An attachment for monitoring a nut of a screw connection for crack formation, deformation, and/or breakage includes a socket portion which is attached to the outer circumference of the nut and has a conductor which is interrupted in the case of a deformation, crack, or breakage of the nut. The conductor is embedded in at least one material. The attachment is produced by injection molding with the conductor embedded within the socket portion. The monitoring attachment is particularly useful for operating a shutoff device for a wind generator in the event of failure of a nut which secures a turbine blade to the generator hub.

Nut integrity monitoring device and method

A current transformer arrangement, and method, include a current sensor for producing a sensor output voltage that is proportional to the input current flowing in a conductor; a first processing branch including a voltage calculating device for calculating the effective voltage value of the sensor output voltage; a second processing branch including a polarity detecting device having an input terminal connected with the current sensor output terminal to produce a polarity signal having one polarity when the conductor input current is either an alternating current, a hybrid current, or a direct current flowing in one direction, and the opposite polarity when the conductor input current is a direct current flowing in the opposite direction; and a multiplier device for modifying the effective voltage value to produce a signed effective voltage having a polarity corresponding with the polarity of the polarity signal. A modifying circuit modifies the signed effective voltage.

A lighting arrangement for illuminating a passage, such as a wind tower or tunnel, includes at least one lighting unit having a generally rectangular base with bottom, side and end walls cooperating to define an open-topped chamber, a pair of light energy sources arranged partially in the housing chamber for directing light beams toward opposite ends of the housing, respectively, and a cover member formed of light-transmitting material, which cover member is connected with the base to extend over the light energy sources and to close the housing chamber. The cover member includes a concave dome portion containing a cavity within which the light sources are mounted. Opposite areas of the cover dome portion define collimating devices for concentrating the light beams in opposite directions longitudinally of the passage that is to be illuminated. A plurality of lighting units are longitudinally-arranged in the passage, and are electrically connected in series.

A first adapter arrangement includes a housing having a sealing end supporting the housing in a vertical wall opening of a casing containing an electronics device, and a connecting end extending externally of the casing for connection with the housing of a companion adapter arrangement. A pair of resilient generally-annular longitudinally-spaced seal members are mounted concentrically about the adapter housing sealing portion for sealing the space between the adapter housing outer surface and the adjacent surface of the casing wall opening. An electrical connector mounted in a through passage contained in the adapter housing includes a conductor contact end connected with the conductors of the electrical device, and a connector contact end adapted for connection with the corresponding contacts of a companion second adapter arrangement. A fastening device serves to connect together the adjacent ends of the adapter housings of the first and second arrangements.

Adapter arrangement

An electrical connector for connecting the bare end of a horizontal conductor with a horizontal printed circuit board, including a sectional housing having a base member seated on the printed circuit board. The base member contains an open-topped chamber and includes a vertical front wall the upper edge of which contains a vertical slot communicating with the chamber. A cover member is normally seated on the base member to close the chamber and the upper end of the slot. A lower electrically conductive cage member is arranged in the bottom of the chamber for electrical connection with the printed circuit board. The cover member is removable from the base member to open the tops of the chamber and the slot, thereby to permit the horizontal conductor bare end to be displaced laterally vertically downwardly into the slot and housing chamber toward electrical engagement with the lower cage member.

A assembly support () of a front end of a motor vehicle is proposed, having at least one cooling module () which is detachably fixed to the assembly support () by means of at least two connecting points (). The assembly support () is characterized in that one of the connecting points () is embodied as a pivot bearing (), and in that the other of the connecting points () is embodied as a clip connection (). In addition, a method for detachably fixing a cooling module () to a assembly support () of a front end of a motor vehicle is proposed.
