Abstract: PRESSURE DISSIPATION APPARATUS Abstract Apparatus for dissipating the pressure of a confined fluid has a housing with a sidewall in a substantially circular cross-sectional configuration with a top and bottom.  Inlet means is formed into the sidewall so that the axis of the inlet is tangent to a diameter of the sidewall. An outlet extends through the bottom and an opening extends through the top.  High pressure fluids entering the inlet form a vortex around the sidewall and between the top and the bottom and pass out the outlet under low pressure.  Air is introduced through the openings in the top to prevent cavitation within the housing.  A device may be coupled to the outlet to reduce the velocity of the fluids leaving the outlet.

Abstract: ABSTRACT         An optical system having a dual field of view.  The system  includes  a  wide-angle  objective  comprising  a  lens,  a concave primary mirror,  and a movable convex secondary mirror having a first position and a second position.  When in the first position, the secondary mirror permits the wide-angle objective to focus radiation.  When in the second position, the secondary mirror prevents radiation from being focused by the wide-angle objective.  The combination of the secondary mirror when in the second position and the primary mirror comprise a narrow-angle objective with the primary mirror converging radiation to the secondary mirror and  the secondary mirror  focusing radiation.          Thus, the optical system has a wide-angle field of view whenever the secondary mirror is in the first position and a narrow-angle field of view whenever  the secondary mirror  is in the second position.
