Patent EP-0277173-A1 (EP)
Inventor: ROSEN HAROLD A
IPC: H01Q25/00
Filed: 1987-07-23
Abstract: Un système de communications par satellite utilise des systèmes auxiliaires séparés de radio-diffusion et de communications à deux voies point par point se servant de la même bande de fréquences attribuée. Lesdits systèmes auxiliaires de radio-diffusion et de communications point par point utilisent un système d'antennes de satellite intégré comprenant un réflecteur commun (12). Le système auxiliaire de communications point par point permet d'obtenir une capacité de communications accrue grâce à la réutilisation de la bande de fréquences attribuée sur plusieurs zones contiguës (32, 34, 36, 38) couvrant la surface de la terre devant être desservie. Des terminaux à petites ouvertures disposés dans les zones sont desservis par plusieurs faisceaux de transmission en éventail à liaison descendante et à gain élevé (29) orientés dans la direction est-ouest par adresse de fréquences. Un réseau spécial formant des faisceaux de transmission (98) fournit en coopération avec une antenne de réseau (20) la fonction d'adresse de fréquences des zones multiples. Le satellite (10) utilise un réseau matriciel d'interconnexions de filtres (90) pour la connexion des terminaux de terre des différentes zones de façon à permettre la réutilisation multiple de la totalité de la bande des fréquences attribuées. Un pool unique d'émetteurs à l'état solide permet d'attribuer aux utilisateurs désavantagés par la pluie une puissance plus élevée que la normale à un coût minimal. Les produits d'intermodulation des émetteurs sont géographiquement dispersés.

Abstract: A straw chopper possesses an essentially horizontal driven rotor shaft (8) which is mounted in a trough-shaped housing and to which a plurality of radially projecting implements (12) serving for comminution are fastened with end edges so inclined obliquely relative to the shaft axis that these form a milling and/or cutting enveloping cylinder. An upper feed funnel is connected to the housing, preferably by means of batons arranged at a distance from the enveloping cylinder over part of its circumference and concentrically relative to this and fastened to the housing, with ejection orifices (20) provided on the side regions of the housing, and with devices conveying the material (36) to the ejection orifices (20) axially relative to the rotor shaft (8). In order to provide a straw chopper of this type of increased output and spreading width, the comminuting implements (12) themselves are designed as axially conveying devices which transport the material (36) from the middle region of the enveloping cylinder to the lateral ejection orifices (20).

Abstract: A latex agglutination immunoassay method for determining an analyte in a blood sample in which the pH of the reaction mixture is maintained at about 8.5 or greater in order to overcome nonspecific agglutination of latex particles by hemoglobin present in the sample. The method is particularly applicable to the determination of glycated hemoglobin, e.g., Hb A1c. In another embodiment, native hemoglobin (Ao) can be determined based on its ability to cause agglutination of latex particles suspended in an aqueous solution having a pH of about 8 or below.

Abstract: Système (1) répondant à des entrées (2) en parallèle avec un estimateur d'état (4). Le système de commande (6) fournit les entrées (2) en réponse à des entrées d'état ordonnées (14) et à des entrées de l'estimateur d'état. Un vecteur (f) de perturbations externes intervient sur le système (1) de sorte que les valeurs observées des variables d'état sont différentes des valeurs estimées. Les valeurs estimées et mesurées sont comparées (8) pour donner un signal d'erreur (9). Les valeurs d'erreur sont introduites dans un correcteur d'état ordonné (11) qui calcule l'erreur qu'aurait la variable d'état ordonné dans l'état stable, et l'applique dans le sens opposé pour augmenter l'état ordonné d'entrée (14). S'il faut corriger plus d'une variable d'état, la correction est directement appliquée aux entrées de commande par utilisation du correcteur multi-état, dans lequel les erreurs d'état stable sont utilisées pour trouver les entrées de commandes qui provoqueraient les erreurs, et ensuite une correction est appliquée aux entrées de commande.

Abstract: Solid, water-free dispersions of Raney catalysts in fusible organic embedding agents can be obtained by first introducing a Raney catalyst slurry into a vacuum mixer blanketed by an inert gas, admixing the embedding agent, removing the major part of the water at temperatures below the melting point of the embedding agent and removing the remaining water above the melting point of the embedding agent in vacuo while maintaining the mixing motion. After the water removal, the vacuum is broken by admitting inert gas and, if appropriate, the product is formed into mouldings of low surface area.

Abstract: Apparatus for avoiding stuck drilling equipment during drilling of a well bore over depth intervals where such equipment has stick in similar wells in a geological province includes data storage means for recording a multiplicity of well drilling variable quantities measured substantially simultaneously at a known depth in each of a multiplicity of wells. Such multiplicity of wells includes those in which drilling equipment has stuck and a multiplicity of similar wells where the drill string did not stick. Such data forms the input to multivariate statistical analysis means for calculating for all variables in all wells of each class the maximum separation of said classes from each other. The centroids of all well vectors representing each of the multiplicity of wells in each such classes are then recorded either numerically or by plotting. A currently drilling well relative to said classes is then established by means for calculating its well vector relative to the well classes. Such calculating means sums the products of the coefficient of each variable for the complete group of wells times the current value of each variable in the drilling well. The well vector is then recorded to plot or indicate which variable may be modified within allowable values to change the plotted location of the drilling well toward the centroid or mean of the wells that did not stick the drill string.   
     A method of determining whether a stuck drill string can be freed is provided by calculating the centroids of two groups of stuck wells using the same procedure for multivariate analysis of a multiplicity of drilling parameters to identify whether or not a stuck well is in a group of wells which could not be unstuck.
