    • Apparatus and method for feeding particulate material from a hopper into a process stream at a controlled flow rate. A rotating wheel with spaced apart pockets is vibrated to densify the particulate material in the pockets. A stator contacts and covers a portion of the upper surface of the wheel and has a transfer station connected to discharge particular into the process stream. The wheel is driven in rotation at a controlled rate to control the particulate flow rate into the process stream. A conveying gas supply projects a jet of gas into the pockets for removing the particulate material and conveying it into the process stream. An aerating gas supply directs an upward flow of gas from the periphery of the wheel, through the particulate material being supplied to the wheel to fluidize the particulate material supplied to the wheel.

    • A biodegradable hydrogel has been made based on high concentrations of whey protein isolate (WP1). WP1 gels of different compositions were fabricated by thermally inducing gelation of high-concentration suspensions of protein, and characterized for compressive strength and modulus, hydration swelling and drying properties, mechanical behavior change due to polysaccharide additives, and intrinsic pore network structure. The gels were shown to be compatible with bone cells and could be used as bone tissue scaffolds. In addition, WP1 fibers were produced by electrospinning. Several additives could be incorporated into the WPI gels, including structural additives, growth factors, amino acids, etc. The WP1 hydrogels can be made with glycerol to increase flexibility and stability. The hydrogels could be used for tissue regeneration, food protection, controlled-release applications (including drug encapsulation, dietary supplement release, attractant release in lures, nutrient release to plants (fertilizers), column packing for compound separation, and membrane development.
    • 基于高浓度的乳清蛋白分离物(WP1)制备了可生物降解的水凝胶。 通过热诱导蛋白质的高浓度悬浮液的凝胶化制造WP1不同组成的凝胶,其特征在于抗压强度和模量,水合膨胀和干燥性能,由于多糖添加剂引起的机械性能变化和固有孔网络结构。 凝胶显示与骨细胞相容,可用作骨组织支架。 此外,WP1纤维通过静电纺丝生产。 WPI凝胶中可以加入几种添加剂,包括结构添加剂,生长因子,氨基酸等。WP1水凝胶可以用甘油制成,以增加柔韧性和稳定性。 水凝胶可用于组织再生,食品保护,控制释放应用(包括药物包封,膳食补充剂释放,诱饵引诱剂释放,植物营养释放(肥料),用于化合物分离的柱填充和膜发育。

    • A reference-free direct digital lock-in system (RDDL 10) has a first input coupled to a periodic electrical signal and an output for outputting an indication of a magnitude of a desired periodic signal component. The RDDL also has a second input for receiving a signal (9) that specifies a reference period value, and operates to autonomously generate a lock-in reference signal having a specified period and a phase that is adjusted to maximize a magnitude of the outputted desired periodic signal component. In an embodiment of a measurement system that includes the RDDL 10 an optical source provides a chopped light beam having wavelengths within a predetermined range of wavelengths, and the periodic electrical signal is generated by at least one photodetector that is illuminated by the chopped light beam. In this embodiment the measurement system characterizes, for at least one wavelength of light that is generated by the optical source, a spectral response of the at least one photodetector. The RDDL can operate in nonreal-time upon previously generated and stored digital equivalent values of the periodic electrical signal or signals.
    • 无参考的直接数字锁定系统(RDDL 10)具有耦合到周期性电信号的第一输入和用于输出期望的周期信号分量的幅度的指示的输出。 RDDL还具有用于接收指定参考周期值的信号(9)的第二输入,并且操作以自主地生成具有指定周期的锁定参考信号和被调整以最大化输出期望值的幅度的相位 周期信号分量。 在包括RDDL 10的测量系统的实施例中,光源提供具有预定波长范围内的波长的短切光束,并且周期性电信号由被切碎的光束照射的至少一个光电检测器产生。 在该实施例中,对于由光源产生的光的至少一个波长,测量系统表征至少一个光电检测器的光谱响应。 RDDL可以在以前生成和存储的周期性电信号或信号的数字等效值的非实时时间内工作。
