Abstract: A pressing tool has two grips movable relative to one another, a crimping unit with a crimping drum arranged in a tool head of the pressing tool and having at least one crimping die and a depository for storing a strip of ferrules connected to one another as a belt. The tool also includes a transport device movable in a prestressed manner toward the crimping drum to transport the ferrule strip from the depository toward the crimping drum. The transport device has a transport plate and a transport lever pivotably arranged and sprung relative to the transport plate. The transport lever has an attachment close to the crimping drum that can be pressed in between adjacent ferrules there arranged. The attachment is arranged between the transport device and a support surface of a head cap. There is a holding-down device which is spring supported on the support surface and which presses the transport plate against the transport lever.

The base of the node element is mounted on the first pressing jaw via the first pivot axis and a first of the limbs is mounted on the second handle via a second pivot axis. When the pliers mouth formed by the sections of the pressing jaws remote from the handles is opened, the second limb of the node element is pivoted in the direction of an upper outer rim of the first pressing jaw, the outer rim being remote from the second pressing jaw.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A plug connector and a method of coding of same is characterized by first and second coding elements that are pre-mountable as a unit on at least one of a pair of plug connector components. The other plug connector component is configured so that when the connector components are initially connected together in an axial direction, one of the coding elements is connected with one of the components and the other coding element is connected with the other component. When the components are separated axially, the respective coding elements are separated so that each are retained on the component with which it was originally connected.

Abstract: A pliers-type insulation stripping tool includes a releasable fastening device for fastening a knife cassette to at least one of the knife carrier members that are longitudinally displaced by the pivotally connected tool handle members to remove a severed length of insulation from a longitudinally-arranged insulated conductor that is clamped between by the tool gripping jaws. A U-shaped resilient fastener spring wire has leg portions that are resiliently biased apart, at least one of the legs containing a laterally extending bulge portion that extends into a corresponding locking slot contained in a side wall of the knife cassette. To release and replace the knife cassette, the protruding free extremities of the leg portions of the spring wire are displaced together, thereby to remove the leg bulge portion from the slot contained in the cassette outer wall.
