Abstract
Abstract An assembly for effecting chemical reactions in solutions by radiation comprises a means providing a source of radiation and a reaction vessel rotatably mounted therearound. The reaction vessel is used to contain the solution to be treated by radiation. The vessel includes a bulge portion which extends radially outwardly for holding the solution at a location for exposure to the radiation. When a precipitate is formed upon exposure to the radiation during the rotation of the vessel, the precipitate is maintained at the furthermost point from the radiation source in the bulge portion so that clear solution will be maintained near the source of radiation. Several specific embodiments of the assembly are disclosed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
156 words
An assembly for effecting chemical reactions in solutions by radiation comprising: a. means providing a source of radiation, and b. a vessel rotatably mounted around said source of radiation for containing a solution to be treated by radiation, c. said vessel includes a reaction chamber, a collecting chamber spaced vertically below the reaction chamber and a wall portion extending therebetween, d. said reaction chamber including a bulge portion which extends radially outwardly for holding solution adjacent the radiation source while the vessel is rotating and precipitate is being formed, e. said bulge portion having sufficient depth with respect to the radiation source so that the precipitate is maintained at the furthermost point from the radiation source and the clear solution is maintained near the source of radiation, f. said wall portion being effective to allow passage of material between the bulge portion and the collecting chamber, g. and means for rotating said vessel around said source.
Claim 2
Dependent Claim
156 words
An assembly for effecting chemical reactions in solutions by radiation comprising: a. means providing a source of radiation, and b. a vessel rotatably mounted around said source of radiation for containing a solution to be treated by radiation, c. said vessel includes a reaction chamber, a collecting chamber spaced vertically below the reaction chamber and a wall portion extending therebetween, d. said reaction chamber including a bulge portion which extends radially outwardly for holding solution adjacent the radiation source while the vessel is rotating and precipitate is being formed, e. said bulge portion having sufficient depth with respect to the radiation source so that the precipitate is maintained at the furthermost point from the radiation source and the clear solution is maintained near the source of radiation, f. said wall portion being effective to allow passage of material between the bulge portion and the collecting chamber, g. and means for rotating said vessel around said source.
Claim 3
Dependent Claim
24 words
An assembly as defined in claim 1 wherein the bulge portion is annular and has a cross-sectional shape of a trough or triangular form.
Claim 4
Dependent Claim
67 words
An assembly as defined in claim 1 wherein the vessel includes an annular light protective disk disposed between the reaction chamber and the collecting chamber, said annular light protective disk being spaced from the inside of the wall portion of the vessel to leave an annular gap therebetween for the passage of material including solution, precipitate and mixtures thereof between the reaction chamber and the collecting chamber.
Claim 5
Dependent Claim
30 words
An assembly as defined in claim 3 wherein the walls of the collecting chamber portion have a structural configuration that is impervious to light below the annular light protection disk.
Claim 6
Dependent Claim
18 words
An assembly as defined in claim 1 wherein the bulge portion is enclosed by a cooling jacket structure.
Claim 7
Dependent Claim
51 words
An assembly as defined in claim 1 wherein a second bulge portion is being located in the collecting chamber to contain precipitates which begin to move upwardly as the vessel rotates, said second bulge being smaller in cross-section than the first bulge portion which forms a part of the reaction chamber.
Claim 8
Dependent Claim
37 words
An assembly as defined in claim 1 wherein the radiation source comprises a plurality of light sources disposed in annular form and at least one metallic reflector is disposed between the source and the solution being treated.
Claim 9
Dependent Claim
18 words
An assembly as defined in claim 1 wherein the radiation source provides electrons, soft x-rays or gamma rays.
Claim 10
Dependent Claim
24 words
An assembly as defined in claim 1 wherein a driving means is located a spaced distance from said vessel to effect rotational movement thereof.
Claim 11
Dependent Claim
34 words
An assembly as defined in claim 1 wherein the vessel includes an upper, central supply inlet and a lower discharge outlet disposed at the bottom thereof to remove collected materials from the collecting chamber.
Claim 12
Dependent Claim
16 words
An assembly as defined in claim 1 wherein a protective hood encloses the rotatably mounted vessel.
Claim 13
Dependent Claim
28 words
An assembly as defined in claim 1 wherein said vessel includes a hood member displaceably mounted over the radiation source to filter the radiation passing to the solution.
Claim 14
Dependent Claim
22 words
An assembly as defined in claim 1 wherein a fluid conducting jacket is disposed between the reaction chamber and the radiation source.
Claim 15
Dependent Claim
147 words
A vessel assembly for effecting chemical reactions in solutions comprising: a. an upper reaction chamber, b. a radiation source, c. a lower collecting chamber, d. a wall portion extending between the upper and lower chambers to allow passage of material including solution, precipitate and mixtures thereof therebetween, and e. means for rotating said chambers with respect to said source, f. said reaction chamber and collecting chamber being formed around a center bore which is effective to contain the radiation source, g. said reaction chamber including a bulge portion which extends radially outwardly for holding solution adjacent the radiation source while the vessel is rotating and precipitate is being formed, h. said bulge portion having sufficient depth with respect to the radiation source so that the precipitate is maintained at the furthermost point from the radiation source and the clear solution is maintained near the source of radiation.
Claim 16
