Abstract: The present invention relates to heteroleptic complexes comprising a phenylimidazole or phenyltriazole unit bonded via a carbene bond to a central metal atom, and phenylimidazole ligands attached via a nitrogen-metal bond to the central atom, to OLEDs which comprise such heteroleptic complexes, to light-emitting layers comprising at least one such heteroleptic complex, to a device selected from the group consisting of illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED, to the use of such a heteroleptic complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge blocker.

Abstract: A method and system for inspecting a rail profile include using ultrasonic phased arrays. Determined anomalies, such as material flaws like volumetric defects and cracks, in a fluid-immersed rail profile are detected by employing one or more phased array probes located proximate the rail profile. Electronic delays and beam steering and focusing can be employed to tailor the inspection to the rail geometry.

Abstract: An inspection arrangement and an associated method for inspecting an elongate object. The arrangement includes a housing providing an interior space. The housing has an entrance and exit that are aligned. The arrangement includes a plurality of ultrasonic sensor arrays disposed to direct ultrasonic sensory pluses. Each sensor array has a plurality of ultrasonic sensors with each ultrasonic sensor positioned to direct a respective ultrasonic sensory pulse in a respective direction. The arrangement includes a fluid delivery device that delivers a coupling fluid into the interior space. The coupling fluid transmits the ultrasonic sensory pluses to the elongate object. The arrangement includes a plurality of redirecting elements associated with the plurality of ultrasonic sensor arrays. Each redirecting element is positioned such that ultrasonic sensory pluses from the respective ultrasonic sensor array proceed through the respective redirecting element and are redirected along a different direction.

Abstract: The invention relates to an irradiation unit for the UV irradiation of particularly web-shaped substrates, comprising a housing (10), a tubular UV lamp (12), arranged therein and a reflector arrangement (14), running along the UV lamp (12). According to the invention, a simple exchangeability may be achieved, whereby the reflector arrangement comprises a support profile (22), retained in the housing (10) and a reflector profile (24), embodied as a shape-retaining molded piece which may be detachably connected thereto.

Abstract: A connector system for a rod-shaped two-ended gas discharge lamp (12) with bases (20) disposed on the connector ends (16) of the discharge lamp (12) and with insert sockets (22) for receiving the bases (20) in a lamp housing (14). Each base (20) is provided with a contact pin (26) linked with a lamp electrode (36) with an insulating cylinder (28) surrounding the contact pin (26) while leaving a lateral connector opening (46) free. Each insert socket (22) is provided with a contact element (58) that can be detachably engaged with the corresponding contact pin (26) through the connector opening (46) of the pertaining base (20) and can be impinged upon with a high voltage. The insert socket is further provided with an insulating body (60) that carries the contact element (58) and covers the connector opening (46) in the connected state.

Abstract: The invention relates to an irradiating device, especially for irradiating with ultraviolet light substrates which are provided with a coating that can be cured using ultraviolet light. The inventive device comprises a longitudinally extending radiation source (12) which is provided for emitting ultraviolet and/or visible electromagnetic radiation, which is arranged in a housing (10) between a reflector (18) and a housing opening (14) that can be aligned with an object (16) to be irradiated, and which is preferably configured as a tubular mercury discharge lamp. The inventive device also comprises a cooling system (20) for dissipating the waste heat generated by the radiation source (12). The aim of the invention is to create a compact modular construction and, optionally, an oxygen-reduced illumination zone.
