Abstract: A method includes receiving electric field data regarding an electric field that is detected in an underwater environment by a plurality of electrodes mounted on a first structure, and receiving sensor data from at least one sensor mounted on the first structure. The sensor data relates to a sensed location of a second structure. The method includes determining location data including information regarding a location of the second structure relative to the first structure in the underwater environment based on the sensor data, and determining one or more characteristics of the second structure based on the electric field data and the location data.

Abstract: The present invention provides a process for preparing 1,2-pentanediol by reacting furfuryl alcohol with hydrogen in the presence of a catalyst system. The catalyst system contains platinum oxide or contains ruthenium supported on aluminum oxide or activated carbon. The invention also relates to the respective catalysts and processes for producing the catalyst system.

Abstract: The invention relates to a cooling box (1) for electric or electronic components, consisting of a material. Said cooling box (1) is non-electrically conductive or practically non-electrically conductive, is configured in one piece or multiple pieces and has a cavity (4) that is enclosed by the material, said cavity (4) being closed or provided with at least one opening (2). To improve thermal dissipation, at least one surface region of the cooling box (1) is defined by functions of electrical and/or thermal conductivity.

Abstract: The invention relates to a lamp, e.g. a UHP-Lamp, comprising a burner (10) with an ionizable filling and an amount of mercury contained therein, having a housing (30, 60; 20, 30) with at least one port (40), whereby the inner opening surface (50) area of the port/s is adapted to reduce the amount of mercury which is able to expose to the outside after an explosion of the burner (10).

Abstract: The invention relates to an illumination unit that comprises at least a reflector (3) and a UHP lamp (2), which UHP lamp has at least one burner (20) having a discharge chamber (21), wherein, when the lamp is operating, at least part of the IR light emitted from the burner material of the UHP lamp (2) makes its way back to at least a part of the burner (20) by reflection from the reflector (3) and/or from another component of the illumination unit (1).

Abstract: An electric lamp provided with a bulb (1) of quartz glass and a metal electrode rod (3;21,22). The electrode rod (3;21,22) is at least partly embedded in the quartz glass material of the bulb. At least a major part of the surface of the electrode rod (3;21,22) that is in contact with the quartz glass material is provided with grooves (6) having a substantially longitudinal direction.

Abstract: A microcapillary reactor contains at least one first static mixer comprising at least one first capillary supply line for a first fluid and at least one second capillary supply line for a second fluid which is not substantially homogeneously miscible with the first fluid. The first and second capillary supply lines flow into a region which is the point of departure for at least one transport line. The first and second capillary supply lines are dimensioned such that the first and second fluids can be respectively transported in laminary flow conditions and can be displaced in the form of alternatingly successive discrete liquid phase sections (plugs). The microcapillary reactor further comprises at least one second static mixer, comprising at least one third supply line, particularly a capillary supply line, for a gaseous third fluid which flows in the first capillary transport line downstream from the first mixer.

Abstract: The invention refers to a method for removing traces of hydrocarbons, particularly propane, from gas flows. The conversion of hydrocarbons into carbon oxides is achieved by loading suitable carrier materials, such as e.g. TiO2 or Al2O3, with ruthenium as active component, possibly doping them with one or more further element(s), and subsequently calcining and/or reducing them at an increased temperature. By means of these catalysts, and at 20 to 150° C. and while adding molecular oxygen, hydrocarbons, particularly propane, in concentrations ranging from 0.1 to 2,000 ppm are oxidized.
