摘要:
A life expectancy management system which comprises: a storage means which is capable of storing data, such as genetic data, birth data, lifestyle data, pediatric health data, and adulthood health data; a means for altering the data based upon the occurrence of at least one event selected from the group consisting of: chronic and routine health events, emergency health events, pregnancy data and medical advancements; and a prediction modeling logic which provides a predetermined life expectancy that can be reduced by deviations from expectations which are calculated from the data and altered or adjusted data. Optionally, a means for providing recommended goals based upon the life expectancy predicted and the predetermined life expectancy.

This invention is a fuel composition for use in internal combustion engines comprising a major amount of a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, and greater than 5% by weight based on the total composition of an oxygenate selected from the group consisting of a saturated, aliphatic monohydric alcohol having on an average from 8 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons, and mixtures of the alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5% by weight of oxygen. The oxygenate significantly reduces particulate emissions from the exhausts of diesel powered engines.

According to one embodiment of the improved process of this invention, dicobalt octacarbonyl is produced in an olefinic medium by contacting an aqueous solution of a tetracarbonylcobaltate metal salt with an oxygen-containing gas in the presence of an olefinic extractant for dicobalt octacarbonyl to oxidize the tetracarbonylcobaltate anion to dicobalt octacarbonyl which is efficiently extracted into the olefinic phase, thereby producing an organic phase which can then be recovered and passed to a cobalt-catalyzed olefin hydroformylation reaction zone as source of at least a portion of the catalyst and olefin required in the olefin hydroformylation reaction to form the corresponding aldehydes. According to another aspect of this invention, an aqueous solution of tetracarbonylcobaltate metal salt is contacted with an oxygen-containing gas in the presence of gaseous carbon monoxide, and optionally also in the presence of an organic solvent for the dicobalt octacarbonyl, to efficiently oxidize the tetracarbonylcobaltate anion to dicobalt octacarbonyl.
摘要:
The tracking problems of prior art optical monitoring (e.g., feedback stabilization) schemes are substantially alleviated by positioning a photodiode (PD 130) directly in the light path of the optical source (100) to be stabilized. The active (light-absorbing) layer (104) of the PD samples (absorbs) only a small portion of the light beam (140) emanating from the source and converts that portion to a photocurrent used in a feedback loop (120, 101) to control the excitation supplied to the source. The remaining, major portion (140') of the beam is transmitted unabsorbed through the PD active layer to utilization means (e.g., through an optical fiber 108 to a remote receiver). Advantageously, in one embodiment the PD is a double heterostructure (DH) in which the photocurrent is linearly related to the beam intensity. The use of discrete or integrated lens means (110, 110', 164, 166) to enhance coupling from the source to PD is described. In addition, tandem DH-PDs (150, 152) are also described which perform both detection, for demodulating encoded information at one optical frequency, and sampling, for feedback stabilization at another optical frequency.
摘要:
Opposite sides of an article are irradiated to sterilize the article. The cumulative irradiation should be above a first value, and below a second value greater than the first value, at all of the positions in the article to provide the article with desired radiation benefits. Any amount of cumulative radiation between the first and second values is considered as optimal values. For a first range of article thicknesses, the cumulative radiation in the article is at the optimal values. For article thicknesses in a second range greater than in the first range, the cumulative radiation at positions in the article is greater than the optimal values. For article thicknesses in a third range greater than the second range, the cumulative radiation at the different positions in the article is at the optimal values. For the thicknesses in the second range, a member disposed in the radiation path weakens the radiation passing to the article, thereby reducing the cumulative radiation to an optimal value. For each thickness in the second range, a different amount of cumulative radiation above the optimal value may occur when the member is not disposed in the radiation path. The member may accordingly be provided with different thicknesses, dependent upon the amount of the cumulative radiation in the article for the different positions in the second thickness range, to reduce the cumulative radiation in the article to an optimal value. A system may automatically position the member properly for article thicknesses in the second range.

This invention is a method of reducing particulate matter emission from internal combustion engines which use a diesel fuel composition comprising a major amount of a diesel fuel having a base fuel which contains no more than 10% by weight of olefins and no more than 10% by weight of esters, by admixing said fuel with greater than 5% by weight based on the total composition of a saturated, aliphatic monohydric alcohol having on an average from 4 to 20 carbon atoms, one or more ketones having on an average 5 to 25 carbons and mixture of said alcohol(s) and ketone(s). The amount of the oxygenate in the fuel composition is sufficient to provide the fuel with at least 0.5% by weight of oxygen. The oxygenate significantly reduce particulate emissions from the exhausts of diesel powered engines.
