Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
161 words
A device for following the variations in the composition of a flowing heterogeneous mixture of at least two liquid phases incompletely miscible with each other, the device comprising: (a) means for sampling an adjustably selected amount of the flowing mixture to provide a sample thereof, (b) means for measuring the amount of said sample, (c) means connected to said sampling means, for separating at least one liquid phase from said sample of the mixture, (d) means for measuring the amount of the so-separated liquid phase, (e) means for displaying the measured values of the amounts of said sample of mixture and of said separated liquid phase, said displaying means being connected to both of said amount measuring means, and, means for recycling at least one liquid phase issuing from said separating means, said recycling means being connected to said separating means and to the flow of heterogeneous mixture downstream of the point where said sampling means is connected to said flow.
Claim 2
Independent Claim
161 words
A device for following the variations in the composition of a flowing heterogeneous mixture of at least two liquid phases incompletely miscible with each other, the device comprising: (a) means for sampling an adjustably selected amount of the flowing mixture to provide a sample thereof, (b) means for measuring the amount of said sample, (c) means connected to said sampling means, for separating at least one liquid phase from said sample of the mixture, (d) means for measuring the amount of the so-separated liquid phase, (e) means for displaying the measured values of the amounts of said sample of mixture and of said separated liquid phase, said displaying means being connected to both of said amount measuring means, and, means for recycling at least one liquid phase issuing from said separating means, said recycling means being connected to said separating means and to the flow of heterogeneous mixture downstream of the point where said sampling means is connected to said flow.
Claim 3
Dependent Claim
14 words
A device according to claim 1, wherein said separating means comprises continuous centrifuging means.
Claim 4
Independent Claim
24 words
A device according to any of claims 1 or 2, wherein said sampling means is directly connected to the flow of said heterogeneous mixture.
Claim 5
Independent Claim
25 words
A device according to any of claims 1 and 2, wherein said sampling means is connected to a derivation of the flow of heterogeneous mixture.
Claim 6
Dependent Claim
22 words
A device according to claim 1, comprising a sensor positionable in the flowing mixture at an adjustable distance from the flow axis.
Claim 7
Dependent Claim
25 words
A device according to claim 1, wherein said sampling means is an intermittently operating device adapted to effect sampling according to a preselected time schedule.
Claim 8
Dependent Claim
33 words
A device according to claim 1, wherein said sampling means is an intermittently operating device provided with means for controlling the sampling frequency as a function of the flow rate of heterogeneous mixture.
Claim 9
Dependent Claim
35 words
A device according to claim 1, wherein said sampling means is continuously operating and is provided with means for controlling the sampled flow rate as a function of the flow rate of the heterogeneous mixture.
Claim 10
Dependent Claim
47 words
A device according to claim 1, further comprising additional means for calculating a ratio ΔS 2 /ΔS 1 , wherein ΔS 2 is the variation of said measured amount of separated liquid phase corresponding to a slight variation ΔS 1 in said measured amount of sampled mixture.
Claim 11
Dependent Claim
25 words
A device according to claim 9, further comprising alarm means adapted to be actuated when the ratio ΔS 2 /ΔS 1 exceeds a preselected limit-value.
Claim 12
Dependent Claim
40 words
A device according to claim 1, which can be used for heterogeneous mixtures also containing a solid phase, wherein said separating means is of a type permitting discharge of the solid phase without interrupting the operation of said separating means.
Claim 13
Dependent Claim
14 words
The device of claim 1, wherein said sampling means is of variable sampling rate.
Claim 14
Dependent Claim
14 words
The device of claim 1, wherein said separation means is a continuous separating means.
