Abstract: The invention relates to a cylinder head (1) of an internal combustion engine with a camshaft bearing mechanism (2) situated thereon in which a hollow camshaft (3) is rotatably mounted, forming an outlet for discharging blow-by gases laden with oil droplets out of the crankcase and is designed as an oil droplet separator for separating the oil content out of these gases. The camshaft (3) passes through a valve space (11). A rocker cover (13) or a multichannel device (27) is connected axially to at least one end of the camshaft (3), forming an axial gap (9), each having a channel (10) connected coaxially to the hollow space (5) of the camshaft (3) so that blow-by gases from which the oil has been removed can be discharged from the camshaft (3), and each being designed so that they either form an oil collecting space (12) that is sealed with respect to the valve space (11) or they introduce oil that has been separated into such an oil collecting space (12).

Abstract: Wind-driven power plant comprising a rotor with any desired number of blades and rotating during operation in an at least approximately vertical plane, the individual blades of the rotor being attached by means of articulations to a hub, which hub is fastened to the rotor shaft, the hub being mounted in a head of the plant which is carried by a tower at a height above the ground which is greater than the length of the rotor blades. The rotor is mounted in a head part, the latter swinging into a vertical position when the plant is at standstill; the rotor blades are swung around their articulations when the plant is at standstill up to a position which is at least approximately vertical; and the ends of the rotor blades are kinematically coupled for joint swinging motion with the swingable head part.
