Abstract: A method for aligning a cutter plate in a pelletizer for polymer pellets using a remote alignment adjustment device having a mechanical distance measurement probe and a camera for taking photos or videos. The remote alignment adjustment device is attached to the drive shaft of the cutter plate and rotates with the shaft to correct the alignment in different positions of the die plate. Additionally, a process for preparing polyethylene pellets in a pelletizer using the method for aligning the cutter plate.

Abstract: A layered semiconductor substrate has a monocrystalline first layer based on silicon, having a first thickness and a first lattice constant a1 determined by a first dopant element and a first dopant concentration, and in direct contact therewith, a monocrystalline second layer based on silicon, having a second thickness and a second lattice constant a2, determined by a second dopant element and a second dopant concentration, and a monocrystalline third layer comprising a group III nitride, the second layer located between the first layer and the third layer, wherein a2>a1, wherein the crystal lattice of the first layer and the second layer are lattice-matched, and wherein the bow of the layered semiconductor substrate is in the range from ?50 ?m to 50 ?m.

Abstract: A valve-type arrester includes a heat sink for dissipating heat from the interior of the valve-type arrester into the surroundings of the valve-type arrester. The heat sink has a circular-cylindrical main body with a base surface, a top surface parallel to the base surface and a casing surface connecting the base surface and the top surface. The heat sink additionally has a plurality of fins disposed on the main body, in which each fin is formed in the shape of a sheet or a leaf and disposed on the casing surface of the main body.
