Abstract: A gas turbine engine is provided that includes one or more rotor assemblies, one or more shroud segments, and an actuator. The rotor assemblies are rotatable around an axially extending rotational axis, and each rotor assembly has a plurality of blades. Each blade has a blade tip. The one or more shroud segments each has a blade seal surface disposed radially outside of the one or more rotor assemblies. The blade tips and blade seal surfaces (collectively referred to as the blade seal surface) have mating conical geometries and a clearance distance extending between the blade tips and blade seal surface. The blade tips and blade seal surface are disposed at an angle relative to the axial centerline of the engine, which angle is greater than zero. The actuator is selectively operable to axially move one or both of the shroud segments and rotor assemblies relative to the other of the shroud segments and rotor assemblies to alter the clearance distance.

Abstract: Rear axle suspension system for motor vehicles, in which the wheel carriers on both sides are coupled to the body of the vehicle by at least one longitudinal link (9, 10), one transverse link (12) and a further transverse link (15, 16). In order to ensure that the axle kinematics distinguish between spring compression in the same direction and spring compression in opposite directions and a side force steering effect occurs, the transverse link (12) is a single connecting link which is connected to the two wheel carriers (3, 4) via first joints (5, 6) and connects both wheel carriers (3, 4), and the center of which (19) is guided, with respect to the body of the vehicle, in the longitudinal center plane of the vehicle, by a straight-guide (20 to 24). The straight-guide (20 to 24) is a Watt linkage (23, 24, 20).

Abstract: A gas turbine engine is piloted with a pilot flow of fuel delivered to a combustor as a liquid. A first additional flow of the fuel is also delivered to the combustor as a liquid. A second additional flow of the fuel is vaporized and delivered to the combustor as a vapor. A fuel injector may have passageways associated with each of the three flows.

Abstract: A switching power source device of resonance type is provided which comprises an output voltage detector 18 for detecting output voltage on a load 13 to produce a detection signal; and a control circuit 2 for applying on-off signals Vg1, Vg2 to each control terminal of first and second MOS-FETs 3, 4 in response to the detection signal from the output voltage detector 18. Control circuit 2 comprises a frequency control circuit 23 for controlling the on-off operation of first and second MOS-FETs 3, 4 in response to the level of detection signal from output voltage detector 18 to decide the switching frequency of first and second MOS-FETs 3, 4.

The tag has information thereon responsive to the identifier information. A computerized method of assisting the handling of a part, comprising the steps of: providing at least one computer; receiving part identifier information; processing the part identifier information; and generating output from the computer responsive to the part identifier information.

Abstract: A process for treating liquid hydrocarbon, includes the steps of providing a liquid hydrocarbon containing complex sulfur-containing compounds, providing a bioactive material selected from or derived from members of genus Alcaligenes; and exposing the liquid hydrocarbon to the bioactive material under effective conditions such that the bioactive material interacts with the complex sulfur compounds and transforms the organic sulfur-containing compounds into inorganic sulfur compounds.

Abstract: An electrophoresis apparatus 1 has an introducing passage 11 for allowing a sample to move from one end of the introducing passage 11 toward the other end thereof, and an analyzing passage 10, formed so as to cross the introducing passage in a cross-portion 8, for allowing a part of the sample in the cross-portion 8 to be separated from the other part of the sample in the introducing passage 11 to move by electrophoresis, wherein the angle between a downstream portion 10a of the analyzing passage 10 from the cross-portion 8 in an electrophoresis direction, and at least one of an upstream portion of the introducing passage 11 from the cross-portion 8 in a sample moving direction, and a downstream portion of the introducing passage 11 from the cross-portion 8 in the sample moving direction, is an acute angle.

Abstract: A method for forming an investment casting core comprises cutting a patterned core precursor from refractory metal-based sheet. The cutting forms recast along the cuts. An oxide is grown on non-recast areas. The recast is substantially chemically removed but substantially leaving the oxide. The core precursor may then be shaped.
