Abstract
Abstract This invention relates to a power supply for generating an electrical pulse. More particularly, the invention is a power supply for generating an electrical pulse including a housing, at least one coil of wire supported by the housing, a magnetic rotor supported by the housing and rotatable relative to the coil, and spring means interconnected to the magnetic rotor and adapted upon unwinding of the spring means to rotate the magnetic rotor relative to the coil to induce a voltage pulse in the coil.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A power supply for generating an electrical pulse comprising: a housing; a coil supported by said housing; a rotatably supported rotor shaft having a slotted end; a magnetic member supported by said shaft; a spring assembly interconnected to said shaft and adapted to store energy when in a wound state; a release pawl pivotally secured to said housing and engageable with said shaft slotted end to retain said shaft in a wound state; and means carried by said housing to pivot said release pawl from engagement with said shaft slotted end whereby said spring unwinds, causing rotation of said shaft and said magnetic member relative to said coil to induce voltage in said coil.
Claim 2
Dependent Claim
114 words
A power supply for generating an electrical pulse comprising: a housing; a coil supported by said housing; a rotatably supported rotor shaft having a slotted end; a magnetic member supported by said shaft; a spring assembly interconnected to said shaft and adapted to store energy when in a wound state; a release pawl pivotally secured to said housing and engageable with said shaft slotted end to retain said shaft in a wound state; and means carried by said housing to pivot said release pawl from engagement with said shaft slotted end whereby said spring unwinds, causing rotation of said shaft and said magnetic member relative to said coil to induce voltage in said coil.
Claim 3
Dependent Claim
26 words
A power supply for generating an electrical pulse as in claim 1 including a plurality of coils supported by said housing and encompassing said magnetic member.
Claim 4
Dependent Claim
49 words
A power supply for generating an electrical pulse as in claim 1 including electrical means adopted to pivotally disengage said pawl from said slotted end of said extension arbor whereby said spring unwinds causing rotation of said magnetic member relative to said coil to induce voltage in said coil.
Claim 5
Dependent Claim
37 words
A power supply for generating an electrical pulse as in claim 1 including a leaf spring for prohibiting reengagement of said pawl into said slotted end of said extension arbor after said pawl has been disengaged therefrom.
Claim 6
Dependent Claim
27 words
A power supply for generating an electrical pulse as in claim 1 including visual indication means for determining the wound or unwound state of said coil spring.
Claim 7
Dependent Claim
65 words
A power supply for generating an electric pulse according to claim 1 including circuit means connected to said coil including means of storing at least a portion of the energy induced in said coil when said magnetic member is rotated relative to said coil and including time delay means for releasing at least a portion of said energy at at least one preselected time interval.
Claim 8
Dependent Claim
42 words
A power supply for generating an electrical pulse according to claim 1 including remotely controllable pyrotechnic piston means supported to said housing and having connection with the release pawl, said pyrotechnic means functioning as said means to operably release said release pawl.
