Abstract

An actuation tool includes a mandrel; at least one protrusion in the mandrel representing a deformation of the material of the mandrel resulting in the mandrel having a lesser axial dimension than it does with the protrusion removed or diminished; and a fluid inlet positioned to facilitate application of pressure to one of an inside or outside surface of the mandrel and method.

Claims

exact text as granted — not AI-modified
1 . An actuation tool comprising:
 a mandrel;   at least one protrusion in the mandrel representing a deformation of the material of the mandrel resulting in the mandrel having a lesser axial dimension than it does with the protrusion removed or diminished; and   a fluid inlet positioned to facilitate application of pressure to one of an inside or outside surface of the mandrel.   
   
   
       2 . The actuation tool as claimed in  claim 1  wherein the at least one protrusion is a plurality of protrusions. 
   
   
       3 . The actuation tool as claimed in  claim 2  wherein each of the plurality of protrusions is of different dimensions than any other protrusion. 
   
   
       4 . The actuation tool as claimed in  claim 2  wherein the plurality of protrusions include at least one protrusion having different material thickness than at least one other protrusion. 
   
   
       5 . The actuation tool as claimed in  claim 1  wherein the at least one protrusion is substantially straightenable upon application of pressure through the fluid inlet. 
   
   
       6 . The actuation tool as claimed in  claim 2  wherein the plurality of protrusions include at least one protrusion having different dimensions than at least one other protrusion. 
   
   
       7 . The actuation tool as claimed in  claim 6  wherein the plurality of protrusions include at least one protrusion having different material thickness than at least one other protrusion. 
   
   
       8 . A method for applying a linear force comprising:
 applying pressure to the tool of  claim 1 ;   undeforming the at least one protrusion; and   causing extension of the mandrel due to the undeforming.   
   
   
       9 . The method for applying a linear force as claimed in  claim 8  wherein the applying is directed to an inside dimension of the mandrel. 
   
   
       10 . The method for applying a linear force as claimed in  claim 8  wherein the undeforming of the at least one protrusion is undeforming of a number of protrusions. 
   
   
       11 . The method for applying a linear force as claimed in  claim 10  wherein the protrusions are sequentially undeformed. 
   
   
       12 . The method for applying a linear force as claimed in  claim 11  wherein the sequence is one or more at a time and one or more at another time. 
   
   
       13 . The method for applying a linear force as claimed in  claim 8  wherein the method further comprises connecting the tool to an actuatable device. 
   
   
       14 . The method for applying a linear force as claimed in  claim 8  wherein the method further comprises actuating the actuatable device.
