Abstract: The present invention provides a molluscicide application apparatus and process that disperses the molluscicide below the water's surface in a manner that minimizes air entrainment and ensures that the molluscicide solution settles at the targeted floor of the body of water, such as a river or lake bed where driessenid mussels are concentrated, and do not rise to the water's surface or disperse. The present invention also maintains a desired viscosity level, for example, 180 centistokes, at typical freshwater temperatures varying from 15° C. to 25° C. by adjusting the flow rate and/or nozzle orifice area of the molluscicide application.

Abstract: A solid state ignition safety device for rocket assisted projectiles having a piezoelectric generator that charges a capacitor during the initial acceleration of the projectile by the launching propellant charge. The capacitor is then discharged after a delay to ignite an initiator, which ignites the rocket motor of the projectile. A time delay circuit can be integrated into the ignition safety device to further delay the ignition of the initiator until the projectile has reached the ideal point in its trajectory to ignite the rocket motor.
