标题 :Synthesis of critical temperature of a turbine engine
发明人：WINDISH DAVID K; HARRIS JAMES D; MCDANIEL DARIN J
权利人:ALLIED SIGNAL INC
摘要:A critical parameter for a device is generated as follows. The critical parameter is modeled. When the device is operated under steady-state conditions, the modeled parameter is corrected by a measured parameter known to be accurate under steady state operating conditions. The correction accounts for errors which may be present in the synthesis of the critical parameter and normal anticipated performance variation of the device. When the device is operated under transient conditions, however, the correction of the modeled parameter is based upon previous steady-state conditions. Thus, the apparatus generates a theoretical parameter during transient operating conditions.

标 题 :Process for extracting water and energy from synthesis gas
发明人：HAND JOHN W
权利人:MINTECH CORP
摘要:Synthesis gas is produced, at moderate to high pressure, by reacting steam and oxygen with a solid carbonaceous material, and the gas is then saturated under pressure, with water obtained both from drying the carbonaceous material and from scrubbing the gas in aqueous solutions of alkali salts to remove inpurities. The pressurized, water saturated synthesis gas is then cooled and dried by passing it through an expansion turbine, followed by a condensor of the tube and shell type. The expansion turbine is mechanically coupled to one or more rotary compressors, which recompress the noncondensable components of the synthesis gas stream passing through the condensor to a pressure suited for subsequent catalytic synthesis of methanol, methane or ammonia. Work extracted from the moist synthesis gas stream by the expansion turbine, is used for recompressing the dry synthesis gas, for compressing air for manufacturing oxygen used in the synthesis gas generator, or for producing an electric current or other purpose.

摘要:In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.
