  • Patent number: 7452503
    Abstract: An apparatus useful for disseminating volatile liquid such as fragrance into an atmosphere from an evaporating surface adapted to oscillate in the atmosphere. Oscillation is caused and maintained by means of two magnets, one a permanent magnet, the other an electromagnet, one of which is attached to the evaporating surface. The electromagnet is caused to repel the permanent magnet at such points in the oscillation that the oscillation is maintained.

  • Patent number: 7252805
    Abstract: A device which uses a heat source for heating and diffusing fragrant oils or insecticidal oils. The oil is contained in a reservoir remote from the heat source and the device comprises means for transferring the oil from a reservoir to a surface of a heat-absorbing means wherein heat from the heat source is transferred by conduction to said surface to volatilise the oil.

  • Patent number: 7241727
    Abstract: The invention is concerned with post-foaming cleaning compositions which may be dispensed from a pressurised container. The compositions contain a post-foaming agent, for example a volatile hydrocarbon which boils and causes the composition to fizz on the surface of a fabric to be cleaned thereby enhancing the cleaning effect. The compositions contain high amount of volatile hydrocarbon, i.e. about 20 to 40% by weight, and a surfactant component consisting of or comprising a fatty alcohol ethoxylate.

  • Patent number: 7093949
    Abstract: A device is described which includes a vertical body, the vertical body having contained therein a wick and a source of a vaporizable material. The vertical body further includes at an open end a silky material with irregular shapes to simulate the profiles of a flame such as a candle flame. Within the vertical body is a means for supplying an air current such that, when operating, the air current passes upward causing the silky material to flutter and simulate a flame, while also entraining vaporizable material which is present in the wick.

  • Publication number: 20040188535
    Abstract: A gel air-freshener device comprising a container defining a cavity for receiving a fragrance-containing gel matrix (7), the container having an aperture (4) for permitting ingress of air into the cavity and egress of fragrance from the cavity, and having first (1) and second ends (3), which ends abut the gel-matrix (7) and move freely relative to each other as the gel matrix (7) shrinks upon evaporation of the fragrance. The device exploits the shrinkage of the gel-matrix (7) and translates this into movement of the device thereby providing a visual cue as to the condition of the gel matrix and in particular when it is exhausted.
