Filed: 1994-06-21
Abstract: Le dépôt du peptide bêta-amyloïde neurotoxique est un processus pathologique qui se déroule dans le cerveau de patients atteints de la maladie d'Alzheimer. L'invention se rapporte à des procédés qui consistent à traiter un patient avec un composé thérapeutique qui agit en bloquant la formation de la bêta-amyloïde issue de la protéine précurseur d'amyloïde (APP). Nous avons identifié la protéase aspartique cathepsine D comme étant une protéase responsable de la transformation amyloïdogène de l'APP. L'invention se rapporte également à des composés non toxiques qui bloquent à la fois l'activité in vitro de la cathepsine D humaine, et la libération de la béta-amyloïde par les cellules humaines. Ces inhibiteurs de la protéase aspartique sont donc utiles comme agents thérapeutiques pour traiter la maladie d'Alzheimer en bloquant l'accumulation pathologique de bêta-amyloïde.

Title: Spaced sleeving in use with pipe coupling
Inventor: GEOFFROI LOUIS EMIL GERARD
IPC: F16L13/08
Filed: 1996-05-07
Abstract: A ring to be employed with couplings and such fittings as are already in use in plumbing installations.     The ring, having protruding lugs for spacing is, in use, inserted over the end of a pipe which is to be fitted into a coupling.

Abstract: A satellite communication system has at least one satellite (1) with an antenna that generates a moving beam pattern on the surface of the earth. The beam pattern (3) is comprised of a plurality of sub-beams (4). A method of this invention determines an attitude correction signal for the satellite by the steps of:  (a)  providing at least one reference transmitter (10) at a known location on the surface of the earth;  (b) transmitting at least one signal from the at least reference transmitter into at least one of the sub-beams;  (c)  receiving the at least one signal with the satellite antenna and transponding the received at least one signal to a ground station (8). A next step of the method (d) receives the transponded at least one signal with the ground station;  (e)  determines a gain of the received at least one signal; (f) compares the determined gain  to  a  gain  expected  to  be  received  based  on  a predetermined knowledge of a spatial variation in gain of the satellite antenna; and (g) and determines a difference between the determined gain and the expected gain to derive a correction signal indicative of an attitude error of the satellite.  The method  further  includes  the  steps  of transmitting the correction signal to the satellite; and correcting the attitude of the satellite in accordance with the correction signal. For the case where the correction signal has a value that is a function of the yaw error angle of the satellite, the method further includes the steps  of  transmitting  the  correction  signal  to  the satellite; and correcting the attitude of the satellite in accordance with the correction signal by rotating the satellite about the yaw axis so as to reduce a magnitude of the yaw error angle.

IPC: G10L25/93
Filed: 1996-10-22
Abstract: A speech encoding method and apparatus in which an input speech signal is divided in terms of blocks or frames as encoding units and encoded in terms of the encoding units, in which explosive and fricative consonants can be impeccably reproduced, while there is no risk of foreign sound being generated at a transient portion between voiced (V) and unvoiced (UV) portions, so that the speech with high clarity devoid of "stuffed" feeling may be produced. The encoding apparatus includes a first encoding unit 110 for finding residuals of linear predictive coding (LPC) of an input speech signal for performing harmonic coding and a second encoding unit 120 encoding the input speech signal by waveform coding. The first encoding unit 110 and the second encoding unit 120 are used for encoding a voiced (V) portion and an unvoiced (UV) portion of the input signal, respectively. The constitution of a code excited linear prediction (CELP) encoding employing vector quantization by a closed loop search of an optimum vector using an analysis-by-synthesis method is used for the second encoding unit 120.
