Abstract: A method for mounting a slider device on a recloseable package includes mounting the slider device by intersecting the slider device with a zipper arrangement so that at least one of the slider device and the zipper arrangement is distorted to allow mounting. A particular method includes mounting the slider device includes intersecting the slider device with the zipper arrangement at an angle between about 20 to 60.degree., preferably about 45.degree.. In another method, the zipper arrangement is distorted to facilitate mounting of the slider device thereon, and in yet another method, the slider device is distorted to facilitate mounting.

Abstract: Naturally occurring bauxites are suitable as flame retardants and can be incorporated into polymeric carpet backings, when they are ground or pulverized to obtain a generally uniform distribution of particles predominantly less than 250 micrometers in size and containing up to 45 wt. % of fines (less than 3 micrometers in size), and then used in combination with an appropriate wetting agent, dispersant, froth aid, latex, and thickener package to wet-out and disperse the particles and provide adequate control of viscosity build. The bauxite should preferably have a high gibbsite content and should preferably have a pH range of from 4.5 to 8. Mechanical stirring can be used to aid in viscosity control. Lowering the specified percent solids in a formulation by adding small amounts of water allows for even finer ground bauxite (up to 55 wt. % of fines) to be used as filler for carpet backings.

Abstract: An apparatus for manufacturing containers or bags includes a sealer that produces seals on a moving film. These seals are spaced at intervals that determine the length of the containers. An operator can change the desired container length while the film is moving. In response to such changes, a control arrangement adjusts the speed at which the sealer rotates and, in turn, the spacing of the seals and the length of the containers.

Abstract: A peelable seal includes four layers. The first layer includes first and second alternating ribs. The first ribs comprise a first material, and the second ribs comprise a second material. The first material bonds well with the closure profiles. The second material bonds well with the third and fourth layers. The first material does not bond well with the second material. Thus, the bond strength is lower between the first and second ribs and between the third and fourth ribs than between the first and third ribs and the closure profiles and between the second and fourth ribs and the third and fourth layers. In this process, the strength of the peelable seal is controlled during the extrusion process rather than being subjected to the variations in the manufacturing process. Alternatively, the peelable seal includes six layers. The first and second layers bond well with the closure profiles. The third and fourth layers bond well with the fifth and sixth layers.

Abstract: A heat insulating layer exists between the attachment layer and the closure profile 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 beat insulating layer insulates the profile layer from the heat load to prevent distorting or melting of the profile layer. The heat insulating layer also supports the profile members perpendicular to their respective base strips to facilitate opening and closing of the resealable package.

Abstract: A lenticular preprinting process producing a composite image which, when printed, is assembled with a lenticular lens material (18). The composite image is developed from a plurality of images (A-D) which include both graphic and textual images. Each of the respective images are digitized and a pixel array for the image is formed. Separate digital files are created for each image. Next, computerized files are separately created for continuous tone images and for linework images. From these computerized files, separate raster image files for the continuous tone and linework images are produced. Next, segments from each raster image file is combined in a predetermined sequence with segments from the other raster image files to separately interlace the respective continuous tone and line work images. The resulting combined files are now linked to produce an image having both continuous tone and linework constituents.

Abstract: A light-weight, corrosion-resistant, readily installed bridge deck is formed of modular deck panels spliced to each other on site. Each of the deck panels is shop-fabricated by longitudinally welding flanges of adjacently placed multi-void extruded aluminum alloy structural elements. Transfer splices of longitudinally adjacent elongate elements are made by providing shear elements connecting individual elongate structural elements of each deck panel end-to-end prior to longitudinal welding of adjacent elongate elements, with the end joints between the elongate elements being arrayed in a staggered manner. A safety rail system is mounted to run alongside and above outer edges of the finished bridge deck mounted to a system of support girders.

Abstract: Closure arrangements for use with flexible packages include a zipper-type closure, which, after initial sealing, if access is gained to a package interior, the arrangements provide evidence of that access. In certain embodiments, a closure with mating male and female profiles is used which, after initial sealing of the package, if access is desired to the package interior, one of the male or female profiles breaks, to prevent a resealing of the package. In other embodiments, after initial mating of the male and female closure profiles in order to seal the package, if access is desired to the package interior, the package walls are torn in order to gain access. In other embodiments, after initial sealing of the package by mating of the male and female profiles, if access is desired to the package interior, the male and female profiles are deformed, such that they no longer mate to provide a secure closure. Methods for using the arrangements herein are also provided.

Abstract: The resealable package includes a first panel section sealed to a second panel section along two side edges and a bottom edge. The sealed edges define an enclosed region having a mouth that provides access to the enclosed region. The package also includes a closure arrangement for opening and sealing the mouth. The closure arrangement is oriented in the mouth and secured to the first and second panel sections. The closure arrangement and a seal along one of the side edges define a gap having a first area. The closure arrangement includes two closure profiles. Each closure profile has a base strip and an interlocking closure member extending from the base strip. The two closure profiles are designed to selectively interlock. The interlocking closure member of the first closure profile is designed to reduce the area of the gap between the closure arrangement and the side seal.
