Abstract: A non-return valve device has at least part of a flow channel for a fluid and a movable cord-like sealing element arranged in the flow channel. The sealing element is configured such that it can be moved at least partially between a closed position and an open position, wherein, in the open position, a fluid flow is permitted through the flow channel, whereas in the closed position, the fluid flow through the flow channel is blocked by form-fitting engagement with the sealing element.

Abstract: An apparatus for electrically connecting a polyphase vessel distribution system of a vessel to a polyphase land supply system having a supply system connection disposed on land to be connected to a vessel system connection of the vessel distribution system at least in sections by at least one cable connection, enables a fast and secure connection of the land supply system to the vessel distribution system. During normal operation, vessel movements can be reliably compensated by at least one articulated arm used as a support for one or more cable connections. The articulated arm has arm segments interconnected by at least one articulated connection. A joint drive is associated with each articulated connection for mutually pivoting the arm segments interconnected by the articulated connection, which is associated with the joint drive.

Abstract: In order to provide an apparatus for the redundant power supply of at least one load having a first converter, which can be connected to a first AC voltage system via a first connection, a second converter, which can be connected to a second AC voltage system via a second connection, and a DC voltage intermediate circuit, which connects the first converter to the second converter on the DC voltage side, which apparatus makes a redundant power supply possible, the invention proposes that the DC voltage intermediate circuit has at least one load connection for the purpose of supplying power to a load.

Abstract: An adapter received in an opening of a partition wall of a vehicle door connects a cable plug of a cable harness to a module plug of a door control module. The adapter includes a mount for the module plug, a mount for the cable plug, and an abutment face providing a seal at the partition wall. The adapter further includes a latching tab. When the adapter is inserted into the opening, the latching tab flexes outwardly, securing the adapter to the partition wall. The module plug and the cable plug can be inserted into or removed from the adapter without affecting the sealing between the wet area and the dry area of the vehicle door.
