Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
63 words
An agitator for a cylindrical vessel comprising agitating members arranged along and projecting outwardly from a shaft and comprising baffle means for baffling flow of liquid material along and immediately around the shaft, portions of agitating members which extend the greatest distance from the shaft extending a greater distance from the shaft than the portion of the baffle means farthest from the shaft.
Claim 2
Dependent Claim
63 words
An agitator for a cylindrical vessel comprising agitating members arranged along and projecting outwardly from a shaft and comprising baffle means for baffling flow of liquid material along and immediately around the shaft, portions of agitating members which extend the greatest distance from the shaft extending a greater distance from the shaft than the portion of the baffle means farthest from the shaft.
Claim 3
Dependent Claim
34 words
An agitator according to claim 1, in which the baffle means are in the form of discs and at least one portion of each agitating member projects outwardly beyond the periphery of the Discs.
Claim 4
Dependent Claim
18 words
An agitator according to claim 1 in which the baffle means are fixed in relation to the shaft.
Claim 5
Dependent Claim
19 words
An agitator according to claim 1 in which the baffle means are freely mounted in relation to the shaft.
Claim 6
Dependent Claim
26 words
An agitator according to claim 2 in which the discs have bosses so that in the axial direction they occupy the distance between adjacent agitator members.
Claim 7
Dependent Claim
30 words
An agitator according to claim 1 in which the agitating members are in the form of arms and adjacent arms extend from the shaft at an angle to one another.
Claim 8
Dependent Claim
26 words
An agitator according to claim 1 in which the agitator members are in the form of arms and they are attached substantially tangentially to the shaft.
Claim 9
Dependent Claim
30 words
An agitator member according to claim 1, in which the agitator members are in the form of eccentrically disposed rings with adjacent rings extending in different directions from the shaft.
Claim 10
Dependent Claim
100 words
Agitating equipment which comprises a vessel adapted to retain a liquid, and an inlet opening at the bottom of the vessel, the vessel containing a mass of grinding elements and a vertical shaft with agitating members arranged along the shaft and projecting from the shaft with the portions thereof farthest from the shaft spaced from the inner surface of the vessel, and means arranged along the shaft and projecting from it a lesser distance than the agitating members to baffle the flow of liquid along and immediately around the shaft when the shaft is rotated while the vessel contains liquid.
Claim 11
Dependent Claim
100 words
Agitating equipment which comprises a vessel adapted to retain a liquid, and an inlet opening at the bottom of the vessel, the vessel containing a mass of grinding elements and a vertical shaft with agitating members arranged along the shaft and projecting from the shaft with the portions thereof farthest from the shaft spaced from the inner surface of the vessel, and means arranged along the shaft and projecting from it a lesser distance than the agitating members to baffle the flow of liquid along and immediately around the shaft when the shaft is rotated while the vessel contains liquid.
Claim 12
Dependent Claim
24 words
The equipment of claim 9 in which the agitating members are arms and the ends of each arm extend different distances from the shaft.
Claim 13
Dependent Claim
15 words
The equipment of claim 10 in which each arm is substantially tangential to the shaft.
Claim 14
Dependent Claim
19 words
The equipment of claim 10 in which adjacent arms extend from the shaft at an angle to one another.
Claim 15
Dependent Claim
13 words
The equipment of claim 9 in which each baffle means is a disc.
Claim 16
Dependent Claim
23 words
The equipment of claim 13 in which at least a portion of each agitating member projects outwardly beyond the periphery of the discs.
Claim 17
Dependent Claim
22 words
The equipment of claim 13 in which the disc is attached to the shaft so as to be freely rotatable about it.
Claim 18
Dependent Claim
37 words
The equipment of claim 13 in which each disc is attached to the shaft by a boss, the disc and boss are situated immediately between two arms, and said two arms are at 90* to one another.
Claim 19
Dependent Claim
28 words
The equipment of claim 9 in which the agitating members are in the form of eccentrically disposed rings with adjacent rings extending in different directions from the shaft.
