Abstract: A golf putter head is made entirely of pottery clay and can have a glazed body and an unglazed striking face. This putter head is preferably fabricated by forming a basic disc shape on a potter's wheel and then removing a portion of the disc shape away to form a striking face. The putter head can also be formed in a ram press. A putter with a mallet shaped head can be formed or the putter can have an elongate shape other than a mallet shaped head. After drying, the clay can be glazed and then fired. The dried clay is then cut to form a planar striking face. The putter head can alternatively be fabricated using a ram press molding technique or can be initially formed on a pottery wheel and then molded to a final shape in a ram press.

Abstract: A system and method is provided that improves the under frequency response of gas turbines by providing a fast-response power augmentation system. The system includes a tank storing a blended mixture of motive fuel such as ethanol or methanol and demineralized water in a predetermined ratio that is provided as a diluent to be injected into the compressor bellmouth, the Compressor Discharge Chamber (CDC), and/or the combustion system via one to three dedicated circuits. To achieve the instantaneous injection of the diluent at the correct pressure and for the appropriate duration to meet the needs of the gas turbine Grid compliance mandate, an accumulator is used as the motive force to drive the augmentation fluid in the dedicated circuits. The injected diluent is microprocessor controlled to either be simultaneous into all three circuits or is sequenced based on a determination of the best turbine control and performance.
