摘要:
The method of making borosilicate glass with a surface having reactive SiOH groups on it includes preparing a borosilicate glass melt and dissolving at least 30 mMol per liter of water in the borosilicate glass melt. The borosilicate glass contains from 70 to 87 percent by weight, SiO2; from 7 to 15 percent by weight, B2O3; from 0 to 8 percent by weight, Al2O3; from 0 to 8 percent by weight, Na2O and from 0 to 8 percent by weight of K2O. The borosilicate glass with the easily modified reactive surface can be used as a substrate for chemically covalent immobilization of reactive substances.

摘要:
The present invention comprises a method for the control of a drive of a crane, in particular of a slewing gear and/or of a luffing mechanism, wherein a desired movement of the boom tip serves as an input value on the basis of which a control parameter for the control of the drive is calculated, characterized in that the oscillation dynamics of the system comprising the drive and the crane structure are taken into account in the calculation of the control parameter to reduce natural oscillations. The present invention furthermore comprises a method for the control of a hoisting gear of a crane, wherein a desired hoisting movement of the load serves as an input value on the basis of which a control parameter for the control of the drive is calculated.
摘要:
A graphical application system, with a surface spattering device, with at least one nozzle for expelling a spattering material onto a target surface, a nozzle control mechanism controls expelling of the nozzle. A spatial referencing unit references the spattering device in space and a computation means automatically controls the nozzle according to information from the spatial referencing unit and according to predefined desired spattering data as a digital image or a CAD-model of a desired pattern to be spattered onto the target surface. A communication means for establishing a communication link from the spatial referencing unit to the computation means to supply the position and orientation to the computation means. The spatial referencing unit is located remote from the spattering device and comprises at least two optical 2D cameras arranged with a stereobasis, for determining the position and orientation of images taken by the cameras.
