Abstract: A system for ejecting a missile from a submerged vessel includes: a tube for housing the missile; a tank for storing atmospheric gas as a pressurized liquid, whereby a valve is connected to the tank to allow release of the gas into the tube to eject the missile from the tube; and a microwave emitter located within the liquid in the tank to input heat energy into the liquid to maintain evaporation of the liquid into the gas, whereby the microwave emitter is activated simultaneously with the release of the gas into the tube.

Abstract: An apparatus as a fixture for fluidly pressure testing a flange penetrator seal with the apparatus having a flange cover including a recess and a flange extension including a recess with the extension matable to the cover such that the recesses create a volume around the seal. The extension is secured to the flange of a device for which the flange penetrator seal supports. The cover has a pressure fitting for application of fluid pressure to the recess of the cover for pressure testing the seal within the volume and the extension having a fitting for draining the volume after testing is complete. The test fixture includes a clamping fixture attachable to the cover, the clamping fixture encompassing the flange cover and the extension such that the apparatus can be further secured to the flange of the device which the flange penetrator seal supports.
