P. G. Johansing, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transformation of halogenated refrigerant gases
    Patent number: 6110429
    Abstract: The high temperature combustion of hydrogen and oxygen is used to transform halogenated refrigerant gases (HRGs) and halons to produce calcium fluoride salts. Calcium carbonate is also produced by a series of chemical processes. Calcium chloride is partially consumed by the process by reaction with fluoride released during the high temperature combustion of the HRGs. Calcium chloride is also produced in the process during scrubbing of chlorine and during the recovery of ammonia used to remove carbon dioxide. The calcium chloride produced during the process can be used in the combustion reaction to further produce calcium fluoride.
    Type: Grant

  • Hydraulic fluid cooling system
    Patent number: 4363356
    Abstract: A system for operating a hydraulic tool is disclosed in which heated hydraulic fluid being returned to a fluid reservoir from the tool is cooled by a refrigeration system. The heated hydraulic fluid is introduced into the hollow interior of a distributor from which the fluid exits through a plurality of orifices in a planar side in the form of plural sprays directed onto adjacent portions of a coil carrying evaporating refrigerant. The sprays flow over the coil to effect substantial transfer of heat from the hydraulic fluid to the refrigerant, with the cooled hydraulic fluid being stored in the reservoir prior to being pumped to the hydraulic tool as needed.
