    摘要: The cooling-air ducting of the axial flow gas turbine runs in the area of the last blading stage (9+14) radially inwards of the heat-accumulation segments (23, 24) inside the outer boundary of the rotor (4) and through blade root channels (21) in the blade roots of the last moving blade ring (9) and finally through a cooling-air blade ring (28) fixed to the rotor into the diffuser into which the cooling-air flow enters with a velocity vector which essentially corresponds to the average velocity vector of the exhaust-gas flow entering into the diffuser. This avoids the flow losses which occur when the cooling-air flow passes out into the exhaust-gas flow in the area of the last stage or stages. At the same time, the temperature difference between the rotor circumference and the last rotor disk (4), likewise cooled by tapped air from the compressor, is in this way reduced, as a result of which the thermal stresses in the rotor are also reduced.

    摘要: A flange connection for round waveguides achieves a high-accuracy coaxiality of two round mutually adjoining waveguides (1a, 1b) by means of a radially elastic centering ring (3). The flange connection comprises two independent flange rings (2a, 2b) which are in each case attached to one end of the waveguides (1a, 1b), in which arrangement they are attached so as to be undisplaceable in the axial direction for a construction of the flange connection but to be freely rotatable around the respective waveguide. According to a preferred embodiment of the invention, the flange rings (2a, 2b) are constructed in such a manner that the flange connection can be joined in the manner of a bayonet lock.

    摘要: In a process for the sampling of an electric signal changing over time, an electron beam (12) is deflected laterally and linearly over time and at the same time modulated in its intensity according to the instantaneous amplitude of the electric signal. The electron beam (12) generates on a fluorescent screen (14) a brightness-modulated bar of light, which is preferably sampled with a sensor (15) arranged ahead of the fluorescent screen (14) in the form of a CCD line camera having a linear array of sensor elements (15a, b, c).The read-out analog sampled values of the sensor (15) are subsequently digitized and further processed.The advantage of the process is its high broad-bandedness and resolution and the capability of being able to carry out an averaging without additional expenditure of time.

    摘要: The resonance atomizer (4) of the burner facility has, as main components, a resonator ring (16) and a resonator cone (23), which each have an annular groove (25+24, respectively), which together form a resonance chamber (24+25). By a plurality of spacer strips (26) on the resonator ring (16), the resonator ring (16) and the resonator cone (23) are held apart by a distance which creates an annular inflow duct (27) for the oil/atomizing air mixture and outflow ducts (28) on the combustion space side for this mixture atomized in the resonance chamber (24+25). Between the components (16, 23) forming the resonator chamber (24+25) and the oil nozzle (7) there is an atomizing cross (17) with a baffle plate (19).

    摘要: The high-power radiator comprises a discharge space (12) bounded by a metal electrode (8), cooled on one side, and a dielectric (9). The discharge space (12) is filled with a noble gas or gas mixture. Both the dielectric (9) and the other electrode situated on the surface of the dielectric (9) facing away from the discharge space (12) are transparent for the radiation generated by quiet electric discharges. In this manner, a large-area UV radiator with high efficiency is created which can be operated at high electrical power densities of up to 50 kW/m.sup.2 of active electrode surface.

    摘要: Blading for a rotating thermal machine consists of an airfoil (1), a root (4) and a shroud plate (5) or a shroud, the tip (2) of the airfoil (1) having a spigot-type step (11) with a semi-circular groove (12) extending around the whole periphery of its generated surface. The shroud plate (5) or the shroud has a recess corresponding to the step (11) with a semi-circular groove (8) extending around the complete periphery. At least one piece of a firmly seated heat-resisting wire (10) is located in the circular duct formed by the grooves (8, 12) as the fastening element between the components (1, 5). The blading is manufactured by pushing and/or pulling the wire (10) sideways into the duct formed by the grooves (8, 12). Optimum material combination, particularly for highly loaded gas turbine blading, is possible by selecting an oxide-dispersion-hardened superalloy with longitudinally directed columnar crystals for the airfoil (1) and a non-oxide-dispersion-hardened cast or forged superalloy for the shroud plate (5) or the shroud.
