Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
An apparatus for mixing into a ground layer a ground stabilizing material in solid or liquid form, said apparatus comprising: a carrier, means for moving said carrier in an endless path above the ground surface, said carrier including a number of material injecting members, a storage container carrying ground stabilizing material, means for transferring said material from said storage container to said material injecting members, the improvement wherein: said means for moving said carrier in an endless path above the ground surface comprises means for moving said material injecting members in a substantially linear portion of the endless path across the travelling direction of the vehicle, means for agitating the material injecting members during its passage, and means for variably proportioning material at its departure from the material injecting members.
Claim 2
Independent Claim
130 words
An apparatus for mixing into a ground layer a ground stabilizing material in solid or liquid form, said apparatus comprising: a carrier, means for moving said carrier in an endless path above the ground surface, said carrier including a number of material injecting members, a storage container carrying ground stabilizing material, means for transferring said material from said storage container to said material injecting members, the improvement wherein: said means for moving said carrier in an endless path above the ground surface comprises means for moving said material injecting members in a substantially linear portion of the endless path across the travelling direction of the vehicle, means for agitating the material injecting members during its passage, and means for variably proportioning material at its departure from the material injecting members.
Claim 3
Dependent Claim
33 words
An apparatus as claimed in claim 1, characterized in that at least one agitating and one proportioning means are mounted on a rotatable vertical shaft (11, 11a) in the material injecting members (5).
Claim 4
Dependent Claim
18 words
An apparatus as claimed in claim 2, wherein the proportioning means comprises a propeller-like element with adjustable pitch.
Claim 5
Dependent Claim
49 words
An apparatus as claimed in claim 1, characterized in that the vertical shaft is caused to rotate via a preferably circular element at the upper end of the material injecting members, the element engaging against and rolling against a track along the travelling path of the material injecting members.
Claim 6
Dependent Claim
26 words
An apparatus as claimed in claim 4, characterized in that the relative distance between the element and the track is adjustable for varying the rotational speed.
Claim 7
Dependent Claim
21 words
An apparatus as claimed in claim 4, characterized in that the element consists of an inflatable rubber wheel at variable pressure.
Claim 8
Dependent Claim
27 words
An apparatus as claimed in claim 4, wherein the element is mounted on a rotatable hopper-shaped filling portion in the upper end of the material injecting member.
Claim 9
Dependent Claim
27 words
An apparatus as claimed in claim 1, wherein the material injecting members have a lower administrating member with at least two vertical slots of adjustable aperture size.
Claim 10
Dependent Claim
95 words
An apparatus as claimed in claim 1, wherein a rotatable disk is provided in the region of the curved portion of the track between the storage container and the upper portion of the material injecting members, said disk having a number of holes falling into alignment with the upper portion of the material injecting members, said holes having a diameter corresponding to the inside diameter of said upper portions, and means for driving said disks at a speed such that the centers of the holes move together with the centers of the material injecting members.
