The heating element comprises at least two series-connected flow heaters. The disclosure furthermore relates to a method for heating milk or milk foam, in which cold milk or cold milk foam is sucked by means of a pump out of a milk intake line connected to a milk reservoir and conveyed into an outlet line connected to the pump, and heated by means of a heating element, wherein the milk or the milk foam is conducted successively through at least two series-connected flow heaters of the heating element.

Abstract: In a cleaning device for a beverage preparation machine, in particular for a coffee machine, which includes a first chamber for receiving a cleaning agent and a liquid line system with a water line connectable to a water connection for supplying water and a discharge line connected to the first chamber and connectable to the beverage preparation machine, a first piston is insertable into the first chamber. With this cleaning device, the cleaning agent can be completely and homogeneously dissolved in the first chamber and thereby converted into a homogeneous cleaning agent solution, which can be supplied to the beverage preparation machine via the discharge line for carrying out a cleaning process.

Abstract: An apparatus for preparing a solution from an active substance and a solvent and supplying the solution to a beverage preparation machine, such as a coffee machine, includes a dissolving chamber for receiving the active substance, a supply element for supplying a quantity of the active substance to the chamber and a liquid line system coupled to the chamber and having a solvent line, which is connectable to a solvent supply for supplying the solvent. A discharge line is connected to the chamber and is connectable to the beverage preparation machine. To achieve a complete dissolution and an optimum concentration of the active substance in the solvent with a homogeneous concentration distribution over the volume of the solution, the apparatus has a piston unit which contains a first piston that can be introduced into the chamber, a second piston and a connecting line arranged between the first and second pistons.

Abstract: The invention relates to a milk frothing device 1, a beverage preparation device 100 comprising the milk foaming device 1, and a method for producing milk foam. Particularly in the coffee beverage industry, there is a need for producing a variety of different milk modifications, such as fine-pored or coarse-pored milk foam, based on different milk starting products. This often requires a variety of different equipment. The invention makes it possible to produce a wide range of different milk modifications by applying compressed air to milk on an outlet side A of a pumping device 2.

Abstract: The invention relates to an apparatus for heating and foaming a liquid, in particular a beverage, comprising a steam line (6), which can be connected to a steam generator (1); a pressurized gas line (4), which can be connected to a pressurized gas source (2); and a conveying means (3), connected to the steam line (6) and the pressurized gas line (4), for generating and transferring a steam/gas mixture into the liquid, and a controllable switching valve (5), wherein hot steam is supplied to the conveying means (3) via the steam line (6) and a pressurized gas flow under a defined constant pressure is supplied via the pressurized gas line (4) and pressure pulses (p) are generated from the pressurized gas flow by means of the switching valve (5). In order to damp the generated pressure pulses, the conveying means (3) comprises an expansion chamber (15) having a nozzle (14) arranged on the downstream end of the expansion chamber (15).

Abstract: The invention concerns a method for providing a plurality of receivers with conditional access to broadcast services using a simplified means for managing the control messages required by such conditional access schemes. The method involves providing all information which will allow a registered receiver having the necessary decryption key to access the services without having any prior rights loaded locally. A management center keeps a register of all subscribed receivers, including a list of services to which the receiver is subscribed, and encrypts the services using control words encrypted by the necessary keys. Control messages comprising the control words for decryption are provided within a special channel to which the receiver has permanent access, the special channel being a different one from channels used for broadcasting audio/video services.

Abstract: A method of operating by a second processing unit a content recorded by a first processing unit, said first and second processing units having a specific key being managed by a central server. The processing units have access to a removable storage memory intended to record a content ciphered by a content key accompanied by a file associated to the content. The content key is produced by means of a cascaded deciphering starting from the specific key of the first unit of at least two constants provided by the central server and a variable. The content is restored by the second processing unit by means of a cascaded deciphering starting from the specific key of the second unit by using the constants and the variable stored in the file accompanying the content and a transcoding key calculated by the central server.

Abstract: A method allows a broadcasted conditional access content accessible at the time of transmission to be also accessible at a later time thanks to intermediate storage on a hard disk of a user unit.

Abstract: The present invention relates in particular to a method for processing multimedia content memorised in the form of digital data in at least one multimedia unit. This method includes the following steps: reception of a program map table containing at least one indication of a proprietary type of data associated to a packet identification data (PID) as well a flag; reception of a matching table between the flag value and the real type of data; search for the flag values appearing in the program map table PMT received by the multimedia unit; search for the corresponding flag values in the matching table between the flag value and the real type of data; and modification of the program map table by replacing the indication of the proprietary type of data of the program map table with the corresponding real type of data of the matching table. The invention furthermore concerns a method for sending multimedia content in the form of digital data, as well as a multimedia unit for implementing these methods.

Abstract: The invention concerns a method for accessing services by a user unit, said services being a subset of all services broadcast by a management center and comprising at least two services, said subset of services defining a package, each service being simultaneously broadcast and containing audio/video data, the data of a service being encrypted by at least one control word, the method comprising the steps of: determining in a management center, the package a user unit is entitled to access to; determining in said management center a unique key pertaining to said user unit; forming a message containing at least one control word for each service of the package for which the user's unit is entitled, said control word being secured by the key pertaining to said user unit so that said key must be used to obtain the control word; transmitting to at least said user unit said message on at least one channel accessible whatever the selected service is.
