Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 191 words
In connector apparatus capable of making underwater fluid pressure connection with underwater equipment, the combination comprising a. upwardly opening receptacle means to be carried by the underwater equipment, said means having opposed interior faces which are substantially flat and which taper downwardly, there being ducting in the receptacle means and terminating at at least one of said faces, b. and a wedge shaped member displaced downwardly to seat in the receptacle means, said member having exterior faces which are substantially flat and which taper downwardly, there being ducting in said member and terminating at at least one of said exterior faces for communication with the ducting in the receptacle means in response to said seating, c. said receptacle means comprising first and second vertically interfitting receptacles, the first receptacle generally horizontally straddling the second receptacle and ducting extending in each of the receptacles and opening at generally horizontally spaced interior faces of the receptacles, and d. means supporting the second receptacle for yieldable downward deflection relative to the first receptacle so that the wedge shaped member seats downwardly initially against second receptacle interior faces and then against first receptacle interior faces.
Claim 2
Dependent Claim 191 words
In connector apparatus capable of making underwater fluid pressure connection with underwater equipment, the combination comprising a. upwardly opening receptacle means to be carried by the underwater equipment, said means having opposed interior faces which are substantially flat and which taper downwardly, there being ducting in the receptacle means and terminating at at least one of said faces, b. and a wedge shaped member displaced downwardly to seat in the receptacle means, said member having exterior faces which are substantially flat and which taper downwardly, there being ducting in said member and terminating at at least one of said exterior faces for communication with the ducting in the receptacle means in response to said seating, c. said receptacle means comprising first and second vertically interfitting receptacles, the first receptacle generally horizontally straddling the second receptacle and ducting extending in each of the receptacles and opening at generally horizontally spaced interior faces of the receptacles, and d. means supporting the second receptacle for yieldable downward deflection relative to the first receptacle so that the wedge shaped member seats downwardly initially against second receptacle interior faces and then against first receptacle interior faces.
Claim 3
Dependent Claim 40 words
The combinatiOn of claim 1 wherein said ducting comprises multiple ducts in the wedge shaped member and multiple ducts in the receptacle means, the duct openings in said faces of the wedge shaped member and receptacle means being in registration.
Claim 4
Dependent Claim 26 words
The combination of claim 2 including means locking said wedge shaped member to said receptacle means so that said exterior and interior faces are in interengagement.
Claim 5
Dependent Claim 46 words
The combination of claim 3 wherein said locking means includes bolt mechanism and an actuator therefor associated with the wedge shaped member, and keeper mechanism on one of the receptacles to receive the bolt mechanism in response to displacement of the bolt mechanism by the actuator.
Claim 6
Dependent Claim 32 words
The combination of claim 1 including a frame supporting the wedge shaped member, and multiple valves on the frame and having fluid pressure communication with the ducting in the wedge shaped member.
Claim 7
Dependent Claim 16 words
The combination of claim 1 including said equipment supporting said receptacle means at an underwater location.
Claim 8
Dependent Claim 16 words
The combination of claim 6 wherein said equipment comprises a stack of underwater well head equipment.
Claim 9
Dependent Claim 32 words
The combination of claim 7 including vertically movable structure supporting said member to depend therefrom, and valves on said structure in flow controlling communication with the ducts in the wedge shaped member.
Claim 10
Dependent Claim 18 words
The combination of claim 1 including support structure attached to each receptacle to accommodate relative vertical movement thereof.
Claim 11
Dependent Claim 31 words
The combination of claim 1 including said equipment having a first section supporting the first receptacle and a second section supporting the second receptacle, said second section being relatively vertically movable.
Claim 12
Dependent Claim 28 words
The combination of claim 10 wherein said equipment comprises a stack of underwater well head equipment, and means to elevate the first section relative to the second section.
Claim 13
Dependent Claim 16 words
