Abstract: A filter cartridge includes a top end cap and a bottom end cap spaced apart from one another. A filter media is disposed between the top and bottom end caps. An outlet channel is within the filter media and extends between the top end cap and the bottom end cap. The outlet channel includes an open top end proximate the top end cap and a closed bottom end proximate the bottom end cap.

Abstract: There is provided a system and method for quick identification and selection of torch processes based on a profile scheme. In an illustrated embodiment, a profile selectable via a one-click process may define operational parameters for one or more torch processes. Multiple profiles may be identified by corresponding labels that are visible on the face of the system. Furthermore, in an illustrated embodiment, the profiles and associated torch processes may be automatically stored in the system upon user configuration of the operational parameters. For example, in one embodiment, the user may select a profile and configure a welding process. Upon changing an operational parameter, it may be automatically saved to the selected profile and process. Reselection of that profile may recall the last used process and its associated parameters. The operational parameters of other configured processes may then be retrieved by selecting the desired process within the selected profile.

Abstract: A passive cooling unit for integrated electronics in form of flat-plate heat-pipe device having a shallow cavity base member, a cover plate, and a lanced-offset fin member and associated porous metal wick material sandwiched therebetween, the fin member being braced to the base member and cover plate to provide structural support and also being coated with the wick material. The resultant flat-plate heat-pipe device, when formed of a lightweight metal such as aluminum or titanium, results in a passive cooling device that is lightweight, structurally strong, and of low cost manufacture.

Abstract: An air moving device in the form of an axial flow fan is provided that is adapted for use in substantially enclosed high-density electrical systems, e.g. computers and the like. The fan includes an annular wall extending about the blades thereof and in which pressure equalizing openings are formed for increasing the maximum pressure in the preferred operating area of the fan and just before the stall effect occurs due to increasing system pressure resistance. A method is also provided for optimizing the number and size of the slots to obtain a desired maximum pressure increase. The slots are optimized so that there is no appreciable airflow loss in early stages of the preferred operating area while providing the desired increase in maximum pressure. The slots preferably have an elongated shape, e.g. rectangular or oval, with a major dimension extending generally axially and parallel to the axis of rotation of the blades, and are spaced from each other circumferentially about the annular wall.
