Abstract
Abstract Device for generating electric pulses on superconductor loops particularly for instrumentation to determine the position and change of position of aircraft and spacecraft. An adapter preferably of Type I superconductor is installed in a superconductor loop, preferably of Type II superconductor, the ends of the adapter having insulating layers and carrying signal input layers and carrying signal input layers on one side thereof and current collecting layers on the other side thereof. A signal transmitter controls both the signal input layers and the current collecting layers and an auxiliary coil is provided for producing normal conductivity within an intermediate range.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
157 words
A device for moving bodies for navigation purposes, particularly in aircraft and spacecraft, to determine the change in orientation thereof, comprising: electrical pulse generator means for generating pulses; superconductor means connected in electrical circuit with said electrical pulse generator means for generating pulsed magnetic fields in response to said pulses; superconductor loop means having opposite end segments; adapter means connected in electrical circuit with said superconductor loop means and magnetically coupled to said superconductor means so as to receive the pulsed magnetic fields and for transmitting current pulses in response thereto to said opposite end segments of said superconductor loop means to effect a propagation of a current signal in opposite directions along said superconductor loop means; and signal collecting means for detecting said propagated signals after said signals have passed through said superconductor loop means and provide signal means for measurement, via the Sagnac effect, to determine the shift or phase shift of said propagated signals.
Claim 2
Independent Claim
157 words
A device for moving bodies for navigation purposes, particularly in aircraft and spacecraft, to determine the change in orientation thereof, comprising: electrical pulse generator means for generating pulses; superconductor means connected in electrical circuit with said electrical pulse generator means for generating pulsed magnetic fields in response to said pulses; superconductor loop means having opposite end segments; adapter means connected in electrical circuit with said superconductor loop means and magnetically coupled to said superconductor means so as to receive the pulsed magnetic fields and for transmitting current pulses in response thereto to said opposite end segments of said superconductor loop means to effect a propagation of a current signal in opposite directions along said superconductor loop means; and signal collecting means for detecting said propagated signals after said signals have passed through said superconductor loop means and provide signal means for measurement, via the Sagnac effect, to determine the shift or phase shift of said propagated signals.
Claim 3
Dependent Claim
37 words
A device according to claim 1, wherein said adapter means includes first insulative means between said superconductor means and said superconductor loop means and second insulative means between said superconductor loop means and said signal collecting means.
Claim 4
Dependent Claim
47 words
A device according to claIm 1, including interference preventing means responsive to said electrical pulse generator means for preventing an interference of said propagated signals during the interval of time that said adapter means is effecting an application of said current signal to said superconductor loop means.
Claim 5
Dependent Claim
31 words
A device according to claim 3, wherein the interference preventing means comprises a coil connected in magnetic association with said adaptor means between said opposite end segments of said superconductor loop.
Claim 6
Dependent Claim
48 words
A device according to claim 1, wherein said adapter means includes lead or tin layers vapor deposited on quartz; and wherein said opposite end segments of said superconductor loop means are vapor deposited on said lead or tin layers and said layers are insulated from said superconductor means.
