Title: Methode de mesure de la permeabilite a l'humidite et dispositif correspondant
Inventor: MIZOBE KUNITAKA
IPC: G01N5/04
Filed: 1999-07-26
Abstract: Cette méthode de mesure de la perméabilité à l'humidité consiste à peser une éprouvette dans une pièce à température et humidité constantes et ce, sans la sortir de cette pièce ni la mettre en contact avec l'atmosphère, l'évaluation du poids de l'éprouvette n'étant pas perturbée par des phénomènes vibratoires. Cette méthode permet d'estimer objectivement les résultats de la pesée par détection de l'état de la vapeur d'eau pénétrant un échantillon et par mesure de la température de l'eau stockée. Le dispositif de mesure de la perméabilité à l'humidité comprend une balance électronique (7) placée sur un support amortisseur (6) installé dans la pièce à température et humidité constantes (P). On mesure avec précision, à l'aide de la balance électronique, le poids de l'éprouvette (T) contenant l'échantillon (2) sur une coupelle de mesure (1) contenant de l'eau (W) et les résultats de cette mesure sont convertis en valeur de perméabilité à l'humidité. La coupelle de mesure (1), qui comprend un corps principal (10) et un anneau de retenue (11), renferme des thermocouples (40), immergés dans l'eau et disposés sur la paroi périphérique du corps, ainsi qu'un capteur de température et d'humidité (41), placé de manière à occuper l'espace (15) existant entre la surface de l'eau et l'échantillon.

Filed: 2000-03-10
Abstract: The invention concerns signalling methods in cellular telecommunication systems, especially in so called third generation cellular systems, such as the UMTS system. In the inventive method the network checks, if the mobile station is in or is about to enter into such a state, in which the mobile station needs a c-RNTI, and if that is the case, the c-RNTI is indicated to the mobile station. Preferably, the indication is effected by attaching the c-RNTI  identifier to a message, which causes the change of the mobile station to the state, in which the mobile station needs the c-RNTI identifier.

Abstract: An annular-shaped, expansion type clamping band has laterally overlapping ends, each having a skewed surface, the skewed surfaces slidably engaging one another. The ends are further provided with elongated guide slots for receiving a threaded bolt.  A threaded nut threadly engaging the bolt, when tightened, moves the overlapping ends toward a longitudinal central axis of the band whereby the band expands to exert an outward radial force against an interior surface of a gasket to provide a liquid-tight fit between the gasket and an opening having a surface engaging an outer periphery of the gasket. The band may be a one-piece or two-or-three-piece assembly and may be formed of an suitable metallic or plastic material. The threaded member is slidable along the aforesaid guide slots enabling the bolts to be self centered. The nut and bolt assembly, in one embodiment is designed to require only one tightening tool.

Patent CA-2375452-A1 (CA)
Inventor: KRIZ JEFFREY J
IPC: G01S5/12
Filed: 2000-06-08
Abstract: Multiple pulses of narrow band signals of varying frequency are detected by multiple spaced apart receivers such that average time difference of arrivals of the signals from an item to be located are determined. The average time differences are used to calculate a position of the item to be located with a desired accuracy, such as within one meter in one embodiment. One of multiple receivers or rangers initiates a location process by transmitting a sync pulse. The sync pulse is received by a scout and other rangers. The scout is a small robot which acts as a transponder, sending out its own narrow band return pulse in response to the sync pulse. Each ranger then determines a difference in time between the sync pulse it receives and the return pulse generated by the scout. The location process is then repeated again at different selected narrow band frequencies, and an average of the difference in time at each ranger is determined. Each ranger is networked together via a standard wireless network, and also obtains position information via standard GPS methods. An iterative calculation of the location of the scout is used to improve an estimated position solution. Time difference of arrival between two rangers is expressed as an equation with three unknown variables, x, y and z, which define a position of the scout in three dimensional space. The locus of a point that satisfies this equation is hyperbolic. The iterative calculation uses at least squares approach to improve the estimated position to within a required tolerance.

Title: Method and apparatus using antennas to measure electrical anisotropy
Inventor: GIANZERO STANLEY C
IPC: E21B49/00
Filed: 2002-06-27
Abstract: A logging tool is disclosed having transmitting and receiving antennas to measure formation anisotropy. The antennas may preferably be combinations of toroidal, horizontal electric dipole, and horizontal magnetic dipole antennas. In one embodiment, the tool: (a) induces a current flow in the tubing or drill string traversing the formation in a borehole; (b) measures a signal difference between two receiver antennas on the drill string; (c) determines an apparent conductivity of the formation from the resistive component of the signal difference; and (d) uses the apparent conductivity to calculate an anisotropy coefficient with a knowledge of the horizontal conductivity. The tool may further determine a second apparent conductivity of the formation from the reactive component of the signal difference, and use both apparent conductivities to calculate the anisotropy coefficient and the horizontal conductivity. The vertical conductivity can also be determined from these two calculated values in the usual manner.
