, by using semi-permanent tooling, or by prototyping. Binder removal is accomplished by thermal means and without a separate debinding step, despite the known heat resistance of thermosetting resins. Removal is due to the film forming characteristic of the binder leaving open the part's pores, by providing oxidizing conditions within the part's pores as the part is heated, and by insuring that the evolving resin vapor diffuses through the pores by heating the part in a vacuum.

Abstract: Alkali metal delta manganese dioxide hydrage, which is obtained as a by-product in the industrial oxidation of organics by KMnO4 is subjected to ion exchange reaction with rare earth ions of the ceria subgroup (viz. cerium, lanthanum, etc.). By employing favorable temperature and pH conditions, a reaction product can be produced containing as little as 0.03 moles of alkali metal per mole of manganese, and up to one mole of ceria rare earth per six moles of manganese. The separated product is prepared for catalytic use in the form of dried porous pellets. The resulting oxidation catalyst has high efficiency, long life, and optimum activity at reasonable temperatures. The catalyst can be used advantageously for applications such as the oxidation and deodorization of exhaust gases from paint drying ovens.

Abstract: This invention relates to an electrolysis process and cell for producing a metal by electrolyzing halides in a molten salt bath. It consists of using one cathode in the form of a basket, simultaneously passing a current I1 between this cathode and the anode in such a manner as to carry out a first deposit of crude metal in the basket and a current I2 between the said basket and the complimentary cathodes for depositing the final metal thereon. The cell consists of a central anodic system, a tubular cathodic basket surrounding the anode and a series of cathodes surrounding this basket, a positioning which can be reversed in relation to the basket. The invention finds its application in the continuous production of good quality refractory metal with a suitable material and electric yield.

Abstract: Staphylococcal enterotoxins obtained by secretion from Staphylococcus aureus, by expression of enterotoxins in other bacteria or cells, or by chemical mutagenic treatment of S. aureus strains are used in treatment of cancer as tumorcidal agents.  Enterotoxins (A, B, C, D, E and F) can be administered via simple intravenous injection at dosages between 0.5 µg/kg body weight to 150 µg/kg. Non-steroidal, anti-inflammatory agents and prostaglandin synthesis inhibitors such as ibuprofen may be simultaneously administered to attenuate toxic reactions from the enterotoxins. Streptococcus pyrogenic exotoxin and alpha hemolysin, which nave structural and functional homology to the enterotoxins, are also useful in tumoricidal treatment. The enterotoxin gene transfected into tumor cells resulting in a tumor cell with surface expression of the minor lymphocyte stimulating locus with consequent patent activation and proliferation of T lymphocytes especially those with V.beta. specificity, would also be useful in this application.
