Title: Method and system for determining position of mobile radio terminals
Inventor: FISCHER SVEN
IPC: G01S11/08
Filed: 1998-11-20
Abstract: A method and apparatus are disclosed for determining more accurately, in a radio environment with time dispersion, the distance between a radio receiver and radio transmitter, by special processing of received radio signals that have been transmitted repeatedly from the same radio transmitter and are possibly subject to multipath propagation. The Time of Arrival (TOA) of the received radio signals is repeatedly estimated using channel power profiles. A TOA value near the minimum occurring TOA is selected wherein each estimated TOA is derived from incoherent integration of a randomly chosen number of the received bursts having the same known bit sequence, in order to eliminate the influence of noise.

Abstract: On mélange un composant d'agent d'encapsulation liquide renfermant un agent d'encapsulation sensible et actif, tel qu'un micro-organisme vivant ou une enzyme dissoute ou dispersée dans un plastifiant liquide, avec un matériau matrice plastifiable. Le matériau matrice peut être plastifié au moyen du plastifiant liquide, et l'encapsulation de l'agent d'encapsulation actif se fait à basse température et dans des conditions de mélange à faible cisaillement. Le composant actif est encapsulé et/ou inclus dans le composant ou le matériau matrice plastifiable au cours d'un procédé continu de production de particules discrètes solides. La teneur en liquide du composant de l'agent d'encapsulation liquide constitue la totalité ou presque du plastifiant liquide nécessaire à la plastification du composant matrice pour obtenir un mélange ou une pâte que l'on peut façonner, extruder, ou découper. Il n'est pas nécessaire d'éliminer le plastifiant liquide avant l'extrusion pour ajuster la viscosité du mélange afin de le rendre plus facile à façonner. La libération d'un composant actif par la matrice peut être retardée ou contrôlée dans le temps de manière que le composant actif soit libéré au moment et à l'emplacement où l'on souhaite qu'il remplisse ses fonctions. Ce procédé permet de produire en continu des particules discrètes solides à libération contrôlée, qui renferment un composant encapsulé ou inclus, tel qu'un composant pharmaceutiquement, biologiquement ou nutritionnellement actif, sensible à la chaleur ou s'oxydant facilement, sans destruction sensible du matériau matrice ou de l'agent d'encapsulation.

Title: Method of producing an elastomer blend that is similar to thermoplastic elastomers, on the basis of reclaimed rubber or waste rubber
Inventor: SCHOLZ HENRIK
IPC: C08J11/00
Filed: 2000-05-17
Abstract: The invention relates to a method of producing an elastomer blend that is similar to thermoplastic elastomers on the basis of reclaimed rubber or waste rubber. According to this method, reclaimed rubber or waste rubber that has been reduced to powdered rubber is processed to compounds by subjecting it to a melt-mining process in a mixer together with a thermoplastic material and at least one stabilizer in different weight percentages. The aim of the invention is to improve this method so that a mixture that consists of two phases that are usually incompatible, namely the powdered rubber and a thermoplastic material, is processed to a blend that is characterized by the properties of thermoplastic elastomers. Said blend should have a constant quality, should be reproducible and repeatedly recyclable and the method should allow the conversion in a melt-mining process over a relatively short mixing period by choosing suitable materials for the thermoplastic constituent and other additives. To this end, at least one polypropylene copolymer or a mixture thereof with at least one polypropylene type is melted in the mixer and powdered rubber, at least part of which has been pre-swelled in a radical donor, is dosed to the melt. The powdered rubber is dispersed in the plastic matrix by applying high shearing strains and admixing radical-forming agents in order to couple the two phases that consist of the powdered rubber and the polypropylene copolymer or a mixture thereof in accordance with defined mixing parameters. The dynamic stabilization process is carried out at a temperature of the mixture that is above the melt temperature of the polypropylene copolymer or the mixture thereof but below the decomposition temperature of the powdered rubber and over a mixing period that allows the reaction of the radical former.
