Contact surface having a composite release layer and method of making

Publication number: US10161082B1

Application number: 15/201,492

A processing roll has a release layer that includes a porous rigid layer and polymer composite. The porous rigid layer may be a thermally sprayed metal that has discrete metal portions or a network of contiguous metal portions. Discrete metal from a flame sprayer may attached to each other on a contact surface to form the rigid layer. The polymer composite at least partially fills the spaces between the metal portions. The polymer composite may comprise a particulate filler, such as silica or glass beads. The release layer has good durability as the exposed surface contains both a portion that is the rigid material and a portion that is the polymer composite. This configuration enables very high release and long term durability even as the release layer wears.

Personal cooling device

Publication number: 10,006,651

Application number: 15/835,759

A personal cooling device utilizes a portable container for retaining a liquid that is wicked into a wicking, material and a fan to draw air into the container through a plurality of apertures to produce a flow of cool air. Air drawn into the container through the apertures flows through the wicking material and is cooled by evaporative cooling. The air then flows out of the top of the container and through the air moving device. A funnel is configured around the outer perimeter of the container to capture any liquid that spills out of the apertures and direct it back into the container. A battery pack may be coupled to the air moving device by an extension cable for storing the battery pack in a more convenient location, such as on a belt.

Enclosure temperature control system

Publication number: 9,999,179

Application number: 15/211,398

An enclosure temperature control system utilizes a renewable power source and a thermal sink to reduce the overall power requirements from a power grid. A renewable power source, such as a solar panel may provide power that drives the components required to maintain the greenhouse temperature within upper and lower limits, including a HVAC system and/or a heat transfer system coupled with a thermal sink. The thermal sink includes a phase change material that releases heat when it solidifies and this heat can be used to heat the greenhouse. Likewise, the phase change material absorbs heat during the day to reduce the temperature within the greenhouse. A heat transfer system may be coupled with the phase change material and a solid conductor component within the tank of a phase change material may increase thermal transfer rate.
