Abstract
Abstract A container having a disc, plate or the like located therein part way between the top and bottom of the container. In this disc there are provided a plurality of conical or similar structures, some extending above and some extending below the disc. These structures act as funnels. Structures extending generally below the device have their larger ends uppermost, and others of the structures that extend above the device have their smaller ends uppermost. Water or other fluid that is to act on the material in the container below the disc enters the wider ends of the dependent funnels or hollow structures to mix with the material under the disc, and the solution rises to exit through the inverted funnels or structures having their smaller ends uppermost.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
A device of the class described comprising a container, said container having top, bottom, and side walls, a partition in the container located intermediate the top and bottom walls thereof, said partition dividing the container into top and bottom portions, the bottom portion being adapted to contain soluble material, at least two pass-through hollow structures located in the partition; at least one pass-through structure having its larger end uppermost, and another pass-through structure having its smaller end uppermost, and a solvent admitting aperture in the upper portion of said container for the reception of the solvent therein above the partition, the solvent passing down through the pass-through structure with its larger end uppermost, and solution provided thereby tending to rise to and through the other pass-through structure which has its smaller end uppermost into the upper part of the container.
Claim 2
Independent Claim
140 words
A device of the class described comprising a container, said container having top, bottom, and side walls, a partition in the container located intermediate the top and bottom walls thereof, said partition dividing the container into top and bottom portions, the bottom portion being adapted to contain soluble material, at least two pass-through hollow structures located in the partition; at least one pass-through structure having its larger end uppermost, and another pass-through structure having its smaller end uppermost, and a solvent admitting aperture in the upper portion of said container for the reception of the solvent therein above the partition, the solvent passing down through the pass-through structure with its larger end uppermost, and solution provided thereby tending to rise to and through the other pass-through structure which has its smaller end uppermost into the upper part of the container.
Claim 3
Dependent Claim
16 words
The device of claim 1 including a plurality of both pass-through structures associated with the partition.
Claim 4
Dependent Claim
16 words
The device of claim 1 wherein said device is adapted to be submerged in the solvent.
Claim 5
Dependent Claim
21 words
The device of claim 1 wherein the pass-through structure with the larger opening at the top depends wholly from the partition.
Claim 6
Dependent Claim
19 words
The device of claim 1 wherein the pass-through structure with the smaller end uppermost extends upwardly from the partition.
Claim 7
Dependent Claim
16 words
The device of claim 1 wherein said pass-through structures are located substantially wholly in the partition.
Claim 8
Dependent Claim
22 words
The device of claim 6 wherein the ends of the pass-through structures are substantially co-planar with the respective surfaces of the partition.
Claim 9
Dependent Claim
11 words
The device of claim 1 wherein the pass-through structures are frusto-conical.
Claim 10
Independent Claim
171 words
A device of the class described comprising a container, the container including top, bottom, and side walls, a partition located intermediate the bottom and top wall, hollow pass-through structures in the partition, said structures having open ends of different sizes, at least one structure having its smaller end uppermost, and another hollow pass-through structure having its larger end uppermost, the partition providing a chamber at the upper portion of the container and a chamber in the lower portion of the container, the latter chamber containing material to be acted upon, wherein an activator therefor enters into the wider end of the hollow structure having its wider end uppermost to impinge upon the contents of the container chamber below the partition, the resultant material being collected in the hollow structure having its narrower end uppermost, passing therethrough into the chamber above the partition, and an opening in the upper chamber for the emission of the material generated by the activator in contact with the material in the lower part of the container.
Claim 11
Independent Claim
171 words
A device of the class described comprising a container, the container including top, bottom, and side walls, a partition located intermediate the bottom and top wall, hollow pass-through structures in the partition, said structures having open ends of different sizes, at least one structure having its smaller end uppermost, and another hollow pass-through structure having its larger end uppermost, the partition providing a chamber at the upper portion of the container and a chamber in the lower portion of the container, the latter chamber containing material to be acted upon, wherein an activator therefor enters into the wider end of the hollow structure having its wider end uppermost to impinge upon the contents of the container chamber below the partition, the resultant material being collected in the hollow structure having its narrower end uppermost, passing therethrough into the chamber above the partition, and an opening in the upper chamber for the emission of the material generated by the activator in contact with the material in the lower part of the container.
Claim 12
Dependent Claim
15 words
The device of claim 9 wherein the hollow structures are located wholly in the partition.
Claim 13
Dependent Claim
20 words
The device of claim 9 wherein the larger ends of both hollow pass-through structures are located closely adjacent the partition.
Claim 14
Dependent Claim
14 words
The device of claim 9 wherein the hollow pass-through structures are frusto-conical in shape.
