Plural Reversely Extending Passages Patents (Class 131/213)
  • Patent number: 11986018
    Abstract: An aerosol generation system for generation of an aerosol from an aerosol-forming precursor includes an electrically operated heating system to heat precursor to generate the aerosol, a flow path for transmission of flow, including the aerosol, to a user, the heating system arranged in fluid communication with the flow path; and electrical circuitry. The electrical circuitry is configured to: measure a property of the electrical energy through the heating system, determine one or more characteristics from the result of the measurement of the measured property of the electrical energy, select, based on the determined characteristics, one from a plurality of different stored relationships between the measured property of the electrical energy and a property of the flow, and determine the property of the flow based on relationship.

  • Patent number: 11596174
    Abstract: Phyto material tablets, tablet vaporizers, methods and apparatus for forming phyto material tablets. The tablets are formed to increase vaporization efficiency. Tablets can include break regions to facilitate fracturing into multiple pieces for vaporization. The tablets can also include multiple layers of different phyto material mixtures. Compression molds are used to shape the tablets. The compression molds can be provided on a rotational assembly to facilitate rapid manufacturing of multiple tablets. The vaporizers include heating chambers that are configured to increase the surface area of the tablets exposed for vaporization. The heating chambers include compression or fracture members that compress and/or encourage fracturing of the tablets to assist vaporization.

  • Patent number: 5676163
    Abstract: The invention is concerned with a process for counteracting smoke malodour wherein enclosed air spaces wherein smoke maladour is present, or substrates on which smoke malodour has deposited are brought in contact with one or more perfumery aldehydes of the class I according to general structure, wherein R1 and R2 each may be: hydrogen, alkyl, hydroxyl or alkoxy, or together may be methylenedioxy or with a perfume containing such aldehydes. Preferably the perfume also contains one or more perfumery aldehydes of class according to general structure, wherein R1 is a phenyl ring optionally substituted with an alkyl group, R2 represents hydrogen or both R2 taken together represent a double bond, and R3 is hydrogen or an alkyl chain with 1 to 6 carbon atoms. The smoke malodour counteracting perfumes preferably contain at least 3.5% w/w of class I aldehydes and at least 10% w/w of class II aldehydes.

  • Patent number: 4993435
    Abstract: A smoking accessory includes a case that can completely contain a lighted cigarette. The cigarette foot end extends out of the case, and the smoker exhales smoke into a mouthpiece on the case that conducts the exhaled smoke into a filter chamber to be filtered before it is exhausted to the environment. The case includes an ash chamber next to a cigarette containing chamber, and a filter chamber is located adjacent to the cigarette containing chamber. A flexible hose having two passages can be connected to the case.
