The wind turbine has two vaned rotors fitted on horizontal shafts (23) rotatably fitted in a bearing component (10). This component is connected to a rotatably located vertical output shaft (15). The rotor shafts project radially on diametrally opposite sides of this shaft. The rotor shafts have gearwheels (25) for engagement with a gear ring (26) coaxial with the output shaft. - The bearing compo...

The present invention relates to compositions for making sealing walls, dump linings and the like, especially barriers placed in the ground. The compositions contain expandable clay minerals, cement and fillers in aqueous suspension, as well as additives of alkali metal aluminates and alkoxy alkylsilanes. On the basis of these additives, the sealing action against water and pollutants is substanti...

Polypeptides with a carboxamide carboxyl terminus and a methionine residue, which is optionally bound to a bacterial protein, at the amino end can be prepared by genetic engineering synthesis of the corresponding polypeptide with a glycine residue at the C terminus and the enzymatic conversion thereof into the amino group of the required carboxamide moiety. Peptides which have the amino-acid seque...

The propulsion arrangement comprises a force propeller (1) and a rear propeller (7) which counter-rotate relative to one another. The two propellers are supported on the vessel (3) at such a distance (L) from one another, viewed in the longitudinal direction of the ship, and with the rear propeller working in the flow field (8) of the forward propeller, that a gap (9) is formed between them. The r...

Door for the front of a vault, such as a bank vault, for storage of objects of value, comprised of a door leaf (1), of which the interior framework is equipped with at least a lock (17, 18), bolts (15) and least one locking mechanism (29) for locking the said bolts. A tempered glass device is located (14, 14', 14'') on the exterior in relation to lock and this locking device connected to the inter...

A device for preventing the removal of a so-called manhole primarily at the door of a vault for storing valuables, such as a bank vault. The door consists of a door leaf (1) on the inside of which a locking mechanism with a lock, lock cylinders (15) and mechanisms for controlled displacement of the aforementioned lock cylinders between a locked and unlocked position of the door from the outside (4...
