Interested contraptions were presented in the Technics University of Varna today. The exhibition is part of the Week of the Patent Department and protection of the industrial property of Bulgarian universities that begins today. The Technics University of Varna is the host of the events.

The not-yet-patented ship control device was a particular interest of the day. Docent Nikola Petrov, part of the team that worked on the new device explained that the additional steering wheel in front of the propeller hub helps the ships go backwards not only to the left, but also straight or to the right. The current systems provide a steering wheel only behind the propeller hub. With the new addition, the backwards sail of the vessels can be controlled.
