Title: Improved dewatering of a paper web in a press section of a papermaking machine and press felt therefor
Inventor: JACKSON GRAHAM
IPC: D04H5/00
Filed: 2004-12-21
Granted: 2009-07-21
Abstract: A press felt for a papermaking machine comprises at least one base fabric layer to which at least one batt layer is attached, preferably by needling. A woven or nonwoven fibrous scrim may be included between any two layers in the felt. At least one of the base fabric, the batt layer or layers, or the scrim comprises regenerated cellulosic staple fibers, together with polymeric fibers.  Additionally, regenerated cellulosic material can be provided in the scrim, or in yarns in a woven base fabric.  The regenerated cellulosic fibers can have a modulus of elasticity substantially less than that of the polymeric fibers. The press felt provides a retarded elastic spring-back in the vertical direction of the felt following the mid-nip point in the press section, advancing the post nip separation position of the felt and the paper web towards the mid-nip point, thus reducing rewetting of the paper sheet.

Abstract: The disclosure relates to an apparatus for insertion of a conduit into a well system bore to introduce a reactant fluid over a subterranean catalyst to initiate decomposition of the reactant fluid which resultant energy release may be utilized to perform work or perform heating of the subterranean environment. The reaction may be further accelerated by the addition of a fuel down into the reaction chamber or blended with the reactant fluid at a surface location. Reaction products can be jetted from a reaction chamber orifice against the proximal surface of the well system bore which may be either a production zone for the purpose of stimulating production or against a casing to perforate the casing and expose the production zone adjacent such perforation. The energy released from said catalytic reaction and subsequent combustion of fuels may also be used for cutting, welding, powering pumps, compressors, turbines, generators, or to heat well system fluids, pipes, subterranean reservoir fluids, subterranean solids, and completion devices in the well system.

Inventor: RAKUS PAUL R
IPC: H01H77/10
Filed: 2006-01-12
Granted: 2014-09-09
Abstract: A moving contact assembly for high-current interruption electric power switching apparatus has an inner carrier for the contact fingers that is rigidly held in a withstand position in an outer carrier by a spring biased cam follower pin engaging a cam profile on the inner carrier and configured to positively seat an inner carrier stop against an outer carrier stop on the outer carrier and to rapidly drive the inner carrier to a blow open position in response to a fault. The cam profile has an extended width divided between spaced apart cam profile sections to absorb the high closing and withstand forces. An abutment on the outer carrier resists bowing of the cam follower pin between the cam profile sections. Complementary convex and concave partial cylindrical surfaces on the inner carrier and a gas shield on the moving assembly carrier body maintain an arc gas seal during blow open.

Abstract: Electrospray ionization sources interfaced to mass spectrometers have become widely used tools in analytical applications, Processes occurring in Electrospray (ES) ionization generally include the addition or removal of a charged species such as H+ or other cation to effect ionization of a sample species. Electrospray includes ionization processes that occur in the liquid and gas phase and in both phases ionization processes require a source or sink for such charged species Electrolyte species, that aid in oxidation or reduction reactions occurring in Electrospray ionization, are added to sample solutions in many analytical applications to increase the ion signal amplitude generated in Electrospray and detected by a mass spectrometer (MS). Electrolyte species that may be required to enhance an upstream sample preparation or separation process may be less compatible with the downstream ES processes and cause reduction in MS signal New Electrolytes have been found that increase positive and negative polarity analyte ion signal measured in ESMS analysis when compared with analyte ESMS signal achieved using more conventional electrolytes. The new electrolyte species increase ES MS signal when added directly to a sample solution or when added to a second solution flow in an Electrospray membrane probe, It has also been found that running the ES membrane probe with specific Electrolytes in the second solution of the ES membrane probe have been found to enhance ESMS signal compared to using the same electrolytes directly in the sample solution being Electrosprayed The new electrolytes can be added to a reagent ion source configured in a combination Atmospheric pressure ion source to improve ionization efficiency,
