Abstract: Disclosed herein are devices and methods for controlled delivery of a treatment gas to treat a raw agricultural product, for example by contacting the raw agricultural product with the treatment gas. The devices and methods can deliver a dose of the treatment gas at a relative velocity, wherein the dose of the treatment gas and the relative velocity are selected in view of the surface reactivity of the raw agricultural product to be treated.

Abstract: Disclosed herein are systems and methods for treating air.

Abstract: Various implementations include a fluid treatment device. The device includes an outer tube, an inner tube, a plurality of blades, and a media. The outer tube includes an inner surface. The inner tube is coaxially disposed within the outer tube. An outer surface of the inner tube and the inner surface of the outer tube define an annulus that axially extends between the ends of the inner tube. The plurality of blades is disposed within the annulus. The plurality of blades is configured to alter a component of a flow direction of fluid flowing over the blades in a circumferential direction and/or a radial direction. The media is disposed within the inner tube. The inner tube defines a plurality of perforations extending between its outer surface and inner surface. The annulus defines an entire flow path of fluid flowing between the outer tube and the inner tube.

Abstract: A fishing tackle component has a portion useable to receive a noise making mechanism, which can be a depression. The noise making mechanism is a rattle mechanism, including a capsule containing at least two rattle elements. The rattle elements may have a minimum curvature that is greater than a maximum curvature of the capsule, allowing the rattle elements to move freely inside the capsule. Consequently, the capsule does not have acute angles or areas of extreme curvature in which the rattle elements can lodge disabling the noise. The rattle mechanism is mounted to the receiving portion, such as in the depression. As the lure is moved through the water, the rattle mechanism at least sporadically produces a noise regardless of the speed or trajectory of the tackle component in the water.
