Title: Method for the treatment of spent liquers in pulp production processes in the wood-processing industry
Inventor: KORHONEN OLLI
IPC: D21C11/00
Filed: 1989-10-24
Abstract: (57) ABSTRACT OF DISCLOSURE            The  invention  concerns a  method for the treatment of the spent liquors obtained from pulp production processes in the wood-processing industry, in which method the waste obtained from a chemical cooking process and that obtained from a me-chanical process are merged for joint treatment. The chemi-cal  process may be e.g. a sulphate process and the mechani-cal  process  e.g.  a chemi-thermomechanical process (CTMP), and  the invention presupposes that the facilities for these processes  are  located close by each other, suitably within the  same  industrial  complex. The essential feature of the invention  is  that  the spent liquor of the CTMP is used as wash  water  in counter-current washing of the pulp obtained from  the  chemical process. The spent liquor can be used to replace  part of the fresh water required for the washing of the  chemical  pulp, and the point at which the spent liquor is  added  to  the  process  in the washing department is so chosen  that  the  solids  content of the wash water at said point  has  risen  to  essentially  the  same level with the solids  content  in the spent liquor to be fed in. The waste liquors obtained from the chemical and mechanical processes, merged  as  provided by the invention, are conveyed from the washing  department into an evaporating plant and further to a  burning  station.  The cooking chemicals contained in the green  liquor  obtained as a combustion residue are regener-ated and used again.

Abstract: L'invention est constituée par une méthode et un appareil servant à déterminer la précision de la phase et de l'amplitude de signaux à modulation de phase continue. Un signal RF modulé produit par un émetteur subit un abaissement de sa fréquence jusqu'à une fréquence intermédiaire relativement basse et le signal résultant est filtré et échantillonné par un convertisseur analogique-numérique à fréquence d'échantillonnage élevée. Le signal numérique résultant de la conversion est traité par un processeur qui produit une fonction d'amplitude mesurée et une fonction de phase mesurée correspondant au signal RF modulé. Une fonction de phase idéale correspondant au signal RF modulé est calculée et synthétisée à partir des fonctions d'amplitude et de phase mesurées. Cette fonction de phase idéale est comparée à la fonction de phase mesurée afin de déterminer laquelle de ces fonctions doit être utilisée pour calculer les erreurs de phase et de fréquence du signal RF modulé.

Abstract: ABSTRACT OF THE DISCLOSURE In a parallel-mode adaptive transversal equalizer, P- and Q-channel data streams from A/D converters (1,5) are respectively passed through the tapped-delay lines of transversal filters (2,6), on the one hand, and are one-symbol delayed, on the other, by delay circuits (3,7,66,67) to produce (N-1) successively delayed P- and Q-channel data streams, which are respectively passed through the tapped delay lines of transversal filters (4; 63,8;64). In each transversal filter, symbols appearing at successive taps of the tapped-delay line are sampled and held for a duration of N symbols to produce first and second groups of stored symbols, the stored symbols of the first group being multiplied by first tap weights and summed, producing N first equalized outputs for each channel. The stored symbols of the second are multiplied by second tap weights and summed, producing N second equalized outputs for each channel. The first equalized outputs of each channel are respectively combined by adders (10-14,68,69) with the second equalized outputs of the other channel and multiplexed (14,15) into P- and Q-channel outputs. Correlations are detected by correlators (16-19, 70, 72) between data and error components of each of the P- and Q-channel outputs to control the first variable tap weights of associated tapped-delay lines, and correlations are detected by correlators (2-23, 71, 73) between data components of one of the P- and Q-channel outputs and error components of the other channel output to control the second variable tap weights of associated tapped-delay lines.

Title: Photon generator for micro-wave signals
Inventor: HORSLEY PETER B
IPC: H01J21/02
Filed: 1990-11-28
Abstract: ABSTRACT   When electric charges are vibrated back and forth in a conductor, the strongest component of the resulting magnetic field is at right angles to the axis of the vibration. In the state-of-the-art micro-wave technology, the strong component is not used. Instead, the projected beam of radiant energy is derived from reflected electric fields. The result is that the projected waves of energy are not coherent and tend to spread or fan-out over distance, which limits the signal strength that is available. In my invention, only a selected portion of the magnetic field is used and the electric field is not used except incidently. The projected beam of energy is accomplished by vibrating the charges in a radial pattern. The strong componentsof the resulting magnetic fields combine by vector addition. The combined fieldstake the shape of a toroid, and the projected beam is a train of toroidal waves with alternating polarity. This photon-like structure of fields is coherent and persistent. The desired configuration of the magnetic fields in the projected beam is accomplished by a circular planar array of radial conductors and a planar reflector adapted to return the counter-wave to re-inforce the projected wavefront. To provide the vibrating charges, an electric current is alternated through radial conductors at the carrier-wave frequency. Other means for oscillating electric charges in a radial mode can also be used, such as between shaped electrodes within vacuum tube, or with a radial pattern of capacitors.
