Abstract
Abstract A firing control apparatus for teleguided missiles comprising an assembly of a periscopic sighting telescope and an infra-red goniometer adapted to locate, with respect to the sighting axis of a target, a missile emitting infra-red radiation, and to determine its errors of trajectory with respect to the sighting axis, and an associated teleguiding system giving orders at every instant so as to correct the errors measured by the infra-red goniometer. The whole assembly is fixed in one casing having a support permitting pivotal movement of the combined sighting telescope and goniometer about two perpendicular axes, one of which passes through the center of gravity of the apparatus, the optical axes of the telescope and the goniometer constituting two parallel optical paths.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A firing control apparatus for locating a missile emitting infra-red radiation with respect to the sighting axis of a target, in order to determine its errors of trajectory with respect to said sighting axis, which apparatus is associated with a guidance system enabling said errors to be annulled at any instant comprising a rigid casing; a periscopic optical sighting means in said casing disposed to receive and transmit an optical image of the target through the exit aperture thereof; an infra-red detection means to receive the infra-red radiation and transmit transduced electrical intelligence signals to the guidance system, said detection means being a goniometer rigidly fixed to said casing; said periscopic optical sighting means and said infra-red detection means being disposed for operation in parallel paths relative to each other for sighting and detecting respectively; a supporting means attached to said casing for support of said casing to permit a pivotal movement of said sighting and detection means with respect to two perpendicular axes of which at least one passes through the center of gravity of the firing control apparatus.
Claim 2
Dependent Claim
180 words
A firing control apparatus for locating a missile emitting infra-red radiation with respect to the sighting axis of a target, in order to determine its errors of trajectory with respect to said sighting axis, which apparatus is associated with a guidance system enabling said errors to be annulled at any instant comprising a rigid casing; a periscopic optical sighting means in said casing disposed to receive and transmit an optical image of the target through the exit aperture thereof; an infra-red detection means to receive the infra-red radiation and transmit transduced electrical intelligence signals to the guidance system, said detection means being a goniometer rigidly fixed to said casing; said periscopic optical sighting means and said infra-red detection means being disposed for operation in parallel paths relative to each other for sighting and detecting respectively; a supporting means attached to said casing for support of said casing to permit a pivotal movement of said sighting and detection means with respect to two perpendicular axes of which at least one passes through the center of gravity of the firing control apparatus.
Claim 3
Dependent Claim
75 words
The firing control apparatus of claim 1, further characterized by said sighting means being a periscopic telescope having a head mirror; said infra-red goniometer detection means being rigidly mounted to said periscopic telescope in adjacency to said head mirror; said supporting means including swivel joint means for the attachment of said casing to a fixed frame at the level of the center of gravity of the firing control apparatus; and means to pivot said casing.
Claim 4
Dependent Claim
101 words
The firing control apparatus of claim 1, further characterized by said sighting means being a periscopic telescope having a head mirror; said infra-red goniometer detection means being mounted in optical communication with the interior of said case and disposed to intercept reflected rays along the path of the bundle of rays reflected from said head mirror of said periscopic telescope; said head mirror having a mounting means which is pivotal about a horizontal axis; and means connectable to a fixed frame to permit rotation of said casing about a vertical axis passing through the center of gravity of said control apparatus.
Claim 5
Dependent Claim
46 words
The firing control apparatus of claim 3, further characterized by said infra-red goniometer detection means being mounted adjacent the exit aperture of the case along the path of rays from said periscopic telescope and receiving rays reflected in a path parallel with said bundle of rays.
Claim 6
Dependent Claim
30 words
The firing control apparatus of claim 1, further characterized by said supporting means including friction damping means comprising nylon discs to damp movements of said casing in elevation and azimuth.
Claim 7
Dependent Claim
33 words
The firing control apparatus of claim 1, further characterized by said supporting means including friction damping means comprising metallic discs immersed in oil to damp movements of said casing in elevation and azimuth.
