Latest Patents
Roggen's latest patents include an underwater welding apparatus and a self-drilling thermal bolt. The underwater welding apparatus is designed to facilitate welding tasks beneath the water's surface. It features an open-mouthed bell with an axially extending electrode, which is surrounded by a tube that supplies gas under pressure from a floating pumping station. This innovative design allows for the maintenance of a gaseous atmosphere inside the bell, preventing surrounding water from interfering with the welding process.
The self-drilling thermal bolt is another remarkable invention. It consists of an elongated body with a consumable combustible material at its leading end. This design allows the bolt to melt compact materials upon ignition, enabling it to anchor securely within the material. The process ensures that the anchor remains in place until the melted material solidifies, providing a strong and reliable hold.
