Novel Lubrication for MAF Processing

Executive SummaryManual labor remains one of the most expensive operating costs for machine shops. This MSU-developed technology seeks to improve the use of Magnetic Field-Assisted Finishing (MAF) to reduce the amount of hand finishing, particularly for mold cavities. Additionally, this technology seeks to improve the lifetime of abrasive particles,...

Chemical Efficacy, Environmental Safety, and Operational Design Improvements for the SandSprayer "Spreader Apparatus for Sand Based Formulations" (Patent No. 8,028,928)

Executive SummaryCurrently, as a part of turfgrass installation and maintenance, topdressing sand and active ingredients (fungicide/growth regulators) are applied sequentially, requiring two passes over the turf. Carrying out these processes separately requires additional time to make two identical passes, leads to spray drift when spraying chemicals,...

Quasi-Static Self-Powering, Sensing, and Data Logging

Executive SummarySlowly acting events can be very difficult to sense, especially for self-powered sensors. Most sensors require an external energy source in order to detect the desired property and report results. For some applications however, a self-powered sensor is desirable that uses energy from the object being sensed in order to record the data....

Radial Wave Rotor (Wave Disc)

IntroductionTraditional attempts to use depressions or pockets to control wave reflection of off-design operation in internal combustion engines undesirably reduce the sensitivity of axial wave rotors to engine speed changes. Nevertheless, there still exists a need to improve the performance and reduce the size of traditional wave rotors to enhance...
