Abstract: A method for producing a leno or cross weaving texture in which, alternatingly with successive weft insertions, a first warp thread, also said "crossing-­thread" (4), gets crossed with at least one second warp thread on the one side and on the other one side relatively to said at least one second warp thread, also said "stationary-thread" (7), with said crossing-thread being moved both transversely and perpendicularly to the weaving plane (C), and said stationary-thread being only moved perpendicularly to the weaving plane. 
     The method comprises the steps of: 
■ providing a line segment (10) connecting, upstream a beating reed (12), two planes perpendicular to the weaving plane and laying: the one plane, on one side of the stationary thread (7), and the other one plane on the other side of the stationary thread, with both of said planes being parallel to said stationary thread; 
■ then inclining said line segment (10) so as to cause said line segment to cross the weaving plane alternatively on the one side and on the other side of said stationary thread (7), 
■ shifting the crossing-thread (4) in a vertical direction   relatively to the weaving plane and above the line segment (10) which is being inclined, so that the crossing-thread, by coming to rest against the inclined line segment at least when said inclined line segment crosses the weaving plane on one of the two half-planes into which said weaving plane is subdivided by the stationary-thread (7), is caused to slide towards this same half-plane, so as to get crossed with the stationary-thread, and produce the leno or cross weaving texture.

Title: Démodulation synchrone à quart de cycle pour un capteur de vitesse angulaire et d'accélération linéaire basé sur l'effet de Coriolis
Inventor: MACGUGAN DOUGLAS CAMPBELL
IPC: G01C19/5776
Filed: 1988-11-15
Abstract: Un appareil et un procédé permettent de déterminer la vitesse angulaire de rotation et l'accélération linéaire d'un corps par rapport à trois axes orthogonaux (x, y, z). Trois paires d'accéléromètres (10, 12; 14, 16; and 18, 20) sont agencées avec leurs axes sensibles antiparallèles les uns aux autres, et chaque paire est animée d'un mouvement de vibration alternatif le long d'un des axes orthogonaux. On traite les signaux produits par les accéléromètres pour déterminer Svit et Svel pour chacun des axes de vitesse en fonction de la somme et des différences des signaux produits par chacun des accéléromètres. Un microprocesseur (82) utilise la valeur de Svit pour chaque axe afin de produire un signal égal à la variation incrémentielle de vélocité (DELTAV) pour chaque axe. On utilise ensuite cette variation incrémentielle de vélocité conjointement avec les erreurs estimées provenant des précédentes portions fractionnelles de la période de tremblement pour chaque paire d'accéléromètres afin de calculer la vitesse de rotation du corps autour de chacun des axes en fonction des valeurs de Svit. Dans un autre aspect de l'invention, la variation incrémentielle de vélocité et les variations incrémentielles de position angulaire (DELTA)p) peuvent être calculées sous forme d'une moyenne cumulée des précédentes portions fractionnelles de la fréquence de tremblement.

Abstract: On cultive des plantes, par exemple des légumes, dans un milieu de culture inactif, y compris l'aquaculture, dans lequel on alimente les plantes avec un liquide aqueux contenant un agent régulateur de croissance ou de santé tel que par exemple de l'azote. La culture se fait par division d'une zone de culture en une zone de référence (10) et une zone de production (11) ayant sensiblement les mêmes conditions de culture, et par alimentation des plantes se trouvant dans la zone de référence (10) avec un premier liquide aqueux dans lequel ledit agent est présent dans un concentration déterminée empiriquement. Ledit agent est amené au premier liquide de manière continue ou intermittente dans des quantités telles que la concentration de l'agent dans ledit premier liquide est sensiblement maintenue au niveau empiriquement déterminé. On alimente les plantes situées dans la zone de production (11) avec un second liquide aqueux comportant une seconde concentration fixe de préférence inférieure dudit agent, lequel agent est alimenté audit second liquide de manière continue ou intermittente, dans des quantités régulées, par exemple proportionnellement par rapport aux quantités de l'agent ajouté au premier liquide. Ainsi il devient possible de réguler la teneur des plantes en agent régulateur de croissance ou de santé de manière, par exemple, à réduire la teneur en nitrate sans entraîner une éventuelle réduction de la production ou détérioration de la qualité.

Abstract: Formulations pour prégonfler et dégrader des polymères fonctionnalisés, comme des polycarbonates, en une, deux ou trois étapes. La surface attaquée peut ensuite être revêtue avec du nickel ou du cuivre chimique, l'adhésion des métaux de revêtement obtenus étant satisfaisante. Les agents gonflants rendent les molécules polymères à la surface et à proximité de la surface du polymère facilement accessibles à l'agent de dégradation. Un agent de dégradation dégrade les molécules polymères. Au besoin, un agent de dissolution augmente la miscibilité de l'agent de dégradation et de l'agent gonflant. Un agent mouillant augmente l'efficacité de l'agent de dégradation. Dans le procédé en une seule étape, des parties polymères sont trempées dans une solution contenant au moins un agent gonflant et au moins un agent de dégradation. Dans le procédé en deux étapes, les parties polymères sont d'abord traitées avec une solution d'agent gonflant puis attaquées avec une solution d'agent de dégradation. Dans le procédé en trois étapes, les parties polymères sont d'abord rendues microrugueuses avec une solution d'agent gonflant, puis attaquées avec une solution d'acides inorganiques avant d'être trempées dans un bain caustique de manière à rendre leur surface mouillable.

Abstract: An apparatus and method for simulating the forces acting on the steering wheel or other control device of a vehicle. The apparatus uses an electrical motor coupled to a steering wheel in the preferred embodiment. The electrical motor is driven by a computer running software which received data regarding the real world forces which would be acting upon a real steering wheel in a car under similar conditions. A software driver coupled to a position-sensing transducer on the steering wheel calculates the steering wheel position and velocity and sends this data to a model process not forming part of the invention. The model process then calculates the conditions affecting the simulated vehicle and outputs data reflecting the real world forces which would affect the steering wheel of the actual car under similar conditions. This data is used to calculate a force number which in turn drives a driver amplifier and motor combination coupled to the steering wheel of the simulated vehicle to simulate the forces that the driver of a real vehicle would feel.
