Abstract
Abstract In a reserve battery initiator a unitary moulded ampoule (10) containing an electrolyte comprises two portions conjoined by a mechanically weak section (11). The ampoule (10) may be ruptured by a striker (3) which is released when the initiator is subjected to sufficient an accelerative force to overcome a detent mechanism. The ampoule may also contain an insert (12) to transmit to the weak section the force imparted by the striker. The insert (12) may additionally have a cutting effect on the weak section (11 Conveniently the insert is in the form of a frustrum with a narrow end contiguous with the inner face of the ampoule at the location where the striker (3) impacts and a wide end contiguous with the inner face of the weak section (11).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
56 words
A reserve battery initiator comprising an ampoule (10) for containing an electrolyte, said ampoule having two portions, conjoined by a mechanically weak section (11), one portion being moveable relative to the other upon rupture of the weak section to release the electrolyte from the ampoule, characterised in that the ampoule (1) is moulded in one piece.
Claim 2
Dependent Claim
56 words
A reserve battery initiator comprising an ampoule (10) for containing an electrolyte, said ampoule having two portions, conjoined by a mechanically weak section (11), one portion being moveable relative to the other upon rupture of the weak section to release the electrolyte from the ampoule, characterised in that the ampoule (1) is moulded in one piece.
Claim 3
Dependent Claim
37 words
A reserve battery initiator according to claim 1 characterised in that there is further included a striker (3) arranged to impact with the ampoule (10) so as to rupture the ampoule at its mechanically weak section (1).
Claim 4
Dependent Claim
30 words
A reserve battery initiator according to claim 2 characterised in that the ampoule (10) contains an insert (12) which transmits to the weak section the force imparted by the striker.
Claim 5
Dependent Claim
55 words
A reserve battery initiator according to claim 3 characterised in that the insert (12) is in the form of a frustrum with a narrow end contiguous with the inner face of the ampoule at the location where the striker can impact, and a wide end contiguous with the inner face of the weak section (11).
Claim 6
Dependent Claim
33 words
A reserve battery initiator according to claim 3 or claim 4 characterised in that the insert (12) has a cutting effect on the said weak section when it impacts with the striker (3).
Claim 7
Dependent Claim
39 words
A reserve battery initiator according to claim 5 characerised in that the insert (12) has a plurality of. slots extending longitudinally from the wide end thereof so that the edges splay outwardly when the ampoule impacts with the striker.
Claim 8
Dependent Claim
34 words
A reserve battery initiator according to any one of claims 3 to 6 characterised in that the insert (12) is formed from a plastics material which is inert in the presence of the electrolyte.
Claim 9
Dependent Claim
30 words
A reserve battery initiator according to anyone preceding claim characterised in that the ampoule (10) is formed from a plastics material which is inert in the presence of the electrolyte.
Claim 10
Dependent Claim
45 words
A reserve battery initiator according to any one of claims 2 to 8 characterised in that there is included detent means for restraining the striker (3) and ampoule (10) from coming together until the initiator is subjected to a predetermined acceleration for a predetermined time.
Claim 11
Dependent Claim
93 words
A reserve battery initiator according to claim 9 characterised in that the detent means comprises a resiliently biased member (7) and at least one detent member (5), the resiliently biased member (7) normally holding each detent member (5) in a locking position in which it prevents contact between the striker (3) and the ampoule (1), and being moveable against its resilient bias on acceleration of the initiator of a predetermined magnitude and duration to release each detent Member (5) from its locking position so that the striker and the ampoule can impact together,
Claim 12
Dependent Claim
50 words
A reserve battery initiator according to claim 1 characterised in that one of the said two ampoule portions is of a sufficient mass that the inertia of the said portion causes the weak section (11) to rupture when the initiator is subjected to a predetermined acceleration for a predetermined time.
