Patent CA-2338517-C (CA)
Inventor: NORTON DOUGLAS A
IPC: E21B47/12
Filed: 1999-07-22
Granted: 2006-05-16
Abstract: A fiber optic cable includes a core and a surrounding protective layer. The core includes an inner tube having one or more optical fibers contained therein, and the surrounding protective layer includes an outer tube received over the inner tube, and a layer of buffer material positioned between the outer tube and the inner tube. The buffer material maintains the inner tube generally centrally located within the outer tube and providing a mechanical link between the inner tube and the outer tube to prevent relative movement therebetween. The inner tube may be coated with a low hydrogen permeability material to minimize the entrance of hydrogen into the inner tube.      The low hydrogen permeability material may be coated with a protective layer of hard, scratch resistant material to protect the integrity of the low hydrogen permeability material. The area in the inner tube not occupied by the optical fibers may be filled with a filler material, the filler material being selected to have a sufficient viscosity to resist the shear forces applied to it as a result of the weight of the optical fibers within the tube while allowing movement of the optical fibers within the tube during spooling, deployment and handling of the cable to thereby prevent damage and microbending of the optical fibers. The filling material may be impregnated with a hydrogen absorbing/scavenging material to remove any excess hydrogen within the inner tube. The optical fibers have an excess length with respect to the inner tube, and the cable may include an outer jacket of a high temperature, protective material to protect the cable during handling and installation.

Abstract: La présente invention concerne un système de communication comprenant trois ressources de communication : un bloc d'accès de type conflit d'accès (112), un bloc d'accès sans conflit d'accès (114) et un deuxième bloc d'accès sans conflit appelé bloc réservé (110).  Chaque fois qu'une unité éloignée (104) doit transférer un bloc de données vers une station pivot (100), elle envoie ce bloc via le bloc d'accès de type conflit (112).  L'unité éloignée (104) envoie également un message de notification correspondant via le bloc réservé (110).  Si la station pivot (100) reçoit le message de notification mais pas le bloc de données, elle envoie un message de réponse à l'unité éloignée (104) dans lequel elle désigne une ressource dans le bloc d'accès sans conflit (114).  L'unité éloignée (104) envoie alors le bloc de donnée via la ressource désignée.

Abstract: A linearized traveling wave tube amplifier with average power limiter i s disclosed. The device includes an average power limiter for the purpose of preventing a TWT from operating at output powers higher than the required operating point . The device includes a detector for dynamically producing a detector signal proportional to an average power of an input signal and substantially independent from a peak power of the input signal and an attenuator in communication with the detector and the amplifier for dynamically attenuating the input signal according to the detector signal. T he limiter allows the TWTs to be optimized for performance at the required operating point resulting in higher efficiency, and eliminates the need to size the amplifie r for a power level any larger than the required operating point which reduces the cost an d complexity of the system. The limiter protects the TWT while not degrading the linear performance of the TWT by limiting the average power while allowing peak powers of short duration to pass with low loss.

Abstract: A storage and shipping system for glyphosate herbicide is provided, comprising a container having a capacity of about 0.1 to about 100,000 liters or more, substantially filled with an aqueous solution of glyphosate, predominantly in the form of one or a mixture of the potassium and monoethanolammonium salts thereof, the solution having a glyphosate acid equivalent concentration of at least about 30 percent by weight. The storage and shipping system, by virtue of the relatively high specific gravity of the glyphosate salt solution, holds a greater weight of glyphosate than a system comprising an identical container substantially filled with an aqueous solution of the isopropylammonium salt of glyphosate at the same glyphosate concentration by weight. Alternatively, the container of the storage and shipping system can be smaller than that of a container holding the same weight of glyphosate in the form of the isopropylammonium salt. Further, a larger number of such smaller containers can be shipped in a given enclosed volume, thereby enabling the shipment of a larger weight of glyphosate in a single consignment.

Title: Method and configuring a user interface for controlling a controlled device based upon a device class
Inventor: MCGRANE WILLIAM B
IPC: H04N5/44
Filed: 2000-06-05
Granted: 2007-04-10
Abstract: Electronic devices (16, 17) can be controlled by a control unit (11), which in turn is responsive to infrared commands (33) received from a remote (12) utilized by an operator. The remote has a touch-panel display (49), on which images can be displayed. The images are part of a user interface created by a program (86) running in a personal computer (13). An operator enters into the computer an identification of the devices (16, 17) which are to be controlled, and the computer then takes predefined images and automatically customizes them for these devices. Some of the images have a size which is less than the overall size of the display, so that when one of these images is displayed, a portion of at least one other image will also be visible. For a controlled device which does not recognize each of a discrete power on, discrete power off and power toggle command, the computer automatically effects configuration so as to provide all three functions using a subset of commands which the controlled device actually does recognize.

Abstract: Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.

Sur l'extérieur des couches extérieures de renforcement de traction (7, 8), on peut appliqué une couche (11) pouvant être facilement pénétrée par le milieu extérieur et protégeant la couche de renforcement de traction contre des influences mécaniques. Grâce à ce tuyau, on garantit que le renforcement de pression est en mesure d'absorber des forces issues aussi bien de la pression extérieure que de la pression intérieure.
