Title: Liquid removal method, system and apparatus for hydrocarbon producing wells
Inventor: AMANI MAHMOOD
IPC: E21B34/00
Filed: 1988-11-03
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus are disclosed to detect periodic well loading by produced accumulated secondary fluids, and accordingly to remove the undesired secondary fluid from the tubing of a hydrocarbon producing well.  The method according to the present invention employs a surface control  system that controls  the operation of the fluid removal cycle, and the production cycle of the  hydrocarbon  producing  well.   Periodically,  the  well  is "shut-in" and upper and lower flow control valves, connected at a predetermined depth to the well tubing, are actuated to a closed position to form an accumulation chamber within the tubing.  The closed  flow  control  valves  block  off  the  fluid  in  the accumulation chamber formed in the lower portion of the tubing string,  which  contains  the  undesired  accumulated  secondary fluids.  A supply line is used to inject pressurized gas from the surface of the well into the accumulation chamber to provide the necessary pressure to force the accumulated secondary fluids, trapped in the accumulation chamber, through a relief valve and into  the  annulus  of  the  well  casing  thereby  removing  the undesired secondary fluids from the well tubing.  The controller then stops the flow of the injected gas to the supply line to stop the removal cycle.  The supply line pressure is relieved, and the pressure across the flow control valves are equalized.          The flow control valves are then opened and the producing well is returned to production with reduced back pressure due to the removal of the undesired, accumulated secondary fluids from the tubing.

Abstract: EMBOSSING MACHINE FOR TEXTILE MATERIALS                   ABSTRACT An embossing machine wherein two driven embossing rolls are provided with peripheral knobs and depressions.  The knobs of one roll extend with clearance into the depressions of the other roll and vice versa during travel of the knobs and depressions through the nip of the rolls.  The clearances between the top lands of knobs and adjacent portions of internal surfaces bounding the respective depressions are smaller than the clearances between the flanks of the knobs and the adjacent portions of the respective internal surfaces.  This ensures that a carpet of loose fibrous material which is fed into the nip is converted into embossed textile material having a first layer of compacted portions which are formed adjacent the top lands of knobs on one of the rolls, a second layer of compacted portions which are formed adjacent the top lands of knobs on the other roll, and fluffy intermediate portions which connect the compacted portions forming one of the layers with compacted portions of the other layer. The knobs of one or both rolls can be heated to weld the filaments of the compacted portions to each other. Alternatively, or in addition to heating, those parts of the carpet which are to be converted into compacted portions can be impregnated or sprayed with a suitable solvent.  The height of the knobs determines the thickness of the embossed textile material.

Title: More efficient call handling for operator assistance calls
Inventor: BAUER THOMAS M
IPC: H04M3/42
Filed: 1989-08-04
Granted: 1992-08-25
Abstract: MORE EFFICIENT CALL HANDLING FOR OPERATOR ASSISTANCE CALLS Abstract A method and apparatus for processing operator assistance calls with minimum expenditure of operator work time. For collect and person-to-person calls, a first operator at a first operator position determines the type of call and, optionally, the name(s) of the calling and called parties. These are recorded in the memory of a program controlled processor system for controlling an operator assistance switching system. The first operator then disconnects from the call while the call is being set up and the called party being alerted. When the called party answers, a second operator position and second operator, having a display of the call information previously recorded, are attached to the call to determine whether a connection between the calling and called parties should be established and, if so, to cause that connection to be so established. Advantageously, no operator position and operator need be attached to the call while the called party is being alerted; even more operator work time is saved if the called party never answers.

Filed: 1989-09-29
Granted: 1995-07-04
Abstract: The method for the enhanced recovery of hydrocarbons from a hydrocarbon bearing reservoir during gas injunction into the reservoir comprises the at least periodic injection of steam and a foam-forming mixture into the reservoir from a known depth interval in a well source to provide a foam in the presence of residual oil and high gas permeable channels of the reservoir.          The mixture comprises water, an effective foam forming amount of an alkyl aromatic sulfate component having an average molecular weight from about 400 to about 600 and at least one alkyl group comprising 18 to 24 carbon atoms and a viscosity control agent.          The viscosity control agent comprises a surfactant which is present in an amount effective to prevent gelling of the mixture during storage.  The reservoir fluids are contacted with the resulting foam so as to assist movement of the hydrocarbons toward a producing interval and the hydrocarbons are recovered from the producing interval.

Abstract: A main valve (1) is connected into a pressurized water pipe for an irrigation installation and has a valve body (4) formed as a differential piston and with a through bore (5), said body being operated in both directions by means of the water pressure, the piston (4) in one end position closing the water pipe and in its other end position keeping it open. The piston (4) is guided to said end positions by means of a control valve (7) arranged to open or close a duct (6) starting from the major cylinder bore, thereby to cause the water present to actuate the piston (4). The control valve (7) is in turn controlled by rainfall onto, and evaporation from an upwardly open bowl (8), and a drop means (9) active during irrigation. The bowl (8) is part of a tipping means with two tipped end positions, controlled by the quantity of water in the bowl (8). To achieve operation of the main valve (1) such that irrigation substantially takes place at night, and that the length of time between irrigation can be varied, the tipping means is supplemented by a closed air chamber (15) on the other side of the pivoting shaft (35), said chamber and bowl (8) having a common flat bottom (16) and mutual communication via a slit (17) at the bottom. By the volume change in the air enclosed in the air chamber (15), caused by the temperature difference between night and day, the quantity of water contained in the open bowl (8) and in the chamber (15) is displaced at night such that the tipping means tips over into a position opening the main valve (1).

Abstract: New macroporous alkylaminophosphonic chelating resins wnich exhibit excellent mechanical stability and strength and good chemical stability are characterized by having an apparent density of 0.35 to 0.425 g/ml, a granulometry smaller than 0.8 mm, a water retention of 50 to 60 percent in the acid form, a porosity of 800 to 1100 mm<3>/g, a total theoretical capacity for the fixation of calcium ions of not greater than 31 g/l of resin in the sodium form and an osmotic resistance such that more than 90 percent of the beads are intact after 30 shocks. The high resistance to osmotic shock combined with an adequate exchange capacity exhibited by the new resins makes them particularly suitable for use in highly concentrated solutions, such as concentrated electrolytic brines. A simple, effective, and economical procedure is described which makes it possible to eliminate, in the form of complexed cations, the impurities contained in the brines used for the electrolytic production of chlorine or alkali metals in membrane cells or diaphragm cells and for the electrolytic production of chlorates.
