Abstract: A valve usable to repeatedly open and close a filling-emptying channel associated with a a beverage container includes a valve body (1). The valve body has a central ring (2) supported by arms (7). The ring includes a hole (4). The valve has a deformable valve plate (5) that includes an outer circumferential beveled edge (10). The valve plate further includes a central conical part (6) configured to engage in the hole. When in blocking relation of the channel, the conical part is engaged in the hole and the valve plate has a convex cup shape. Pulling outwardly on the valve body, changes the convexity of the valve plate and enables it to be disengaged from the valve body.

Abstract: The invention solves the problem of obtainment of binding agent for mass of shape constriction elements, consisting of the fact, that preferably calcium sulfate, preferably calcium oxide, preferably zinc oxide, are initially mixed in mechanical mixer, and after thorough mixing, the obtained dry mass shall be subjected to the effects of ultrasonic stationary wave. The binding agent for mass for production of shaped construction elements, in accordance with the invention, consists of 65-86% of weight, preferably of calcium sulfate, 15-35% of weight, preferably of calcium oxide and 0.1-0.7% of weight, preferably of zinc oxide.

Abstract: This invention concerns a system of construction elements for the dry construction of a structure by way of shaped protrusions for mutual connection during assembly. It consists of construction element modules for raising walls, the ceiling and roof, and that the module consists of two elements with adjacent sides connected by a third element, creating a self-tightening connection, and the shaped protrusions of construction elements have two lateral contact surfaces, guiding (1) and self-tightening (2), inclined at specific angles ? and ?, and these angles are determined, respectively, between the perpendicular to the upper or lower protrusion surface and the guiding or self-tightening surface. The invention also includes applications of the specified system for raising compact and low structures, as well as for completing walls in buildings with skeletal constructions, and also as a block system for raising miniature constructions.

Abstract: A method is provided that solves the problem of the manner of obtainment of mass for production of shaped construction elements. The manner consists of the fact, that in the mechanical mixer a ceramic granulate is placed, preferably in the form of perlite and is soaked, preferably with water until complete soaking of the granulate and is mixed with the binding agent until obtainment of the situation, where each loose grain (1) of the granulate is coated with a layer of moist binding agent, creating a coating (2) around the grain. Priorly prepared moulds are filled with the obtained mass. The mass for production of shaped construction elements consists of 15-25% of bond weight, preferably in the form of perlite, 35-45% of binding agent weight, preferably in the form of plaster with improved resistance parameters and 35-45% of water weight.
