Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
A delayed action control switch mechanism for a missile which impacts a target area comprising, a. an elongated member including an internal conductor coextensive with and residing therein, b. terminal means at the end of said conductors and defining a gap therebetween, c. a resistive element connected to said terminals across said gap and disposed to rupture after a time lag from the time of said impact, and d. means connected to said resistive element to cause the detonation of said explosive charge upon the rupture thereof.
Claim 2
Dependent Claim
87 words
A delayed action control switch mechanism for a missile which impacts a target area comprising, a. an elongated member including an internal conductor coextensive with and residing therein, b. terminal means at the end of said conductors and defining a gap therebetween, c. a resistive element connected to said terminals across said gap and disposed to rupture after a time lag from the time of said impact, and d. means connected to said resistive element to cause the detonation of said explosive charge upon the rupture thereof.
Claim 3
Dependent Claim
31 words
A control switch mechanism according to claim 1 and wherein said elongated member is a single continuous ring and said terminal means include axially extended terminals for supporting said resistive elements.
Claim 4
Dependent Claim
31 words
A control switch mechanism according to claim 1 and wherein said elongated member includes a plurality of segmented members connected to form a single ring with gaps between said segmented parts.
