The circuit has a main amplifier path in which the main amplifier, a first variable attenuator and a first variable phase shifter are interposed, first and second delay line paths, a first power distributor for distributing an input signal to the main amplifier path and the first delay line path, an auxiliary amplifier path in which an auxiliary amplifier, a second variable attenuator and a second variable phase shifter are interposed, a second power distributor interconnecting the main amplifier path and the second delay line path, a first power combiner interconnecting the first delay line path and the auxiliary amplifier path, a second power combiner combining the signals from the second delay line path ant the auxiliary amplifier path to output, and a signal transmission path connecting between the branch ends of the second power distributor and the first power combiner. First and second pilot signals are coupled with the input signal and the signal transmitting the main amplifier path, respectively. The first variable attenuator and the first variable phase shifter are controlled in response to level and phase differences of the first pilot signal components at the first power combiner, respectively. Similarly, the second variable attenuator and the second variable phase shifter are controlled in response to level and phase differences of the second pilot signal components at the second power combiner, respectively.

Abstract: High-speed and high accuracy digital-to-analog (D/A) converters find many applications in signal processing. For wideband telecommunication systems, there is a strong demand on high-performance D/A converters. With the design of the present invention it is enabled to prevent distortions and intermodulations for high-speed and high-accuracy digital-to-analog (D/A) converters for telecommunication applications, where the requirements on distortion and intermodulation can be very stringent. By combining segmentation for MSBs and binary weighting for LSBs a high-performance digital-to-analog conversion architecture can be achieved, where a delay for the binary weighted LSBs is used to equalize a delay introduced by segmentation and where all bit switches (14) are clocked with a tree-like-clock distribution network (11). New floor plans for CMOS, BiCMOS and bipolar implementation are thus invented and circuits for CMOS bit switches and current sources are also disclosed.

Abstract: In a method and an apparatus for measuring a concentration of at least one dissolved chemical entity in a liquid medium, employing a counter electrode, a working electrode and a reference electrode immersed in the liquid medium, at least one measurement potential is applied to the working electrode relative to the reference electrode, corresponding to a measurement voltage during at least a part of a measurement period, thereby causing the dissolved chemical entity to participate in an electrochemical reaction at the working electrode, the chemical reaction resulting in a measurement evoked current. Compensation for potential drift at the reference electrode is achieved by comparing the measurement evoked current with a predetermined value, and decreasing or increasing the measurement voltage by an incremental value, in a negative or a positive incremental step, so that the measurement current approaches a predetermined value. After each increment, a new comparison is made and the next increment is determined dependent on that most recent comparison.

Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop. <IMAGE>

Title: Treatment method
Filed: 2011-03-07
Abstract: The invention provides a method for reducing the effects of biological contamination in a hydrocarbon-containing system into which aqueous fluid is injected, the method comprising the steps of: continuously adding a formulation comprising tris(hydroxymethyl) phosphine or a tetrakis (hydroxymethyl) phosphonium salt to the system for a time period of one day or more; monitoring the efficacy of the continuous treatment by an assessment of the extent to which there is any effect on the environment that is attributable to metabolic activity of active bacteria present in the system; and if required, optimising the continuous treatment to ensure that the treatment is having an effect on the metabolic activity of active bacteria present in the system; wherein the tris(hydroxymethyl) phosphine or tetrakis (hydroxymethyl) phosphonium salt is added at a concentration of from 1 to 30ppm, based on the total volume of aqueous fluid added to the system, and wherein the formulation is added to the system at a stage to minimise incompatibility with other any other chemicals that are added to the aqueous fluid. The treatment disrupts the metabolic activity of active bacteria in the hydrocarbon-containing system and can prevent or reduce detrimental effects arising from the presence of active bacteria in the system, such as biological reservoir souring and microbially-induced corrosion.
