A paint applicator, kit and methodology for using the same is disclosed. For example, a paint applicator that allows a user to load a desired amount of paint, such as a water based or other low VOC paint, into the paint applicator and an advancement mechanism that dispenses paint at a rate controllable by the user is disclosed. The advancement mechanism can include a system that translates a rotational force applied to an end cap of the applicator into a linear force that advances a piston which in turn applies paint to an applicator portion. The paint applicator may be reusable or may include a ratchet system that allows for only one time use. The methodology and kit can incorporate a syringe for loading paint into the paint applicator, thus reducing the loss of paint through spilling.

A writing and underline-drawing implement includes: an elongate hollow body having an open top portion and a closed bottom portion; an elongate core received in the elongate hollow body, the elongate core having the tip portion; a cap having a tip hole partially formed in a top portion thereof, the cap being hollow and having an open bottom portion to partially receive and/or passed through by the elongate core, the cap being configured to at least partially move along a length of the elongate hollow body; and rotatable guide wheels coupled to the cap at an upper portion of the cap, the cap being disposed between the guide wheels.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

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.

The principles and embodiments of the present invention relate generally to systems and methods for applying a catalytic coating to the outwardly facing edges of the cell walls of a catalytic substrate to reduce the amount of soot that accumulates at the entrances of the substrate cells that can increase back pressure and reduce the flow of exhaust gases through the substrate.

A glue application roller for use in a gluing assembly equipped with at least one scooping roller includes a glue roller body that is provided with a central hole to receive a drive shaft. The glue roller body has at least two parts including a base and an outer ring. The base is operatively connected to the drive shaft by a non-positive fit. The outer ring is configured with at least one cavity. The base and the outer ring are coupled to each other non-positively via at least one first means. On at least one side of the glue roller body, there are second means that ensure that compressed air and/or another gaseous or liquid medium is fed into or discharged from the cavity so as to effectuate a change in a circumferential contour of the cavity.
