  • Publication number: 20090242697
    Abstract: According to the invention, inflatable buoyancy bodies are kept in storage housings on the outside of a vehicle. During normal use, buoyancy bodies are folded up and stored under covers. Only when the vehicle is on water do the covers open and buoyancy bodies fill with air. An on-board compressed air system supplies air for filling buoyancy bodies so that air, which is not required by a braking installation or the like of the vehicle, is used to fill the buoyancy bodies. The additional use of outside air enables more air to be supplied to the buoyancy bodies at a low pressure than the sole use of the on-board compressed air system. In order to empty the buoyancy bodies, a vacuum is generated in connection lines. When stop cocks are open, air is sucked out of the buoyancy bodies, which then fold up and the covers are closed and locked.

  • Publication number: 20080205654
    Abstract: The present invention relates to a method and a security system for the secure and unequivocal encoding of a security module, in particular a chip card. To this end, a security module (10) is personalized during the manufacturing process in a secure environment in that the manufacturer stores a unique identifier (IDSM1) in a memory (14) of the security module (10). The secure encoding to ensure the uniqueness of the security module (10) is achieved in that the item of information to be kept secret and intended for the security module (10) is encrypted not only by a communication key, but by the unique identifier (IDSM1) of the security module (10). This ensures that the item of information to be kept secret is able to be decrypted only by the security module (10) with which the unique identifier (IDSM1) is associated, and used for safety-relevant applications.

  • Publication number: 20070297796
    Abstract: Two data signals are subjected to a binary differential phase modulation and transmitted as POLMUX multiplex signals. The types of modulation are selected in such a way that they are orthogonal in relation to each other and do not influence each other during the demodulation of the signals. There is thus no need to regulate the polarization on the receiving side.

  • Patent number: 7270793
    Abstract: A process for producing a phosphate of the lanthanoids is described. The process is based on a two-jet precipitation, starting from separate reservoirs of a rare earth salt solution and a phosphate solution which are introduced simultaneously by separate feedlines into an aqueous acidified initial charge with stirring at a pH of 0?pH?1. After the solutions are added, the pH is raised to a pH of >2 to complete the phosphate precipitation.

  • Patent number: 7179319
    Abstract: The invention proposes a fine grained sintered cemented carbide containing chromium and based on WC and a binder based on Co or CoNiFe, and having at least one additional phase comprising at least one carbide or mixed carbide of tantalum. For improving the high-temperature properties while simultaneously maintaining a good trade-off between hardness and bending strength, it is proposed that the sintered cemented carbide contains approximately 0.3 to 4% Ta, as related to the total mass of the sintered cemented carbide, that the WC has a grain size of between 0.1 and 1.3 ?m, that the binder phase contains the metals W, Cr and Ta, dissolved in solid solution, and that the at least one additional phase comprises a TaC phase visible by optical microscopy. The invention further relates to a powder-metallurgical process for manufacturing the sintered cemented carbide and to the use of the sintered cemented carbide for manufacturing cutting tools having improved high-temperature properties.

  • Patent number: 7174228
    Abstract: A display for on-site visualization of conditions of an automated process is disclosed. It comprises a display controller which at least temporarily provides a state indication signal representing a constellation of states of at least two process data signals. At least one of the two process data signals is derived from a signal generated externally to the field device. The field device has a display element which responds to a change in the state indication signal with a significant change in its appearance, thus signaling the constellation of the states of the two process data signals in a visually perceptible manner. Therefore, the field device is particularly suited for on-site monitoring of entire plants or sections thereof by operating personnel.
