  • Publication number: 20180165997
    Abstract: A hollow body with attractive movement effects. The transparent hollow body is filled with a viscous transparent liquid (F). This body contains two types of small-part bodies used as floating bodies (S) and even smaller-sized bodies as drive bodies (K). The floating bodies (S) have an arbitrary average diameter and the drive elements (K) preferably have a significantly smaller diameter than the floating bodies (S). The density of the material of the floating bodies (S) is always less than that of the material of the drive bodies (K). The hollow body contains two perforated plate plates (3) spaced apart from one another, provided as horizontal intermediate walls, so that the hollow body forms a central sub-chamber as well as an upper and a lower sub-chamber (2) for the plurality of floating and drive bodies (S; K).

  • Publication number: 20050002177
    Abstract: This invention relates to a fantasy lamp comprising a narrow, transparent hollow chamber (15) which receives at least two immiscible liquids and the back of which can be illuminated, wherein the hollow chamber comprises wall sections (13, 14) disposed at a slight distance from each other. The hollow chamber can be rotated about a substantially horizontal axis (10) when the wall sections are aligned substantially vertically. At least one of the liquids is coloured. An electric motor drive (4), which is mounted in a chassis (1), is provided for rotating the hollow chamber (9). The hollow chamber (15) forms a component of a cover (9), and the drive (4) cooperates with a radially outer region (18) of the cover (9). When the hollow chamber is slowly rotated about the substantially horizontal axis, particular aesthetic effects can be achieved due to the liquids by means of a fantasy lamp which is fashioned in this manner.

  • Patent number: 4085533
    Abstract: The specification describes a device for producing aesthetic effects, more particularly light effects, with at least one partly transparent or transluscent and preferably closed vessel. The vessel contains at least two liquids of different density which are not completely and not permanently miscible with each other. In the order of increasing density at least three liquids A, B, C with the following principal or sole components are employed:A liquid paraffin and/or silicone oil and/or naphthene and/or hexachlorobutadiene;B water or an ether, more particularly propanetrioxyethylether or a polyether;C esters with chemically bound phosphorus and/or chemically bound halogen, preferably chlorine, an ester of phthalic acid, and more particularly dibutoxybutyl phthalate, a carbonic acid ester, more particularly propanediol carbonate, or ethanediolmonophenylether or tetrahydrothiophene-1,1-dioxide with the provision that the selected liquids are not completely and not permanently miscible with each other.
