US3594989A — Collapsible and disposable collecting cell for el…

Claim 1

Independent Claim 459 words

A disposable and collapsible cell for an electrostatic gas cleaner gas cleaner comprising, a first set of electric conducting sheets, a second set of electric conducting sheets, each of said sheets of said first set being interposed between adjacent sheets of said second set so that every other conducting sheet is of the same set, a plurality of electric insulating sheets each being interposed between adjacent conducting sheets, thus starting with a conducting sheet at one side there is a sheet of said first set, an insulating sheet, a sheet of said second set, an insulating sheet and so on, throughout the cell, means for connecting adjacent sheets along common portions running on one direction, said common portions for said first set of sheets and said insulating sheets on opposite sides thereof being spaced a predetermined distance along said first sheet of said first set in a second direction at right angles to said one direction, every other of said common portions of said first sheets being connected to the insulating sheet on the opposite side of said first sheet, said common portions for said second set of sheets and said insulating sheets on opposite sides thereof being spaced a predetermined distance along said sheet of said second set in said second direction, every other of said common portions of said second set being connected to the insulating sheet on the opposite side of said second sheet, thus said insulating sheets are alternatively connected to a conducting sheet of said first set and a conducting sheet of said second set, the three sets of sheets upon being expanded from a collapsed position forming a honeycomblike cell adapted to receive air therethrough in said one direction, means adapted to connect said first set of sheets to a source of power, means adapted to connect said second set of sheets to a source of power, first and second oppositely positioned supporting base sheets adapted to be brought together when said cell is collapsed and drawn apart when said cell is expanded, means flexibly connecting respective portions extending in the one direction of the uppermost one of said superposed sheets to said first base sheet in a manner to permit movement of the connections in the same plane but at right angles to the directions of connection, and means flexibly connecting respective portions extending in the one direction of the lowermost one of said superposed sheets to said second base sheet in a manner to permit movement of the connections in the same plane but at right angles to the direction of the connection so as to allow for contraction of the cell in the direction at right angles to the one direction when it is expanded in another direction perpendicular thereto.

Claim 2

Dependent Claim 459 words

A disposable and collapsible cell for an electrostatic gas cleaner gas cleaner comprising, a first set of electric conducting sheets, a second set of electric conducting sheets, each of said sheets of said first set being interposed between adjacent sheets of said second set so that every other conducting sheet is of the same set, a plurality of electric insulating sheets each being interposed between adjacent conducting sheets, thus starting with a conducting sheet at one side there is a sheet of said first set, an insulating sheet, a sheet of said second set, an insulating sheet and so on, throughout the cell, means for connecting adjacent sheets along common portions running on one direction, said common portions for said first set of sheets and said insulating sheets on opposite sides thereof being spaced a predetermined distance along said first sheet of said first set in a second direction at right angles to said one direction, every other of said common portions of said first sheets being connected to the insulating sheet on the opposite side of said first sheet, said common portions for said second set of sheets and said insulating sheets on opposite sides thereof being spaced a predetermined distance along said sheet of said second set in said second direction, every other of said common portions of said second set being connected to the insulating sheet on the opposite side of said second sheet, thus said insulating sheets are alternatively connected to a conducting sheet of said first set and a conducting sheet of said second set, the three sets of sheets upon being expanded from a collapsed position forming a honeycomblike cell adapted to receive air therethrough in said one direction, means adapted to connect said first set of sheets to a source of power, means adapted to connect said second set of sheets to a source of power, first and second oppositely positioned supporting base sheets adapted to be brought together when said cell is collapsed and drawn apart when said cell is expanded, means flexibly connecting respective portions extending in the one direction of the uppermost one of said superposed sheets to said first base sheet in a manner to permit movement of the connections in the same plane but at right angles to the directions of connection, and means flexibly connecting respective portions extending in the one direction of the lowermost one of said superposed sheets to said second base sheet in a manner to permit movement of the connections in the same plane but at right angles to the direction of the connection so as to allow for contraction of the cell in the direction at right angles to the one direction when it is expanded in another direction perpendicular thereto.

Claim 3

Dependent Claim 164 words

The invention of claim 1 in which thEre are a plurality of first support bars slidably mounted on the opposing face of said first base sheet for movement in the same plane but at right angles to said one direction, a plurality of second support bars slidably mounted on the opposing face of said second base sheet of movement in the same plane but at right angles to said one direction, the uppermost one of said superposed sheets being connected along respective portions extending in the one direction to respective ones of said first support bars, and the lowermost one of said superposed sheets being connected along respective portions extending in the one direction to respective ones of said second support bars in a manner such that said first and second support bars are movable towards each other when said cell is expanded from the collapsed state and are movable away from each other as said cell is contracted back to the collapsed state.

Claim 4

Dependent Claim 58 words

The invention of claim 1 in which the widths of the insulating sheets between adjacent conducting sheets are greater than in width in the one direction than the widths of the conducting sheets extending in the one direction whereby to provide an overhang of insulating sheets in the one direction relative to the conducting sheets at each end.

Claim 5

Dependent Claim 55 words

The invention of claim 2 in which the widths of each of said support bars in their directions of movement are chosen to cause the bars to abut each other and limit the degree of movement of the bars towards each other as the cell is expanded and thereby limit the expansion of the cell.
