Abstract: A device serves for transplanting trees or shrubs. The device comprises a carrier that is capable of encircling the tree or the shrub. Circularly arced slideways are supported on the carrier, and spades are adjustably supported along the slideways. The spades can be adjusted from a digging position, in which they encircle the tree or shrub, to a transport position, in which they substantially complement each other to form a bowl. So that the spades can be easily adjusted, the slideways are accommodated in guide boxes. The guide boxes are supported on the carrier so that they can be adjusted independently of each other.

Abstract: A device for transplanting trees or bushes having at least two spades that can be adjusted against each other. These spades can be set between an open and closed position by means of a pair of attached servo-drives. When in the open position, the spades are removed from each other by a space corresponding at least with a diameter of the tree or the bush to be transplanted. When the spades are in their closed position, they complement each other, forming a partial spherical cup. To reduce the resistance of the spades as they penetrate the soil, the cutting blade of the spade has the shape of a corrugated ground edging. These corrugated ground edges have alternating elevations and recesses, whereby the elevations of the cutting blade provide sufficient stability and safety against breakage. The ground surfaces that oppose each other on these spades are disposed on alternating sides to allow the cutting blades to overlap.

Abstract: This invention relates to a process for the production of a usable or storable product with a low susceptibility to elutriation by water. This product is produced from residues containing halides obtained from a waste gas cleaning process. The halide containing residues as components of a crude dust having a CaO/SiO.sub.2 ratio between 1.7 and 3.4, are subjected to a thermal treatment to produce chlorosilicates. The waste gases formed during the thermal treatment for chlorosilicate production are subjected to a preliminary cleaning, and are then transported to the waste gas cleaning system of a refuse incineration plant. The residues occurring during the preliminary cleaning can be added to the crude dust.

Abstract: In a method of manufacturing sintered dolomite having raw densities exceeding about 3.0 grams per cubic centimeter in a shaft kiln from ground raw dolomite briquetted or pelletized into shaped bodies, the steps include deacidifying and heating the shaped bodies to a temperature of at least 1000.degree. C. in an upper region of the shaft kiln in a preheating and deacidifying zone heated with fuels of a low thermal content, thereafter sintering the shaped bodies in a lower sintering zone heated with fuels of high thermal content, so as to heat the shaped bodies to a temperature of about 1600.degree. C. to about 2000.degree. C., and subsequently passing the sintered bodies into a lower cooling zone, cooling the bodies therein, and, thereafter, discharging the sintered bodies from the shaft kiln.

Abstract: A tension shaft for machines for winding widths of sheet material wherein the outside diameter is variable is provided. The tension shaft includes a flexible tube wound thereabout in helical fashion which may be inflated by air fed into the central portion of the tension shaft. A valve for air feed discharge is provided to the central shaft. An air inlet from the central shaft to the flexible tube is provided. The air inlet is characterized by a screw member having an axial opening leading from the central shaft piece to a radial opening extending outwardly from the axial hole for directing air to the interior portion of the flexible tube.
