Abstract: The present application relates to a novel and improved process for preparing the compound 2-{4-[2-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-3,5-dicyano-6-(pyrrolidin-1-yl)pyridin-4-yl]phenoxy}ethyl-L-alanyl L-alaninate monohydrochloride of the formula (I) to novel precursors for its preparation, and to the preparation and use of crystal modification I of 2-{4-[2-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-3,5-dicyano-6-(pyrrolidin-1-yl)pyridin-4-yl]phenoxy}-ethyl-L-alanyl L-alaninate monohydrochloride of the formula (I).

Abstract: An apparatus for adjusting a surface of an aircraft model includes, but is not limited to a first linear adjustment unit with a first retaining body that is movable along a first axis, a second linear adjustment unit with a second retaining body that is movable along a second axis, and an angle adjustment unit. The second linear adjustment unit is arranged on the first retaining body, and the angle adjustment unit is arranged on the second retaining body and is configured to adjust and lock an angle between an attachment surface and a retaining surface. Consequently, precise positioning of surfaces of a wind-tunnel aircraft model does not require specially manufactured and individually adapted fittings for each setting position to be moved to.

Abstract: The invention relates to a monochromator mirror for the EUV-spectral range, provided with a layer arrangement placed on a substrate, comprising a periodic sequence of two individual layers (A, B) made of different material forming a period having a thickness d in the form of a spacer-layer or an absorber-layer, whereby the reflectivity of the second or a higher Bragg-order is used. Said thickness d has a dimensional deviation of a maximum of 3% and the ratio of the layer thickness of the absorber-layer to the period thickness is smaller than the ratio of 0.8 of the used order of the Bragg-Reflexion.

Abstract: The invention relates to a contactless safety switch for detecting the shut position of a shutting part in relation to a closeable part, with a switch unit, supplied with current by an electrical supply source on one of the parts and with a trip arranged on the other part and comprising a magnet. In this case, the switch unit comprises a transmission circuit with a clock-signal generator and with a transmission coil, a receiver circuit connected to an evaluation unit and having at least one receiver coil and also a Hall sensor responding to the magnet, and the trip comprises a trip coil which is capable, in the shut position, of being excited inductively by the transmission coil and exciting the receiver coil, while, in the shut position, the evaluation unit triggers a clearance path when the Hall sensor is activated via the magnet.

Abstract: A seal comprising two rings is disclosed. A sensor or signal generator is immovably affixed to the polymeric member of one of the rings. In one embodiment, the other of the rings includes a corresponding sensor or signal generator, depending on which of these types of elements is affixed to the first ring, that is immovably affixed to the second ring.

Abstract: A thermostable substrate for flexible circuit boards having excellent flame-resistance, handling, and storage qualities may be produced by treating a substrate of a nonwoven fabric or paper with a flame-resistant, halogen-free polymeric composition. The polymeric composition comprises an aqueous mixture of a copolymerizate of acrylic acid esters and styrene, and an aminoplastic or phenoplastic precondensate to which a mixture of fine-particle red phosphorus and fine-particle ammonium polyphosphate is also added.

Abstract: A flame-resistant cover film for flexible circuit boards having excellent flame-resistance, handling, and storage qualities may be produced by treating an insulating film of a nonwoven polymer fabric with a flame-resistant, halogen-free polymeric adhesive. The polymeric adhesive comprises an aqueous mixture of a copolymerizate of acrylic acid esters and styrene, and an aminoplastic or phenoplastic precondensate to which a mixture of fine-particle red phosphorus and fine-particle ammonium polyphosphate is also added.
