  • Patent number: 7000520
    Abstract: A slide cutter assembly for use in sectioning lengths of a packaging material drawn from a roll. The device includes an elongated and shaped body. A first roll supporting portion is located at a first end of said body and a second roll supporting portion is likewise located at a second end of the body. A cutter assembly extends from a selected lengthwise extending edge of the body and upon which an unwound length of the packaging material comes into contact. The cutter assembly incorporates a traversable blade for sectioning from the roll the length of packaging material. The roll of packaging typically comes in a generally elongated and three-dimensional shaped packaging, the cutter device being constructed so that it may be supported within an interior defined by the packaging and upon first mounting the roll between the first and second roll supporting portions.

  • Patent number: 6902639
    Abstract: A solvent-based adhesive is used to form a continuous, adhesively bonded and welded seam at the longitudinal edge portions of plastic film which have been overlapped. First, a bead of the adhesive is disposed on the edge portion of a web of film passing over an applicator roll. Next, as the film moves between the applicator roll and nip rolls, the adhesive dissolves a portion of the film to form a longitudinal channel having a generally semicircular cross-section. Then the edge portion is overlapped onto the other edge portion with the bead of adhesive between them. Finally the overlapped edge portions are squeezed between the nip rolls, so that the adhesive exudes laterally outward from the groove and is distributed smoothly between the overlapped edge portions, until the adhesive and dissolved film form a uniform band having a rounded hat-shaped cross-sectional profile.

  • Patent number: 6697171
    Abstract: A process for adjusting the content of a digitized image file used in printing an interlaced image on a lenticular lens material to substantially eliminate ghosting effects which might otherwise occur when the printed image is viewed by an observer. A pixel address within the image file is selected, as is a preselected number of pixel addresses adjacent the selected address on both sides thereof. Percent color values contained at each of the addresses within the resulting range of addresses are added together and the result divided by the total number of addresses to compute an average color percent value. The percent color value at the selected address is compared with the computed average and is changed by a predetermined amount if the percent color value is greater or less than the computed average. The revised percent color value is then stored at the selected address. The process is repeated for each pixel address within the file.

  • Patent number: 6656295
    Abstract: A free machining aluminum alloy contains an effective amount of one or more high melting point constituents that provide enhanced machining capability. The high melting point constituents occupy from about 0.1 to about 3.0 volume percent of the aluminum alloy. The constituents can be any material that is essentially insoluble in the aluminum alloy matrix so as to form a discontinuity and one that will resist deformation during machining to enhance the formation of voids between the matrix and the free machining constituents. The constituents include elements, nitrides, oxides, borides, carbides, silicides, aluminides and combinations thereof that have a high melting point and high strength and low solubility in aluminum at the elevated temperature so that the constituents resist deformation during the machining operation. The free machining aluminum alloy can be formed as a workpiece and subjected to any machining operation.

  • Patent number: 6656296
    Abstract: An aluminum alloy article containing the alloying amounts of iron, silicon, manganese, titanium, and zinc has controlled levels of iron and manganese to produce an alloy article that combines excellent corrosion resistant with good formability. The alloy article composition employs a controlled ratio of manganese to iron and controlled total amounts of iron and manganese to form intermetallic compounds in the final alloy article. The electrolytic potential of the intermetallic compounds match the aluminum matrix of the article to minimize corrosion. The levels of iron and manganese are controlled so that the intermetallic compounds are present in a volume fraction that allows the alloy article to be easily formed. The aluminum alloy composition is especially adapted for extrusion processes, and tubing that are used in heat exchanger applications.

  • Patent number: 6623693
    Abstract: An aluminum alloy composition consists essentially of controlled amounts of iron, silicon, copper, manganese, magnesium, titanium, zinc, zirconium, and free machining elements with the balance being aluminum and incidental impurities. The alloy provides improvements in combined strength, corrosion resistance, machinability, and brazeability. A component or article made from the aluminum alloy can be machined to the right configuration and can be brazed to another component to form a high quality brazed joint. In addition, the article can withstand corrosive environments and has the necessary mechanical properties to interface with other components. The alloy is adapted for particular use as a component in a heat exchanger assembly, such as a connector block having one or more machined surfaces or passageways.

  • Patent number: 6423164
    Abstract: A method of producing aluminum alloy sheet product includes casting a slab or ingot, homogenizing the cast slab, and hot rolling the homogenized slab to provide an intermediate gauge product. The temperature and other operating parameters of the hot rolling process are controlled so that the temperature of the ingot at the beginning of hot rolling is maintained at a temperature between 925° F. (496° C.) and 1025° F. (552° C.), and the temperature of the intermediate gauge product exiting the hot rolling step is between about 500° F. (260° C.) and 600° F. (316° C.). The intermediate gauge product is then subjected to a cold reduction of 45% to 70%, annealed, and cold rolled to final gauge.

  • Patent number: 6409966
    Abstract: One free machining aluminum alloy includes bismuth as a free machining elemental constituent that functions as a discontinuity in the aluminum alloy matrix rather than a low melting point compound. Using bismuth in weight percents of the total composition ranging between 0.1% and 3.0% improves both machinability and mechanical properties. The bismuth can act as a substitute for another free machining constituent in a free machining aluminum alloy or can be added to an aluminum alloy to improve its machinability. Another free machining aluminum alloy has bismuth and tin as free machining constituents for improved machining. When using bismuth and tin, the bismuth ranges between 0.1 and 3.0% by weight and the tin ranges between 0.1 and 1.5% by weight.

  • Patent number: 6361211
    Abstract: A heat insulating filler is mixed into the attachment layer of a resealable closure mechanism for a package. A heat and pressure sealing process is used to attach the closure profile to a resealable package. A heat-sealing bar is used to apply a heat load into the attachment layer causing the attachment layer to fuse with the film of the package. The heat insulating filler insulates the profile layer from the heat load to prevent distorting or melting of the profile layer. The heat insulating filler also supports the profile members perpendicular to their respective base strips to facilitate opening and closing of the resealable package.

  • Patent number: 6322647
    Abstract: Methods of improving the corrosion resistance and hot working productivity of AA7000 series aluminum alloys include, in one mode, the steps of treating a stock material to form a globular microstructure, preferably by a thermal conversion treatment, and subsequently hot working the treated stock material, quenching it and aging it. The globular microstructure permits increasing the hot working rate to attain T6 properties using only a T5 temper practice and without adverse effect on the surface of the hot worked product as a result of the increased hot working rate. Consequently, an acceptable product is made at a significantly lower cost due to the increased hot working rates and fewer processing steps. The method also improves the corrosion resistance, particularly exfoliation corrosion resistance, of the product such that corrosion resistance generally attainable using only a T7 temper practice is achieved using only a T5 temper practice.
