Patent number: 8178048Abstract: A dispenser fixture for dispersing aromatic vapors into a facility includes an elongated dispenser chamber bounded by end walls, one containing a motor driven fan and the other wall containing fixtures for supplying and controlling electrical current for powering the fan motor. The chamber, containing trays supporting a replaceable supply of aromatic material, presents the aromatic material to an air flow passing into apertures positioned near or in the other wall such that a carrier arm supporting the fixture orientates the fan motor to discharge air enriched with aromatic vapors in a horizontal direction into the facility. The fixture includes upstanding side walls joining the end walls, a floor wall joining the side walls and the end walls, and a top wall overlying the side and end walls for enclosing the aromatic materials in the chamber. The dispenser fixture may be made of a hard plastic or metal.Type: GrantFiled: March 6, 2009Date of Patent: May 15, 2012Assignee: Pestco, Inc.Inventors: Arnold H. Zlotnik, Raymond Czapko

Publication number: 20120079945Abstract: An air freshener dispensing register cover covers an air register and causes the airstream exiting from the air register to be filtered and to pass over a fragrance oil cartridge. The fragrance oil cartridge has diffusion paper saturated with fragrance oil. The components of the register cover are a base, a cartridge holder, a cutter and a top. The base has an opening and is sized to be positioned over an air register. The cartridge holder is attached to the base and holds a fragrance oil cartridge within the airstream exiting from the register. The cartridge holder and cutter cooperate to break a seal within the cartridge to release the fragrance oil within the cartridge. The top covers the base and has openings through which the airstream exits. The amount of fragrance oil remaining within the cartridge may be viewed through a transparent section of the register cover.Type: ApplicationFiled: October 4, 2010Publication date: April 5, 2012Inventor: Randy W.

Publication number: 20120060695Abstract: A high-velocity-air filter apparatus for filtering air passing through air supply vents in air conditioning systems includes a metal wire grid support, a nylon mesh air filter that rests on top of the metal wire grid support, and a metal peripheral frame attached to and surrounding the peripheral edges of both of the metal wire grid support and the nylon mesh air filter. The high-velocity-air filter apparatus is washable, reusable, antibacterial and mildew-proof. The high-velocity-air filter apparatus minimizes the resistance to air-flow, allowing up to 125% of the nominal air flow rate through the air supply vent. The high-velocity-air filter apparatus is extremely thin, less than 0.1875 inches, to allow for maximum adaptability to air supply vents and to minimize air resistance.Type: ApplicationFiled: November 21, 2011Publication date: March 15, 2012Inventor: Helena Hepburn
