Abstract: A non-flip mattress with top side and bottom side and depending edges; wherein the bottom side is covered with a flame-resistant, highly needled, double-sided-calendered, needlepunch nonwoven fabric that passes 16 CFR 1633. The nonwoven fabric is a double-calendered, 80/20 flame-resistant rayon/polyester blend needled with a minimum of 190 punches per cm2 and with increased tensile strength.

Abstract: An automatic testing illumination system has advantages of speed, quick calibration ability and therefore high accuracy over conventional illuminators. An spherical light source/concentrator exit port is rapidly and sequentially covered by at least one automated device for affecting the light leaving the exit port. Automation enables a very rapid sequencing of light onto a two or three dimensional array to cut the time for test and evaluation, and to permit very accurate calibration of the illuminator system.

Abstract: Boresighting apparatus includes a laser, a thermal target having an absorbent surface for receiving the laser beam and converting it to a heat spot of infrared radiation, and an optical device for receiving and optically displaying the heat spot. The thermal target is anisotropic, having a low thermal conductivity in the direction laterally of the surface and a high thermal conductivity in the direction perpendicular to the surface, so as to increase the duration of the heat spot with a minimum lateral spreading.

Abstract: A fabric forming device including a stationary yarn supply and a rotating yarn supply, each delivering yarn to a common point along a vertical axis where they are interlaced. The stationary yarn supply includes a plurality of yarn carrying cones which are arranged along a common horizontal plane about the vertical axis. The rotating yarn supply includes a plurality of yarn spools mounted with a rotating plate about the vertical axis. A plurality of vertically moveable guide members which are adapted to engage with the yarns of the rotating yarn supply act to selectively alter the horizontal path along which the yarns travel. The guide members act to control the yarns of the rotating yarn supply to be selectively positioned to pass above or below the cones carrying the stationary yarns so that the yarns interlace in a desired manner.
