The air flows through a first side of the air filter and is measured on the second side of the air filter by utilizing a wind meter or similar device to gauge the amount of air flow velocity of the second side of the filter. Additionally, the apparatus and system utilizes a display means to illustrate the differing air velocity through the second side of the air filter. | 11-27-2008 |

| 20090308254 | HANDHELD CLEANING APPLIANCE - A cleaning appliance includes a main body, a filter and an interlock. The main body includes an airflow generator, a separating apparatus separating dirt and dust from an airflow, and a flowpath between the separating apparatus and the airflow generator delimited by a wall. The interlock has a first part located on the filter and a second part located on the main body outside the flowpath, arranged to communicate remotely when the filter is correctly located in the pre-determined position. The interlock is arranged selectively to allow or prevent operation of the airflow generator depending upon the relative separation between the first and second parts. By providing an interlock which has first and second parts which communicate remotely, the second part located on the main body can be isolated from the airflow path so that the second part is not subject to dirt and dust carried by the airflow. | 12-17-2009 |
| 20100077926 | DUST CAPTURE DEVICE AND PROJECTION TYPE IMAGE DISPLAY APPARATUS - The present invention includes: a rolled filter stretched between first and second winding shafts and, unused part of the filter being wound around the second winding shaft; a brush provided between the first and the second winding shafts so as to come into contact with a surface of the filter; a feeding mechanism for driving the first and the second winding shafts to take up or rewind the filter; and a feeding control unit for controlling the feeding mechanism. When activating a renewing operation for feeding unused part of the filter from the second winding shaft, the feeding control unit controls the feeding mechanism such that once the filter is taken up by the first winding shaft by an take-up amount La, the filter is rewound by the second winding shaft by a rewind amount Lb, and La and Lb satisfy a relationship La≧Lb. Without increasing the amount of the filter or the size of the device itself, the present invention can deliver adequate performance even in a dusty environment by a small number of filter renewing operations. | 04-01-2010 |
| 20100288128 | FILTER CASSETTE MAGAZINE AND APPARATUS FOR SEQUENTIALLY GATHERING FINE PARTICLES USING THE SAME - Disclosed is a filter cassette magazine and an apparatus for sequentially gathering fine particles using the same, in which a ‘filter cassette not having gathered fine particles yet,’ is received from a first magazine and the received filter cassette is transferred to a lower portion of an upper filter holder, the ‘filter cassette not having gather fine particles yet’ is pushed up toward the upper filter holder by lifting a lower filter holder so as to gather fine particles from outside, the ‘filter cassette having gathered fine particles’ is transferred to a lower portion of a second magazine, and the ‘filter cassette having gathered fine particles’ is pushed up and stored into the second magazine by lifting a push rod. Therefore, it is possible to implement simple maintenance and management, reduction in malfunction, and reduction in parts for machines and equipment. | 11-18-2010 |
| 20110100226 | Marine Water Separating Fuel Filter - A marine water separating fuel filter includes a connecting tube head, an upper lid, a filter element, and a container. The filter element is accommodated in the container and sealed by the upper lid, with an axial trough and a limiting ring provided on a hollow taper post to hold against the filter element. An axial rod of the connecting tube head is screwed to the axial trough. The connecting tube head has a pressing ring to hold against a washer, providing a sealing function. The gas from an inlet end is filtered with the filter element and then expelled through an outlet end. An indication ring is provided on the hollow taper post to indicate the height of liquid. This is an easy and quick way to assemble and disassemble the filter element, providing environmental and economical purposes. | 05-05-2011 |
| 20130174742 | Self Adjusting Filter Mass Area That Produces Extended Filter Life And Uniform Static Pressure Throughout - Improvements in a filter where the filter self-expands based upon increased pressure or vacuum in the filtering stream. The expandable filter is adaptable to filtering a wide variety of media including air used in HVAC units, gases that are used to filter impurities out of gases and for industrial applications. The expandable filter to maintain a constant pressure or vacuum in the plenum or filter. The filter self-expands as the pressure or vacuum increases and pushes, pulls or draws the filter into an elongated or heightened configuration. As the filter expands new filter material is exposed that was not previously exposed for filtering. Expansion doubles, triples, or further increases the filter collection surface area. The filter does not rely upon gravity and expands based upon the increase of pressure or vacuum in the plenum the filter can be arranged in a vertical or horizontal orientation. | 07-11-2013 |
