    摘要: An air heating system comprises a duct housing an air-cooled internal combustion engine which drives a fan to cause air to be drawn in through an inlet mouth of the duct and blown through the duct to a utilizer. The exhaust gases from the engine are fed as heating fluid to a heat exchanger through which they pass in a helical path concentric with the axis of the duct. Pre-heating of the air drawn into the duct can be achieved by providing a second heat exchanger through which air must flow before entering the duct inlet. The heating fluid for the second heat exchanger comprises a mixture of the used air from the utilizer and the exhaust gases leaving the main heat exchanger in the duct.

    摘要: An edge-trimmer comprises a holdable support arm (2), a cutting head (3) rotatable about a rotation axis thereof (C) and positioned in proximity of an end (2b) of the support arm (2); a motor for moving the cutting head (3) by means of a transmission organ (5), an orientation device (6) of the cutting head (3) in the space connected to the support arm (2) and rotatable about a first rotation axis (A). The orientation device (6) exhibits a rotatable junction (7) which enables the cutting head (3) to further rotate about a second rotation axis (B) which is inclined with respect to the first rotation axis (A).
