Title: Innovations of Hans J Goettler
Introduction
Hans J Goettler is a notable inventor based in Fargo, ND (US), recognized for his contributions to the field of polymeric materials. He holds a total of five patents, showcasing his innovative approach to solving complex problems in material science.
Latest Patents
One of his latest inventions is a shear mixer designed for polymeric materials. This mixer features two mateable bodies that, when pressed together, create a reverse flow path for the material being mixed. The design includes two mixing gaps, each defined by a primary wall surface on one body and an opposing wall surface on the other. The contractive movement of the two bodies increases the linear length of each mixing gap, while also causing one wall of each gap to move in a direction opposite to the flow of material. This innovative mixing method not only enhances the length of the mixing gap but also facilitates a unique flow of material through the mixer.
Another significant patent is the rheo-photoacoustic Fourier-transform infrared spectroscopic method and apparatus. This invention allows for the examination of rheological properties of materials at a molecular level. The apparatus consists of an IR spectrometer and a photoacoustic cell, which generates frequency-domain photoacoustic information of a specimen under various static load conditions. By analyzing relative changes in amplitudes of certain bands in the spectra, the apparatus can detect the behavior or failure modes of molecular bonds within the material.
