Abstract: The present invention relates to the novel isolated 12–30 strain of Pestalotiopsis microspora capable of producing novel antioxidant and antimycotic agents. The present invention also relates to the novel isolated 3,5,7 trisubstituted isobenzofuranone and derivatives thereof, methods of isolating the novel isobenzofuranone from cultures P. microspora 12–30, and to novel uses of the compound as an antioxidant and antimycotic agent. The present invention further relates to a novel 1,5,7 trisubstituted 1,3-dihydroisobenzofuran and derivatives thereof, methods of isolating this novel compound from cultures of Pestalotiopsis microspora 12–30, and to uses thereof.

Abstract: A die assembly for machines used to bend lengths of pipe for pipeline applications. The die assembly includes three major components, an exterior housing, a flexible die, and an eggcrate assembly. The exterior housing encompasses the flexible die and eggcrate assembly and pins into conventional bending machines. The flexible die includes a plurality of narrow plate segments positioned along a pair of tie rods. The plate segments are free floating and spaced so as to converge or diverge with respect to the direction of flex of the tie rods. The eggcrate assembly provides support for a plurality of spring plates. Each spring plate has a radius of curvature consistent with the amount of desired bend in the length of pipe.

Abstract: A broad spectrum biological herbicide comprises a mammal-sparing bioherbicide fungal mutant, e.g., a S. sclerotiorum mutant, of limited survival time and geographical dissemination characteristics under standard agricultural conditions. The invention also relates to a method of obtaining herbicides of the invention comprising obtaining viable wild type bioherbicide fungal spores, subjecting these to UV light to reduce the number of viable fungi to less than 5% the initial number of spores, selecting mutants which differ from the wild type in at least one characteristic such as altered phenotype or morphology, and further selecting a mammal-sparing bioherbicide fungal mutant of reduced survival time and geographical dissemination characteristics under agricultural conditions when compared with the wild type. The invention also relates to a method of using the broad spectrum biological herbicide to reduce the number of weeds in an area.
