Abstract: The invention relates to a method for determining electric voltage u(.tau.) and/or electric current i(.tau.) of an RF signal in the time domain in a calibration plane (14) on an electrical conductor, wherein by means of at least one directional coupler (18) having two outputs (20, 22) and one signal input (19) a first component of a first RF signal that runs from the signal input (19) in the direction of the calibration plane (14), and a second component of a second RF signal that runs from the calibration plane (14) in the direction of the signal input (19) is decoupled.  In a first step, for a two-port error of the directional coupler (18) the error terms e00, e01, e10, and e11 e00, are determined as a function of a frequency f and then in a second step the signal values v1(.tau.) and v2(.tau.) are transformed, through a first mathematical operation, into the frequency domain as wave quantities V1(f) and V2(f), and absolute wave quantities a1 and b1 in the frequency domain in the calibration plane (14) are calculated from the wave quantities V1(f) and V2(f) by means of the error terms e00, e01, e10 and e11.

Title: One trip drill and casing scrape method and apparatus
Inventor: HERN GREGORY L
IPC: E21B37/02
Filed: 2014-06-26
Granted: 2019-09-24
Abstract: A drilling assembly is tripped in a cased hole to make more open hole. The assembly features retracted scrapers and a closed circulation sub so that the drilling can commence with string pressure delivered to bit nozzles due to the circulation sub being in a closed position. When drilling is done and the bit is to be removed, an object lands on a seat on a sleeve that acts as a piston to break scraper retainers for casing scraping deployment and to open the circulation port. A bypass opens around the seated ball when the sleeve shifts to allow flow around the seated ball for circulation while scraping. Drilling and casing scraping are accomplished in a single trip.

Abstract: Systems and methods are provided for determining a presence of an electronic message recipient based on an attribute of the electronic message, such as the content and/or context of the electronic message. The systems and methods can include acquiring, at a server, an electronic message from a sender, and determining an attribute of the electronic message. Based on the determined attribute, the server assigns an urgency level to the electronic message, which corresponds to a response time period. The server then monitors the recipient's device for a response to the electronic message, and to collect monitoring data about activity performed by the recipient on the device, or the environment surrounding the device. If the recipient does not respond within the response time period the server informs the sender a presence status of the recipient based on the monitoring data.

Abstract: Methods of reducing emissions levels during steady-state conditions are disclosed for use with a dry scrubber desulfurization system. A dry calcium hydroxide powder is injected into the gas flowpath and watered in the spray dryer absorber. The resulting slurry is then deposited on the filter bags in the baghouse. This can be done at lower temperatures than the spray dryer absorber would otherwise be operable, enabling desulfurization to occur earlier in the combustion process, particularly during startup of a cold boiler at ambient temperature. The operation of the boiler can also be backed up, made up, trimmed, or augmented depending on various operating scenarios.
