Patent EP-0443936-A1 (EP)
Inventor: SEEMAN BRONISLAW
IPC: E21B47/00
Filed: 1991-02-19
Abstract: A method and apparatus for evaluating the cement (10) in a borehole where a determined concentration of substance such as boron or a boron compound is initially mixed with the cement. After the casing (12) has been cemented, logging measurements are performed in the borehole by means of a sonde (14) including a fast neutron source (24) and a plurality of gamma ray detectors (25a, 25d) distributed all around the sonde. The gamma ray spectrum detected by each detector is analyzed in order to obtain the number of neutron capture gamma rays due to thermal neutron interactions with boron. The information obtained in this way is directly related to the quantity of boron present around the well, and is used for determining the thickness of cement surrounding the casing.

Abstract: Cet étage amplificateur comprend un tube hyperfréquence dans lequel un faisceau d'électrons (3) interagit avec une onde hyperfréquence de fréquence variable comprise dans une plage utile donnée, la vitesse des électrons du faisceau étant déterminée par une tension de cathode (V<sub>k</sub>) appliquée au tube et l'onde hyperfréquence se propageant dans une structure à retard (4) lui imposant une vitesse de phase proche de la vitesse du faisceau d'électrons.Selon l'invention, la tension de cathode est une tension variable, régulée en fonction de ladite fréquence, cette tension variant avec la fréquence pour modifier la vitesse des électrons du faisceau de manière que, pour toute fréquence de ladite plage de fréquences utile, la vitesse correspondante de ces électrons reste essentiellement, mais non exactement, identique à la vitesse de phase de l'onde hyperfréquence.De la sorte, on compense la dispersivité en fréquence de la structure à retard et on maintient ainsi essentiellement constante la puissance délivrée en sortie par le tube.

Abstract: L'invention concerne un châssis de civière destiné à supporter une civière dans un véhicule, par exemple une ambulance. Le châssis de civière comprend une table de support montée sur ressort et pouvant être levée et abaissée. Cette table de support est reliée au sol par l'intermédiaire d'un parallélogramme de support et d'un élément de base, et ladite table peut être extraite ou bien introduite alors que sa liaison avec le sol est maintenue. Ce dispositif facilite la manipulation de la civière par le personnel accompagnant car ladite civière peut déjà être placée sur le châssis à l'extérieur de l'ambulance alors que le patient est allongé sur elle. En outre, l'invention présente l'avantage suivant: l'élément de base est le seul élément en contact avec le sol, de sorte que les accélérations verticales qui se produisent pendant le transport sont transmises avec moins d'intensité à la table de support sur laquelle se trouve la civière.

Title: Bidirectional light steering apparatus.
Inventor: REZNICHENKO YAKOV
IPC: A61B3/12
Filed: 1991-05-09
Abstract: An optical steering assembly includes first and second steering elements, such as orthogonally-oriented glavanometer mirrors, scanners or acousto-optical cells, for redirecting light in both forward and return optical paths without crosstalk or mixing. Input light traveling in the first direction is directed from the first side of the first element to the first side of the second element, undergoing two orthogonal steering deflections to a redirected output path. Return light along the same or a closely adjacent path is directed at the second side of one element, where an optical relay system tranlates it to the second side of the other element. The return light thus strikes the opposite sides of the same elements as the input light, and undergoes corresponding steering corrections while maintaining complete beam separation. The assembly is especially useful in instruments where low light levels, scan distortion, or crosstalk would otherwise limit performance. A two dimensional fundus tracker employs one such assembly as an objective steering system for all illumination, and two further assemblies for positioning tracking beams directed into the objective steering system.

Abstract: An applicator wheel 40 and guide system are provided in order to accurately align and position web material 34, either as discrete lengths 12 or as a continuous strip, to articles or a continuous web. Specifically, the guide system includes a lateral edge guide disc 124 rotatable with the applicator wheel 40 which exhibits an edge guide surface at a first point along the periphery of the wheel applicator 40 to precisely laterally align the web material 34 and which moves radially inward from the surface of the applicator wheel 40 at an application point so as not to obstruct the application of the web material 34 to the articles or continuous web moved at a constant rate thereby. Moreover, the guide system includes the provision of an air bar 66 for forming a loop in the supplied strip of web material 34 prior to handling by the wheel applicator 40. The air bar eliminates roller inertia and guarantees consistent lengths of discrete lengths of web material 34 to be applied to articles or a web when used on a wobbler arm. The edge guide and the air bar 66 increase the accuracy with which web material 34 can be successfully applied to articles or a web with regard to lateral and length alignment, respectively.

Abstract: An article conveying system, of the type having a conveying surface (12) defined by the uppermost ones of a plurality of slats (14) interconnected in an endless web for displacing articles laterally with respect to the conveying surface and including a diverter shoe (16) movably mounted to each slat (14), includes a system of parallel tracks (28a-f) and diverting gates (20a-f) to independently selectively move one or more diverter shoes (16) laterally while maintaining lengthwise alignment of the selected shoes (16) in order to displace an article without rotation of the article. A control senses both the position of articles and the position of shoes (16) in order to determine the relative spacing between shoes (16) and articles. This allows the control to determine whether a shoe (16) assigned to an article interferes with another article to accommodate article spacing of less than one shoe. Articles may be displaced using only one or two shoes by determining that the shoe is properly positioned with respect to the article. A divert control module maintains a dynamic accumulated article length for the accumulation section of a take-off conveyor based on article-length data received from a central sort controller, spur take-off speed and the time from the most recent divert in order to determine whether an article may be diverted to the associated spur.
