Further, a pretensioning device is provided, which is supported on the wheel disk as well as on the blade root and which exerts a pretensioning force on the blade root in the radial direction. The pretensioning device is designed such that the pretensioning force can be adjusted when assembling the turbomachine rotor.

Abstract: An apparatus for the production of ionized oxygen and ozone from pure oxygen. An adjustable high voltage power supply is connected to an ozone generator having at least one ozone generator therein. The HV power supply has a relatively low voltage setting for producing negative ionized oxygen and a relatively high voltage setting for producing ozone. A negative ionizer may be included to increase the concentration of negative ionized oxygen. Outputted gasses are directed to a hermetically sealed envelope positioned around and in spaced relation from the surface of a patient's injury. If the wound is infected, ozone is selectively used to treat the infection for a first predetermined period of time sufficient to neutralize the infection. After the wound is treated with ozone, negative ionized oxygen is selectively used to treat the wound for a second predetermined period of time sufficient to enhance the healing of the wound.

Abstract: A swirl spraying nozzle for spraying liquid fuel is provided. The swirl spraying nozzle includes a nozzle body including a hollow cylinder with a base terminating the hollow cylinder on one side and with a head terminating the hollow cylinder on the other side such that a swirl chamber is formed in the nozzle body.

Abstract: An apparatus for providing a sequence of video frames includes a video frame generator adapted to provide the video frames on the basis of the scene model. The video frame generator is adapted to identify within the scene model a scene model object having a predetermined object name or a predetermined object property, and to generate the sequence of video frames such that user-provided content is displayed on a surface of the identified scene model object or as a replacement for the identified scene model object. An apparatus for creating a menu structure of a video medium includes an apparatus for providing a sequence of video frames. The apparatus is adapted to generate the sequence of video frames being part of the menu structure on the basis of a scene model, on the basis of additional information, and on the basis of a menu structure-related characteristic.

Abstract: A system, computer program product and method of correlating safety solutions implemented in a facility with the facility's business climate are provided. The system, computer program product and method are used for designing safety solutions for a facility. While doing so, a user such as a security consultant, may derive a plurality of variables from the safety solutions. The variables are used to calculate a business climate index and a safety level from which a value for a safety/climate coefficient may be calculated. The value of the coefficient indicates whether the threat level is greater than the security level, or whether the security solutions are adequate or too intrusive.

Abstract: The invention relates to a method and a circuit arrangement for the ageing compensation of an organic light-emitting diode (OLED) which is fed from a supply voltage and is switched by means of a driver transistor operated in saturation operation, by means of a driving of the light-emitting diode.

Abstract: A turbine blade is provided. The turbine blade includes a support structure and a shell which surrounds the support structure and which is connected to and at a distance from the support structure by at least one spacing element. For example the spacing element can be a solder globule in order to form a space through which a cooling medium can flow between the support structure and the shell. A method for the production of a turbine blade having a support structure and a shell which surrounds the support structure and which is connected to and at a distance from the support structure is also provided. The shell is soldered to the support structure in at least at one place of the support structure in order to connect the shell to and at a distance from the support structure.

Abstract: The invention relates to a closing assembly for closing the gap remaining between the first and last blade of a blade ring that is inserted into a peripheral groove of turbomachinery. Said assembly comprises at least two parts each of which can be hooked onto projections that form an undercut in said peripheral groove and comprises a securing element, which secures the parts from becoming detached from the peripheral groove. To provide a closing assembly for closing the remaining gap, which can be simply and cost-effectively detached and which reliably withstands high mechanical stress, the securing element is mounted to rotate about its longitudinal axis between the two parts and has a key head and a web.
