Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
An apparatus for fabricating blocks, especially block anodes, from compacted granular material or the like, comprising means providing an air-tight enclosed compaction compartment equipped with a removable cover having sealing means therein, a charging mechanism for introducing material to be compacted into said compaction compartment, said compaction compartment defining an internal space for receiving the material, at least one material compacting mechanism mounted within said internal space of said compaction compartment, said material compacting mechanism comprising at least one vibration mechanism located within said internal space of said compaction compartment, vacuum means communicating with said internal space of said compaction compartment for creating vacuum conditions therein in order to remove any gases while reducing the pressUre in the material compaction compartment during the material compacting operation.
Claim 2
Independent Claim
126 words
An apparatus for fabricating blocks, especially block anodes, from compacted granular material or the like, comprising means providing an air-tight enclosed compaction compartment equipped with a removable cover having sealing means therein, a charging mechanism for introducing material to be compacted into said compaction compartment, said compaction compartment defining an internal space for receiving the material, at least one material compacting mechanism mounted within said internal space of said compaction compartment, said material compacting mechanism comprising at least one vibration mechanism located within said internal space of said compaction compartment, vacuum means communicating with said internal space of said compaction compartment for creating vacuum conditions therein in order to remove any gases while reducing the pressUre in the material compaction compartment during the material compacting operation.
Claim 3
Dependent Claim
58 words
The apparatus as defined in claim 1, wherein said means defining said material compaction compartment further includes a bottom member, said material compacting mechanism within said compaction compartment comprising at least one additional vibration mechanism, one of said vibration mechanisms being supported at said bottom member whereas the other of said vibration mechanisms being mounted at said cover.
Claim 4
Dependent Claim
31 words
The apparatus as defined in claim 1, further including a cylinder-piston drive operably coupled with said material compacting mechanism for selectively subjecting the material introduced into said compaction compartment to pressure.
Claim 5
Dependent Claim
45 words
The apparatus as defined in claim 1, wherein said means defining said compaction compartment includes a bottom member having inclined portions, said bottom member serving to seal off said compaction compartment at its lower end, and means for selectively raising and lowering said bottom member.
Claim 6
Dependent Claim
22 words
The apparatus as defined in claim 4, wherein said means for selectively raising and lowering said bottom member comprises a cylinder-piston drive.
Claim 7
Dependent Claim
26 words
The apparatus as defined in claim 1, further including a machine frame, drive means supported at said machine frame for raising and lowering said removable cover.
Claim 8
Dependent Claim
16 words
The apparatus as defined in claim 6, wherein said drive means comprises a cylinder-piston drive arrangement.
Claim 9
Dependent Claim
45 words
The apparatus as defined in claim 6, further including a rigid support member for said machine frame, and resilient means for supporting said machine frame at said rigid support member and for dampening the transmission of vibrations between said machine frame and rigid support member.
Claim 10
Dependent Claim
31 words
The apparatus as defined in claim 2, further including resilient means cooperating with each of said vibration mechanisms for dampening the transmission of vibrations to said means providing said compaction compartment.
