Patent EP-0427349-B1 (EP)
Inventor: BESEMER ARIE CORNELIS
IPC: C08B37/00
Filed: 1990-11-08
Granted: 1995-07-12
Abstract: A method for the preparation of polydicarboxysaccharides is provided wherein polysaccharides, such as starch and starch derivatives, are oxidised in the presence of hypobromite and/or hypoiodite and a low oxidising agent concentration is maintained during the oxidation reaction. The low concentration of oxidising agent can be maintained by adding the oxidising agent during the oxidation reaction. The hypobromite or hypoiodite is preferably formed in the reaction medium by oxidation of a catalytic amount of bromide or iodide, either by addition of hypochlorite or by passing an electric current. The product obtained by the method has good calcium and magnesium binding properties and is biodegradable, and thus it is very suitable for use as a builder in detergent compositions.

Abstract: A transponder (20) includes a receiver (22,28) for receiving a radio interrogation signal. The transponder also includes a phase locked loop decoder (28,38,42,46,40,45,134,132) for deriving a reference signal from the received interrogation signal, and radio transmitter means (138,68,72) for transmitting a transponder reply signal. The phase locked loop has an output (136) which feeds the AC reference signal to the transmitter. The transmitter includes a frequency doubler ( 138) which generates a transmitter radio frequency at double the frequency of the reference signal. The transmitter radio frequency is therefore control led by the radio frequency of the interrogation signal. The phase locked loop includes a divide-by-N counter (38), where N is a predetermined integer parameter. The parameter N determines the derivation of the reference signal frequency from the interrogation signal frequency. <IMAGE>

Abstract: On élimine le flou le long des bordures situées entre des régions ayant des caractéristiques de couleur différente dans des images en couleurs interpolées en utilisant une technique de traitement du signal qui segmente le canal entièrement échantillonné en une pluralité de régions d'image contigües de caractéristiques d'image respectivement différentes. Le système de segmentation est tel que, dans une région donnée, les valeurs du signal totalement échantillonnées sont associées à une caractéristique d'image commune. Une démarcation entre les régions adjacentes apparaît lorsque le système de segmentation a déduit la présence d'une bordure entre les emplacements sous-échantillonnés et a attribué des valeurs de signal aux emplacements successifs d'échantillonnage du canal entièrement échantillonné sur les côtés opposés de la bordure suivant les différentes caractéristiques d'image. Lorsque l'image a été segmentée, dans chaque région, les valeurs du signal pour les emplacements non échantillonnés du canal sous-échantillonné sont interpolées suivant une relation prédéterminée entre les valeurs du signal entièrement échantillonnées et sous-échantillonnées à un emplacement d'échantillonnage de cette région où chacune des valeurs du signal entièrement échantillonnées et sous-échantillonnées a été produite. En outre, on peut utiliser plus d'un système de segmentation. Dans ce cas, la performance du traitement de l'image de chaque processus de segmentation est évaluée. Les valeurs d'interpolation basées sur chaque processus de segmentation sont alors combinées pour donner une moyenne mesurée.

Abstract: When transmitting television signals with a 4:3 picture format for reception on a standard receiver and additional information, which may consist of additional lateral picture portions produced in the transmitter, for a 16:9 picture format for reception on a receiver which decodes this picture format, the additional information in a PAL signal is modulated to the colour information present in the PAL signal in such a manner that spectral spaces of the colour information (U, V) are doubly occupied. Cross-talk from the recognizable picture content (ghost image) is prevented by additional scrambling of the additional information. Parts (32, 33, 34) of the PAL decoder in the 16:9 receiver can be used advantageously at the same time to demodulate the additional signals.

Abstract: Lorsque l'auditeur d'un disque compact souhaite écouter un morceau de musique déterminé enregistré sur un disque compact, il doit attendre, pendant ledit temps d'accès, que le dispositif de balayage ait retrouvé le morceau de musique voulu et puisse commencer à le reproduire. Afin de réduire considérablement le temps d'accès dans un appareil d'enregistrement et/ou de reproduction au moyen d'un support d'enregistrement sur lequel les données sont subdivisées en groupes, les premières données n de chaque groupe sont premièrement stockées dans une mémoire (S), une fois que le support d'enregistrement (CD) a été inséré dans l'appareil. Lorsque l'appareil doit lire les données d'un groupe déterminé, il lit premièrement les données correspondant à ce groupe stockées dans la mémoire (S). Entretemps, le dispositif de balayage (A) de l'appareil a suffisamment de temps pour chercher le groupe. Lorsque le dispositif de balayage (A) a retrouvé le groupe et que le flux de données en provenance de la mémoire (S) est synchronisé avec celui en provenance du dispositif de balayage (A), l'appareil lit les données fournies par le dispositif de balayage (A). Le temps d'accès est ainsi réduit presque à zéro. L'invention s'applique à des lecteurs de disques compacts, de disques vidéo, de disques DRAW et à des appareils magnéto-optiques.
