Patent number: 8907255Abstract: This method for deicing a direct current power supply line for railway vehicles is provided for a line extending between at least a first and a second reversible substations able to supply an electrical current circulating on the electrical power supply line, the first substation being controlled in a current supply mode, to supply an electrical current to the electrical power supply line and the second substation being controlled in a current recovery mode, to recover the electrical current from the electrical power supply line and send it back on an electrical power supply network. The method comprises establishing a voltage difference between the output terminals of the first and second substations such that a current circulates on the electrical power supply line between the two substations and that the heat produced by the circulation of the current causes the deicing of the power supply line between the two substations.Type: GrantFiled: April 19, 2011Date of Patent: December 9, 2014Assignee: Alstom Transport SAInventor: Nicolas Bellegarde

Patent number: 8890039Abstract: A method for heating a fluid line system with at least two electric heating elements (R1, R2, R3), which are operated electrically in parallel and each heating element (R1/R2/R3) is separately supplied with a controlled operating current (I1/I2/I3) for adjusting its heating power. Furthermore, the invention relates to a heating system for such a fluid line system (1), in particular for the application of the method according to the present invention. The heating system has heating elements (R1-R3) which are electrically connected in parallel and are each connected to a separate control element (T1, T2, T3). Each heating element (R1/R2/R3) can be controlled via its associated control element (T1, T2, T3) for the individual adjustment of its heating power.Type: GrantFiled: November 25, 2009Date of Patent: November 18, 2014Assignee: VOSS Automotive GmbHInventors: Tobias Etscheid, Olav Borgmeier, Thomas Schüler

Patent number: 8803038Abstract: An apparatus for image formation comprises a fixing unit, first to fourth switching units, a DC power supply unit, an accumulating unit, a charging unit, and a switching control unit. The first switching unit switches the state of connection between the fixing unit and a commercial power source. The DC power supply unit supplies another electric load of the apparatus than the fixing unit with DC power. The second switching unit switches the state of connection between the DC power supply unit and the commercial power source. The third switching unit switches the state of connection between the charging unit and the commercial power source. The fourth switching unit switches the state of connection between the accumulating unit and the electric load.
