Granted: 2004-03-23
Abstract: A wireless communication system uses transmitted data signals to monitor and control redundant modulator hardware. A modulator unit signature identifying the modulator unit currently transmitting data is emebedded into each data frame carried by the transmission signal. Each modulator unit (42 or 44) can then independently monitor the transmission signal to determine which modulator is currently transmitting data. Each modulator unit (42 or 44) then monitors the transmission signal in case the modulator unit actively generating the transmission signal fails. In a failure situation, the active modulator unit disconnects itself from the transmission circuitry while the backup modulator unit independently connects to the transmission circuitry to begin active transmission.

Title: Method of catalyst deactivation in continuous polyethylene terephthalate production
Inventor: NICHOLS CARL S
IPC: C08K5/524
Filed: 1997-05-20
Granted: 2005-04-12
Abstract: A continuous process for producing polyethylene terephthalate polyester from terephthalic acid and ethylene glycol uses a stabilizer, preferably containing phosphorous, to produce a high quality polyethylene terephthalate polyester which is relatively free of the acetaldehyde and discoloration which are associated with the post-polymerization activity of a polymerization catalyst. The stabilizer is preferably added at or after the end of the polymerization reaction prior to polymer processing to deactivate the polymerization catalyst and can increase the throughput of the polyester without adversely affecting the thermal stability of the polyethylene terephthalate polyester. Alternatively, the late addition of the stabilizer can increase the thermal stability of the polyester without adversely affecting the throughput of the polyethylene terephthalate polyester.

La tige comprend un évidement (9) présentant des parois opposées inclinées (15, 17) pour se mettre en prise avec une partie d'appui complémentaire pourvues de parois inclinées (25, 27) de la cartouche (3). L'évidement (9) et la partie d'appui complémentaire de la cartouche sont formés de telle sorte que la cartouche est calée dans l'évidement lorsque l'élément de fixation à vis (7) est serré. L'invention permet de réduire les coûts par un système de changement des cartouches et non plus de la totalité de l'outil de coupe. Le raccordement à cales de la cartouche et de la tige assure la rigidité de l'ensemble. Selon un mode de réalisation modifié, un évidement pour un élément à vis remplace un trou (23), ce qui permet de changer rapidement les cartouches.

Abstract: A channel estimating apparatus for performing channel estimation with high precision, and a CDMA receiver and a CDMA transceiver each having the apparatus. A channel estimation value of a data symbol is acquired from a series of pilot symbols which are in parallel with a series of data symbols.  First, a plurality of pilot blocks are generated from the pilot symbol series. By properly summing weighted average values of the pilot symbols included in the pilot blocks, the channel estimation value of the data symbol is determined. In such a manner, channel estimation can be performed with high precision. By performing the data symbol channel estimation by using not only the pilot symbols of a slot including the data symbol but also pilot symbols of other slots, the channel estimation can be carried out with higher precision.

Abstract: A downhole drilling tractor for moving within a borehole with predetermined speed, thrust and direction based on control signals from the surface and feedback signals from various sensors. The downhole drilling tractor of the invention comprises a tractor body, two packerfeet, two aft propulsion cylinders, and two forward propulsion cylinders. The body comprises aft and forward shafts and a central control assembly. The packerfeet and propulsion cylinders are slidably engaged with the tractor body. Drilling fluid can be delivered to the packerfeet to cause the packerfeet to grip onto the borehole wall. Drilling fluid can be delivered to the propulsion cylinders to selectively provide downhole or uphole hydraulic thrust to the tractor body. The tractor receives drilling fluid from a drill string extending to the surface. A system of spool valves in the control assembly controls the distribution of drilling fluid to the packerfeet and cylinders. The valve positions are controlled by motors. A programmable electronic logic component on the tractor receives the control signals from the surface and feedback signals from various sensors on the tool. The feedback signals may include pressure, position, and load signals. The logic component also generates and transmits command signals to the motors, to electronically sequence the valves. Advantageously, the logic component operates according to a control algorithm for intelligently sequencing the valves to control the speed, thrust, and direction of the tractor.
