Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
109 words
In a method of mixing a soil stabilizing material in solid or liquid form into a soil course by means of a carrier transportable over the surface of soil and having a plurality of material injecting members, said method comprising the step of moving the plurality of material injecting members through the soil course in a closed path relative to the carrier while the carrier is being transported over the surface of the soil, the improvement wherein the closed path is in the shape of two half circles connected by two substantially straight portions which are tangential to the half circles, said half circles having the least possible radius.
Claim 2
Dependent Claim
109 words
In a method of mixing a soil stabilizing material in solid or liquid form into a soil course by means of a carrier transportable over the surface of soil and having a plurality of material injecting members, said method comprising the step of moving the plurality of material injecting members through the soil course in a closed path relative to the carrier while the carrier is being transported over the surface of the soil, the improvement wherein the closed path is in the shape of two half circles connected by two substantially straight portions which are tangential to the half circles, said half circles having the least possible radius.
Claim 3
Dependent Claim
23 words
A method as claimed in claim 1 wherein the material injecting members are moved at a substantially constant speed around the closed path.
Claim 4
Dependent Claim
30 words
A method as claimed in claim 1 wherein the soil stabilizing material is injected into the soil course by the material injecting members throughout the closed path which they travel.
Claim 5
Dependent Claim
38 words
A method as claimed in claim 1 wherein the soil stabilizing material is not injected into the soil course by the material injecting members while they are moving on one of the straight portions of the closed path.
Claim 6
Dependent Claim
27 words
A method as claimed in claim 1 wherein the soil stabilizing material is injected into the soil course by the material injecting members at a constant rate.
Claim 7
Dependent Claim
28 words
A method as claimed in claim 1 wherein the two substantially straight portions of the closed path are substantially perpendicular to the direction of motion of the carrier.
Claim 8
Dependent Claim
32 words
A method as claimed in claim 1 wherein the amount of soil stabilizing material injected into the soil course by the material injecting members varies at different depths in the soil course.
Claim 9
Dependent Claim
128 words
In a method of mixing a soil stabilizing material in solid or liquid form into a soil course by means of a carrier transportable over the surface of the soil and having a plurality of material injecting members, said method comprising the step of moving the plurality of material injecting members through the soil course in a closed path relative to the carrier while the carrier is being transported over the surface of the soil, the improvement wherein the closed path includes at least one substantially straight portion which is not substantially parallel to the direction of motion of the carrier and the soil stabilizing material is injected into the soil course while the material injecting members are moving along said substantially straight portion of the closed path.
Claim 10
Dependent Claim
128 words
In a method of mixing a soil stabilizing material in solid or liquid form into a soil course by means of a carrier transportable over the surface of the soil and having a plurality of material injecting members, said method comprising the step of moving the plurality of material injecting members through the soil course in a closed path relative to the carrier while the carrier is being transported over the surface of the soil, the improvement wherein the closed path includes at least one substantially straight portion which is not substantially parallel to the direction of motion of the carrier and the soil stabilizing material is injected into the soil course while the material injecting members are moving along said substantially straight portion of the closed path.
Claim 11
Dependent Claim
23 words
A method as claimed in claim 8 wherein said substantially straight portion is substantially perpendicular to the direction of motion of the carrier.
Claim 12
Dependent Claim
23 words
A method as claimed in claim 8 wherein the material injecting members are moved at a substantially constant speed around the closed path.
Claim 13
Dependent Claim
30 words
A method as claimed in claim 8 wherein the soil stabilizing material is injected into the soil course by the material injecting members throughout the closed path which they travel.
Claim 14
Dependent Claim
36 words
A method as claimed in claim 8 wherein the soil stabilizing material is injected into the soil course substantially only while the material injecting members are moving along said substantially straight portion of the closed path.
Claim 15
Dependent Claim
32 words
A method as claimed in claim 8 wherein the amount of soil stabilizing material injected into the soil course by the material injecting members varies at different depths in the soil course.
Claim 16
Independent Claim
101 words
A method of mixing into a ground layer a ground stabilizing material in solid or liquid form, whereat a number of material injecting members are caused to move in an endless path on a mobile vehicle so that a substantial part of the material discharge from the members takes place at their movement in a substantially linear portion of the path across the direction of vehicle movement, characterized in that the material is agitated while passing through the material injecting members and is proportioned variably on being discharged, so that a predetermined amount per time unit leave the material injecting members.
Claim 17
Independent Claim
101 words
A method of mixing into a ground layer a ground stabilizing material in solid or liquid form, whereat a number of material injecting members are caused to move in an endless path on a mobile vehicle so that a substantial part of the material discharge from the members takes place at their movement in a substantially linear portion of the path across the direction of vehicle movement, characterized in that the material is agitated while passing through the material injecting members and is proportioned variably on being discharged, so that a predetermined amount per time unit leave the material injecting members.
Claim 18
Dependent Claim
22 words
A method as claimed in claim 14, characterized in that the material is continuously agitated while passing through the material injecting members.
Claim 19
Dependent Claim
37 words
A method as claimed in claim 14, characterized in that the agitator and/or discharge means in the material injection members rotates with a speed depending on the travelling speed of the material injecting members along their path.
Claim 20
Dependent Claim
26 words
A method as claimed in claim 16, characterized in that the rotational speed is varied in response to the travelling speed of the material injecting members.
Claim 21
Dependent Claim
31 words
A method as claimed in claim 14, characterized in that material is supplied to the material injecting means substantially only during their movement in a curved portion of the endless path.
Claim 22
Dependent Claim
23 words
A method as claimed in claim 14, characterized in that the material is discharged into the ground in two or more vertical layers.
