The present invention relates to a composition for a single-paste type hydraulic endodontic filling material comprising dimethyl sulfoxide (DMSO). According to one aspect of the invention, there is provided a single-paste type hydraulic endodontic filling composition, comprising a calcium silicate component and DMSO.

This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

The present invention relates to a composition of an intracanal medication agent for medicating root canals for a predetermined period of time. According to one aspect of the invention, there is provided an intracanal medication composition based on a calcium hydroxide component, comprising: calcium hydroxide or a calcium hydroxide producing component as a powder component; and at least one of diethyl sulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP) and diethylene glycol monoethyl ether (DEGEE) as a liquid component.

A metal object produced by a three-dimensional (3D) metal object manufacturing apparatus is subjected to a high temperature heat treatment to improve bonding of the object layers, especially in the vertical or Z-axis direction. A supporting structure is formed around the metal object to retain the shape and features of the object during the high temperature heat treatment. The supporting structure is formed in a manner that is sufficient to retain the shape of the metal object during the heat treatment but is easily removed once the heat treatment is finished.

Compositions and methods are provided for the recovery of minerals from mineral suspension, such as lime generated in Kraft pulping processes. More particularly, the composition comprises polyalkoxylate co-polymers, alkyleneamine alkoxylates, and optionally anionic surfactants, that when added to mineral dewatering process, aids in the recovery of the mineral,

Cement and concrete compositions are produced via metal hydroxides and metal oxides isolated from aqueous sources such as seawater or wastewater. Aqueous solutions are electrolyzed to produce an alkaline component stream having an elevated pH, which when mixed with mineralized seawater causes metal ions dissolved therein to precipitate out in the form of metal hydroxides such as Mg(OH).sub.2 and Ca(OH).sub.2. These metal hydroxide products are then utilized as feedstocks for production of cement and concrete structural elements, or are converted to metal oxides suitable for the same purpose. The hydroxide products are then subjected to pressure and prolonged exposure to carbon dioxide to accelerate carbonation of the hydrated product. The resulting carbonates exhibit sufficient compressive strength for use in making structural components for construction, while reducing or eliminating the carbon footprint associated with traditional methods of cement and concrete manufacturing. Excess demineralized alkaline component can be recycled for additional electrolysis, or returned to a neutral pH for use in water desalination processes or even returned to the environment.

The invention relates to a process for modifying polymer particles of an aqueous polymer dispersion in which positively or negatively charged polymer particles are provided with an inorganic salt shell. The inorganic shell leads to an improved drying ability and storage stability of the latex and improves the storage stability of the resulting polymer powder. The obtained polymer powder exhibits an improved viscosity and faster skin-forming time in the final application and is therefore particularly useful in a building material composition.
