Abstract
A system for a self-ignitable secondary igniter. The system includes an outer wall extending for a length. The outer wall has a first end and a second end, and the outer wall is filled with a charge. The first end has a centralized-contact spring which is in contact with the outer wall. The centralized-contact spring has a recess and at least one leaf which contacts the outer wall. The system can further include an igniter coupled to the recess of the centralized-contact spring.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A system for a power charge, said system comprising:
an outer wall extending for a length, wherein said outer wall comprises a first end and a second end; wherein said outer wall is filled with a charge; wherein said first end comprises a centralized-contact spring; wherein said centralized-contact spring is in contact with said outer wall; and wherein said centralized-contact spring comprises a recess; and wherein said centralized-contact spring comprises at least one contact leaf.
2 . The system of claim 1 further comprising an self-ignitable secondary igniter coupled with said recess.
3 . The system of claim 1 wherein said igniter comprises a resistor or several resistors.
4 . The system of claim 1 wherein said igniter is self-ignitable.
5 . The system of claim 2 wherein the secondary igniter is casted in a metal cup.
6 . The system of claim 5 wherein said cup has a bottom, wherein the bottom of said cup allows a flame to travel once set.
7 . The system of claim 6 further comprising a resistor, and wherein said resistor is electrically coupled to said cup.
8 . The system of claim 7 wherein the secondary igniter is inserted into said centralized spring.
9 . The system of claim 8 wherein contact between the centralized spring to the wall of the chamber creates ground for firing.Join the waitlist — get patent alerts
