A device and a method for manufacturing a rotor blade for a wind energy installation, wherein the rotor blade includes at least two rotor blade shells which are bonded together, includes a holding device arranged to hold a rotor blade shell such that at least one bonding surface on the rotor blade shell and/or on a web attached to the rotor blade shell is exposed. The bonding surface of the rotor blade shell can be bonded to a further rotor blade shell. The device further includes a robot arm arranged to apply adhesive to the at least one bonding surface, a carriage on which the robot arm is mounted, and a guide device mounted on the holding device. The carriage is mounted on the guide device so as to be movable. The guide device is arranged to guide the carriage and the robot arm along the holding device, in particular along the bonding surface.

An impulse turbine of a turbine device includes a cylindrical body having an axial hole, and a blade unit arranged to surround the periphery of the body. The blade unit includes a cylindrical base arranged to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along the periphery of the base. Each of the unit blades includes an outlet that discharges fluid, injected onto the unit blade, in a direction different from the fluid spray direction, but does not discharge the fluid toward the other unit blades.

A rotor blade having a rotor blade trailing edge which extends between a rotor blade root and a rotor blade tip over a rotor blade length, and having a profile depth which is established between the rotor blade trailing edge and a rotor blade leading edge. For the purpose of improving efficiency, at least one profile element having a continuous profile section, for the purpose of changing the profile depth of the rotor blade, is able to be attached at or in the region of the rotor blade trailing edge, wherein the extension of the profile section beyond the rotor blade trailing edge is determined in a manner dependent on a standardized load-dependent dimensioning of the profile depth of the rotor blade and a load level which is established at an erection location of the wind turbine.

Disclosed are an impulse turbine and a turbine device. The disclosed impulse turbine includes a cylindrical body having an axial hole, and a blade unit arranged to surround the periphery of the body. The blade unit includes a cylindrical base arranged to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along the periphery of the base. Each of the unit blades includes an outlet that discharges fluid, injected onto the unit blade, in a direction different from the fluid spray direction, but does not discharge the fluid toward the other unit blades.

The invention relates to an inlet structure of a reservoir pot, comprising a base plate, which can be arranged in an operating medium tank with the formation of a receiving volume below the base plate, and a plurality of first elements which extend from the base plate, wherein the first elements are at least partially spaced apart from one another, and operating medium can flow between the first elements into the receiving volume and can flow out of the receiving volume, wherein the first elements present a greater flow resistance in the outflow direction than in the inflow direction.

A seal apparatus for a casing of a turbomachine. The seal apparatus may include an annular body having first and second annular body portions and an appendage. The second annular body portion may extend axially from the first annular body portion and may have an outer annular surface radially offset from an outer annular surface of the first annular body portion. The appendage may extend axially from the first annular body portion and may have an outer annular surface and an inner annular surface. The inner annular surface of the appendage and the outer annular surface of the second annular body portion may define an annular cavity therebetween, and at least a portion of the appendage may be configured to be displaced radially outward in order to maintain contact with first and second inner cylindrical surfaces of the casing during radial expansion of the casing.

A pneumatic motor for pneumatic tools includes a cylinder provided therein with a vane wheel. A rotating shaft inserted in the vane wheel is provided with a withstanding member and a tightening member, which can push the withstanding member to move toward the vane wheel and tighten the vane wheel with the rotating shaft for avoiding gap between the vane wheel and the rotating shaft. Thus, when outside driving air pushes the vane wheel to rotate, the vane wheel can synchronously drive the rotating shaft to rotate immediately and truly. By so designing, this invention can solve the problems of the conventional pneumatic motor that is likely to cause starting delay, untrue in power transmission and easy to wear.
