A co-axial roller printing equipment includes a working platform, a roller, a grinding device, a cutting device and a coating structure. The working platform is configured for carrying a substrate and driving the substrate to move. The roller is disposed above the working platform and has a surface. The grinding device is disposed on the working platform and configured to contact and grind the surface of the roller. The cutting device is disposed on the working platform and configured to cut the surface of the roller to form a plurality of relief structure. The coating structure is configured to receive a slurry and coat the slurry on the relief structures. Wherein, the grinding device and the cutting device grind and cut the surface of the roller in sequence; wherein, the coating structure coats the slurry on the relief structures, then the roller prints the slurry on the substrate.

Moving an article after a material, such as a hot-melt adhesive, has been applied to a surface of the article is accomplished with an article transfer apparatus. The apparatus is comprised of a belt having a plurality of apertures extending there through that are effective to communicate a vacuum pressure from an inner surface of the belt to a contacting surface of the belt. The vacuum pressure secures and adheres the article to the contacting surface of the belt as the belt conveys the article. The vacuum pressure is distributed along the inner surface of the belt by a vacuum chamber, which is between a compression roller and a second roller.

To address technical problems facing silicon transient thermal management, a thermal interface material (TIM) may be used to provide improved thermal conduction. The TIM may include a liquid metal (LM) TIM, which may provide a significant reduction in thermal resistance, such as a thermal resistance R.sub.TIM≈0.01-0.025° C.-cm2/W. The LM TIM may be applied using a presoaked applicator, such as an open-cell polyurethane foam applicator that has been presoaked in a controlled amount of LM TIM. This LM presoaked applicator is then used to apply the LM TIM to one or more target thermal surfaces, thereby providing thermal and mechanical coupling between the LM TIM and the thermal surface. The resulting thermal surface and thermally conductive LM TIM may be used to improve thermal conduction for various silicon-based devices, including various high-power, high-performance system-on-chip (SoC) packages, such as may be used in portable consumer products.

A Robotic Coating System with Real-Time Mixing has a particular arrangement of a robotic gantry, two peristaltic pumps, a mixer, a hollow brush, two tanks, and a computerized controller. The invention has tubes providing fluid communication from a coating tank and a thinner tank through the pumps and mixer to the brush. The invention provides everything necessary for robotic coating in one compact system. This invention provides the ability to apply coatings to an item, without pre-mixing the coating components. A computerized controller drives the brush through a pre-programmed path to coat required areas and not coat sensitive areas. The System operates upon utility service, typically 110 VAC, and it also self-cleans.

A method and apparatus for applying a viscous fluid onto a surface. An applicator associated with an extension member may be positioned over the surface using a robotic operator. The extension member may be configured to maintain a selected distance between the applicator and a fluid source for the viscous fluid. The viscous fluid may be dispensed from the fluid source to the applicator. The viscous fluid may be applied onto the surface using the applicator.

An apparatus is disclosed for applying a strip of sealant to a web of roofing shingle stock as the web moves along a processing path. The apparatus includes an applicator wheel disposed on one side of the processing path and having a peripheral surface. The applicator wheel is rotatably mounted and oriented such that rotation of the applicator wheel moves the peripheral surface of the applicator wheel toward, adjacent to, and then away from the moving web of shingle stock. A nozzle preferably in the form of a slot die is disposed adjacent to the peripheral surface of the applicator wheel. A source of sealant is supplied and a delivery system is configured to deliver the sealant from the source of the sealant to the slot die under a predetermined pressure. The slot die and delivery system are configured to project a stream of sealant toward and onto the peripheral surface of the applicator wheel at a predetermined speed. This applies a coating of sealant to the peripheral surface of the applicator wheel. The moving web of roofing shingle stock engages the sealant on the peripheral surface of the applicator wheel as the peripheral surface moves adjacent to the web. This, in turn, draws sealant from the peripheral surface of the applicator and onto the web of roofing shingle stock thereby applying the strip of sealant to the web.

The present invention relates to a self-aligning stencil device for producing a multi-color composite image on a target surface. The self-aligning stencil device includes a central panel and a plurality of stencil panels foldably connected to the central panel. The central panel includes a solid region and a cut-out region. The solid region of the central panel includes a front surface and a back surface, and is defined by an outer border of the central panel and an inner border of the central panel. The cut-out region is vacant space that is defined by the inner border of the central panel. Each stencil panel has its own distinct stencil pattern and is foldably connected to a different corresponding portion of the outer border of the central panel, thereby forming a connection fold between each stencil panel and its corresponding portion of the outer border of the central panel. The plurality of stencil panels, when folded at their connection folds upon the central panel, self-align to collectively form a composite image, so that painting each distinct stencil pattern with a different color is effective to yield a multi-color composite image on a region of the surface imposed behind the cut-out region of the central panel. Also disclosed are kits and methods for producing multi-color composite images using the device of the present invention.
