Abstract
Abstract A hanger system particularly for cyclone collectors in a fluidized particle process vessel, such as a fluid catalytic cracker regenerator vessel, wherein a vertical supporting member is pinned at one end to a cyclone wall lug and at the other through a slot in a vessel depending lug so that thermal and mechanical stresses within the overall assembly are compensated for by sliding movement of the pin in the slot, which movement is controlled by a stabilizing linkage member attached to the pin at one end and pivotably attached at the other end to the vessel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
212 words
A hanger system for mounting an internal vessel in a depending position to a bulkhead wall of an external vessel comprising: a. a first lug fixedly connected to a wall of the internal vessel, means forming an aperture in said first lug; b. a second lug fixedly connected to and depending from a wall of the external vessel, means forming a longitudinal extending slot in said second lug; c. a support member pinned through the aperture in said first lug and vertically extending to said second lug to support said internal vessel; d. pin means within said slot connecting said support member to said second lug, said slot having horizontal and vertical components of direction permitting sliding movement of said support member with respect to the second lug; e. an elongated stabilizing linkage member extending generally parallel to the direction of said slot, said linkage member having means forming an aperture adjacent each end thereof, said pin means extending through the aperture at one end of said linkage member permitting movement of said pin means within the slot; and f. means including a second pin means for pinnedly connecting the end of said linkage member opposite the slot to a portion of said external vessel wall spaced from said second lug location.

A hanger system for mounting an internal vessel in a depending position to a bulkhead wall of an external vessel comprising: a. a first lug fixedly connected to a wall of the internal vessel, means forming an aperture in said first lug; b. a second lug fixedly connected to and depending from a wall of the external vessel, means forming a longitudinal extending slot in said second lug; c. a support member pinned through the aperture in said first lug and vertically extending to said second lug to support said internal vessel; d. pin means within said slot connecting said support member to said second lug, said slot having horizontal and vertical components of direction permitting sliding movement of said support member with respect to the second lug; e. an elongated stabilizing linkage member extending generally parallel to the direction of said slot, said linkage member having means forming an aperture adjacent each end thereof, said pin means extending through the aperture at one end of said linkage member permitting movement of said pin means within the slot; and f. means including a second pin means for pinnedly connecting the end of said linkage member opposite the slot to a portion of said external vessel wall spaced from said second lug location.
Claim 3
Dependent Claim
26 words
The invention set forth in claim 1 in which said pin means includes opposed flatten portions in sliding engagement with longitudinal edge portions of said slot.
Claim 4
Dependent Claim
47 words
The invention set forth in claim 1 in which said support member and said linkage member each comprise a pair of metal straps, each strap of a pair being parallel to the other of that pair and situate on opposite sides of said first and second lugs.
Claim 5
Dependent Claim
38 words
The invention as set forth in claim 1 in which said support member and said linkage member each comprise rod elements having clevises at each end for attachment to said first and second lugs and said external vessel.
Claim 6
Dependent Claim
32 words
The invention as set forth in claim 1 in which said internal vessel is a cyclone collector and said first lug upstands from a top substantially horizontal surface of said cyclone collector.
Claim 7
Dependent Claim
37 words
The invention as set forth in claim 1 further including a third lug member depending from said external vessel wall to which the linkage member is connected at its end opposite the slot in said second lug.
