There is described an illumination unit with a planar carrier part having a plurality of light-emitting semiconductor components, in particular high-power light-emitting diodes, arranged on both sides of a main surface. On each side of the carrier part a heat sink is provided in each case. Each of the semiconductor components is connected in an efficient heat-conducting manner to a heat sink provided on an opposite side of the carrier part by way of a heat conducting means that is fed through an opening in the carrier part. At least one reflector is embodied on each heat sink having a reflective surface which concentrates the emitted light from a semiconductor component which is arranged on the side of the carrier part facing this heat sink.

A method relates to manufacturing contact spring sockets with a plurality of contact springs, clamped at one end in an approximately cylindrical thin-walled socket body and bowed radially inward. The straight contact springs are introduced in the socket body into the annular space between a mandrel and the socket wall and subsequently when in an aligned state relative to each other are pressed against an annular head at the front end of the line connector which partly projects into the socket body and are made fast in this position at one end. Deformation of the socket body for elastically bowing the contact springs can be omitted according to the invention, if after introduction of the contact springs into the annular space of the socket body an insert ring (10) is introduced into the latter fitting adjacent the socket innner wall, whose internal diameter is smaller than the external diameter of the annulus plus twice the diameter of the contact springs. By these means the insert ring with its inner end edges presses radially inward on the contact springs. At their ends away from the pin insertion opening they are pressed radially outwards by the subsequent introduction of the conically formed front end of the line connector, before they are made fast by clamping and folding over of the socket edge against the connector.

Positionable deflector means are provided in a gas turbine engine inlet duct. The deflector means are actuated to change the axial and circumferential location of a forward protruding extension of the inlet duct in order to selectively reduce noise propagation. A method is disclosed for directional noise shielding as a gas turbine engine experiences altitude and operational changes.

Variable geometry guide vanes are provided in a variable pitch turbofan assembly. A method is disclosed for reducing aerodynamically induced stresses in the variable pitch fan blades as the blades are changed between the forward and reverse pitch modes. The guide vane geometry is scheduled to change in a manner to control the flow into and out of the fan blades in order to establish a favorable aerodynamic environment during the transition between the forward and the reverse pitch modes.

A device for detecting the angle of rotation of a throttle valve operated by an electric motor is disclosed. The valve is rotatably supported on a throttle valve shaft in an intake system of a throttle valve housing, wherein an actuator motor coupled to the throttle valve shaft predefines the throttle valve angular position in a manner controlled by a control unit, and wherein a predetermined value of the throttle valve angular position is predetermined by a manually operated predetermined-value input apparatus and is fed to the control unit. The predetermined-value input apparatus is coupled to a predetermined value sensor shaft, wherein the angular position of the predetermined value sensor shaft corresponds to the manually predefined predetermined value of the throttle valve angular position.
