Title: Johann Seferiadis: Innovator in Cryogenic Technology
Introduction
Johann Seferiadis is a notable inventor based in Julich, Germany. He has made significant contributions to the field of cryogenic technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is for a "Container having a hot wall with a high-temperature-tolerant current." This invention features a current pass-through arrangement for a rodlike electrode that passes perpendicularly through a hot wall of a container. The design includes an inner seal and an outer seal, with the outer seal positioned at a cooler location than the hot wall. The electrode is tightly fitted into a cylindrical bushing made of electrically insulating material, projecting out of the bushing at the container-adjacent end. The bushing is then fitted into a wall element that defines an annular space filled with sealing material. Another significant patent is for a "Pump for very cold liquids." This pump is designed for cryogenic liquids and features a Dewar flask construction. It includes a submerged multistage rotary pump suspended from the flask's mouth, with a thermal insulation system to prevent heat flow. The design allows for the immediate operation of the pump after a quiescent period, ensuring efficient pumping of liquid air or liquid nitrogen.
