摘要： Protein may be removed from fluids by adsorption onto inorganic oxide-silica cogels. Preferred cogels are silica alumina and silica magnesia activated so that the cogel surface is in acid form, with H.sub.0 values less than the pH of the protein-containing fluid which, in turn, is less than the isoelectric point of the protein. The method is particularly effective for removing haze-forming proteins from wine.

摘要： An active vibration control (AVC) system includes a shaft-driven gearbox mounted force generator (GMFG) mounted to a main rotor transmission. The GMFGs receive shaft power from an output shaft driven by the main rotor transmission and/or engine-to-transmission gearbox to avoid separate drive motors.

摘要： A modified physical adsorption process is described in which small quantities of caustic are added to glyceride oils, fatty chemicals or wax esters having an FFA level sufficient to create about 20 to 3,000 ppm soaps. The soaps, together with impurities, are removed by adsorption onto amorphous silica.

摘要： A noise-suppression assembly of a mechanical drive system having a rotational frequency includes an audio filter unit configured to receive a first audio signal and a timing signal of the mechanical drive system. The audio filter unit generates a noise-cancellation signal based on a frequency of the timing signal to suppress a noise generated by the mechanical drive system and to apply the noise-cancellation signal to the first audio signal to produce a filtered first audio signal. The frequency of the timing signal is based on the rotational frequency of the mechanical drive system.

摘要： A dual, counter-rotating, coaxial rotor system provides individual control of an upper rotor system and a lower rotor system. The lower rotor control system and the upper rotor control system provide six controls or “knobs” to minimize or theoretically eliminate airframe vibration. In a dual, counter-rotating, coaxial rotor system, application of a HHC system to the two rotor systems individually but located on the common axis, will yield essentially complete vibration reduction because the 6 controls will suppress the 6 loads.

摘要： Impurities, which may include soaps, gums, phospholipids and pigments, can be removed from chemically or physically refined glyceride oils in a dual phase adsorption and treatment process. In the first phase, the oil is contacted with amorphous silica to remove phospholipids and soaps or gums or both. In the second phase, the oil is passed through a packed bed of a pigment removal agent for decolorizing glyceride oils.
