  • Publication number: 20020047295
    Abstract: A programmable seat back damper assembly for a motor vehicle includes a generally horizontal seat cushion portion and a generally upright back portion operatively connected to the seat cushion portion. The programmable seat back damper assembly includes a recliner for operative connection to the seat back portion and the seat cushion portion. The programmable seat back damper assembly also includes a damper for operative connection to the seat back portion and the seat cushion portion and having a magneto-rheological (MR) fluid therein. The programmable seat back damper assembly further includes a controller electrically connected to the damper to control an apparent viscosity of the MR fluid to increase and decrease damping of the damper for adjusting an angle of the seat back portion relative to the seat cushion portion.

  • Patent number: 6300301
    Abstract: A cleansing preparation is provided in the form of an oil-in-water emulsion. The oil phase particles have a median particle diameter by volume of not more than 1 &mgr;m, and a preservative is present in at least the aqueous phase. A method is described of making this preparation, in which a coarse emulsion is formed, the coarse emulsion is homogenized, and the homogenized emulsion is diluted by an aqueous dilution liquid containing the preservative. Cleansing articles, for example baby wipes can be made in which a substrate carries the cleansing preparation.

  • Patent number: 5698306
    Abstract: The present invention provides a microwave silicate foam susceptor which comprises a dry sodium silicate foam substrate coated with an effective amount of microwave active material. The silicate is preferably a sodium silicate, but can be other suitable alkali metal silicate, and the active constituent is preferably graphite, but other actives can be used. The susceptor of the present invention is capable of quickly reaching and more importantly maintaining extremely high temperatures. This enables it to brown and crispen foods in a microwave oven.
