| 20090254506 | DYNAMIC SERVICE SELECTIONS USING ENHANCED ONTOLOGIES - Embodiments may include a system for generating an enhancement of an ontology. The system may have a memory unit and a processing unit. The memory unit may be configured to provide the ontology and to store the ontology with the enhancement. The processing unit may be configured to identify a service specification, such as a service product or a contract, that may be represented by a class of the ontology. The service specification may describe a capability of a service. The processing unit may be further configured to compute a set of instances that are specified by the service specification and by a requirement specification and to enhance the ontology with a generated class representing the set of instances in case that the set of instances has one or more instances. | 10-08-2009 |

| 20100186474 | METHOD OF MAKING THROUGH-PASSAGES IN SHEET METAL PARTS - In a method of making through-passages in a perforated U-shaped sheet metal part, an inner core is positioned between confronting legs of the sheet metal part in an area of holes, and a support bar is inserted through one hole into the sheet metal part for support of a backside of the inner core. A shaping punch is inserted through another opposite hole into the inner core, thereby forming an inwardly directed collar. After retracting the support bar and the shaping punch and transferring the sheet metal part to replace the first inner core with a second inner core, a centering bar is inserted through the collared hole into the sheet metal part to center the sheet metal part in relation to the centering bar and to support a backside of the other inner core. A further shaping punch is then inserted into the second inner core through the first hole, thereby forming an inwardly directed collar so that the two collars are aligned and form through-passages. | 07-29-2010 |

| 20100066281 | TRACTION DRIVE OF A RAIL VEHICLE FOR DRIVING AND GENERATIVE BRAKING - The invention relates to a traction drive for the driving and generative braking of a rail vehicle or a combination of rail vehicles, a permanent-field synchronous motor and a traction current converter being respectively associated with at least two axles of the rail vehicle or combination of rail vehicles. The traction current converter includes at least one pulse current converter on the engine side, and the clamps of the permanent-field synchronous motor are connected to a change-over switch such that the permanent-field synchronous motor can be connected to a load circuit containing at least one load element, in order to drive the pulse current converter or for generative braking. According to the invention, the load circuits connected to the permanent-field synchronous motors for generative braking are designed such that the brake characteristic lines of the permanent-field synchronous motors differ in terms of characteristic features such as the position of the maximum of the brake torque according to the rotational speed. | 03-18-2010 |
| 20100066282 | TRACTION DRIVE OF A RAIL VEHICLE FOR DRIVING AND GENERATIVE BRAKING WITH LOAD CORRECTION - The invention relates to a traction drive for the driving and generative braking of a rail vehicle or a combination of rail vehicles, at least one permanent-field synchronous motor and a traction current converter being associated with at least one axle of the rail vehicle or combination of rail vehicles. The traction current converter includes at least one pulse current converter on the engine side, and the clamps of the permanent-field synchronous motor are connected to a change-over switch such that the permanent-field synchronous motor can be connected to a load circuit forming a load, to drive the pulse current converter or for generative braking. According to the invention, the load circuit connected to the permanent-field synchronous motor for generative braking is designed and/or controlled in such a way that the characteristic values of the load circuit can be modified according to the loading of the rail vehicle or combination of rail vehicles. | 03-18-2010 |
| 20100078527 | DEVICE AND METHOD FOR ERROR MONITORING FOR UNDERCARRIAGE COMPONENTS OF RAIL VEHICLES - The invention relates to a device for monitoring errors in undercarriage components of rail vehicles, having at least one acceleration sensor which works with an evaluation unit. At least one acceleration sensor is arranged on the undercarriage of the rail vehicle in such a manner that its direction of detection has at least one component parallel to the vertical axis (z-direction) of the rail vehicle. The invention proposes that the acceleration sensor is constructed in such a manner that it delivers a measuring signal which contains the signal portion corresponding to a ground acceleration, or represents a signal corresponding to a ground acceleration, and that the evaluation unit has a routine for testing functions of the acceleration sensor, the routine controlling an error signal if the measuring signal delivered by the acceleration sensor contains no signal portion corresponding to a ground acceleration. The routine also suppresses the error signal if this is not the case. | 04-01-2010 |
| 20100116041 | DEVICE FOR ERROR MONITORING OF CHASSIS COMPONENTS OF RAIL VEHICLES - The invention relates to a device for the error monitoring of chassis components of rail vehicles, including at least one vibration sensor. According to one embodiment of the invention, at least one vibration sensor is arranged on a bogie frame or on a wheel set bearing of an axis of a bogie of the rail vehicle such that the detection direction thereof has a component in the moving direction (x-direction) or a component perpendicular to the moving direction (y-direction) and at the same time a component parallel to the vertical axis (z-direction) of the rail vehicle. | 05-13-2010 |

A guide tube arranged in a pressure tube. A piston is guided in the guide tube. A piston rod is fastened to the piston, and extends through a second work chamber guided outward by a sealing and guiding device at a first end of the pressure tube and is arranged with its other end at the base part of the vertical tube. A flow connection between the first work chamber and the second work chamber can be shut off by a valve which can be actuated by an actuating device. The pressure tube is arranged to be movable along the center longitudinal axis relative to the telescope tube. | 06-16-2011 |
