Abstract
Abstract An inerting chamber and enclosure or access member are formed such that the escutcheon plate or outer member of the closure is hinged and the same hinges may be utilized to both swing the escutcheon plate out for cleaning and servicing of the chamber and also if the fastening devices for the access plate are loosened may be utilized to swing the entire inerting chamber and access plate out of the way for servicing of the electron beam unit.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
150 words
Apparatus for electron beam curing comprising a source of high energy electrons, an outer plate-like escutcheon member and apertured access member adopted to join said escutcheon member wherein (a) at least one of said members is formed with a concave area such that when said members are joined, a slotlike opening is formed; (b) adjustable positioning means are provided to position said escutcheon member in contact or removed from said access member; (c) there are provided releasable means to secure said access member such that said source of high energy electrons is directed through the aperture; (d) releasable means are provided to secure said escutcheon member to said access member; and (e) said positioning means are adapted to simultaneously remove both said access member and said escutcheon member when they are secured together and said releasable means securing said access member to said source of high energy electrons is released.
Claim 2
Dependent Claim
150 words
Apparatus for electron beam curing comprising a source of high energy electrons, an outer plate-like escutcheon member and apertured access member adopted to join said escutcheon member wherein (a) at least one of said members is formed with a concave area such that when said members are joined, a slotlike opening is formed; (b) adjustable positioning means are provided to position said escutcheon member in contact or removed from said access member; (c) there are provided releasable means to secure said access member such that said source of high energy electrons is directed through the aperture; (d) releasable means are provided to secure said escutcheon member to said access member; and (e) said positioning means are adapted to simultaneously remove both said access member and said escutcheon member when they are secured together and said releasable means securing said access member to said source of high energy electrons is released.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1, wherein said slotlike opening is of less cross-section at the entrance and exit than at the area of said aperture.
Claim 4
Dependent Claim
16 words
The apparatus of claim 1, further comprising means for supplying inert gas to said slotlike opening.
Claim 5
Dependent Claim
13 words
The apparatus of claim 1, wherein said escutcheon member further comprises cooling means.
Claim 6
Dependent Claim
29 words
The apparatus of claim 1, wherein said apertured access panel has an opening the shape of which generally corresponds to the shape of the source of high energy electrons.
Claim 7
Dependent Claim
20 words
The apparatus of claim 1, wherein removal of said access panel allows servicing and withdrawal of the electron beam device.
Claim 8
Dependent Claim
22 words
The apparatus of claim 1, wherein each member has a concave portion which, when placed in mating position, form an inerting chamber.
Claim 9
Dependent Claim
29 words
The apparatus of claim 1, wherein the entrance and exit to the slot are provided with adjustable devices to increase or decrease the area of the entrance and exit.
Claim 10
Dependent Claim
55 words
Apparatus for high energy electron beam treatment comprising a housing for a source of high energy electrons, access means for gaining access to said housing, said access means comprising an interior plate and an escutcheon plate, a passage provided between said interior plate and said escutcheon plate for passage of material through said access means.
Claim 11
Dependent Claim
55 words
Apparatus for high energy electron beam treatment comprising a housing for a source of high energy electrons, access means for gaining access to said housing, said access means comprising an interior plate and an escutcheon plate, a passage provided between said interior plate and said escutcheon plate for passage of material through said access means.
Claim 12
Dependent Claim
36 words
The apparatus of claim 9, wherein at least one of said interior plate and escutcheon plate is provided with a concave portion to form said passage when joined with the matching escutcheon plate or interior plate.
Claim 13
Dependent Claim
15 words
The apparatus of claim 9, further comprising means for supplying inert gas to said passage.
Claim 14
Dependent Claim
19 words
The apparatus of claim 9, further comprising means for partially blocking the entrance and the exit of said passage.
Claim 15
Dependent Claim
14 words
The apparatus of claim 9, wherein positioning means are attached to said escutcheon plate.
Claim 16
Dependent Claim
16 words
The apparatus of claim 13, wherein said escutcheon member is releasably attached to said interior plate.
Claim 17
Dependent Claim
28 words
The apparatus of claim 13, wherein said positioning means is adapted to position both the escutcheon plate and said interior plate at a position removed from said housing.
Claim 18
Dependent Claim
26 words
The apparatus of claim 14, wherein said positioning means is adapted to position the escutcheon plate at a removed position from said interior plate for service.
Claim 19
Dependent Claim
21 words
The apparatus of claim 11, further comprising a fitting and lead to permit detection of inert gas concentration in said passage.
Claim 20
Dependent Claim
14 words
The apparatus of claim 9, further comprising cooling means located in said escutcheon plate.
