Abstract: The invention relates to processes for preparing 2-methoxymethyl-p-phenylenediamine (I), cosmetically acceptable salts thereof, or mixtures thereof.

Abstract: Disclosed are a device, system and method for animal tracking. The tracking device comprises a tracker processing component, an energy component, a transmitting component, and a securing component. The system comprises the tracking device, a receiving device and a server. The method comprising securing the tracking device to an animal, transmitting an identification of the animal, receiving the transmission via the receiving device, modifying it and forwarding it to the server, where the modified transmission is logged and analyzed to determine animal positions.

Abstract: The present invention relates to a supply device (1) for providing at least one supply product, comprising a mounting unit (2) for mounting the supply device on a support, preferably a ceiling of a room, and an extension arm (3), wherein the extension arm (3) is arranged pivotably around a vertical pivot axis (30) relative to the mounting unit. The extension arm (3) further comprises at least one terminal (4, 4?, 4?) which is directly integrated with the extension arm (3) for a supply device.

Abstract: A method for detecting a leakage in the area of at least one cooling device of a furnace, wherein, in the event of a leakage, liquid coolant gets into a furnace chamber of the furnace from the at least one cooling device, and wherein a stream of exhaust gas is continuously removed from the furnace chamber over a period of time Z. The steps include dividing off a representative partial stream from the stream of exhaust gas during the period of time Z; condensing vaporous constituents contained in the partial stream; determining a stream of condensate obtained; comparing the stream of condensate obtained with a condensate-stream limit value; and indicating a leakage if the stream of condensate exceeds the condensate-stream limit value. Also a device for carrying out the method and a furnace with such a device are disclosed.

Abstract: A burner-lance unit (1) includes at least two gas connections (2a, 2b, 2c), a burner tube (3), and a lance tube (4) that is placed concentrically in the burner tube (3). The burner tube (3) and the lance tube (4) both have a gas inlet end and a gas outlet end (15). The lance tube (4) has a de Laval nozzle (4a) at the gas outlet end thereof. The de Laval nozzle (4a) is releasably connected to the lance tube (4). The burner tube (3) has a burner nozzle (3a) which is releasably connected to the burner tube (3).

Abstract: A temperature of a metal melt in a furnace is maintained after blowing away slag from a surface of the metal melt by the flow of oxygen and switching over from oxygen to an inert gas, such as nitrogen. A measured temperature of the metal melt is accepted as a metal melt temperature only when the inert gas flow is in a laminar state and after the measured temperature has fluctuated by a maximum of 1% over a period of at least 2 seconds.
