Title: Jerzy W Doerffer: Innovator in Life-Saving Technologies
Introduction
Jerzy W Doerffer is a notable inventor based in Sopot, Poland. He has made significant contributions to the field of life-saving devices and marine technology. With a total of three patents to his name, Doerffer's innovations reflect his commitment to enhancing safety in offshore environments.
Latest Patents
One of his latest patents is a free fall submersible life-saving device designed for offshore structures. This device features a spherical pressure shell encased in a protective casing. The upper part includes a lifting frame and at least one manhole that is securely closed with a cover. The lower section is equipped with ballast, an anchor, and a windlass for the anchor rope, which has automatic control of the tension. The device is launched via a catapult from the offshore structure, allowing it to move horizontally in free fall until it reaches the water surface. Once submerged, it anchors itself until it is ready to resurface by releasing the anchor for rescue operations.
Another significant invention by Doerffer is a braking rudder device. This device consists of a turning rudder blade, horizontal plates, and a fixed rudder post. It is characterized by a unique design that divides the rudder blade in the plane of symmetry into two independently turning blades. These blades can rotate up to 110 degrees around their common axis and are connected by hinges. The trailing edge of each blade is shaped like a wedge, and they are reinforced by horizontal plates. In extreme outboard positions, these plates bear upon the rudder post, and vertical flaps fitted along the trailing edges can turn by an angle of up to 90 degrees.
