A slot die shim for use with a slot die, the slot die shim including a first channel configured to receive a first coating, a second channel configured to receive a second coating, and a third channel configured to receive a third coating. The slot die shim simultaneously dispenses the first coating through the first channel, the second coating through the second channel, and the third coating through the third channel onto a substrate. The coatings can be applied at different flow rates and include different test reagents. A vacuum force is applied to the first, second, and third coatings to control a width and a thickness of each of the coatings and a gap or distance between the coatings. The first, second, and third coatings are placed near one another or directly in contact with one another to minimize the area required for the coatings.

Apparatus and method useful for, among other things, providing a layer by layer coating of materials on a substrate.

The inventions relates to a method for producing a decorative workpiece with a structured surface comprising the following steps: (B) applying a first liquid lacquer having a coarse structuring over the entire surface, wherein a difference in thickness between thicker regions and thinner regions is at least 50 μm, in particular at least 100 μm; (E) applying a second liquid, at least partially transparent lacquer for producing a fine structuring in some regions. Furthermore, an apparatus for performing the method and a workpiece produced by the method are claimed.

The present disclosure provides a coating apparatus and method for applying a coating of a therapeutic agent, comprising an openable and sealable device compartment, a therapeutic agent positioned in communication with the device compartment, a thermal source for vaporizing the therapeutic agent, and a vacuum source in fluid communication with the device compartment.

A coating method includes a first step for spraying, onto an inner area of an opening part of a cylindrical body having a bottom and arranged horizontally, a first coating material of synthetic resin containing non-volatile components while rotating the cylindrical body around a central axis thereof. After the first step, a second step is performed for spraying, onto an inner area of a barrel part of the cylindrical body, a second coating material of synthetic resin containing a lower proportion of non-volatile components than that of the first coating material while continuing to rotate the cylindrical body. After the second step is performed and before the volatile components of the second coating material vaporizes, a third step is performed in which the rotation of the cylindrical body is stopped, the cylindrical body is placed vertically, and the volatile components of the second coating material are vaporized.

A substrate coating apparatus is disclosed. A substrate coating apparatus comprises: a source of a washcoat; a washcoat showerhead for discharging the washcoat towards an upper surface of a substrate; a conduit fluidly connecting the source of the washcoat to the washcoat showerhead for supplying washcoat to the washcoat showerhead; a headset for engaging the substrate to locate the upper surface of the substrate below the washcoat showerhead; and a vacuum generator for drawing the washcoat discharged from the washcoat showerhead through the substrate. The headset comprises a headset seal for engaging against the substrate. The headset seal comprises a perimetral portion that extends around the headset and a cantilevered portion that extends down from the perimetral portion and which is configured to engage against a sidewall of the substrate.

A extrusion process and apparatus for the deposition of precise, usually small amounts of extrudate (4) for adhesion to a substrate (1) comprising an extruder (2) positioned close to the substrate (1) and a jet of hot gas (6) directed onto the extrudate (1) between the extruder (2) and the substrate (1) in order to retain the adhesive properties between the extrudate (4) and the substrate (1).
