Abstract: : Dans une zone pétrolifère, surmontant une zone aquiière, on réalise une stimulation par balayage latéral au moyen d'un fluide capable de déplace les effluents pétroliers (un fluide chaud tel que de la vapeur, un solvant etc), que l'on injecte dans (a formation par un drain d'injection dévié (horizontal par exemple) et on souti?e l'huile déplacée par le fluide de déplacement, au moyen d'un drain de soutirage décalé latéralement par rapport au premier et sensiblement parallèle à lui. Pour éviter que l'huile ne soit déplacée jusqu'à l'aquifère et ne reste piégée dans celui-ci, on fore dans la zone pétrolifère un troisième drain et éventuellement un quatrième drain plus proches de l'interface avec l'aquifère que le premier et le deuxième drain. Par une circulation d'eau (injection et/ou soutirage) établie au moyen de ce troisième drain et/ou de ce quatrième drain, on limite considérablement le piégeage les lignes de déplacement des effluents fluidifiés vers le deuxième drain. Application à la stimulation de formations pétrolifères.

Title: Apparatus and method for the delamination of a laminate
Inventor: SCHUH DANA F
IPC: B41M5/382
Filed: 1992-10-22
Abstract: Abstract of the Disclosure Apparatus and method for delaminating a composite sheet structure of the kind comprising a vertically frangible layer having a first surface adhesively bonded to a first sheet at a substantially uniform strength and an opposite surface abutting areas which are, respectively, adhesively bonded to a second sheet at strengths less or greater than the uniform strength and having a marginal portion or tab extending beyond the first sheet.  The composite sheet structure is fed into the nip of upper and lower peel rollers and upon passage therethrough a strip sheet roller is rotated into position to bend and hold the laminate against the upper peel roller in a position to fracture the tab from the first sheet.  On reversal of the feed direction and passage of the laminate back through the nip of the strip sheet and upper peel rollers, the thicker "keeper sheet" of the flexed laminate breaks from the "throw-away" sheet containing the tab, at the preformed tab.  A roller configuration and drive train structure are provided, for a more predictable and repeatable steady state condition and allows for control of the location of the peel point.

Title: Filter for a rockdrill
Inventor: LYON LELAND H
IPC: B01D29/17
Filed: 1993-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      A filter having a filter element is provided for a rockdrill.  The filter can be operated in three modes, namely, filtering or drilling, rinsing and back-flushing.   As the filter element becomes clogged a handle on the filter can be turned to a back-flushing mode position whereby the flow of fluid through the filter element is reversed and the flow of fluid thereby expels dirt and debris accumulated in and on the filter element to the atmosphere through the a outlet port.          When the handle is turned back to a filtering mode position ports in a support shaft in the filter pass through the rinsing mode which washes dirt that may have accumulated on the filter element during the back-flushing mode and expels it to the atmosphere through the vent outlet port.  When the handle is positioned in the filtering mode position the filter element is clean.

Abstract: A session-oriented local area network (LAN) application and an ISO 8802-2 protocol driver code will cooperate in a new form  of  connectionless,   session-oriented  communication called Sideband.  At each  session start-up time,  the LAN Application will communicate with the enhanced ISO 8802-2 based protocol  driver  on  the  local  system  and  the  LAN Application and the 8802-2 based protocol driver on the remote system to determine if they all support the Sideband. If Sideband is fully supported by both systems,  Sideband will be  activated for the  session.  To  communicate  on a session  which  has  Sideband  active,  the  LAN  Application requests that data is to be sent using the Sideband.   A check  is  performed  to  see  if  the  data  meets  Sideband criteria.  As  Sideband  is  a  connectionless  medium,  the additional code path needed to set Up and track timers and to handle the resend attempts are saved in the protocol. If the LAN Application code is session-oriented, it will keep track of a timer which will cause the data to be resent along a non-Sideband path if a  response is not received within a designated amount of time. Header information is stored and reused to increase the throughput and decrease the  response  time  for the  transmission of  small network packets.  In  case  the  network  at  some  points  becomes unreliable, procedures are used to track the reliability of the network and to enable and disable Sideband in accordance with the reliability of the network.
