Abstract: The invention relates to a method for operating a fuel-operated auxiliary heater (10) in a motor vehicle, wherein by means of at least one fuel type sensor (18a-f), the type and/or composition of a fuel (26) which is provided for combustion in the auxiliary heater (10) or which burns or is burned in the auxiliary heater (10) is determined, and a control unit (12) for controlling the auxiliary heater (10) sets present operating parameters as a function of the determined fuel type and/or composition. In order to avoid damage during relatively long downtimes, it is proposed that the downtime of the auxiliary heater (10) following a previous operation of the auxiliary heater (10) is measured and compared with a threshold value which is determined as a function of the fuel type and/or composition determined during the previous operation of the auxiliary heater (10), and that, if the threshold value is exceeded, the control unit (12) generates and outputs a signal in order to initiate renewed operation of the auxiliary heater (10).

Abstract: Mobile distribution equipment for supplying food catering stands, toilet facilities with current as well as with water at folk festivals and other large congregations of people, such as rock concerts must meet high safety standards despite flexibility in use, with the housing (2) provided with carrier struts (3) between which the supply modules are releasable arranged on different sides, and between the incoming and output terminals the distribution lines are enclosed by the recesses or troughs encapsulating the supply modules.

Abstract: The invention relates to a method of manufacturing a heat exchanger ( 10 ) for an air heating apparatus ( 12 ) for integration into a housing which guides air. The heat exchanger has a heat exchanger body ( 14 ) with a longitudinal axis. According to the invention, the heat exchanger body ( 14 ) is at least partially fabricated in a pressure-casting process employing two molded masses ("cores"), with the molded masses being withdrawn from the mold in opposite directions ( 40, 42 ) extending along the longitudinal axis.
