Apparatus and method for dispensing incendiary spheres

1. An apparatus for dispensing incendiary spheres comprising:

a. a hopper operable to store discrete unitary unprimed spheres;

b. a feed mechanism cooperating with the hopper to extract unprimed spheres from the hopper;

c. a rotary sphere delivery mechanism rotating in a first direction and having at least one pocket defined therein, the at least one pocket being adapted to capture a sphere, wherein the feed mechanism cooperates with the rotary sphere delivery mechanism to load an unprimed sphere into the at least one pocket;

d. a rotary injector mechanism rotating in an opposing second direction and having at least one injector needle, wherein the rotary injector mechanism and the rotary sphere delivery mechanism are synchronized such that the at least one injector needle pierces an unprimed sphere within the at least one pocket as the at least one pocket and the at least one injector needle rotate past each other;

e. a source of reactant in fluid communication with the at least one injector needle, wherein the rotary injector mechanism delivers an amount of reactant to the at least one injector upon the at least one injector piercing the sphere to start a delayed exothermic reaction within the sphere thereby priming the sphere; and

f. a motor to drive the rotary sphere delivery mechanism and the rotary injector mechanism.

2. The apparatus as claimed in claim 1 further comprising a sphere expulsion mechanism operable to expel the primed sphere from the apparatus so that the primed sphere may fall away from the apparatus.

3. The apparatus as claimed in claim 2 wherein the at least one injector needle is operable to withdraw the primed sphere from the at least one pocket as the at least one pocket and the at least one injector needle rotate away from each other, and the sphere expulsion mechanism comprises a ramp surface against which the primed sphere abuts after withdrawal from the at least one pocket, the ramp surface being configured to cause a release of the primed sphere from the at least one injector needle.

4. The apparatus as claimed in claim 2 further comprising a stripping mechanism cooperating with the rotary sphere delivery mechanism to clear a sphere, or debris in the event of a broken sphere, left in the at least one pocket after the sphere expulsion mechanism.

5. The apparatus as claimed in claim 1 wherein the feed mechanism comprises a rotary feed mechanism defining at least one second pocket adapted to capture a sphere from the hopper, wherein the rotary feed mechanism is synchronized with the rotary sphere delivery mechanism such that the at least one second pocket aligns with the at least one pocket on the rotary sphere delivery mechanism to deliver its sphere to the at least one pocket.

6. The apparatus as claimed in claim 5 wherein the motor drives the rotary feed mechanism, and wherein the rotary sphere delivery mechanism and the rotary injector mechanism are directly or indirectly geared to the rotary feed mechanism.

7. The apparatus as claimed in claim 6 further including a position sensor operable to provide information on the spatial position of any one or more of the at least one pocket, the at least one injector needle, and the at least one second pocket.

8. The apparatus as claimed in claim 7 further including a controller operable use the spatial position provide by the position sensor to stop the motor just after release of the primed sphere from the at least one pocket but before a next sphere is primed by the at least one injector needle.

9. The apparatus as claimed in claim 1 wherein the rotary injector mechanism includes a constant volume pump that is activated upon the at least one injector needle piercing the sphere to deliver a measured volume of reactant to the sphere.

10. The apparatus as claimed in claim 1 further comprising a support upon which the other structures are mounted, wherein the support includes suspension members to enable the apparatus to being suspended below an aircraft.

11. The apparatus as claimed in claim 1 further comprising a support upon which the other structures are mounted, wherein the support is adapted to being mounted in an aircraft in a manner that the primed spheres fall outside of the aircraft.
