Abstract: A system for cooling a hot rail of rail steel to a fine perlitic or ferritic or perlitic/ferritic structure has a plurality of separate cooling modules with independently adjustable cooling parameters. The rail is guided downstream through the modules of the cooling stretch and through intermediate zones between the modules so as to cool the surface of the rail in each of the modules and to subject the rail to destressing or stress relief between the modules. Sensors in each of the intermediate zones detect the actual surface temperature of the rail in the respective zones, and a controller connected to the modules and to the sensors varies the cooling parameters of the cooling modules in dependence on the detected temperatures in the respective upstream zones to ensure a defined temperature in the rail that lies above a critical temperature at which bainitic structure components are formed.

Abstract: A method for the adjustment of a gearbox actuation system of an automated gearbox of a vehicle. The gearbox includes a shift finger; a plurality of gearshift rails, each rail in the plurality of gearshift rails in a respective position; a neutral gap with a first portion formed by respective jaws for said each rail and with a second portion formed separate from the respective jaws and open to the first portion; and, a gearshift motor. The method includes the step of performing at least one reference travel with a gear in the automated gearbox engaged.

Abstract: In a parallel manual transmission, an upshifting under power is executed based upon preset operating conditions, for example with a fully depressed accelerator pedal, without an electronically controlled, load-reducing ignition retard. When shifting to a higher gear, the engine output is used for increasing the speed of the engine and for the propulsion of the vehicle, based upon the operating condition of the drive train.

Abstract: In order to obtain a fine-lamellar perlite structure in the edge region of the heads of rails (1), especially hot-rolled rails for carriageways or railways, by specific thermal treatment during cooling from the rolling heat without the formation of bainite, precooling (12) occurs in order to achieve a core temperature of approximately 750-850° C., and the temperature of the more intensively cooled edge region is raised by intermediate heating (13) to at least said core temperature and finally cooled (14).

Abstract: The invention relates to a method and device for monitoring brake signals in a vehicle with a gearbox control unit and engine control unit. An error recognition or a plausibility control of said brake signals is carried out. Brake light signals can be received by a gearbox control unit or an engine control unit. Brake light switch signals can be guided by a CAN bus. A cable break or defective contacts or a short-circuit can be considered as errors.

Abstract: A water box for a wire-rolling mill has a lower support and a lower plate carried on the lower support, extending horizontally below a path of a wire moving in a travel direction, and formed with an upwardly open groove extending parallel to and open toward the path. An upper support carries an upper plate formed with a straight groove. Respective upper and lower guide bars seated in the grooves of the upper and lower plates are formed with respective straight channels open away from the respective plates. A hinge connected between the supports permits movement of the upper plate between a closed position closely juxtaposed with the lower plate and with the channels confronting each other and forming a passage surrounding the path and an open position spaced upward away from the lower plate. In the closed position the wire is transversely enclosed by the channels.

Abstract: The invention relates to methods and devices for actuating a parking brake in a gearbox which is actuated in an automated manner, whereby gear changes are carried out by means of at least one electrically driven actuator, gear positions can be selected by means of a selector device, and the parking brake can be activated by means of the selector device when the vehicle is stationary or moving slowly. The invention also relates to a vehicle provided with an additional gearbox. The ignition key can only be removed, according to the inventive methods and devices, when the gearbox is in the P state and the additional gearbox is not in the N state. The invention further relates to a method and device, whereby the additional gearbox can only be shifted in the N state when the gearbox is not in the P state.

Abstract: A method of controlling a motor vehicle with an automated clutch is provided and includes the steps of: (a) detecting the vehicle speed, (b) detecting if the brake and/or the gas pedal is actuated, (c) detecting whether or not the engine is running, (d) disengaging the clutch if the engine is found to be running while the vehicle is found to be moving faster than a threshold speed, and if at the same time neither the brake nor the gas pedal is found to be actuated, and (e) subsequently re-engaging the clutch if the brake and/or gas pedal is found to be actuated. Prior to re-engaging the clutch, a transmission input rpm-rate is determined, and an engine rpm-rate is controlled in such a manner that that the respective rpm-rates of the engine and the transmission are brought towards a closer agreement.
