Abstract

An electric primer for the discharge of small arms ammunition including a conductive cup (10), an aperture (12) formed in the cup bottom (11), a conductive explosive (13), a conductive contact (14), a nipple portion (15), and an insulating liner (16).

Claims

AMENDED CLAIMS[received by the International Bureau on 11 June 1999 (11.06.99); original claims 12, 19, 25-28 and 30-33 amended; remaining claims unchanged (4 pages)]
1. An electric primer for small arms ammmiition comprising:
(a) an electrically conductive cup having an open top and a bottom having an aperture formed in the bottom;
(b) an electrically insulating liner within the cup, the liner foπned from at least one polymeric material having an Impact Toughness of at least about 1 ft-lb/in, a Heat Distortion Temperature at 264 psi stress of at least about 175°F, and a Modulus of Elasticity of at least about 130,000 psi; (c) at least one electrically conductive explosive composition within the insulating liner and the cup;
(d) an electrically conductive contact positioned between the explosive and the bottom of the cup, the contact having a portion extending toward the aperture in the bottom of the cup; and (e) a retaining means on top of the explosive; wherein the liner is positioned to electrically insulate the cup from the contact, and wherein the liner has at least one means for retaining the electrically conductive contact within the cup after discharge of the explosive.
2. An electric primer of Claim 1 wherein the retaining means comprises a foil.
3. An electric primer of Claim 2 wherein the foil consists essentially of metal.
4. An electric primer of Claim 1 wherein the retaining means consists essentially of lacquer.
5 An electric primer of Claim 2 wherein the retaining means further comprises a lacquer.
6. An electric primer of Claim 4 wherein the lacquer comprises at least about 0.5% by weight of carbon fiber.
7. An electric primer of Claim 3 wherein the retaining means further comprises a lacquer having at least about 0.5% by weight of carbon fiber.
8. An electric primer of Claim 3 wherein the configuration of the explosive and the retaining foil provide a substantially uniform distance between any point on the electrically conductive contact and the foil.
9 An electric primer of Claim 2 wherein the retaining means further comprises an anvil press fit into the cup on top of the foil.
10. An electric primer of Claim 3 wherein the retaining means further comprises a conductive retainer press fit into the cup on top of the foil.
11. An electric primer of Claim 1 wherein the insulating liner comprises poly(ether ether ketone).
12 An electric primer of Claim 1 wherein the poly(ether ether ketone) is substantially amorphous.
13. An electric primer of Claim 1 wherein the insulating liner comprises adhesive.
14. An electric primer of Claim 1 wherein the insulator has an inner surface and projections formed thereon positioned to retain the contact within the cup after discharge of the explosive.
15. An electric primer of Claim 1 wherein the insulator has a mouth inwardly formed to retain the contact within the cup after discharge of the explosive.
16. An electric primer of Claim 1 wherein the insulating liner extends into the aperture in the bottom of the cup.
17. An electric primer of Claim 3 wherein the retaining foil is perforated.
18. An electric primer of Claim 3 wherein the side walls of the insulator extend to the retaining means and the metal foil is in contact with the side walls of the cup.
19. An electric primer of Claim 17 wherein the retaining foil is perforated.
20. An electric primer of Claim 1 wherein the insulating liner further comprises conductive filler having a resistivity of at least about 100 ohm-cm.
21. An electric primer of Claim 17 wherein the retainer further comprises a conductive anvil on top of the metal foil.
22. An electric primer of Claim 17 wherein the conductive foil is perforated.
23. An electric primer of Claim 10 wherein the retaining means further comprises lacquer.
24. An electric primer for small arms ammunition comprising:
(a) an electrically conductive cup having a top and a bottom having an aperture formed in the bottom;
(b) at least one electrically conductive explosive composition within the cup;
(c) a disc in the bottom of the cup, the disc comprising top and bottom surfaces and a central conductive portion adjacent the aperture in the bottom of the cup, the central conductive portion having conductive surfaces on the top and bottom of the disc, and wherein at least the conductive surface on the bottom of the disc is smaller in diameter than the aperture, the disc further comprising an annular portion of electrically insulating material separating the cup from the central conductive portion; and
(d) a retaining means on top of the explosive.
25. An electric primer of Claim 24 wherein the retaining means comprises a foil.
26. An electric primer of Claim 25 wherein the foil consists essentially of metal.
27. An electric primer of Claim 24 wherein the retaining means consists essentially of lacquer.
28. An electric primer of Claim 25 wherein the retaining means further comprises a lacquer.
29. An electric primer of Claim 24 wherein the lacquer comprises at least about 0.5% by weight of carbon fiber.
30. An electric primer of Claim 25 wherein the retaining means further comprises a lacquer having at least about 0.5% by weight of carbon fiber.
31. An electric primer of Claim 25 wherein the retaining means further comprises an anvil press fit into the cup on top of the foil.
32. An electric primer of Claim 25 wherein the retaining means further comprises a conductive retainer press fit into the cup on top of the foil.
33. An electric primer of Claim 25 wherein the retaining foil is perforated.
STATEMENT UNDER ARTICLE 19
Retyped pages embodying the above changes are submitted herewith.
The applicant respectfully traverses the conclusion that the documents cited in the International search Report indicated in Catagories "X" and "Y" disclose subject matter such that the claimed invention cannot be considered novel or cannot be considered to involve an inventive step when the documents are taken alone or and in combination with one or more other such documents. Specifically, none of the cited documents discloses or suggests the invention as presently claimed, that is, an electric primer for small arms ammunition having an electrically insulating liner within the cup formed from at least one polymeric material having the Impact Toughness, Heat Distortion Temperature, and Modulus Elasticity as presently required. As noted in the present specification, the properties as defined are particularly characterized by poly(ether ether ketones). In view of these considerations, the present claims, as amended, are considered to define a novel and inventive step.
