专利汇可以提供Controlled atmosphere chamber for treating products with ionizing radiation专利检索,专利查询,专利分析的服务。并且Apparatus which permits treatment of products with ionizing radiation in a controlled atmosphere comprises a chamber having inlet and outlet openings for the passage of a product to be treated, a radiation-permeable window in one surface, and at least one gas reservoir within the chamber separated by a foraminous panel. Gas is introduced into the reservoir, passes through the foraminous panel and over and around the path of travel of the workpiece to be treated.,下面是Controlled atmosphere chamber for treating products with ionizing radiation专利的具体信息内容。

1. Apparatus for treating products with ionizing radiation in a controlled atmosphere, said apparatus comprising a substantially enclosed chamber having A. spaced outer walls with spaced inlet and outlet openings establishing a path of travel for a workpiece; B. a radiation-permeable window in a surface of said chamber, said window being formed of a material which excludes the passage of gases and being positioned over at least a portion of said path of travel; C. at least one foraminous panel within said chamber defining a reservoir between the panel and an outer wall of the chamber; and D. means for introducing gas into said reservoir and through said foraminous panel into said path of travel.
2. The apparatus of claim 1 in which said inlet and outlet openings are located in outwardly extending sections of said outer walls.
3. The apparatus of claim 1 in which said foraminous panel has substantially uniform openings spaced over its entire surface.
4. The apparatus of claim 1 in which said means for introducing gas comprises a plurality of gas inlet openings into said reservoir.
5. The apparatus of claim 1 in which said radiation-permeable window is a thin metal section.
6. The apparatus of claim 5 in which said metal is aluminum.
7. Apparatus for treating products with ionizing radiation in a controlled atmosphere, said apparatus comprising a substantially enclosed chamber having A. oppositely spaced outer walls with spaced inlet and outlet openings establishing a path of travel for a workpiece; B. a radiation-permeable window in a surface of said chamber, said window being formed of a material which excludes the passage of gases and being positioned over at least a portion of said path of travel; C. oppositely spaced foraminous panels along each side of said path of travel, each of said panels defining a reservoir between the panel and an outer wall of the chamber; and D. means for introducing gas into said reservoirs and through said foraminous panels into said path of travel.
8. The apparatus of claim 7 in which said inlet and outlet openings are located in outwardly extending sections of said outer walls.
9. The apparatus of claim 7 in which said foraminous panels have substantially uniform openings spaced over their entire surfaces.
10. The apparatus of claim 7 in which said means for introducing gas comprises a plurality of gas inlet openings into each of said reservoirs.
11. The apparatus of claim 7 in which said radiation-permeable window is a thin metal section.
12. Apparatus for treating products with ionizing radiation in a controlled atmosphere, said apparatus comprising a substantially enclosed chamber having A. spaced outer walls with spaced inlet and outlet openings establishing a path of travel for a workpiece; B. a radiation-permeable window in a surface of said chamber, said window being formed of a material which excludes the passage of gases and being positioned over at east a portion of said path of travel; C. at least one forAminous panel within said chamber defining a reservoir between the panel and an outer wall of said chamber; D. means for introducing gas into said reservoir and through said foraminous panel into said path of travel; and E. means for passing ionizing radiation through said radiation-permeable window into said path of travel.
13. The apparatus of claim 12 in which said means for passing ionizing radiation is an electron beam accelerator.
14. The apparatus of claim 13 in which said accelerator comprises a radiation-permeable window which is a common window with the radiation-permeable window in said chamber.
15. The apparatus of claim 13 in which said accelerator is an electron linear accelerator operating between about 3 million and about 10 million electron volts.
16. The apparatus of claim 13 in which said accelerator is a DC accelerator operating between about 100,000 and about 4 million electron volts.
