A vacuum pump capable of suppressing the solidification of gas in a normal operation of a pump is provided. Provided is a vacuum pump including a casing that has an inlet port for sucking gas from outside and an outlet port for exhausting the gas to the outside; a turbo-molecular-pump mechanism that is disposed in the casing and includes rotor blades and stator blades alternately arranged in multiple stages in an axial direction; a thread-groove-pump mechanism that is disposed in the casing and is connectedly disposed on an exhaust side of the turbo-molecular-pump mechanism; first temperature regulating means that is configured to regulate cooling of the turbo-molecular-pump mechanism; and second temperature regulating means that is configured to regulate heating of the thread-groove-pump mechanism.

A hollow structural element of a wind energy plant, in particular an offshore wind energy plant which includes a hollow structural element, and a cable arrangement extending along the hollow structural element. A shading element is arranged on the hollow structural element at a distance from the cable arrangement.

A wind turbine is presented. The wind turbine includes a rotor having a plurality of blades. The wind turbine further includes a shaft coupled to the rotor. Moreover, the wind turbine includes a superconducting generator coupled to the rotor via the shaft. The superconducting generator includes an armature configured to be rotated via the shaft. The superconducting generator further includes a stationary field disposed concentric to and radially outward from the armature.

An actuator includes a strand of shape memory material having a length that is variable between a first length corresponding to an undeformed state and a second length corresponding to a state of lengthwise deformation. The strand is arranged to return to the undeformed state when it is heated to a predetermined temperature. The strand includes a fixed end and a mobile end arranged to move between a first and a second position when the variable length of the SMM strand changes. The actuator further includes a heating wire coiled around the strand for heating the strand, the coiled heating wire forming a circular helix, the uniform slope of which is selected so as to avoid any substantial change of the arc length of the circular helix caused by the strand changing its length.

A rotor blade mold for producing a rotor blade, a method for producing a rotor blade mold, the use of a rotor blade mold, a spray device for producing an insulation layer, and an adhesive product. A rotor blade mold for producing a rotor blade or a part of a rotor blade, in particular of a wind turbine, comprising a mold insert, having a mold side which forms a cavity for molding a rotor blade or a part of a rotor blade, and a structured side facing away from the mold side, an insulation layer arranged on the structured side, and having an adhesive, and a plurality of pouring elements made of an insulation material.

A hollow structural element of a wind energy plant, in particular an offshore wind energy plant which includes a hollow structural element, and a cable arrangement extending along the hollow structural element.
