| 20100202103 | Housing for Electrical Operating Meanas - The invention relates to a housing ( | 08-12-2010 |
| 20100103684 | LIGHT HAVING A HOUSING PART AND A COVER - A light includes a housing part and a translucent cover connected to the housing part, in a pressure-tight manner, by a screw-on ring. A flame-extinguishing gap is formed between the housing part and the cover. The flame-extinguishing gap is formed directly between a surface of the cover, and a surface of the housing part, and the screw-on ring covers the flame-extinguishing gap at the gap end pointing to the outer side of the light. | 04-29-2010 |
| 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 |
| 20090309518 | APPARATUS AND METHOD FOR MONITORING AT LEAST ONE FLUORESCENT LAMP - An apparatus for monitoring at least one fluorescent lamp, in particular in an explosion-hazard area, which fluorescent lamp has a lamp tube with electrodes arranged at its ends in the form of filaments, and has a ballast, is improved in order to avoid an excessive temperature increase while maintaining the appropriate explosion protection in that the monitoring apparatus has at least one temperature measurement device, associated with a filament, and an electronic interruption device, by means of which interruption device the power supply can be interrupted by means of the ballast on reaching a predetermined critical temperature. The invention likewise relates to a corresponding method for monitoring at least one fluorescent lamp, in particular in an explosion-hazard area. In this method, the temperature is first of all detected in the area of at least one filament of the fluorescent lamp. The determined temperature is then compared with a predetermined critical temperature, and the power supply to the filament is interrupted by a ballast if the determined temperature reaches or exceeds the predetermined critical temperature. | 12-17-2009 |
| 20090308863 | HOUSING - A housing ( | 12-17-2009 |
| 20090268440 | Portable lighting device - A portable lighting device has at least one LED light source ( | 10-29-2009 |
| 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 |
| 20080314637 | Cable Bushing Device - A cable bushing device is used to pass an electrical cable through, in particular, two adjacent housings which are explosion and/or flame-proof. The cable bushing device comprises a sleeve-like external body which can be inserted by the opposite first and second end sections into corresponding housing bores. Furthermore, the device has an insert inserted into an axial opening of the external body for retaining the electrical cables passed through the device and a fixing device for fastening the device to at least one housing. | 12-25-2008 |
| 20080311774 | Explosion-Proof Connector - An explosion-proof connector ( | 12-18-2008 |
