Abstract
Abstract In an antisubmarine warfare training device a speed and bearing integrator is provided to control the simulation of a submarine ''''signature.'''' Differentially interconnected speed and bearing setting means are used to selectively position two readout heads on a rotating disk having two sets of information recorded thereon. Speed and bearing controls can be adjusted independently without affecting each other.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
283 words
In a sonar training device having means for indicating speed and bearing of a simulated submarine target, the improvement comprising: bearing control means for controlling the bearing indication of a simulated submarine target, speed control means for controlling the speed indication of a simulated submarine target, differential means connecting said control means whereby either of said bearing control means or said speed control means may be adjusted without affecting the indication of the other, bearing indication signal generating means, speed indication signal generating means, said differential means including means for adjusting said bearing indication signal generating means when said speed control means are adjusted, said bearing indication signal generating means and said speed indication signal generating means comprising a rotating disk having a plurality of submarine signature information bearing tracks recorded thereon, a first fixed readout head positioned to read out information from a first of said tracks, a first moveable readout head positioned to read out information from a second of said tracks, a second fixed readout head positioned to read out information from a third of said tracks, a second moveable readout head positioned to read out information from a fourth of said tracks, the information read out by said first readout heads being adapted to be combined into a first bearing indication, the information read out by said second readout heads being adapted to be combined into a second bearing indication, said bearing control means including means for adjusting said first bearing indication by moving said first moveable readout head with respect to said first fixed head, and means for adjusting said second bearing indication by moving said second moveable readout head with respect to said second fixed readout head.
Claim 2
Dependent Claim
283 words
In a sonar training device having means for indicating speed and bearing of a simulated submarine target, the improvement comprising: bearing control means for controlling the bearing indication of a simulated submarine target, speed control means for controlling the speed indication of a simulated submarine target, differential means connecting said control means whereby either of said bearing control means or said speed control means may be adjusted without affecting the indication of the other, bearing indication signal generating means, speed indication signal generating means, said differential means including means for adjusting said bearing indication signal generating means when said speed control means are adjusted, said bearing indication signal generating means and said speed indication signal generating means comprising a rotating disk having a plurality of submarine signature information bearing tracks recorded thereon, a first fixed readout head positioned to read out information from a first of said tracks, a first moveable readout head positioned to read out information from a second of said tracks, a second fixed readout head positioned to read out information from a third of said tracks, a second moveable readout head positioned to read out information from a fourth of said tracks, the information read out by said first readout heads being adapted to be combined into a first bearing indication, the information read out by said second readout heads being adapted to be combined into a second bearing indication, said bearing control means including means for adjusting said first bearing indication by moving said first moveable readout head with respect to said first fixed head, and means for adjusting said second bearing indication by moving said second moveable readout head with respect to said second fixed readout head.
Claim 3
Dependent Claim
70 words
The apparatus of claim 1, said bearing control means comprising a rotatable bearing control wheel having an integral indicating dial rotatable therewith, variable speed driving means for rotating said rotating disk, said speed control means comprising a rotatable speed control wheel having an integral indicating dial rotatable therewith, and connecting means connecting said speed control means to said variable speed drive means to vary the speed of said rotating disk.
