Abstract: An extremely white water absorbent fiber having a high percentage of total dietary fiber and hemicellulose and a low concentration of lignin and silica is disclosed. The dietary fiber is formed by subjecting ground oat hulls to an alkaline digestion at elevated temperatures and pressures. The digested oat hulls are then filtered, neutralized and bleached to form the desired end product. The formed fibers are comparable or better than fibers formed by digestion of wood products. These fibers can be added in high concentrations to bakery products, particularly bread, without imparting a gritty feel to the bread or causing significant discoloration of the bread.

Abstract: A current leakage control circuit regulates the output power of an electrosurgical generator to limit the amount of leakage current. The leakage current is monitored with a differential transformer which has the output and return leads of the electrosurgical generator as first and second windings. A third or sense winding produces a control signal whenever the currents in the output and return leads are not equal, thus indicating current leakage. The control signal is compared to a predetermined maximum safe level of leakage current. If this predetermined level is exceeded, a power control feedback loop of the electrosurgical generator reduces the output power to a sufficiently lower level to reduce the leakage current within a maximum acceptable limit.
