Abstract: A rotary cage press provided internally with a deformable flexible membrane having the form of a half of the cage, this press being characterized in that the elements of recovering the liquid part of the matter include on the cage, at least one external racking device, and a connection unit through which opens out the outlet orifice of the racking device; and on the chassis, a liquid taking device including a telescopic tubular unit allowing a retracted position in which the telescopic unit presents no obstacle to the rotation of the cage and an extended position in which the telescopic unit is adapted, when the cage is in a predetermined pressing angular position, to come against the connection unit bearing in a seal-tight manner around the outlet orifice of the racking device.

Abstract: A method for dejuicing grapes uses a dejuicer comprises a closed tank provided with a dejuicer grid and an inflatable membrane in the tank which is pressurized to force juice out of the harvested grapes through the grid. A conveyor in the tank remove the dejuicer grapes from the tank. Harvested grapes are placed in said tank and the juice is allowed to flow naturally. The inflatable membrane mounted in the tank is then pressurized to force out further juice through the grid and the juice is collected from the tank. The membrane is then depressurized and the tank is emptied by actuating the conveyor.

Abstract: This invention relates to a composite material for construction purposes, constituted by a mixture based on cement, pozzuolanas and glass fibers, wherein the mixture comprises:on the one hand, hydrated pozzuolanas obtained from kaolinic compounds,and on the other hand, non-metallic, inorganic glass fibers sensitive to alkalis.The invention also relates to processes for making this product adapted for the manufacture of bearing or insulating panels for buildings.

Abstract: The invention provides a helical screw press for processing grape crop in which a filter tube diverges from a predetermined section of its length in downstream direction such that the divergence enables the grapes to be released and prevents formation of an impermeable crust in the filtering tube thereby permitting total pressing and increased flow rate.
