Patent MX-2007000641-A (MX)
Title: Bonded fiber structures for use in controlling fluid flow.
Inventor: XIANG JIAN
IPC: D04H3/16
Filed: 2005-07-21
Abstract: A flow control element is provided for use in selectively controlling the flow of a liquid through an annular conduit. The flow control element comprises a self-sustaining, three dimensional fibrous element comprising a network of polymeric fibers. These fibers are disposed in a highly dispersed and randomly spaced orientation and are bonded to each other at spaced apart points of contact to form a tortuous interstitial passage through the fiber element. The fibrous element has a substantially uniform density and is sized for disposition in the lumen with an interference fit relative to the inner conduit surface. The fibrous element divides the lumen into a proximal lumen portion and a distal lumen portion when so disposed. The fibrous element is adapted to prevent passage of the liquid through the conduit when disposed therein absent a differential pressure between the distal conduit portion and the proximal conduit portion of at least a first predetermined critical differential pres sure. The fibrous element allows passage of the liquid through the conduit when the differential pressure between the distal conduit portion and the proximal conduit portion equals or exceeds the first predetermined critical differential pressure. In some embodiments, the fibrous element may also be adapted so that it will move from its first position in the lumen to a second position when the differential pressure between the distal conduit portion and the proximal conduit portion equals or exceeds a second predetermined critical differential pressure.

Patent MX-2007005363-A (MX)
Title: Method and apparatus for laminating glass sheets.
Inventor: ALA-SAVIKOTA JARI
IPC: C03C27/00
Filed: 2005-11-04
Abstract: The invention relates to a method and apparatus for laminating glass sheets. A first glass sheet is passed onto a laminating conveyor (1) and raised by a lift mechanism (3) to a distance off the conveyor (1). The lift mechanism (3) is held stationary and a second glass sheet is placed under the first one. A plastic film is drawn to cover the second glass sheet and the first glass sheet is lowered by the lift mechanism (3) on top of the second glass sheet and the plastic film. This lowering process involves performing an alignment of the glass sheets by manipulating a carrier rack (8) at a distal end of the lift mechanism's pickup arm (7) relative to the pickup arm (7). Three-sheet lamination can be performed by displacing two superimposed glass sheets, with a plastic film therebetween, by the laminating conveyor (1) from below the lift mechanism. A third glass sheet is passed onto the laminating conveyor to below the lift mechanism (3) and raised by the lift mechanism to a distance of f the conveyor (1). A plastic film is drawn to cover the top surface of said two superimposed glass sheets and this bundle is returned to below the third glass sheet. Finally, the third glass sheet is lowered by the lift mechanism (3). This arrangement is capable of providing a shorter-than-conventional laminating room, which is beneficial for the reason that the laminating room must be an air-conditioned clean space.

Title: Methods and compositions for diverting acid fluids in wellbores.
Inventor: CREWS JAMES B
IPC: C09K8/72
Filed: 2008-03-19
Abstract: Viscoelastic surfactant (VES) gelled aqueous fluids containing a VES, an internal breaker, and optionally a viscosity enhancer are useful as diverting fluid for directing placement of an acid into a subterranean formation, where the acid is injected subsequent to introducing the VES gelled fluid.

The VES gelled fluid may optionally contain a fluid loss agent which increases the viscosity of the fluid and/or facilitates development of an external viscous VES fluid layer (e.g. a pseudo-filter cake) on the formation face. The VES gelled fluid may also optionally contain an agent that stabilizes the viscosity of the fluid, for instance at high temperatures, such as MgO, Mg(OH)2, CaO, Ca(OH)2, NaOH, and the like.
