Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A waste disintegrator to be inserted into the flow of a fluid containing solid particles for comminuting the solid particles in fluid as it is passing therethrough comprising: a housing having a transverse wall that blocks the flow of fluid through the disintegrator, said transverse wall having its central area cut away to form a first opening through which the fluid is channeled, comminuting means mounted in said opening to substantially close said opening, a second opening in said wall to pass the fluid in a path through said waste disintegrator that bypasses said comminuting means, a normally closed fluid bypass valve means positioned along said path, means maintaining said valve normally closed but responsive to pressure differential across said wall to allow said valve to open.
Claim 2
Dependent Claim
127 words
A waste disintegrator to be inserted into the flow of a fluid containing solid particles for comminuting the solid particles in fluid as it is passing therethrough comprising: a housing having a transverse wall that blocks the flow of fluid through the disintegrator, said transverse wall having its central area cut away to form a first opening through which the fluid is channeled, comminuting means mounted in said opening to substantially close said opening, a second opening in said wall to pass the fluid in a path through said waste disintegrator that bypasses said comminuting means, a normally closed fluid bypass valve means positioned along said path, means maintaining said valve normally closed but responsive to pressure differential across said wall to allow said valve to open.
Claim 3
Dependent Claim
55 words
A waste disintegrator as recited in claim 1 wherein said fluid bypass valve means comprises flapper door means pivotally mounted in the said path, spring means having its opposite ends attached to said housing and said flapper door means, respectively, to keep said flapper door closed when the pressure differential is below a predetermined level.
Claim 4
Dependent Claim
54 words
A waste disintegrator as recited in claim 2 further comprising a switch in a warning signal circuit, said switch being open when said flapper door is closed and the switch being closed when said flapper door is open, said flapper door means having structure that contacts said switch to open and close said switch.
Claim 5
Dependent Claim
55 words
A waste disintegrator as recited in claim 1 wherein a predetermined portion of the transverse wall has a shroud extending from its downstream face, said shroud being located about at least a portion of said first opening, thereby helping to maintain a laminar flow of the fluid after it has passed through said first opening.
Claim 6
Dependent Claim
89 words
A waste disintegrator as recited in claim 2 wherein said flapper door means further comprises a shaft passing through a wall of said housing with a portion of its length both above and below said wall of the housing, said shaft having its lower end journalled in a bearing block, the flapper door being fixedly secured to said shaft in the area above said bearing block and below the wall of the housing so that as the flapper door opens and closes, the flapper shaft rotates back and forth.
Claim 7
Dependent Claim
52 words
A waste disintegrator as recited in claim 5 wherein said flapper door means further comprises an arm fixedly secured to the portion of the flapper shaft extending above the wall of the housing whereby as the flapper door opens and closes, the arm rotates in and out of contact with the switch.
Claim 8
Dependent Claim
94 words
A waste disintegrator as recited in claim 6 wherein said spring means comprises a coil spring whose one end is secured to portion on the arm and whose other end is secured to a portion of the housing at a point adjacent to the axis of the flapper shaft axis whereby when the flapper door is forced open to its maximum open position, the amount of elongation of said spring is insignificant and the angle of pull diminishes to thus maintain a relatively constant spring tension that continues to urge the flapper door closed.
