Abstract
Abstract A sealed tube system solidly-filled with liquid. One end of the system is elastically deformable by pressure, which deformation is transmitted by the liquid to the other end, which elastically deforms likewise. A thimble and socket connection provides for disconnecting and reconnecting the two ends of the system. The connection is such that if it is used to disconnect and reconnect the ends, then, after reconnection, a given deformation of the one end will cause the same deformation of the other end as it did before disconnection.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
In a volumetric measuring system having a sealed envelope solidly-filled with substantially incompressible liquid, wherein said envelope includes a sensing portion responsive to a condition for causing the internal pressure of said liquid to correspond to said condition, wherein said envelope includes a signal portion responsive to said internal pressure for producing a signal corresponding to said internal pressure, and wherein said envelope includes a capillary portion for transmitting internal pressure changes between said sensing and signal portions; the improvement wherein said capillary portion has a thimble and a socket each forming a part of said capillary portion, and said socket and said thimble being forcibly interengaged for urging said Thimble and socket into contact with each with such force as to strain the material thereof continuously throughout a given area of mutual contact, said thimble and socket each having a capillary passage having openings within said area and registering with one another for defining the thimble and socket parts of said capillary portion.
Claim 2
Dependent Claim
164 words
In a volumetric measuring system having a sealed envelope solidly-filled with substantially incompressible liquid, wherein said envelope includes a sensing portion responsive to a condition for causing the internal pressure of said liquid to correspond to said condition, wherein said envelope includes a signal portion responsive to said internal pressure for producing a signal corresponding to said internal pressure, and wherein said envelope includes a capillary portion for transmitting internal pressure changes between said sensing and signal portions; the improvement wherein said capillary portion has a thimble and a socket each forming a part of said capillary portion, and said socket and said thimble being forcibly interengaged for urging said Thimble and socket into contact with each with such force as to strain the material thereof continuously throughout a given area of mutual contact, said thimble and socket each having a capillary passage having openings within said area and registering with one another for defining the thimble and socket parts of said capillary portion.
Claim 3
Dependent Claim
18 words
The invention of claim 1, wherein means including a rigid member forcibly interengages said thimble and said socket.
Claim 4
Dependent Claim
10 words
The invention of claim 1, wherein said liquid is mercury.
Claim 5
Dependent Claim
10 words
The invention of claim 1, wherein said liquid is silicone.
Claim 6
Dependent Claim
47 words
The invention of claim 1, wherein said socket and said thimble have, respectively, a concave surface and a convex surface including the said given area of mutual contact, said concave surface having a lesser slope generally than said convex surface at said given area of mutual contact.
Claim 7
Dependent Claim
56 words
The invention of claim 5, wherein said convex and concave surfaces are cones, and the cone apex of the convex surface is truncated at said given area to provide a peripheral portion of said convex surface biting into the adjacent portion of said concave surface, due to the force of interengagement of said thimble and socket.
Claim 8
Dependent Claim
164 words
A volumetric measuring system consisting essentially of an envelope solidly-filled with substantially incompressible liquid, said envelope having, as part thereof, a thimble and socket, said thimble having a convex surface and a first bore, said socket having a concave surface corresponding to said convex surface and a second bore, each said bore having an opening through the corresponding surface and being surrounded thereby; said thimble and socket mating with one another with the said bore openings registering with each other, and with the circumadjacent portions of said surfaces contacting each other; and there being clamping means forcibly holding said thimble and socket in mutual contact at said portions; said concave surface having a lesser slope generally than said convex surface so that the extent of contact of said circumadjacent portions is proportional to the force with which said clamping means holds said thimble and socket together, and said force being sufficient to strain the material of said thimble and socket at said circumadjacent portions.
Claim 9
Dependent Claim
164 words
A volumetric measuring system consisting essentially of an envelope solidly-filled with substantially incompressible liquid, said envelope having, as part thereof, a thimble and socket, said thimble having a convex surface and a first bore, said socket having a concave surface corresponding to said convex surface and a second bore, each said bore having an opening through the corresponding surface and being surrounded thereby; said thimble and socket mating with one another with the said bore openings registering with each other, and with the circumadjacent portions of said surfaces contacting each other; and there being clamping means forcibly holding said thimble and socket in mutual contact at said portions; said concave surface having a lesser slope generally than said convex surface so that the extent of contact of said circumadjacent portions is proportional to the force with which said clamping means holds said thimble and socket together, and said force being sufficient to strain the material of said thimble and socket at said circumadjacent portions.
Claim 10
Dependent Claim
49 words
The volumetric measuring system of claim 7, wherein said concave and convex surfaces are cones, and the cone apex of the convex surface is truncated to provide a peripheral portion of said convex surface biting into the adjacent surface portion of said concave surface, due to the said force.
Claim 11
Dependent Claim
12 words
The volumetric measuring system of claim 7, wherein said liquid is mercury.
Claim 12
Dependent Claim
12 words
The volumetric measuring system of claim 7, wherein said liquid is silicone.
