Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
An apparatus for controlling the flow of fluid through a flow line comprising: a. a housing adapted to be mounted about said flow line; b. a flow blocking means mounted in said housing for movement toward said flow line; c. moving means for moving said flow blocking means into engagement with said flow line; and d. said flow blocking means including a cutting head with means for rotating same for cutting into the flow line as the said moving means moves said cutting head into engagement with said flow line and a conical section having a generally conical shape whereby, as said moving means causes said conical section to engage said flow line, said flow line is sheared into two portions such that said flow line is deformed to prevent flow therethrough.
Claim 2
Independent Claim
132 words
An apparatus for controlling the flow of fluid through a flow line comprising: a. a housing adapted to be mounted about said flow line; b. a flow blocking means mounted in said housing for movement toward said flow line; c. moving means for moving said flow blocking means into engagement with said flow line; and d. said flow blocking means including a cutting head with means for rotating same for cutting into the flow line as the said moving means moves said cutting head into engagement with said flow line and a conical section having a generally conical shape whereby, as said moving means causes said conical section to engage said flow line, said flow line is sheared into two portions such that said flow line is deformed to prevent flow therethrough.
Claim 3
Independent Claim
132 words
An apparatus for controlling the flow of fluid through a flow line comprising: a. a housing adapted to be mounted about said flow line; b. a flow blocking means mounted in said housing for movement toward said flow line; c. moving means for moving said flow blocking means into engagement with said flow line; and d. said flow blocking means including a cutting head with means for rotating same for cutting into the flow line as the said moving means moves said cutting head into engagement with said flow line and a conical section having a generally conical shape whereby, as said moving means causes said conical section to engage said flow line, said flow line is sheared into two portions such that said flow line is deformed to prevent flow therethrough.
Claim 4
Independent Claim
132 words
An apparatus for controlling the flow of fluid through a flow line comprising: a. a housing adapted to be mounted about said flow line; b. a flow blocking means mounted in said housing for movement toward said flow line; c. moving means for moving said flow blocking means into engagement with said flow line; and d. said flow blocking means including a cutting head with means for rotating same for cutting into the flow line as the said moving means moves said cutting head into engagement with said flow line and a conical section having a generally conical shape whereby, as said moving means causes said conical section to engage said flow line, said flow line is sheared into two portions such that said flow line is deformed to prevent flow therethrough.
Claim 5
Dependent Claim
27 words
The apparatus set forth in claim 1 including: a. said rotating means is a hydraulic motor which may be actuated from a point remote from said apparatus.
Claim 6
Dependent Claim
102 words
The apparatus set forth in claim 1 including: a. said housing having a first section with a sealed end disposed on one side of said flow line; b. said blocking means being slidably mounted in said first section between said sealed end and said flow line; and c. sealing means mounted on said blocking means for sealing against the passage of fluid between said blocking means and said first housing section such that an expandable chamber is formed in said housing whereby fluid entering said expandable chamber under pressure causes said blocking means to be moved into engagement with said flow line.
Claim 7
Dependent Claim
128 words
The apparatus set forth in claim 1 including: a. said housing having a first section disposed on one side of said flow line and a second section disposed on the other side of said flow line in substantial alignment with said first housing section; b. said blocking means being mounted in said first housing section for movement toward both said flow line and said second housing section; c. said moving means for moving said blocking means into engagement with said flow line also moving said blocking means into said second housing section on the other side of said flow line; and d. said second section including a receiving means for receiving and securing said blocking means against further movement after flow through said flow line has been blocked.
