    摘要： Stable graft polymer dispersions are prepared employing in situ free radical polymerization of ethylenically unsaturated monomer or monomers in an amine-terminated polyoxyalkylene polyether polymer. These dispersions are useful in the preparation of polyurethane foams which have improved tensile strength, elongation, load deflection and tear strength properties.

    摘要： Slush is made from a liquid using slush making systems or according to slush making processes. A jacketed vessel of the processes and the systems has an interior wall that defines an interior space. The interior space comprises a top and a bottom. The interior space has an average overall cross-sectional area taken through a vertical axis extending generally between the top and the bottom. The interior space also has a collection portion having an average collection portion cross-sectional area taken through the vertical axis that is less than the average overall cross-sectional area. The liquid is placed into the interior space and the interior walls are cooled. Slush forms on the interior walls and migrates to the collection portion. The collection portion is located at the interior space bottom when the slush density is higher than the liquid density and the collection portion is located at the interior space top when slush density is less than the liquid density. To facilitate the migration of the slush to the collection portion, at least a conical portion of the interior space has the general shape of a cone and the collection portion is located in the proximity of an apex of the conical portion, thereby helping to funnel the slush to the collection portion. The cryogenic liquid to be made into slush may be oxygen, nitrogen, hydrogen, helium, or water. The slush may be used to densify cryogenic liquids, such as cryogenic liquid propellants.

    摘要： An optics assembly for observing a panoramic scene. The optics assembly includes a plurality of optical elements. A first element redirects light from the panoramic scene. The optical power of the first element forms an imaginary pupil. The energy from the first element is redirected about 90 degrees, forming an annular path. A second element receives the redirected light and re-images the imaginary pupil to form a real pupil. This portion of the energy continues to be in an annular form. A third element includes an optical relay system having a group of reimaging optics. The third element receives light from the second element while relaying the real pupil into the reimaging optics. It also establishes the focal length of the optics assembly, corrects pupil aberrations produced at the real pupil, corrects field aberrations and produces an annular image on a flat focal plane. The optical relay system interfaces with the second element through the use of the real pupil. The real pupil is formed at the cold stop and filter location in the third element. This pupil is relayed back through the system to be coincident with the first real pupil. The optics assembly produces a small F-number at field angles near perpendicular to the output optical axis of the optics assembly over a panoramic scene.

    摘要： Graft polymer dispersions in a polyol are prepared by a continuous process employing in situ free radical polymerization of an ethylenically unsaturated monomer in a polyol containing from about 0.001 to 0.09 mole of induced unsaturation per mole of polyol in the presence of an effective amount of a chain transfer agent. Products prepared by this process have uniform viscosity with resulting product uniformity. Polyurethane foams incorporating flame retardants prepared from these dispersions readily pass the California No. 117 Flame Test.
