Abstract: A high performance, laminating, coverlay, and bond ply adhesive material includes one or more epoxy components which inter-react with a high molecular weight polyester component through a two-stage reaction sequence. The first stage of the reaction sequence includes a reaction between a aziridine cure component and a polyester component. The second stage of the sequence involves a reaction between the aziridine/polyester component and the epoxy component(s). The resulting adhesive material provides a flexible, fully cross linked adhesive material with good Z-axis stability and without the evolution of volatile by-products. This resulting adhesive material can be used in bonding polyimide films to etched circuit patterns to provide a high temperature resistant, solvent resistant, moisture resistant, insulating material with good flow properties under normal electronic circuit processing and environmental conditions.

Abstract: A dust-resistant mirrored surface reflector for use with a source of artificial light is provided. The reflector comprises (i) a planar transparent substrate (such as a sheet of glass or plastic), (ii) a reflective metal layer coated onto one side of the substrate, and (iii) a transparent, conductive material layer (such as indium oxide, tin oxide, zinc oxide or indium-tin oxide) coated onto the other side of the substrate. The conductive material layer has an electrical resistance less than about 10.sup.12 ohms per square.

Abstract: An opener device for winding one or more strands of yarn, optionally used with a yarn heat setting apparatus. Strands which have been heat set and then cooled are wound onto a spool by one of a plurality of winding units in the opener device. The opener has a central drive means which moves a plurality of conveyor belts through the opener. These belts induce the rotation of a plurality of cam rollers and each of the cam rollers powers a pair of winding units. The winding units, each of which includes a grooved cam roller for feeding yarn onto a spool, are coupled to the cam roller by an eddy current coupling unit. The eddy current coupling unit imparts the rotation of the cam roller to the grooved cam roller by magnetism. The rotation of the grooved cam roller causes the spool to rotate and wind yarn due to friction. The eddy current coupling unit has two gap/separated drive plates, one with a magnetic layer and the other with a current carrying layer.

Abstract: The present invention relates to a unique radiation curable coating formulation used in the manufacture of window films. The coating composition is a mixture of radiation polymerizable monomers. The mixture includes a triacrylate or a tetraacrylate and acrylic acid. The thickness of the coating after polymerization ranges between about 1 and 2.5 microns. The coating can be applied to metal substrates and is used to achieve a superior abrasion resistant coating having optimum infrared absorption, while using high infrared absorption components in the coating mixture. Typically, the coating is applied to metal, for example, to aluminum substrates used in the fabrication of insulating window film or window structures. A process for applying the coating to such substrates is also disclosed.

Abstract: A process is disclosed for the rapid, continuous and waterless dyeing of textile and plastic materials in which the dyestuff is dissolved, suspended or dispersed in a high boiling solvent, such as glycol or glycol ether, for carrying out the dyeing step per se, after which the dye textile or plastic material (after cooling if desired) is subjected to a washing with a low boiling organic liquid such as methanol or ethanol (preferably the former) or a chlorinated hydrocarbon solvent, and subsequently dried. The entire series of operations is carried out under nonaqueous or substantially nonaqueous conditions with the complete or substantially complete recovery and recycling of the used dyestuff, the used high boiling solvent, and the used low boiling organic wash liquid.

Abstract: The present invention relates to a closed cycle apparatus for the rapid, continuous and waterless dyeing of a textile or plastic material with a dyestuff dissolved or suspended or dispersed in a high boiling solvent (such as glycol or glycol ether or other members of the alcohol family) for carrying out the dyeing step, after which the dyed textile or plastic material subsequent to cooling is washed with a low boiling liquid (such as methanol or ethanol) and then dried. The apparatus is constructed so as to operate under non-aqueous or substantially non-aqueous conditions with the complete or substantially complete recovery and recycling of the used dyestuff, the used high boiling solvent and the used low boiling wash liquid.
