Abstract: A ski locking device and method for securing a pair of snow skis equipped with snow brakes are provided. The ski locking device comprises a housing having a rear portion, and a lockable closure member connected to the housing. The housing and the lockable closure member are configured such that, when the ski locking device is in a closed position locking a pair of skis, with a slide surface of the first ski facing a slide surface of the second ski, the rear portion of the housing faces a first edge of the first ski and a second edge of the second ski. The lockable closure member encloses the snow brakes at a crossing point of the snow brakes.

Abstract: A ski locking device and method for securing a pair of snow skis equipped with snow brakes are provided. The ski locking device comprises a housing (1320) having a rear portion (240), and a lockable closure member (1370) connected to the housing (1320). The housing (1320) and the lockable closure member (1370) are configured such that, when the ski locking device is in a closed position locking a pair of skis, with a slide surface of the first ski (3010) facing a slide surface of the second ski (3020), the rear portion (240) of the housing (220) faces a first edge (3012) of the first ski (3010) and a second edge (3022) of the second ski (3020). The lockable closure member (1370) encloses the snow brakes (3040; 3050) at a crossing point (3060) of the snow brakes.

Abstract: This invention is concerned with the production of L-tryptophan by strains of Escherichia coli.The invention provides a host and method for growing that host such that plasmids can be stably maintained in the absence of antibiotics, leading to high productivity of tryptophan in fermentation. It offers significant improvements over previous methods and produces tryptophan free from any contamination by tyrosine an phenylalanine thus simplifying downstream processing.The E. coli strains having productivity for L-tryptophan comprise in their genome a mutant gene encoding a partially defective tryptophanyl-tRNA synthetase introducing a temperature-conditional tryptophan auxotrophy in the host and further mutations on the chromosome which disable the transport systems encoded by aroP, mtr and tnaB and being transformed with a plasmid containing a tryptophan operon encoding anthranilate synthase freed from feedback-inhibition by tryptophan.
