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 |

20130206769 | FORCING-OFF DEVICE AND CONTAINER INCLUDING SUCH A DEVICE - A forcing-off device of an, in particular, explosion-proof or flameproof container for electronic devices, the container including at least one base body having an opening surrounded by an opening edge and a cover part that can be placed onto or inserted into the opening edge. A forcing-off shoulder is formed on the base body or cover part at least in a section in circumferential direction of the container. The forcing-off shoulder is part of a shoulder running around the opening edge, and at least one forcing-off part is rotatably mounted in a lateral recess of the cover part or on the base body in an eccentric fashion between a forcing-off position and a passive position. The forcing-off part is an eccentric disc and in the forcing-off position is in abutment with the forcing-off shoulder for the gap-forming spacing of cover part and base body. | 08-15-2013 |
20140204570 | Explosion-proof LED Module - An explosion-proof LED module has at least one light-emitting diode, a heat sink connected to this and an LED cover that covers the LED at least in the emission direction. The LED cover extends into an insertion recess of the heat sink. In this insertion recess, the LED cover is surrounded by a casting compound resulting in sealing of the LED relative to an outer and possibly explosive atmosphere. As a result, an explosion-proof LED module can be provided whereby the manufacture of said explosion-proof LED module is relatively simple and possible in an economic manner in a short time from prefabricated parts. At the same time, the explosion-proof module is furthermore characterized in that sufficient cooling corresponding to the ignition protection type “intrinsic safety” and an embedding of the component according to ignition protection type “encapsulation” are given. | 07-24-2014 |
