Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 159 words
A process for modifying a paper machine headbox manually-adjustable slice rod assembly including a screw jack to permit the assembly to be operated by a fluid actuator in combination with the screw jack and without modifying the structure which supports the assembly, wherein the manually-adjustable slice rod assembly includes a coupler connecting the assembly to a slice lip, the process comprising: (a) cutting the slice rod assembly at two points between the screw jack and the coupler, the two points being located so as not to affect the screw jack and so as not to affect the coupler; (b) removing the section of the slice rod assembly between the two cuts while leaving the screw jack in place coupled to the support structure; (c) inserting a fluid actuator in the position previously occupied by the section of the rod which was removed; and (d) rigidly coupling the fluid actuator to the sections of the rod which were not removed.
Claim 2
Dependent Claim 159 words
A process for modifying a paper machine headbox manually-adjustable slice rod assembly including a screw jack to permit the assembly to be operated by a fluid actuator in combination with the screw jack and without modifying the structure which supports the assembly, wherein the manually-adjustable slice rod assembly includes a coupler connecting the assembly to a slice lip, the process comprising: (a) cutting the slice rod assembly at two points between the screw jack and the coupler, the two points being located so as not to affect the screw jack and so as not to affect the coupler; (b) removing the section of the slice rod assembly between the two cuts while leaving the screw jack in place coupled to the support structure; (c) inserting a fluid actuator in the position previously occupied by the section of the rod which was removed; and (d) rigidly coupling the fluid actuator to the sections of the rod which were not removed.
Claim 3
Dependent Claim 56 words
The process of claim 1 wherein the fluid actuation means includes a rod which is slideable in a sleeve, and the rod is coupled to the slice rod at one location where the slice rod was cut, and the sleeve is coupled to the slice rod at the other location where the slice rod was cut.
Claim 4
Dependent Claim 48 words
The process of claim 1 wherein the fluid actuator includes a rod and sleeve assembly which is coupled to the slice rod and further includes a fluid actuated cylinder and piston assembly coupled to the rod and sleeve assembly to cause the rod to slide within the sleeve.
Claim 5
Dependent Claim 131 words
A process for modifying a paper machine headbox manually-adjustable slice rod assembly including a screw jack, to permit the assembly to be operated by a fluid actuator in combination with the screw jack and without modifying the structure which supports the assembly, wherein the manually-adjustable slice rod assembly includes a coupler connecting the assembly to a slice lip, the process comprising: (a) removing a section of a slice rod assembly between two points on the assembly between the screw jack and the coupler while leaving the screw jack in place coupled to the support structures; (b) inserting a fluid actuator in the position previously occupied by the section of the rod which was removed; and (c) rigidly coupling the fluid actuator to the sections of the rod which were not removed.
Claim 6
Dependent Claim 131 words
A process for modifying a paper machine headbox manually-adjustable slice rod assembly including a screw jack, to permit the assembly to be operated by a fluid actuator in combination with the screw jack and without modifying the structure which supports the assembly, wherein the manually-adjustable slice rod assembly includes a coupler connecting the assembly to a slice lip, the process comprising: (a) removing a section of a slice rod assembly between two points on the assembly between the screw jack and the coupler while leaving the screw jack in place coupled to the support structures; (b) inserting a fluid actuator in the position previously occupied by the section of the rod which was removed; and (c) rigidly coupling the fluid actuator to the sections of the rod which were not removed.
