Abstract: The adhesive application station (14) for binding stacked printed products (10) by means of a liquid or liquefiable adhesive (52) comprises an application station (14) with an adhesive discharge system (15). This system consists substantially of an application head (12) for the adhesive (52) with a slip surface (16) for the printed products (10), and an application nozzle (42) extending over the entire width (g) of the slip surface (16) with at least one outlet opening (20) for the adhesive, an adhesive reservoir (50) and means for generating a pressure on adhesive application. The adhesive discharge system (15) also comprises immediately adjacent to the outlet opening(s) (20), a metering device (44, 45) which can be sealed manually and/or electronically controlled by an actuator (130). This metering device (44, 45) forms with the adhesive reservoir (50) and an integral accumulator (54) a pressure compensation system.
Abstract: Proteolytically stable small molecule ?-turn peptidomimetic compounds have been identified as agonists or antagonists of neurotrophin receptors, such as TrkA. A compound of particular interest binds the immunoglobulin-like C2 region of the extracellular domain of TrkA, competes the binding of another TrkA ligand, affords selective trophic protection to TrkA-expressing cell lines and neuronal primary cultures, and induces the differentiation of primary neuronal cultures. The small ?-turn peptidomimetic compounds of the invention can activate a tyrosine kinase neurotrophin receptor that normally binds a relatively large protein ligand. Such compounds that bind the extracellular domain of Trk receptors are useful pharmacological agents to address disorders where Trk receptors play a role, by targeting populations selectively.

The bill has at least a distinctive portion detectable by the sensor 16. The paper 50 has its width W substantially same as the width of the bill. The characteristic pattern 51 of the paper 50 is formed on substantially same position in width W as that of the distinctive portion in the bill. The paper 50 is inserted into the validator 10 to detect the characteristic pattern 51 of the paper 50 by the sensor 16 for discrimination of the paper 50 by the validator 10.
Abstract: A method and a device for the continuous, single-step production of a homogenous solution of cellulose in hydrous aminoxides on the basis of cellulose and aqueous aminooxides, preferably N-methylmorpholino-N-oxide (NMMO), at temperatures in the range of from 50 to 130° C. under a vacuum and water evaporation. The cellulose and the NMMO are dosed separately to the device, mixed while sheared, the water is evaporated until the mixture is dissolved, the solution is homogenized and directly fed to the consumer via screw conveyors, pumps and filters.

Abstract: The present invention relates to a zinc-diffused nickel alloy coating for corrosion and heat protection and to a method for forming such a coating. The coating method broadly comprises the steps of forming a plain nickel or nickel alloy coating layer on a substrate, applying a layer of zinc over the nickel or nickel alloy coating layer, and thermally diffusing the zinc into the nickel alloy coating layer. The coating method may further comprise immersing the coated substrate in a phosphated trivalent chromium conversion solution either before or after the diffusing step. The substrate may be a component used in a gas turbine engine, which component is formed from a steel material.
Abstract: A main engine mounted auxiliary power unit comprises an auxiliary power unit integrated with a primary gas turbine engine into a single power plant suited for aircraft applications. The auxiliary power unit can be mounted within an engine core compartment of the main engine or at the main engine aft center body. The integration of the auxiliary power unit provides for installation and certification cost savings to the airframer by eliminating the need for mounting an auxiliary power unit to the tail section of the aircraft.

Abstract: An automatic welding machine for planar plastic materials, such as sealing sheets, tarpaulins or films, the chassis, in the welding position, in addition to being carried by the driving unit and the pressure device, also being carried by a rigid guide wheel, preferably in the front region of the chassis. With respect to a pressure roller running essentially on the welded overlap region, the guide wheel is arranged in such a way that, during the welding, it runs along the bottom plastic material parallel to the edge of the top plastic material. In addition, the guide wheel has a narrow running surface. During the welding, the guide wheel runs along the edge of the overlapping plastic material and the pressure roller runs essentially on the weld region. Due to this configuration, the automatic welding machine can follow the edge in such a way as to keep to the track, so that guidance by the operator or frequent corrections of the welding direction are not necessary.
Abstract: Disclosed herein is an apparatus for generating a parallel beam with a high flux. The apparatus of the present invention includes a light source, a first mirror and a second mirror. The light source is positioned at a first focal point of a first ellipse. The first mirror is positioned on the first ellipse to reflect a beam emitted by the light source, and concavely shaped to conform to a section of the first ellipse. The second mirror is positioned across a path of the beam reflected by the first mirror, and convexly shaped to conform to a section of a second ellipse so that an angle formed by two tangent lines passing through each pair of incident points of neighboring rays incident upon the second mirror, respectively, is half of an angle formed by two tangent lines passing through each pair of incident points of neighboring rays incident upon the first mirror, respectively.
