Abstract
Abstract An apparatus for irradiating a flowing material with an electron beam includes an electron beam accelerating device having an electron beam emitter; an irradiation device having an inclined irradiation tray arranged underneath the electron beam emitter and determining a flowpath for the material to be irradiated; and a material feeding arrangement for introducing the material onto the inclined irradiation tray. The material feeding arrangement comprises a riser vessel having an upper portion, a bottom portion and an overflow edge situated at the upper portion and adjoining the irradiation tray upstream thereof as viewed in the direction of material flow and at least one diffuser communicating with the bottom portion of the riser vessel for introducing the material thereinto.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
In an apparatus for irradiating a flowing material with an electron beam, including an electron beam accelerating device having an electron beam emitter; an irradiation device having an inclined irradiation tray arranged underneath the electron beam emitter and determining a flowpath for the material to be irradiated; and material feeding means for introducing the material onto the inclined irradiation tray; the improvement in said material feeding means comprising (a) a riser vessel having an upper portion, a bottom portion and an overflow edge situated at said upper portion and adjoining said irradiation tray upstream thereof as viewed in the direction of material flow; and (b) at least one diffuser communicating with said bottom portion of said riser vessel for introducing the material thereinto.
Claim 2
Dependent Claim
123 words
In an apparatus for irradiating a flowing material with an electron beam, including an electron beam accelerating device having an electron beam emitter; an irradiation device having an inclined irradiation tray arranged underneath the electron beam emitter and determining a flowpath for the material to be irradiated; and material feeding means for introducing the material onto the inclined irradiation tray; the improvement in said material feeding means comprising (a) a riser vessel having an upper portion, a bottom portion and an overflow edge situated at said upper portion and adjoining said irradiation tray upstream thereof as viewed in the direction of material flow; and (b) at least one diffuser communicating with said bottom portion of said riser vessel for introducing the material thereinto.
Claim 3
Dependent Claim
21 words
An apparatus as defined in claim 1, wherein there are provided three juxtapositioned diffusers each extending perpendicularly to said riser vessel.
Claim 4
Dependent Claim
21 words
An apparatus as defined in claim 1, wherein said irradiation tray, said riser vessel and said diffuser constitute a structural unit.
Claim 5
Dependent Claim
39 words
An apparatus as defined in claim 3, further comprising means for pivotally supporting said structural unit about an axis situated in a zone of irradiation and extending perpendicularly to the flow direction of the material on said irradiation tray.
Claim 6
Dependent Claim
12 words
An apparatus as defined in claim 4, wherein said axis is horizontal.
Claim 7
Dependent Claim
39 words
An apparatus as defined in claim 1, further comprising means for pivotally supporting said irradiation tray about an axis situated in a zone of irradiation and extending perpendicularly to the flow direction of the material on said irradiation tray.
Claim 8
Dependent Claim
12 words
An apparatus as defined in claim 6, wherein said axis is horizontal.
Claim 9
Dependent Claim
23 words
An apparatus as defined in claim 6, further comprising means for measuring the layer thickness of the material flowing on said irradiation tray.
Claim 10
Dependent Claim
25 words
