Filed: 1998-04-21
Abstract: A method and an equipment for evaporation drying of a paper web that comes from the press section of a paper machine in three successive stages I, II and III carried out in the direction of progress of the web. (I) in the first stage, the paper web coming from the press section of the paper machine is heated in a short section of the paper machine in the machine direction quickly to a temperature of 55°C to 85°C, and web breaks of the relatively moist and, thus, weak web are minimized; (II) the main evaporation drying of the web is carried out so that the evaporation efficiency and the rate of increase in the dry solids content of the web are substantially higher than in the first stage or in the final stage (III), and the web temperature does substantially not rise while the drying proceeds; (III) in the final stage, the drying is continued with a decreasing evaporation efficiency and with such an average rate of increase in the dry solids content of the web in the machine direction as is lower than in the preceding state (II) but higher than in a conventional cylinder drying with single-wire draw so that the paper quality can be controlled at the same time.

Title: System for drilling and completing multilateral wells
Inventor: ALLEN DAVID WAYNE
IPC: E21B/
Filed: 1997-06-09
Abstract: The time required for establishing a multilateral well is reduced by enlarging a section of a wellbore and running a multilateral tool (7) which includes a preassembled combination of casing sections that form dual casing strings extending from the primary casing. The multilateral tool (7) incorporates a carrier section (2), a lateral section (8), and a main section (5). The tool is run with the lateral section (8) releasably held in coaxial alignment within the carrier section (2), and with the main section (5) fixed to the lower end of the carrier section (2). Once in place, the lateral section (8) is released and diverted out of a preformed window (4) in the lower end of the carrier section (2) and runs generally parallel to the main casing section (5). A lateral junction is thus formed at the carrier section window (4) in which dual casing strings are connected to the primary casing. A second window, preformed in the upper end of lateral section (8) is aligned with the bore of the primary casing when the lateral casing section is fully extended out of the carrier section window (4), thus permitting recovery of a diverting device incorporated in the carrier casing section (2) through the second window. The dual strings are then individually drilled and completed with pressure integrity between the dual strings maintained by using straddle equipment across the lateral junction.

Title: Chevron error correction and autofocus optics for laser scanner
Inventor: YAO SHI-KAY
IPC: G02B26/08
Filed: 1998-06-19
Abstract: In a light raster scanning system imaging a medium (40) located on a movable stage and using bidirectional scanning, i.e. scanning during stage movement in two opposing directions, the problem of chevron artifacts (angle errors), due to the different stage movement directions, is overcome by a system of reflective optics including two optical elements (14, 16) dynamically movable relative to one another. One (14) of the optical reflective elements (14, 16) is tilted or rotated relative to the other to compensate for the angle error causing the chevron artifacts. The amount of this tilt is dynamically altered depending on the direction of stage travel and also may be dynamically adjusted to maintain linearity of the scan pattern in spite of any other irregularities in stage velocity. Also an autofocus feature is provided, whereby the two reflective elements (14, 16) are moved relative to one another to dynamically alter the focus of the light beam (12) onto the medium (40) and hence overcome any defocus problems due to irregularities in the medium surface.
