Title:
FILTER TO SLOW DOWN FLOW
Document Type and Number:
WIPO Patent Application WO/2000/060960
Kind Code:
A2
Abstract:
A multiple action filter for retaining in the interior particles which are harmful to health, cause cancer or are in any case pollutants, contained in gaseous flow. The first action is to channel the flow into a conduit suitably dimensioned to increase the velocity and at the same time enhance the adhesion of the particles to be eliminated into an adequate filter element. The second action is to slow down the flow so that it no longer has the energy to detach the particles from the filter element, and the particles therefore do not reach the filter outlet.

CLAIMS
| 1. | 1) A device consisting of a body containing a conduit with a variable section in which there are one or more filter elements; it is dimensioned and structured in such a way as to be inserted in the part of a cigarette normally containing other filter elements. |
| 2. | A device as in point 1 but contained in a cigaretteholder designed for the smoking of cigarettes or cigars or in a pipe for smoking tobacco or similar. |
| 3. | A device as in point 1 but dimensioned and structured in such a way as to function in a flue or in a any discharge device. |
| 4. | A device as in point 1 but installed inside a tubular element with the function of aspiration of liquid or gas requiring filtering 5) A device as in point 1,2,3,4 composed of a series of elements designed to improve the filtering action; these elements can be the same, similar or also different. |
| 5. | A device as in points 1,2,3,4,5 but removable and not structurally fixed in such a way as to be used several time, applying it from time to time to the element to be filtered. |
| 6. | A device as in points 1,2,3,4,5 in which the filter element is replaceable while maintaining the original structure. |
| 7. | A device as in points 1,2,3,4,5,6,7 installed or installable together with other types of filters which can mutually form parts of the same filter. |
| 8. | A device installed or to be installed in an"antismog mask"for filtering the air breathed. |
