Abstract: Cultures of microorganisms can be grown in a body cavity by situating therein a nutrient on a suitable carrier while maintaining the nutrient exposed to a predetermined gaseous atmosphere, so that microorganisms which require a particular atmosphere can grow directly in the body cavity on the nutrient. After a time sufficient for culture growth the carrier with the nutrient thereon are removed from the body cavity and inspected, for example, under a microscope with suitable dyes being used to stain the growth for rendering the latter easily visible. The carrier for the nutrient may take the form of a plastic sheet material having small protuberances which are thicker than a nutrient layer carried by the plastic sheet material and which serve to maintain apart from each other surfaces of the plastic and nutrient which otherwise might engage each other to prevent exposure of the nutrient to the predetermined atmosphere.

This wedge member is formed with at least one opening situated at the heel region and extending downwardly from the midsole toward the outsole with the midsole and insole both having sufficient flexibility to extend at least partly into said opening in response to receiving the weight of the wearer of the shoe, so that the shoe can adapt itself to the shape of the foot of the wearer and contribute toward uniform support for the foot.

Abstract: In accordance with the process, a continuously fed viscoplastic material is subjected to a vacuum treatment in a thin layer with subsequent formation of a higher pressure zone from the material. Then the material is again subjected to the vacuum treatment in a thin layer, and a second higher pressure zone is formed from the material prior to feeding it to a next production stage. In an apparatus for carrying out the process for vacuum treatment, there is provided a container accommodating an auger having main and auxiliary turns running in opposite directions for feeding the material in a thin layer and for forming higher pressure zones from the material. There are provided a pipe in the container which is connected to a vacuum system for forming a vacuum zone in the container and means returning the material from one of the higher pressure zones back to the vacuum zone. The production process of vacuum treatment is thereby considerably accelerated and the material of better quality is obtained.
