The invention relates to a sensor element for detecting at least one analyte in a body fluid or in a body tissue, particularly for determining at least one metabolite concentration in a body fluid. The sensor element comprises an implantable, one-piece shaped body, which comprises a sensor end and a coupling end. The shaped body comprises, in the area of the sensor end, at least one sensor area, which comprises at least one sensor material. The sensor material changes at least one optically measurable property in the presence of the analyte. The shaped body also has at least one optically transparent coupling part, which is designed to transmit electromagnetic radiation in at least one spectral range between the sensor area and the coupling end. In the sensor area, the shaped body has at least one optically transparent matrix material, and the analyte can at least partially diffuse through the matrix material to the sensor material. The sensor material is embedded in the matrix material. The coupling part is formed at least partially by the matrix material.

The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.

A method of producing a brush for the cleaning of electronic components. In this method, a plastic core is prepared and submerged into a solvent to melt the outer surface of the core. While the outer surface of the plastic core is still partially melted, it is rolled through a trough of powdered polyvinyl alcohol (PVA) such that granules of PVA melt into and subsequently become embedded at the outer surface. As the solvent evaporates, the outer surface of the core re-hardens and the granules of PVA become firmly entrapped at the outer surface. The PVA covered shaft is placed in a mold, which is then filled with a PVA solution. As the solution cures, it forms a strong bond with the PVA granules that are embedded at the surface of the plastic core. Thereafter, the mold components are disassembled, leaving behind the finished cored brush.

A solid dose for insertion into the skin of a patient wherein the solid dose has a hollow core. There is also provided a solid dose carrier, a device, a method of manufacturing the solid dose and a method of delivering a solid dose transdermally to a human or animal.

The invention relates to a method for producing embedded hydrogel contact lenses each having an insert that comprises alignment features capable of capable of aligning the insert in depth and radial position in a female mold half during cast molding of an embedded hydrogel contact lens. The alignment features protrude from the front surface, are rotationally symmetric with respect to the central axis of the insert and independently have a shape having a curvature being greater than 2 folds of the curvature of the molding surface so as to minimize contacting area between the alignment features and the molding surface. The use of such an insert can simplify the process for producing embedded hydrogel contact lenses and enable the process to be implemented readily in an automatic production.

A cured object and a method for producing the same are disclosed herein. In some embodiments, the method of producing a cured object includes introducing a resin composition including a resin and magnetic powder into one or more slots of a tubular object, wherein the resin composition includes a resin and a magnetic powder, wherein the tubular object includes a penetration space and an edge region having the one more slots formed therein, and wherein the penetration space and the one or more slots are formed in a longitudinal direction of the tubular object; inserting a solenoid coil into the penetration space of the tubular object; and generating a magnetic field with the solenoid coil to cure the resin present in the one or more slots of the tubular object.

The cured resin object can also have excellent withstand voltage characteristics.

Systems and methods for casting solid propellants include a mandrel for forming geometric features in a perforation of a propellant grain. In various embodiments, the mandrel includes a frangible portion that is removed from the propellant grain after the propellant grain has cured around the mandrel. A second portion of the mandrel may be left behind in the propellant grain. The mandrel may include a support structured disposed in the through hole of the mandrel. The support structure may include a plurality of longitudinal channels for directed exhaust gasses through the mandrel upon ignition of the propellant grain.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.
