Abstract: A premix burner for a heat generator has partial cone shells (5) which make up a vortex generator, and which encompass a conically widening vortex chamber (6) and mutually define tangential air inlet slots (7), and also with feeds for gaseous and/or liquid fuel, of which at least one is arranged along the air inlet slots (7) on the partial cone shells (5), and at least one other is arranged along a burner axis (A) which centrally passes through the vortex chamber (6). At least n partial cone shells (5) encompass the vortex chamber (6), and define n air inlet slots (7), with n?3, preferably n?5, the n air inlet slots (7) each have at least a maximum slot width (10) which is equal to or larger than that slot width (10) which a generic type premix burner (1) of the same size and dimensioning with m?2 partial cone shells (5) and m air inlet slots (7) has.

Abstract: An optical droplet sensor can include a light emitter, a light receiver and a light guide, and can be adhered onto an inner surface of a windshield via a light transmissive adhesive layer. The light guide can include a light entry surface and a light exit surface formed of respective convex-shaped arbitrary curved surfaces, a light entry/exit surface formed of a flat plane, and a reflecting surface that can be made of a metal film. The light emitted from the light emitter is given an optimized light distribution at the light entry surface and introduced into the light guide. The light is then reflected from the metal film-applied reflecting surface toward an outer surface of the windshield. The light totally reflected at the outer surface returns to the light exit surface and is given an optimized light distribution at the light exit surface. The light is then externally transmitted/released from the light guide and collected on a light-receiving surface of the light receiver.

Abstract: In a process for producing leaves (20, 20?) for a leaf seal, in particular as a seal for a gas turbine, which leaves (20, 20?) are laterally delimited by a peripheral edge contour and have regions of different thicknesses (d1, d2), a simplification, without sacrificing precision, is achieved by virtue of the edge contour of the leaves (20, 20?) being cut out of a metal sheet (28) by an etching process and the regions of different thicknesses (d1, d2) also being produced simultaneously as part of the etching process.

Abstract: In a connection arrangement (10) for the stator winding of a turbo machine with two or more parallel circuits of individual conductors (26, 29) per phase, the individual conductors belonging to one phase form a phase group (25, 28) and run directly adjacent to one another in the stator body, the individual conductors of the winding are each connected from a winding connection (21, . . . , 24) to an external connection (15, . . . , 20) via a phase ring (32), which runs concentrically with respect to the machine axis (33). A simplification of the manufacture and assembly as well as a reduction in space requirements and an improvement in the thermal properties are achieved by the phase rings (32) of a phase group each being led together as a phase ring group (11, . . . , 14) from the winding connections (21, . . . , 24) to the external connections (15, . . . , 20).

Abstract: A steam turbine (10) having an inner casing (11), in which a rotor (12) that can rotate about an axis (13) is arranged, a steam passage (14) being formed between the rotor (12) and the inner casing (11), in which steam passage there is a multi-stage arrangement of guide vanes (16) secured to the inner casing (12) and rotor blades (17) secured to the rotor (12), in which arrangement hot steam coming from an inlet (15) undergoes work-performing expansion. In a steam turbine of this type, the thermal loading of the rotor and/or inner casing, in particular when starting up, is reduced by virtue of the fact that at least in the steam passage (14) plate-like protective shields (18, 19, 20), which protect the surface of the rotor (12) or inner casing (11) beneath them from the direct action of the hot steam flowing through the steam passage (14), are arranged parallel and close to the surface of the rotor (12) and/or parallel and close to the inner surface of the inner casing (11).

Abstract: A vehicle light can be configured to reduce the difference between the cut-off line of the actual light distribution pattern and the cut-off line of the designed light distribution pattern. The vehicle light can include a light source, first reflectors configured to reflect light from the light source, corresponding second reflectors configured to reflect light from the respective first reflectors, and a support member configured to support the light source. The support member and the first reflectors can be separately formed. Furthermore, edge portions configured to form cut-off lines in the light distribution pattern by the second reflectors can be provided in the support member instead of in the first reflectors.

Abstract: In a combustor (1) for a gas turbine, the combustor (1) includes a burner system (2) and a fuel supply system (3). The burner system (2) includes at least two burner groups (A, B) each with at least one burner (5). The fuel supply system (3) includes a main line (7), which is connected to a fuel source (8), and also an auxiliary line (9) for each burner group (A, B). Each auxiliary line (9) is connected to each burner (5) of the associated burner group (A, B) and is connected to the main line (7) by a controllable distribution valve (10). A sensing system (11) measures pressure pulsation values and/or emission values for each burner group (A, B). A control system (12), in dependence upon the pulsation values and/or the emission values, controls the distribution valves (10) so that in each burner group (A, B) the pulsation values and/or the emission values assume and/or fall below predetermined threshold values.

Abstract: A vehicle lamp can include a plurality of light source modules each having an LED as a light source, and optical systems for distributing light from each of the light source modules frontward toward predetermined areas or predetermined patterns that are different from each other and which make up a light distribution pattern. Each of the optical systems can be optimized to emit light to a predetermined area, and each of the light source modules' LEDs can be optimally arranged for each of the corresponding optical systems.

Abstract: Disclosed is a key sheet efficiently diffusing local heat generated by a device mounted on a board. A key sheet has a base sheet formed of a rubber-like elastic material in which a heat conductive filler is mixed. Thus, if a semiconductor device on a board generates heat, it is possible to suppress local heat storage by the heat conductive filler of the base sheet. Further, there is no need to provide a separate member for heat diffusion between the board and the key sheet, making it possible to realize a reduction in thickness. Thus, with the key sheet, it is possible to meet the requirement for heat diffusion to eliminate local heat storage in electronic apparatuses, and the requirement for a reduction in the thickness and weight of electronic apparatuses.

Abstract: An electrical machine (10) has a built-in stator (11) which is mounted in a housing (12, 13, 14) by a built-in stator suspension, in particular in the form of a plurality of supporting rings (29) which are arranged one behind the other, at a distance apart, in the axial direction and surround the built-in stator (11), which housing (12, 13, 14) surrounds the built-in stator (11) at a distance from it, with additional apparatuses (38, 39) being provided in order to fix the housing (12, 13, 14) relative to the built-in stator (11) and with respect to the built-in stator suspension (29). In a machine such as this, the housing oscillations are minimized without any deterioration in the robustness that is required for transportation in that the fixing apparatuses (38, 39) are apparatuses which can be adjusted from outside the housing (12, 13, 14).

Abstract: A projector type vehicle light can provide an improved far distance visibility in a highway mode and other improved headlight performances by switching the low beam distribution and the highway mode light distribution while utilizing AFS functions. The projector type vehicle light can include a first lamp unit and a second lamp unit. The first lamp unit includes a light source, a reflector, a projection lens, and a light-shading member, and is configured to reflect light from the light source by means of the reflector and project light in the forward direction by the projection lens. The second lamp unit can have almost the same configuration as the first lamp unit and is located adjacent to the first lamp unit and either above or below it. The cut-off line formed by the first lamp unit can be located at an angular position below the horizontal line by 0.57 degrees in order to form a low beam distribution for an ordinary road.
