| 20090261733 | MONITORING DEVICE - A monitoring device for monitoring at least one fluorescent lamp, particularly in areas at risk of explosion, which fluorescent lamp has a lamp tube with electrodes arranged on the ends thereof in the form of coils, and lamp sockets assigned to said electrodes, is improved for preventing large temperature increases in a corresponding fluorescent lamp, particularly in areas at risk of explosion, by complying with the appropriate explosion safety measure, in that the monitoring device has at least one temperature measuring device assigned to a coil, and one electro-mechanical interruption device with which the energy supply to the fluorescent lamp can be interrupted upon reaching a preset critical temperature value. | 10-22-2009 |

| 20090323255 | PLUG-IN HOUSING MODULE - A plug-in housing module for forming an especially explosion-proof switchgear/distribution panel with a number of plug-in points contacts electrical connection devices when occupying its plugged-in position, and is detachably fixed to carrier rails or the like of a frame of the switchgear/distribution panel in the plugged-in position. The aim of the invention is to improve such a plug-in housing module in such a way that, without switching the entire panel off circuit, a plug-in housing module can be easily inserted into a corresponding plug-in point or removed therefrom even by an untrained person. To this end, the plug-in housing module comprises at least one switching device which is accessible from the outside for switching between a locking position and a release position and which, in the release position, can be moved out of the plugged-in position into a separation position, wherein in the separation position the contact with the electrical connection device is interrupted, while maintaining a flameproof mechanical connection, and the separation position is determined in relation to the plug-in point by means of an especially mechanical locking device. Once the locking device has been released, the plug-in housing module can be fully removed from its plug-in point. | 12-31-2009 |
| 20100032204 | THREADED CABLE GLAND - The invention relates to a threaded cable gland comprising a threaded sleeve, a stop ring arranged externally on the threaded sleeve, a retaining nut which is screwed onto the threaded sleeve and a sealing element arranged within the threaded sleeve. In order to improve the threaded cable gland such that modifications of the gap widths and thus the flame protection are avoided by means of a simple construction, a dwell pressure element is disposed between the retaining nut and the sealing element within the threaded sleeve for acting upon the sealing element. | 02-11-2010 |
