Abstract: A cylinder head is provided for a compressor, including at least one coolant-conducting region and at least two air-conducting regions. The at least one coolant-conducting region is arranged at least partially around the at least two air-conducting regions. The at least two air-conducting regions have at least one air-feeding duct for feeding the air to be compressed into the compressor and at least one air-discharging duct for outputting a compressed air which is compressed by the compressor. The at least one air discharging duct includes an open-pore, metallic cell structure.

Abstract: An arrangement for fixing a component inside of a wind turbine is disclosed. The arrangement has a portion of a tower and a direct fastener. The direct fastener has a first part and a second part and the portion of the tower is a portion of a wind turbine tower. The first part of the direct fastener is driven into the portion of the tower and is connected thereto by a combination of friction hold and bonding. The second part of the direct fastener protrudes from the portion of the tower and connects to a component.
