Abstract: Process for producing hollow bodies comprising fibre-reinforced ceramic materials, where cores whose shape corresponds to that of the hollow spaces are produced in a first step, a green body is produced in a second step by introducing the abovementioned cores and a press moulding compound into a mould, where the press moulding compound comprises carbon fibres and/or carbon threads and pitch and/or resins, the green body is cured in a third step by heating under pressure, the cured green body is carbonised in a fourth step by heating in the absence of oxidants to form a C/C body, and, if desired, the C/C body is infiltrated with liquid metal with retention of its shape in a fifth step, with at least partial formation of carbides occurring, where the cores comprise a material which in the fourth step melts without decomposition at a temperature above the curing temperature of the shaping by pressing of the press moulding compound; hollow bodies produced by this process and also their use as brake disks, clutch

Abstract: At least two communication systems are controlled or monitored by at least one application by transmitting data from an application to a communication system or conversely from a communication system to an application. An interposed shared service receives and processes the data in each case and subsequently forwards the data. The service sends the data to the communication systems in the same data format in each case and receives the data from the communication systems. When at least one of the communication systems uses a different data format, at least one conversion unit is connected between the communication system and the service for adapting the data formats. With this arrangement it is unnecessary to preset the application to the particular data format used by the communication system to transmit control and status information.

Abstract: Friction members are composed of a ceramic composite material. The friction members can be used for motor vehicles as a clutch disk for friction clutches, for transmitting motive power, or as a brake disk. A friction zone of the friction member is composed of ceramic, in particular of Si and SiC. A core zone of the friction member is made from fiber-reinforced C/SiC, in particular of long fiber woven fabric-reinforced and short fiber-reinforced C/SiC.

Abstract: The invention relates to a method for operating a communications system comprising at least one communications installation and at least one terminal which is connected to the communications installation. Following a user-input request for text and/or graphics information that is formatted according to a protocol for wireless transmission of text and/or graphics information (TGI), the terminal (TE1, TE2, TE3) determines address information (AI) using a selection input (SI) describing the requested text and/or graphics information (TGI) and transmits said address information to a control unit (CTL) that is allocated to the communications installation (PBX). Said control unit (CTL) establishes a connection for a packet-oriented data transmission to a server (WAP-SRV) that is described by the address information (AI) and sends a request (RQ) to transmit the text and/or graphics information (TGI) that is described by the selection input (SI) to the server (WAP-SRV).

Abstract: A brake system includes a friction coupling having organically or inorganically bound metal-containing, sintered-metal-containing and/or CFC-containing brake linings and a brake disc of fiber-reinforced C/SiC ceramic composite material. A friction layer and/or a surface of the brake disc subject to friction has a proportion of SiC greater than 65% and material compositions in a core region and a surface region of the brake disc are different. The brake system may be used in motor vehicles, rail vehicles or aircraft.

Abstract: The use of licenses is monitored in a computer or communication system which has a plurality of terminals and in which at least one license is associated with at least one user. The use of the license or licenses by each user is recorded during a defined period after the license starts to run. Based on the recording result, a message is generated and sent to the user's terminal at least if the scope of use falls short of a predeterminable value.

Abstract: A multilayer ceramic composite is described which contains at least one supporting zone having oxidation-sensitive reinforcing fibers as well as a matrix. The matrix optionally contains oxidation-sensitive components. The composite further contains at least one surface layer, as well as at least one additional protective layer disposed between the supporting zone and surface layer, and whose matrix is composed substantially of at least one component of the matrix of the supporting zone or cover layer. The protective layer further contains additives that form self-healing layers.

Abstract: A method is provided for producing a fiber-reinforced material which is composed, at least in a region of a surface layer, of a ceramic composite and has carbon-containing fibers reaction-bonded to a matrix containing the elements Si and C. In particular a method of producing fiber-reinforced silicon carbide is provided in which a structure of a matrix contains cracks and/or pores, at least at ambient temperature, because of a high thermal expansion coefficient compared with that of the fibers. Metals are selectively electrodeposited in the open pores and cracks of the matrix and, in particular, in a region of the electrically conductive reinforcing fibers. As a result, the open pores and cracks are filled and, in addition, metallic top layers are optionally formed that are firmly keyed to the ceramic composite and that may serve as an interlayer for glass top layers or ceramic top layers.

Abstract: A method and computer software program for the automated management of received messages, particularly E-mail messages, wherein a repeat presentation time, possibly a priority criterion, and a category are issued for an E-mail message after it has been opened, and the E-mail message is optionally saved in a central task folder or in accordance with the attributes in corresponding directories.

Abstract: A friction disc, in particular a brake or clutch disc, includes carbon fiber-reinforced ceramic composite material with at least one top surface formed as a friction surface. At least part of the friction surface is formed of a different material, in particular of a carbon-containing material. The different material exhibits lower wear and oxidation resistance than that of the rest of the friction surface and a supporting zone of the friction disc. A visual, audible or mechanical signal is produced under operating conditions due to comparatively greater wear. The signal provides a warning that the service life of the friction disc is being exceeded. A process for producing the friction disc is also provided.

Abstract: A telecommunication device, and associated method, for forwarding messages intended for forwarded-to subscribers, including a database which contains subscriber-related information relating to a number of forwarded-to subscribers and terminals associated with these and message formats compatible with these terminals, and a control device. On reception of a message for a forwarded-to subscriber, the control device selects via the subscriber-related information one or more terminals via which the forwarded-to subscriber can be reached, and message formats which are compatible with these terminals, converts the message with the aid of conversion modules and forwards it to the respective corresponding telecommunication network interface for transmission to the selected terminals.

Abstract: A process for manufacturing ceramic metal composite bodies, the ceramic metal composite bodies and their use. The process is based on molten infiltration and the simultaneous or delayed exchange reaction of ceramic or metal ceramic un-fired bodies or sintered bodies which may consist of nitrides or carbides as well as metals, with molten metal of additional metals, whereby new nitride, carbide and intermetallic phases are formed which have improved wear and high-temperature characteristics. These ceramic metal composite bodies can be used for tribological applications.
