  • Patent number: 6562015
    Abstract: A disposable absorbent garment includes a backsheet, a liner sheet and an absorbent core disposed therebetween. The backsheet and liner sheets are shaped to form a pair of spaced-apart leg openings with a front waist area, a rear waist and a central crotch area. A pair of ribbons are disposed in opposing curved contours along at least the front and rear areas of the garment and optionally extend through the crotch area of the garment to form a generally oval-shaped exudate containment region about the crotch area of the garment. Each ribbon is fastened to the garment along one longitudinal ribbon edge to form free ribbon edges which rise from the garment to provide a raised barrier.

  • Patent number: 6401944
    Abstract: A corrugated deck for use as decking or shelving in storage racks is provided. The deck has a plurality of apertures punched or formed into the horizontal surface areas according to a predetermined pattern. Each aperture is punched or formed such that a downwardly sloping, vertical flange is created from the surrounding material. The flange directs the flow of liquid into the aperture from the adjacent horizontal surface areas and reinforces the structural integrity of the deck. A storage rack made with decks of this invention meets fire code requirements regarding the percentage of open area in the shelving and at the same time handles high load-bearing applications.

  • Patent number: 6391013
    Abstract: An absorbent article having a main body which includes a backsheet formed of a liquid impermeable sheet, a topsheet formed of a liquid permeable sheet, an absorbent core interposed between the backsheet and the topsheet, and leg gathers disposed along leg holes. Two sets of elastic members are, in a stretched state, bonded to a non-woven fabric along the leg holes. Each set of elastic members is not bonded to the non-woven fabric in a region which traverses a crotch region to extend from one of the leg holes to the other, and is cut in the non-bonded region so that the elastic members snap back toward crossing points where the two sets of the elastic members meet to form tails.

  • Patent number: 6339743
    Abstract: An ignition system for energizing an ignition coil of an internal combustion engine. The system including a high voltage unit for energizing the ignition coil of the engine, a memory for storing system function indices and a processor. The processor receives a timing signal from an engine speed pick-up device, accesses the memory to retrieve the system function indices, and causes the high voltage unit to energize the ignition coil based on the system function indices and the frequency of the timing signal. The system also includes a programmer in communication with the processor for allowing a user to instruct the processor to select and modify the system function indices during engine operation.
