Abstract: Embodiments of the invention comprise a method of making a construction board (also known as wallboard) and a device for making same. The resulting construction board is formed by mixing of at least magnesium oxide, magnesium chloride, and a binding agent into a slurry, adding particulized solid material while funneling the slurry, and extruding the slurry comprising the particulized solid material.

Abstract: A cement retarder composition, method, kit and system are herein disclosed. Seeds are added to cement to delay the setting of cement. Cement retarders are added to cement to delay the setting of the cement until it is pumped to the desired position.

Abstract: Wheat starch of the present invention is obtained from endosperm of a seed of wheat which is modified to lack starch granule protein-1 (SGP-1). The wheat starch has an apparent amylose content of about 35% or more. Wheat flour of the present invention is obtained from endosperm of a seed of wheat which is modified to lack SGP-1. Wheat of the present invention is modified to lack SGP-1. The wheat flour and the wheat comprise wheat starch which has an apparent amylose content of about 35% or more.

Abstract: Wheat gluten protein-based biodegradable or edible films are produced using aqueous, essentially alcohol-free casting dispersions containing modified wheat protein and a plasticizer. The modified wheat protein is prepared by treating purified naturally occurring wheat protein with a reducing agent (e.g., sodium metabisulfite) in order to reduce the average molecular weight of the wheat protein and to cleave disulfide bonds therein. Such modified wheat gluten protein lowers the viscosity and allows increased solid contents in the casting dispersions, allowing fabrication of improved films.

Abstract: Gluten protein-based biodegradable or edible films are produced using aqueous, essentially alcohol-free casting dispersions containing modified protein (preferably wheat gluten protein) and a plasticizer. The modified protein is prepared by treating purified naturally occurring wheat protein with a reducing agent (e.g., sodium metabisulfite) in order to reduce the average molecular weight of the wheat protein and to cleave disulfide bonds therein. Such modified wheat gluten protein lowers the viscosity and allows increased solid contents in the casting dispersions, allowing fabrication of improved films using continuous casting techniques and without use of organic solvents.

Abstract: Compound intended to be added to concrete mass for entraining air in the concrete, thus increasing frost-resistance of the hardened concrete. The compound consists of: cereal storage proteins from wheat, triticale, barley or rye; a reducing agent preferably in the form of FeSO.sub.4 in an amount adapted to the original properties of the cereal storage proteins to entrain air in the concrete mass during its mixing; an inert substance, preferably Portland cement or mineral powder in an amount adapted to the original capacity of the cereal storage proteins to entrain air in the concrete. By means of the reducing agent and the inert substance the compound is normalized to its effect to entrain air in the concrete irrespective of said original properties and capacity of the cereal storage proteins to entrain air in the concrete.
