  • Patent number: 11000854
    Abstract: A rotor positioning device in a crusher is arranged to adjust a rotational position of a rotor shaft. A shaft engager includes a female toothed mating surface for coaxial engagement with a male mating surface at an end of the rotor shaft, so they become rotationally interlocked. The shaft engager includes alignable indicator slots that are, when in use, alignable with markings associated with an end of the rotor shaft, such that the markings become visible through the slots as the rod is rotationally driven by a drive component. The markings correspond to hammer positions within the crusher, such that these can be maneuvered for maintenance (e.g. to top dead-center positions) before access to the crusher chamber is gained.

  • Patent number: 10981205
    Abstract: An improved apparatus and method of fabricating long nanostructured or ultrafine grained tubes includes, in one implementation, expanding and extruding a sample material through cyclic deformations. The first cycle begins with expanding the sample through a die unit by applying pressure using a punch box, then with extruding the sample by applying back pressure using a stationary mandrel, which in turn reduces the expanded sample diameter to the original diameter. The next cycle begins with inverting the die unit to further extrude the sample with no need to apply back pressure. Furthermore, resistant forces against the sample are reduced by using a lubricant material inside the die unit, thus allowing continuation of additional cycles without constraining the sample length, resulting in desired strength and elongation.

  • Patent number: 10974296
    Abstract: A volume flow regulating valve for controlling the volume flow of a fluid medium in two outflow ducts. The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.
