Abstract: The invention relates to the grinding method with simultaneous homogenization of powder-like materials with liquid components in construction engineering, chemical and other industries. The roller breaker-homogenizer comprises a cone-shaped backing roll and not less than three driven rolls and driven rolls, the large bases of which face reverse directions. The rolls are arranged in the case with a replaceable cup vertically at the same level so that the driven rolls are located epicyclically relative to the backing roll and mounted in cantilever fashion in the case cover rotation bearing assemblies, and the backing roll is connected axially with a drive shaft via a spring coupling. An appliance used to regulate the spring coupling pressing force is mounted between the drive and spring coupling. The case cover has an opening for loading basic process materials above the upper end surface of the backing roll, and an anchor-type mixer is fixed on the lower end surface of the backing roll.

Abstract: Drainage belongs to medical equipment, particularly to medical tools and is specified for drainage of cavities. Drainage comprises a first tube, an additional tube, which is fixed upon it, a unit of the clot's splitter and the splitter's fixing element. The additional tube has a smaller diameter with an opening, inside which the conductor is mounted, a unit of clots splitter is installed on the working end of the drainage, it comprises a cylinder, a tube with an opening, placed on it, which is the continuation of the additional tube of the drainage and a spring with a cutter inside the cylinder. A cutter is located diametrically inside the working head, while in the end of the wall of the first tube and the splitter's unit comprises a channel, inside which splitter's fixing element was led, its working end is inside the unit's cylinder and fixes the splitter.

Abstract: An endoprosthesis utilizes a biomechanical structure based on the lever model of first degree. Contrary to the widespread practice, the inventive structure has a stem placed inside the femur bone, which is not rigidly attached to this bone. Accordingly, the bone, following its known tendency to slightly pivot away from the medial plane of the body in response to the loads, does not directly contact the stem. The neck portion experiences even greater loads then the stem. The supporting anchor has a region extending laterally from the stem and pressing against a supporting surface of the housing, which also extends laterally from the body of the housing. Since the stem, supporting anchor and neck are typically constitute a one-piece component, the lateral surfaces of the supporting anchor and housing are in continuous frictional contact during displacement of the stem and housing relative to one another.
