  • Publication number: 20040119747
    Abstract: An improvement to the known method/system for distribution of elements displayed in GUI windows and similar processing environments is disclosed. A visible, moveable, and size-adjustable bounding box is provided. The user can specify any size for the bounding box and locate the bounding box anywhere in the window. In this manner, the user adjusts the size and location of the bounding box as desired, rather than having to manipulate the various elements to try to define the desired spacing and location.

  • Publication number: 20030214143
    Abstract: The invention describes a system for locking and unlocking containers truck chassis, railroad cars, airplane cargo decks, each other when loaded onto ships or in container yards and to other bases. The invention uses the energy exerted by lifting devices including lifting spreaders and fork lifts to create tension on a connecting line which rotates a locking leg housed in the lower corner fitting of a container to unlock the container from a base beneath it. The invention is comprised of a plate and spring housed in an upper corner fitting of a container, a line connected to the plate and guiding eyes to route a line from the plate to a locking leg housed in a lower corner fitting of a container. When the twist lock of a lifting spreader mates with the upper corner fitting of a container it forces the plate and spring in the upper corner fitting downward.

  • Patent number: 6634169
    Abstract: A catalyst system includes a three-way catalyst (TWC) mounted underfloor and an engine management system programmed to initiate an enrichment of the exhaust gases exiting the engine with at least one of CO and hydrocarbons and to add secondary air to the exhaust gases in the exhaust passage upstream of the TWC. This periodic enrichment and addition of secondary air causes catalytic oxidation of the at least one of CO and hydrocarbons over the TWC thereby raising the underfloor TWC temperature to at least 550° C., preferably higher, in order to reduce sulphur poisoning of the catalyst and maintain the desired catalytic activity.

  • Patent number: 6479023
    Abstract: A system for converting particulate matter in exhaust gases, which system comprises a stoichiometrically-operated engine and an exhaust system including a plasma generator for converting water vapor in the exhaust gases into an oxidant and a filter downstream of the plasma generator. A method for converting particulate matter (PM) in exhaust gases by using plasma-treated water vapor as an oxidant to convert PM trapped on a filter disposed in an exhaust system, and/or to oxidize NO and/or N2 to NO2, in which water vapor, PM, NO and N2 are present in the exhaust gases of a stoichiometrically-operated gasoline engine. The NO2 is then used to combust the PM. Experimentally, the conversion of a gaseous hydrocarbon using a plasma with and without water vapor present can be followed using mass spectrometry.

  • Patent number: 6260287
    Abstract: A sheet stabilizer is provided for a dryer section of a paper-making machine which conveys a wet sheet of paper by way of a felt or fabric, the dryer roller including a leading upper dryer roller, a lower dryer roller, and a trailing upper dryer roller. The sheet stabilizer comprises upper and lower Venturi boxes, which are disposed between the leading upper dryer roller and the lower drying roller. Each Venturi box provides a respective space defined by fixed parallel outer and inner plates. In use, the wet sheet of paper is in sliding contact with the upper outer plate. The upper and lower Venturi boxes cooperate to draw air from the nip between the wet sheet of paper and the lower dryer roller and into both the upper fixed space and the lower fixed space. The sliding contact between the supported wet sheet of paper and the upper outer plate assures that the air flow does not result in fluttering of the wet sheet of paper.

  • Patent number: 6255288
    Abstract: The invention relates to the use of methanebisphosphonic acid derivatives of formula I for the treatment of fractures. These compounds have surprisingly been found to promote a more rapid and stronger fracture healing in mammals including man.

  • Patent number: 5270078
    Abstract: A method for preparing high resolution wash-off images, preferably using ink jet printing, comprising the sequential steps of: (a) providing a non-photosensitive layer, preferably on a substrate, wherein the non-photosensitive layer comprises a polymer selected from the group consisting of acid containing polymers having at least 0.4 milliequivalents of acid functions per gram of polymer and amine containing polymers having at least 0.4 milliequivalents of amine functions per gram of polymer, (b) applying an aqueous ink imagewise to the non-photosensitive layer to form a salt of the polymer in the ink applied areas, said aqueous ink comprising an aqueous carrier medium and a salt-forming agent; and (c) washing the non-photosensitive layer with an aqueous solution to remove the imaged areas of the non-photosensitive layer.

  • Patent number: 4894898
    Abstract: A method of producing castellated beam. A first continuous cut 18 is made along the web of a universal beam, and a second cut 20 is then made along the web on a path differing from the path of the first cut. The cuts are such as to define rectilinear sections (24, 26) lying on alternate sides of the centerline of the web and at least partly curvilinear sections (25, 27) joining the closest ends of adjacent rectilinear sections. The cut halves of the beam are separated and are then welded together (at 28) in regions formed by juxtaposition of rectilinear sections of the two halves. Beams, having circular, elliptical or other curvilinear openings can thus be made.

  • Patent number: 4561661
    Abstract: The soccer training device for head and foot consists of three major parts, i.e. a base support structure, a fiberglass rod, and a ball. The base support structure is designed similarly to parasol stands; however, it possesses a mechanism for continuous height adjustment of the ball and the fiberglass rod. To this mechanism the rod is attached by means of a swing element.At the tip of the fiberglass rod, the ball is attached to a revolving bearing. The fiberglass rod can have inclinations of approximately 0.degree. to 30.degree.. The fiberglass rod and the swing element serve the purpose of storing potential energy for the return flight of the ball.The ball is set into motion by the head or the foot of a player, and swings back and forth in an arc section of circular radius.
