In wired communication for transmitting communication signals controlling the operation of an electric energy generating and converting system (101) of electric devices (111, 112) and transmitting between a processor (155) comprising ROM and RAM memory, a controller (150) of a microinverter of the electric energy generating and converting system (101) of the electrical devices that generate direct current electric energy, and a communication controller (180), branches of electric circuits being a communication transmitting branch (275) of the communication controller (180) and a control receiving branch (260) of the microinverter controller, which together with an electric neutral wire (N) and a bidirectional communication electric wire (CTL) form a communication line transmitting a communication signal TX from a transmitting pin (MTX) of the communication microcontroller to a receiving pin (RX) of the processor (155) of the controller (150) of the microinverter (120), and a control transmitting branch (360) of the controller (150) and a communication receiving branch (285) of the communication controller, which together with the electric neutral wire (N) and the bidirectional communication electric wire (CTL) form a communication line transmitting a communication signal TX from a transmitting pin (TX) of the microinverter processor to a receiving pin (MRX) of the communication controller (180).

In a system for removing impurities, including fats, greases and petroleum substances, from metal elements, having a set of devices formed in the form of a production line (2) and including a dosage device (20) for transporting impure metal elements (15), and a shredding device (30), in the production line (2) for removing fats and/or greases and/or petroleum substances and other impurities from impure metal elements (15), downstream the shredding device (30), there is a mixing device (60) with a tank (61) moving at least rotationally in relation to its own longitudinal axis (66), preceded in the production line (2) by a dosage-powdering device (20) transporting a degreasing material (45), and a dosage-transporting device (50) transporting a wiping material (55). Furthermore, in the production line for removing fats, greases and petroleum substances from metal elements, downstream the mixing device (60), there is a separating device for separating purified metal elements (75) from a mixture (77) containing degreasing material and wiping material with fats and/or greases and/or petroleum substances.

In a system (1, 101, 201) for spraying hot-melt adhesive onto glued surfaces comprising a melter (61) to heat hot-melt adhesive, an air compressor (60), a power and control system (63) and a gun (10). The gun (10) is connected to the melter (61) by a pipe (53) with screw connectors (54, 55), through which a hot-melt adhesive being heated flows, and the air compressor (60) by an air pipe (56) with screw connectors (57, 58) through which a pressurized compressed air flows. The gun (10) has a nozzle (20) with a hot-melt adhesive outlet or orifice (21) and a compressed air outlet (23). The pipe (53) through which flows the hot-melt adhesive having a viscosity between 2500 mPa*s and 7000 mPa*s and a temperature between 120°C and 200°C, and a density between 0,8 kg/dcm³ and 1,4 kg/dcm³, and the air pipe (56) are fitted in an insulating layer of a hose (50), and whereas the throughput of the pipe (53) through which the hot-melt adhesive being heated flows is between 0,5 kg/h and 1,5 kg/h, while the air pipe (56) has a throughput between 0,1 m³/min and 0,6 m³/min.
