Abstract: A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and arc connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and arc electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, arc in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.

Abstract: A cable/lead insertion unit for the insertion and passing-through of at least one lead into and through a wall opening of a housing wall. An insertion sleeve is used for insertion into the wall opening and a bearing flange at least in places protrudes therefrom radially outwards. Furthermore, a clamp part, in particular screwable onto the insertion sleeve in the direction of the bearing flange, is used, as well as a fastening portion of the insertion sleeve situated opposite the clamp part. The fastening portion on its outside has a partially circumferential thread turn, by which a clamping element can be brought into engagement for pressing the bearing flange onto a rim of the wall opening.

Abstract: A forcing-off device of an, in particular, explosion-proof or flameproof container for electronic devices, the container including at least one base body having an opening surrounded by an opening edge and a cover part that can be placed onto or inserted into the opening edge. A forcing-off shoulder is formed on the base body or cover part at least in a section in circumferential direction of the container. The forcing-off shoulder is part of a shoulder running around the opening edge, and at least one forcing-off part is rotatably mounted in a lateral recess of the cover part or on the base body in an eccentric fashion between a forcing-off position and a passive position. The forcing-off part is an eccentric disc and in the forcing-off position is in abutment with the forcing-off shoulder for the gap-forming spacing of cover part and base body.

Abstract: A wind turbine comprising a drive shaft; at least one vane connected to the drive shaft; and a torque converter attached to the vane, the torque converter comprising an airfoil, the torque converter being adapted to capture air for use in aiding the vane to rotate. Certain embodiments include the vane comprising a first surface and a second surface positioned opposite to the first surface, the first surface comprising a plurality of wind disrupters. Certain embodiments include a plurality of vanes rotatably connected to the drive shaft, the plurality of vanes comprising a plurality of strakes adapted to capture air and direct air to the drive shaft. Yet certain embodiments include a first air scoop connected to the vane, the first air scoop comprising a first air scoop portion at an angle relative to the vane.

Abstract: A vertical axis omni-wind turbine having a wind sail centrally mounted to a turbine drive shaft, the wind sail consisting of three generally identical vanes paced 120 degrees apart. The vanes each have a generally concave surface for capturing impinging wind thrust with an opposite generally convex surface to provide minimal wind resistance. The resulting disparate wind resistance causes a stronger reaction on the concave side of a vane which in turn provides rotation about the vertical oriented drive shaft. The turbine has omni-wind characteristics in that regardless of the wind direction an adequate portion of the concave surface of a rotor blade will always be exposed to impinging wind. The subsequent drive shaft rotation is transmitted to an electrical turbine.
