Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A device for determining the relative location of stratified fluids of different character when inserted through the stratified fluids comprising: an elongated member having plural fluid character recording stations disposed therealong; sensing means associated with each of said stations for determining the properties of the fluid proximate thereto when said probe is positioned through said fluids; clearing means movably associated with each of said sensing means to preclude contamination thereof by fluid from other strata; and means to determine the fluid characteristics recorded by said stations.
Claim 2
Independent Claim
86 words
A device for determining the relative location of stratified fluids of different character when inserted through the stratified fluids comprising: an elongated member having plural fluid character recording stations disposed therealong; sensing means associated with each of said stations for determining the properties of the fluid proximate thereto when said probe is positioned through said fluids; clearing means movably associated with each of said sensing means to preclude contamination thereof by fluid from other strata; and means to determine the fluid characteristics recorded by said stations.
Claim 3
Dependent Claim
80 words
A device in accordance with claim 1 wherein said recording stations comprise optical windows in said member and wherein said means to determine the fluid characteristics comprise filber-optic conductors connected to each of said windows at one end to a remote recording station at the other end for remote determination of the properties of said fluids; said device further comprising a light source associated with said member to provide illumination for determination of the properties of said fluids where required.
Claim 4
Dependent Claim
30 words
A device in accordance with claim 1 wherein said recording stations comprise independent chambers formed in said member and wherein said sensing means comprises individual ports communicating with said chambers.
Claim 5
Dependent Claim
51 words
A device in accordance with claim 1 wherein said clearing means comprises means to block said sensing means in a first position when said member is transiting said fluids and to unblock said sensing means when moved to a second position to provide for recordation of the characteristics of said fluids.
Claim 6
Dependent Claim
55 words
A device in accordance with claim 3 wherein said means to block comprises a sheath movably enclosing said elongated member, said sheath having orifice means therethrough movable from said first position with said orifice means out of alignment with said sensing means to a second position with said orifice means aligned with said sensing means.
Claim 7
Dependent Claim
21 words
A device in accordance with claim 4 wherein said orifice means comprises a port corresponding to each of said sensing means.
Claim 8
Dependent Claim
48 words
A device in accordance with claim 3 wherein said means to block comprises covering means movable from a first position with said sensing means in alignment therewith to cover said sensing means to a second position with sensing means out of alignment therewith to uncover said sensing means.
Claim 9
Dependent Claim
58 words
A device in accordance with claim 1 wherein said clearing means comprises wiping means movable between a first position adjacent one side of said sensing means to a second position adjacent to the other side of said sensing means to thereby wipe said sensing means clear of any contaminant prior to recordation of the characteristics of said fluid.
Claim 10
Dependent Claim
44 words
A device in accordance with claim 8 wherein said wiping means comprises a wiping ring in wiping contact with said elongated member proximate each of said sensing means, and connecting means to simultaneously move said rings from said first position to said second position.
Claim 11
Dependent Claim
18 words
A device in accordance with claim 1 wherein movement of said clearing means is rotary of said member.
Claim 12
Dependent Claim
18 words
A device in accordance with claim 1 wherein movement of said clearing means is longitudinal of said member.
