Abstract
Abstract A method of controlling the cutting of an object comprising pressurizing a fluid; forming from said pressurized fluid a fluid jet adapted to cut the object; directing the said object-cutting jet towards the object and, when it is not desired to cut the object, preventing the object-cutting jet from reaching the object while maintaining the pressurization of the fluid.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid, passing said pressurized first fluid through a nozzle to form a fluid jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, introducing into said nozzle a further fluid which prevents the formation of a jet capable of cutting the object, the introduction of the further fluid into the nozzle being effected while maintaining the pressurization of the first fluid.
Claim 2
Independent Claim
87 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid, passing said pressurized first fluid through a nozzle to form a fluid jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, introducing into said nozzle a further fluid which prevents the formation of a jet capable of cutting the object, the introduction of the further fluid into the nozzle being effected while maintaining the pressurization of the first fluid.
Claim 3
Independent Claim
84 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid; forming from said pressurized first fluid, a fluid jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, introducing a second fluid into the object-cutting jet so as to disperse the latter before it reaches the object, the introduction of the second fluid into the object-cutting jet being effected while maintaining the pressurization of the first fluid.
Claim 4
Independent Claim
84 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid; forming from said pressurized first fluid, a fluid jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, introducing a second fluid into the object-cutting jet so as to disperse the latter before it reaches the object, the introduction of the second fluid into the object-cutting jet being effected while maintaining the pressurization of the first fluid.
Claim 5
Independent Claim
70 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid; forming from said pressurized first fluid, a jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, directing a second fluid onto the object-cutting jet so as to deflect the latter away from the object while maintaining the pressurization of the first fluid.
Claim 6
Independent Claim
70 words
A method of controlling the cutting of an object comprising: pressurizing a first fluid; forming from said pressurized first fluid, a jet adapted to cut the object; directing said object-cutting jet towards the object and, when it is not desired to cut the object, directing a second fluid onto the object-cutting jet so as to deflect the latter away from the object while maintaining the pressurization of the first fluid.
Claim 7
Dependent Claim
88 words
Apparatus for controlling the cutting of an object comprising: means for pressurizing a first fluid so as to form therefrom a fluid jet adapted to cut an object; means for supporting the object in a position in which it may be cut by the object-cutting jet; means for directing the object-cutting jet towards said position; and means, operable when desired, for introducing a second fluid into the object-cutting jet so as to disperse the latter and impair its object-cutting properties while maintaining the pressurization of the first fluid.
Claim 8
Dependent Claim
88 words
Apparatus for controlling the cutting of an object comprising: means for pressurizing a first fluid so as to form therefrom a fluid jet adapted to cut an object; means for supporting the object in a position in which it may be cut by the object-cutting jet; means for directing the object-cutting jet towards said position; and means, operable when desired, for introducing a second fluid into the object-cutting jet so as to disperse the latter and impair its object-cutting properties while maintaining the pressurization of the first fluid.
Claim 9
Dependent Claim
88 words
Apparatus for controlling the cutting of an object comprising; means for pressurizing a first fluid so as to form therefrom a fluid jet adapted to cut an object; means for supporting the object in a position in which it may be cut by the object-cutting jet; means for directing the object-cutting jet towards said position, and means, operable when desired, for directing a second fluid against the object-cutting jet so as to deflect the latter and impair its object-cutting properties while maintaining the pressurization of the first fluid.
Claim 10
Dependent Claim
88 words
Apparatus for controlling the cutting of an object comprising; means for pressurizing a first fluid so as to form therefrom a fluid jet adapted to cut an object; means for supporting the object in a position in which it may be cut by the object-cutting jet; means for directing the object-cutting jet towards said position, and means, operable when desired, for directing a second fluid against the object-cutting jet so as to deflect the latter and impair its object-cutting properties while maintaining the pressurization of the first fluid.
