Abstract: The invention pertains to enzymatic liquid detergent compositions in which the enzymes comprise a mixture of lipolytic enzymes and proteolytic enzymes. The storage stability of lipolytic enzymes in these proteolytic enzymes containing liquid detergent compositions is enhanced therein by the inclusion of a lower aliphatic alcohol such as ethanol and a salt of a lower carboxylic acid such as sodium formate and by providing for a detergent-surfactant system therein which predominantly consists of a nonionic detergent. 
     The lipases are fungal lipases ex  Humicola lanuginosa  or  Thermomyces lanuginosus.  The proteolytic enzymes are preferably of the subtilisin type.

Abstract: The invention relates to a process and device for synchronising terminals which communicate via a transmission chain which does not supply any time reference. According to the invention the transmitting terminal transmits codes N and P, the first of which represents a master frequency Fo for an independent clock network, and the second a transmission frequency Fe. At the receiving terminal these codes N and P are compared to codes R and X, one of which represents the master frequency Fo of the clock network and the other a frequency Fr. The frequency Fr is then modified depending on the comparison of the codes, so that Fr = Fe. The invention is applicable to asynchronous transmission systems. <IMAGE>

IPC: H03M1/12
Filed: 1989-08-02
Abstract: The invention relates to a method and an arrangement intended for radio communication systems and effective in digitalizing and subsequently proces­sing numerically arbitrary radio signals. The signals are represented by compo­site (complex) vectors which have been subjected to disturbances in the system, such that information in the signals has been lost. This information is restored in its entirety when practising the present invention. For the purpose of solving this problem, the inventive digitalizing arrangement includes a multistage logarithmic amplifier chain (A) in which each stage is connected to a separate detector (D), the output signals of which are added in an adder. The adder output signals are then transmitted to a first A/D-converter (AD1) for digitalizing and converting the amplitude components of the signal. At the same time, the undetected signal from the saturated output stage in the amplifier chain is transmitted to a second A/D-converter for digitalizing and converting the phase components of the signal. The digital values obtained on the outputs of the AD-converters (AD1, AD2) are applied to different inputs of a digital signal processor (MP) for numerical processing of the pairwise received digital values in a manner such as to restore the complete vector characteristic of the signal.

Filed: 1988-11-14
Abstract: Un filtre de rétrodiffusion "chirp" (10) compare un signal reçu (RSIG) à un signal de référence relatif à un signal transmis (TSIG) et élimine du RSIG la composante de fréquence qui est égale à TSIG en fréquence. Cette composante de fréquence extraite correspond à la fréquence du rayonnement de rétrodiffusion de l'émetteur. Le filtre de l'invention ajoute un décalage de fréquence (fn) au RSIG et au TSIG dans les mélangeurs (12 et 14) avant de soustraire l'un de l'autre dans le mélangeur (22). Ainsi, des composantes de fréquence égales dans RSIG et dans TSIG, telles que la composante de fréquence du rayonnement de rétrodiffusion de RSIG, seront égales à fn. Les fréquences résultant de cette soustraction passent ensuite par un filtre à coupe-bande (24) qui est centré sur fn et qui fait passer toutes les composantes de fréquence à l'exception de fn. La sortie du filtre coupe-bande n'a donc plus de composantes de fréquence associées à la composante de fréquence de rétrodiffusion. La perte de la référence de phase RSIG due à la référence de phase entre les enveloppes de modulaton RSIG et TSIG détruites pendant le procédé de filtration de rétrodiffusion est compensée en ajoutant TSIG à la composante de fréquence de différence filtrée, rétablissant ainsi la relation de phase des composantes de fréquence RSIG originales moins la composante de fréquence de rétrodiffusion.
