Title: Appareil et procede pour puits de production
Inventor: THOMAS WAYNE
IPC: E21B43/12
Filed: 2001-05-29
Abstract: Un appareil pour puits de production comprend une pompe à engrenages et un ensemble de transport auquel est attachée la pompe à engrenages. L'ensemble de transport est formé d'un train d'assemblages de tuyaux modulaires possédant un ou plusieurs passages destinés au transport du fluide de production depuis le fond du puits jusqu'à la surface. Les passages peuvent être aménagés côte à côte et comprennent des conduites de pression et de retour destinées à l'entraînement de la pompe à engrenages. La pompe à engrenages comprend un moteur à entraînement hydraulique qui est équipé d'un ensemble d'engrenages à déplacement positif. Le moteur et la partie de pompage ont des surfaces d'usure céramiques, la céramique étant sélectionnée pour avoir des coefficients de dilatation thermique correspondant aux coefficients de dilatation thermique des ensembles d'engrenages. Les pompes et rotors ont des garnitures d'étanchéité céramiques plutôt que des roulements à billes ou des coussinets et peuvent fonctionnent dans des conditions d'abrasivité.

Title: Method and apparatus for limiting the utilization of a system bus with distributed controlled access for alleviating saturation
Inventor: BARLOW GEORGE J
IPC: G06F13/368
Filed: 1990-01-09
Abstract: A plurality of units which are coupled to transfer requests,  transfer  data  over  an  asynchronous  bus network during allocated bus transfer cycles.   The network has a tie-breaking bus priority network which is distributed to a common interface portion of each of the plurality of units and grants bus cycles and resolves simultaneous requests on a priority basis.  At least  one  unit  includes  bus  saturation  detection apparatus included within its common interface portion for monitoring bus activity over established intervals of time. The detection of the occurrence of at least one available cycle over the given interval of time signals that the bus network is not in a saturated state.   When the indicator specifies that the bus network is saturated,  the unit throttles down  its operation by increasing the amount of time between issuing data requests.  Throttling continues until the bus is no longer being saturated.

Inventor: MCNEILL ANDREW B
IPC: H01R9/00
Filed: 1990-06-01
Abstract: ABSTRACT      A plug-in feature board for  a  computer  system has special circuitry to permit the board to customize itself to the particular slot into which it is inserted.  Computers of the  type  intended  for  individual  use  or use  in  small networks  typically  provide  insertion  slots  including connectors  to  permit  feature  boards  to  be  added and connected to a bus of the computer for adding new function or capacity.  As the computing power of such systems has increased there have been increases in the size of portions of  the  connecting  bus  to  permit  improvements  in  data transfer performance.  In a given computer system there are often two or more bus connector configurations presented in respective slots.   By so converting electrical states at selected   connector   positions   as   to   provide   signal information for determining bus configuration for the slot, special logic provided on the board is enabled to determine the characteristics of the slot in which the board is placed and customizes the board to respond or limit response in accordance with the requirements for that configuration.  By so  adapting  to  the  slot  the  board  achieves  enhanced applicability   and   avoids   certain  system   disabling malfunctions which can occur when a board is plugged into a slot for which it is not configured.

Title: Active polarization control servo and method
Inventor: DANKOWYCH JOHN A
IPC: H04B10/00
Filed: 1990-07-12
Abstract: ACTIVE POLARIZATION CONTROL SERVO AND METHOD               Abstract of the Disclosure An active polarization control system, which provides two dimensional optical waveguide birefringence modulation, provides polarization control in systems such as fiber optic rotation sensors and coherent fiber optic communications systems without the necessity of using costly polarization preserving fiber. In a rotation sensor, the signal output from the sensing loop is used to form feedback signals for correcting polarization state errors. The feedback signals are used to provide the corrective voltage applied to two banks of orthogonally modulated birefringence transducers situated inside the rotation sensing loop. In a coherent fiber optic communications system orthogonal modulation of two banks of birefringence transducers situated in either the communications or local oscillator signal arms at the receiver provides the required feedback signals for polarization control. The polarization of light guided by an optical waveguide is controlled by adjusting the birefringence of the optical waveguide with a first transducer and a second transducer arranged to act on the optical waveguide along parallel axes and a third transducer being on an axis that is placed between the parallel axes and angularly displaced by 45° therefrom. A first control signal is applied to each of the first and second transducers, and a second control signal in time quadrature with the first control signal is applied to the third transducer.
