    • There is provided a method and apparatus to monitor hardness using laser infrared photothermal radiometry. The emphasis is on the ability of this invention to monitor in a non-contact and non-destructive manner the hardness case depth of industrially heat treated steels. The present invention provides a method and apparatus comprising signal generation and analysis as well as instrumental hardware configurations based on the physical principle of photothermal radiometry. The method comprises (a) irradiating the sample surface with an excitation source of suitable emission wavelength and intensity. (b) producing periodic frequency pulses of the laser beam by means of a modulator in the appropriate frequency range (but not confined to) 0.1-100000 Hz. (c) passing the emitted beam through appropriate optics for beam conditioning (d) splitting the incident beam in two beams using a beam-splitter (e) focusing one of the beams onto a photodiode connected to a lock-in amplifier referenced to the modulator frequency to monitor laser power fluctuations (f) directing the second beam normal or at an angle to the surface of the sample (g) directing the generated infrared emissions from the sample surface to an infrared detector connected to another lock-in amplifier also referenced to the modulator frequency (h) recording the signals obtained from both lock-in amplifiers by a computer (i) processing the obtained signals through proprietary software and pre-calibration curves.

    • Electromagnetic free point tools are configured to determine the free point of a downhole pipe in a wellbore utilizing the amplitude or phase change in a transmitted signal for stressed and unstressed pipe. Certain examples of electromagnetic free point tools comprise a housing, one or more transmitter coils, one or more receiver coils, each coil spaced apart from one another, a power source for applying an oscillating voltage to the one or more transmitter coils which then induces a current in the receiver coil(s), and electronics for measuring the induced current in the receiver coil(s). In another embodiment, at least one of the coils is axially adjustable in position within the tool to permit the relative distance between coils to be adjusted to optimize performance of the tool in various conditions. By measuring the amplitude or phase of the induced current relative to the oscillating voltage, a log of the amplitude or phase is generated while passing the tool through a length of unstressed pipe. This process may be repeated while applying a stress to the pipe to generate a second log. By comparing the amplitude or phase of the first and second logs, the free point of the pipe may be ascertained by determining when and where the two logs diverge. This method can also be used to locate collars and measure pipe thickness.
    • 电磁自由点工具被配置为利用应力和无应力管道的发射信号中的振幅或相位变化来确定井筒中的井下管道的自由点。 电磁自由点工具的某些示例包括壳体,一个或多个发射器线圈,一个或多个接收器线圈,每个线圈彼此间隔开的电源,用于向一个或多个发射器线圈施加振荡电压的电源, 接收器线圈中的电流和用于测量接收器线圈中的感应电流的电子装置。 在另一个实施例中,线圈中的至少一个可在工具内的位置轴向调节,以允许在各种条件下调节线圈之间的相对距离以优化工具的性能。 通过测量相对于振荡电压的感应电流的振幅或相位,在通过一定长度的无压力管道时产生振幅或相位的对数。 在向管道施加应力以产生第二对数时可以重复该过程。 通过比较第一和第二原木的幅度或相位,可以通过确定两个原木发散的时间和位置来确定管道的自由点。 该方法也可用于定位套管并测量管道厚度。

    • A furnace refractory extraction system and method includes a selectively removable bottom portion which is attached to a refractory extraction device associated with a container for drawing the refractory lining of a coreless induction furnace into the container. A plug portion in the furnace bottom is selectively removable to provide access to a bottom wall of the refractory lining. An opening is made in the bottom wall of the lining through which an extractor shaft is inserted and then attached to the removable bottom portion of the furnace bottom. The other end of the shaft is attached to a piston and cylinder assembly associated with the container at the open end of the furnace. When the piston and cylinder assembly is powered, the lining is drawn into the container.

    • A method for an Internet-based software application is used to match specific investors to specific traders and traders' systems by running a set of compatibility algorithms. The compatibility algorithms identify similar qualities between investors and traders and compiles a list of high-incidence matches. Such qualities for the investors include investment tendencies and risk-tolerance criteria, and such qualities for the traders include trading tendencies. The software application will allow a specific investor(s) and a specific trader to broker a trade agreement that will accommodate the requirements for both parties. The software application will also allow a specific investor to implement a risk management strategy, which can be done in, but not limited to, four embodiments: the risk-control embodiment, the risk-control-with-pooling embodiment, the risk-transfer embodiment, and the risk-transfer-with-pooling embodiment.
