Models of the Chaipattana Aerator
Model A: Water spraying buckets are rotated by the transmitting power system, using both roller chain and chain sprocket, together with 1:50 reduction gear attached to a two-horsepower electric motor.
Model B: Water spraying buckets are rotated by the transmitting power system using 1:300, two-horsepower electric reduction gear motor, driving on one side.
Model C: Similar in feature to Model A, but different in application in that it is not stationary but mobile, this model is used in case of no accessible electric power in the water source. It is driven by gasoline engine and the direction is controlled by an attendant.
Model D: Water spraying buckets are rotated by 1:50 reduction gear motor, together with 1:6 reduction spur gear, two-horsepower electric motor.
Patent
It is an overwhelming joy for all Thais upon learning that the Chaipattana Aerator has been considered and received a patent in His Majesty the King’s name on February 2, 1993. The aerator is the world’s ninth mechanical aeration device to be patented and the first to be registered as well issued a patent to a Monarch. This patent signifies His Majesty the King as “the first Monarch in the Thai and world history to receive a patent.”
Awards of Honour
The Chaipattana Aerator became famous once again when the Office of the National Research Council bestowed upon His Majesty the King the First Prize Award in the category of creative work of invention for the benefit of the nation for the year 1993. The Council also praised His Majesty’s ingenuity in creating an aerator which effectively treats waste water.
Moreover, the cabinet issued a resolution to declare the 2nd of February of each year as “Inventor’s Day,” to honour the day on which His Majesty received the patent, that is February 2, 1993.
For the international awards of honour, the Belgian Chamber of Inventor, which is Europe’s oldest organization of invention, organized the Brussels Eureka 2000: the 49th Anniversary of the World Exhibition of Innovation, Research and New Technology between November 14-20, 2000, in Brussels, Belgium.
The International Committee announced during the Award Presentation Ceremony before researchers, inventors, and other guests that
“The various awards presented today are granted after a careful consideration. The invention of every field must be able to apply to a wide use as well as contribute to developing the quality of life and the global environment. The Chaipattana Low Speed Surface Aerator, Model RX-2 is therefore praiseworthy as the outstanding invention for this ceremony.”
Furthermore, the International Committee praised His Majesty the King as follows:
