  • Patent number: 11919507
    Abstract: A method for controlling a motor vehicle having at least one park lock. A drive train of the motor vehicle has a drive motor, wheel, and a transmission. An operating element actuates the park lock, which can assume a blocking position, in which the park lock blocks the drive train and/or a part of the drive train, and a release position. After actuation of the operating element, the park lock is switched from the release position into the blocking position (or vice versa). Here, the speed of the motor vehicle is determined. After actuation of the operating element and if the park lock assumes the release position beforehand, it is checked whether the speed is greater than a predefined first threshold value. If this check was successful, a first warning signal is produced; and the switching of the park lock into the blocking position is performed.

  • Patent number: 5545784
    Abstract: Molecular sieves are modified by an ion exchange process where metal cations are introduced into the molecular sieves by means of solid state ion exchange. The solid state ion exchange can be carried out as follows: a weighed amount of calcined and activated zeolite is intimately mixed with a precalculated amount of PtCl.sub.2, PdCl.sub.2, RhCl.sub.3, CuCl.sub.2, V.sub.2 O.sub.5 or another compound of the noble metals (e.g., corresponding halides or oxides), the solids mixture is then heated in a current of inert gas (e.g., a current of helium gas or of nitrogen) to temperatures of 400.degree. to 600.degree. C., then cooled down to room temperature and subsequently reduced in a current of hydrogen for 10 to 14 hours at 280.degree. to 350.degree. C. in order to produce small metal clusters from the cationically introduced metal.

  • Patent number: 5166432
    Abstract: The present invention provides a process for the production of cyanamide from urea and/or decomposition products thereof at an elevated temperature with the use of a microporous catalyst, wherein, as catalyst, there is used a zeolite and/or a silicoalumophosphate which is doped with transition metal cations selected from the Group IB and VIIB of the Periodic System. In this way, it is possible to increase the conversion, referred to urea, to 60 to 100%, the selectivity with regard to cyanamide thereby being from about 30 to 50% and with regard to the undesired melamine being .ltoreq.2%.
