    • A self-excited microelectromechanical device is described. The device includes a resonating structure, such as a cantilever, which responds to a physical phenomenon by generating an induced variable frequency voltage signal corresponding to the physical phenomenon. Self-excitation circuitry connected to the cantilever processes the induced variable frequency voltage signal and produces a variable frequency voltage signal in a resonant pass band of interest that is applied to the cantilever to augment the effect of the physical phenomenon on the cantilever. An exemplary use of the device is as a power line sensor. In this context, the cantilever responds to the electric field associated with a power signal on a power line. The cantilever transforms the voltage signal of the electric field into a corresponding frequency signal. The noise-immune frequency signal can be readily transmitted and processed to reconstruct the power signals carried by the power line. When the device is used as a power line sensor, the self-excitation circuitry can be powered by a voltage established through differential electrostatic fields created by the power line. Thus, the device can operate on the power line without an internal power supply.
    • 描述了一种自激式微机电装置。 该装置包括诸如悬臂的谐振结构,其通过产生对应于物理现象的感应可变频率电压信号来响应物理现象。 连接到悬臂的自激电路处理感应的可变频率电压信号,并在感兴趣的谐振通带中产生可变频率电压信号,该信号被施加到悬臂上以增加悬臂上的物理现象的影响。 该装置的示例性用途是电力线传感器。 在这种情况下,悬臂响应与电力线上的功率信号相关联的电场。 悬臂将电场的电压信号转换成相应的频率信号。 噪声免疫频率信号可以容易地传输和处理,以重建由电力线携带的功率信号。 当该设备用作电力线传感器时,自励电路可以由通过由电力线产生的差分静电场建立的电压供电。 因此,该装置可以在没有内部电源的情况下在电力线上操作。

    • In accordance with a preferred embodiment of this invention, a controlled phase change is used to trigger an exothermic polymerization reaction in an injection molding process. The subject method comprises first, dispersing a crystalline urea reactant, 1,3-bis-(3-isocyanatotolyl) urea, in a liquid polyoxyalkylene polyol or mixtures thereof. Since the polyols do not dissolve the urea at room temperature, the dispersion is storage stable over an extended period of time. This is unexpected because the isocyanate and hydroxyl functionalities are normally quite reactive. In the barrel of the injection molding machine, the dispersion is heated to a temperature at which the polyol will begin to dissolve and thereby react with the crystalline urea to initiate a controllable polyurethane-forming reaction. At present, the specific urea disclosed above is preferred because of its ability to (1) form a storage stable dispersion, (2) dissolve in the polyol at a temperature below its decomposition temperature, and (3) react with the polyol at controllable rates once it has dissolved. All three properties are important to this invention and they enable the practitioner to use conventional injection molding equipment.
    • 根据本发明的优选实施方案,使用受控相变来引发注射成型工艺中的放热聚合反应。 本发明的方法包括首先将结晶尿素反应物,1,3-双(3-异氰酸基吗啉基)脲分散在液体聚氧化烯多元醇或其混合物中。 由于多元醇在室温下不溶解尿素,所以分散体在长时间内保持稳定。 这是意想不到的,因为异氰酸酯和羟基官能团通常是相当反应的。 在注射成型机的桶中,将分散体加热到多醇开始溶解的温度,从而与结晶尿素反应以引发可控的聚氨酯形成反应。 目前,上述特定的尿素是优选的,因为它能够(1)形成储存稳定的分散体,(2)在低于其分解温度的温度下溶于多元醇,和(3)以可控速率与多元醇反应 一旦解散了 所有三种性质对于本发明是重要的,并且它们使得从业者能够使用传统的注塑设备。

    • Carbon dioxide, from a greenhouse gas source, is reacted with hydrogen, developed in an environmentally friendly process, such as from solar energy based electrolysis, to produce a mixture of ethanol and other saleable organic compounds. The ethanol and other saleable organic compounds mixture may contain substantial percentages of methanol, ethanol, and dimethylether in addition to other components which have chemical structures of predominantly carbon and hydrogen or carbon, hydrogen and oxygen. The saleable organic compounds, such as methane, methanol and ethanol may be used as a combustible fuel thus developing a green energy cycle. A portion of the organic compounds may be separated into essentially pure components and used as chemical process feed stocks. The essentially pure organic compounds may be further reacted with suitable chemical compounds to modify said organic compounds. A portion of the organic compounds may be sequestered for long or short time periods by placing them in suitable storage thus providing a mechanism for sequestering carbon dioxide and storing
