Abstract
Abstract Techniques are disclosed for supplying positive and negative voltages to electrical components in a system where power demand from the components needing voltage of one polarity is different from the power demand from components needing voltage of the other polarity. At least two batteries of substantially the same capacity are connected in series and used to supply the positive and negative voltages to the system components. In order to permit the batteries to be recharged simultaneously in series without damage to them the interconnection between the batteries and the loads are alternately reversed so that the batteries will discharge at substantially the same rate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A circuit for supplying positive and negative voltages to electrical components in a system where power demand from the components needing voltage of one polarity is different than the power demand from components needing voltage of the other polarity, said circuit comprising: at least two batteries of substantially the same capacity connected in series; a first load having at least one component therein needing a positive supply voltage with a given power demand; a second load having at least one component therein needing a negative supply voltage with a different power demand; and switching means interconnected between the batteries and the loads for alternately switching connection of the batteries to the loads to discharge the batteries at substantially the same rate whereby said batteries may be conveniently recharged simultaneously in series from a common recharging circuit.
Claim 2
Dependent Claim
136 words
A circuit for supplying positive and negative voltages to electrical components in a system where power demand from the components needing voltage of one polarity is different than the power demand from components needing voltage of the other polarity, said circuit comprising: at least two batteries of substantially the same capacity connected in series; a first load having at least one component therein needing a positive supply voltage with a given power demand; a second load having at least one component therein needing a negative supply voltage with a different power demand; and switching means interconnected between the batteries and the loads for alternately switching connection of the batteries to the loads to discharge the batteries at substantially the same rate whereby said batteries may be conveniently recharged simultaneously in series from a common recharging circuit.
Claim 3
Dependent Claim
20 words
The circuit of claim 1 wherein said switching means comprises a relay which is switched as a function of time.
Claim 4
Dependent Claim
198 words
An electrical system comprising: a first load having at least one electrical component therein needing a positive supply voltage with a given power demand; a second load having at least one electrical component therein needing a negative supply voltage with a different power demand; an A/C power source; a rechargeable battery supply having at least two batteries of substantially the same capacity connected together in series; a battery charging circuit connected in parallel across said series connected batteries and being powered from said A/C power source; and switching means interconnected between the batteries and the loads for periodically switching the connection therebetween, operative in a first position to connect one battery across said first load and the other battery across said second load, and being further operative in a second position to reverse the connection such that said one battery is connected across said second load and said other battery is connected across said first load whereby said batteries are discharged at substantially the same rate when said loads are powered by said batteries and wherein said batteries are automatically recharged in series from said battery charging circuit when the loads are powered by said A/C power source.
Claim 5
Dependent Claim
198 words
An electrical system comprising: a first load having at least one electrical component therein needing a positive supply voltage with a given power demand; a second load having at least one electrical component therein needing a negative supply voltage with a different power demand; an A/C power source; a rechargeable battery supply having at least two batteries of substantially the same capacity connected together in series; a battery charging circuit connected in parallel across said series connected batteries and being powered from said A/C power source; and switching means interconnected between the batteries and the loads for periodically switching the connection therebetween, operative in a first position to connect one battery across said first load and the other battery across said second load, and being further operative in a second position to reverse the connection such that said one battery is connected across said second load and said other battery is connected across said first load whereby said batteries are discharged at substantially the same rate when said loads are powered by said batteries and wherein said batteries are automatically recharged in series from said battery charging circuit when the loads are powered by said A/C power source.
Claim 6
Dependent Claim
20 words
The system of claim 3 wherein said switching means comprises a relay which is switched as a function of time.
