Abstract: A controller for an industrial automation system includes a main module having a housing, which can be fitted onto a DIN rail via a base, at least two printed circuit boards arranged in the housing, and a heat sink also arranged in the housing and connected with the base. One of the circuit boards is a backplane bus printed circuit board, which provides a backplane bus, and the other is a main printed circuit board. The heat sink is attached to at least one of the printed circuit board to cool its components.

Abstract: A process and a kit-of-parts for dyeing keratinous material, such as human hair, are provided. An exemplary process for dyeing keratinous material includes applying an agent (a) to the keratinous material. Agent (a) includes (a1) at least one organic silicon compound selected from the group consisting of silanes having one, two or three silicon atoms, and (a2) at least one first colorant compound comprising at least one pigment based on a lamellar substrate platelet. The method further includes applying an agent (b) to the keratinous material. Agent (b) includes (b1) at least one film-forming polymer, and (b2) at least one second colorant compound selected from the group consisting of pigments and/or direct dyes.

Abstract: Processes for dyeing keratinous material, in particular human hair, are provided including the following steps: applying an agent (a) to the keratinous material, wherein the agent (a) includes: (a1) at least one organic silicon compound selected from the group of silanes having one, two or three silicon atoms, and (a2) at least one coloring compound including at least one effect pigment which includes ?) a substrate platelet and ?) a coating, wherein the coating has at least one layer which is (i) a metal oxide and/or metal oxide hydrate and (ii) a coloring compound from the group of pigments, and applying an agent (b) to the keratinous material, wherein the agent (b) comprises: (b1) at least one sealing reagent.

Abstract: A connection terminal for connecting a conductor is formed as a direct plug-in terminal and includes a clamping spring arranged in a housing. The clamping spring includes a resilient clamping leg which can move into an open and locking position by pressing down an actuating device. The housing contains a conductor insertion channel for insertion of the conductor into a clamping point between the free end of the clamping leg and a busbar. The actuating device includes a pressing element and a pivoting element which interacts with the pressing element at least when the clamping point is being opened. At least one release device is provided for releasing the locking state of the clamping leg of the clamping spring. The release device is designed in such a way that the locking position can be released again by the action of the conductor on the release device when it is inserted, wherein the pivoting element acts on the pressing element and the pressing element acts on the clamping leg.

Abstract: A cold-stable NCO-containing prepolymer obtainable from the reaction of an isocyanate-reactive component comprising polyether carbonate polyols having an isocyanate component comprising methylene diphenyl diisocyanate (MDI) with high contents of 4,4?-MDI, a method for the preparation thereof, and the use thereof in one- or two-component systems for foams, elastomers, adhesives and sealants provided.

Abstract: In a method for the 3D-printing of hydrous mineral binder compositions, an aqueous accelerator is mixed with the binder composition in a continuous mixer. The method is very robust and makes it possible to quickly print even large moulded bodies having a uniform aesthetic surface and very good strength development properties.

Abstract: A method for producing a prepolymer for the production of an integral polyurethane foam is provided. The prepolymer is or can be obtained by reaction of a composition that contains the following components: component A containing a polyoxymethylene-polyoxyalkylene block copolymer having a hydroxyl number of 20 mg KOH/g to 200 mg KOH/g as component Al, component B containing di- and/or polyisocyanates with an NCO content of 15 to 45 wt.-% relative to component B, 0.04 to 1.0 wt.-%, relative to the composition, a proton acid as component C, and optionally a component D that contains auxiliary agents, at a characteristic number of 450 to 850. The invention further relates to the prepolymer obtained by the method, to an integral polyurethane foam based on the prepolymer, and to the use thereof.
