Abstract: In a process for the preparation of microcapsules based on a melamine-formaldehyde resin, in which the microcapsules are obtained by condensing a melamine-formaldehyde precondensate, its C1-C4-alkyl ethers, or mixtures thereof, in water in which the material forming the capsule core is dispersed, at a pH of from 3 to 6.5 and at from 20 DEG  to 100 DEG  C., the improvement that the water contains a homopolymer or copolymer which possesses sulfonic acid groups but is devoid of phenyl or sulfophenyl groups and has a K value of from 100 to 170 or a viscosity of from 200 to 5,000 mPa.s (shearing gradient 489 s-1; 20% strength solution at 25 DEG  C.), and that the melamine-formaldehyde precondensate is added continuously, or in portions, in step with the rate of condensation. The process gives individual capsules which are highly impermeable. The capsules are exceptionally useful for the production of pressure-sensitive recording materials.

Filed: 1981-10-23
Abstract: L'invention se rapporte à la détection en temps réel de signal voisé et à la mesure de la fréquence de mélodie correspondante dans un signal de parole. Le procédé utilise un ensemble de données caractéristiques du signal de parole, fournies par des circuits de traitement (10, 20, 30): des mesures des intervalles de temps entre passages à zéro et des mesures de l'énergie dans les alternances de ce signal. La procédure de test mise en oeuvre par un microprocesseur (40) retient les alternances dont les énergies dépassent des seuils caractérisant les débuts de période de mélodie. Ces seuils sont prédéterminés pour les deux premières sommes successives retenues, puis dépendent des valeurs d'énergie des alternances précédentes retenues différemment selon que le caractère voisé du signal est acquis ou non. Des tests complémentaires sont mis en oeuvre pour minimiser les erreurs de détection. Application, notamment, au traitement des signaux de parole pour les vocodeurs.

Abstract: A tubular housing (1, 2) contains an electroacoustic transducer capsule (3) at one end. Adjoining this, a ring which is composed of segments (11-14) is located in the tube (1). Some (11, 13) of the segments are equipped with signalling and/or control devices (17-21) which protrude through openings (16, 22) in the tube jacket. The central angle of these segments (11, 13) is smaller than 180 DEG  by so much that they can be individually successively introduced into the housing (1) in parallel with the tube axis (30). When these segments (11, 13) have the correct position in the housing (1), the other segments (12, 14) are inserted between them (11, 13). The areas of abutment (31/32, 33/34, 35/36, 37/38), at which the segments abut one another, extend as wedge areas so that the ring composed of the segments (11-14) in the interior of the tube is driven apart and pressed against the inside wall of the tube. <IMAGE>

Abstract: A fire sensor system that can discriminate between a hydrocarbon fire and the effects of a penetration flash has four channels. A first channel of the system detects electromagnetic radiation in a spectral band of relatively long wavelength and a second channel detects electromagnetic radiation in a spectral band of relatively short wavelength. A third channel compares the relative intensity of the radiation detected by the first two channels and will generate a control signal if the ratio of intensities deviates substantially from unity. This third channel control signal, when generated, will be delayed by by a first predetermined period of time, and then will trigger an output signal if the first two channels still detect predetermined levels of radiation. The first predetermined delay period is set to be long enough to allow a substantial amount of the radiation of a flash subside. 
     The sensor system also has a fourth channel that monitors the intensity of the relatively long-wavelength radiation detected by the first channel. If the long-wavelength component increases beyond a predetermined value during a second predetermined time period that begins a third predetermined time period after the third channel control signal is generated, then the output signal will be triggered. The output signal, when generated, can be used to trigger an electro-mechanical suppressant release mechanism. 
     In another form of the four channel sensor system, the third channel generates its control signal only when the difference between the intensities of the radiation detected by the first and second channels exceeds a predetermined level.
