Injection mortar for anchoring a fastening element containing a chemical composition that can cure in a curing process, and means for initiating the curing process characterized in that the chemical composition cures when irradiated with electromagnetic radiation, the means for initiating the curing process is formed by a radiation source for electromagnetic radiation, and the radiation source is placed within the anchoring zone.

Injection mortar

The present invention relates to a method for degradation of a phenolic resin-containing material, characterized in that the phenolic resin-containing material is subjected to an aminolysis with a reagent containing at least one amino group, as well as a method for synthesis and degradation of a phenolic resin-containing material, characterized in that the phenolic resin-containing material is created by curing the starting components at a temperature of less than 140&#xb0; C. and is subjected to aminolysis with a reagent containing at least one amino group for the purpose of degradation.

Method of recycling phenol resin-containing materials, especially phenol resin-based fiber composite materials

The invention relates to a chemically degradable cured epoxy resin system containing one or more epoxide resins and one or more curing agents, characterized in that the curing agent contains at least one cyanate, with which the epoxy resin reacts to form an epoxy resin polymer containing cyanurates. The cured epoxy resin system can be recycled by chemically decomposing the cured component epoxy resin system by aminolysis with reactive NH&#x2014; or other amino groups and/or alcoholysis with mono-, di-, or poly functional alcohols.

A processing station automatically manufactures a cable harness containing a plurality of individual lines. The processing station has a support unit for holding a line bundle containing the individual lines with a predefined, even branched, routing, and a processing unit for the automated fixing of the individual lines of the line bundle to one another. The processing unit has a fixing unit, which is configured for the automated application of a fixing agent to the line bundle. A manipulator is provided for moving the processing unit relative to the line bundle.

Synthesis of novel monomers containing the trifluorovinylidene group and the cyanato group and polymers thereof

The present invention is directed to optical waveguides or waveguide systems, comprising at least (a) a first material which is a poly(perfluorocyclobutane), and in direct contact to this material, (b) a second material which is a polycyanate resin made from at least one aromatic difunctional cyanate of formula (I) wherein Rto Rare independently from each other hydrogen, optionally substituted C-Calkyl, C-Ccycloalkyl, C-Calkoxy, halogen, phenyl or phenoxy, the alkyl or aryl groups being unfluorinated, partly fluorinated or fully fluorinated with the proviso that (I) carries at least 1 fluorine atom, and Z is a chemical bond, SO, CFCH, CHF, CH(CH), isopropylene, hexafluoroisopropylene, n- or iso-C-Calkylene which may be partly or fully fluorinated, O, NRwhereby Ris hydrogen or C-Calkyl, N&#x2550;N, CH&#x2550;CH, C(O)O, CH&#x2550;N, CH&#x2550;N&#x2014;N&#x2550;CH, alkyloxyalkylene having 1 to 8 carbon atoms, S, or Si(CH)optionally in mixture with other components. Preferably, both the first and the second materials are in the form of a thin layer, the layers directly adhered to each other. Either the waveguide can be made from the first material and at least one of the buffer layer and the cladding layer can be made from the second material, or vice versa.

The present invention relates in general to optical waveguide devices, which preferably are planar, e.g., optical arrayed waveguide gratings (AWGs), multiplexers/demultiplexers, optical add/drop multiplexers and the like. More particularly, the present invention provides integrated optical waveguide devices having central wavelengths (or channel wavelengths) which are temperature insensitive in that they do not or do almost not shift upon temperature variations in the environment. Such devices are also called athermalized or athermal devices. Preferably, most or all parts of such devices including waveguides, cladding material and the substrate itself consist of organic polymeric materials. The devices of the invention substantially remedy the problems encountered with the limitations and disadvantages of common devices as known in the prior art.

Temperature insensitive optical waveguide device

The present invention is directed to wave guide systems or structures or parts thereof, characterized in that they consist of or comprise a resin composed of at least one polycyanate copolymer, obtainable by copolymerization of at least one specific difunctional cyanate with at least one monocyanate of the formula N&equiv;&mdash;C&mdash;O&mdash;R, wherein R is a straight or branched non-aromatic hydrocarbon radical or a non-aromatic hydrocarbon radical comprising a cyclic structure, the radical having the formula C(R&prime;) &mdash;CFR&Prime; wherein each R&prime; is, independently from the other, hydrogen or fluorine or an optionally substituted, preferably fluorinated alkyl or alkenyl group, and each of R&Prime; may independently be defined as R&prime; or may have an arylic structure.
