Abstract:
A system and method for pathogen control in reprocessing of foods are disclosed. The system and method use chlorine dioxide to eliminate pathogens from carcasses as the carcasses are passed through a spray cabinet. According to one embodiment, chlorine dioxide solution is recirculated and reapplied to the carcasses in the spray cabinet.
Abstract:
This invention relates to process for coating a metal surface, wherein said process comprises contacting the metal surface with a barrier coating comprising (a) an amine salt of a fatty acid or an amine salt of a derivative of a fatty acid, (b) a salt of a non polymeric aromatic acid, (c) optionally, a nonionic or anionic surfactant, and (d) water. The invention further comprises a process for cleaning a metal surface containing residues, which comprises contacting the metal surface, exposed to the barrier coating, with water to remove residues that have deposited after applying the barrier coating to the metal surface.
Abstract:
The invention detailed herein comprises a family of novel multifunctional acrylate ionomeric resins, which are water-dispersible, and have built-in photoinitiator. The inventive resins are made self-photoinitiating by their reaction with beta-keto esters (e.g., acetoacetates), beta-diketones (e.g., 2,4-pentanedione), beta-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other beta-dicarbonyl compounds that can participate in the Michael addition reaction as "Michael donors.". These water-dispersable resins cure under standard ultraviolet (UV) cure conditions to give tack-free coatings without the addition of traditional photoinitiators. The present invention further relates to the use of these resins in coatings.
Abstract:
The present invention relates to radiation-curable overprint varnishes for printed substrates based on multifunctional, uncrosslinked, liquid Michael addition resins. The compositions are UV-curable with little or no photoinitiator present.
Abstract:
The introduction of nanostructures in a liquid provides a means for changing the physical and/or chemical properties of the liquid. Improvements in heat transfer, electrical properties, viscosity, and lubricity can be realized upon dispersion of nanotubes in liquids. Stable dispersions of nanostructures are described and surfactants/dispersants are identified which can disperse nanostructures in petroleum liquid medium. The appropriate dispersant is chosen for the selected nanostructure material and the oil based medium and the dispersant is dissolved into the liquid medium to form a solution. The nanostructure is added to the dispersant containing the solution with agitation, ultrasonication, and/or combinations thereof Nanostructures dispersed in a fluid form a nanofluid utilized as a shock absorber oil whereby the nanostructures serve to improve the viscosity index of the fluid or more particularly the shock absorber oil in the form of a lubricant additive.
Abstract:
The present invention relates generally to radiation-curable ink formulations, and particularly, but not by way of limitation, to a family of radiation-curable ink formulations specifically for flexographic and screen printing applications. The inventive ink formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with ß-keto esters (e.g., acetoacetates), ß-diketones (e.g., 2, 4-pentanedione), ß-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ß-dicarbonyl compounds that can participate in Michael addition reactions.
Abstract:
The invention detailed herein comprises a family of multifunctional acrylate oligomers which are useful as pigment grinding vehicles for use in radiation-curable coating formulations. The multifunctional acrylate resins are formed by the reaction of acrylate monomers and oligomers with ß-keto esters (e.g., acetoacetates), ß-diketones (e.g., 2, 4-pentanedione), ß-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ß-dicarbonyl compounds or Michael "donors" that can participate in the Michael addition reaction. These resin vehicles have a built-in chromophore that enables ink formulations made from their dispersions to cure under standard UV-cure conditions with significantly less photoinitiator than commercial formulations. The resins also exhibit excellent pigment wetting characteristics and can be designed to function as a single dispersion vehicle for different pigments and different ink applications such as screen, flexographic, and lithographic printing.

Abstract:
A blow tube for delivering particulate material from a container thereof to a mold to form a core has a unitary, elongate body formed of resiliently elastic material which enables the body to adjust and compensate for misalignment of the container and the mold. The blow tube body has a bore having a plurality of axially spaced sections so that when the particulate material is blown through the body by compressed gas, the density of the particulate material is increased and the velocity of the gas and particle stream is increased. The elasticity of the blow tube body enables the latter to expand in the event the particulate material clogs the blow tube, thereby enabling the clog to disaglomerate.
