A roller for deflecting or guiding a metal strip to be coated in a metal melt bath may include bearing journals disposed coaxially with one another for rotationally supporting the roller. To obtain a high coating quality while hot-dip coating the metal strip, in particular steel strip, and to increase the service life of such a roller, each bearing journal may comprise a plurality of axially spaced annular elevations that have or are formed from a plain-bearing coating. The roller may comprise a steel roller shell, and each bearing journal may include a substantially cylindrical or circular-disk-shaped connecting steel portion that extends radially in the direction of the roller shell. At least one of the connecting portions may comprise a passage opening at an end face of the roller shell. The passage may be closed by means of a gas-permeable plug element comprised of ceramic material.

An alternating pressure melt impregnation device and a melt impregnation method, including having a resin melt squirted from each resin melt runner on an upper die and a lower die of a melt injection area, and thus the squirted resin melt is enable to be squirted directly on an upper surface and a lower surface of a continuous fiber bundle which is entering into an impregnation chamber. Impregnation and infiltration for both surfaces of the continuous fiber bundle are primarily completed by a squirted pressure. The resin melt inside the impregnation chamber flows to a decompression chambers at both sides of the impregnation chamber. When the resin melt flows to a throttle plate, a re-impregnation for the continuous fiber bundle is realized. Then the pressure is decreased and a section of the resin melt is enlarged and a radial flow is generated due to the Barus effect.

An intraocular shunt can be manufactured using a system that includes a liquid bath and a wire, which is moved through the bath. The wire can be moved through a first liquid bath to produce a first tubular layer of drug-infused gelatin. Further, the wire can be moved through a second liquid bath to produce a second tubular layer of drug-free gelatin. The first and second tubular layers can be dried on the wire in a humidity-controlled space, thereby manufacturing a drug-loaded gelatin shunt.

Devices and methods are provided for continuous measurement of an analyte concentration. The device can include a sensor having a plurality of sensor elements, each having at least one characteristic that is different from other sensor(s) of the device. In some embodiments, the plurality of sensor elements are each tuned to measure a different range of analyte concentration, thereby providing the device with the capability of achieving a substantially consistent level of measurement accuracy across a physiologically relevant range. In other embodiments, the device includes a plurality of sensor elements each tuned to measure during different time periods after insertion or implantation, thereby providing the sensor with the capability to continuously and accurately measure analyte concentrations across a wide range of time periods. For example, a sensor system 180 is provided having a first working electrode 150 comprising a first sensor element 102 and a second working electrode 160 comprising a second sensor element 104, and a reference electrode 108 for providing a reference value for measuring the working electrode potential of the sensor elements 102, 104.

A coating apparatus for continuously forming a coating layer on each surface of a substrate film includes a water tank located on a movement path of the substrate film, a water tank partition vertically located in the water tank, the water tank partition being configured to partition an inner space of the water tank into two zones, including a first water tank portion and a second water tank portion, a roller unit configured to continuously transfer the substrate film, and a heating unit located outside the water tank. The water tank partition is located spaced apart from an inner bottom surface of the water tank by a predetermined distance.

A device for coating material with resin and subsequently laying the material saturated with the resin onto a surface, the device comprising a vessel for retaining the resin, the vessel having a slot sized and configured so that the material is passable through the slot after being coated with resin retained in the vessel, and a first and a second roller being arranged on either side of the slot or behind the slot.

An optical fiber re-coating device of the invention includes an optical fiber coater that cures resin and coats a coating-removed portion of an optical fiber therewith. The optical fiber re-coating device includes: a resin reservoir tank that stores the resin which is before subjected to curing; a pump that supplies the resin stored in the resin reservoir tank to an optical fiber coater; and an air bubble separator that separates air bubbles included in the resin from the pump therefrom, sends the resin from which the air bubbles are separated to the optical fiber coater, and returns the resin including the separated air bubbles to the resin reservoir tank.
