Abstract: A vacuum cleaner having a base with a: nozzle opening, rear housing attached to the base, dirt separator with inlet and outlet passages, vacuum fan, accessory hose, and valve system to connect the separator alternately to the nozzle opening and hose. The valve system has a valve body having a first inlet connected to the nozzle opening and a second inlet connected to the hose, a hose connector that pivots with respect to the valve body, a connector passage through the hose connector, and a flexible outlet hose having a first end connected to the connector passage and a second end connected to the separator inlet passage. The valve inlets are generally equidistant from the connector pivot and the hose connector is pivotable to rotate the first hose end relative to the second hose end to selectively place the connector passage in communication with the first and second valve inlets.

Abstract: A vacuum cleaner housing member having a rigid frame, a grate and a flexible cover. The rigid frame has an outer perimeter and an opening therethrough. The grate is mounted in the opening and has an inner surface, an outer surface, one or more air passages extending from the inner surface to the outer surface, and an outer perimeter wall defining the peripheral edge of the grate. The flexible cover extends over at least one of the one or more air passages and is positioned over at least a portion of the outer surface, extends around at least a portion of the outer perimeter wall, and is positioned over at least a portion of the inner surface. A vacuum cleaner including the housing members similar to the foregoing member is also provided.

Abstract: The present invention relates generally to electrical insulation barriers. More particularly, the invention encompasses an electrical insulation barrier having knock-out features for an electronic apparatus. The electrical insulation barrier is preferably made from a brittle material, such as, for example, a thermoset insulating material, a glass reinforced polyester laminate material (such as, for example, GPO-1, GPO-2, GPO-3), and the like. The electrical insulation barrier is preferably used to insulate and/or isolate electrical conductors. With this invention a single master or universal type part can be made and used in many configurations and locations dependent on the design of the electronic apparatus. The invention allows for the creation of one or more opening in the electrical insulation barrier by knocking-out or removing one or more pre-defined shapes to allow clearance for intersecting electrical parts.

Abstract: A low pressure, high temperature composite bridge plug. The bridge plug comprises a mandrel with a plurality of slips disposed therearound. A wedge is initially attached to said mandrel and in planar contact with the slips for forcing the slips radially outwardly into gripping engagement with a wellbore. An elastomeric sealing element is disposed on the mandrel and compressed between the wedge and a shoulder on the mandrel to expand the packing element radially outward into sealing engagement with the wellbore. A plurality of ratchets retained in a ratchet body grippingly engage the mandrel to prevent the plug from unsetting. The mandrel, slips, wedge and ratchet body are preferably made of non-metallic, composite materials for easy drilling.
