He has made significant contributions to the field of engineering, particularly in the development of methods and devices related to tension members and corrosion protection for cables. With a total of 2 patents, his work showcases a blend of creativity and technical expertise.
Latest Patents
Kellner's latest patents include a method of and device for severing a tension member in a prestressed system. This innovative approach involves a prestressed grouted anchor where a portion of the tension member is grouted in a receiving material. The remaining portion is designed to be separated at a selected breaking point through the application of heat, which reduces the tensile strength of the tension member. This process allows for an automatic severing of the tension member at the desired point.
Another significant patent focuses on the process for manufacturing protection against corrosion for cables made of high-strength steel wires. This invention ensures that cables used as tension members for earth anchors or rock anchors are thoroughly protected against corrosion. The method involves filling the interior spaces between the wires with a corrosion protection material, followed by filling the annular space between the cable and its tubular sheathing member. This dual approach guarantees complete protection for the cables.
