Title: Method and arrangement for generating surface-scanning patterns for finding discontinuities in materials
Inventor: TOERNBLOM BENGT HJALMAR
IPC: G01N27/82
Filed: 1987-10-29
Abstract: The invention relates to a method and an arrangement for finding discontinuities in materials by means of a sensor which is sensitive to the discontinuities in question. According to the invention, the material 1, for example in the form of a web, is scanned by at least two sensors G1, G2 which are made to move, during scanning, over the material web in at least two circular paths RB1, RB2 or the like in a plane essentially parallel to the plane of the material or part thereof, and the centres of rotation P1, P2 of the at least two sensors are arranged so that their centre distance C is smaller than the sum of the radii of rotation or the like of the same sensors, that is to say R1 + R2 > C. In this manner, the sensors will scan the material surface in question so that the surface-scanning patterns formed by the sensors and their movements are adequately fine-meshed and orientated in order that any discontinuities can be found, for example detected and indicated, on the whole irrespective of the orientation and position of the discontinuities on/in the material. <IMAGE>

Filed: 1992-08-24
Abstract: An apparatus for compensating the phase rotation in the feedback loop of a cartesian feedback power amplifier in a final transmitter stage for quadrature modulation of the complex difference signal between a complex input signal and the corresponding complex feedback signal with a complex modulation signal for forming a modulated real valued first signal and for quadrature modulation of the output signal from the power amplifier with a complex demodulation signal for forming the complex feedback signal. The phase shift between the first signal and the second signal and between the quadrature component of the first signal and the second signal is detected for determining the phase rotation of the feedback loop. Furthermore, the phase rotation of the complex modulation signal can be changed with a compensating phase rotation defined by the determined phase rotation.
