20100218595 | PARTICULATE FILTER AND METHOD OF USE - A particulate filter particularly suited for analytical gravimetric weighing applications is disclosed. The particulate filter includes a polytetrafluoroethylene (PTFE) media supported by a ring and yields stable microgram and submicrogram weighing results. The support ring may be PTFE, metal foil, or another non-hygroscopic polymer such that the mass of the filter does not vary with changes in atmospheric moisture. The filter simplifies the discharge of electrostatic charge buildup such that when a conductive filter media is combined with a conductive ring device, the discharge may be accomplished by placing the filter on a grounded weighing pan or other surface. The particulate filter can simplify filter identification by including identification symbols imprinted on each side of the filter media. Due to the chemically inert qualities of its components, the particulate filter is particularly suited for extraction techniques used during the detection of polycyclic hydrocarbons as is conducted in emissions and ambient air testing. | 09-02-2010 |

20090166371 | DISPENSING DEVICE - A dispensing device comprising an upright rotatable product carrousel comprising a plurality of dispensing chutes for retaining a product. The dispensing chutes are radially located about a central pivot, with a dispensing point located at a lowest point of rotation of the product carrousel. During use, removal of product from a dispensing chute located at the dispensing point results in rotation of the product carrousel to position an adjacent dispensing chute at the dispensing point, allowing for sequential removal of product from the product carrousel. | 07-02-2009 |
