Abstract: An advanced overfire air system for NOx control designed for use in a firing system of the type that is particularly suited for use in fossil fuel-fired furnaces and a method of operating such a furnace which embodies an advanced overfire air sys-tem. The advanced overfire air system for NOx control includes multi-elevations of overfire air compartments consisting of a plurality of close coupled overfire air compartments (84, 86) and a plurality of separated overfire air compartments  (94, 96, 98). The close coupled overfire air (84, 86) compartments are supported at a first elevation in the furnace (10) and the sepa-rated overfire air compartments (94, 96, 98) are supported at a second elevation in the furnace (10) so as to be spaced from but aligned with the close coupled overfire air compartments (84, 86). Overfire air is supplied (106, 92) to both the close coupled overfire air compartments (84, 86) and the separated overfire air compartments (94, 96, 98) such that there is a predeter-mined most favorable distribution of overfire air therebetween, such that the overfire (106) air exiting from the separated over-fire air compartments (94, 96, 98) establishes a horizontal "spray" or "fan" distribution (124, 126, 128) of overfire air over the plan area of the furnace, and such that the overfire air (106) exits from the separated overfire air compartments (94, 96, 98) at velocities significantly higher than the velocities em-ployed heretofore.

Inventor: SCHULTZ ROGER L
IPC: E21B49/08
Filed: 1993-08-30
Abstract: Methods of draw-down and build-up testing on existing production  wells  are  disclosed.    The  testing  may  be accomplished without removing the production tubing string from the well.  The production of the well is shut down and then a  coiled tubing test  string  is run down  into the production tubing string.   The coiled tubing test string includes a coiled tubing string, a tester valve carried by the coiled tubing string, and a test packer carried by the coiled tubing string.   The test packer is set within one of the casing bore and the production tubing bore above perforations which communicate the casing bore with a subsurface formation.          Draw-down and build-up testing of the subsurface formation can then be accomplished by opening and closing the tester valve to selectively flow well fluid up through the coiled tubing string or shut in the coiled tubing string.  After the draw-down/build-up testing is completed, the coiled tubing test string is removed from the well and production of the well is resumed  up  through  the  production  tubing  bore  of  the production tubing string.  Optionally, the coiled tubing test string may carry a perforating gun to perforate a new zone of the well which may then be tested.

Title: Method for preparing tinted contact lens
Inventor: MOLOCK FRANK F
IPC: C08F20/20
Filed: 1993-10-22
Abstract: An improved method is disclosed for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization.        The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens.      Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens.
