Abstract: A process in preparing a high absorption fluff pulp which can be shredded at a low power consumption to fluff, wherein to the pulp suspension before or on the wire is added ampholytic tensides and/or tensides which are cationic at low pH values and nonionic at high pH values, the pH value being kept sufficiently low for the tensides to be in cationic form, whereupon the pH value is increased to such an extent that the tensides are transferred into the anionic and nonionic form respectively, which pH increase takes place just before the pulp web leaves the wire or before any of the presses or between the last press and the drying section or in the drying section or in connection with the feeding of the pulp into the fluffing machine.

Abstract: Um einzelne Ballengruppen, unabhängig von ihrer sich über die Höhe verteilende ungleichmäßige Dichte mit einer im wesentlichen gleichmäßigen Abtragleistung abzutragen, werden die einzelnen Ballengruppen in drei bis vier Zonen unterteilt, welche eine unterschiedliche Dichte des Fasermaterials aufweisen, z. B. in die Zonen A, B, C und D. Erfindungsgemäß wird das Abtragorgan (5) mit der rotierenden Abtragwalze (6) mit einer relativ großen Abtragtiefe durch die Zone A geführt, während in der Zone B die Abtragtiefe allmählich, d. h. nach jedem Durchgang um einen bestimmten Betrag reduziert wird, bis die gewünschte Abtragtiefe für die Zone C erreicht ist. In dieser letztgenannten Zone werden die Faserflocken mittels einer vorgegebenen Abtragtiefe herausgelöst bis die Zone D erreicht ist, in welcher dann die Abtragtiefe wieder bis und mit der letzten Schicht allmählich vergrößert wird. In der Steuerung ist ein Mikroprozessor vorgesehen, welcher diese gewünschte Anzahl Durchgänge und Abtragtiefen für das Erhalten der genannten Zonen speichert. Die Abtragtiefen und Durchgänge, d.h. also die Aufteilung der einzelnen Zonen, werden nach freier Wahl einprogrammiert und dann entsprechend abgetragen.

Abstract: In a circuit arrangement for energizing the regulation and control device (RS) of a regulated direct voltage converter (GW), a charging capacitor which supplies the regulation and control device (RS) is charged during the starting stage by the input voltage (U1) of the direct voltage converter and during the operating condition by an auxiliary voltage (UH) at the secondary side of the converter (GW). The change-over takes place by means of a threshold value switch (S), which switches off a constant-current source (U1,IC) that can be switched on and off as soon as the voltage at the charging capacitor (C) exceeds by a given amount a reference voltage (Uref). The circuit arrangement exhibits particularly low losses during the operating condition of the direct voltage converter.

Abstract: In a coaxial hose system for a fuel distribution system, a product delivery hose (120) is centrally located within a vapor recovery hose (82), whereby the area between the product and vapor hoses provides a return path for vapors developed at a nozzle during refueling of a vehicle. A venturi pump (64) is located in the product hose (120) line, and operable over a range of flow rate of the fuel through the product hose (120), for sucking fuel back into the product hose (120) from an area of the vapor path where fuel may accumulate due to backflow from the nozzle (128), thereby substantially insuring a clear vapor path and more complete delivery of metered fuel.

Abstract: This disclosure sets forth a variable tensioning system for use in a valve featuring shear seals. In the preferred and illustrated embodiment, a spring system provides loading on the valve element (18) to force that element into engagement with a valve seat (14). A sliding sealing surface is accomplished in this contact. The valve element (18) may be a tapered plug, a sphere or a flat face or plate. Typically, it is a hard member working against a seat (14) supporting a seal surface featuring a sliding shear seal. A specific minimum load is applied to the valve element (18) to accomplish sealing against minimum pressure. The present apparatus incorporates a closed chamber (24) enclosing a slideable piston (31). The piston (31) has a specific cross-­sectional area exposed to fluid pressure of the fluid being controlled by the valve. The piston (31) applies pressure dependent force against the valve element (18). This adds to the force applied to the valve element (18) by a spring means (30), the two forces controllably adding to assure that the seal is sufficiently loaded to perfect a seal up to a specified maximum pressure.

Abstract: A combination composed of a conduit for conveying a fluid medium along a linear path under very high pressure and a choke disposed in the conduit, the conduit having an inner wall and the choke being composed of a restrictor having a restrictor opening which is constricted relative to the cross section of the conduit and a movable needle mounted for movement in the direction of the linear path for constricting or closing the restrictor opening. The conduit is made of a material capable of withstanding the high pressures exerted on the inner wall of the conduit by the flowing medium and the choke is made of a very hard and brittle material which is resistant to wear. The choke further includes a central insert member having an outer tubular part fastened to the inner wall of the conduit, an inner part supporting the needle within the conduit so that fluid medium flowing through the conduit flows around the needle, and a member connecting the inner part to the outer part. The needle is supported by the inner part for movement relative to the inner part parallel to the linear path. The choke further includes a hydraulic drive unit supported by the inner part and forming a unit with the needle. The central insert member is configured and fastened to the inner wall of the conduit so as to offer only slight resistance to flow of the fluid medium past the central insert member.

Abstract: Immobilization of nucleic acids, e.g., DNA and RNA, by contact with a solid support comprising nylon having amide groups that have been derivatized to amidine residues. Derivatization of the nylon support can be accomplished by treatment with an alkylating agent such as a trialkyloxonium salt under anhydrous conditions followed by reaction with an amine. The immobilized nucleic acid is particularly useful as an immobilized probe in hybridization assays to detect specific polynucleotide sequences in a test sample.

Abstract: A fitting formed with a circular flange formed coaxially with a spigot which is formed along its length with a series of frusto-conically shaped, axially spaced apart, sealing rings which are formed attheir enlarged ends with respective annular holding rings. A metallic stiffener tube is received telescopically in the fitting to provide support against radial inward collapse thereof. The spigot may be formed adjacent the flange with an enlarged extremity remote from the flange with a reduced in diameter stress relief nipple. A finishing sleeve is provided for telescopical receipt over a polyethelene pipe fitted over the spigot. Thus the spigot may be inserted into the end of the plastic pipe to expand such pipe to an expanded configuration. The finishing sleeve may then be drawn telescopically over the expanded configuration to press the wall of the polyethelene pipe radially inwardly to compress the polyethelene material between the stiffener tube and finishing collar to flow the pipe wall material radially inwardly into the grooves formed between adjacent ones of the sealing rings to thereby form a plastic coupling completely surrounding the metal stiffener tube to isolate it from soil in which the pipe might be buried. The method includes the steps of severing a leaking section from a plastic pipe and inserting such a double ended fitting as a substitute for the severed section.

Abstract: The invention concerns a process for control of the opening of a power interrupter, especially a transistor, at a determined instant, regardless of the particular characteristics of the interrupter. According to the invention, the emission of the normal closing command (A) of the interrupter is terminated at a determined time interval before the said determined instant, and in its place is emitted an additional closing command (G) with a duration equal to the difference between the said interval and the actual time required by the interrupter to pass from the closed state to the open state. Preferably, the actual time required by the interrupter to change state is determined during its preceding passages from the closed state to the open state.
