Abstract: A centrifugal separator has a rotary drum that is adapted to receive a product that can be separated into a light phase, a heavy phase, and solid sediments, a first outlet for the light phase, a closing device that opens and closes a second outlet for the heavy phase. The closing device has an electromagnetic actuator having a ferromagnetic element whereon a closing plug is mounted. The electromagnetic actuator has an electromagnetic coil that creates a magnetic field so as to attract the ferromagnetic element. A spring is connected to the closing plug so as to urge the closing plug to a closed position. The closing plug, the ferromagnetic element and the spring are connected to the rotary drum.

Abstract: A plow apparatus has a share to cut soil into clods, a moldboard connected to the share to turn over the clods, a beam connecting the moldboard to a motor vehicle, a vibrator assembly connected to the moldboard so as to vibrate the moldboard, a force sensor connected to the beam so as to detect a plowing force, and a controller connected to the force sensor and the vibrator assembly so as to control a vibration of the vibrator assembly according to a force value detected by the force sensor.

Abstract: A plow has a share used to cut the soil, a moldboard connected to the share used to turn over the cods of soil cut by the share, a beam connecting the share-moldboard assembly to a motor vehicle, a vibrator assembly connected to the moldboard to put the share-moldboard assembly into vibration, a force sensor connected to the beam to detect the ploughing force on the beam, a controller connected to the force sensor and the vibrator assembly to control the vibration of the vibrator assembly according to the force value detected by the force sensor, the controller being set in such manner to acquire the force values from the force sensor, pursuing a minimum force through the control of the vibrator assembly.

Abstract: A centrifugal separator or decanter having a rotary drum wherein product is introduced in order to be separated at least in a light phase and a heavy phase, a first outlet of the light phase, a second outlet of the heavy phase, and a closing device adapted to close/open the second outlet of the heavy phase and/or a third outlet of solid sediments. The closing device has an electromagnetic actuator.

Abstract: A motor vehicle comprising an electric motor, at least one battery, and an electronic regulation unit connected to a potentiometer of the accelerator to regulate the power supply of the electric motor. The stator of the electric motor is rotatably mounted on two fixed supports joined to the frame of the vehicle, an axle shaft of a wheel is connected to the stator and the axle shaft of the other wheel is connected to the rotor. The vehicle additionally comprises a rotation reversing device to reverse the rotation of one of the two axle shafts of the wheels with respect to the rotation of the rotor or stator, respectively, an endothermic motor, an electric generator connected to the battery and a three way clutch to couple the endothermic motor to the generator and/or stator of the electric motor.
