Abstract: The invention relates to compounds based on merocyanines with the general formulas I and/or II, where n=0 or an integer from 1 to 3, X=O or S and the residues R1 to R12 are the same or different and signify in particular hydrogen or various organic residues, without or with functional groups, and R2 incorporates an amine function. The compounds in accordance with the invention are suitable as fluorescent dyes (fluorophores) for used in optical determination and demonstration methods, in particular those employing fluorescence, for example in medicine, pharmacology and the biological, materials and environmental sciences. They are characterized by high photostability and long storage life, and exhibit a high fluorescence quantum yield. Excitation causing them to emit light can be achieved in a simple manner, by white-light sources or by laser irradiation in the UV, visible or NIR spectral region.

Abstract: A means for influencing the temperature of flowable media, especially of lubricants found in a lubricant system, having a line through which the medium flows and at least one element (11) which is assigned to the line section (1, 5) for influencing the temperature and which can be activated by supplying energy, characterized in that at least one element (11) is located within the line section (1, 5) in the flow path of the medium and that the wall of the line section (1, 5) has a connecting means (9) for supplying energy to at least one element (11) located in the line section (1, 5).

Abstract: A means for delivery of flowable media, especially of lubricants, with a pump (1) which can be driven by a motor and which forms a component of a line system is characterized in that at least one heating element (21) which can be activated by energy supply is located outside of the housing (3) of the pump (1) in a position which enables heat transfer to the housing (3).

The compounds are diasteromeric cyanines with high hydrophilicity and other desirable properties.

Abstract: The invention is used in the fields of chemistry and relates to hardenable materials which can be used for producing lacquers. The aim of the invention is to provide materials which harden at low temperatures in the same amount of time as the others. This is achieved by using hardenable materials containing uretdione groups and containing (A) a binding agent constituent, whereby this component either (A1) does not contain carboxyl groups, or (A2) the concentration of carboxyl groups is less than that of the catalyst (C) or (A3) in the case of a high level of concentration, a quantity of a reactive agent is added. The hardenable materials also contain (B) a polyaddition compound which comprises uretdione groups, and (C) at least one Lewis acid catalyst.

Abstract: The invention relates to fluorescent dyes (fluorophores) based on polymethines for use in optical measurement and detection procedures, in particular those employing fluorescence, for example in medicine, in pharmacology and in the biological, materials and environmental sciences. The objective was to create fluorophores based on polymethines that have a large Stokes shift, high photostability, long storage life and a high fluorescent quantum yield, and that can be excited in the simplest possible manner by white-light sources or laser radiation in the UV, visible or NIR spectral region.

Abstract: The disclosure is directed to so-called laser-compatible NIR marker dyes based on polymethines for use in optical, in particular, fluorescence optical determination and detection methods, for example, in the fields of medicine, pharmaceutics and in the areas of life science, materials science and environmental science. The disclosure further discusses the aim of the invention which was to create NIR marker dyes based on polymethine which have a high degree of photostability and stability in storage as well as a high fluorescent yield and which can be excited to fluorescence in the easiest possible manner by means of laser radiation in the visible or NIR spectral range, particularly with light of an argon, helium/neon, or diode laser. Dyes based on polymethine of general formula (I) are used.

Abstract: A fluid cooling device has a cooler, filter and pump combined in a building unit. Fluid conveyed by the pump can be filtered in a fluid circuit by the filter and can be cooled in the circuit by the cooler. The filter is provided with at least one filter element that can be exchanged when the filter is clogged. A controllable unit is provided in the fluid circuit for exchanging the filter element. The filter can be separated from the pump by the controllable unit in such a way that the cooler is still supplied with the fluid to be cooled. The filter element can be exchanged without entailing further difficulties, even when the downstream supply of lubricating oil is not stopped.
