Patent SE-0002715-L (SE)
Inventor: LINDQVIST FREDRIK
IPC: H04B3/23
Filed: 2000-07-19
Abstract: An echo canceller reduces an echo signal produced when the transmitted signal leaks back into the receiver via a hybrid. The echo canceller estimates the echo signal from the transmitted signal, and then subtracting the estimated echo signal from the received signal. In practice, the echo path channel in a DMT-modem is much longer than the cyclic prefix, and therefore, the received echo signal will be subjected to both ISI (inter-symbol-interference) and ICI (inter-carrier-interference). A traditional echo canceller, designed for a xDSL-modem, uses either a time domain adaptive FIR-filter or a combined echo canceller implemented in both time and frequency domain. A matrix-based adaptive echo canceller is implemented in the frequency domain. Various example embodiments are disclosed.

Production of dry cellulose fibres consists of introducing wet pulp and air into a jet drier (20) to form separate cellulose fibres, and includes a predrying stage in which additive is introduced to reduce fibre knotting. The anti-knotting agent is selected from a group comprising a surfactant and mineral particles, and it is mixed mechanically with the pulp to produce a pulp in a foam state before it is fed into the drier. Alternatively, the wet pulp can be treated with a substance selected from the group comprising a reticulation agent and a water-repellent material. The aim of the treatment is to reduce the number of knots to below 5 per cent and preferably below 1.6 per cent. After drying, the fibres have a moisture content of less than 2 - 10 per cent by weight.

As shown, the excitation current i e  fed to the rotor of a synchronous machine 3 by a converter 1 is sensed and a corresponding signal is supplied to a controller 60 for comparison with a value set by the output of a dividing circuit 70. The divisor input of circuit 70 is connected to a terminal 47 of flux computer 5 which produces a signal proportional to the cosine of the rotor displacement angle #. The dividend input of circuit 70 receives the sum of a constant signal K representing noload magnetizing current, and the desired value I* B  of the stator current component parallel to the field. This arrangement ensures a constant airgap flux with varying rotor angle. Additional control may be provided by further signals from a flux controller 4 and a desired flux value #*.

Abstract: Release coatings are provided by including in a liquid monomer or prepolymer polymerizable by electromagnetic or ionizing radiation a waxy material of limited compatibility therein. Upon application of a film of such material by casting, coating or printing, a thin layer of the waxy material migrates to the surface to provide, after cure, the desired release properties. The thin surface layer of waxy material also tends to exclude oxygen from the film to permit radiant curing in air. Preferably the polymerizable liquid comprises acrylate monomers with or without unsaturated prepolymers co-polymerizable therewith dissolved therein. Novel prepolymers especially useful for providing release films and other radiation curable coatings are described, including the reaction product of polyamine containing polyamides with unsaturated polybasic carboxylic acids and particular reaction products of polyether triols with toluene diisocyanate, modified with unsaturated monomers. Also described is the inclusion in the polymerizable liquid of a dispersed substantially linear polymer as shrink control and re-inforcing agent.
