Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
A method for producing a spring manometer measuring system consisting of an indicator, a spring serving as a deviation detector and a tie rod connecting the indicator to the spring, a bearing defining an end point being produced on the spring for one end of said tie rod and a second bearing defining a pivot point for the other end of said tie rod being produced on the indicator and the tie rod articulating with both bearings, the spring being subjected to a specific reference pressure while the deflection of said spring is being measured, the deflection of the spring being measured before the bearings are produced for the tie rod and the geometric locations at which the bearing on the spring and the second bearing are produced being determined from the measured deflection on the basis of experimentally ascertained or calculated associations.
Claim 2
Independent Claim
143 words
A method for producing a spring manometer measuring system consisting of an indicator, a spring serving as a deviation detector and a tie rod connecting the indicator to the spring, a bearing defining an end point being produced on the spring for one end of said tie rod and a second bearing defining a pivot point for the other end of said tie rod being produced on the indicator and the tie rod articulating with both bearings, the spring being subjected to a specific reference pressure while the deflection of said spring is being measured, the deflection of the spring being measured before the bearings are produced for the tie rod and the geometric locations at which the bearing on the spring and the second bearing are produced being determined from the measured deflection on the basis of experimentally ascertained or calculated associations.
Claim 3
Dependent Claim
24 words
A method according to claim 1, wherein the deflection of the spring is measured under the reference pressure which is greater than nominal pressure.
Claim 4
Dependent Claim
28 words
A method according to claim 1, wherein the measurement is made after the spring manometer measuring system has been completely assembled with the exception of the tie rod.
Claim 5
Dependent Claim
12 words
A method according to claim 1, wherein both bearings are produced simultaneously.
Claim 6
Dependent Claim
42 words
A method according to claim 1, wherein an end piece is disposed on the spring and the indicator has a segment lever, and the bearings are drilled or punched in the end piece and the segment lever in the form of holes.
Claim 7
Dependent Claim
39 words
A method according to claim 1, wherein an end piece is disposed on the spring and the indicator has a segment lever, and pre-fabricated bearings are affixed and welded to the end piece and segment lever and secured thereto.
Claim 8
Dependent Claim
44 words
A method according to claim 4, wherein the indicator is maintained in a mechanically defined final position during the production of the bearings, while at the same time the spring is subjected to the pressure which is suppressed at point zero of the indicator.
Claim 9
Independent Claim
140 words
A method for producing a spring manometer measuring system consisting of an indicator, a spring serving as a deviation detector and a tie rod connecting the indicator to the spring, a bearing defining an end point being produced on the spring for one end of said tie rod and a second bearing defining a pivot point for the other end of said tie rod being produced on the indicator and the tie rod articulating with both bearings, the spring being subjected to a specific reference pressure while the deflection of said spring is being measured, the deflection of the spring being measured before one of the two bearings is produced for the tie rod and the geometrical location at which this one bearing is produced is determined from the measured deflection on the basis of experimentally ascertained or calculated associations.
Claim 10
Independent Claim
140 words
A method for producing a spring manometer measuring system consisting of an indicator, a spring serving as a deviation detector and a tie rod connecting the indicator to the spring, a bearing defining an end point being produced on the spring for one end of said tie rod and a second bearing defining a pivot point for the other end of said tie rod being produced on the indicator and the tie rod articulating with both bearings, the spring being subjected to a specific reference pressure while the deflection of said spring is being measured, the deflection of the spring being measured before one of the two bearings is produced for the tie rod and the geometrical location at which this one bearing is produced is determined from the measured deflection on the basis of experimentally ascertained or calculated associations.
Claim 11
Dependent Claim
24 words
A method according to claim 8, wherein the deflection of the spring is measured under the reference pressure which is greater than nominal pressure.
Claim 12
Dependent Claim
26 words
A method according to claim 8, wherein the measurement is made after the spring manometer measuring system has been completely assembled except for the tie rod.
Claim 13
Dependent Claim
19 words
A method according to claim 8, wherein the bearing which is produced after the measurement is the second bearing.
Claim 14
Dependent Claim
43 words
A method according to claim 8, wherein an end piece is disposed on the spring and the indicator has a segment lever, and the bearing is drilled or punched in the end piece or the segment lever in the form of a hole.
Claim 15
Dependent Claim
40 words
A method according to claim 8, wherein an end piece is disposed on the spring and the indicator has a segment lever, and a pre-fabricated bearing is affixed or welded to the end piece or segment lever and secured thereto.
