Abstract: A cooling system configured to cool an interior of an enclosure includes a cabinet, and a vortex tube secured within the cabinet. The cabinet defines a venting chamber. The vortex tube includes a hot pipe within the venting chamber, and a cool gas delivery pipe extending outwardly from the cabinet. The cool gas delivery pipe is configured to deliver cold gas to the interior of the enclosure. A dampening sleeve may be secured around at least a portion of the hot pipe, such that the dampening sleeve dampens noise produced by the vortex tube. Additionally, at least one dampening sheet may line at least a portion of the interior and exterior surfaces of the cabinet.

Abstract: A flow amplifying pump apparatus includes a body member that defines a flow passageway and a compressed air inlet. The body member includes a main segment and an insert segment which extends into a container and rotates relative to the main segment. A cover member which lies releasably secured to the body member supports a plug assembly. The plug assembly includes a plunger that defines a groove for cooperating with a protuberance in the cover member to guide the plunger along a predetermined, substantially linear path.
