Abstract: A cross-cutting circular saw device comprising: a frame (1); a guide (10) carried by the frame (1) and adapted to span an object (5) to be cross-cut by sawing; a carriage (3) mounted for reciprocal movement along the guide (10); at least one circular saw blade (4A, 4B) carried by the carriage (3); a motor (11) for moving the carriage (3) and rotating said at least one saw blade (4A, 4B), said motor (11) being fixed to the frame (1); a first transmission (2) arranged between the motor (11) and the carriage (3) for transforming an output of the motor to a reciprocating movement of the carriage (3) along the guide (10); and a second transmission (8, 9) arranged between the carriage (3) and the at least one saw blade (4A, 4B) for transforming the reciprocating movement of the carriage (3) to a rotation of said at least one saw blade (4A, 4B).

Abstract: The invention relates to an oscillating circuit for the elimination or reduction of static electricity which is generated in material (1) of machines for treatment or handling or in electrical apparatuses, the oscillating circuit consisting of an electrical circuit, which together with a discharger (2) is included in a unit for discharging static electricity. The oscillating circuit includes a feedback looped inverter (4) consisting of one inverter unit or more inverter units connected in parallel or a feed-back looped series of inverters connected in series, each inverter consisting of either one inverter or a plurality of inverter units connected in parallel, each inverter including one or more transistors. The amplitude of the voltage of the potential oscillation which is transmitted to the discharging means (2), amounts to between 0.1 and 100 V and preferably to between 2 and 15 V.
