Latest Patents
Kassfeldt's latest patents include a method and device for determining rheological properties. This invention focuses on measuring the rheological properties of high-density slurry materials, specifically high-density mill tailings. The method involves placing a sample of the tailings in a mixing tub, where a mixing paddle, driven by a digitally controlled electric motor, mixes the material at a constant speed. Feedback control elements, including a variable speed drive and a computer, monitor the mixing speed and adjust for any deviations. The system allows for real-time determination of rheological properties by correlating torque to speed.
Another significant patent is the flasher device for lamps. This two-terminal flasher device is designed for flashing automobile lamps and serves as a replacement for traditional thermal devices. It utilizes an electro-mechanical relay to control the flashing rate through an electronic circuit. The device is powered by a capacitor that charges from the battery and discharges when the power source is unavailable. This innovative design ensures an 'instant-on' operation and includes features to detect lamp failures by adjusting the flashing rate.
