Abstract: The invention discloses a preparation method and a production device for producing a recycled fiber spinning solution with using a solvent, which comprises two or more vertical wiped film evaporators (3, 4, . . . ) connected with a single horizontal cylindrical kneading reactor. The aqueous mixture of cellulose and solvent and auxiliary agent is prepared into a spinnable cellulose spinning dope, which is characterized by injecting the material mixture into two or more vertical wiped film evaporators and a horizontal cylindrical kneading reactor, each unit is preferably equipped with a separate condensing system, and the vacuum system can be separately configured to share a vacuum system.

Abstract: A return stage of a radial turbo fluid energy machine, in particular of a radial turbo compressor, having an axis of rotation, the return stage has an annular flow channel for feeding a flowing process fluid from a flow opening of a first impeller to a flow opening of a second impeller arranged downstream. In order to increase efficiency, the flow channel is defined by bounding surface areas, of which at least one certain rough area extending in the circumferential direction has a surface roughness that is increased in relation to the her areas.

Abstract: A volute for a radial turbomachine is proposed. The turbomachine includes a radial compressor or a radial turbine. The volute is in particular for a radial compressor. The volute has a substantially annular cavity which is delimited at least by a first radial side surface. At least one substantially annularly circumferential groove is formed in the side surface.

Abstract: Adhesive film, useful in a punching process, having a support and at least one layer of adhesive substance, the adhesive substance having two or more lower layers at least one of which is in a mechanically tensioned state.

Abstract: Method for the solvent-free production of acrylate adhesive masses, which comprises (a) continuously coating a mixture, containing one or more photoinitiators and a monomer mixture comprising (i) 70 to 100% by weight compounds selected from the group consisting of (meth)acrylic acid and the derivatives thereof in accordance with the formula where R1 is H or CH3 and R2 is an alkyl chain having 2 to 20 carbon atoms; (ii) 0 to 30% by weight of olefinically unsaturated monomers having functional groups; and (iii) optionally additional components, or a prepolymer of said monomer mixture on a process carrier; b) polymerizing the coated mixture by applying radiation to the coated sections of the process carrier using visible or ultraviolet light; (c) separating the polymer product from the process carrier and forming the polymer product; (d) transferring the polymer product into a mixing device; (e) mixing the polymer product with additional components in a mixing device; and (f) further processing the polymer p

Abstract: Process for producing a composite of catalyst material and solid electrolyte membrane for an electrochemical cell in which a catalyst material is first applied to a repellent carrier which has at least one release layer of a condensation- or radiation-crosslinked organopolysiloxane, and is then laminated at least partly onto at least one side of a membrane.

Abstract: Production of vinyl polymers by the polymerization of vinyl monomers in a planetary gear extruder.

Abstract: Apparatus far equilibrating differences between flow rates into and out of closed pipeline systems, which apparatus includes a tank having a supply line and a discharge unit, with a displaceable plate; the supply being fed to the tank through the displaceable plate, the discharge from the tank being through an outlet at the bottom of the tank and the plate moving upwards or downwards to automatically change the volume of the tank in accordance with differences between the supply rate and the discharge rate.

Abstract: A process for producing products in web form comprising at least two layers, in which a composition emerging from an applicator is applied as a layer to a substrate in web form which is guided on a transport means, the application taking place with application of electrostatic charges, and in which the substrate coated with the composition is electrostatically neutralized before departing the applicator, the transport means being provided with an electrically insulating coating.

Abstract: The invention relates to a process for coating web substrates (10), the substrate (10) being coated over at least part of its area with a first adhesive (12) and thereafter the substrate (10) coated with the first adhesive (12) being coated over at least part of its area with at least one second, further adhesive (14). Provision is made for the first adhesive (12) to be still wet or not yet cured when it is coated with the further adhesive (14).

Abstract: Short deoxyribonucleic acid molecules that are partially single-stranded, dumbbell-shaped, and covalently closed, which contain one or more unmethylated cytosine guanosine motif (CpG motif) and exhibit immunomodifying effects. Such molecules can be used for immunostimulation applications in humans or vertebrates.

Abstract: An apparatus for the equilibration of the throughput of, in particular, highly viscous fluids in closed pipeline systems, comprising a supply line, a tank, a plate which is displaceable in the tank and a discharge unit, characterized in that the fluids are fed to the tank through the supply line, which tank is closed at the inflow opening by a displaceable plate, which is sealed against the inside walls of the tank and bears the supply line, and at the outflow opening by a base and a delivery unit attached thereto, closed in such a way that the volume changes automatically as a result of the difference in the throughputs at the inflow and outflow and the resultant displacement of the plate.
