Abstract: A system for removing debris from an agricultural harvester includes a flow splitter supported relative to an outlet of a chopper assembly of the harvester such that the flow splitter at least partially extends within a stream of processed crop material discharged from the chopper assembly. The flow splitter is configured to divide the stream of processed crop material into separate crop material flows for receipt within an extraction chamber of the agricultural harvester.

Abstract: The invention provides a method to extract organic compounds from aqueous mixtures, using a specially selected organic compound as an extraction liquid. The method can be applied to remove compounds such as acetic acid or ethanol from complex aqueous mixtures, including fermentation reactions or broths, and can be used for in situ extraction of products or by-products from a fermentation reaction. Some suitable extraction liquids for use in these methods include diethylene glycol dibutyl ether, tripropionin, and di(ethylene glycol) diisobutyl ether.

Abstract: This invention relates to crystalline pharmaceutically acceptable salts of an alpha 1a adrenergic receptor antagonist, Compound A, which are useful in the treatment of benign prostatic hyperplasia. Pharmaceutical compositions employing the crystalline salts, and processes for making and using the crystalline salts and pharmaceutical compositions of Compound A are also disclosed. This invention further relates to a process for obtaining enantiomerically pure intermediate useful for the synthesis of end product alpha 1a adrenergic receptor antagonists. The end product compounds are useful for the treatment of benign prostatic hyperplasia and for relaxing lower urinary tract tissue. The invention also relates to a process for preparing a class of dihydropyrimidinone compounds of which Compound A is a member, wherein the process involves deprotonating a dihydropyrimidinone compound and then coupling the deprotonated derivative with a primary amine.

Abstract: Asymmetric bioreduction of a ketone substrate with yeast produces the corresponding (R)-alcohol of structure: ##STR1## a key intermediate in the synthesis of a .beta..sub.

Abstract: Compound 9 is prepared by a 9-step ##STR1## process in an overall yield of about 35% from 3-acetylpyridine. Compound 10 is prepared by a seven-step ##STR2## process in an overall yield of about 30% from 3-acetyl pyridine. These compounds are key intermediates in the synthesis of Compound 11, an important .beta.-3 agonist useful in the treatment of obesity and diabetes.

Abstract: The present invention relates to a process for converting a racemic mixture of 3,3-diethyl-4-[(4-carboxy)phenoxy]-2-azetidinone esters into the corresponding (S)-acid using lipase derived from Pseudomonas sp. The process provides the target acid in high enantiomeric excess.

Abstract: The present invention provides a process for the stereoselective reduction of phenylalkyl ketones to their corresponding (S)-hydroxy compounds. The process utilizes the novel microorganism Microbacterium MB 5614 to effectuate the chiral reduction. The present invention also provides said novel Microbacterium, which has been deposited with the ATCC and assigned the accession number ATCC 55557.
