Abstract: A molten metal flow controller (10) for a metal melt furnace having a tap hole (T) to release the molten metal from the furnace, where the controller (10) is configured to controllably release the flow of molten metal through the tap hole (T) using an actuator (14) that controllably moves a plunger (110) into and out of the tap hole (T) in response the increase or decrease in the molten metal flow rate through the tap hole (t) as measured by a sensor (130).

Abstract: A connector for pipe or tubing. The connector includes a unitary expansion member, formed from a body, a first expansion leg extending from the body, an optional second expansion leg extending from the body, and at least one opening extending through the body. In use, the connector is fastened in place by a fastener that is inserted through the at least one opening to contact at least one of the first and second expansion legs and force at least one of them to deform and contact the inside of the pipe or tubing, thereby securing the connector within the pipe or tubing.

Abstract: A rail system includes a cap rail defining a slot. Within the slot may be positioned expansion brackets that permit the cap rail to be mounted to a wall or a post. The expansion bracket is configured to engage an end of a fixture to position and secure the fixture within the slot. The expansion bracket defines a cable way for wires extending to or from the fixture. Other expansion brackets may be mounted within the slot to position and secure ends of fixtures when the mounting expansion brackets are not correctly positioned with respect to the end of the fixture. A rail system includes a pair of rails extending between a pair of posts. An in-fill panel is positioned within slots of each rail and extends between the rails. Expansion brackets within the slots engage the panel.

Abstract: A general-purpose reusable algebraic-based composition algorithm for composing mappings between data schemas. The algorithm handles more expressive mappings, makes a best-effort to eliminate symbols when a perfect answer cannot be obtained, includes new heuristics, and is extensible. A relational algebraic language is provided wherein each mapping is expressed as a set of constraints, and each constraint is either a containment or equality of two or more relational algebraic expressions. The composition mechanism exploits monotonicity properties of algebraic operators in operator arguments, handles NULLs and bag semantics, operates to allow composition to produce a partial result when a complete result is not possible, facilitates symbols elimination one symbol at a time using left composition, for example, as a way of isolating the symbols, supports making a best-effort to eliminate as many symbols as possible from an intermediate schema, and handles unknown or partially known operators via delayed handling.

Abstract: An applicator for a liquid product includes an elongated base having a product cup sized for retaining a single-dose quantity of a liquid product; an applicator cup for receiving an applicator pad; and a channel interconnecting the product cup and the applicator cup. An absorbent applicator pad is disposed in the applicator cup. A liquid product is positively retained in the product cup until it is desired to apply the liquid product.

Abstract: A box has a plurality of outer panels forming an outer enclosure, and a plurality of inner panels. At least some of the inner panels are disposed in a reinforcing relationship adjacent corresponding ones of the outer panels to resist crushing of the box. The box may include a lid moveable between an open position and a closed position, and which is retained in the closed position by a pattern of perforations. A blank for the box is a sheet-like member having a plurality of panels separated by a plurality of fold lines. The blank is adapted to be folded to define the outer enclosure and inner panels of the box.

Abstract: A system that facilitates composition of schema mappings. A general algorithm is provided for composing a broad class of mappings, where one or both mappings are not functions, such as constraints between two schemas and the inverse of functions. A composition component performs composition on schema mappings of disparate data sources, which schema mappings can be expressed by at least one of full, embedded, and second-order dependencies, wherein the second-order dependencies need not be in source-to-target form. The algorithm for composition further includes a procedure that tests whether the composition algorithm will terminate.

Abstract: The present invention is a kit for use by a person to apply a daily treatment of medication and therapy to remove a corn or callus from the person's skin while providing maximum comfort to the person and minimal damage to healthy skin. In one embodiment, the kit comprises a box, an AM treatment system, and a PM treatment system for application at night. The AM treatment system comprises a plurality of AM foam bandages each having a medicated foam pad of hydrocolloid. The PM treatment system comprises a plurality of PM foam protective covers and a plurality of PM medicated non-woven patches impregnated with salicylic acid. The PM treatment system allows the person to remove a single PM medicated patch, trim it to fit the shape of the corn, and position it as desired over the corn. The person may then remove a single PM foam protective cover and apply it over the PM medicated patch, covering it completely, thereby limiting migration of the salicylic acid to healthy skin.

Abstract: A metering valve includes a valve stem co-axially slidable within a chamber body. The chamber body and the valve stem define a metering chamber. An outer and an inner annular seal is provided operative between a respective outer end and an inner end of the chamber body and the valve stem to seal the annular metering chamber there between. The inner seal comprises a wiper element.

Abstract: The desktop organizer includes a main tray for adhesively mounting to a top rear surface of the computer keyboard and a set of removable compartments for detachably mounting to a rear edge of the main tray. Each compartment is provided with a upper forward depending flange for engaging with an upper edge of the main tray. The compartments thus depend from the main tray along a rear surface of the keyboard. The compartments are arrangeable along the length of the main tray in a variety of different configurations. One or more of the compartments is sized for storing computer floppy disks. At least one of the compartments is sufficiently short such that, when positioned along the rear surface of the keyboard, it does not interfere with a keyboard cord extending outward from the rear of the keyboard. The provision of detachable and reconfigurable compartments allows the desktop organizer to be configured to avoid interference with access to disk drives of the computer.
