The invention relates to a method for preparing a relief printing plate from a printing plate precursor wherein at least an end of the precursor is attached to a leader forming a composite printing form precursor that securely mounts the precursor in a treatment processor. The present method advantageously allows for all or substantially all of the area of the precursor to be utilized for forming the relief surface suitable for printing.

Composite printing form precursor and method for preparing a printing form precursor for treatment

A method and apparatus of securing and tensioning a printing form in an apparatus having a rotatable drum, comprising positioning a first portion of the printing form over a first set of pins that are coupled to a surface of the drum. The first portion of the printing form is then stamped onto the first set of pins thereby securing the first portion of the printing form to the drum. A rotatable member having a second set of pins is rotated so that the circumferential distance between the first set of pins and the second set of pins, is about equal to the length of the printing form. The drum is rotated until a second portion of the printing form is positioned above the second set of pins. The second portion of the printing form is then stamped onto the second set of pins.

The invention concerns a method of forming a fabric of interlaced yarn by arranging on a surface a plurality of yarn guide blocks, each guide block adapted to guide yarn from a yarn source to the surface and wherein the relative motion of the yarn guide blocks and surface serves to deposit yarn from the guides onto the surface in such a way that when said yarns are deposited on a surface, the diagonal positions of the yarns from one block are offset from a direct overlapping alignment with the yarns from the remaining blocks to thereby densely cover the surface during repeated cycles of such motion.

Rapid fabric forming

The invention comprises a flat or shaped fabric structure of yarn groups each yarn group comprising a plurality of yarn subgroups, each group positioned for covering an area. The structure comprises at least a first group of flexible yarns densely covering an area , the yarns within the first group following substantially parallel paths in a first direction and forming a stack with at least a second group of flexible yarns densely covering substantially the same area, the yarns within the second group following substantially parallel paths in a second direction; the yarns in the first group arranged to cross the yarns in the second group, optionally containing other groups of yarn, the yarns in the upper-most subgroup of the stack are connected to the yarns in the bottom-most subgroup of the stack either directly of through the yarns in other subgroups providing an interlaced fabric structure.

This invention provides moisture stable tuftstring carpet assemblies. The pile surface structure comprises a moisture stable backing substrate, a plurality of elongated pile articles each comprising an elongated, moisture stable support strand having bonded thereto a plurality of 'U' shaped bundles of multifilament yarn. The pile articles are bonded to the backing substrate. Different backing substrates and support strands may be used.

Moisture stable tuftstring carpet

An elongated pile article having a support strand for attachment to a plurality of yarn bundles, the yarn bundles including a dense portion with the filaments bonded to each other and bonded to the support strand, pile surface structure comprised of a plurality of elongated pile articles placed one next to the other, and a method and apparatus for making the elongated pile article.

A hood suitable for protection against decompression and toxic fumes having a flanged neck seal.

Protective hood with elastomeric neck seal

A hood suitable for protection against decompression and toxic fumes, prepared using a laminar structure of polyimide, two or more layers of fluoropolymer and heat sealable polymer that affords the heat resistance of polyimide with a markedly lower internal noise level, ease of fabrication and resistance to etching by flame. An improved neck seal is also provided.
