Interconnecting circuit for connecting one d.c. voltage source to another
First Claim
1. An interconnecting circuit for connecting a first d.c. source to a second d.c. source, the circuit comprising first means responsive to connection polarity of the one voltage source for developing a ONE signal whenever a given connection polarity of the first source is present and a ZERO signal whenever a connection polarity opposite to the given connection polarity of the first source is present;
- second means responsive to connection polarity of the second d.c. source for developing a ONE signal whenever a given connection polarity of the second source is present and a ZERO signal whenever a connection polarity opposite to the given connection polarity of the second source is present;
exclusive OR gate circuit means responsive to the outputs from said first means and said second means for developing a control signal; and
relay means having first and second conditions, said relay means being responsive to the control signal, wherein said relay means includes two normally open pairs of contacts for connecting a first terminal of the first source to a first terminal of the second source and a second terminal of the first source to a second terminal of the second whenever the relay means is in its first condition and wherein said relay means further includes two normally closed pairs of contacts for connecting the first terminal of the first source to the second terminal of the second source and the second terminal of the first source to the first terminal of the second source whenever said relay means is in its second condition.

Abstract
An interconnecting circuit for connecting a first d.c. source to a second d.c. source. The circuit includes a first conductive connection extending between one terminal of the first source and one terminal of the second source, the first conductive connection including a first pair of relay contacts and a second pair of relay contacts. A second conductive connection extends between a second terminal of the first source and a second terminal of the second source, the second conductive connection being free of relay contacts. A first polarity responsive circuit includes a first relay winding coupled across the first d.c. source for energizing the first relay winding whenever the first d.c. source is connected in a given polarity, the first pair of contacts being closed whenever the first relay winding is energized. A second polarity responsive circuit includes a second relay winding coupled across the second d.c. source for energizing the second relay winding whenever the second d.c. source is connected in the given polarity. The second pair of contacts are closed whenever said second relay winding is energized.
