Abstract: Rocket Accuracy Improvement Device, when coupled between the warhead and motor of a typical free flight rocket, isolates the warhead from the rocket motor in the axis using a plurality of ball bearings and thereby enables the warhead to spin independently of the motor. The separation of the warhead from the motor allows the angular momentum of the warhead, which has reached its maximum spin rate by the time the motor burns out, to act gyroscopically to maintain the trajectory of the rocket even when the motor reverses its spin, thus achieving a much more predictable flight path for the rocket.

Abstract: A stabilizer is disclosed, as for use at the intake to a fluid pump, comprising a tank for containing a reservoir of liquid for supplying the pump. Extending from and above the tank, a tube provides a dome to confine a volume of gas to dampen pulsations created by the pump. The gaseous phase (vapor) in the dome is maintained in the tank by a heater mounted on the dome in such a manner as to provide heat somewhat related to the need for increasing the volume of the gaseous phase. Increased heat transfer within the tank vaporizes liquid to increase the pressure of the gaseous phase resulting in an increase in volume.
