Abstract: Remote control of power devices is described e.g. electric bulbs of lighting installations, by use of any remote control transmitter, primarily designed for an audio-video equipment. An infrared signal transmission method is used and in order to control a power receiver the signal derived from an infrared transmitter is used with discretionary ways of modulation. The signal is reproduced in the shape of a string of impulses (logical "zero", logical "one") and its duration is proportional to the duration of a signal excitation source of a guiding transmitter. 
     The circuitry, is characterized by an impulse-forming circuit (Ufl) connected to an infrared sensor (CP) and to input and delay counter (UZWOC) and furthermore, to a control signal forming system (UTSS). Signal forming circuitry (UTSS) through the intermediate circuit (UP) is connected to phase shift circuitry (UPF) and to a further sensor (S).

IPC: H03H11/04

Abstract: Based on the insight that the damping of a tunable filter is both related to its quality factor as to its passband gain, an inventive tuning system is proposed which tunes the quality factor of such a filter to a desired quality factor value by tuning the passband gain of the filter to a desired gain value. 
     Such a tuning system is particularly useful in the field of OTA-C filters and consists of first (P1) and second (P2) tuning paths including such a tunable filter (BIQUAD) and fixed gain amplifiers (B-OTA1, B-OTA2). The gain of the latter amplifiers corresponds to the desired gain values. The tuning system further includes matching means (MM) for equalizing the gains in both tuning paths (P1, P2) by generating a quality factor tuning signal (VTQ) which is applied both to the tunable filter (BIQUAD) and to a replica thereof used as master filter in a data processing path. 
     This matching means (MM) includes current rectifiers (C-REC1, C-REC2) implemented so as to use little hardware.

IPC: D21C7/00
Filed: 1992-06-09
Abstract: A conventional continuous digester is modified to effect alkali extraction of lignin after washing. After washing (17) at the bottom of the digester (11), the chips are reduced to fibers and then subjected to alkali extraction. Reduction of fibers takes place by mechanically acting on the chips with a rotating element (32, 35), and/or by causing the chips to mechanically break up by flowing through a high speed, turbulent zone (30) for a short period of time. The extraction zone is provided by an upright conduit (26) within the digester vessel, concentric with it, and having an open bottom (27) spaced above the closed bottom (22) of the digester vessel, and above the rotating element. The diameter of the lowermost portion of the upright conduit is significantly less than the diameter of the main body of the upright conduit. During alkali extraction (44), the fibers are maintained under the same pressure as in the digester, at a temperature of greater than about 100°C, and in an alkaline environment (normally just with alkali remaining from digesting). After alkali extraction the pulp is cooled (with 54) and then passed through a blow valve (50) adjacent the top (12) of the digester.

Abstract: Non-carcinogenic asphalts and asphalt blending stocks are produced from reduced hydrocarbon feedstocks. Such non-carcinogenic products are produced by establishing a functional relationship between mutagenicity index and a physical property correlative of hydrocarbon type for the asphalt or asphalt blending stock and determining a critical physical property level which, when achieved, results in a product having a mutagenicity index of less than about 1.0. Process conditions are established so that a product stream achieving the desired physical property level can be produced. Non-carcinogenic asphalts and asphalt blending stocks are then processed utilizing the conditions so established.

Title: Reglage automatique de la sensibilite pour stimulateurs cardiaques
Inventor: NICHOLS LUCY
IPC: A61N1/37
Filed: 1992-06-29
Abstract: L'invention concerne un stimulateur cardiaque capable de régler automatiquement la sensibilité de son amplificateur de détection par rapport aux signaux cardiaques électriques. Dans un mode de réalisation, un stimulateur cardiaque possédant un capteur de pression, placé à l'extrémité distale du fil de régulation/détection, compte le nombre de phénomènes dus à la pression et de phénomènes électriques qui se produisent lors d'une période d'autosensibilité. Si le nombre de phénomènes électriques dépasse le nombre de phénomènes dus à la pression au-delà d'une marge prédéterminée, le seuil de sensibilité de l'amplificateur de détection diminue. Dans un autre mode de réalisation, le stimulateur cardiaque maintient une moyenne glissante des tensions de crête des phénomènes électriques détectés sur une période marquée, prédéterminée. Périodiquement, le stimulateur cardiaque calcule le taux de la moyenne glissante des tensions de crête par rapport à une valeur de marge de détection préprogrammée, et règle le seuil de sensibilité de l'amplificateur de détection d'après ce calcul. En basant le réglage du seuil de sensibilité de l'amplificateur de détection sur une moyenne élevée des valeurs de détection de crête, les effets de variation cycle à cycle dans les valeurs détectées sont minimisés. Toujours, dans un autre mode de réalisation de l'invention, un capteur de pression seul est utilisé pour détecter les phénomènes cardiaques naturels.
