Abstract: A pump for processing molten metal having an enlarged tubular body which houses a centrifugal pump at its bottom end. The bottom end has a parabolic shape which receives the ejected molten metal from the impeller and forms a vortex within the tubular body. The pump is controlled to cause the vortex to climb up the inner wall of the body up to and out of an outlet formed in the upper end of the body. A radial vane impeller is formed in the back plate of the impeller. When the impeller is rotated, solid particles introduced into the body are accelerated radially by the back plate impeller into the vortex.

Abstract: A biodegradable tag having a leaf-shaped body portion and an inwardly spiraling attachment appendage. The tag including at least one seed that is disposed within a seed compartment formed in the body portion. The body portion is formed from a liquid-absorbing material that absorbs a scented animal attractant liquid.

Abstract: A centrifugal pump having a turbine impeller having a plurality of curved vanes. The vanes curve from the inlet end to the outlet end in the direction of pumping rotation of the impeller, such that the leading wall of each vane re-directs a portion of the radial velocity of the fluid flowing through the passage to increase the total tangential velocity provided by the impeller. Each vane includes a cavity which entrains fluid which slides back from a spinward passage and redirects the entrained fluid back in the direction of rotation.

Abstract: The present invention is a deep frying apparatus for cooking food items within a deep stock pot. The apparatus includes a pot-shaped basket and a plurality of stackable cooking racks with flat screen bodies and spaced handles which project vertically from the screens and which concomitantly provide a loop for handling each rack and for spacing apart adjacent stacked racks. A bottom-most cooking rack further includes feet which raises the bottom-most rack's screen above a bottom wall of the basket when inserted therein.

Abstract: A high-torque electric motor having a rotor supported by an elongated torque arm comprising a pair of frustoconical-shaped support members. The rotor has a spherical-shaped outer surface and a complementarily shaped stator cavity. The spherical magnetic elements and the conical support members cooperate to brace the rotor against deflection along its rotational axis.

Abstract: A torque converter having an internal lock-up clutch which is activated by the elastic expansion or ballooning of the torque converter housing. This ballooning occurs due to the increased internal fluid pressure within the torque converter.

Abstract: An paint roller assembly having a paint roller and an elongated extension pole. The paint roller is coupled to the extension pole by a pivoting head that is selectively lockable at various user-selected angles. The pivoting head and paint roller include complementary seat and recess sections that always position the roller either parallel or perpendicular to the pivot head's axis of rotation.

Abstract: The present invention provides for an improved bathroom fixture for flushing bodily waste materials. This fixture includes a secondary drain that communicates liquid that is backing up during a potential overflow situation into a conventional drainage sewer without any modification to that sewer.

Abstract: A cutting tool having a cutting portion located proximate to one end. The cutting tool including a recessed chip flute formed along the shank of the tool away from the cutting edge. The tool includes a chamfering cartridge which is clamped to the tool shank along the chip flute. The chamfering cartridge performs a chamfering or deburring operation while allowing chips from the cutting portion to pass through the flute and away from the tool and workpiece.

Abstract: A wall structure for either a building or a stand alone wall is formed with stacked horizontal elongated panels. The upper and lower faces of each panel interlocks with its neighboring panel with a tongue and groove joint to form a continuous wall surface.

Abstract: A furnace filtration system for improving the speed and efficiency of a molten metal centrifugal impeller pump contained within a non-ferrous molten metal furnace. The system includes a filtration well located upstream of the pump well. The filtration well includes a filter having a plurality of through filter passages that are sized to prevent any solid contaminants that are larger than the pump's impeller openings from passing therethrough. By preventing any contaminants that cannot pass through the pump, the pump can be run at a higher speed. A furnaces efficiency increases with the centrifugal pump's efficiency increases with its centrifugal pump's speed along with the flow and pressure.

Abstract: A cap in combination with spectacles that are removably coupled to the underside of the cap's visor. The spectacles are pivotally movable from a first deployed position, where the lenses are disposed in front of a user's face to a second stowed position, where the spectacles underlie the visor. The pivoting mechanism is axially biased to provide constant pressure to hold the spectacles in substantially any position.

Abstract: A method for reducing the coefficient of friction of an archery arrow's shaft to ease the retrieval of the arrow from an archery target. The method includes covering the shaft between the ferrule and fletching with a PTFE-based lubricating material, buffing the lubricant to a uniform thickness along the arrow shaft and heating the lubricated shaft to set the PTFE to the arrow shaft.

Abstract: The present invention provides a right angle track clip installation tool. The tool includes a pair of handles that are pivotally coupled together and a pair of crimping blocks that are coupled to the handles through ball joints. These ball joints cause the crimping blocks to project from the handles in a generally perpendicular direction. This handle/crimping block arrangement permits a user to install snowmobile track clips to a track without removing the track from the snowmobile.

Abstract: A furnace flow control valve for use within a bath of molten metal. The flow control valve includes a vertically-disposed elongated tubular stator, which is configured to receive flow from a molten metal pump. The valve has a rotor which is sealing rotatable within the stator between: a full re-circulation position, where flow from the pump passes un-hindered through the valve; a full transfer position, where flow from the pump is redirected into the vertically disposed stator and out of the valve; and a partial re-circulation/partial transfer position where flow from the pump both passes through the valve and is transferred up and out of valve through the stator.
