Method and device for freeze drying solutions and liquid containing solid substances, in which a vessel (1) is applied having a downwardly conical shape with inside a rotating mixing member (3) that moves with a small inter-space along the wall (2) of the vessel. With the new method in an advantageous manner free flowing products are obtained. Even new homogenous mixtures of a molecular scale of two or more substances are obtained, which are excellently usable in the industry of new materials.

A device for mixing of particulate material comprises a conical mixing vessel having a vertical axis, which vessel narrows in a downward direction and in which vessel at least one vertical mixing shaft is rotatable. A number of radial elements project from the mixing shaft, and carry paddles at their distal ends, adjacent the sidewall of the vessel. The radial elements are long and thin, while the mixing paddles are relatively short and are symmetrical round the axis of the elements. Due to the rotating paddles and the conical shape of the vessel, the contents move spirally upwardly. The layers of material closest to the wall end to have less spiral and more upwards movement, so that the intermediate layer is subjected to strong shearing forces that promotes mixing. A chopper is mounted in the top of the said vessel for chopping material in an upper portion of the vessel, above said mixing paddles.

The deodorization block is applied in toilets. The deodorization block comprises a relatively small amount gas developing substance and perfume and is provided with an easily to open moisture resistant envelope. After elimination of the easily to open envelope the deodorization block is deposited in the toilet bowl, preferably prior to each use of the toilet.

The invention relates to a concrete pavement tile, which produces a clearly recognizable sound when touched with a blind's cane or a white stick. In practice it appears useful to incorporate sound sources in guide paths for the blind. The invention has solved this problem by providing a pavement tile (1) with an upper plate (3) of metal, which is supported by the tile at its circumference. The plate can be provided with regularly distributed outwardly projecting tears, bumps or ledges (6). Below the plate there is a sound space (2) which can be formed by pressing the plate, upwardly convex, whereas a hollow executed tile give the same effect.

The invention relates to a safety device for occupants of road or water vehicles. There are emergency situations in which the occupants cannot leave the vehicle, for example when it has hit the water and has flooded completely or partially, or when the interior of the vehicle is filled with smoke and combustion gasses and the occupants are at risk of drowning or suffocating. The invention is characterized in that said device offers the occupants of the vehicle the possibility to administer themselves of oxygen in an easy way during emergency situations, or any other moment and at the same time breathe in as little as possible, smoke and combustion gasses possibly present.

The invention relates to sail cloths for producing sails for sailing ships, in order to obtain radar reflection from the sails when the sailing ships cruise at sea, according to the invention a number of electrically conductive elements (14) are included in the sail cloth structure. These conductive elements (14) can for instance be formed by metal foil, and/or conductive polymer foil and/or metal wire elements. These elements (14) can be fastened by either gluing, stitching or plasma torch action. The invention also relates to a method and apparatus for producing radar reflecting sails.
