Patent CA-1061922-A (CA)
Inventor: SUH NAM P
IPC: C08K9/00

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to fiber reinforced plastic com-posites, and more particularly, composites having substantially improved fracture toughness at high speed loading. In accordance with this invention, the fracture toughness of a composite is substantially improved by the use of an internal energy damping mechanism which is dependent upon the rate of loading.  This energy dumping mechanism comprises fibers dis-persed through the composite pre-coated with a viscous fluid. Upon impact, substantial energy is dissipated at the fiber-matrix interface due to shear deformation of the coated viscous layer.  The composites of this invention can be used in any environment where it is desired to absorb impact energy while minimizing or eliminating the threat of composite fracture such as in highway guard rails, machinery housings or protective helmets.

Abstract: AUGMENTED PERSPECTIVE RADAR DISPLAY              ABSTRACT         Control circuits are provided in a perspective radar display to modify the vertical sweep wave form voltage function on the display cathode ray tube to correspond to the sweep function which would be provided if the observer and radar antenna were at a different position from the actual position.  This different position may constitute a different altitude or a different range or a combination of both.  If the perspective display is used in an aircraft flying at, for example, 100 feet, the pilot can modify the display to provide a perspective radar image as would appear if the aircraft were at an altitude, for example, of 500 feet or 5,000 feet thereby rendering more easily distinguish-able distant objects close to the horizon.  Alternatively or in combination with a simulated or augmented altitude, the pilot can effectively modify the display to effectively provide a display which would occur at an increased range from targets so that close in targets are rendered visible.          The same principles are applicable to boats and ships.

Abstract: ABSTRACT OF THE DISCLOSURE            A cooling device for use in the quenching of com-bustion gases containing hydrogen chloride.  The entire quenching zone is lined with acidproof material as a safeguard against the occurrence of temperatures lower than the dew point, wherever they may occur inside the quenching zone.  This temperature sen-sitive lining of the quenching zone is protected against the action of the hot combustion gases by a covering above the quenching liquid feed inlet, of heat-retaining bricks of differing thicknesses, which absorb and buffer the heat con-tained in the hot combustion gases.  Further, the quenching zone is equipped, in its upper third portion, with 3 to 8 nozzle structures for the intake of cooling and absorbing liquid, which ensure the intake of such liquid in the quantity necessary for the rapid and complete quenching of the hot reaction gases.  Such a cooling device, is very suitable for use in the quenching of hot, highly corrosive combustion gases containing hydrogen chloride, particularly those which are formed in the combustion of waste gases together with liquid residues, both the gases and the liquid residues containing one or more chlorinated hydrocarbons.
