53950569, Mar 7, 1995

Filed:

Jun 15, 1993

Appl. No.:

8/077311

Inventors:

Timothy J. Perry - Danville CA

International Classification:

B02C 1912

US Classification:

241 19

Abstract:

The uniformity and suitability of fractural glass derived from breaking used fluorescent tubes for separation of the glass and potentially toxic powder adhered to the fractured glass prior to disposal and recovery of the components glass and powder is improved by use of a fracture blade having a sharp striking point extending forwardly from a base composed of a flat transversely oriented rotatable striking blade. The blade is preferably, for best results in later separation of the glass particulates and powder, operated at a striking blade speed of 1760 to 3700 feet per minute, providing a uniformity and size of fractured glass upon which a significantly more effective countercurrent air separation can be made.

Filed:

May 7, 1987

Appl. No.:

7/047894

Inventors:

Timothy J. Perry - Danville CA

Assignee:

Mello Manufacturing, Inc. - Richmond CA

International Classification:

B01D 4600

US Classification:

55381

Abstract:

A vacuum cleaner uses a special self-cleaning filter arrangement including an initial fabric filter having a relatively large mesh size with a broad open mesh ratio of 5 to 15% and a total opening area of 5 to 45 times the cross section of the inlet, which inlet faces away from the filter. The initial filter is preferably backed up by secondary filters and is arranged so that dirt collected on the filter is periodically sloughed off and dropped into a receptacle after building to a critical level.

Timothy J. Perry - Danville CA

International Classification:

B02C 1912

US Classification:

241 19

Abstract:

The separation of potentially toxic phosphor compounds from fractured glass particulates derived from crushing used fluorescent light tubes is improved by continuously mixing the fractured glass particulates together in surface contact with each other to abrade the toxic phosphors from the surfaces of the glass particulates followed by separation by air stripping of the small phosphor particles from the fractured glass particulates. The stripping usually is done in a separate stripping chamber. The mixing and abrading may be accomplished in a variety of mixing devices including auger-type apparatus, rotary chambers, fluosolids reactors and others.

7/638383

Inventors:

Timothy J. Perry - Danville CA

Assignee:

Mello Manufacturing Inc. - Richmond CA

International Classification:

B01D 4600

US Classification:

55 97

Abstract:

A vacuum cleaner uses a special self-cleaning filter arrangement including an initial fabric filter having a relatively large mesh size with a broad open mesh ratio of 5 to 11 flat filter threads 0. 025 to 0. 045 inches in width defining oblong filter openings 0. 002 to 0. 006 inches in width between longitudinal strands having substantially flat upstream surfaces and having a length between transverse strands not greater than will maintain the structural integrity of the filter openings and a total opening area of 5 to 45 times the cross section of the inlet, which inlet faces away from the filter. The initial filter is preferably backed up by secondary filters which filter particulates passing through the initial fabric filter especially during startup and while the filter cleans itself. Various elements for strengthening the longitudinal strands to maintain the structural integrity of the filter medium with relatively long or extended filter openings are provided.

Assignee:

Mercury Technologies Corporation - Benicia CA

International Classification:

B02C 1912

US Classification:

241 19

Abstract:

A digesting system for disposal and separation of the component materials, including potentially toxic materials, from used fluorescent tubes, which breaks up fluorescent tubes with a rotating fracture blade while passing a critical amount of stripping air through the fracture zone and countercurrently through a countercurrent flow zone with the fractured glass. The small dust and powder particulates separated from the glass by the countercurrent air stream are then separated from the air stream by a sequence including an initial cyclone or the like from which particulate material collected may be removed during continued operation and by subsequent fine filter means and a final activated carbon filter to remove metallic vapors.

Inventors:

Timothy J. Perry - Danville CA

International Classification:

B02C 2338
B02C 2340

US Classification:

241 14

Abstract:

A grizzly-type separator is disposed across the path of fractured glass particulates to separate electrical tips from said glass particulates. The separator is formed preferably from round separator bars of about twice the average maximum diameter of fractured glass and about equal to the maximum average diameter of the fractured glass particulates. The separator bars are discontinuous in the center to cause a change in orientation of objects moving down the bars and are secured together by cross bars spaced significantly from the separator bars.

Appl. No.:

Inventors:

Timothy J. Perry - Danville CA

International Classification:

B02C 1912

US Classification:

241 19

Abstract:

A digesting system for disposal and separation of the component materials, including potentially toxic materials, from used fluorescent tubes, wherein the fluorescent tubes are fractured with a rotating fracture blade while passing stripping air through the fracture zone and the fractured glass is then passed countercurrently through a countercurrent flow zone with a rapid flow of stripping air. As the fractured glass particulates descend or fall through the countercurrent flow stripping gas zone, they impact upon a plurality of baffles or impact surfaces that jar the particulates separating additional small powder particulates from the surface of the glass particles. The small dust or powder particulates separated from the glass by the air stream and the jarring surfaces are then separated from the air stream by a sequence including an initial cyclone or the like from which particulate material collected may be removed during continued operation and by subsequent fine filter means and a final activated carbon filter to remove metallic vapors.
