Abstract
Abstract The door of a horizontally disposed pressure vessel is adjustably supported by a track mounted trolley for reciprocation between door closed and opened positions. The door is provided with apertures for freely receiving trolley mounted pins, which are employed to support an outer end of a material supporting carriage movable from within the pressure vessel as the door is moved towards its opened position. The apertures are sealed by flexible metal bellows. Independent movements of the carriage and door relative to the trolley permit the door to be properly seated in a closed condition under varying carriage loading and/or pressure vessel thermal distortion conditions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A pressure vessel compriSing in combination: a horizontally disposed shell having an end access opening bounded by annular sealing surface means; a door having annular sealing surface means engageable with said shell sealing surface means for closing said access opening and having at least one aperture extending therethrough; a carriage for supporting material to be treated within said shell, said carriage being removably insertable into said shell through said access opening; a trolley supported for horizontal reciprocating movement relative to said access opening; door mounting means and carriage mounting means for independently supporting said door and said carriage on said trolley; said carriage mounting means cantilever supporting said carriage on said trolley and freely extending through said door aperture, whereby upon movement of said trolley, said carriage is removably inserted into said shell as said door is moved between access opening closed and open positions thereof; and sealing means for providing a fluid pressure seal between said door and said carriage mounting means while permitting relative movement therebetween.
Claim 2
Dependent Claim
168 words
A pressure vessel compriSing in combination: a horizontally disposed shell having an end access opening bounded by annular sealing surface means; a door having annular sealing surface means engageable with said shell sealing surface means for closing said access opening and having at least one aperture extending therethrough; a carriage for supporting material to be treated within said shell, said carriage being removably insertable into said shell through said access opening; a trolley supported for horizontal reciprocating movement relative to said access opening; door mounting means and carriage mounting means for independently supporting said door and said carriage on said trolley; said carriage mounting means cantilever supporting said carriage on said trolley and freely extending through said door aperture, whereby upon movement of said trolley, said carriage is removably inserted into said shell as said door is moved between access opening closed and open positions thereof; and sealing means for providing a fluid pressure seal between said door and said carriage mounting means while permitting relative movement therebetween.
Claim 3
Dependent Claim
54 words
A vessel according to claim 1, wherein said door mounting means is adjustable, whereby to permit adjustment of said door relative to said trolley and said carriage mounting means for positioning said door sealing surface means in alignment with said shell sealing surface means when said door is moved into said closed position thereof.
Claim 4
Dependent Claim
169 words
A vessel according to claim 1, wherein said door mounting means includes an upper mounting device for suspending said door from said trolley and a pair of lower mounting devices, said upper mounting device including a pin shaft and slot means and resilient means, said pin shaft having an essentially horizontally disposed axis extending essentially transversely of the path of trolley reciprocation, said slot means being horizontally elongated in a direction parallel to said path and serving to rotatably and slidably support said pin shaft therewithin, said resilient means tends to bias said pin shaft relatively towards one end of said slot means while permitting rotation and sliding movement of said pin shaft relatively towards an opposite end of said slot means, and said lower mounting devices being independently adjustable to effect rotary and/or sliding movements of said pin shaft within said slot means to position said door sealing surface means for alignment with said shell sealing surface means when said door is moved into said closed position thereof.
Claim 5
Dependent Claim
56 words
A vessel according to claim 3, wherein said lower mounting devices each comprise a pair of loosely fitted telescopic sleeve members fixed one to each of said door and trolley, a compression spring disposed within said sleeve members and bearing adjacent opposite ends thereof on said door and said trolley, and means to adjust said spring.
Claim 6
Dependent Claim
113 words
A pressure vessel according to claim 1, wherein said trolley comprises a base having means for supporting said trolley for said horizontal reciprocating movement and a standard upstanding from said base, said carriage mounting means is fixed to said standard intermediate upper and lower portions thereof, and said door mounting means includes an upper mounting device for movably suspending said door from adjacent said upper portion of said standard and a pair of lower moutning devices movably connecting said door with said lower portion of said standard, said lower mounting devices being independently adjustable to produce vertical and horizontal tilting movements of said door relative to said trolley and said carriage mounting means.
Claim 7
Dependent Claim
57 words
A vessel according to claim 1, wherein said door mounting means is adjustable to produce vertical and horizontal tilting movements of said door relative to said trolley and said carriage mounting means to position said door sealing surface means for alignment with said shell sealing surface means when said door is moved into said closed position thereof.
