摘要:
Scent dispenser arrangement for dispersing fragrance into a HVAC system includes a flow sensor and a scent disperser assembly having a control module connected to the flow sensor and a canister for emitting a spray which is actuated by the control module. The flow sensor operates in response to air flow and creates an air flow dependent electrical signal transmitted to activate the control module of the spray disperser assembly. The scent disperser and flow sensor are arranged to allow the spray to be disbursed in selective locations in the HVAC system. An embodiment involves two scent disperser assemblies electrically connected in series which operate successively when the liquid in one disperser assembly is depleted or when one disperser assembly dispersers a predetermined number of sprays. A further embodiment involves pressurized containers which communicate with a scented liquid reservoir having a sprayer, wherein a pressure differential in the reservoir triggers the pressurized containers to deliver a liquid flow into the reservoir.

An aroma scent dispersing assembly which selectively meters the fragrance emittance output, varying the concentration of aroma vapor in the discharge air flow is disclosed. The dispersing assembly includes a house having interconnected base members, selectively removable cover, opposite side walls, front and end walls defining an inner compartment with at least the end wall having access openings therethrough. A motor driven forced air fan assembly is arranged in the compartment and includes controls for selectively generating a flow of air from the front wall to discharge through the access openings of the end wall. An aroma dispensing cartridge assembly is arranged in the compartment and has apertures therethrough to expose the interior to the flow of air. A scented vapor emitting source, such as one or more wafers is supported by the aroma dispensing cartridge and is exposed to the flow of air. The aroma dispensing cartridge assembly is constructed for being selectively movable to meter and vary the amount of exposure of the vapor emitting source to the flow of air.

A fiber optic polarization maintaining apparatus for use in fabrication of fused optical couplers, where the fused optical couplers include first and second optical fibers. The apparatus includes apparatus for holding the first and second optical fibers in a first predetermined alignment where the first and second fibers each include a stripped portion and where the stripped portions are held in contact along their length. Apparatus for heating the first and second optical fibers are located adjacent the holding apparatus wherein the heating apparatus is brushed across the length of the first and second fibers so as to oscillate across the fibers in an amplitude varied in an ever decreasing stepped manner until fusion of the fibers is complete.

A dispenser assembly for supporting a fragrance control unit comprising a canister and a controller or comprising a wafer support plate, fragrance wafers and a fan unit are disclosed. The controller includes a timer, a computer program for the dispersing rate, and a mechanism for activating a spray mechanism of the canister. An embodiment includes a back plate pivotally connected to a front sconce cover and having a tapered structure. Further embodiments include a sconce cover and back plate wherein studs in the sconce cover enter the back plate and the sconce cover is slid upwardly along the back plate and secured in place. Slits in the sconce cover and a top opening allows dispersion of the fragrance. Further embodiments include a sconce cover hinged to the back plate. The sconce cover includes logos and/or decorative designs, e.g. bronco, Southwestern pottery and floral arrangements with slits for dispersing the fragrance.

摘要:
An optical fiber directional coupler housing having a primary protective body substantially formed as a rectangular block with a receiving space therein. A slot in the primary protective body provides the receiving space therein. The coupled portion of the coupler to be housed is positioned in the receiving space. A resilient support material having an index of refraction less than that of the coupled portion extends into the receiving space extending between the coupled portion of the coupler which it also at least partially surrounds and the primary protective body. Plugs are typically provided at the ends of the protective body to secure the optical fibers extending from the coupled portion to the body. A heat shrinkable tubing is used as a jacket which encompasses and extends beyond the primary body.

A fiber optic polarization maintaining apparatus for use in fabrication of fused optical couplers, where the fused optical couplers include first and second optical fibers which each have a principle axis. A light launching source is coupled through a lens into a first end of a selected one of the first and second optical fibers. A piezoelectric element in combination with a solenoid applies external stress in the form of an AC modulation signal to the selected one of the first and second optical fibers. A rotating apparatus rotates the selected one of the first and second optical fibers during modulation. Apparatus for collimating light is coupled to a second end of the selected fiber. Apparatus for analyzing the collimated light is coupled to the collumating apparatus, apparatus for detecting power is coupled to the analyzing means, and an output of the power detecting apparatus is coupled to an apparatus for determining when the principle axis of the selected fiber is aligned in the direction of the externally applied stress by detecting a null output from the power detecting apparatus.
