Abstract: A porous biomass support system in a bioreactor affords biodegradation of phenolic materials to a level under 20 parts per billion at a hydraulic residence time of about 15 hours with significantly less sludge formation currently possible by available methods. The porous biomass support system comprises a hydrophilic polymer, preferably polyurethane foam, small particles of activated carbon and suitable microorganisms, which are entrapped with the polymer material. The carbon is self-regenerative and does not have to be periodically replaced or replenished. The entire porous biomass support system can operate for extended periods of time without replacement.

Abstract: The sealed tapered roller bearing assembly (10, 111, 211, 311) of the present invention comprises a bearing assembly (10, 111, 211, 311) which may be removed or serviced without destroying or damaging the assembly (10, 111, 211, 311). Inner and outer races (30, 40) contain tapered rollers (60) therebetween, and a positioning ring (70) is disposed intimately about the outer race (40) as a result of the outer race (40) and ring (70) being press-fitted together. The ring (70) extends from an axial portion (76) to a radial portion (78) which becomes an angled feed tapered section (80) that extends into a first end member axial part (82). The tapered section (80), axial part (82) and a dam seal (90) define a lubricant dam area (100) about a first end of a space (95) between the races (30, 40). A second end of the space (95) between the races (30, 40) is enclosed by a composite seal member (120, 121, 221, 321) that has a first resilient foot, end, portion, or arm (124, 125, 214, 312) engaging an axial extension (72) of the axial portion (76) of the ring (70), and a second resilient foot or lip (126, 126A, 224, 324) engaging the inner race (30). For service or inspection, the entire bearing assembly (10, 111, 211, 311) may be removed easily, or just part of the bearing assembly may be removed, all without damaging or destroying the assembly (10, 111, 211, 311).

Abstract: Magnesium base metal alloy sheet is produced by rolling the rolling stock extruded or forged from a billet at a temperature ranging from 200 °C to 300 °C. The billet is consolidated from rapidly solidified magnesium based alloy powder that consists of the formula MgbalAlaZnbXc, wherein X is at least one element selected from the group consisting of manganese, cerium, neodymium, praseodymium, and yttrium, 'a' ranges from about 0 to 15 atom percent, 'b' ranges from about 0 to 4 atom percent, 'c' ranges from about 0.2 to 3 atom percent, the balance being magnesium and incidental impurities, with the proviso that the sum of aluminum and zinc present ranges from about 2 to 15 atom percent. The alloy has a uniform microstructure comprised of fine grain size ranging from 0.2-1.0 νm together with precipitates of magnesium and aluminum containing intermetallic phases of a size less than 0.1 νm. The sheets have a good combination of mechanical strength and ductility and are suitable for military, space, aerospace and automotive application.

Abstract: Light rising solvent vapors have a neutral tendency to rise upwardly out of the tank by following a convection flow path generally along the inner surfaces (29) of the sidewalls (16) and upwardly past the uppermost edges (40) thereof. To control the expulsion of vapors into the surrounding ambient environment, the uppermost edges are formed with a downwardly and inwardly turned lip (40') coextensive with the length and width of the tank. The lip intercepts the convection flow path to deflect the light rising vapors both inwardly and downwardly back towards the condenser coil. The invention also discloses a removably attachable tank extension (50) which may be attached to the existing tank sidewalls to increase the freeboard height of the tank. The uppermost edges (64, 65) of both the existing tank sidewalls and the tank extension sidewalls may be formed with a downwardly and inwardly turned lip to intercept the convection flow path. The tank extension may be pinned and thereby secured to the existing tank sidewalls at various elevations to optimize the freeboard height as a function of the boiling temperature of the solvent being used.

Abstract: A digital motor controller (10) employs a digital signal processor (70) to generate commutation commands that drive and brake a motor (14). The commutation commands are pulse width modulated. To avoid shoot-through, the digital signal processor (70) automatically adjusts the widths of the pulses according to the amount of current being drawn by the motor (14). Motor speed is measured by taking the difference between consecutive samples from a position sensor and dividing the difference by the sampling time. The digital signal processor (70) also closes position, speed and current loops. The commands provided by each loop are limited between upper and lower limits. Further, the digital signal processor (70) automatically adjusts the upper and lower limits to compensate for changes in design characteristics due to viriations in temperature. The digital motor controller (10) can be used to control different motors (14) having different design characteristics simply by reprogramming the upper and lower limits. A plurality of digital motor controllers (10) can be used to control motors (14) operating in tandem.

Abstract translation: 数字电动机控制器（10）使用数字信号处理器（70）来产生驱动和制动电动机（14）的换向指令。 换向指令是脉宽调制的。 为了避免直通，数字信号处理器（70）根据由电动机（14）吸取的电流量自动调节脉冲的宽度。 通过从位置传感器获取连续样本之间的差异并将差除以采样时间来测量电机速度。 数字信号处理器（70）还关闭位置，速度和电流回路。 每个循环提供的命令都限制在上限和下限之间。 此外，数字信号处理器（70）自动调节上限和下限以补偿由于温度变化引起的设计特性的变化。 数字电动机控制器（10）可以简单地通过重新编程上限和下限来用于控制具有不同设计特性的不同的电动机（14）。 多个数字马达控制器（10）可用于控制串联运行的马达（14）。
