Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A remotely actuated wellbore tool stop comprising: a housing which includes a primary bore; a motor in said housing; a shaft operatively connected to said motor; a stop pivotably connected to said shaft wherein said stop blocks said primary bore when said motor actuates said shaft in a first direction and said stop is removed from blocking said primary bore when said motor actuates said shaft in a second direction; and an electronic controller communicating with said motor for actuating said motor.
Claim 2
Dependent Claim
82 words
A remotely actuated wellbore tool stop comprising: a housing which includes a primary bore; a motor in said housing; a shaft operatively connected to said motor; a stop pivotably connected to said shaft wherein said stop blocks said primary bore when said motor actuates said shaft in a first direction and said stop is removed from blocking said primary bore when said motor actuates said shaft in a second direction; and an electronic controller communicating with said motor for actuating said motor.
Claim 3
Dependent Claim
44 words
A remotely actuated tool stop comprising: a) a housing having at least a primary bore; b) a tool stop mounted in said housing; c) a controller communicating with said tool stop to selectively direct said tool stop to block and unblock said primary bore.
Claim 4
Dependent Claim
44 words
A remotely actuated tool stop comprising: a) a housing having at least a primary bore; b) a tool stop mounted in said housing; c) a controller communicating with said tool stop to selectively direct said tool stop to block and unblock said primary bore.
