Abstract: A heater plate for butt fusion of polyolefin pipe has concentric rings, each with an array of radial bores containing cartridge heaters, and a concentric cavity between the rings to carry wiring from the cartridge heaters. The inner ring components are symmetrical to provide a foundation for uniform surface temperature distribution across the entire area of the inner ring. The outer ring components are coordinated to counterbalance the heat sinks resulting from their asymmetrical configuration so as to increase the likelihood that the uniform surface temperature distribution foundation established for the entire area of the inner ring can be maintained and so that the total diameter of the heater plate, including the outer ring, can be used in fusing pipe.

Abstract: A data fusion workstation apparatus and method utilizes algorithms and can be used for applications such as, e.g., hydrogeological modeling, steady-state hydrological flow modeling, transport uncertainty determination, flow/transport fusion, oil reserve management, water supply development, geo-technical engineering projects, and management decision optimization. The invention uses a spatial continuity model which is extended to 3D and equations are provided for computation of the spatial AR coefficients from a desired covariance function. The data fusion workstation provides more robust optimization iterations by use of an algorithm that includes Trust Region or Step Halving methods to limit the Gauss Newton step in solving non-linear least squares problems. Measurement biases and error parameters, and parameters which define a hydrological flow model can be included in the common set of estimated states. An LSQR or other iterative algorithm is used to reduce the computation time for each step of a nonlinear optimization, thereby allowing computation of problems having a very large number of states. The invention preferably provides transport uncertainty calculations in a fusion post-processing step. The invention allows contaminant measurements to be used with hydraulic head and conductivity measurements for better calibration of flow and transport models.

Abstract: A data fusion workstation provides an apparatus and method for realizing the full potential of geophysical and remote sensing by mathematically integrating sensors with each other. Sensor data from each of a plurality of sensor types are related mathematically to each other through a common site model to produce a fused picture with quantified accuracy. Using the concept of pseudo-data, information in sensor data is made equivalent to data in a statistical correlation model, allowing fusion of model information with sensor data during a data inversion step. The process of data fusion comprises several processing steps, which are executed by various microprocessors in a recursire/distributed/parallel-architecture platform. These steps comprise geophysical inversion, geostatistical Kriging, application of statistical information concepts, implementation of a square root information smoother, and application of likelihood techniques.

Abstract: Apparatus and methods for electroplating metal onto substrates are disclosed. The electroplating apparatus comprise an electroplating cell and at least one oxidization device. The electroplating cell comprises a cathode chamber and an anode chamber separated by a porous barrier that allows metal cations to pass through but prevents organic particles from crossing. The oxidation device (ODD) is configured to oxidize cations of the metal to be electroplated onto the substrate, which cations are present in the anolyte during electroplating. In some embodiments, the ODD is implemented as a carbon anode that removes Cu(I) from the anolyte electrochemically. In other embodiments, the ODD is implemented as an oxygenation device (OGD) or an impressed current cathodic protection anode (ICCP anode), both of which increase oxygen concentration in anolyte solutions. Methods for efficient electroplating are also disclosed.

Abstract: Exposed copper regions on a semiconductor substrate can be etched by a wet etching solution comprising (i) one or more complexing agents selected from the group consisting of bidentate, tridentate, and quadridentate complexing agents; and (ii) an oxidizer, at a pH of between about 5 and 12. In many embodiments, the etching is substantially isotropic and occurs without visible formation of insoluble species on the surface of copper. The etching is useful in a number of processes in semiconductor fabrication, including for partial or complete removal of copper overburden, for planarization of copper surfaces, and for forming recesses in copper-filled damascene features. Examples of suitable etching solutions include solutions comprising a diamine (e.g., ethylenediamine) and/or a triamine (e.g., diethylenetriamine) as bidentate and tridentate complexing agents respectively and hydrogen peroxide as an oxidizer. In some embodiments, the etching solutions further include pH adjustors, such as sulfuric acid, aminoacids, and carboxylic acids.

Abstract: Polyolefin pipes are welded end-to-end by a self-propelled, self-contained machine which performs all steps necessary to the process without need for any other machines or equipment. Hydraulically driven parallel tracks are independently controlled for maximum maneuverability. An hydraulically driven, computer controlled, reversible jaw assembly reciprocates the new pipe section relative to the exiting pipe line. A facer for trimming and squaring the pipe ends to be joined and a heater for melting the pipe ends for fusing are umbilically connected to the machine for on-board or remote operation. The computer, also on an umbilical, enables the operator to operate the machine in a normal mode in which the operator manually controls the facing, soaking and fusing processes or an automatic mode in which the fusing process is automatically controlled by the computer. The computer also allows the operator to choose a data logging mode in which the operating pressure, heater temperature and time data are recorded to provide a history for each joint made by the machine.
