Abstract: The fermentation plant for the biological degradation of organic material and for the collection of the bio gas formed during degradation has a closed container with a filling opening for fresh material and inoculated material and discharge openings for the degradation products as well as a stirring device for mixing the fermentation material. The stirring device has circularly moving stirring blades which are preferably individually driven in the container. Scrapers are provided on the container floor with which heavy precipitates deposited on the container floor are transported in batches to a discharge device. A flow system for a heating medium is also provided on the side walls which is optionally divided into several heating circuits to vary the temperature at various sectors of the heating surface.

Abstract: Dual-chamber pressurized dispensers for a variety of products. A flexible inner container defines one chamber in which the product to be dispensed is contained, the inner container being connected at one end to a dispensing valve. A rigid outer container encloses the flexible inner container and therebetween defines another chamber in which a pressurizing propellant is contained. Each inner container is designed to achieve high expulsion efficiency, with an upper portion having a lipped aperture in which the dispensing valve is received and a lower portion having longitudinal stiffening ribs.
