    • The amplitude and phase errors of the modulation and demodulation in a transceiver are corrected by a self-calibration procedure in which a test signal is applied to the baseband input of the transmitter, and the output of the modulator is looped back to the input of the demodulator. The amplitude and phase errors of the resulting signal at the baseband output of the receiver are detected, and the contributions of the transmitter and receiver to the errors are separated and resolved into amplitude and phase components. Adjustments are then made to the amplitude and phase balance in the transmit and receive signal paths to correct the errors.
    • 收发器中的调制和解调的幅度和相位误差通过自校准程序来校正,其中测试信号被施加到发射机的基带输入,并且调制器的输出被环回到 解调器。 在接收机的基带输出端产生的信号的振幅和相位误差被检测到,发射机和接收机对误差的贡献被分离并分解成幅度和相位分量。 然后对发射和接收信号路径中的幅度和相位平衡进行调整,以纠正误差。

    • A cervical canal dilator having an elongate tubular shaft that defines at least two internal lumens that are juxtaposed to a longitudinal axis. A first inflatable member is positioned on the outer surface of the shaft and is in communication with the first lumen. While a second inflatable member is also positioned on the outer surface of the shaft. The second inflatable, however, is longer than and completely covers the first inflatable member. Additionally, the second member is fabricated of a non-elastic material that limits the inflation of the second member to a predetermined maximum diameter of inflation. The device, also, has a control system which controls the fluids and/or gases that enter the lumens.

    • A hatch cover for deployment over a hatchway formed in a floating roof liquid storage tank permits rapid loading and unloading of inspection or maintenance equipment and minimizes vapor emissions from the tank. The portable hatch cover has two base plates movably connected at a hinge and each defining complementary recesses. A circular flange extends from the bottom surfaces of the base plates to seat the hatch cover in the hatchway. Two door panels are movably connected at hinges to the top surfaces of the base plates. When one or both of the door panels are opened, equipment may be loaded into the tank through the complementary recesses. When closed, the door panels cover the recesses in the base plates. Complementary notches in the door panels provide an opening through which equipment tubing or wiring may extend when the door panels are closed. A collar gasket optionally may be wrapped around the tubing or wiring as a further means to limit vapor emissions from the tank.
    • 用于部署在浮顶液体储罐上形成的舱口的舱口盖允许快速装载和卸载检查或维护设备,并最小化来自罐的蒸气排放。 便携式舱口盖具有两个基板,可移动地连接在铰链处,每个限定互补的凹槽。 圆形凸缘从基板的底面延伸,将舱口盖安置在舱口中。 两个门板在铰链处可移动地连接到基板的顶表面。 当一个或两个门板打开时,设备可以通过互补的凹槽装载到罐中。 关闭时,门板覆盖基板上的凹槽。 门板上的互补凹口提供了一个开口,当门板关闭时,设备管道或接线可以通过该开口延伸。 套环垫圈可以任选地缠绕在管道或接线上,作为限制来自罐的蒸气排放的另一种手段。

    • The invention provides a low density paperboard material and associated method for use in producing an insulated container, and is especially well-suited for making cups. The paperboard material comprises a paperboard web including wood fibers and expanded microspheres, and has a relatively low density ranging from about 6 to about 10 lb/3MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80×10−3 ft−lbf., preferably at least 100×10−3 lft−lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparable to higher cost materials conventionally used to make cups. Also, the surface of the low density board may have a Sheffield smoothness of 300 SU or greater compared with the surface smoothness of 160 to 200 SU for conventional cupstock, the latter having been thought necessary for adequate print quality. However, it has been found that the low density board exhibits good printability on flexo printing machines despite its relatively rough surface, which is surprising and bonus effect realized along with the insulative and other properties of the board.
    • 本发明提供一种用于制造隔热容器的低密度纸板材料和相关方法,特别适用于制造杯子。 纸板材料包括包含木纤维和膨胀微球的纸板网,并且具有约6至约10lb / 3MSF / mil的相对较低的密度,约24至约35密耳的相对较高的厚度,以及内部键 至少约80×10 -3 ft-lbf,优选至少100×10 -3ft-lbf的强度。 对于诸如杯子的应用,材料也在一侧或两侧上涂覆有阻隔涂层,优选低密度聚乙烯,以限制液体渗透到网中。 本发明的低密度纸板材料可转换用于制造容器,特别是杯子,并具有与常规用于制造杯子的较高成本材料相当的绝缘性能。 此外,低密度板的表面可以具有300SU或更大的谢菲尔德平滑度,与常规杯状物的160至200SU的表面平滑度相比,后者被认为对于足够的打印质量是必要的。 然而,已经发现低密度板在柔版印刷机上表现出良好的印刷性,尽管其表面相对粗糙,这与板的绝缘性和其它性能一起实现了令人惊奇的效果。
