Patent DE-58900778-D1 (DE)
Inventor: BLOTENBERG WILFRIED DR ING
IPC: F04D27/02

Abstract: In the case of known control methods for turbocompressors, in order to prevent surging before the working point of the compressor reaches the surge limit, it is ensured by controlled opening of at least one venting or reversal valve on reaching a venting line parallel to the surge limit that the flow through the compressor does not fall below a minimum through-flow which varies as a function of the delivery pressure. The disadvantage to these known methods is that surging cannot always be reliably prevented, particularly in the case of rapid shifts in the working point in the direction of the surge limit. The new method is intended to avoid this disadvantage. 
<??>The new method proposes that in addition the rate at which the working point shifts in the direction of the surge limit be determined in the performance characteristics and that if a rate-related rapid opening line running at various distances from the surge limit is exceeded, rapid opening of the venting or reversal valve be superimposed on the normal venting control. This means that opening of the venting valve occurs at the latest possible moment but always in sufficient time. The compressor can thereby still be operated safely at levels closer to its limit which results in more economic partial load operation and greater surge safety. 
<??>The new method is suitable for controlling turbocompressors for widely varying applications, for example in blast furnace blast generators, in petrochemical processes or the manufacture of fertilizers.

Abstract: A method and a device for decorating objects (32) having a conical outer surface (34) with a pattern from an embossing film (10) are described, wherein the embossing film (10) is unwound from a supply roll (100), deflected around a deflection roller (46) and subsequently fed to an embossing station (36), in which a pattern from the embossing film (10) is embossed onto the outer surface (34) of the object (32). With the aid of an adjusting device, the deflection roller (46) and the supply roll (100) execute a linear movement parallel to the longitudinal axis of the supply roll (46) and, at the same time, a swivel movement about a swivel axle (50) which is perpendicular to its longitudinal axis. In this case, the deflection roller (46) is displaced continuously in a linear manner about a route which corresponds to the deviation between the straight-line course of the embossing film (10) and the curve of the layout of the conical outer surface (34) of the object (32) to be decorated. At the same time, the deflection roller (46) is continuously swivelled through an angle (b) so that the straight-line course of the embossing film (10) is adapted in relation to the respective opening angle (b) to the curved layout of the conical outer surface (34) of the object to be decorated.

Date Jun. 9, 1994A radio telephone system is disclosed to satisfy in the short term basic telecommunication needs of areas which are insufficiently or not yet covered. The system has a number of duplex radio channels (transmission channels) substantially smaller than the number of radio telephone subscribers. These transmission channels are connected to the ports of a telecommunications exchange system which is part of the stationary radio station and which ensures both incoming and outgoing traffic with the public telecommunications network and internal exchanges within the system. Signalling, exchange, management, servicing, and special functions of radio operation between the stationary radio station and the subscriber connection device are ensured by a radio switching device which uses one, or if required, several transmission channels used as organization channels and not connected to the ports of the telecommunications exchange system. In the organization channel, a constant time-multiplexed communication is maintained with the subscriber connection device according to a random access process based on a special organization channel protocol. An essential characteristic of the invention is that the subscriber connection devices have an a/b interface for the connection of telecommunication terminals. The system and in particular the organization channel protocol are designed in such a way that no differences from a wired telecommunications connection are perceptible to the user, although the system is radio operated.
