Abstract: A vacuum cleaner with a cooled drive belt is described. The vacuum has a handle, body, base housing, cooling fan, motor, drive belt and a drive belt housing. A fan draws ambient air over a drive belt within the belt housing. The belt housing can have a main belt housing and a belt housing cover. The belt housing can contain an air intake and air exhaust connected by an air duct. Belt housing can have a filter in order to clean intake air. The result is a vacuum with significantly greater longevity—reducing costs and increasing reliability of the vacuum for the user.

Abstract: A vacuum cleaner base having a volute air outlet and a beater bar housing that are substantially collinear is described. In some embodiments, the beater bar housing includes an air outlet, the volute includes a volute air inlet disposed parallel to the beater bar housing, and a volute air outlet disposed orthogonal to the beater bar housing, and an air duct connecting the volute air inlet and the air outlet of the beater bar housing; wherein the air outlet of the beater bar housing and the volute air outlet are substantially collinear. Additionally a vacuum cleaner comprising a unibody mount bracket is described. In some embodiments, the unibody mount bracket includes one or more handle receptacles, a dirty air outlet configured to receive a dirty air conduit, and a pivot joint disposed adjacent the dirty air outlet, wherein the pivot joint is configured to receive a bag mounting member.

Abstract: A separation assembly is generally described that can chemically treat condensate material in a fluid stream. One particular example of a separation assembly is a crankcase filtration assembly used in engine oil filtration and that includes an additive material disposed within the crankcase filtration assembly. The additive material chemically treats condensate material of blow-by fluids received by the crankcase filtration assembly when a condition is present in the condensate material. For example, the crankcase filtration assembly provides a unique structure with a chemically treated component that can reduce an acidic condition in condensate material received by the crankcase filtration assembly, and even more generally may extend engine oil life.

Abstract: A cord management system operable to reduce or eliminate various forces exerted on a vacuum cleaner power cord. The system includes a swiveling strain relief incorporated into the vacuum handle and collars, used to connect sections of a dirty air conduit, having exterior portions that enable the power cord to be retained in a secure manner.

Abstract: A print service supports print by reference operations. Software hosted or accessible by a web site performs the required functions. A print client may be a print device, for example, that has an Internet connection. A print client might also be a portable wireless device, for example, which then might transfer data transcoded by the print service to a print device. The print service accepts a reference to print content, resolves the reference, obtains the print content, transcodes the print content into a print device ready format, and allows the print client access to the transcoded print data. The print service method realized by such a web site provides commercial potential for web services and content provider partnerships, as a preferred use of the print service might commence with a user of a portable wireless device obtaining a reference to print content while web surfing, communicating that content.

Abstract: A power shaft including a belt retaining geometry is provided according to an embodiment of the invention. The power shaft includes a shaft including a normal belt position portion adapted for receiving a belt and a reduced diameter portion formed on the shaft and located adjacent to the normal belt position portion. The belt can move into the reduced diameter portion of the power shaft during operation and the reduced diameter portion creates an alignment tension force on the belt that operates to return the belt to the normal belt position portion.
