Abstract
Abstract An electrical power supply, particularly adapted for intermittent use, has an extremely long standby life. A series of squib actuated electrochemical batteries are controlled by a selective activation circuit, so that each reserve or secondary battery of the series is activated only after the preceding battery has substantially spent its useful life. The circuit responds to an increase in pressure within the battery encapsulation signaling the end of the battery''s useable lift, to substitute the next battery in the series, and to activated it by firing its squib.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
158 words
A power supply comprising: output terminals; a plurality of normally inactive batteries, said plurality of batteries each having an output voltage of zero when inactive and an output voltage greater than zero when active; means for activating a first one of said plurality of batteries; means responsive to internal battery pressure for sequentially activating said plurality of batteries, one at a time, after said first one has been activated when said internal battery pressure of said just previously activated battEry reaches an abnormal level; means for applying the output voltage of each of said plurality of batteries, including said first battery to said output terminals when said battery is activated; and means for removing the output voltage of each battery, except the last battery activated, when said internal battery pressure reaches said abnormal level, whereby said plurality of batteries are sequentially activated and the output voltage of each battery is sequentially applied and removed from said output terminals.
Claim 2
Dependent Claim
158 words
A power supply comprising: output terminals; a plurality of normally inactive batteries, said plurality of batteries each having an output voltage of zero when inactive and an output voltage greater than zero when active; means for activating a first one of said plurality of batteries; means responsive to internal battery pressure for sequentially activating said plurality of batteries, one at a time, after said first one has been activated when said internal battery pressure of said just previously activated battEry reaches an abnormal level; means for applying the output voltage of each of said plurality of batteries, including said first battery to said output terminals when said battery is activated; and means for removing the output voltage of each battery, except the last battery activated, when said internal battery pressure reaches said abnormal level, whereby said plurality of batteries are sequentially activated and the output voltage of each battery is sequentially applied and removed from said output terminals.
Claim 3
Dependent Claim
17 words
A power supply as defined in claim 1 wherein said plurality of batteries are dry charged batteries.
Claim 4
Dependent Claim
17 words
A power supply as defined in claim 1 wherein said plurality of batteries are reserve cell batteries.
Claim 5
Dependent Claim
99 words
A power supply as defined in claim 1 wherein said means for applying said output voltage of each battery to said output terminals when the battery is activated comprises a plurality of relays one less in number than the number of said plurality of batteries, said plurality of relays each having first and second normally closed contacts, each of said first contacts of said plurality of relays being coupled between said output terminals and a different one of said plurality of batteries except for the last battery activated, said last battery activated being directly connected to said output terminals.
Claim 6
Dependent Claim
83 words
A power supply as defined in claim 4 wherein said relays are each sequentially activated by a different battery of said plurality of batteries, except said first one, when the said battery associated with that relay is activated and means are provided to lock open said first and second contacts of each said relay when the relay is energized thereby permanently uncoupling the just previously activated battery from said output terminals when said internal battery pressure of that battery reaches said abnormal level.
Claim 7
Dependent Claim
26 words
A power supply as defined in claim 1 wherein said means for sequentially activating said plurality of batteries includes a piston arrangement associated with each battery.
Claim 8
Dependent Claim
135 words
A power supply as defined in claim 5 wherein a first and second plunger is provided with each of said batteries, said first plunger of each battery rising above the top of its associated battery when said internal battery pressure reaches said abnormal level; a movable mechanical linkage connecting said first plunger of each of said batteries to the said second plunger of the battery that is to be activated next after the battery with which the said first plunger is associated has been activated the movement of said first plunger to the top of its associated battery when its associated battery reaches said abnormal level of battery pressure being transmitted to its associated second plunger by said movable mechanical linkage in such a manner as to activate the battery associated with that second plunger.
Claim 9
Dependent Claim
17 words
A power supply as defined in claim 7 wherein said plurality of batteries are reserve cell batteries.
Claim 10
Dependent Claim
15 words
A power supply as defined in claim 7 wherein said batteries are dry charged batteries.
Claim 11
Dependent Claim
43 words
A power supply as defined in claim 6 wherein each one of said plurality of batteries except for the first one activated includes an explosive squib utilized to activate its associated battery, said first battery activated having a mechanical plunger for activation thereof.
Claim 12
Dependent Claim
86 words
A power supply as defined in claim 10 wherein said squibs are each provided with two electrical terminals for activation from the power available from the previously activated battery, said terminals of each squib being coupled to a single different battery in such a manner that the battery associated with that squib is activated from the power available from the battery to which said squib terminals are coupled when the battery pressure of said battery to which said squib terminals are coupled reaches said abnormal level.
Claim 13
Dependent Claim
101 words
A power supply as defined in claim 11 wherein separate switch means are utilized to couple said squibs to said single different battery, said switch means being connected between the first of said two squib terminals and one of the battery output terminals in such a manner that said first squib terminal of each squib is coupled to an output terminal of one battery different than the battery associated with said squib, the second terminal of said two terminals of each squib being connected directly to the other battery output terminal of the battery to which said first terminal is coupled.
Claim 14
Dependent Claim
42 words
A power supply as defined in claim 12 wherein each of said switches is so positioned that it is closed by said piston associated with the battery with which that switch is associated when the said battery pressure reaches an abnormal level.
