  • Publication number: 20060207231
    Abstract: A dirt separation and collection assembly suitable for use in a bagless vacuum cleaner including two dirt separation and collection zones is provided. Dirty air enters the upper portion of a container and enters a first stage dirt separation zone including a disruptor ring extending inwardly from the outer wall to allow coarse dirt particles and fibers to pass through and collect at the base of the outer wall of the device. The spinning air is then drawn through a conical shroud and fed into a second stage conical separator for separating fine dirt particles and collecting them in an inner substantially cylindrical collection chamber. Air exits the conical separator at the opposite cone opening before being drawn to the suction source. Elements may be oriented upwardly or downwardly depending upon the configuration of the housing for receiving the dirt separation and collection assembly.

  • Publication number: 20060042206
    Abstract: A cyclonic separation device for a vacuum cleaner including a cylindrical housing, an inlet tube parallel to the axis of the housing having a vortex vane disposed axially in the inlet tube. Air rotates in one direction in the inlet tube, and preferably in the opposite direction in the housing. The housing includes a cylindrical sidewall with an upper central outlet tube and a closed bottom for collecting separated dirt. A disrupter ring located on the inside wall of the middle portion of the housing includes a curved surface and sharp edge for lifting air flow off the housing wall. An outlet tube disc spaced from the inlet of the outlet tube is located in the housing below the disrupter ring.

  • Patent number: 5671326
    Abstract: Many machines, particularly computers, execute decision processes during their operation. Such decision processes generally involve ascertaining the values of a number of condition factors and then determining the desired outcome in accordance with a predetermined decision function. This decision function may take the form of a number of individual statements relating condition-factor value combinations to particular outcomes. To facilitate end-user generation and modification of a decision function by generation and modification of a set of component statements, a structured representation for the component statements is presented to the user and statements are created and modified within this structured environment. Before a new or modified set of statements is accepted, it is checked for consistency between statements.
