Abstract: A gutter assembly includes a gutter that may be attached to an eave of a roof thereby facilitating the gutter to capture a fluid from the roof. The gutter has a bottom side and the bottom side is positionable in an open position. Thus, the bottom side releases debris from the gutter thereby facilitating the gutter to be cleaned of the debris. A cord is attached to the bottom side such that the cord may be urged downwardly thereby positioning the bottom side in the open position.

Abstract: A disposal bag for disposal of sanitary products adapted for use with a bin of a sanitary disposal unit is provided. The bag comprises an inner surface, an outer surface and an edge providing an opening into the bag. The bag includes a frame having at least a pair of spaced-apart sidewalls having foldable portions positioned thereon which permit the frame to fold together. The frame is configured to be positioned adjacent an upper edge of a bin. The edge of the bag is coupled to the frame. The frame is configured to hold the bag in an opened position such that the bag and frame cooperate to prevent sanitary products from falling between the bag and a sidewall of the bin. When the frame is removed from the bin when the bag is filled, the frame is configured to fold together to seal to itself to provide a closure for the bag.

Abstract: A system for disposal of refuse adapted for use within a waste disposal unit is disclosed. The system includes a frame and a plurality of bags, nested within each other and within an outermost bag, where the bags are attached to the frame and are held open for the disposal of refuse thereinto. A disposal bag assembly for disposal of refuse is also disclosed.

Abstract: A system for disposal of sanitary products adapted for use with a sanitary disposal unit, is provided. The system includes a plurality of bags. Each bag has an inner surface, an outer surface and an edge providing an opening into the bag. The system also includes a bag frame which includes an upper perimeter and at least one leg. The bag frame is configured to be positioned in a holding area of a sanitary disposal unit. The bag frame is configured to hold a plurality of bags while holding the edge of one of the plurality of bags coupled to the upper perimeter of the frame. The frame is configured to hold the one bag in an opened position such that the one bag and frame cooperate to prevent sanitary products from falling between the bag and a sidewall of the sanitary disposal unit. When the one bag is removed from frame when the bag is filled, the one bag is configured to fold together to seal to itself to provide a closure.

Abstract: A system for disposal of refuse is disclosed. The system includes a support and a plurality of bags associated with the support such that a first bag is held open to receive refuse and another bag is readily available to replace the first bag when the first bag is filled and removed. The support of the system is configured to be folded into a flat configuration.

Abstract: A stack of interleaved towels is provided wherein each towel is configured from a sheet of material having a first fold to generate a first panel, a second fold in the sheet substantially parallel to the first fold and creating a second panel, and a third fold substantially parallel to the first and second folds and creating a lead flap and a trailing flap. The lead flap is defined between the first fold and the third fold such that the first fold presents a leading edge for grasping by a user. The trailing flap is defined between the second fold and the third fold. Prior to interfolding, the first panel is positioned directly adjacent the second panel. Additionally, the trailing flap of each sheet of material is disposed between the lead flap and the trailing flap of an adjacent sheet of material such that the sheets of material are interleaved.

Abstract: A multi-headed ink-jet system adapted to eject encapsulated liquids is provided, which includes a plurality of concentric piezoelectric members. Each concentric piezoelectric member has a chamber configured to carry a liquid therethrough, and each concentric piezoelectric member is in liquid communication with an exit port provided in a concentric orifice. When each concentric piezoelectric member is actuated, a liquid contained in its chamber is moved near or through the concentric orifice. The plurality of concentric piezoelectric members cooperate to control the ejection of liquids through the concentric orifice to permit one liquid to be encapsulated by another liquid to form an encapsulated droplet. A method of operating a multi-headed ink-jet system adapted to eject encapsulated liquids.

Abstract: A system and method for cooling blood is described. One embodiment includes a tube configured to be inserted into a blood vessel; a blood-conveyance pathway located inside the tube; a blood inlet configured to allow blood to enter the blood-conveyance pathway from the blood vessel; a blood outlet configured to allow blood to move from the blood-conveyance pathway into the blood vessel; a coolant-supply pathway located inside the tube and adjacent to the blood-conveyance pathway; a coolant-return pathway located inside the tube; and a coolant-turn-around connecting the coolant-supply pathway and the coolant-return pathway.

Abstract: A system and method for high throughput patch clamp measurements to study the effect of various chemicals on ion transfer channels is provided. One or more patch clamp configurations is established, each comprising a cell sealed to a pipette. The pipettes are affixed to a pipette fixture. The pipette fixture and a plate comprising one or more wells are relatively moved so that each cell is inside a well. Electrical properties of the cells are measured.
