Abstract: A method for producing surface-treated paper, in particular of fine paper, and a dry end of a paper machine that makes use of the method. A paper web that has been dewatered by pressing is dried in the forward dryer section (D1), in which drying energy is applied to the paper web over the entire length of the forward dryer section asymmetrically in the z-direction from the side of the bottom face of the web. This step is carried out by a number of successive groups (R1-R8) with single-wire draw that are open downward. In this manner, shrinkage of the web both in the machine direction and in the cross direction is reduced or at least partially prevented, which shrinkage tends to take place when the dry solids content becomes higher. Paper broke is removed from underneath the drying groups that are open downward substantially by the force of gravity onto the broke conveyor (19) placed underneath. The paper web which has a tendency of curling because of the asymmetric forward-drying is passed to the finishing section (D2) where it is finished while it is moistened and worked plastically by passing the web through at least one calendering nip (20,40) so that the tendencies of curling that arose in the web in the forward drying stage are substantially reduced.

Abstract: A belt conveyer system where along various sections great differences in height must be overcome. A conveyer belt that is initially spread flat is guided in steeply inclined stretches to form a closed hose. To satisfactorily transport, without loss, even difficult-to-handle, fine-particled material, the transition from a steep section into a horizontal section, or even to a discharge station, the steadily opening cross-sectional area is a critical process. To avoid the danger of disruption, a cover belt is provided that extends over the transition zone. The lower run of this cover belt extends into the opening hose cross-section of the conveyer belt, rests directly upon the transported material, and is supported on both sides on the edges of the conveyer belt.

Title: Rapid quantitative analysis of proteins or protein function in complex mixtures
Inventor: AEBERSOLD RUDOLF HANS
IPC: G01N33/58
Filed: 1999-08-25
Granted: 2004-02-26
Abstract: Analytical reagents and mass spectrometry-based methods using these reagents for the rapid, and quantitative analysis of proteins or protein function in mixtures of proteins. The methods employ affinity labeled protein reactive reagents having three portions: an affinity label (A) covalently linked to a protein reactive group (PRG) through a linker group (L). The linker may be differentially isotopically labeled, e.g., by substitution of one or more atoms in the linker with a stable isotope thereof. These reagents allow for the selective isolation of peptide fragments or the products of reaction with a given protein (e.g., products of enzymatic reaction) from complex mixtures. The isolated peptide fragments or reaction products are characteristic of the presence of a protein or the presence of a protein function in those mixtures. Isolated peptides or reaction products are characterized by mass spectrometric (MS) techniques. The reagents also provide for differential isotopic labeling of the isolated peptides or reaction products which facilitates quantitative determination by mass spectrometry of the relative amount of proteins in different samples. The methods of this invention can be used for qualitative and quantitative analysis of global protein expression profiles in cells and tissues, to screen for and identify proteins whose expression level in cells, tissue or biological fluids is affected by a stimulus or by a change in condition or cell state of the cell, tissue or organism from which the sample originated. <IMAGE>

Abstract: ABSTRACT      An engine speed control apparatus capable of controlling the idling speed of an engine without entailing abnormal rise or fall of engine speed while the engine is in operation in an idling mode.  An engine speed control apparatus comprises a switch means which assumes a predetermined state when the degree of opening of a throttle valve is in a range from a fully closed state to a predetermined value of opening, an idling mode detecting means which detects an idling mode of the engine on the basis of the operating conditions of the engine which include the output signal of the switch means, and a control means which controls the air intake rate of the engine in a feed-back control mode while the engine is operating in an idling mode so that the engine speed coincides with a target speed, wherein the idling mode detecting means detects the idling mode of the engine by detecting the throttle valve which is in a predetermined range of throttle opening narrower than said predetermined range from the fully closed state to the predetermine value.

Title: Method and apparatus for marking letter mail
Inventor: SANSONE RONALD P
IPC: B07C3/18
Filed: 1990-12-28
Granted: 2001-12-04
Abstract: This invention relates to methods and apparatus for marking letter mail or mail pieces to provide a fast and convenient way of determining zip code breaks in a stack of letter mail. The mail pieces have marks printed on the edges thereof indicative of the continuity of the same zip codes thereon. The marks are visible when the mail pieces are stacked. Adjacent envelopes with the same zip codes will have an edge mark at the same location, but upon the zip code changing, the next envelope will have a mark placed at a different location.      Numbers in sequence can be printed on each of the letters so that a mail clerk can inspect the last letter within a zip code group to determine if there is a sufficient number of mail pieces within that zip code set to allow a postal discount.      In an alternative embodiment, the markings on the side of the mail pieces are printed in a pattern so as to form numbers when a stack is viewed from the side. In addition to forming numbers, a pattern line can extend between the numbers. This allows a postal clerk to look at a stack of envelopes in a tray and from the side markings not only determine which of these envelopes are in the same zip code set, but also there would be an indication of the last number of the zip code.

Title: Insulated window assembly with resilient internal muntin bars and method of making same
Inventor: BAIER BRUCE A
IPC: E06B3/66
Filed: 1991-08-28
Granted: 1995-09-19
Abstract: A true divided look is provided in an insulated two-pane window assembly through use of a resilient silicone foam internal muntin bar grid which is low in thermal conductivity to limit heat transfer between panes and is high in flexibility to allow for bending when forming curved shapes.  The grid is secured by adhesive on one side to one pane of glass, thereby allowing natural expansion and contraction of the glass panes.  The resilient muntin bar includes the resilient muntin bar being U-shaped with a base from which legs extend which are compressible and adapted to move laterally in response to pressure from the panes due to changing thermal conditions or bonding of external wooden muntin bars to the panes.  Movement of the panes toward each other would be limited by bottoming out against the base of the resilient muntin bar.
