Abstract: A method for operating an on-board water supply and distribution system of an aircraft for supplying water includes a central water tank, first consumer assemblies with buffer tanks each including a heater to heat up water in the buffer tank to a disinfection temperature, pump having upstream and downstream sides to operate in supply and reverse modes, and high-pressure conduit system. The central water tank connects to the pump's upstream side. The conduit system connects the downstream side with a first consumer assembly. The method includes operating the pump in supply mode where water from the central tank goes to a first consumer assembly to fill a buffer tank, operating a buffer tank heater so water heats to a predetermined disinfection temperature, and operating the pump in reverse mode so heated water passes through a part of the conduit system and the upstream side of the pump.

Abstract: A composite material, a method for the production thereof, and a fire protection element containing the composite material can be utilized for the protection of passage openings in components in the event of fire, such as building parts, through which conduits are guided. The composite material can be also used as a fire protection element for sealing passage openings and/or for joints in components.

Abstract: Predicting a refill requirement for wash substances for performing a vehicle wash using a wash system for the car wash for performing the vehicle washing, wherein the control module is for providing a refill data set for predicting a refill requirement for washing substances. The control module comprises at least one measuring device for detecting current fill level data for each of the washing substances and a data link between the at least one measuring device and the control module for transmitting the detected fill level data to the control module. The control module is designed to perform a prediction function for calculating a refill data set, in which a prediction of the refill requirement is encoded, based on planning data, which represent planned vehicle washes at the washing system taking into account washing-substance-specific consumption data.

Abstract: A combination air eliminator and flow balancer for a fluid circulation system includes a tank having a supply inlet, a supply outlet, a return inlet and a return outlet. The tank defines an interior having a vertical cylindrical configuration. The supply inlet is located above the supply outlet, the return inlet and the return outlet. The supply inlet introduces fluid into an upper portion of the interior of the tank in a tangential direction to induce rotational downward flow between the supply inlet and the supply outlet, which separates air contained within the fluid. The air migrates upwardly within the tank interior and is vented.

Abstract: A motor vehicle having a unit, particularly a drive assembly, which is operated by a fuel that is cryogenically stored in a vehicle tank, is provided, in which fuel is heated by a heat exchange with a warmer medium. The fuel taken from the vehicle tank comes in contact with the cold side of a thermoelectric generator, particularly in the form of a Seebeck element, in order to generate electric current for the electric power supply of the vehicle. The warm side of the thermoelectric generator is preferably acted upon by the warmer medium also used for the heat exchange with the cold fuel, in which case the thermoelectric generator may be integrated in a heat exchanger for the heat exchange between the fuel taken and the warmer medium.

Abstract: A method and system is provided for authenticating electronic forms prior to download. A Form Administrator may enable authentication requirement for an End User and also select an authentication scheme. The End User will not be allowed access to an electronic form unless authenticated. The invention also includes a method and system for delivering and presenting electronic forms to an End User through a purely browser based application, without requiring the installation of additional software or browser plug-ins.

Abstract: An operator control device for controlling systems in a motor vehicle by inputs by a user includes a touch-sensitive operator control panel on which it is possible to represent two surface shapes which may be changed into one another alternately, with the first surface shape being structured so as to be capable of being sensed in a tactile fashion so that it may be used to select zones on the operator control panel in order to select menu items. The individual selectable zones may be configured differently in shape, extent and their position on the operator control panel, and the second surface shape is smoothed in comparison with the first shape so that hand-written and graphic inputs are possible with it.
