Abstract: ABSTRACT           In a process for manufacturing alcohol by fermen-tation employing immobilized microbial cells, a single fermenter is used for both the immobilization of microbial cells by gellation and the fermentation of yeast in order to avoid contamination by various germs.  A second fermenter may be employed for further fermentation of culture liquor from the first fermenter to obtain a high yield of alcohol. The removal of flocs of microorganisms and various germs is also useful for maintaining a high yield of alcohol.

Abstract: ADAPTIVE FILTER UPDATE NORMALIZATION            Abstract Loop gain normalization is employed in adaptive filters to control weighting of the filter characteristic updates in order to converge properly to a desired filter characteristic.  Filter stability and rapid high quality convergence is realized for a variety of received or inputted signals by employing both long term and fast attack estimates of a prescribed input signal characteristic to normalize the update gain.  In one embodiment, both long term and fast attack input signal power estimates are generated and one of the two estimate values is selected to normalize the update gain. Specifically, the fast attack estimate is modified by a predetermined value and, then, the larger of the long term estimate and modified fast attack is selected to normalize the update gain.

Abstract: PROCESS FOR IMPROVING POLYMER FIBER PROPERTIES AND FIBERS PRODUCED THEREBY                  Abstract of the Disclosure A method is provided for treating active hydrogen atom-containing polymer fibers or fibrous structures made thereof to permanently improve the antistatic, hygro-scopic, dye receptive, soil release, inter-fiber adhesion and bonding, and fabric hand properties of the fibers and structures.  The method involves contacting the fibers with an aqueous solution containing at least one unsaturated monomer and having an acid pH and a temperature between about 75°C and about 100°C.  After allowing the solution to uniformly disperse among the fibers, so that the monomer intimately contacts the fiber surfaces, the fiber is affected and has essentially single molecule addition of the monomer pendent to the polymer chain to form a branched polymer, graft polymerization of the monomer on the fiber surface is initiated by a polymerization initiator for the monomer, and the polymerization is continued for a sufficient time to allow substantial graft polymerization of the monomer on the fibers to modify the surface properties of the fibers.  The fibers are preferably scoured prior to the treatment process, and after polymer-ization the fibers are rinsed to remove acid and excess homopolymer prior to dyeing and/or further processing of the fibers.  The fibers may be in the form of knitted, woven or nonwoven fabrics, and may include amine-containing and/or hydroxy-containing polymers such as nylon, wool, silk, cotton, cellulosic, acetate and combinations thereof.

Abstract: CATALYZED COLORIMETRIC AND FLUOROMETRIC   SUBSTRATES FOR PEROXIDASE ENZYME          DETERMINATIONS            Abstract of the Disclosure Improved, catalyzed substrates for use in developing characteristic colors or florescence in the presence of peroxidase enzymes (e.g., horseradish peroxidase) are disclosed which in-clude as a rate accelerator a substituted phenol such as a p-halogenated phenol.  The complete substrate typically includes a peroxide type oxidizing agent (e.g., hydrogen peroxide), a chromogenic or flurogenic compound (e.g., ABTS), a buffer and the accelerator compound.  Advanta-geously, the accelerator should provide at least about 50 percent rate enhancement for the sub-strate, as compared with an otherwise identical, accelerator-free substrate reacted under the same conditions; however, the most preferred accelera-tor, p-iodophenol, gives enhancements on the order to 1,000 percent.  The substrates are particularly useful in so-called ELISA determinations which involve an enzyme-linked moiety, and permit detec-tion at very low concentration levels unobtainable with conventional colorimetric substrates.
