Abstract: A method of displaying a video image in a computer which has the ability to simultaneously display multiple windows. A graphics image is displayed in a first window, and a video image is displayed in a second window having controls for annotating the graphics image in the first window.

Abstract: A cable wrap fabric for protecting a communications cable is woven of fiberglass yarns plied with or without low melt thermoplastic yarns, and water swellable superabsorbent yarns. The water swellable superabsorbent yarns are interspersed at spaced intervals within the fiberglass yarns. The fiberglass yarns dissipate heat energy created by lightning strikes or excessive thermal shocks. The superabsorbent water swellable yarns block the progression of water through the cable. The low melt thermoplastic yarns, if used, fuse the other component yarns of the fabric together so that the fabric can be slit into the required tape widths without excessive yarn fraying at the edges.

Abstract: A video conferencing system, wherein multiple parties at different locations can view, and modify, a common image on their computer displays. The invention also provides a video camera at each computer, which takes a video picture of each party.The invention distributes data to all computers involved in the conference from which each computer can generate a display containing the common image, the modifications, and the video pictures.

Abstract: Smoke containment curtains formed of flexible, smoke impermeable fabric formed of a fiberglass fabric substrate coated with a smoke impervious composition on at least one side. The coating includes a halide-free fire retardant incorporated into a halide-free acrylic or silicone resin. The resulting fabric has an LC.sub.50 of greater than 50 grams.

Abstract: A tunable laser rangefinder having a wavelength tunable transmitter output and a wavelength tunable receiver that matches the transmitter wavelength. The transmitter provides laser energy output pulses that are reflected off a target and received by the receiver. The time between the transmitter pulse and the receiver pulse is determined and the range of the target is calculated. The transmitter and receiver frequencies are changed from pulse to pulse to provide good countermeasure immunity. In a preferred embodiment the rangefinder uses a solid state, reliable cobalt magnesium fluoride laser to provide laser energy in a region of the infrared spectrum which is eye safe and has good atmospheric transmission.

Abstract: A process for manufacturing a coated, smooth, fabric useful as a Navy board facing and the like is described by first applying to at least one face of a glass fiber substrate a uniform layer of a flame-retardant coating containing a pigment, a flame-retardant and a resin contacting and encapsulating substantially all of the yarns of the substrate with a tough, adherent film, then drying the thus-coated substrate. The coated fabric, when exposed to heat or flame, emits vapors of low-toxicity and low-smoke.

Abstract: A process for manufacturing a coated, sculptured, nubby fabric useful as a ceiling board facing and the like comprising:(1) applying to at least one face of a nubby, textured fabric substrate a uniform layer of a thick, flame-retardant, non-cellular coating containing a pigment, a flame-retardant and a resin contacting and encapsulating substantially all of the yarns of the substrate with a tough, adherent film, the coating composition when exposed to heat or flame emitting vapors of low-toxicity and low-smoke, and(2) drying the thus-coated substrate.

Abstract: Method and apparatus for producing textile yarns so that one surface of the yarn exhibits a visually perceptive darker color hue when compared to another surface of the yarn. The yarn surfaces are coated with a colorant-containing liquid (e.g. a dye- or pigment-containing liquid) and are subsequently dried to effect a drying rate differential between the one and another surfaces to cause the colorants to migrate towards the faster-drying surface to a degree sufficient to achieve the darker color hue thereon. Twisting of the produced yarns during packaging and/or weaving will thus create a woven textile fabric having randomly distributed color variations to achieve a visually pleasing striated, tone-on-tone or heather fabric appearance.

Abstract: A three-dimensional printed ceiling board facing material is disclosed in which a greige, foam-coated fabric is selectively printed with an expandable print paste or foamable plastisol. Upon heating, the expandable or foamable coating is substantially increased in size and bonded to the coated substrate. Novel and attractive architectural effects and hand are achieved while the facing meets commercial requirements of light fastness, heat stability and flame resistance. The printed fabric is useful as a ceiling board facing when a highly visible three-dimensional appearance is required.

Abstract: A cellular foam coated fabric suitable for use as a ceiling board facing is produced by sculpturing a layer of vinyl or acrylic foam on at least one side of a nubby textured greige fabric, the foam containing a latex polymer cell producing surfactant, a white powdered pigment, and flame retardants if required. The foam is applied to the fabric in quantities sufficient to cover the face of the fabric, which is then passed through gapped means such as gapped pad rolls. These gapped rolls distribute the foam onto the entire face of the fabric and remove excess foam to provide extra depth and nubbiness to said fabric face without hiding completely the original fabric pattern without crushing the foam or the fabric. The result is a three-dimensional or sculptured fabric with the foam greatly enhancing the loft, texture and nubbiness of the fabric. The coated fabric is useful as a ceiling board facing.
