Abstract: A lifting gear, in particular a telescopic boom crane, including at least one boom, a boom adjustment unit including at least one hydraulic actuator for adjusting the boom, and a control device for controlling the movement of the hydraulic actuator, the control device being provided with a displacement controller having at least one pump for adjusting the hydraulic actuator.

Abstract: The invention relates to a control arrangement for vehicles having a hydrostatic auxiliary drive for one or more axles, in particular for motor graders, having a drive engine, driven rear wheels coupled to the drive engine, further wheels which can be activated by associated hydraulic motors and can be operated by a hydraulic pump coupled to the drive engine and which has an adjustable feed volume, wherein each wheel is connected to a hydraulic motor without a clutch. The hydraulic pump and the hydraulic motors can be activated electrically and adjusted in a continuously variable fashion and the hydraulic pump is connected directly, without valves, to the hydraulic motors in parallel by hydraulic lines. The control device controls the respective displacement volume of the hydraulic motors only as a function of the rotational speed signals of the sensors.

Abstract: The present invention relates to an apparatus for the additive production of components. The apparatus comprises an additive production head having an extrusion nozzle and a plasma source arranged around the extrusion nozzle or integrated into the extrusion nozzle for the generation of plasma. The present invention additionally relates to a method for the additive production of components. A plasma is generated in the method with the aid of a plasma source arranged around an extrusion nozzle of an additive production head or integrated into the extrusion nozzle. A material is furthermore melted, pressed through the extrusion nozzle, and deposited in layers. In addition, a treatment by the plasma takes place in which a surface on which the material is deposited in layers is treated with the plasma before the deposition and/or the material is treated with the plasma before, during, and/or after the deposition.

Abstract: The invention relates to an electrically controlled interference colour filter comprising at least two transparent electrodes, at least one nematic liquid crystal layer and alignment layers for alignment of the liquid crystals. When an electrical field is applied the liquid crystals can be realigned and thus the transmission wavelength range of the interference colour filter can be shifted.

Abstract: An object with reflection-reducing coating includes a substrate and a coating arranged on the substrate.

Abstract: A measuring device for quantitative determination of optical characteristic values for detecting photo- and/or electrochemical decomposition reactions taking place on surfaces of photocatalytically active substrates.

Abstract: A method for producing layer systems on substrates includes irradiating a first vacuum coating source with an irradiating source. The first vacuum coating source includes a first layer material that is dissolved in a solvent. A second vacuum coating source is applied to the substrate via a chemical vapor deposition process. In this way, novel layer systems and mixed layers, in particular mixed layers of polymers and metals or metal oxides can be applied.

Abstract: The present invention relates to a process for the vacuum-based deposition of a titanium oxide layer from the gas phase on a substrate, wherein deposition is carried out from a source containing titanium oxide at a deposition rate of less than 25 nm/s in an oxygen-containing atmosphere and at a substrate temperature of less than 500° C. and, after deposition, the coated substrate is heat treated for a period of at least 30 minutes in an oxygen-containing atmosphere at temperatures in the range from 200° C. to 1000° C.
