Abstract: A combination fuel pressure regulator and fuel filter apparatus (17) for vehicle fuel systems has a fuel supply tank (11) with a fuel pump (13) therein for pumping fuel to a fuel supply rail (20) having fuel injectors (21) attached thereto. A fuel filter (25) is operably disposed between an inlet supply tube (16) and a fluid outlet tube (18) for filtering impurities from fuel passing therethrough. A valve (30,53,50) in fluid communication with the inlet supply tube (16) is provided with a regulator for causing flow to be short circuited back into the fuel supply tank (11) when the pressure in the fluid outlet (18) exceeds a predetermined level. The valve (30,53,50) is biased to a closed position and will remain closed as long as the pressure on the clean side of the filter (25) is below the predetermined pressure whereby all of the fuel in the inlet supply tube (16) will pass through the filter (25).

Title: Procedes et dispositif concernant la micropropagation
Inventor: MCFARLANE NIGEL JAMES BRUCE
IPC: A01H4/00
Filed: 1991-07-26
Abstract: Un procédé de localisation de la tige d'une plante pendant un processus de micropropagation comprend les étapes de génération d'un signal d'image au moyen d'une caméra vidéo représentant une image des plantes et le traitement du signal d'image pour localiser les parties de plantes qui possèdent des largeurs et des longueurs susceptibles de constituer des parties de tiges. On sélectionne alors les tiges en choisissant des parties de plantes remplissant les critères suivants: l'angle situé par rapport à la verticale du côté se rapprochant le plus de la verticale de la partie de plante est inférieur à un angle prédéterminé et on peut tracer une trajectoire descendante continue depuis la base de la plante jusqu'à la surface du matériau dans lequel pousse la plante, en traversant ce dernier. Un autre critère qu'on peut utiliser est que la partie de plante se termine à sa partie supérieure et à sa partie inférieure en une zone de matériau dont la dimension est supérieure à différents critères prédéterminés. Les signaux de localisation sont alors traités pour produire un signal de commande servant à commander à un effectueur d'extrémité robotique de se déplacer à l'emplacement désiré, de saisir la tige sélectionnée et d'enlever la plante ou la partie désirée de celle-ci, du milieu nutritif dans lequel elle pousse. On peut calculer des informations stéréo en observant la plante à partir de points légèrement différents.

Abstract: Coupleurs de fibres optiques comprenant une fibre centrale (18, 21) et un nombre sélectionnable de fibres environnantes (10, 20), avec un contact réciproque entre les fibres environnantes et la fibre centrale, formées de préférence de fibres initiales de diamètre identique. Selon une formule, avec entre trois et cinq fibres environnantes, la fibre centrale (18, 21) a un diamètre réduit, tandis qu'avec sept fibres environnantes ou plus, les diamètres des fibres environnantes sont réduits. On décrit des coupleurs avec une entrée et quatre, huit, douze, ou seize sorties égales, qui ont une réponse de longueur d'onde aplatie. Des organes servent à réduire le désaccord de phase nuisible, au niveau du rapport de couplage souhaité, par exemple, en accordant virtuellement les constantes de propagation de la fibre centrale et des fibres environnantes dans le coupleur fini. Les mesures prises pour accorder suffisamment les constantes de propagation consistent notamment à: raccourcir la région du coupleur réunie par fusion; à commencer avec des fibres ayant des constantes de propagation différentes sélectionnées de façon que les différences diminuent durant la fusion; à réunir les fibres par fusion jusqu'au stade où il n'y a virtuellement pas de vides interstitiels dans la masse de fibres réunies par fusion; et à entourer les fibres environnantes (10, 20) d'une substance transparente ayant l'effet d'un revêtement. Pour obtenir ce dernier effet, un tube (11) ou des tiges optiques transparentes assemblées autour des fibres environnantes sont appliqués par fusion, ou la substance transparente est une substance moulable appliquée après la formation de la région du coupleur réunie par fusion.

Abstract: The invention relates to a support mattress, in particular for hospital beds, consisting of foam material with several layers of the same or different specific density and different compression hardness. In this case, the lying surface (1) of the upper layer (2) is divided by longitudinal and transverse grooves {incisions} (3 and 4) into squares (10) of defined size depending on the loading of the body, and the lower surface of the first layer (2) has an undulating structure (12) which extends into a corresponding undulating structure (13) of the upper surface of a lower layer (11) and interacts therewith flexibly. The surface area of the squares (10) in the region of the head, back and buttocks zones of the lying surface (1) is greater than in the other regions in proportion to the surface loading by these parts of the body. The surface area of the squares (10) decreases starting from the central region up to the longitudinal edge region of the lying surface (1) and is larger once again in the outermost longitudinal edge region. The cross-sections of the grooves (3) bounding the squares are of rectangular and/or pear-shaped and/or droplet-shaped construction. <IMAGE>

A plurality of terminal pins (43) are received in the passages and project from the insulator block for insertion into holes in a printed circuit board and for solder connection to circuit traces on the circuit board. The terminal pins are interference-fit in the passages in the insulator block to allow the block to be slid off the pins after soldering to the printed circuit board. The area (E) of the interference-fit between the terminal pins and the pin-receiving passages is less than the thickness of the insulator block to reduce the amount of force required to slide the block off of the pins while affording the block to be of a substantial thickness. The pin-receiving passages are provided with chamfered mouths to facilitate insertion of terminal pins into the passages. A flange (46) projects outwardly from the top (48) of the insulator block to facilitate gripping the block and sliding the block off the terminal pins.
