| 20090139983 | Electric Heating Apparatus, Especially for Motor Vehicles - The invention describes a heating apparatus comprising at least one heater ( | 06-04-2009 |
| 20100045421 | Electric Circuit With Thermal-Mechanical Fuse - A electric circuit includes a connection to a current source, an electric load, and a thermal-mechanical fuse which, in the case of failure at an excessive heat emission, interrupts the current supply to the load, which is effectuated by a feeder in which is arranged a spring having two ends, at least one end is soldered to a solder point provided in the feed line. The one solder point is under a mechanical pretension caused by the restoring force of a spring, that separates the solder joint between the spring and the solder point in the feed line, when the solder melts at the solder point. | 02-25-2010 |
| 20110051388 | PRINTED CIRCUIT BOARD WITH A FUSE AND METHOD FOR THE MANUFACTURE OF A FUSE - Some invention embodiments relate to a method for forming a fuse which electrically connects two metal surfaces ( | 03-03-2011 |
| 20110069943 | Apparatus for Heating Fluids - The invention relates to an apparatus for heating fluids, comprising a housing in which a duct runs, through which the fluid to be heated can flow and which leads from a housing opening for fluid to enter to a housing opening for fluid to exit. According to the invention, the duct extends in several convolutions along a housing wall carrying at least one heater housing, in which at least one electric heating element is arranged. | 03-24-2011 |
