Abstract: The invention relates to a composite stainless steel and wood barrel comprising a metal body, to which a gasket made of appropriate liquid-resistant material is attached. The wooden slats are inserted into a metal frame and tightened in a vertical sense with screws. The metal frame filled with slats, is attached to the metal body with screws. An arbitrary number of various connecting elements for attaching the fermentor, the inert gas system, the pump and for wine-sampling are added to the metal body. The structure provides for the barrel to be mounted on metal legs which, apart from providing stable positioning of the barrel, enables the barrels to be arranged in a row 10 cm apart from each other and is also used for raising the body of the barrel 40 cm from the ground, thus facilitating decantation.

Abstract: In a capacitive keyboard using a polarized dielectric commonly called an electret, the keys are organized according to a matrix by rows and columns, the signals generated on the column conductors being of opposite polarity with respect to those generated on the row conductors. The movable armatures of the variable capacitors of the keys also act as bridging elements to allow the crossing of the row and column conductors and as snap elements.
