Abstract: The present invention relates to a molecular biological method for the specific detection of mycobacteria and for the differentiation of the Mycobacterium tuberculosis complex and Mycobacterium avium from other mycobacteria in clinical material by means of amplification primers and oligonucleotide probes which are specific for the genus- and species-specific regions of the 16S rRNA gene of mycobacteria.

Abstract: A device for discharging cream or paste like material from a container, comprising a treat-like sleeve of a resilient material which has a mechanism for securing on an outlet on the container. The sleeve is intended for being provided in a depending position on the container. Inside the sleeve in the upper portion a body is provided, which is designed to be forced towards the container in case of an increase of pressure in the cream or paste-like material in the sleeve, and which is, via an elongated member, connected with the valve member at the lower end of the sleeve, the valve member cooperating with a discharge opening at the lower end of the sleeve. The body is dimensioned to be guided by the container outlet or another opening connected to the latter. A passage is provided through the body with an outlet opening inside the sleeve. A check valve is provided inside or near the channel or the passage.

Abstract: Device for a safety helmet with ear mufflers, where each ear muffler is mounted on an arm which is mounted on the helmet pivotally in a plane parallel to the longitudinal direction of the helmet. The mufflers with arms are also pivotal in a plane across the longitudinal direction of the helmet, adjustable from a noise-deadening position where the mufflers are against the ears, to an out-swung and stopped position.
