Title: Sand exclusion liner for use in a wellbore
Inventor: BOHME CALVIN G
IPC: E21B43/10
Filed: 1997-08-13
Granted: 2002-03-26
Abstract: A conventional screened liner is modified to enable fluid circulation through its length when working it toward a landing position in a horizontal wellbore. At surface, a sleeve of heat-liquefiable sealant (such as wax or tar) is formed internally in each perforated liner joint to blind the liner openings. The sleeve may have a central longitudinal bore formed therethrough or alternatively the sleeve is bored out to fully re-open the joint bore. In either case, the bore through the blinded joints enable circulating the liner into the wellbore. Once the liner is in place, the sealant can be removed by circulating steam past it to liquefy it. By providing bore-forming blinded screen joints, it is now possible to circulate through the entire length of liner to remove sand blockages without reversing fluid flow through the liner openings.

Abstract: Plaque de scellement résistant à l'explosion conçue pour une cellule confinée et son procédé de fabrication consistant à couper le courant quand la pression intérieure de la cellule augmente et, également, à limiter la croissance de la résistance sous l'effet de la perméabilité d'un électrolyte. Il est possible, de ce fait, d'empêcher la cellule d'exploser dans le cas d'une génération anormale de gaz provoquée par des réactions chimiques dues à la surcharge ou à un fonctionnement erroné, et, par conséquent, de protéger le dispositif alimenté par la cellule.

Title: Pivotal latching mechanism with interengageable latch arm and catch in a sectionalizer assembly
Inventor: CLARK DAREN A
IPC: H01H31/28
Filed: 1998-08-25
Granted: 2008-04-08
Abstract: A sectionalizer assembly includes a mounting structure having upper and lower electrical contacts, a sectionalizer tube, an actuating member mounted to the tube and movable from a non-actuated to an actuated position, and a pivotal latching mechanism having a pivot member, latch arm and catch. The pivot member is mounted to the lower electrical contact and to a lower end of the tube for undergoing pivotal movement relative thereto between locking and releasing positions. The latch arm fixedly attached to the pivot member extends outwardly therefrom and undergoes pivotal movement therewith between the locking and releasing positions. The catch is carried on a lower end of the actuating member and undergoes movement therewith. The latch arm has an outer end fittable within a recess in the catch that is open at least at one side thereof. The latch arm outer end interengages the catch within the recess thereof when the actuating member is at the non-actuated position and the pivot member is at the locking position. Such interengagement tends to maintain the pivot member in the locking position. The latch arm outer end disengages the catch recess as the actuating member is moved from the non-actuated position to the actuated position and the pivot member is moved from the locking position to the releasing position. The movement of the catch with the actuating member from the non- actuated position to the actuated position causes the latch arm to pivotally move away from and disengage the catch, permitting an upper end of the tube to move from a closed to open position relative to the upper electrical contact.

Abstract: The present invention relates to an ultra wide band coherent radar system assessing the Doppler shift of the returned radar echoes, which radar system optimises the radio interference discrimination capability. The radar system comprises a control unit by which the transmit-receive process is partitioned into a number of consecutive sub-processes each of which consists of transmission followed by reception of a signal having a relative bandwidth of a fraction of an octave and where the received signals from the different narrow band transmissions are used to reconstruct broad band radar data by pulse compression techniques. Further, the control unit is arranged to determine the recurrence time, i.e. the time lapse between two consecutive transmissions, of a narrow band signal for a certain frequency step to be approximately inversely proportional to the frequency of this step and higher or equal to the Nyquist rate with respect to the Doppler bandwidth at this frequency.
