Abstract: A flexible container in the form of a bag is described for use in a non-immersion dry cleaning process. Bag walls that are appropriately stiff and slick are preferred (preferred Kawabata Evaluation System stiffness and surface friction values are given), as are bag designs that are inherently three-dimensional and self-supporting. A preferred embodiment is a tetrahedral bag having a slick polymeric coating on the interior surface.

Abstract: A woven fabric substrate is treated with a fluorochemical stain resist agent and thereafter extrusion coated substantially on the back side with a layer of thermoplastic polymeric material so as to yield a final construction which exhibits both fluid and stain resistant properties. The fabric substrate can also be treated with an flame retardant agent, an antistatic agent, and/or an anti-microbial agent.

Abstract: An improved fabric for use in applications such as furniture upholstery is provided which possesses desirable flexibility, cleanability, and fluid resistant properties. The fabric includes a textile substrate treated with a fluorochemical stain resist agent. The treated textile substrate is covered substantially on the back with a layer of extrusion coated thermoplastic polymer which is pressed at least partially into the fabric substrate. A process for forming the fluid shield fabric according to the present invention is also provided. Preferably, the fabric is comprised of solution dyed nylon and the polymeric material is ethylene methyl acrylate polymer.

Abstract: An improved pharmaceutical containment package is provided. The containment package includes a blister card disposed between a cover and a backing. At least one of the cover or the backing is a composite structure including a surface layer, a reinforcing fabric substrate layer in underlying relation to the surface layer and a layer of polymeric adhesive disposed between the surface layer and the reinforcing fabric substrate.

Abstract: A method of testing a laser target designator, in which an aperture in the field of view of the laser target designator has one side facing the target image detector and the laser, a beam image detector faces an opposite side of the aperture and is aligned with the opening thereof so that the beam optical axis and the opposite side of the aperture are in a field of view of the beam image detector, both sides of the aperture being illuminated, and beam video processor obtains a test video image from the beam image detector and computes a centroid of the aperture in the test video image and a centroid of the laser beam in the test video image, the displacement of these centroids being a measure of the static error while relative movement of them during dithering of the optical path from the laser target designator is a measure of the dynamic error.

Abstract: A device for automatically compensating for dynamic boresight errors between a visual line of sight and the apparent center of a beam of radiation emitted by the device. The radiation emitted by the device is used to guide a "beam-riding" missile to its target. Different sectors of the beam radiated by the device are modulated by different codes so that the missile can sense the apparent center of the beam. Optics within the device sense the extent to which the visual line of sight deviates from the apparent center of the radiated beam by means of measurements upon the coincidence of the visual line of sight and the apparent center of the beam of radiation within the device. The device then alters the coding of the radiated beam so that the apparent center of the radiated beam maintains alignment with the visual line of sight.

Abstract: A polyester-containing fabric is calendered, using unheated calender rolls and at pressures between about 1,000 p.s.i. and about 3,500 p.s.i., for the purpose of improving the drapeability characteristics of such fabric.

Abstract: A process is provided for the pattern dyeing of textile materials wherein dye migration may be controlled by the in-situ formation of a water-insoluble polymeric skin around individual dye droplets when the dye solution is applied to the textile material. The skin is formed by the ionic interaction of an anionic, water-soluble, organic component with a cationic, water-soluble, organic component. Either or both of the components may be a polymeric material.

Abstract: A fluid sensing apparatus to measure the flow rate of a non-Newtonian fluid by sensing the fluid pressure of the fluid to generate a signal to control a valve. The apparatus includes a fluid receiving chamber which has an outlet tube having a pre-determined flow rate independent of the viscosity of the fluid.

Abstract: Apparatus for the application of liquids to moving material, such as patterned application of dyes to moving textile material, including a liquid applicator positioned above the material path of travel for continuously discharging liquid in a row of plural streams downwardly onto the material, means for selectively deflecting selected of the continuously flowing streams in accordance with a pattern control device, and collection means for receiving the deflected liquid to prevent its contact with the moving material. The apparatus includes a novel flow controller to measure the flow rate of the plural streams from a dye manifold and in response thereto to adjust the flow of dye liquid from the manifold, by opening and closing a valve located in the return conduit from the dye manifold to the dye supply tank.

Abstract: A method and apparatus is described for boresighting the sighting systems ed with a 1.06 micrometer designator laser. The method enables boresighting visual direct view optics, TV, and forward looking infrared (FLIR) sights with respect to the laser itself, without the use of external targets. The laser beam is focused onto a refractory target in the boresight device, creating very briefly an incandescent hot spot which can be "seen" by all three sensors. The radiation from this hot spot is collimated by the boresight device optics and projected back into the sights exactly anti-parallel to the laser beam. By aligning the sight reticles with this hot spot, all three types of sights are aligned relative to the laser. Since the hot flash created by the laser energy is of such short duration, the alignment can be accomplished in flight where relative motion exists between the laser designator system and the boresight module. The apparatus disclosed includes a CO.sub.
