Patent CA-2392882-A1 (CA)
Inventor: STEINERT WOLFGANG
IPC: H04L27/38
Filed: 2002-07-10
Abstract: Known burst signals exchanged between senders and receivers comprise either one syncronisation block followed by a data block or several equidistant synchronisation blocks separated by data blocks, with a synchronisation block including predefined synchronisation symbols and with a data block including data symbols. By adapting senders and receivers in such a way that said synchronisation blocks are being located non-equidistantly, preferably with a centre of gravity of synchronisation symbols mainly corresponding with a centre of said burst signal, an improved synchronisation can be reached.      Thereto, senders and receivers comprise locators for locating said non-equidistant synchronisation blocks, with said receivers preferably further comprising determinators for determining phases of synchronisation blocks, and synchronisers for synchronising detectors/demodulators in dependence of neighbouring as well as non-neighbouring non-equidistant synchronisation blocks, and processor systems for calculating frequencies in dependence of locations and/or phases. Said processor systems preferably comprise estimators for in dependence estimating main frequencies.

Abstract: The present invention relates to a process for producing a fabric-elastomer composite that, when transfer or film coated, is preferable for use as an artificial leather substrate. The inventive procedure involves (a) producing  an elastomer composition of at least four ingredients (an anionically- stabilized waterborne polymer dispersion, an acid-generating chemical, a clo ud- point surfactant, and a foam-stabilizing surfactant); (b) incorporating sufficient gas into the liquid mixture to generate a spreadable foam; (c) applying the foam onto a porous textile substrate; (d) heating said foamed fabric until the elastomer coagulates over the fabric substrate; and (e) drying the resultant composite without destroying the coagulated structure. The resultant composite obtains a suppleness that is similar to that of leather and a surface that is suitable for transfer coating to produce artificial leather. The composite may be utilized as upholstery fabric in furniture or in automobiles, apparel, and the like. The particular composite s produced are also contemplated within this invention.
