Patent number: 8017090Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.Type: GrantFiled: May 21, 2009Date of Patent: September 13, 2011Assignee: United Phosphorus Ltd.Inventors: Shroff Rajnikant Devidas, Pushpaksen P. Asher

Patent number: 6752943Abstract: Uniformly sized granules are formed using the present extruder and granulation process. The extruder contains a spiral worm screw for guiding a granulation material to an apertured plate. The spiral worm screw is rotated within a chamber and is formed from a guiding slant which terminates at a blunt edge near the apertured plate. The blunt edge rubs the granulation material against the apertured plate which softens the material foming a semi-solid material. The semi-solid material is then gently pushed through the apertured plate using just the required pressure. The granules are formed when the semi-solid material hardens after exiting the apertured plate.Type: GrantFiled: February 26, 2003Date of Patent: June 22, 2004Assignee: United Phosphorus, Ltd.Inventors: Prakash Mahadeo Jadhav, Jai Shroff
