Abstract: Method for cleaning and/or deodorizing a toilet bowl or urinal. In one embodiment, the method involves directly applying an agent to the toilet bowl or urinal. The agent adheres to the toilet bowl or urinal and can be flushed away only after a relatively large number of flushing operations. The agent includes fillers from the group of surfactants and also an adhesion promoter. The viscosity of the agent is at least 30 Pas, measured using a Haake viscometer, plate/plate system, plate diameter 10 mm, at a shear gradient of 2.62 s?1 and 20° C. and the agent is so sticky that it can serve to attach bar-shaped agents to the toilet bowl or urinal, wherein the concentration of the surfactants in the case of an adhesion promoter from the group of polvalkyleneimines is between 7 and 60% by weight. The agent may have associated with it one or more bar-shaped compositions.

Abstract: The invention relates to a self-propelled civil engineering machine, and in particular to a slipform paver, road paver or road milling machine, and to a method of controlling a self-propelled civil engineering machine. The civil engineering machine according to the invention has a control unit 7 which has means for determining data which defines the position and/or orientation of a reference point R on the civil engineering machine in relation to a reference system (X, Y, Z) independent of the position and orientation of the civil engineering machine. The reference system (X, Y, Z) independent of the machine-related reference system (x, y, z) may be selected as desired, and there is thus no need for the positions of various reference points to be plotted on the ground.

Abstract: The invention relates to an optical guidance system for a laying engine for producing a concrete or asphalt top layer along a given path (6), wherein the laying engine comprises a first unit (1), such as a distributor for distributing the material and a second unit (2), such as a finisher for smoothing the material. The first and second unit are driven independently of each other and may be driven in formation. According to the invention, the optical guidance system comprises at least one transmitter component (3), one receiver component (5) and one computer component (19) for providing control instructions, relating for example to the direction of travel of the first or second unit. The transmitter component (3) is to be provided on the second unit (2) ad designed to emit optical reference beams (4).

Abstract: A method for producing at least one product stream containing hydrogen from a feedstock containing glycerol and a device for performing the method is disclosed. By separation of unwanted substances and pyrolysis of glycerol, an intermediate product is obtained from the feedstock containing glycerol and is then converted into a crude synthesis gas containing hydrogen and carbon monoxide by steam reforming in an externally heated steam reforming reactor.

Abstract: The invention provides a process for hydrogenating streams in plants for producing alkenes by catalytic dehydrogenation of light alkanes, and also an apparatus for carrying out the process. The entire hydrocarbon stream to the dehydrogenation reactor, consisting of fresh and recycled alkane, is subjected upstream of the dehydrogenation reactor to a full hydrogenation of all unsaturated hydrocarbons present therein. This drastically reduces coke formation in the dehydrogenation reactor. The energy demand for the preheating of the reactant stream to reaction temperature is reduced since the energy released in the exothermic hydrogenation remains virtually fully in the hydrocarbon stream.
