Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
122 words
A device for separating liquids of different densities in flow streams subjected to periodic increase above normal flow rate comprising: a first separator for receiving and separating the liquids at said normal flow rate including means to conduct the liquids thereto: a second separator for separating the liquids at flow rates above normal; concentrating means having a bottom and including means for transmitting the less dense liquid with components of the more dense liquid separated by said first separator thereto, and means for separating and transmitting components of the more dense liquid from said concentrating means to said second separator; and means to bypass said first separator and conduct the inflow of liquids to said second separator at flow rates above normal.
Claim 2
Independent Claim
122 words
A device for separating liquids of different densities in flow streams subjected to periodic increase above normal flow rate comprising: a first separator for receiving and separating the liquids at said normal flow rate including means to conduct the liquids thereto: a second separator for separating the liquids at flow rates above normal; concentrating means having a bottom and including means for transmitting the less dense liquid with components of the more dense liquid separated by said first separator thereto, and means for separating and transmitting components of the more dense liquid from said concentrating means to said second separator; and means to bypass said first separator and conduct the inflow of liquids to said second separator at flow rates above normal.
Claim 3
Dependent Claim
26 words
A device in accordance with claim 1 wherein said means for separating comprises decanting means connecting the bottom of said concentrating means to said second separator.
