Abstract:
The invention relates to an underwater antenna apparatus comprising a non-stationary antenna, an extension device and a return positioning device, wherein an extension force in an extension force direction can be impressed by the extension device of the antenna and a counterforce acting in opposition to the extension force in a counterforce direction can be impressed by the return positioning device of the antenna, characterized in that the return positioning device or part of the return positioning device is configured so as to be non-stationary in a defined manner, with the result that by changing the location in a defined manner, the antenna can be positioned in a retracted position, an extended position or an intermediate position.
Abstract:
The invention relates to a method and to a device for launching an underwater moving body (4, 5). In order to reduce the expenses arising from furnishing watercraft, a land-supported deployment of underwater moving bodies in coastal waters using a launching device is provided with a land-based carrier system for transporting the underwater moving body (4) and a corresponding land-based deploying system.
Abstract:
The invention relates to a fiberglass spool comprising a self-supporting roll (12) having layers of windings (20) located one above the other of an optical fiber (13) for transmitting data that may be unwound from the interior of the roll outwards, wherein the windings (20) are fixed to one another by means of an adhesive bonding agent. In order to realize a sufficiently stable, self-supporting roll (12) that may be reliably unwound from the inside outwards without loops being pulled out of the roll (12), the roll (12) is structured as a cross-winding and a hydrocarbon-based, salt water-resistant, chemically inert impregnating material that may be liquefied by heating is used as the bonding agent.
