标题 :Synthesis of 16-unsaturated pregnanes from 17-keto steroids
发明人：HESSLER EDWARD J; VANRHEENEN VERLAN H
权利人:UPJOHN CO
摘要:17-Keto steroids (I) in their protected form (IIa or IIb) are reacted with a metalated olefin (VI) to give a 21-aldehyde (IV) which is readily transformed to a 16-unsaturated pregnane (V) which is useful in the production of commercially important substituted corticoids.

标题 :Polyhydroxybutyrate polymerase
发明人：PEOPLES OLIVER P; SINSKEY ANTHONY J
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:A method for controlling and modifying biopolymer synthesis by manipulation of the genetics and enzymology of synthesis of polyhydroxybutyrate (PHB) and polyhydroxyalkanoate (PHA) polyesters at the molecular level in procaryotic and eukaryotic cells, especially plants. Examples demonstrate the isolation, characterization, and expression of the genes involved in the production of PHB and PHA polymers. Genes encoding the enzymes in the PHB and PHA synthetic pathway (beta-ketothiolase, acetoacetyl-CoA reductase and PHB polymerase or PHA polymerase) from Zoogloea ramigera strain I-16-M, Alcaligenes eutrophus, Nocardia salmonicolur , and Psuedomonas olevarans were identified or isolated and expressed in a non-PHB producing organism, E. coli . Specific modifications to the polymers include variation in the chain length of the polymers and incorporation of different monomers into the polymers to produce co-polymers with different physical properties.

标题:Ink-jet printing device

摘要:The device comprises a plurality of ink reservoirs, each connected to a number of nozzles (22) equidistant along a corresponding row. The nozzles connected to the various reservoirs are spaced apart vertically by at least one line space. The device can be used for printing different lines in parallel, moreover subdividing the length of the line, or for printing different zones of the sheet in facsimile. The ink is kept in circulation between the reservoirs and the nozzles by a common peristaltic pump which acts by a series of actuating elements on the discharge ducts for the inks in the reservoirs. The reservoirs may contain inks of different colors to permit printing in different colors or polychrome facsimile printing by additive or subtractive synthesis of the colors. The ink is conductive and is kept at earth potential, while electrodes (23) disposed outside the corresponding nozzles (22) are energized selectively to produce sprays of particles of ink from the nozzles. The ink contains a mixture of a dye of direct or solvent or acid type with a solution of water, electrolytic compounds, moistening agents, thickeners, preserving agents and antifoaming agent. The ink is prepared by mixing the compounds under agitation, then mixing in the dye until a predetermined acidity is obtained and finally filtering it and sealing it in the pack in the absence of air.
