  • Process for odor control
    Patent number: 5071622
    Abstract: This invention relates to a process for reducing odor perceived by a nearby community from an odor-emitting system, e.g., sewage treatment, etc., by adsorbing on core particles, as described, condensible components present in the system. The malodorous components then cannot adsorb in a film of condensible components on the aerosol to be carried by the aerosol plume into the surrounding community, but remain with the humid gas plume to be dispersed upward into the atmosphere. The process is useful for any system which contains condensible components and malodorous components and whose emissions form aerosols.

  • Polyurethane elastomer tire fill compositions and method of making same
    Patent number: 5070138
    Abstract: A method for making a polyurethane elastomer tire fill composition wherein a mixture of a) a low functionality (2.0-2.3) 4,4'-diphenylmethane diisocyanate, such as a carboiimide-modified (2.0 functionality) 4,4'-diphenylmethane diisocyanate and b) a nonreactive diluent, such as an oil extender, is mixed with a polyol, such as polypropylene oxide triol. The reaction mixture is inserted into a tire casing under pressure and cured therein to form an essentially void-free tire filler. The tire fill composition maintains pressure within the tire during use and has excellent physical and thermal properties. No prepolymer step is necessary in the method.

  • High-speed modulator of the polarization of an optical carrier
    Patent number: 5069520
    Abstract: The modulator comprises an integrated optical switch (6) receiving at an input a linearly-polarized optical carrier and transferring same to a first or a second output (P3, P4), according to the logic values of the bits of a modulating binary data signal. The radiations outgoing from the switch are sent to a polarizing beam splitter (13) with their original polarization or with a polarization rotated by 90.degree. depending on the switch output (P3, P4) from which they come. A signal with the original polarization or with the polarization rotated by 90.degree. is present at the splitter output, depending on the logic values of the bits of the modulating signal.
