摘要:
N-[Heterocyclicaminocarbonyl]-1H-indene and tetrahydronaphthalene sulfonamides, such as 2,3-dihydro-N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-1H-indene-4-sulfonamide, are useful for the regulation of plant growth and as preemergent and postemergent herbicides.
摘要:
Polybenzimidazoles are prepared in the form of small particles by reaction of bis(o-diamine) substituted compounds with dicarboxylic acids or of o-diamino-substituted carboxylic acids in the presence of an inert, nonsolvent, liquid medium and polyphosphoric acid.
摘要:
Oligomeric formal diols are prepared by coupling segments of PTMEG, each having a molecular weight of 1000-3000, with formaldehyde. The formal diols are useful in preparing polyurethanes.

1-Difluoromethyl-6,7-methylenedioxy-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid and certain of its alkylaminoalkyl esters, useful in treating bacterial infections in mammals.
摘要:
Thermally stable, rigid dibasic acids of the formula ##STR1## where R is ##STR2## where R.sup.1 is arylene or substituted arylene, are used to prepare thermally stable, rigid polyesters of the formula ##STR3## WHERE R.sup.2 is arylene or substituted arylene, and n is at least 10.
摘要:
This invention relates to dispersions of gold and a certain inorganic binder in an inert liquid vehicle, useful in the electronics art for producing conductor patterns adherent to substrates. Small amounts of the binder are effective in producing excellent adhesion to substrates, such as ceramic substrates. The binders comprise certain amounts of the crystalline materials PbF.sub.2, Cu.sub.2 O, and CdO, in addition to a glass of, by weight, 45-52% PbO, 3-6% B.sub.2 O.sub.3, 30-35% SiO.sub.2, 4-6% TiO.sub.2, 2-4% ZrO.sub.2, 0-1% ZnO, 1-4% Na.sub.2 O, 0-4% CdO, and 0-2% Li.sub.2 O.
摘要:
A bulked dimensionally stable yarn composed of a plurality of crimped and straight filaments randomly disposed throughout the cross-section of the yarn, said crimped filaments provide bulk and said straight filaments provide dimensional stability.
摘要:
Carriers are disclosed for supporting a plurality of agricultural cores on a plurality of core supports for coating by a flexible film. The plurality of core supports may include a pedestal for supporting a respective agricultural core and a core periphery region having a plurality of bridge elements which couple the pedestal to the connecting structure between the plurality of core supports. The carriers may include a vacuum system that independently communicates a partial vacuum to an aperture in each respective pedestal and a plurality of apertures in the core periphery region of a respective core support between the bridge elements.
摘要:
The invention provides DNA compositions that relate to transgenic insect resistant maize plants. Also provided are assays for detecting the presence of the maize DAS-59122-7 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.
