Patent number: 8983278Abstract: A vaporizer device of the type which is connected to the electric mains by a plug (1), incorporating a single container (6) equipped with a body of two or more independent receptacles (8) which hold different liquid fragrances in which respective wicks (2) are immersed and a lid (9) which closes the body (7) and renders the receptacles (8) independent. The lid (9) comes with openings (10) in correspondence with the positions of the wicks (2) for the egress and vaporization of the fragrance by actuation of one or more resistance elements (3), located in opposition to the openings (10), either with use of a manual pushbutton (4) or automatically in accordance with a pre-established program, diffusing the fragrances in a sequential or combined manner during predetermined intervals of time.Type: GrantFiled: July 8, 2013Date of Patent: March 17, 2015Assignee: Zobele EspaƱa, S.A.Inventors: Julio Cesar Ruiz Ballesteros, Cedric Morhain, Ruben Garcia Fabrega, Jordi Farre Albaladejo, Andrea Caserta

Patent number: 8977115Abstract: A vaporizer for generating a vaporized chemical decontaminating agent. The vaporizer includes a primary flow path and a blower for conveying a carrier gas along the primary flow path. A secondary flow path has a first end fluidly connected to the primary flow path at a location upstream of the blower and a second end fluidly connected to the primary flow path at a location downstream of the blower. A heating element is disposed along the secondary flow path. A liquid flow path has a first end fluidly connected to a source of liquid chemical decontaminating agent and a second end fluidly connected to the secondary flow path. The liquid flow path injects the liquid chemical decontaminating agent into the secondary flow path at a location upstream of the heating element. The heating element vaporizes the liquid chemical decontaminating agent to form the vaporized chemical decontaminating agent.Type: GrantFiled: March 8, 2013Date of Patent: March 10, 2015Assignee: STERIS Inc.Inventor: Leslie Woodson Penman, Jr.

Patent number: 8903228Abstract: In a vapor delivery device, a carrier or an expedient for an active ingredient is a liquid that can be vaporized by exposure to a concentrated, focused heating point using an efficient electrical power source. The device may have a vaporizing element and an electrical power source in a housing. A switch controls supply of electrical power to the vaporizing element from the electrical power source. A tube connects a liquid reservoir to the vaporizing element. A first valve, a second valve, and a pump are generally associated with the tube. A lever pivotally supported on or in the housing may be positioned to operate the first valve, the second valve, the pump and the switch, via pivoting movement of the lever. The device efficiently provides a uniform dose of vapor with each actuation.Type: GrantFiled: March 9, 2011Date of Patent: December 2, 2014Assignee: Chong CorporationInventors: Jack Goodman, William O'Neill, Alexander Chong, William Bartkowski

Patent number: 8897629Abstract: A filament may be provided having enhanced solderability and/or heating characteristics configured for heating a substance to release an airborne scent. In exemplary implementations, the ends of a high-temperature compatible filament may be coated with a metal film having greater solderability and/or conductivity relative to the filament. The coated ends may allow the filament to be incorporated into a heating circuit using low-temperature solder, rather than by using high-temperature solder or clamping. The coated ends may have a lower resistance relative to uncoated portions of the filament such that, when electrical current is passed through the filament, most of the current will flow through the coating at the end portions of the filament concentrating heat emitted by the filament to the uncoated portions.Type: GrantFiled: January 27, 2012Date of Patent: November 25, 2014Assignee: Scent Sciences CorporationInventor: David Deacon
