    • Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.
    • 超高分子量聚α-烯烃的聚合物浆料通过用蜡和任选的相对高密度颗粒的组合的表面处理而稳定地沉降,分离和附聚。 表面涂层的选择不仅用作防粘剂或分隔助剂以保持粘性聚合物颗粒分离,而且还提供具有与载体匹配的密度的悬浮聚合物颗粒。 这样可以防止淤浆组分随时间分离。 最终用作管道添加剂以减少流体阻力并增加体积通量的这种材料可以长时间储存​​和运输而不降低浆料质量。 注入管道后,聚合物颗粒快速溶解,不受涂层的阻碍。

    • A method of identifying a flaw in a part is provided that includes vibrating a part to induce heat. The heat originates in any flaws in the part. A thermal image is obtained using, for example, an infrared camera. A mathematical representation of the thermophysics, such as the heat conduction or thermal energy equations using the boundary element method or finite element method is used to identify a source and an intensity of the heat identified with the thermal image. Using the source and intensity of the heat, flaw characteristics for the part can be determined. The method is employed using an inspection system that includes a vibration device for vibrating the part. An imaging device, such as an infrared camera, measures temperature on the surface of the part. An assumption is made or additional measurements are taken to obtain values for surface flux or surface heat transfer coefficients. A processor communicates with the imaging device for receiving the surface temperature. The processor includes computer memory having part characteristics and mathematical equations. The processor uses the measured surface temperature, assumed or measured heat flux or heat transfer coefficients, part characteristics and mathematical equations to determine the flaw characteristics in the part.

    • Three-way call detection is an important component of correctional facility telephone equipment because it helps restrict calling access by certain persons to certain restricted telephone numbers. Various three-way call detection methods exist, but all of these implementations suffer from one major limitation-the detection accuracy is not as high as is desired by the industry. The present invention improves detection accuracy, using “steganography.” Steganography involves hiding one set of data or signals within another signal or carrier in such a way that its presence is typically imperceptible to the human ear, and potential even the originator of the carrier signal. The present invention involves a device that connects to a telephone, either at the line or the handset interfaces, and produces a known signal that is steganographically hidden within the user's normal voice signal. Detection equipment, residing at another location, monitors signals on telephone calls and tests for the presence of the hidden signal or data generated by the invention. Once detection is achieved, appropriate action, such as terminating or recording the call, may be taken. Improved accuracy is achieved by choosing the appropriate hidden signal(s). Once detected, the presence of the signal guarantees the call was made to the restricted party from a particular phone line.
    • 三通呼叫检测是惩教设施电话设备的重要组成部分,因为它有助于限制某些人的呼叫接入某些受限电话号码。 存在各种三路呼叫检测方法,但是所有这些实现都受到一个主要限制 - 检测精度不如业界期望的那么高。 本发明使用“隐写术”来提高检测精度。 隐写术涉及在另一个信号或载体中隐藏一组数据或信号,使得其存在通常对于人耳是不可察觉的,甚至潜在甚至载波信号的发起者。 本发明涉及在线路或手机接口处连接到电话的设备,并且产生被隐写在用户的正常语音信号内的已知信号。 驻留在另一位置的检测设备通过电话监视信号并测试本发明产生的隐藏信号或数据的存在。 一旦检测到,可以采取适当的动作,例如终止或记录呼叫。 通过选择适当的隐藏信号来提高精度。 一旦被检测到,信号的存在就保证了从一个特定的电话线路向限制方发出呼叫。
