METHOD FOR PRODUCING SPACERS FOR A WINDING UNIT AND VOLTAGE-RESISTANT SPACERS FOR CAST RESIN TRANSFORMERS
20200357567 · 2020-11-12 ·

In a cost-effective and qualitatively better method for producing spacers for a winding unit of an electrical high-voltage device, at least two starting components are mixed together in a mixing chamber under vacuum to form a component mixture. The component mixture is transferred to an extrusion housing, likewise under vacuum, of an extruder in which a transport device is arranged and which is equipped with a mouthpiece delimiting an outlet opening. The extrudate exiting from the mouthpiece is cured by the addition of heat in a vacuum in order to obtain the spacers.

MOLDING PROCESS FOR JOINING PREFABRICATED WORKPIECE SUBSTRATES INTO A WORKPIECE ASSEMBLY

A method of joining a first workpiece substrate and a second workpiece substrate is disclosed in which a local mold tool is positioned into contact with the first workpiece substrate and the second workpiece substrate. The local mold tool defines a mold cavity and encloses an edge portion of the first workpiece substrate and an edge portion of the second workpiece substrate such that the edge portion of the first workpiece substrate and the edge portion of the second workpiece substrate are contained within the mold cavity. Once the local mold tool is positioned, a liquid polymer molding compound is injected into the mold cavity. The liquid polymer molding compound is hardened in the mold cavity into a polymer joint that adheres the edge portion of the first workpiece substrate and the edge portion of the second workpiece substrate together.

Microfluidic chip with anchored nano particle assembly

A microfluidic chip may include a substrate, chamber supported by the substrate, a sacrificial material in the chamber, a spectroscopically active nano particle assembly anchored within the chamber by the sacrificial material and a fluid supply port connected to the chamber. Each spectroscopically active nano particle assembly may include a cluster of nanoparticles.

METHOD OF PRODUCING POROUS MOLDED BODY

A molded body is produced from a molding material including a continuous phase and a dispersed phase by a three-dimensionalization step, a curing step, and a peeling step. The continuous phase of the molding material is a water phase containing a curable compound. In the three-dimensionalization step, the molding material is placed in a container. In the curing step, the curable compound is cured to form a cured product after the three-dimensionalization step. In the peeling step, the container and the cured product are separated after the curing step. In the dispersed phase removal step, the dispersed phase of the cured product is removed after the curing step.
