Abstract: Radically polymerizable dental material, which includes a catalyst paste and a base paste, wherein the catalyst pastes includes an oxidizing agent, preferably a peroxide or hydroperoxide, a radically polymerizable monomer and/or oligomer with acid group and a polyfunctional radically polymerizable monomer, and the base paste comprises a polyfunctional radically polymerizable monomer without an acid group and a dihydropyridine derivative of Formula (1) The material has good mechanical properties and does not exhibit a bitter taste.

Abstract: The present invention relates to cover for a medical injection device, said medical injection device having a hub portion defined at its distal end. The said cover includes an outer casing formed of a first material, said outer casing having a distal end and a proximal end,—an inner casing formed of a second material different from the said first material and defining a cavity capable of receiving in a sealing way, at least part of the hub portion, said inner casing having a distal end and a proximal end, and being at least partly inserted within the outer casing and at least partially in contact with the outer casing and—at least one substantially ring-shaped Radio Frequency Identification RFID tag embedded within the cover, said ring-shaped RFID tag including a RFID chip connected to at least one ring-shaped RFID antenna. The present invention also relates to a medical injection device and a method for manufacturing a cover.

Abstract: A closure for closing in a sealing manner a distal opening on a syringe body is provided. The closure includes a fastening element that is or can be arranged on the syringe body around the distal opening and a closure cap that can be loosely connected to the fastening element and closing in a sealing manner the distal opening. The fastening element includes an inner thread that intermeshes with an outer thread on the closure cap, resulting in an initial state wherein the outer thread is formed on at least part of the closure cap. The part is under tension in such a way that after the closure cap is unscrewed from the inner thread the part under tension is pressed out over the inner thread of the fastening element such that the closure cap cannot be returned to the initial state once the closure cap is unscrewed.

Abstract: Process for producing a tool insert for injection molding a microstructured part fabricated of a synthetic material, a metal or a ceramic material and which comprises an arrangement of microchannels and which further comprises an arrangement of through-going orifices extending in a substantially perpendicular manner with respect to the outer surface of the part.

Abstract: A method for forming highly defined and detailed micro-channeled components using injection molding of polymeric material is presented. Such micro-channel components can be created by holding the temperature of the injection cavity and mold in excess of the glass transition temperature of the polymeric material while the polymer is injected. The polymeric material can also be injected under pressure to facilitate the forming of the highly defined micro-features. The newly created polymeric substrate can then be ejected form the mold and used in micro-fluidic and other applications requiring precise and uniform micro-channeled structures.
