摘要:
An apparatus operable is a hazardous area for controlling a choke assembly includes an air source, an air purge system in fluid communication with the air source, a remote operating panel receiving data from at least one remotely located wellbore sensor, a local operating panel in electronic communication with the remote operating panel, and an actuator coupled to the assembly to control pressure within the wellbore. The remote operating panel includes an airtight housing in fluid communication with the air purge system, wherein air from the air purge system is circulated through the housing, a plurality of operator controls for manually controlling operation of the pressure control assembly, and a display for visually displaying values of data received from the wellbore sensor. The local operating panel includes an airtight panel housing in fluid communication with the air purge system, wherein air from the air purge system is circulated through the panel housing, and a local operator controller having an operator interface for receiving operator instruction input into the local panel, and operable to receive operator instructions from the remote panel and transmit operator instructions. The actuator includes a motor in an explosion-proof housing coupled to the choke plate and operable to adjust the orifice through the choke plate, wherein the motor receives electronic communication of the operator instructions transmitted by the local operator controller, and a position indicator coupled to the choke plate for sensing the orifice opening and providing feedback of the choke plate position to the motor.

摘要:
A method for constructing a rich query from a selected semantic entity included in a page, the method comprising: receiving user input identifying a semantic entity for which contextual information is desired; identifying context information associated with the selected semantic entity; encoding a Uniform Resource Locator (URL) using the semantic entity an the identified context information; and transmitting the encoded URL to a search server.
摘要:
For electronic commerce, selected items are tracked in a database and are made available for purchase by interactions with a customer. The construction and maintenance of the database may be summarized by three general steps. The first general step in the construction of the electronic commerce site is the establishment of a link between a particular product and a particular program or program episode that features the product. The second general step is creating a database of the records or links that are established from the first general step. The third general step is establishing an interface with the customer, which may be accomplished through the internet. A preferable technique for generating product tracking information uses radio frequency identification (RFID) tags to dynamically track products located in the video frame.
摘要:
A method to inject a slurry into a subterranean formation includes measuring characteristic data from a well in communication with the subterranean formation, estimating downhole properties of the slurry using the measured characteristic data, measuring surface properties of the slurry with a measurement apparatus, determining optimal surface properties for the slurry from the estimated downhole properties, comparing the measured surface properties with the determined optimal surface properties, modifying the slurry until the measured surface properties are within tolerance values of the determined optimal surface properties, and injecting the modified slurry into the subterranean formation through the well.

摘要:
The present invention is concerned with a monoclonal antibody or antigen-binding fragment of a monoclonal antibody produced by a hybridoma formed by fusion of cells from mouse myeloma cells and spleen cells wherein said monoclonal antibody or fragment thereof reacts with the carrier or transfer protein of a bacterial cell. The bacterial cell may be coryneform bacteria or bacteria of the genus Staphylococcus.
摘要:
A Soccer Goal Retainer includes a bar rotatably mounted in an enclosure. A clamp plate includes a lower member attachable to the bar. A vertical member extends at right angles from the lower member and an upper member extends from the vertical member generally at right angles. A lip extends generally at right angles from the upper member. With the vertical member generally positioned vertically, the lip, the upper member and vertical member are placed over the rear rail of a soccer goal and the clamp plate is secured to the bar. The clamp plate is released from the rear rail by loosening the clamp plate from the bar. The clamp plate and the bar are then rotated in a forward manner and downwardly into the enclosure. A cover is placed over the enclosure both when the clamp plate is in use and when it is being stored.
