Abstract: An optical stack for sensing a presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response including a first optical property having a second value in response to an excitation signal including the first optical property having a first value different from the second value. The first optical response includes a second optical property sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate the sensor material and includes a third optical property having respective third and fourth values in response to the respective first and second values of the first optical property. The third value is different from the fourth value by at least a factor of 2.

Abstract: A method for controlling the optical properties of a material comprises the steps of (1) applying a dopant to an undoped TMD film by solution dip-coating the TMD, wherein the solution is a dopant solution consisting of one of NADH (nicotinamide adenine dinucleotide) and TCNQ (7,7,8,8-tetracyanoquinodimethane), wherein the doped TMD film exhibits an altered refractive index (n) and extinction coefficient (k) in comparison to the undoped TMD film. The dopant solution is a 0.1M solution of NADH in anhydrous acetonitrile or a 0.1M solution of TCNQ in anhydrous methanol. Rinsing the doped TMD film with a solvent consisting of one of anhydrous acetonitrile and anhydrous methanol to create an undoped TMD film exhibiting a refractive index (n) and extinction coefficient (k) substantially similar to the original undoped TMD film. The TMD is selected from the group consisting of MoS2, MoSe2, WS2, WSe2, and TiS2.

Abstract: An extruded hook fastener strip is created on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll. The second strip is firmly bonded to the fastener strip on that side opposite the formed hooks.

Abstract: Oil is separated from an aqueous mixture by first feeding the oil-water mixture into a separation tank and allowing the mixture to separate by gravity so that the oil rises to the surface, forming a layer above the aqueous phase; then removing the layer of oil from the surface. The lower aqueous phase, typically containing residual oil in emulsified form, is removed through an outlet near the bottom of the tank and transferred to a second tank, forming a pool therein. The water is removed from the second tank by the action of an air-operated pump through a float-controlled ball valve to an external filter for removal of residual oil.

Abstract: This invention describes a hook design for the hook portion of a hook and loop fastener system, and the hook strip made up of a multiplicity of such hooks projecting from a common base. The hook design encompasses a thickened stem portion projecting from the base and connecting to lobes of a crook portion at a neck. The stem portion is substantially thicker than the crook portion and terminates at the neck. The lobes and the stem are tapered whereby the hook can be easily withdrawn from its mold cavity during the molding operation. The hook is characterized by improved engageability and closure performance.

Abstract: A method for making an extruded hook fastener strip on a roll having hook forming cavities in its surface by extruding plastic material into the interface between the forming roll and a second strip carried by a backing roll is provided. The second strip is firmly bonded to the fastener strip on the side opposite the formed hooks.

Abstract: A strip of fastener material adapted for securing to the surface of a foam bun during molding, carries on a first surface an area of outwardly extending fastening elements constituting one half of a touch fastening system. The first surface is arranged to be positioned so that it faces into a trough in a mold wall and this first surface is provided with a pair of elongated flexible sealing lips adjacent the edges of the are. Magnetizable means are also carried by the strip and the fastener strip has portions extending laterally beyond the sealing lips and beyond the edges of the trough in the mold wall. A strip of removable pressure sensitive tape covers the surface of the fastening elements and extends completely between the lips.

Abstract: The present invention is directed to a molded foamed automobile cushion having a deep groove and an upholstery cover secured thereto by a touch fastener having cooperating hook and loop elements carried by the cushion and cover. One element of the touch fastener is molded into a deep groove in the cushion and the other element is secured to the upholstery. The hook elements on both sides of the groove are unidirectional, when assembled, and have their concave surfaces facing in the same direction to permit easy entry of the upholstery into the groove and providing maximum resistance to removal of the upholstery from the groove.

Abstract: Method and apparatus for treating continuously moving staple length textile fibrous materials to uniformly apply a liquid treating composition, such as a dye or other chemical thereto, wherein loose staple fibers are temporarily formulated into a web for continous delivery by gravity down a conveying chute into the nip portion of a pair of applicator rollers containing a treating liquid on their surfaces, and wherein the fiber conveying chute and its discharge end are maintained at preferred angles of inclination and distances from the nip of the two applicator rollers to facilitate continuous delivery of the fibers uniformly through the nip portion of the applicator rollers to improve the application of liquid materials thereto. The fibers are thereafter continuously conveyed for heat treatment in loose random staple length form and under compression through a RF energy confined heating tube.
