Title: Method for verifying the location of an array of detectors
Inventor: ZINN NOEL DONALD
IPC: G01S5/18
Filed: 1998-05-20
Granted: 2000-11-07
Abstract: A high-order, polynomial regression curve is fitted to a global set of first-arrival pick times as a function of the nominal ranges between a plurality of acoustic sources having known geodetic coordinates and a plurality of acoustic detectors whose coordinates are imperfectly known.  The polynomial is applied to the pick times to provide pick time distances with the vertical velocity gradient removed.  The known source coordinates, the nominal detector coordinates and the pick time distances are combined to provide a quadratic surface to provide a common data block containing the coefficients for modeling the lateral velocity gradient. Using the so-determined coefficients, the imperfectly-known detector positions are iteratively updated using the Helmert blocking technique.

In accordance with the when electromagnetic wave is supplied to the first micro-strip antenna, the first micro-strip antenna resonates and radiates electromagnetic waves to atmosphere therearound. The second micro-strip antenna is electromagnetically coupled to the first micro-strip antenna through the opening formed at the ground plate. Asa result, the second micro-strip antenna resonates to the first micro-strip antenna to thereby radiate electromagnetic waves to atmosphere similarly to the first micro-strip antenna. Hence, the antenna is able to have bi-directional or non-directional characteristic. In addition, since electric power is supplied only to the first micro-strip antenna, it is no longer necessary for the antenna to include a three-dimensional power distributor unlike a conventional antenna, ensuring thatthe antenna can be fabricated in a smaller size.

Abstract: Une unité de commande du système de distribution des produits chimiques s'utilise conjointement avec un mécanisme pour distribuer des produits chimiques spécifiés, et avec un dispositif transmettant des signaux de déclenchement au système de commande en vue de demander la distribution de ces produits chimiques. L'unité de commande reçoit et accumule des séquences des signaux de déclenchement transmis. Chaque séquence de signaux de déclenchement est précédée et suivie d'un intervalle de durée prédéfinie pendant lequel aucun signal de déclenchement n'est reçu. Au moins certains des signaux de déclenchement dans certaines des séquences ne sont pas reçus simultanément. De même, le nombre de demandes distinctes d'apport de produits chimiques, pouvant être communiquées à l'aide des signaux de déclenchement accumulés, dépasse le nombre de signaux de déclenchement distincts. L'unité de commande met en correspondance un premier sous-ensemble des séquences de signaux de déclenchement accumulées avec des demandes d'apport de produits chimiques, dont chacune requiert une certaine quantité d'un produit chimique correspondant. L'unité de commande permet la distribution des produits chimiques conformément aux demandes d'apport de ces derniers. Un deuxième sous-ensemble des séquences de signaux de déclenchement accumulées est mis en correspondance avec des codes de classification de lavage, dont chacun identifie un type de charge de lavage à laver à l'aide des produits chimiques distribués. Le nombre de codes distincts de classification de lavage pouvant être communiqué à l'aide des signaux de déclenchement accumulés dépasse le nombre des signaux de déclenchement distincts. Lorsque le système de commande met en oeuvre un dispositif d'apport agissant en fonction de la classification, la demande d'apport de produits chimiques correspondant à chaque séquence de signaux de déclenchement reçue est déterminée sur la base du type de charge de lavage en cours et de la séquence accumulée de signaux de déclenchement.

Title: Method and apparatus for drying iron ore pellets
Inventor: CHAPMAN DANIEL R
IPC: F26B21/00
Filed: 2000-08-18
Granted: 2004-12-14
Abstract: In the present method of drying iron ore pellets, e.g., magnetite pellets, moisture-containing iron ore pellets are formed into a bed comprising a multiplicity of the pellets. A current of drying gas is forced upwardly through the bed of pellets to at least partially dry some of the pellets with air jets simultaneously directing air downwardly onto the top surface of the bed. Radiant heat reflectors are placed above the bed to reflect heat back onto the pellets. Air is forced between the reflectors and onto the bed, especially below a firebrick wall located between the end of the updraft drying zone and the downdraft drying zone. Water is applied to the hot pellets to produce steam as well as water vapor which is added to a current of air to produce a stream of hot, humid air that is passed through the bed to improve pellet characteristics and recover waste heat. Air supplied at a selected point is cut off responsive to the presence of a blow hole in the bed so as to improve drying efficiency and improve uniformity of drying.
