Abstract: A blowing nozzle having a substantially parabolic blowing end is provided which entrains ambient gases into the output flow. A plurality of outlets are arranged so as reduce turbulence within the flow. The substantially parabolic blowing end converges at an apex coaxial with a blowing axis. A central outlet is provided at the apex to generate a core stream of gas. First outlets surround the central outlet. Second outlets surround the first outlets and are angled inward toward the blowing axis. Fins and/or additional outlets may be provided.
Abstract: A method, device, and nozzle for dispensing cooled lubricant is provided. Lubricant is supplied to the nozzle through an inner lubricant tube. Cooled compressed gas is also supplied to the nozzle through a conduit which surrounds the inner lubricant tube. Cooled compressed gas from the conduit is introduced into a nozzle gas bore in the nozzle and lubricant is introduced into a nozzle lubricant bore in the nozzle. The cooled compressed gas and the lubricant are mixed at a junction between these bores, such that the lubricant is siphoned into the junction by the cooled compressed gas. The mixture of cooled compressed gas and lubricant are then dispensed from an aperture in the nozzle, preferably as a fine atomized mist of cooled lubricant.

Abstract: An apparatus for cooling an enclosure provided. The enclosure has at least one opening for receiving cool air and discharging heated air. The apparatus includes a vortex tube with a first end for discharging warm air and a second end for discharging cool air. The apparatus further includes an inlet between the ends of the vortex tube for directing compressed air tangentially into the interior of the vortex tube. A first housing covers the first end of the vortex tube and creates a space through which warm air is channelled to the exterior. The vortex tube is connected by an attachment to the opening of the enclosure so that the vortex tube can discharge cool air into the interior of the enclosure. The apparatus further includes an air outlet conduit at an end of the attachment to facilitate discharge of heated air for the enclosure.
