METHOD FOR PRODUCING SPACERS FOR A WINDING UNIT AND VOLTAGE-RESISTANT SPACERS FOR CAST RESIN TRANSFORMERS
20250054690 · 2025-02-13 ·

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.

Apparatus for 3D-micro-patterning
20250078159 · 2025-03-06 · ·

Recently, we have introduced 3D-micro-patterned pharmaceutical dosage forms for enhancing the efficacy, safety, convenience, and cost-effectiveness of drug therapies. Presented herein is an apparatus for the manufacture of such dosage forms. The apparatus comprises at least a first extruder and at least a second extruder. The first extruder comprises an extruder channel having an exit port with a valve mated to an input port of a second extruder. Said second extruder comprises a translatable piston for extruding plasticized fiber at controlled speed. The apparatus further comprises a stage movable at the controlled speed of the extruded fiber for depositing said fiber to a three dimensional structural framework.
