Claim 5
Dependent Claim 43 words
The combination of claim 1 and wherein said bottom component of said container unit includes a woven sheet material made of synthetic yarn and having a frustoconical configuration, said supporting rings including a lower supporting ring to which said bottom component is fixed.
Claim 6
Dependent Claim 157 words
The combination of claim 1 and wherein said bottom component has a frustoconical configuration and opposed upper and lower ends with said upper end being larger than its lower end, one of said supporting rings being a lower supporting ring to which the larger end of said bottom component is fixed, an inner frusto-conical member surrounded by and spaced from said bottom component to form an annular gap therewith, said inner member having upper and lower ends with said lower end being larger than sAid upper end thereof, and a plurality of radially extending connecting members distributed circumferentially along said gap and fixing said frusto-conical members to each other, said gap forming an annular outlet, a tapered substantially funnel-shaped member fixed to and extending downwardly from the smaller end of said bottom component to receive material flowing through said outlet, and annular valve means situated in the region of said outlet for closing and opening the same.
Claim 7
Dependent Claim 42 words
The combination of claim 1 and wherein said top component of said container unit is formed with a central filling opening, and a ring clamped to said top component at said filling opening thereof, said ring being carried by said outer framework.
Claim 8
Dependent Claim 172 words
In a silo construction, an outer framework, at least a pair of supporting rings carried by said outer framework, a container unit having top and bottom components and a cylindrical wall component extending therebetween, said unit being composed at least in part of a foldable sheet material, and clamping means clamping said unit to said rings, said cylindrical wall component of said unit being composed of said foldable sheet material and having an upper end folded back upon itself to form an annular loop at the upper end of said cylindrical wall component, an elongated elastic body of foldable material situated in the interior of said loop to form an annular yieldable bulging portion at the upper end of said cylindrical wall component, said clamping means including a clamping ring clamping said upper end of said cylindrical wall component to an upper one of said supporting rings, the latter ring forming with said clamping ring a groove which receives said annular bulging portion at the upper end of said cylindrical wall component.
Claim 9
Dependent Claim 172 words
In a silo construction, an outer framework, at least a pair of supporting rings carried by said outer framework, a container unit having top and bottom components and a cylindrical wall component extending therebetween, said unit being composed at least in part of a foldable sheet material, and clamping means clamping said unit to said rings, said cylindrical wall component of said unit being composed of said foldable sheet material and having an upper end folded back upon itself to form an annular loop at the upper end of said cylindrical wall component, an elongated elastic body of foldable material situated in the interior of said loop to form an annular yieldable bulging portion at the upper end of said cylindrical wall component, said clamping means including a clamping ring clamping said upper end of said cylindrical wall component to an upper one of said supporting rings, the latter ring forming with said clamping ring a groove which receives said annular bulging portion at the upper end of said cylindrical wall component.
Claim 10
Dependent Claim 110 words
In a silo construction, an outer framework, at least a pair of supporting rings carried by said outer framework, a container unit having top and bottom components and a cylindrical wall component extending therebetween, said unit being composed at least in part of a foldable sheet material, and clamping means clamping said unit to said rings, said supporting rings including a lower supporting ring situated adjacent a lower end of said cylindrical wall component of said unit, said clamping means including a clamping ring clamping said lower end of said cylindrical wall component to said lower supporting ring, and means operatively connected with said clamping ring for shifting the latter.
Claim 11
Dependent Claim 110 words
In a silo construction, an outer framework, at least a pair of supporting rings carried by said outer framework, a container unit having top and bottom components and a cylindrical wall component extending therebetween, said unit being composed at least in part of a foldable sheet material, and clamping means clamping said unit to said rings, said supporting rings including a lower supporting ring situated adjacent a lower end of said cylindrical wall component of said unit, said clamping means including a clamping ring clamping said lower end of said cylindrical wall component to said lower supporting ring, and means operatively connected with said clamping ring for shifting the latter.
Claim 12
Dependent Claim 89 words
