    摘要： A high-rate hydrothermal cleanup (HCU) process and system is disclosed for the rapid hydrolysis of renewable oils and reduction of inorganic and organic contaminants, such as salts, minerals, metals, asphaltenes, polymers, and coke precursors in both renewable oils and petroleum fractions. The process and system is characterized by a very short residence time, high-temperature, high-pressure, turbulent flow, hydrothermal operation. The HCU and integrated vapor-liquid separation system and process results in high yields of oil product that contains significantly reduced concentrations of inorganic and organic contaminants. The process may be operated to produce a concentrated clean glycerin byproduct and short-chain and long-chain free fatty acid product streams. The integrated vapor-liquid separation system and process performs at near atmospheric pressure by taking advantage of the water employed in the cleanup process and the energy imparted by the HCU reactor and eliminates the need for vacuum distillation.

    摘要： An improved hearing protection device intended to be inserted into an external auditory meatus of a user, having a housing structure (2), a passive tuning element (12), and a passive, nonlinear acoustic filter (11). The tuning element (12) and the acoustic filter (11) may be supported in series by the housing structure (2). The tuning element (12) may be or include a diaphragm (122), a resonator (121), or both. The housing structure (2) may support a diaphragm (122) of the tuning element (12) at its circumference, and may provide cavities (23A, 23A1) on both sides of the diaphragm (122). In some embodiments electronic components are included in the hearing protection device to counteract insertion loss provided by the passive element (1), and restore natural hearing for low to moderate sound pressure levels. Communications devices may also be incorporated into the hearing protection device.
