  • Publication number: 20050163649
    Abstract: A candle with a fragrance or scent reservoir comprising a wax candle incorporating a single or multiple reservoirs containing scented oil(s), scented wax stick(s), scented wax bead(s), or scented granules. The reservoir or reservoirs are formed in the candle body generally along one or more wicks. The reservoirs may also be formed in a wickless candle typically known as a tart or a melt candle. The scent is a perfume that can either be liquid, gel or solid. As the candle wick(s) burns and creates a melt pool, the fragrance materials mix with the melt pool and release the fragrances. A method of displaying and selling the candles uses a display cabinet with multiple shelves for displaying the various candles of various sizes, colors and shapes, and displaying different fragrance materials.

  • Patent number: 5308604
    Abstract: The invention relates to conjugates composed ofa) at least one polyalcohol or a derivatized polyalcohol,b) at least one active agent,c) at least one linker andd) a protein,wherein the polyalcohol(s) or the derivatized polyalcohol(s) are polyalcohols or derivatized polyalcohols which are not recognized by the defense system of an organism as exogenous, and the protein is a protein which can be taken up by the tumor specifically or non-specifically, and is not recognized by the defense system of an organism as exogenous. These conjugates are suitable for, on the one hand, making possible a very sensitive method in nuclear medicine for the diagnosis of tumors and, on the other hand, for example also offering new methods for diagnosing tumors in X-ray diagnosis, computerized tomography, nuclear spin tomography, electron spin resonance spectroscopy or electron microscopy.
