Polyvinyl alcohols in combination with glyoxlated-vinyl amide polymers as yankee dryer adhesive compositions

Abstract: Improved creping compositions comprising glyoxylated vinylamide polymers in combination with polyvinyl alcohol are disclosed.

Interchangeable tip-open cell fluorometer

Abstract: Described and claimed is an interchangeable tip-open cell fluorometer comprising a housing and a fluorometric probe tip interchangeably connected to the housing, the probe tip including a probe tip housing defining an open cell and enclosing a probe optical arrangement, the probe optical arrangement including an excitation source and a fluorescence detector wherein the excitation source is aimed directly into the fluorescence detector such that a sample can be fluorometrically detected. Also claimed is a method of using this interchangeable tip-open cell fluorometer for detecting fluorescent signals emitted by one or more fluorophores from samples from a natural or industrial water system. The fluorometer, when coupled with a controller, is capable of monitoring and optionally controlling an industrial process or system.

Polyaldehyde/polyacetal compositions

Abstract: OF THE DISCLOSURE Water-soluble monomers and water-soluble polymers derived therefrom are disclosed. These materials can be used with other vinyl monomers to form water-soluble polymers which are reactive with cellulosic substrates to obtain drastically improved strength, particularly when applied in paper manufacture. The polymers contain at least two mole percent of a monomer represented by the chemical structure: wherein R is -H, -CH3, or -C2H5; and A is 0, or N(R1); and B is CH2, CH2CH2O, ?CH2?n N(R1) (CH2?m, ;and ;and wherein R1 is -H, -CH3, -C2H5, (CH2CH2O)nH, or (B)qD, and wherein q is from 1-6, except when B contains nitrogen in which case q is always one; and wherein R2 is -H, -CH3, -C2H5, or (CH2CH2O)nH; and wherein R3 is
