Abstract: Method for preparing adhesive compositions subjecting a mixture of block polymer and other adhesive constituents e.g., resin(s) and oil(s) to shearing and smearing in an emulsifier disperser.

Abstract: Method for preparing adhesive compositions by dissolution of the block polymer component(s) thereof in a hot melt of the other adhesive constituents e.g., resin(s) and oil(s).

Abstract: A process for the purification of soil contaminated with organic material is provided. The preferred process generally involves superposed attrition and classification processes, which lead to removal and concentration of highly contaminated fractions. The process may also include a step of flotation whereby hydrophobic materials in the soil are released to an interface with air bubbles, and are floated to the top of a flotation cell. In preferred processes according to the present invention, soil to be treated is extracted from a contaminated site, and is broken into relatively small particles. These particles are preferably treated in attrition and classification steps, to remove fine, slow settling contaminated materials such as wood and fine soil materials. The resulting isolated coarser materials are then treated by flotation for a final polishing step.

Abstract: An arrangement for operation to reduce organic contaminant concentration in water passing therethrough as provided. The arrangement includes at least one reactor comprising a plurality of treatment chambers oriented in series, each chamber including an upstream downcomer portion and a downstream column portion separated by a wall member. Fluid flow is provided between a downcomer portion and the column portion. Means are provided such that water can flow through any associated chamber by introduction into an upper portion of the downcomer portion of the chamber, with passage downwardly to a feed space and a bottom portion of the column portion of the chamber and upwardly through the column portion. The water then flows outwardly from the chamber, into a next downstream chamber if one is provided.

Abstract: Substantially pure honey, molasses, or mixtures thereof can be dried using extrusion or thin film drying. An improved cooling technique can be used with the thin film drying method by applying the hot dried molasses and honey to a cold, rotating cylinder, and then collecting the cooled product from the cylinder.

Abstract: The present invention deals with an improved process for recovering protein.

Abstract: Normally tacky and pressure-sensitive adhesive tapes, labels, etc. which, when adhered to dry fibrous webs, remain firmly attached when the web and adhesive are thereafter exposed to moist conditions. These performance characteristics, which are not found when conventional pressure-sensitive adhesives are used, result from employing acrylate-based copolymer adhesives made from specific monomers and having inherent viscosities related to the monomers employed.
