Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A positioning system for a built-up multiple unit structure comprising a plurality of spaced, rodlike jigs carried by a support surface in upstanding fashion and adapted to support the built-up structure at spaced positions, means associated with each jig for selectively adjusting the height thereof with respect to said support surface, central drive means for selectively actuating the adjusting means of each jig, central control means for feeding control signals to the driving means, and information storage means carrying predetermined positional format information for all of said jigs, and means associated with said central control means for deriving control signals from said information storage means.
Claim 2
Dependent Claim
105 words
A positioning system for a built-up multiple unit structure comprising a plurality of spaced, rodlike jigs carried by a support surface in upstanding fashion and adapted to support the built-up structure at spaced positions, means associated with each jig for selectively adjusting the height thereof with respect to said support surface, central drive means for selectively actuating the adjusting means of each jig, central control means for feeding control signals to the driving means, and information storage means carrying predetermined positional format information for all of said jigs, and means associated with said central control means for deriving control signals from said information storage means.
Claim 3
Dependent Claim
27 words
The system as claimed in claim 1 wherein said information storage means comprises a perforated tape carrying perforations indicative of the desired height of said individual jigs.
Claim 4
Dependent Claim
32 words
The system as claimed in claim 1 wherein said adjusting means comprises a pressurized fluid operated motor and said drive means comprises valve means for directing pressurized liquid to-and-from said fluid motor.
Claim 5
Dependent Claim
55 words
The positioning system as claimed in claim 1 wherein said support surface comprises a table mounted for pivoting about an axis at right angles to the axis of the individual rodlike jigs, and the system further includes motor means for pivoting said turn table about said axis and means for controlling said table drive motor.
Claim 6
Dependent Claim
31 words
The system as claimed in claim 2 wherein said control means comprises, a tape reading device, a decoder, a resistor, an output circuit, a digital-analogue converter circuit and an amplifying circuit.
