Title: Innovations of Johannes G. Schindler
Introduction
Johannes G. Schindler is a notable inventor based in Marburg, Germany. He has made significant contributions to the field of measurement technology, particularly in the determination of oxygen partial pressure in various environments. With a total of 12 patents to his name, Schindler's work has had a profound impact on both medical and industrial applications.
Latest Patents
One of Schindler's latest patents is a measuring apparatus designed for the determination of oxygen partial pressure in liquids and gases. This innovative device features a substantially sheathed metallic cathode with a small, unsheathed metallic surface and a metallic anode. It includes an ion impermeable but gas permeable membrane that is interposed between the material whose oxygen content is to be measured and the unsheathed metallic surface of the cathode. Additionally, an electrolyte is placed between the cathode and anode, along with a barrier layer that is impermeable to cations of the material forming the anode. Preferably, the metallic anode is a silver anode enveloped with silver chloride, which is covered with the barrier layer.
Another significant invention is the polarographic catheter probe. This catheter-shaped probe is designed to determine analytical data of biological fluids from humans, animals, or plants. It consists of a cathode, an anode, and an electrolyte connecting the two, all surrounded by a flexible sheath. The tip region of the cathode is sealed by an ion-impermeable but gas-permeable membrane. The anode is positioned at the distal end of the catheter shaft, away from the cathode tip, allowing for effective measurement of fluid properties.
