Title: Compact press section with closed draw of the web in a paper machine
Inventor: KARVINEN MIKKO
IPC: D21F7/00
Filed: 1992-12-18
Granted: 1996-06-04
Abstract: Closed press section in a paper machine, comprising a compact combination of press rolls.  Certain of rolls define press nips with each other, between which nips the web has a closed draw supported by the face of a fabric.  The press section has a center roll in connection with which a press nip or press nips are provided.  A closed loop of a transfer band is passed around the center roll.  The web is transferred on an outer face of the transfer band after the last press nip in the compact combination of rolls as a closed and constantly supported draw onto a drying wire in a drying section following after the press section.  The transfer band loop is made of a transfer band fabric that substantially does not receive water and does not rewet the web.  The web-adhesion properties of the outer face of the transfer band fabric are chosen so that, after the last nip, the web follows the transfer band fabric, and so that the web can be transferred as a fully closed draw onto the drying wire.  In connection with the loop of the transfer band fabric, means for conditioning of the band and/or safety devlces are provided, by whose means an adequate operation of the transfer band fabric is maintained.

Granted: 1995-07-18
Abstract: Method and apparatus for supplying from a vessel to a pump liquified gas with subcooling so as to avoid cavitation during pumping.  A supply conduit supplies liquified gas from the vessel bottom to a pump sump which envelops the flowpath elements of a pump and the pump suction.  A return conduit returns vapor and excess liquified gas from the sump to the bottom of the vessel.  Heating means, preferably heat leak into the return conduit, reduces the density of the fluid in the return conduit thereby increasing the rate of liquified gas flow in the supply conduit and reducing its temperature rise enroute to the pump.  Further subcooling is secured by locating the intake to the supply conduit remote from a wall of the vessel in a cooler strata of liquid, and the discharge of the return conduit proximate to a wall of the vessel in a warmer strata in the vessel. The low flow friction losses in the supply and return conduits enhance the circulation rate of liquified gas in the conduits, and the short supply conduit reduces the heat leak into the liquified gas flow in the supply conduit, so that sufficient subcooling is achieved with reduced elevation of the vessel above the pump sump and reduced pressurization of the vessel compared to prior art.

A cationic nitrogenous softener/debonder is preferably added to the furnish, in an amount of from about 1 pound per ton to about 6 pounds per ton. The CD dry tensile strength of the paper product is from at least about 133 g/1" up to about 267 g/1", and the tensile modulus is from about 10 to about 32 g/% strain while the GM MMD friction is from about 0.26 to about 0.10. Preferably, the wet strength of the product decays with sufficient speed that the CD wet tensile strength drops to about 15 g/1" strip within 10 hours after immersion. When rubbed against a skin-like surface in a moistened condition, the paper product remains substantially free of pilling.

Title: Ligase chain reaction with endonuclease iv correction and contamination control
Inventor: BACKMAN KEITH C
IPC: C12Q1/6862
Filed: 1994-04-13
Granted: 2000-08-22
Abstract: The present invention involves methods of improving the Ligase Chain Reaction (LCRTM) amplification schemes by modifying at least one probe end so that the probability of the probe contributed to spurious ligation and signal development is greatly reduced. Only after specific hybridization of the modified probe with true target are the modified ends "corrected" by endonuclease IV in a target dependent fashion to allow participation of the probe in the enzymatic ligation reaction. Specific modifications include 3' phosphate blocking groups and nucleic acid overhangs containing an abasic site at the point of ligation. Further embodiments include probes modified to contain ribonucleotide moieties which, after amplification, can be cleaved by RNase to destroy the amplification products and reduce the risk of contamination.
