Abstract: Apparatus and methods for circulating air. The apparatus may include a ceiling fan and may include a light fixture. A motor assembly may drive the fan about a rotational axis. Blades of the fan may be fixed to an outer ring of a blade bracket. Blades may extend away from the outer ring. The blade bracket may also include a translucent blade support to which the outer ring may be fixed. The translucent blade support may be disc shaped. A blade holder adapter may fix an inner portion of the translucent blade support to the ceiling fan. The fan may be configured such that a portion of the translucent blade support may provide a view unobscured by the translucent blade support so that there may be at least partial visibility of a visible element, such as a structure, above the translucent blade support from below the apparatus.

Abstract: A component of a rotary machine extends to an axial direction and a radial direction vertical thereto, and has an inner channel, extending from a first end of a core of a center of the component and to a second end at a radial limiting surface of the component and which is at least partially closed. A blank includes the core of the component and is limited by an outer surface in the radial direction. The blank is subtractively processed in a first subtractive process step, such that an outer contour is elaborated in the area of the outer surface, which extends in the radial direction, and a part of the channel is manufactured, which radially extends in the blank to the first end. The channel is formed by a build-up process on the blank.

Abstract: The disclosure concerns a fan wheel, including a base body with a rotational axis, and a swing part. The base body is made of a first material and the swing part is made of a second material. The density of the second material and the density of the first material are different. The swing part has a surface. The swing part is at least partially surrounded by the base body, so that the base body covers at least 80%, in particular at least 90%, preferably at least 95% of the surface of the swing part. The first material has a first thermal expansion coefficient, and the second material has a second thermal expansion coefficient. The second thermal expansion coefficient amounts to 70% to 110%, in particular 80% to 100%, preferably 85% to 95% of the first thermal expansion coefficient, and/or the swing part is substantially annular and runs fully closed around the rotational axis.
