Ionizing Structure For Ambient Air Treatment
US Patent:
6471752, Oct 29, 2002
Filed:
Oct 16, 2000
Appl. No.:
09/688338
Inventors:
Keith B. Lewis - Salt Lake City UT
Assignee:
Lewis Lint Trap, Inc. - Salt Lake City UT
International Classification:
B03C 368
US Classification:
96 20, 96 63, 96 82, 96 97, 361233, 361235
Abstract:
An ionizing structure for ambient air treatment wherein the structure, optionally having ceiling-mounting provisions, incorporates an ionizing element forwardly directed in the direction of airflow through the structure, an electrical power supply coupled to the ionizing element for applying thereto a stepped-up, negative, direct-current voltage of the order of several thousand volts, and a buffer, in effect, in the form of electrical circuit means, e. g. a filter, operatively interposed between the power supply and the blower for preventing feedback of eddy-voltage spikes, transients and the like as may be generated in the power supply to the operative parts of the blower, thus preventing damage to the blower.
Ionizing Structure For Ambient Air Treatment
US Patent:
5707429, Jan 13, 1998
Filed:
Sep 25, 1996
Appl. No.:
8/719735
Inventors:
Keith B. Lewis - Salt Lake City UT
Assignee:
Lewis Lint Trap, Inc. - Salt Lake City UT
International Classification:
B03C 341
US Classification:
96 63
Abstract:
Improved ionizing structure for ambient air treatment wherein the structure incorporates an ionizing needle directed in the direction of airflow; the needle is negatively charged to produce an electrostatic field, preferably pulsating, whereby to ionize air constituent molecules, lint, and other entrained constituents, allowing the latter simply to precipitate out of the air and fall to the ground or floor beneath; in such manner ambient air within a room enclosure, for example, is cleaned for maximizing occupant enjoyment as well as for health and other reasons.
Ion Generation Structure In Environmental Systems
US Patent:
5435837, Jul 25, 1995
Filed:
Dec 6, 1993
Appl. No.:
8/161351
Inventors:
Keith B. Lewis - Salt Lake City UT
Stewart M. Bradford - Salt Lake City UT
Stewart M. Bradford - Salt Lake City UT
International Classification:
B03C 3011
US Classification:
96 54
Abstract:
Ionization systems in and for laundry dryers and other contexts, whereby to neutralize static electricity build-up and acidic conditions, and thereby create environmentally friendly systems for drying clothes and other fabrics, generally prolonging fabric life, reducing particle and lint entrainment, and also reducing if not eliminating acidic conditions in dryers and other environs.

Appl. No.:
8/010363
Inventors:
Keith B. Lewis - Salt Lake City UT
Stewart M. Bradford - Salt Lake City UT
Stewart M. Bradford - Salt Lake City UT
International Classification:
B01D 5950
US Classification:
55319
Abstract:
A lint trap unit for fabric dryers, constructed for passive, slow-flow quiescent-zone precipitation of a majority of lint and other foreign particulates entrained in the exhaust of the dryer, and also providing for secondary filter recovery of possibly unprecipitrated residues at an upper filter that is provided.
