Abstract: The invention relates to an isolated polynucleotide having a polynucleotide sequence which codes for the alr gene, and a host-vector system having a coryneform host bacterium in which the alr gene is present in attenuated form and a vector which carries at least the alr gene according to SEQ ID No 1, and the use of polynucleotides which comprise the sequences according to the invention as hybridization probes.

Abstract: The present invention relates to a method and a measuring device for measuring and displaying the overlap between a rear edge of an aircraft wing and a front edge of a landing flap fixed thereto. In accordance with the invention, only the difference in the positions of the rear edge of the aircraft wing and the front edge of the landing flap relative to the longitudinal direction of the aircraft is determined. For this purpose, a first sensor is positioned, as a reference of sorts, at one of the two positions, for example at the rear edge of the aircraft wing, and the display is then reset to zero or to another reference value. By positioning the second sensor, which is also rigidly connected to the calliper, at the other respective position, for example at the front edge of the landing flap, the difference between the front edge of the landing flap relative to the rear edge of the aircraft wing is established.

Abstract: An apparatus for opening a door of a climatic test cabinet, an incubator, an environmental simulation chamber or a freezer is suitable for unlocking the door when the door is closed and locked and for transferring it to an open position. The force for opening the door need no longer be applied by the user himself operating lever mechanisms and transferring the door to an open position, but instead the force for opening the door may be applied by the apparatus.
