Abstract:
A process for the gas-phase trimerization of formaldehyde to give trioxane using solid phosphoric acid catalysts. Particularly suitable catalysts for this process are SPA catalysts (solid phosphorous acid), for example “silicon phosphates”. The main advantage of this catalyst system is its simple and inexpensive production and ready availability and also, in particular, its improved long-term stability compared to the few previously described catalysts which are mostly based on supported heteropolyacids.
Abstract:
A method for processing an amine-based solvent contaminated by the introduction of sulfur oxides is provided. A potassium compound is introduced into a contaminated solvent, and the contaminated solvent is cooled so that a solubility of a potassium sulfate becomes less than a specified concentration of potassium sulfate. Further, an oxidizing agent is introduced into the contaminated solvent so that a potassium sulfite is oxidized to potassium sulfate. The potassium sulfate is filtered out, wherein a prepared solvent is formed. Further, a device for processing an amine-based, sulfur oxide-contaminated solvent is provided.

Abstract:
A method and an arrangement for optimizing the image quality of movable subjects imaged with a microscope system are proposed. The microscope system encompasses at least one objective that defines an image window. Motions of the subjects being observed are captured in the image frame. A computer system, having a means for determining a respective displacement vector field from a comparison of the respective pixels of two chronologically successive images, generates a trajectory from the synopsis of the displacement vector field of all the acquired images. A means for applying an operation to the image data along a trajectory is also provided.
Abstract:
This invention comprises a method, a software, and a microscope system for monitoring and controlling information loss. The observation of information that is not present and the comparison of ideal loss to actual loss generates an explanatory component by means of a rule set. The user is instructed by the microscope system in an appropriate manner, for example by means of a display, to undertake actions that remove the defects.
Abstract:
The method and the system simplify moving interactions by means of virtual reference subjects and flux-based coordinate transformations in order to generate a changeable frame of reference.
Abstract:
A microscope system (4) for the observation of dynamic processes comprises a microscope (50) having at least one detector (19), and a computer (34). A buffer memory (54) precedes a comparator (58) that compares image contents of at least two successive image frames (56k and 56k+1). Depending on the result obtained from the comparator (58), the image frames are stored in different segments of a data structure (66) that is provided.

Abstract:
A system and a method for setting a fluorescence spectrum measurement system for microscopy is disclosed. Using illuminating light (3) from at least one laser that emits light of one wavelength, a continuous wavelength region is generated. Dyes are stored, with the pertinent excitation and emission spectra, in a database of a computer system (23). For each dye present in the specimen (15), a band of the illuminating light (3) and a band of the detected light (17) are calculated, the excitation and emission spectra read out from the database being employed. Setting of the calculated band in the illuminating light and in the detected band [sic] is performed on the basis of the calculation. Lastly, data acquisition is accomplished with the spectral microscope (100).

Abstract:
A method for user training for a scanning microscope makes possible rapid setting of a scanning microscope with little specimen impact. It is possible to acquire an entire spectrum of a specimen. This specimen can be retrieved from the memory of the computer system for training purposes. The user can then make changes in the setting capabilities displayed to him on the user interface and assess the result thereof, also on the user interface. This can be done without time pressure until the user is satisfied with the result displayed on the user interface.
