摘要： A high temperature ultrasonic probe and a mounting fixture for attaching and aligning the probe to a steam pipe using blind alignment. The high temperature ultrasonic probe includes a piezoelectric transducer having a high temperature. The probe provides both transmitting and receiving functionality. The mounting fixture allows the high temperature ultrasonic probe to be accurately aligned to the bottom external surface of the steam pipe so that the presence of liquid water in the steam pipe can be monitored. The mounting fixture with a mounted high temperature ultrasonic probe are used to conduct health monitoring of steam pipes and to track the height of condensed water through the wall in real-time.

摘要： A system and method for monitoring the properties of a fluid, such as water, in a steam pipe without mechanically penetrating the wall of the pipe. The system uses a piezoelectric transducer to launch an ultrasonic probe signal into the pipe. Reflected ultrasonic signals are captured in a transducer, which can be the same transducer that launched the probe signal. The reflected signals are subjected to data processing, which can include filtering, amplification, analog-to-digital conversion and autocorrelation analysis. A result is extracted which is indicative of a property of the fluid, such as a height of the condensed fluid, a cavitation of the condensed fluid, and a surface perturbation of the condensed fluid. The result can be recorded, displayed, and/or transmitted to another location. One embodiment of the system has been constructed and tested based on a general purpose programmable computer using instructions recorded in machine-readable non-volatile memory.

摘要： A traveling wave pump which employs one or more pairs of interfacing plates to transfer fluid (gas or liquid) from one or more inlets to one or more outlets. At least one of the plates in each pair of interfacing plates is driven so as to produce a flexure traveling wave therein. Actuators incorporating electroactive elements are used to drive the driven plates and create the flexure traveling wave. This wave causes chambers to form between the interfacing plates which move from one end of the driven plate to the other in the direction of the wave. Fluid is drawn into a forming chamber, and eventually the forming chamber closes trapping the fluid therein. The fluid is then transported through the pump by the now completely formed chamber as it propagates along the plate interface. If only one of the interfacing plates is driven, the other remains fixed in that no chambers are formed at its surface. However, where both plates are driven, the traveling waves therein are synchronized and coincident chambers are formed at the surface of both plates, thereby doubling the amount of fluid pumped. In addition, the flow direction can be changed by controlling the phase of the drive signals.
摘要翻译：一种行波泵，其使用一对或多对接口板将流体（气体或液体）从一个或多个入口传送到一个或多个出口。每对接口板中的至少一个板被驱动以在其中产生弯曲行波。采用电动元件的执行器用于驱动从动板并产生弯曲行波。该波形使得在从驱动板的一端向波浪方向移动的接口板之间形成室。流体被吸入成形室，并且最终成形室将其中的流体闭合。然后，当流体沿着板接口传播时，流体被现在完全形成的室传送通过泵。如果只有一个接口板被驱动，另一个保持固定，因为在其表面上没有形成腔室。然而，当两个板被驱动时，其中的行波是同步的，并且在两个板的表面上形成一致的室，从而使被泵送的流体的数量增加一倍。此外，可以通过控制驱动信号的相位来改变流动方向。

摘要： A linear recirculation path unit for a roller bearing includes a linear loading passage, a linear unloading passage, and two direction reversing passages connected to the ends of the linear passages. Instead of simply designing the reversing passages so that the slopes or tangents of the linear and reversing passages are continuous at the connecting points, the reversing passages are arranged so that not only the slopes but also the curvatures of the linear and reversing passages vary continuously throughout the recirculation path, thereby reducing centrifugal acceleration of the rolling elements in the path, with consequent reductions in impact forces on walls of the passages, sliding function, and vibration induced noises.
