Title: Aluminum charge air cooler and method of making the same
Inventor: BRETL RICHARD A
IPC: F28D1/06
Filed: 1992-06-03
Granted: 2004-01-06

Title: Method and apparatus for combined cylindrical and spherical eye corrections
Inventor: SHIMMICK JOHN
IPC: A61F9/00
Filed: 1992-07-14
Granted: 2003-04-01
Abstract: A method for performing concurrent spherical and cylindrical corrections to the corneal surface of the eye to reduce myopia and astigmatism. A laser beam irradiates the corneal surface via a variable diameter iris and a slot produced by a pair of translatable blades. The width of the slot and the diameter of the iris are varied as the laser is pulsed to produce a toric ablation of the corneal surface. Alternatively, the laser beam is passed through a succession of apertures in a tilted variable aperture element to produce toric ablation. The total number of laser pulses required to effect both types of correction is equal to the number required for the spherical correction alone, reducing the laser power and the procedure time. The toric ablation produces no steep end walls as with standard cylindrical ablation procedures, thereby eliminating hyperopic shift and minimizing flattening along the ablated cylinder axis.

Title: Apparatus and method for completing and recompleting wells for production
Inventor: DALLAS L MURRAY
IPC: E21B33/00
Filed: 1994-10-18
Granted: 2000-07-25
Abstract: An apparatus and method for completing or recompleting wells for production is disclosed. The apparatus and method are particularly adapted to the completion of oil or gas wells having a plurality of production zones. In particular, the apparatus is useful for oil or gas wells having production zones which require stimulation prior to initial production of the well, or producing wells which require recompletion in order to open new zones or to reperforate and stimulate existingzones from which production has slowed down or ceased. The apparatus comprises aheader spool having a pressure rating that is about as high as the burst pressure rating of the surface casing of the well. The header spool is mounted to a casing spoolbefore a 1 is placed on the well. The header spool has an internal passage which is at least as large as the diameter of the casing in the well. This permits an efficient completion of the well after the casing is cemented in. The apparatus in accordance with the invention permits the unobstructed use of a full range of tools including casing perforation tools, blowout preventers, casing plugs, logging tools, fishing tools, and other apparatus required in the completion of a well for production. The method for completing wells involves installing a header spool in accordancewith the invention on the well before a wellhead is installed and performing the steps required to perforate the casing and stimulate or fracture the zones requiring treatment in order to prepare the well for production before wellhead equipment is installed. This method and apparatus permits a well to be completed at a significantly less cost than for completing a multi-zone well in the traditional manner of completing after the wellhead equipment is installed.

Abstract: A circumferential flow path (86) is established about an axis of rotation, while the circumferential flow path (86) is rotated about the axis. Blood is introduced into the rotating circumferential flow path (86) through an inlet port (122) having an axis that is parallel to the axis of rotation. The axial inlet flow together with the circumferential separation flow creates a vortex region (148) that circulates about the port axis and stretches across the circumferential flow path (86). The vortex region (148) perfuses the blood uniformly into the circumferential flow path (86) for separation into constituent parts.

The resulting inner codes are preferably diagonal-scan interleaved before recording, at least for the normal-play data. During reproduction, after de-interleaving when interleaving was performed during recording, the inner error-correction coded data are decoded and separated into trick-play data and outer error-correction coded normal-play data.      Outer error-correction coded normal-play data are decoded during normal play.
