An apparatus including a first device which moves a first portion of a soft, damp, slightly pressed slab out of alignment with a majority of the slab and thus introduces a first crack in the slab; and a device for spraying a first colored material into the first crack of the slab. The first device which moves the first portion of the slab out of alignment with the rest of the slab may include a first cylinder. The device for spraying the first colored material in the first crack of the slab may include a robotic apparatus. In at least one embodiment, the apparatus may also include a second device which moves a second portion of the slab out of alignment with the majority of the slab and thereby introduces a second crack in the slab.

A coating pattern formation method includes adjusting lyophilicity of a pattern region provided on a substrate, and forming a coating pattern having a shape of the pattern region by applying a coating liquid to the pattern region after the adjusting of the lyophilicity of the pattern region. The lyophilicity of the pattern region is adjusted such that the pattern region is divided into a plurality of small pattern regions in at least one division direction, such that adjacent small pattern regions have different lyophilicity, such that a small pattern region spaced away from an end of the pattern region has the lowest lyophilicity among the small pattern regions in the at least one division direction, and such that the lyophilicity of the small pattern regions increases from the small pattern region having the lowest lyophilicity toward the end of the pattern region.

A dispenser comprises: a nozzle having a nozzle hole; a connector to which the nozzle is coupled; a syringe detachably coupled to the connector, having a space in which the ink is contained, and provided with a plunger; and a tube assembly to which the syringe is detachably coupled and which injects air that moves the plunger, into the syringe.

Described herein is a method for producing a sealant. The method includes mixing a first material with a second material at a manufacturing site to produce the sealant. The method also includes applying x-ray energy to the sealant at the manufacturing site. The method includes measuring an amount of fluorescence emitted from the sealant in response to applying the x-ray energy. The method also includes calculating a mix ratio of the first and second materials of the sealant based on the amount of fluorescence. The method includes determining whether the mix ratio is within a predetermined mix ratio range.

The robotic device conducts an action on a curved ferromagnetic surface. The robotic device includes a chassis platform and at least one magnetic side drive module. The chassis platform rolls on the curved ferromagnetic surface and is maintained thereon by virtue of the curved ferromagnetic surface being ferromagnetic. The at least one magnetic side drive module is pivotally attached to the chassis platform and is for conducting the action on the curved ferromagnetic surface as the chassis platform rolls on the curved ferromagnetic surface.

A method and system for powder coating non electrically conductive elements, preferably brake pads. A pre-treatment station is upstream of an electrostatic powder coating deposition station and a baking station for melting and polymerizing the powder coating in order to form a coating layer on a surface to be coated. The pre-treatment station causes the elements to be coated to conduct electrically by uniformly wetting said elements by means of creating poorly mineralized water covalent bonds on at least one surface to be coated, in an amount aimed at producing a measurable weight increase in the non electrically conductive elements, which then causes them to conduct electrically. The water adsorbed and/or deposited is subsequently eliminated within the baking station.

A device (4) for applying a viscous liquid, in particular an MFC dispersion, onto a moving substrate (52) comprises an inlet (72, 73a-73f) for the viscous liquid, a casting chamber (61a, 61b), a lower portion of which being open to the substrate (52), and a metering portion (69, 661), for limiting a thickness of a wet film that is formed on the substrate downstream of the device. The device further comprises a shear section (42) arranged inside the casting chamber (61a, 61b). The shear section (42) comprises a fluidization rod (68), arranged in the casting chamber (61a, 61b), for providing shearing of the viscous liquid inside the casting chamber (61a, 61b).
