Patent EP-0279975-A1 (EP)
Inventor: GARZONETTI GARY AUGUST
IPC: B01D29/60
Filed: 1987-09-09
Abstract: A method of controlling the pulsing of a granular medium filter (1) is provided bases on determination of the rise rate of the liquid level in the filter tank (3) above the filtration medium (1). A pulse system is activated whereby a pulse, in which sub-fluidizing flows of a fluid are directed upwardly through the filter medium (1) from an array of orifices (7), is initiated whenever the determined liquid level rise rate attains a predetermined value. The pulse flows dislodge solids from the upper surface (11) of the bed (1) and cause a portion of the solids to be stored within the bed itself at particular loci, thus decreasing the resistance of the bed and reducing the liquid level rise rate. The frequency of backwashing needed is accordingly optimized over a wide range of solids load, liquid load and other factors affecting the filtration. Backwashing may be initiated after a predetermined number of pulses, after a preset filtration time has elapsed, or when the level of liquid in the tank (3) reaches a preset high value (25).

Abstract: Un circuit compensateur à oscillateur à cristal (13) possède un cristal oscillateur (12) excité par un circuit à oscillateur piézoélectrique (19), la fréquence (f) pouvant être décalée dans certaines limites à l'aide d'une diode à capacité variable (14). La température du cristal est mesurée par un capteur de température (17) qui retransmet un signal de température par l'intermédiaire d'un convertisseur analogique/numérique (22) à un microprocesseur comportant un bus (24), un port d'entrée/sortie (15), une mémoire morte programmable PROM (16) et un circuit logique (18). Ce microprocesseur calcule, en fonction du signal de température compte tenu d'une régularité connue et de nombres caractéristiques, stockés dans la mémoire PROM, pour le cristal étudié, un signal de compensation de température, lequel est transmis par l'intermédiaire d'un convertisseur N/A (21) à la diode à capacité variable. Le signal de compensation de température (UK) présente une valeur telle que l'incidence qu'il produit sur la fréquence de l'oscillateur piézoélectrique compense exactement l'incidence sur la fréquence engendrée par la variation de température mesurée. Un tel circuit compensateur à oscillateur à cristal est bien moins onéreux et bien moins encombrant qu'un circuit correspondant classique de précision identique, qui exigeait des thermostats réglés avec une très grande précision. D'autres circuits compensateurs décrits servent à compenser les effets du vieillissement ou de l'accélération.

Abstract: While CVD (chemical vapor deposition) methods and enhanced CVD methods for the production of thin films have recently been attracting considerable interest, it has not hitherto been possible to deposit satisfactory carbon films by use of these techniques. The invention discloses a modification of the conventional CVD process for carbon deposition in accordance with which a halogen gas or a halogen compound gas is introduced into the carbon gas which is to be dissociated for deposition of carbon. By virtue of the introduction of the halogen or halogen compound, it has been found possible to form diamond or i-carbon films and moreover characteristics of the films, such as their optical transmissivity, electrical conductivity and hardness, can easily be controlled by controlling the halogen introduction conditions. CVD apparatuses for carrying out the process are also disclosed, and several applications of carbon thin films are disclosed.

Abstract: A connection point (20) giving ultimate access (36) to an integrated circuit is formed on an insulating layer (22) above a P- substrate (23). The latter is earthed via a P+ zone (32) and connection point (33). A hollow square (25) of N- material, containing a P+ zone (24) and surrounded by an inset N+ zone (26), is produced by doping under the point (20), the latter making contact (27) with the P+ area. The P+ and N+ zones are interconnected (30) at one point only. When a positive overvoltage occurs, an avalanche diode formed between the N+ zone (26) and the earthed substrate (23) breaks down. This turns on a transistor whose base is constituted by the N- square (25), the resulting emitter-collector current flowing between the associated P+ (24) and the P- (23) zones reducing the surge potential still further and dissipating its power.

Abstract: Un système thermophotovoltaïque (8) comprend une structure définissant un brûleur à flamme de diffusion ayant des orifices (18, 70) d'admission séparés mais adjacents de carburant et comburant, et une structure définissant une chambre de combustion (10) dans laquelle une structure émettrice est disposée pour exposer à la combustion les produits du brûleur. Les produits de combustion chauffent la structure émettrice (26) et provoquent l'émission d'un rayonnement distribué de manière spectrale. Une ou plusieurs cellules photoélectriques (40) sont disposées en relation de couplage optique par rapport à la structure émettrice (26) pour convertir l'énergie radiée par la structure émettrice (26) en énergie électrique, une proche correspondance entre le spectre de l'énergie photonique radiée par la structure émettrice et le seuil de production d'électrons du réseau (40) de cellules photoélectriques résultant en un rendement amélioré. Une portion (66) du courant de produit de combustion s'écoule de la chambre de combustion (10) au travers d'un récupérateur (54) pour chauffer le comburant arrivant, et une autre portion (64) du courant de produit de combustion s'écoule dans la chambre de combustion. Des améliorations de rendements significatives sont obtenues en préchauffant par récupération le comburant, et la réintroduction d'une partie des gaz d'échappement dans le mélange de combustion permet de réduire la température de la flamme en compromettant de manière minimale le gain de rendement obtenu par le préchauffage de comburant de sorte que les limites de stabilité thermique d'un ou de plusieurs composants du système ne sont pas dépassées.

Abstract: A method of controlling a motor for injection molding against overheating. The motor current is sampled at given intervals, and the square of each sampled value is multiplied by the corresponding sampling period. A number of products or values thus obtained during a cycle of injection are summed. This sum is divided by a value which is obtained by multiplying the square of the maximum current value by the ratio of heat dissipation at the continuous rated current to heat dissipation at the maximum current. If the period of a cycle of injection subtracted from the above resultant value is positive and the motor is somewhat overheated, then the motor is put at rest and set for a longer cycle of injection (S8 to S71).

Abstract: Une composition orale, qui est destinée à être dispersée dans un support aqueux essentiellement immédiatement avant son administration, contient une multiplicité de particules qui comprennent une substance active et qui sont combinées avec un ou plusieurs adjuvants de gélatinisation ou agents gonflants capables de former un milieu visqueux autour des particules dans un support aqueux, lesdites particules étant en outre pourvues d'une couche de surface de masquage lorsqu'elles sont dispersées dans le support aqueux. Cette surface sert à masquer la présence de surfaces inégales sur les particules et à empêcher les particules d'adhérer aux muqueuses de la bouche lors de l'ingestion de la composition, rendant ainsi plus aisée l'administration de doses importantes d'une substance active. La couche de surface de masquage présente de préférence une viscosité supérieure du milieu visqueux à proximité immédiate des particules par rapport à la viscosité du support aqueux qui les entoure. On prépare une telle composition prête à l'emploi en la mélangeant avec un support aqueux essentiellement immédiatement avant l'administration de la composition.
