Abstract: A method for separating protein from plant or algae material is disclosed. The method comprises mixing the protein-containing material with a solvent, preferably water; extracting the protein-containing material at pH>7; and acidifying the mixture, thereby precipitating protein and fiber together. In some embodiments of the invention, the separation additionally comprises decanting the mixture to recover a protein/fiber solid; adding water to the protein/fiber solid; adding a predetermined quantity of base to the protein/fiber/water system, thereby precipitating fiber; separating the fiber from the protein in a decanter; and drying the protein solution. In other embodiments, the protein/fiber solid is processed directly, e.g. by being passed to an extruder. The use of the fiber as a carrier for the protein makes the inventive method more efficient than methods known in the art; in particular, the inventive method does not require the use of a high-g clarifier centrifuge.

Abstract: A water-soluble insert for use in joining pipes, made of a material comprising a salt selected from the group consisting of KCl, Na Cl, and mixtures thereof; and MgO. Upon addition of a small amount of water to the material, the MgO reacts with hygroscopic impurities in the chloride salt to provide a material with superior properties. The insert is cast from the material, in general by being placed on a form and compressed. Also disclosed is the use of the insert in joining the ends of two pipes, especially pipes made from thermoplastic. The insert is placed in the matching pipe ends, which are then welded. After the join is complete, water is flowed through the pipe, dissolving the insert.

Abstract: A mixture suitable for use in forming a magnesium silico-phosphate cement is disclosed. The mixture comprises particles of MgO at least partially coated with an additive adapted to alter the setting time of said cement cast; a phosphate salt or acid chosen that will provide a binder product characterized by the empirical chemical formula MMgPO4.6H2O; and an aggregate phase chosen from the group containing (a) CaSiO3, (b) MgSiO3, (c) SiO2, (d) fly ash, (e) sea sand, and (f) any combination thereof. Coating the MgO particles provides better control of the alteration of the setting time and better physical properties of the set cement. Methods for making the mixture and for preparing a cement cast based on the mixture are also disclosed.

Abstract: A cement mix for preparation of a magnesium silico-phosphate cement (MSPC) with an altered hardening rate is provided. The cement mix comprises on the order of 1% of an [MF6]n? salt or acid. Upon addition of water, the mix produces a final set cement that has similar physical properties to those of a cement prepared from a mix lacking the additive, but with a significantly altered setting time. In some embodiments of the invention, the additive is provided in the form of a coating for the MgO component of the mix. In preferred embodiments, H2TiF6, Na2TiF6 and/or K2TiF6 are used as retarders, while K3AlF6 is used as an accelerant. Other embodiments use M?nMF6 compounds wherein M? is an alkali metal, an alkaline earth metal, or H, and M is chosen from inter alia Ti (n=2), Zr (n=2), P (n=1), Al (n=3), and Sb (n=1).

Abstract: A method is provided for advantageously altering the rate of hardening of a magnesium silico-phosphate cement (MSPC). Addition of on the order of 1% of an [MF6]n? salt or acid to an MSPC, obtained by adding the salt or acid either directly to the dry mix or to the water used to effect hydraulic hardening of the cement, significantly alters the hardening rate without adversely affecting the physical properties of the final set cement. In preferred embodiments, Na2TiF6 and/or K2TiF6 are used as retardants, while K3AlF6 is used as an accelerant. Other embodiments use M?n-MF6 compounds wherein M? is an alkali metal, an alkaline earth metal, or H, and M is chosen from inter alia Ti (n=2), Zr (n=2), Si (n=2), P (n=1), Al (n=3), and Sb (n=1).
