Abstract
Abstract A static press of relatively simple construction is provided having first and second spaced apart stationary plates, a movable third plate intermediate said first and second plates and a flexible conduit in the form of an annulus separating the first and third plates. The conduit defines a chamber which is enclosed by the first and third plates. An object is introduced between the second and third plates with a small amount of headroom, so that upon pressurizing the conduit the object is pressed between the plates and the chamber hermetically sealed. The chamber is then pressurized to provide a uniform work force against the object. When the object is to be released, the pressure in the chamber and conduit is released, lowering the object out of engagement with the second plate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
88 words
A pressure actuated static press for holding a member under compression comprising: first and second plates in spaced apart relationship on opposite sides of said member; a platen intermediate said first plate and said member; an inflatable ring separating said first plate and platen and defining a chamber interiorly of said ring, and means for pressurizing said ring and said chamber to inflate said ring and urge said member into compressive engagement with said second plate, hermetically sealing said chamber and holding said member under relatively uniform compression.
Claim 2
Dependent Claim
88 words
A pressure actuated static press for holding a member under compression comprising: first and second plates in spaced apart relationship on opposite sides of said member; a platen intermediate said first plate and said member; an inflatable ring separating said first plate and platen and defining a chamber interiorly of said ring, and means for pressurizing said ring and said chamber to inflate said ring and urge said member into compressive engagement with said second plate, hermetically sealing said chamber and holding said member under relatively uniform compression.
Claim 3
Dependent Claim
35 words
A static press according to claim 1, wherein said ring has opposed ridges on the outer surface of said ring, and said first plate and said platen have grooves in cooperative engagement with said ridges.
Claim 4
Dependent Claim
19 words
A press according to claim 1, wherein said pressurizing means has valve and gauge means for controlling the pressure.
Claim 5
Dependent Claim
31 words
A press according to claim 1 having in combination, adjustment means operably connected to one of said first and second plates for adjusting the spacing between said first and second plates.
Claim 6
Dependent Claim
14 words
A press according to claim 1, wherein said ring has a substantially rectangular configuration.
Claim 7
Dependent Claim
14 words
A press according to claim 1, wherein said ring has an oblate cross section.
Claim 8
Dependent Claim
102 words
A pressure actuated static press for holding a member in compression comprising: a housing having spaced apart horizontal lower and upper plates, means for adjusting the spacing between said upper and lower plates operably connected to said upper plate; a flexible inflatable annular conduit positioned on said lower plate; a platen freely riding on said flexible conduit, said lower plate, platen and conduit defining a chamber; and means for pressurizing said conduit and said chamber to inflate said conduit and urge said member in compressive engagement with said upper plate hermetically sealing said chamber and holding said member under relatively uniform compression.
Claim 9
Dependent Claim
102 words
A pressure actuated static press for holding a member in compression comprising: a housing having spaced apart horizontal lower and upper plates, means for adjusting the spacing between said upper and lower plates operably connected to said upper plate; a flexible inflatable annular conduit positioned on said lower plate; a platen freely riding on said flexible conduit, said lower plate, platen and conduit defining a chamber; and means for pressurizing said conduit and said chamber to inflate said conduit and urge said member in compressive engagement with said upper plate hermetically sealing said chamber and holding said member under relatively uniform compression.
Claim 10
Dependent Claim
32 words
A static press according to claim 7, wherein said conduit has upper and lower ridges and said lower plate and platen have grooves for cooperative engagement with said upper and lower ridges.
Claim 11
Independent Claim
113 words
A method for maintaining a member under compression which comprises: introducing said member between a movable plate and a fixed plate, wherein said movable plate rests upon an inflatable ring having inflating means, said ring being situated on an immobile surface and wherein said ring, said movable plate and said immobile surface define a chamber, inflating said ring so as to move said member against said fixed plate and compressing said member and said ring, forming an hermetic seal between said ring, said movable plate and said immobile surface, and, pressurizing said chamber to a pressure below the pressure in said ring, so as to provide a substantially uniform pressure against said member.
Claim 12
Independent Claim
113 words
