Abstract: The invention relates to a rotor for a non-positive-displacement machine, particularly a rotor for a compressor of a gas turbine, on which at least one shaft collar with an outer periphery and with two radially extending faces are placed. The rotor also comprises a multitude of retaining grooves for moving blades, said retaining grooves being provided on the outer periphery and extending transversal to the peripheral direction and each retaining groove has a groove bottom. In order to provide a rotor for a non-positive-displacement machine that makes it possible to reduce flow losses while having a simple geometrical design of the attachment of moving blades, the invention provides that an annual groove, which extends in an axial direction and which is coaxial to the rotation axis of the rotor, is provided at least on one face of the shaft collar.

Abstract: A method according to the invention or a corresponding device (1) provides for dividing exhaust gas (9) exiting the gas turbine into a first (11) and a second partial stream (13), for mixing the first partial stream (11) with combustion air (15), and for channeling the resulting mixture (17) to the combustion chamber (5) and the second partial stream (13) to a carbon dioxide precipitation plant (21). In an advantageous embodiment the exhaust gas (9) exiting the gas turbine (3) is previously used to generate process steam (31) for a steam turbine (33) (gas and steam power station) then cooled before the exhaust gas (9) is divided into said partial streams (11,13). Water (29) precipitating during cooling is removed.

Abstract: This invention discloses a conductor roll that is surrounded by a crown that extends along a substantial portion of the length of the conductor roll. The crown is designed to compensate for the deflection of the conductor roll when the conductor roll is placed under a load.

Abstract: The shaft bearing supports the rotor of a turbo-machine which extends along a rotor axis. The shaft bearing has a bearing element with a bearing surface. The bearing surface supports an associated rotor surface and the bearing element can be axially displaced. The invention further relates to a turbo-machine and to a method for operating said turbo-machine.

Abstract: A device and a method for burning fuel in air. The device includes an annular passage for directing the air in a meridional flow with regard to an axis. A swirl cascade is provided for imposing a swirl on the flow, and a mixer for intermixing the fuel with the flow for forming an essentially homogeneous mixture. Also present is an air flow delayer for delaying a portion of the flow that lies radially on the outside with regard to the axis relative to other portions of the flow. The device is configured in particular as a premix burner, for example for use in a gas-turbine plant.

Abstract: A fuel nozzle configuration for a fluid-fuel burner includes a main axis, a backflow region, a fuel nozzle and an inflow region disposed along the main axis between the fuel nozzle and the backflow region. A swirl flow of fuel can be generated in the inflow region. The backflow region has an annular gap adjacent the inflow region which narrows in the direction downstream of the inflow region and merges into a backflow conduit. An oil burner for a gas turbine uses the fuel nozzle configuration and a method is provided for regulating the fuel supply of a fluid-fuel burner.

Abstract: The present invention relates to the use of 8-iso prostaglandins and their derivatives for decreasing intraocular pressure, for example in the treatment of glaucoma It is based, at least in part, on the discovery that 8-iso prostaglandin E.sub.2 effectively decreased intraocular pressure by a trabecular meshwork outflow mechanism.

Abstract: A pair (1) of socks or stockings (2,3) may be joined together in a detachable fashion using a set heat-resistant, transparent fastening elements (4,5), in order to avoid sorting of the socks or stockings, e.g., after washing. Each of said fastening elements is firmly attached to a stocking or sock, preferably at its leg portion (6), in an area of the sock or stocking having a mesh density of at least 2000 MD, preferably at least 4000 MD.

Abstract: A burner configuration includes approximately concentrically disposed annular conduits for delivering various operating media. A plurality of outlet nozzles admix a gaseous medium or a liquid medium in finely distributed form with an air flow flowing in an approximately conically tapering outer annular-conduit air delivery system. A further annular conduit on an inflow side discharges into the annular-conduit air delivery system above the outlet nozzles.

Abstract: A heat shield configuration for structures carrying hot fluid, especially metal components of gas turbine systems and combustion chambers, includes adjacent mushroom-shaped ceramic material heat shield elements being mutually spaced apart defining expansion gaps therebetween, each of the heat shield elements having a surface-covering polygonal cap portion being flat or curved with straight or curved outer edges and a shank portion with an end facing away from the cap portion, the ends of the shank portions having beads formed thereon. A support structure on which the heat shield elements are anchored at a distance defines a space between the support structure and the heat shield elements to be subjected to fluid through channels formed in the support structure. Clamps secure the beads to the support structure and additional devices are provided for supporting the heat shield elements against the support structure.

Abstract: A hybrid burner has a main burner operable with premixing combustion and an auxiliary burner operable with premixing and/or diffusion combustion alone or operable to furnish a pilot light for the main burner. A fitting connects at least one hybrid burner to a main supply apparatus and an auxiliary supply apparatus. The fitting includes a change-over element. A main feed line communicates between the change-over element and the main supply apparatus, an auxiliary feed line communicates between the change-over element and the auxiliary supply apparatus, a main tie line communicates between the change-over element and the main burner and an auxiliary tie line communicates between the change-over element and the auxiliary burner. The change-over element is operable in at least one first and at least one second switching state. In the first switching state the main feed line communicates with the main tie line and the auxiliary feed line communicates with the auxiliary tie line.
