Abstract: Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.

Abstract: A single dose dispensing package (100) having a backing (102) for maintaining the package in a substantially flat orientation is disclosed.

Abstract: The apparatuses, compositions and methods described herein generally relate to a new application for and formulation of composite-polymer composition. This composition is a nanocomposite, comprising a polymer and a clay, preferably a recycled polymer and a nanoclay. The nanocomposite composition has improved performance characteristics, such as lower creep values and lower coefficients of linear thermal expansion, and can reduce the dependency of plastic product manufacturing on virgin (unrecycled) polymers. Moreover, the nanocomposite is formed into geosynthetic materials, e.g., geomembranes, and storm water retention/detention systems.

Abstract: Reactive gabion cage or grid structures, and their methods of manufacture, for controlling contaminants in soil, sediment or water that allow the passage of essentially non-contaminated water therethrough. The articles and methods described herein utilize gabions cages or grids, which are box shaped cages or grids (see FIG. 2) made of either steel wire mesh or plastic. In one embodiment, reactive geotextile mats are disposed on a top major surface of a gabion cage or grid. In other embodiments, the cages or grids surround a geocomposite containing reactive material. The gabion cage or grid structures can be constructed in-situ (at the site of deployment) or remotely (on land or barge) and set in place. They are typically placed side-by-side and, in a preferred embodiment, are configured to cover a target sediment area, underwater. The gabion cages or grids may be filled with clean sediment, silt, sand and/or concrete block or rock to hold the reactive geocomposite in place and for armoring.

Abstract: A nanocomposite is made from melt-mixing of polyethylene with organoclay in the presence of a maleated polypropylene. Unexpectedly, the maleated polypropylene and polyethylene are sufficiently compatible to permit excellent dispersion of the organoclay in the nanocomposite. Because maleated polypropylene is compliant with U.S. Food and Drug Administration regulations, though maleated polyethylene is not, one can use nanocomposites of the present invention for articles to be in contact with human food.
