  • Patent number: 11155405
    Abstract: A waste disposal apparatus, such as a waste disposal container or unit that is configured to receive used personal care products in a discreet and sanitary manner. Instances of incontinence, menstruation or uncontrollable bodily functions can be a personal situation that is otherwise unknown to others. However, current receptacles available to dispose of used personal care products fail to provide for a hygienic, easily accessible and discreet that is designed for small spaces, such as a home bathroom or public restroom stall.

  • Patent number: 8293948
    Abstract: A reagent for organic synthesis with which a chemical reaction can be conducted in a liquid phase and unnecessary compound(s) can be easily separated at low cost from the liquid phase after completion of the reaction. The reagent for organic synthesis reversibly changes from a liquid-phase state to a solid-phase state with changes in solution composition and/or solution temperature, and is for use in organic synthesis reactions. This reagent for organic syntheses facilitates process development. With the reagent, research on and development of, e.g., medicines through, e.g., compound library synthesis, etc. can be accelerated. It can hence contribute to technical innovations in the biochemical industry and chemical industry.

  • Patent number: 6583182
    Abstract: This invention involves synthesis and use of a class of compounds with chelation affinity and selectivity for first transition series elements. Administration of the free or conjugated compound, or physiological salts of the free or conjugated compound, results in decrease in the in vivo bioavailability of first transition series elements and/or removal from the body of first transition series elements and elements with similar chemical properties. These characteristics make such compounds useful in the management of diseases associated with a bodily excess of first transition series elements and elements with similar chemical properties. This invention demonstrates that such compounds inhibit mammalian, bacterial, and fungal cell replication and are therefore useful in the treatment of neoplasia, infection, inflammation, immune reponse, and in termination of pregnancy.

  • Patent number: 5476964
    Abstract: Benzyl alcohols having a chiral center at the benzylic carbon can be conveniently racemized by treatment with solid acids which are strongly acidic cation exchange materials. Racemization may be effected generally in the range from 20.degree.-150.degree. C. in aqueous or partly aqueous systems in combination with a water-miscible organic solvent to improve solubility of the alcohol. Similar racemizations may be effected for benzyl ethers and esters. This process is valuable for recycling of unwanted enantiomers obtained in the resolution of racemic mixtures.

  • Patent number: 5374365
    Abstract: A polyphenol compound wherein the aromatic rings are linked by direct bonds or by a divalent link in the ortho position relative to the --OH group and the end aromatic rings contain either oximino substituents or substituted alkylaminomethyl substituents in the ortho position. The compound can be coated onto a metal surface to give improved corrosion resistance. The metal surface can be zinc-coated steel or zinc phosphated steel. The polyphenol compound can be the only coating material or can be incorporated into a surface coating composition such as a paint.

  • Patent number: 5338469
    Abstract: A combination of Mannich type reaction products of ethoxylated alkylated phenol, and alkylated arylamine possess excellent antioxidant properties. The presence of alkylated phenol in the structure is believed to provide a synergistic antioxidant activity with the aromatic amine. Presence of the alkylated aromatic moiety is believed to provide enhanced lubricant solubility compared to unalkylated diphenylamine type antioxidants. Application of these synergistic mixtures of additives and synthetic base stocks in premium automotive and industrial lubricants will significantly enhance stability and extend service life.
