Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
193 words
Delivery system for loading and unloading of tankers using a crane tower and a boom supported in cantilever configuration by the tower for pivoting on the top of the tower, the cantilever having weight balancing extension; the improvement comprising: a support arm pivotally suspended from the end of the boom arm and having girders carried by the boom arm; first pipe means suspended from the top of the tower and disposed for running up in the tower; second pipe means suspended from the girders of the boom arm and supported by the boom arm in multiple spaced-apart points along the extension of the arm including support points displaced from either end of the second pipe means; and third pipe means supported in multiple, spaced-apart points in the suspended arm; the first, second and third pipe means fluid conductively interconnected to obtain continuous, closed conduit means for fluid, there being a turning joint between first and second pipe means and a turning joint between the second and third joint means, only one thereof being secured to the boom arm for compensation of changes in length of the second pipe means due to temperature variations.

Claim 3
Dependent Claim
44 words
Delivery system as in claim 1, the tower provided for turning the boom on a vertical axis and for pivoting the boom on a horizontal axis, boom and tower disposed for the second pipe to turn and to pivot respectively on the same axes.
Claim 4
Dependent Claim
33 words
Delivery system as in claim 1, the first pipe means suspended from the top of the tower, and means on the first pipe means for compensation of length variations upon changes in temperature.
Claim 5
Dependent Claim
30 words
System as in claim 3, the first pipe means having first and second sections, there being a turning joint interconnecting the first and second sections underneath suspension from the tower.
Claim 6
Dependent Claim
110 words
System as in claim 1, the boom comprised of two parallely, disposed girders linked for parallel motion, there being an upper and a lower girder, the lower one of the two girders pivotally linked to the tower, the free ends of the two girders linked by a pendulum suspension for and rigidly extending from the suspended arm, the upper one of the two girders extended to the rear and carrying a balancing weight, the second pipe disposed in the lower girder, there being means providing pendulum suspension for the second pipe from the upper girder, acting on the pipe in between the respective joints to the first and third pipe.
Claim 7
Dependent Claim
49 words
System as in claim 1, the second pipe positioned in the boom for sliding motion due to temperature variations, the joint to the first pipe being stationary, the third pipe mounted to the suspended arm for motion relative to each other, there being pivot means provided for the mounting.
Claim 8
Dependent Claim
27 words
System as in claim 1, there being means for mounting the pipes respectively to tower, boom and arm, the means, at least partially, having low thermal conductivity.
Claim 9
Dependent Claim
16 words
System as in claim 7, the first, second and third pipe means clad in thermal insulation.
Claim 10
Dependent Claim
24 words
System as in claim 1, the pipe means each including at least two pipes running parallel to each other for establishing separate fluid paths.
Claim 11
Dependent Claim
115 words
System as in claim 9, the first, second and third pipe means, respectively, comprised of first, second and third pluralities of pipes, the pipes of the second plurality disposed in a plane, and respectively joined to the pipes of the third plurality disposed in a different plane, the pipes of the first plurality joined to the pipes of the second plurality permitting turning motion about the axis of the boom, the pipes of the first plurality being suspended from the tower, and conduit means at the lower ends of the pipes of the first plurality for compensating position changes upon turning of the pipes of the first plurality as a whole about a vertical axis.
Claim 12
Dependent Claim
13 words
System as in claim 9, the several pipes releasably disposed for individual removal.
Claim 13
Dependent Claim
17 words
System as in claim 9, the balancing weight and the effective length of the extension being adjustable.
