Abstract: The aim of the invention is to provide a solution for guiding the cutting of a piece of plasterboard, which can be rapidly implemented, and does not require any finishing step for refilling the surface of the piece of plasterboard. To this end, the invention relates to a guide element (200) for guiding the cutting of a piece of plasterboard, said guiding element having two longitudinal edges and two ends, for guiding a cutting blade, during operation, parallel to the guiding element, said guiding element also comprising, at least on one end, a rotatably mounted abutment (210) provided with means (211) for holding the abutment against the piece of plasterboard.

Abstract: The invention relates to a solution for rapidly grooving a piece of plasterboard, enabling the creation of a plane cutting edge and a precise cut-out of the layer(s) of paper or cardboard. To this end, according to the invention, the cutting is carried out in three main steps by means of a blade having a particular shape and sharpness: a step of grooving, a step of breaking the plasterboard, and a step of levelling the cutting edge. The invention therefore relates to a blade (300) for cutting a piece of plasterboard, characterised in that it comprises at least one grooving corner (301) having a plane face and a bevelled face.

Abstract: A controlled RF active duplexer comprises two distributed amplifiers and means for controlling them. Each distributed amplifier comprises an input line and an output line, the output line of the first distributed amplifier being common to the input line of the second distributed amplifier. An end of the input line of the first distributed amplifier forms the input port, an end of the output line of the second distributed amplifier forms the output port and an end of the line common to the two distributed amplifiers forms the input/output port. The distributed amplifiers are placed in the on state or in the off state in opposition to one another as a function of the ports to be made to communicate. The invention makes it possible to carry out the splitting of the RF signals within a compact space and isolation between input port and output port.
