Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
211 words
A mounting and shock absorber assembly for borehole telemetry apparatus, including: first bumper means; second bumper means following said first bumper means; a plurality of mounting rings following said second bumper means; said first and second bumper means and said plurality of mounting rings being in a sequential axial array along the axis of a device to be mounted; each of said bumper means having an outer ring, an inwardly projecting annular rib, annular elastomeric bumper elements adhered to each side of said rib, a pair of inner rings and an outwardly extending annular rib from each of said inner rings in opposed relationship to said elastomeric bumper elements; each of said mounting rings having an outer ring, an inner ring, and elastomeric material extending between and being adhered to said rings; the outer rings of said bumper means and the outer rings of said mounting rings being connected to an outer support sleeve, and the inner rings of said bumper means and the inner rings of said mounting rings being connected to structure to be mounted for suspension and shock absorption; means defining a flow path for fluid through said assembly; and means for locking said assembly against rotation of said structure to be mounted relative to said support sleeve.
Claim 2
Dependent Claim
211 words
A mounting and shock absorber assembly for borehole telemetry apparatus, including: first bumper means; second bumper means following said first bumper means; a plurality of mounting rings following said second bumper means; said first and second bumper means and said plurality of mounting rings being in a sequential axial array along the axis of a device to be mounted; each of said bumper means having an outer ring, an inwardly projecting annular rib, annular elastomeric bumper elements adhered to each side of said rib, a pair of inner rings and an outwardly extending annular rib from each of said inner rings in opposed relationship to said elastomeric bumper elements; each of said mounting rings having an outer ring, an inner ring, and elastomeric material extending between and being adhered to said rings; the outer rings of said bumper means and the outer rings of said mounting rings being connected to an outer support sleeve, and the inner rings of said bumper means and the inner rings of said mounting rings being connected to structure to be mounted for suspension and shock absorption; means defining a flow path for fluid through said assembly; and means for locking said assembly against rotation of said structure to be mounted relative to said support sleeve.
