20100288929 | Device and method for detecting flames - A device for detecting flames in which at least two identical detectors are disposed next to one another. Each detector has an identical signal processing circuit having an amplifier and an A/D converter, and a symmetrical and similar layout, i.e., conductor track placement. Each of the detectors covers a different wavelength range, by way of a preceding filter, and the signal detection takes place at the same time and synchronously, so that a precise analysis of the received radiation occurs using simple algorithms, independent of disruptive influence variables. By using the same detectors and the same signal processing systems, as well as the symmetrical and similar configuration of the conductor track placement, as well as the synchronous control of the signal recording, interference variables occur uniformly on all optical reception channels. This uniform interference can be compensated without complicated algorithms. | 11-18-2010 |

20080265540 | Guiding Element for a Track Element in a Wheel Suspension of a Vehicle - A guide element for a guideway element in a wheel suspension of a vehicle has one of the elements arranged such that it is connected essentially rigidly to the body and the other element arranged such that it is connected essentially rigidly to the wheel and a plain bearing, which makes possible a displacing motion of the guide element on the guideway element, is formed between these elements. The guide element is guided in a rotatingly movable and/or pivotingly movable manner on the guideway element via a joint arrangement, within which the plain bearing ring is arranged, which is guided with its circular passage opening, adapted to the cross section of the guideway element, on the guideway element. This joint arrangement may be designed as a rubber bushing or as a ball and socket joint. A plurality of sliding rings may be arranged in a so-called ball layer hollow body one on top of another and at least with a section facing the guideway element essentially at right angles to the longitudinal axis of the guideway element in a slightly displaceable manner. A guideway extending in a curved shape can thus be embodied. The sliding ring may have an elastomer ring, to which a metal bushing is vulcanized on the outside and to which a plastic sliding ring, which is in contact by its inside with the guideway element, is vulcanized on the inside. | 10-30-2008 |

20090115116 | LIMIT STOP FOR A DOOR OR LID OF A MOTOR VEHICLE - A limit stop with an elastomer resilient element, which is to be secured on a door or lid and/or on an opposing stationary vehicle section for damping forces generated when the door or lid strikes stationary chassis parts of a motor vehicle. The limit stop includes an additional damping section disposed adjacent to and cooperating with the elastic resilient element in a spring deflection direction of the resilient element. The damping section comprises at least two chambers filled with a fluid and a nozzle plate arranged between the chambers with at least one channel extending through the nozzle plate and connecting the chambers. The fluid is displaced from one of the chambers into the other chamber during a spring deflection of the elastomer resilient element, thereby producing a pressure force which is caused by the buildup in pressure when the volume of one of the chambers decreases and augments the return force of the resilient element. | 05-07-2009 |
