Abstract
Abstract Profile elements are provided for enriching or purifying substances that have different states, i.e., an environmental material and a fluid material. The profile elements for supply or removal of fluid substances to or from granulated, fibrous, or soil-like material in the environment surrounding the profile elements comprise a plurality of spaced apart webs and boundary walls that connect to webs and are supported by them. These elements then define a plurality of longitudinal channels arrayed side-by-side between the webs. The boundary walls are shaped to have a surface area substantially greater than equivalent flat walls. At least a portion of the webs and the boundary walls is pierced or perforated, as if a mesh or lattice, to permit fluid communication between adjacent channels and/or between the channels and the surrounding environment.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
126 words
Profile elements of the type employed for supply or removal of fluid substances from granulated, fibrous, or crumbly soil-like material in an environment surrounding the profile elements comprising: a plurality of spaced apart webs; and associated boundary walls integrally connecting said webs and supported upon said webs so as to define a plurality of longitudinally arrayed side-by-side channels separated by respective ones of said webs, with each said web constituting a common side wall for adjacent channels; said boundary walls being shaped to provide an enlarged surface area compared to planar walls extending over an equivalent base area; said webs and said boundary walls being formed from an apertured mesh-like fabric to enable fluid communication between adjacent channels and between the channels and the surrounding environment.
Claim 2
Dependent Claim
126 words
Profile elements of the type employed for supply or removal of fluid substances from granulated, fibrous, or crumbly soil-like material in an environment surrounding the profile elements comprising: a plurality of spaced apart webs; and associated boundary walls integrally connecting said webs and supported upon said webs so as to define a plurality of longitudinally arrayed side-by-side channels separated by respective ones of said webs, with each said web constituting a common side wall for adjacent channels; said boundary walls being shaped to provide an enlarged surface area compared to planar walls extending over an equivalent base area; said webs and said boundary walls being formed from an apertured mesh-like fabric to enable fluid communication between adjacent channels and between the channels and the surrounding environment.
Claim 3
Dependent Claim
16 words
Profile elements as in claim 1, wherein said webs or said walls include additional wick-like material.
Claim 4
Dependent Claim
19 words
Profile elements as in claim 1 wherein said channels are at least partly filled with an effective filtering substance.
Claim 5
Dependent Claim
14 words
Profile elements as in claim 3 wherein said filtering substance includes a filter packing.
Claim 6
Dependent Claim
14 words
Profile elements as in claim 1 wherein said filtering substance includes an active carbon.
Claim 7
Dependent Claim
19 words
Profile elements as in claim 1, wherein said webs or said walls further include additional material which is hydrophobic.
Claim 8
Dependent Claim
86 words
Profile elements of the type employed for supply of fluid substances to or removal of fluid substances from granulated, fibrous, or crumbly soil-like material in an environment surrounding the profile elements comprising: boundary walls shaped to define a multi-tubular construction of tubes integrally connected side-by-side in longitudinal array so as to have at least a portion of the walls common to adjacent ones of said tubes, said walls being formed from an apertured mesh-like fabric enabling fluid communication between the tube interiors and the surrounding environment.
Claim 9
Dependent Claim
86 words
Profile elements of the type employed for supply of fluid substances to or removal of fluid substances from granulated, fibrous, or crumbly soil-like material in an environment surrounding the profile elements comprising: boundary walls shaped to define a multi-tubular construction of tubes integrally connected side-by-side in longitudinal array so as to have at least a portion of the walls common to adjacent ones of said tubes, said walls being formed from an apertured mesh-like fabric enabling fluid communication between the tube interiors and the surrounding environment.
Claim 10
Dependent Claim
143 words
A process of supplying fluid substances to or removal of fluid substances from granulated, fibrous, or crumbly soil-like material by use of profile elements that include a plurality of spaced apart webs and associated boundary walls that integrally connect the webs and are supported upon the webs so as to define a plurality of longitudinally arrayed side-by-side channels separated by respective ones of the webs, with each said web constituting a common side wall for adjacent channels, and with the boundary walls being shaped so as to provide an enlarged surface area as compared with planar walls extending over an equivalent base area; with the webs and the boundary walls being formed of an apertured mesh-like fabric to enable fluid communication both between the adjacent channels and with the surrounding environment, comprising the step of flowing said fluid substances through said profile elements.
Claim 11
Dependent Claim
143 words
A process of supplying fluid substances to or removal of fluid substances from granulated, fibrous, or crumbly soil-like material by use of profile elements that include a plurality of spaced apart webs and associated boundary walls that integrally connect the webs and are supported upon the webs so as to define a plurality of longitudinally arrayed side-by-side channels separated by respective ones of the webs, with each said web constituting a common side wall for adjacent channels, and with the boundary walls being shaped so as to provide an enlarged surface area as compared with planar walls extending over an equivalent base area; with the webs and the boundary walls being formed of an apertured mesh-like fabric to enable fluid communication both between the adjacent channels and with the surrounding environment, comprising the step of flowing said fluid substances through said profile elements.
Claim 12
Dependent Claim
36 words
The process of claim 8 wherein said fluid substances include liquids and said flowing includes initially flowing said liquid at a controlled, rapid supply rate, and thereafter flowing said liquid at a lower basic supply rate.
Claim 13
Dependent Claim
26 words
The process of claim 8, wherein load pressure introduced from said environment and said fluid is distributed evenly over a supporting surface for said profile element.
Claim 14
Dependent Claim
15 words
The process of claim 10, wherein said profile elements are arranged in a sandwiched configuration.
Claim 15
Dependent Claim
15 words
The process of claim 10 wherein said profile elements are arranged in a multi-tubular configuration.
Claim 16
Dependent Claim
25 words
The process of claim 8, wherein said profile elements are formed of a strong, stiff material, thereby omitting shaping containers, base supports, and the like.
