Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
286 words

Claim 2
Dependent Claim
286 words
A compact, self-contained regenerative filtration apparatus comprising at least one filter unit in which a first fluid is filtered for absorbing a certain component from the first fluid and a regnenerative unit for processing a second fluid used for removing the absorbed component of the first fluid from said filter unit, said filter unit including a rectangular parallelepiped casing, at least two filters disposed within said casing and each containing absorbing material for removing the certain component from the first fluid directed through said filters means including separate flow passageways and valves for the first and second fluids for selectively and separately flowing the first fluid and second fluid through said filters, said regenerative unit comprises a rectangular parallelepiped casing, means located within said regenerative casing for regenerating the second fluid, separate passageways located within said regenerative casing for supplying the first and second fluids to said filter casing and for returning the second fluid to said regeneration means after its passage to said filters in said filtered casing, means associated with said filter unit casing and said regenerative unit casing for closely interconnecting said casings with said filter casing superposed on said regenerative casing and with the connections between said passageways in said filter casing and said regenerative casing aligned for guiding the flow of first and second fluids between said flow passageways in said filter casing and said separate passageways in said regenerative casing for effecting passage of the first and second fluids from said regenerative casing to said filter casing and for returning the second fluid after its passage through said filters to said regenerative casing, and hangers secured to the upper corners of each of said filter casing and said regenerative casing.
Claim 3
Dependent Claim
54 words
A regenerative filtration apparatus, as set forth in claim 1, wherein said means for regenerating said second fluid comprises a condenser arranged to receive the second fluid from said filter unit, a separator arranged to receive the condensed second fluid from said condenser, and passageway means for flowing a cooling fluid through said condenser.
Claim 4
Dependent Claim
131 words
A regenerative filtration apparatus, as set forth in claim 1, wherein said filter unit includes a plurality of said filter casings with each said filter casing superposed on and in communication with said regenerative casing through said means for interconnecting said casings, said separate passageways in said regenerative casing includes a first passageway circuit for supplying the first fluid into each of said filter casings, a second passageway circuit for supplying the second fluid to each of said fluid casings, and a third passageway circuit for receiving the second fluid with the absorbed component from said filter casings and for directing it through said means for regenerating the second fluid and for discharging the second fluid from said regenerative unit after its passage through said means for regenerating the second fluid.
Claim 5
Dependent Claim
374 words
A compact, self-contained regenerative filtration apparatus comprising at least one filter unit in which a first fluid is filtered for adsorbing a certain component of the first fluid and a regenerative unit for processing a second fluid used for removing the adsorbed component of the first fluid from said filter unit, said filter unit comprising an elongated rectangular parallelepiped casing, at least a pair of filters disposed within said casing, means forming passageways within said filter casing comprising a first passageway system for supplying the first fluid to said filters, a second passageway system for flowing the Second fluid to said filters, a third passageway system for receiving the second fluid after its passage through said filters, and a fourth passageway system for conveying purified first fluid from said filters exteriorly of said filter casing, change-over valve means disposed in each of said first, second, third and fourth passageway systems for selectively regulating the flow of the first and second fluids through said filters, said regenerative unit including an elongated rectangular parallelepiped casing, means located within said casing for separating from the second fluid the component adsorbed from the first fluid within said filters in said filter unit, at least one first passageway within said regenerative casing for flowing the first fluid through said regenerative unit prior to passing it into said filter unit, at least one second passageway within said regenerative casing for conveying the second fluid through said regenerative unit for introduction into said filter unit, and at least one third passageway for receiving the second fluid from said filter unit and directing it through said separating means and discharging it from said regenerative unit, hangers secured to the upper corners of each of said filter casing and said regenerative casing, means located on the exterior of said filter casing and on the exterior of said regenerative casing for closely interconnecting said filter casing and regenerative casing for interconnecting said first passageway system in said filter casing to said first passageway in said regenerative casing, for interconnecting said second passageway system in said filter casing to said second passageway in said regenerative casing and for interconnecting said third passageway system in said filter casing to said third passageway in said regenerative casing.
