Abstract: This patent describes technology for generating ammonia from urea. The method is based on the hydrolysis of an aqueous solution of urea and/or biuret by heating under pressure to form a mixture of ammonia, carbon dioxide and water. The gas mixtures produced are useful for supplying ammonia at controlled pressure and rate of flow for many industrial applications without the risks and hazards associated with the transportation and on-site storage of ammonia, thereby providing a significant safety advantage over present industrial practice.

Abstract: A line of illuminated electrically powered exit indicators, each having a power backup is mounted on one surface of a non-conductive tape-like support which is flexible enough to be formed into a roll and bend around corners. The exit indicators and the electric circuits are mounted on one surface of the support. A strong adhesive is applied to the opposite surface of the support so that the exit indicators can be easily attached by the adhesive to surfaces of corridors. The tape-like support is provided with a device which permits the tape-like support to be easily unrolled without stressing the electric circuits on the surface of the tape-like support roll.

Abstract: A process to provide a pressurized gas stream useful for removing nitrogen oxides from a combustion gas stream by hydrolyzing urea in aqueous solution in a closed reactor to evolve gaseous ammonia at a rate essentially balanced to the amount required from the combustion gas stream. The improvement resides in maintaining the pressure in the reactor within a preselected range when the demand for ammonia for external use suddenly drops by cooling the solution within the hydrolysis reactor by heat exchange either within or external to the reactor in response to rapid changes in demand for ammonia required to remove said nitrogen oxides.

Abstract: The novel compound 3,3-Dinitro-4,4′-hydrozofurazan and the methods of preparation. The method of preparation 3,3-Dinitro-4,4′-hydrazofurazan which comprises partially reducing 3,3′-Dinitro-4,4′-azoxyfurazan. The method of preparing 3,3′-Dinitro-4,4′-hydrazofurazan by the partial reduction of 3,3′-Dinitro-4,4′-azofurazan.

Abstract: An inflatable boat adapted to serve as a training aid and enable a towable personal hydrofoil watersport device adapted to carry a seated rider having an elongate board and a vertical strut extending generally at a right angle to said board to float on the surface of the water comprising: (a) elongated spaced apart inflatable pontoon sections connected in proximity to their lower extremities by (b) a carrying surface, said pontoon sections and carrying surface forming a generally smooth leading surface for being towed through water with minimum drag, said carrying surface being provided with an opening in proximity to its trailing edge, said opening being adapted to retain said boat and the lateral distance between said pontoon sections being adapted to receive the elongated board of a water sport device adapted to carry a seated rider.

Abstract: The patent describes a power boat having a transom and a swim platform or step generally projecting from the transom at a right angle at or near the water line. The swim step is adapted to the launching of a seated rider carried on a sky ski having an elongated board and a tee bar normally extending from the board into the water. The swim platform has a slot adapted to receive tee bar and extends from the port and/or starboard margins and runs generally parallel to the transom to an extent sufficient to snugly receive the tee bar while the board is supported by the platform with the tee bar extending through the slot and below the platform into the water whereby a rider can mount the seat and secure himself to the sky ski and then readily launch himself and the ski by pushing out of the slot.
