Abstract: A blower (1) with a blower housing (2), a blower wheel (4) positioned so as to rotate inside a blower housing (2), an electric motor (6) for the rotational drive of the blower wheel (4), as well as with a saucer-shaped attachment housing (8) positioned externally on the blower housing (2). The attachment housing (8) contains motor-control electronics (10) and exhibits in its connection area facing the blower housing (2) a metallic cover element (14) covering the motor control electronics (10) and protects against an electromagnetic radiation from the electric motor (6).

Abstract: The present invention relates to a wall ring for receiving in particular an axial fan, comprising an annular body with a flow inlet opening and a flow outlet opening and a central longitudinal axis X-X as well as an annular wall extending between both openings. The annular wall has a cavity which is enclosed by an outer wall and an inner wall, in which an electrical heating element may be secured at least over a partial area of the periphery of the annular wall. The annular body consists of at least two partial bodies which are formed by a division of the annular body in a separating plane that extends perpendicular to its longitudinal axis and are detachably connected to one another.

Abstract: The present invention relates to a support element (2) for holding a fan (1), in particular an axial fan, comprising a wall ring (4) for receiving the fan (1). The wall ring (4) has on its outer periphery a hinge (20) consisting of a first hinge part (22) that is connected to the wall ring (4) and a second hinge part (24) that can be pivoted about a hinge axis (X) relative to the first hinge part (22). The invention further relates to a fan (1) comprising such a support element (2).

Abstract: Flat illuminating display device with light emitting means to illuminate a film for display of an image applied to a display area, wherein the light emitting means are embodied as at least one light coupling unit arranged laterally at a translucent film thus forming a light duct, wherein the light such fed into the adjacent edge area into the film is reflected by a reflective layer, which is applied on at least one side, to homogeneously spread within the film, wherein a reflection screen to obtain a light emission is provided opposite of the display area to create said display area.

Abstract: A diagonal fan has a diagonal fan impeller (1) which is fastened to a rotor (2) of an external rotor motor (3) and which is arranged between a front plate (5), which has an in particular central inflow opening (6), and a motor bracket (4). The motor bracket (4) is connected to the front plate (5) via a plurality of peripherally arranged spacers (21). Here, the front plate (5) and the motor bracket (4) are formed as plastic or metal injection molded parts. The spacers (21) are formed, as plastic or metal injection parts, in one piece with the front plate (5) or with the motor bracket (4).

Abstract: The invention is related to diagnostic methods for detecting transmissible spongiform encephalopathies (TSEs) such as BSE and scrapie and related disease in humans. The invention provides use of guanidine thiocyanate (gdnSCN), or a functional equivalent thereof, for treating at least one sample derived from a mammal, including humans, for reducing the risk of scoring a false-positive test result in testing the sample for the presence or absence of aberrant prion protein.
