Abstract: A perpendicular axis saw blade includes a blade body with an outer blade body edge to which a plurality of primary saw teeth are affixed at spaced intervals to form a primary teeth per inch (TPI). The blade also includes a plurality of primary gullets. Each primary gullet is located between two of the plurality of primary teeth and has a primary gullet depth and primary gullet capacity. Each of the plurality of the primary teeth includes a primary tooth tip, a primary tooth leading edge, a primary tooth trailing edge. Secondary saw teeth affixed at spaced intervals to the primary tooth trailing edge or at least one primary gullet form a secondary TPI. The primary teeth cut a workpiece during a machining operation. A user or system can use the secondary teeth to cut through a foreign object detected in the workpiece without damaging any primary teeth.

Abstract: A full power portable vacuum cleaner having a charging base which may provide vacuuming function similar to a household dustpan may employ a concealed hose and a retractable cord. To meet various cleaning demands, the vacuum cleaner may operate with different function modes, including the dustpan mode (vacuum through a port at the bottom of the vacuum body) for planar surface vacuuming, and the cordless portable mode for on-spot vacuuming. The vacuum cleaner may further employ multiple power supplies, including an internal battery supply, wall power supply, or car power supply.

Abstract: A gas/liquid separator (1) assembly is provided. The assembly generally comprises a vessel with at least one internally received serviceable separator element (10) arrangement. A unique inlet baffle arrangement (36,39) is provided, to facilitate preseparation of liquid from gases, as gases are passed through the assembly. The assembly is particularly adapted for use in air/oil separation, for example for compressors. Methods of assembly and use are also described.

Abstract: A serviceable gas/liquid separator is provided. The gas/liquid separator has a cross-section with one long axis and one short axis, with an aspect ratio of at least 1.3. A preferred cross-section, is an elliptical cross-section. Assemblies in which the separator unit can be used, are provided. In addition methods of use and construction are provided.

Abstract: A gas/liquid (e.g., air/oil) separator assembly. The assembly has a vessel having a top plate, a separator element within the vessel, an aperture in the top plate for receiving the separator element therethrough, and a lid fitted to seal with the top plate and cover the separator element in the vessel. The lid may be configured for threaded attachment to the top plate. Methods of use and servicing are also provided.

Abstract: A liquid reservoir tank assembly includes a gas-liquid separator, such as an air-oil separator. A tank body has an open end, a portion of the tank body forming a liquid separation chamber, another portion of the tank body forming a liquid reservoir. A tank cover covers the open end of the tank body, the tank body and the tank cover providing a gas inlet and a gas outlet with a gas flow through the separation chamber from the gas inlet to the gas outlet. The gas-liquid separator is mounted in the separation chamber in the gas flow between the gas inlet and the gas outlet. The separator has a coalescing stage layer and a drain stage layer arranged radially symmetrically about an axis extending through the interior of the separator, the coalescing stage layer being upstream of the drain stage layer. Each of the layers is generally frustoconical in shape.
