  • Arrangement for actuating a change-speed gearbox shift mechanism and for engaging and disengaging a main clutch
    Patent number: 5881853
    Abstract: An arrangement actuates the shift mechanism of a change-speed gearbox and engages and disengages a main clutch via a common servomotor.

  • Process for determining a desired load value for a load-dependent current generating system in an electric vehicle
    Patent number: 5877600
    Abstract: This invention provides a process for determining a desired load value for a load-dependent current generating system, particularly a fuel cell system, in an electric vehicle. Based on an accelerator pedal demand, a desired value for the motor line currents of the electric driving motor is determined in the driving motor converter, and therefrom a desired load value is generated directly for the current generating system.

  • Marking for painted objects and method of applying the marking
    Patent number: 5876809
    Abstract: This invention relates to a marking for painted objects, preferably motor vehicles, as well as to a method for producing the marking. For this purpose, a paint coat, preferably having several paint layers, is applied to the object and the spectral course of a partial spectrum of the electromagnetic spectrum of the paint coat arranged within an electromagnetic measuring range is changed in a targeted manner such that it has narrow-band extremes of at least 5% relative intensity change.

  • Method and apparatus for optimizing the aerodynamic effect of an airfoil
    Patent number: 5875998
    Abstract: A method and an apparatus are provided for optimizing the aerodynamic effect of the airfoil of an aircraft by defined changes in camber. The method includes the following steps:a. determining the flow for the flight condition caused by the change in camber,b. comparing the ascertained characteristic values with stored nominal reference values for an optimal flow,c. forming differential values between the characteristic values and the stored nominal reference values,d. deriving actuator signals from the differential values, ande. changing the camber by motor, based on the actuator signals, for minimizing the differential values.The optimum wing flow is thereby maintained more exactly. For transonic wings, the position and strength of compression shocks is also effectively controlled, which leads to a reduction of the direct shock induced separation.

  • Reading lamp system for passengers especially in an aircraft
    Patent number: 5873644
    Abstract: A reading lamp system for passengers especially in an aircraft is equipped with at least one central light source preferably including a cool light lamp, the light of which is supplied through light guides such as fiber optical conductors, to individual reading lamps having a housing to which the respective light guide is connected. A liquid crystal film is positioned in the lamp housing between the light exit of the respective light guide and a lens that provides a light output from the reading lamp housing. The liquid crystal film is controllable in its light transparency by a passenger through a switch, whereby the passenger can make the liquid crystal film opaque to switch off the reading lamp or transparent to switch on the lamp. A dimmer may also be arranged to provide intermediate light level illuminations.

  • Method and apparatus for combatting helicopters operating with concealment
    Patent number: 5874727
    Abstract: The invention provides a method for continuous acquisition, identification, and attack of helicopters operating with concealment, using a missile with an integrated target search head computer control. The visual field of the search head is adapted optimally in both the search phase and in the target tracking phase. During the search phase, the missile travels a flight path roughly parallel to the surface of the ground, and the axis of the line of sight is directed diagonally downward at a suitable angle. During a target tracking, the line of sight runs collinearly with the missile axis. The natural radiation of the helicopter modulated by the rotor blade movement is used for target recognition.

  • Control element arrangement for controlling the steering angle of a motor vehicle
    Patent number: 5873430
    Abstract: Control element arrangement for controlling the steering angle of a motor vehicle is provided. The arrangement has a user-operable control element by whose operation a steering angle adjusting unit can be controlled for the steering angle adjustment of the vehicle wheels which is mechanically uncoupled from the control element. A reaction force mechanism is provided for such an arrangement which exercises a reaction force onto the control element which counteracts the control element operating force and which rises when the steering angle size increases as well as when the longitudinal and/or lateral movement of the vehicle increases.

  • Method and apparatus for selective catalytic oxidation of carbon monoxide
    Patent number: 5874051
    Abstract: In a method and apparatus for selective catalytic oxidation of carbon monoxide, the gas mixture and an additionally added oxidizing gas are conducted through a reactor containing the catalyst. Oxidizing gas is added at several points along the mixed gas flow path with a controlled or regulated through flow volume. The mixed gas stream is cooled passively by static mixing structures located in the inlet area of the CO-oxidation reactor. By controlling exothermal CO oxidation along the reactor path, a very variable process guidance is provided, that can be adjusted to individual situations.

  • Fuel injection control system for a multi-cylinder internal combustion engine
    Patent number: 5868111
    Abstract: In a fuel injection control system for a multi-cylinder internal combustion engine including a high pressure fuel pump for supplying fuel under pressure to the fuel injection valves of the various cylinders through a distribution line including a fuel distribution element dividing the fuel supply to two groups of fuel injection valves, the fuel distribution element includes a piston disposed in a cylinder and adapted to interrupt fuel flow to any one of the two groups in which a leak occurs such that fuel supply to the other group of fuel injection valves can be maintained for an emergency operation of the engine. If small leaks are detected by the electronic engine operating control, the valves of one of the groups are momentarily deactivated to cause the distribution element to interrupt the fuel supply to the other group of fuel injection valves.
