Patent CA-2259005-C (CA)
Inventor: BAUSE DANIEL E
IPC: B01D53/18
Filed: 1997-06-19
Granted: 2006-03-14
Abstract: A unique filtration method and device (10) which continuously removes several gas phase contaminants from an air stream through the use of partially hollow wicking fibers (20) impregnated with a selected liquid whic h can capture the gas phase contaminants. The wicking fibers (20) are generally disposed parallel and are formed into a filter element (12) which extends from the air stream to be cleaned into another air stream which can strip and carry away the unwanted gas phase contaminants. The gas phase contaminants are conveyed to the stripping air stream by a concentration factor induced molecular migration. The air stream to be cleaned is directed through a compartment (16) across which the filter element (12) extends so the complete air flow is through filter element (12). Filter element (12) al so extends into another compartment (18) through which the stripping air stream flows. The wicking fibers (20) include internal longitudinal cavities (22) each with a relatively small longitudinal extending opening (24). The wicking fibers (20) are filled with the selected contaminant removing liquid through capillary action by which the individual wicking fibers (20) rapidly draw the selected liquid, with which they come into contact, through the internal cavities (22 ). The absorption liquid remains within the wicking fiber cavities (22) an d generally does not enter the space between the wicking fibers yet through th e longitudinal openings (24) the liquid is in full communication with the air stream flowing past the fibers (20).

Abstract: Ensemble mat (10) se plaçant à l'arrière d'un tableau de bord, destiné à être installé dans un véhicule et comprenant une couche antibruit (12) fixée à une couche absorbante (14). La couche antibruit (12) est composée d'un matériau relativement rigide tandis que la couche absorbante (14) est composée d'un matériau relativement souple. La surface interne de la couche antibruit (12) est en contact direct avec la surface externe de la couche absorbante. Des éléments de fixation (16) sont prévus pour fixer les couches ensemble. Chaque élément de fixation comprend une cheville allongée (22) dotée d'extrémités opposées et d'une collerette de retenue souple (24, 26), moulée en une seule pièce avec la cheville (22), à chacune de ses extrémités. Les collerettes (24, 26) s'étendent généralement de manière transversale par rapport à un axe central de la cheville et la longueur de chaque collerette est supérieure à la dimension de section de la cheville. Les dispositifs de fixation (16) traversent entièrement la couche antibruit (12) et peuvent s'étendre partiellement ou entièrement à travers la couche absorbante (14). La longueur de la cheville (22) est inférieure aux épaisseurs combinées des couches, de sorte que celles-ci soient maintenues ensemble sous compression. Un procédé de fixation des couches est également décrit.

Granted: 2008-12-30
Abstract: The present invention is a device to place an incision into matter (32) with a harmonious plasma cloud. A radio frequency generator system (10) produces electromagnetic waveform which is transmitted by an active transmitter incising electrode tip (28). This electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization, and a photoelectric effect which then triggers an avalanche effect for charged atomic particles at the surface of the active transmitter incising electrode tip (28). This electromagnetic wave is impedance matched, frequency matched, power matched, tuned to the plasma cloud in order to sustain, control a harmonious plasma cloud which demonstrates reduced atomic particle turbulence, and chaos while forming a coating over the surface of the active transmitter incising electrode tip (28). The magnetic bottle effect, the pinch effect, a nd the tunnelling effect are employed to trap, contain, compress, contour, focus, and amplify the energy of the incising plasma cloud.
