  • Publication number: 20140070495
    Abstract: A seal assembly for sealing at least one negative or positive pressure zone which adjoins a surface which is perforated and moves in a movement direction in a machine for making paper, tissue or cardboard, has at least one sealing element which lies opposite the moving surface and is arranged in a receptacle which can be moved to change the format of the negative or positive pressure zone. In order to simplify the adjustability of the receptacle in order to position the sealing element, there is a signal transmitter which is connected directly or indirectly to the sealing element and the signal of which can be received on that side of the moving surface which faces away from the sealing element.

  • Publication number: 20140058947
    Abstract: A rule set for an AVC system permits AVC operations to be performed at various levels of hierarchy within a governing budget data structure. A rule set contains a plurality of rules, each having an address field which relates an arbitrarily assigned control object to budget nodes in a budget data structure. Control objects typically are assigned to various units and aggregation levels within an organization and also across other dimensions. Rule arrays with several independent rule sets can be activated in parallel for checking an individual input data record against multiple budgetary requirements defined for the organization. This structure provides a comprehensive AVC control feature even for very large budget data structures and complex budgetary control environments.

  • Patent number: 8472895
    Abstract: A method for controlling power amplifiers for digital transmission includes converting a digital modulation signal according to envelope elimination and restoration into an amplitude signal and into a phase-modulated carrier signal. The amplitude signal and the phase-modulated carrier signal are combined in a final stage so as to provide a transmit signal. The amplitude signal is automatically monitored by a module that employs a distribution-density function of the amplitude signal in order to determine a direct component error of the amplitude signal. The distribution-density function of the amplitude signal corresponds to a Rayleigh function if the energy of the complex modulation signal is distributed approximately uniformly within a bandwidth being used. If the spectral power density has an approximately rectangular form, the Rayleigh function is used to determine the direct component error. The direct component error is determined from the amplitude signal.

  • Patent number: 8433480
    Abstract: A device and a method for triggering personal protection devices, characterized in that a roll rate sensor generates a roll rate while an acceleration sensor detects the transverse acceleration and the vertical acceleration. An integrator is provided to integrate the roll rate to yield an angle. The integrator starts integrating the roll rate when the roll rate exceeds a first threshold value and it stops the integration when the roll rate falls below a second threshold value. In addition, a threshold value controller is provided, adjusting the first and/or second threshold value according to the transverse and/or vertical acceleration. A processor triggers personal protection devices according to the angle and other criteria.

  • Publication number: 20110156621
    Abstract: A rail vehicle has a permanent-magnet synchronous motor as its traction motor. A switching apparatus is arranged between a converter and the traction motor, connects the traction motor to the converter in the driving mode and connects the traction motor to at least one braking resistance during generator operation of the traction motor. The switching apparatus can be operated pneumatically and is for this purpose connected to a main air control line of a compressed-air braking system. In the driving mode, when the pressure in the main air control line is greater than a threshold value, the traction motor is connected to the converter. For braking, when the pressure in the main air control line is less than the threshold value, the traction motor is connected to the at least one braking resistance.

  • Publication number: 20110161214
    Abstract: A budgetary control system limits revenue generating transactions that may be entered in an enterprise management system. When a new revenue posting is proposed to the system, various AVC rules are evaluated. The evaluation compares the revenue posting against predetermined budgetary limits. The AVC rules may address various nodes within a revenue postings data structure and within a revenue budget data structure and they may define a test relationship that must be maintained between them. If proposed revenue posting would violate the test relationship of an AVC rule, then the revenue posting may be rejected from the system depending upon the contents of a response field in the AVC rule. Some AVC rules mandate that a violation cause the proposed transaction to be blocked while others may generate a warning notification within the system but admit the new transaction despite the violation.
