Patent CA-2237321-C (CA)
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B10/64
Filed: 1996-10-25
Granted: 2004-10-05
Abstract: La présente invention concerne un manchon (10) constitué d'un élément cylindrique (12) pourvu en l'une de ses extrémités de deux dents de forme générale fuselée (16, 18) se faisant vis-à-vis. L'une de ces dents (16) est plus haute (longue) que l'autre (18). Le manchon (10), qui vient s'enclencher dans une réduction d'entraînement (26) d'un trépan, n'est capable que d'un déplacement linéaire le long de la réduction. Les dents (16, 18) coopèrent avec des cliquets de verrouillage (20, 22) disposés régulièrement autour de l'outil de pose (24) sur lequel ils se présentent radialement. Lorsque l'outil de pose (24) descend dans la réduction d'entraînement (26) et pénètre dans le manchon (10), l'un des cliquets de verrouillage (20, 22) vient au contact de l'une des dents (16, 18), faisant ainsi tourner l'outil (24) qui vient prendre une position angulaire préétablie. Etant donné que les dents (16, 18) n'ont pas la même hauteur, les cliquets de verrouillage (20, 22) ne peuvent pas toucher en même temps le sommet proprement dit de chacune des dents (16, 18). Lorsque le premier cliquet de verrouillage (20) vient percuter le sommet de la dent la plus haute (16), il est obligé de descendre au contact du bord de cette dent, ce qui force l'outil (24) à tourner. L'autre cliquet de verrouillage (22) est alors amené à toucher un bord opposé ou plus éloigné de la dent (18). De ce fait, les cliquets de verrouillage (20, 22) ne peuvent pas descendre au contact de bords adjacents des dents, ce qui risquerait de coincer l'outil (24).

Abstract: Ce corps de collecteur à soupapes, en une seule pièce, (120) pour un transmetteur de pression, comprend quatre trous (160, 161, 162, 163) destinés au montages d'instruments, dont les centres définissent les angles d'un prisme imaginaire. Les chambres de soupapes, qui définissent des sièges de soupape respectifs (148, 152 etc.), sont disposées de telle sorte que les sièges de soupape, et au moins une partie de chacune des chambres, soient tous contenus dans le prisme imaginaire. Deux alésages de soupapes, de préférence des alésages de soupapes de mise à l'air libre (148, 152), sont usinés dans l'une (125) des parois périphériques du corps du collecteur. Ces alésages sont pourvus de soupapes du type comportant une tige de soupape venant en contact étanche contre la chambre de soupape (14, 152) plutôt que contre le chapeau. Tous les passages (142, 145 etc.) du système de voies du collecteur sont rectilignes, se trouvent dans ledit prisme et sont parallèles au moins à l'une des parois externes planes (123, 124, 125 etc.) du bloc collecteur, ce qui simplifie la fabrication de ce dernier.

Abstract: The present invention relates to an apparatus for protecting and insulating an electrical connection in a hazardous area adjacent a wellhead barrier of a well enclosing fluids.  The electrical connection is between a first electrical conductor extending from a non-hazardous area and a second electrical conductor extending through the wellhead barrier.  The second electrical conductor includes a conductive portion circumscribed by insulation.  The apparatus is comprised of a unit for electrically and mechanically coupling the first and second electrical conductors together forming the electrical connection.  A breather boot is provided for protecting and insulating the electrical connection.  The breather boot includes an inner cavity for containing the electrical coupling unit, a first opening for receiving the first electrical conductor and a second opening for receiving the second electrical conductor. The insulation is terminated  within the breather boot.  A header space is located where the insulation is terminated within the second opening.  A gas block seal passage is provided adjacent the header space allowing passage of the conductive portion of the second electrical conductor from the second opening to the electrical coupling unit.  A breather passage is provided which allows fluid communication between the header space and the area surrounding the breather boot.  The breather passage and the header space are filled with a dielectric compound so that in the event well fluids escape between the insulation and conductive portion of the second electrical conductor the well fluids will escape without migrating through the gas block seal passage.

Title: Rate control for mpeg transcoder without a priori knowledge of picture type
Inventor: EIFRIG ROBERT O
IPC: H04N21/434
Filed: 1999-10-18
Granted: 2009-07-14
Abstract: A rate control system suitable for use with a digital video transcoder, such as one conforming to the MPEG standard. The proposed rate control system starts coding with any reasonable set of assumed Group of Pictures (GOP) parameters, thereby avoiding a processing delay of about one GOP which would otherwise be incurred to extract the complete GOP structure information from a pre-compressed bit stream. In addition, the system avoids the need to store the data corresponding to the GOP, thereby reducing the memory required for transcoding. Encoding of a first picture in a sequence or GOP begins without a priori knowledge of the picture type of subsequent pictures. A reasonable set of GOP parameters is assumed to determine an encoding bit budget. The bit budget is gradually corrected as successive pictures are coded according to their picture types. Changes in the GOP structure of pre-compressed bitstreams can be addressed, for example, when switching channels, inserting commercials, and the like. Target rates with incorrect starting GOP parameters will converge within a few GOPs.

Abstract: A satellite receiving an-tenna (16) at a user location (14) receives satellite signals at a first frequency from a satel-lite (12). The satellite signals travel along a satellite signal route (42) within a look an-gle about the centerline (28) of the antenna (16). A  ter-restrial transmitter (20) trans-mits signals at the first fre-quency along a wireless trans-mission route (40) from the transmitter to the user location (14). The terrestrial transmit-ter (20) is located with respect to the user location (14) so that the wireless transmission route (40) is at a relatively large an-gle to the centerline (28) of the first antenna (16). The an-gle of the wireless transmission route (40) to the satellite an-tenna centerline (28) is large enough so that the terrestrial signals present at the location (14) result in terrestrial input signals from the antenna (16) which are less than an interfer-ence level with respect to satellite input signals produced by the antenna. Thus, the terrestrial signals do not interfere with the satellite signals even though they are transmitted at a common frequency.
