Abstract: Process for dewatering a volume of sludge, comprising in particular sludge which is difficult to dewater. Flexible separating strings are arranged in the volume of sludge, which strings divide the volume of sludge into self-draining volume regions. The volume of sludge is thickened with uncontrolled flexible deformation of the separating strings arranged therein by formation of folds and the like with a dewatering pressure of over 10 bar to give a dewatered sludge cake. The sludge cake is then broken up by stretching the separating strings. A sludge dewatering press for carrying out the process is also described.

Abstract: According to a method of performing ultrasonic flaw detection, a pulse signal is output to an ultrasonic probe attached through an ultrasonic wave propagation medium to an object to be tested, a reflected wave of the ultrasonic wave incident on the object is received by the ultrasonic probe to obtain an echo signal. The carrier frequency of the pulse signal is set so that the peak frequency of the echo signal becomes a predetermined frequency, and then the cycle count of the pulse signal is set so that the frequency bandwidth of the echo signal becomes a predetermined bandwidth. A defect present in the object is detected in accordance with the echo signal output from the ultrasonic probe. 
     According to an apparatus for performing ultrasonic flaw detection, an ultrasonic transmitter transmits a pulse signal having a designated carrier frequency and a designated cycle count to an ultrasonic probe. An ultrasonic receiver receives the echo signal output from the ultrasonic probe. The peak frequency and the frequency bandwidth of the echo signal received by the ultrasonic receiving unit are detected by a signal analysis unit. A transmission control unit designates the carrier frequency and the cycle count of the pulse signal output from the ultrasonic transmission unit so that the detected peak frequency and the detected frequency bandwidth become a flaw detection condition peak frequency and a flaw detection condition frequency bandwidth, respectively.

Abstract: A radio frequency coil for use in MR imaging applications includes a series of conducting segments (24) aligned with the longitudinal, static magnetic field of the MR magnet. A hybrid power splitter/combiner (32) feeds each axial segment with a phased signal to generate a transverse circularly polarized magnetic field. The power splitter/combiner (32) isolates the axial segments to reduce magnetic field distortions produced by capacitive coupling between the imaged object and the radio frequency coil. The axial segments are tuned to series resonance to further reduce capacitive coupling. A stepped shield design permits separation of the power splitter combiner from the axial segments without piercing the bore tube.
