Abstract: Upper and lower mirror image die plates are resiliently supported and have predetermined displacement values for forming vortex generators and foldline crease channels without compressive deformation in a porous sintered metal fiber sheet material. Cutters and ridges coupled to the upper and lower die plates form the respective vortex generators and channels. The sheet of so formed material is then placed in an apparatus for bending the sheet at the foldline channels to corrugate the sheet without deformation of the sheet material between the corrugation bends. Fingers align with and engage the channels. The fingers are on plates that are ramped closer together simultaneously while the fingers on two mirror image coplanar sets of plates displace toward each other as the sheet material is folded. Pins on a pair of rotating levers engage each of the finger plates of the two sets for relatively horizontally displacing the plates and corresponding fingers as they are ramped together vertically.

Abstract: In the case of a method for operating a gas turbine group, the gas turbine group essentially consists of a compressor (1), a combustion chamber (5), a turbine (2) and a generator (3). Fuel is mixed in a premixer (18) of the combustion chamber (5), prior to the combustion, with air compressed in the compressor (1), and subsequently burned in a combustion space (19).Compressed air, fed via an air line element (15) , is mixed with fuel fed via a fuel line element (16) and delivered to a reactor (10) having a catalytic coating. The air/fuel mixture is converted in the reactor (10) into a synthesis gas comprising hydrogen, carbon monoxide, residual air and residual fuel and this synthesis gas is injected into the zones of the combustion chamber (5) where the flame is stabilized.

Abstract: In a combustion chamber of a gas-turbine group which essentially comprises a mixing section (2) for premixing an air/fuel mixture (16) and a downstream combustion space (3), a jump (5) in cross section is provided at the transition between the two said flow sections (2/3). This jump (5) in cross section induces the cross section of flow of the combustion space (3) and at the same time forms outer recirculation zones (10) in the combustion space (3). Flow passages (4) branch off in the end phase of the mixing section (2), which flow passages (4) then lead into the outer recirculation zones (10). A portion (9) of the air/fuel mixture flows out of the mixing section (2) through these flow passages (4) and into the outer recirculation zones (10), the portion being enriched here with an additional fuel (6). This fuel (6) is introduced via a circular line (19) provided with bores (18).

Abstract: In a burner of the double-cone design, bores (27) are arranged in the burner sickle (26), via which bores (27) the gaseous fuel (16), to the extent of about 3 to 8% of the total mass fuel flow, is mixed into the outer recirculation zone (28) of the burner. This leads to additional outer stabilization of the flame and to an extended operating range of the burner.

Abstract: In a method for the operation of a power station installation which essentially comprises a compressor (4), a combustion unit and a turbine (12), the combustion unit comprising a conditioning stage for at least part of the combustion air and a combustion chamber, a portion (13a) of the compressed air (13) from the compressor (4) is passed through the conditioning stage and there first of all mixed with a quantity of fuel (14a). This mixture then passes into a generator (8), in which at least hydrogen is fractionated, this hydrogen then being used in the combustion chamber. The combustion chamber comprises a start-up burner (1), a catalytic stage (2) and a downstream second combustion stage (3). Both the air/fuel mixture (16a) fractionated in the generator (8) and the further compressor air (13) enter the combustion chamber, in which interdependent combustion occurs between the combustion units acting there, relative to the running up of the installation, for the purpose of minimizing pollutant emissions.

Abstract: A system and method for processing data storage mediums (DSMs) that are not stored in an automated data storage library on medium drive devices that are part of the library. An input station used to add DSMs is enabled to serve as an input and output window for transient data storage mediums (TDSMs) so that DSMs are not dislodged from the storage bins. An operator may automatically place the library's robotic picker in a "TDSM mount mode" when an attached host processor requests one or more data volumes stored on one or more TDSMs. A library-manager controller can be automatically configured to interact with the library's robotic pickers to transfer a TDSM from the input/output station to a device, such as a tape drive within the library. The library manager controller is automatically configured to ignore the machine readable external label of a TDSM so that it is not necessary to place such a label on a TDSM.

Abstract: In a method of operating a low-pollution premixing burner (2) stabilized by means of vortex breakdown, in particular a burner of the double-cone type of construction, with gaseous fuels (4, 10), the main fuel gas (4) being fed to the burner (2) via a main gas tube (3) connected in one piece to the burner (2) and the pilot gas (10) being fed to the burner (2) near the axis of the latter via a separate feed line (9) by means of an exchangeably inserted fuel lance (8), and the pilot gas (10) being mixed inside the fuel lance (8) with air (17) fed from a plenum (16) outside the burner hood (6), the pilot-gas/air mixture (25) is fed to a catalyzer (21) arranged inside the fuel lance (8) at the tip of the burner (2) and is ignited and burnt there. The hot gas flow is then mixed with the colder main burner flow in the burner interior space (14).
