Patent number: 7530511Abstract: The present invention is a high pressure homogenizing apparatus and a method for dividing a fine solid material or fibrous cellulose of chemical, medical, and resin products in suspension as a dispersion or emulsification, or dividing by crushing cell membranes of fungi with high efficiency. The apparatus is free from valve damages to simplify maintenance and control. The high pressure homogenizing apparatus to finely divide a raw material in suspension includes a high pressure homogenizing device having an orifice, a raw material receiving passage connected to the high pressure homogenizing device, a processing piston, and a processing recess disposed in a receiver. A front end of the processing piston is inserted into the processing recess with a pressure intensifier and a volume compression inside the processing recess pressurizes the suspension in the processing recess to lead the suspension into the raw material receiving passage for dividing the raw material.Type: GrantFiled: July 7, 2005Date of Patent: May 12, 2009Inventors: Shigeo Ando, Masao Ando, Toyoroku Ando

Patent number: 7527008Abstract: The invention provides for a novel apparatus and a method to effectively manage ballast material. It comprises of a plurality of Floating Ballast Containers (25) contained within a bottomless enclosure and secured on the sea faring vessel such that each floating ballast container (25) floats in seawater. The volumetric capacity of the conventional segregated ballast tanks (30) on the sea faring vessel is similar to that of the Floating Ballast Containers (25) so as to facilitate the movement of the ballast material between the conventional ballast tanks (30) and Floating Ballast Containers (25). This process eliminates the need for treatment or disposal of the ballast material in to the sea.Type: GrantFiled: September 23, 2003Date of Patent: May 5, 2009Inventor: Virendra J Mehta

Patent number: 7442240Abstract: An alkoxylpropyl isothiazolinone of formula: C6H6Cl2NO2SR, in which R is CH3, CH2CH3, CH(CH3)2, CH2CH2CH2CH3, CH2CH2OCH3 or CH2CH2OC6H5Cl. A method for preparing the isothiazolinone by reacting sodium polysulphide with methyl acrylate to obtain dimethyl dithiodipropionate, followed by aminolysis with alkoxyl propylamine to obtain N,N?-dialkoxylpropyldithio-dipropionamide, which is then reacted with sulfuric chloride. The alkoxylpropyl-isothiazolinone of the invention can be used for preparing marine antifouling paint coating as antifoulant, and also used as bactericide.Type: GrantFiled: September 30, 2005Date of Patent: October 28, 2008Assignee: Ocean University of ChinaInventors: Liangmin Yu, Xiaohui Jiang, Zhiming Zhang, Huanzhi Xu, Changcheng Li

Patent number: 7338045Abstract: A three-dimensional maze game in the form of a hand-held toy. The hand held toy is in the form of a cube. The toy comprises a substantially cubic non-transparent body containing a plurality of intersecting pathways for an object and an entrance aperture and single/multiple exit apertures connecting the pathways wherein each intersection formed by the intersecting pathways is provided with means to bring the object to rest till the toy is tilted and the object follows a vertical pathway that is defined by the tilting of the toy. The object is inserted into an entry point in the toy and the player has to bring the object out through an exit point by following a fixed number of steps in turning the toy. The challenge is to find the correct sequence of turns and considerable amount of mental dexterity is required for the purpose.Type: GrantFiled: November 4, 2003Date of Patent: March 4, 2008Inventor: Dwipendra Nath Guha

Patent number: 7296586Abstract: A gas-regulating unit for regulating an internal gas pressure in a gas-tight liquid-storage tank is mounted on the gas-tight tank in which stored liquid is sealed from outside atmosphere by covering a top surface of the stored liquid with an isolating-gas. The gas-regulating unit includes a main gas-exhausting unit and an isolating-gas regulator. The main gas-exhausting unit includes an exhaust valve for opening and exhausting gases from the gas-tight tank when an internal gas pressure in the gas-tight tank increases to more than a specified level. The isolating-gas regulator supplies the isolating-gas when an isolating-gas pressure decreases to less than a specified level. The main gas-exhausting unit and the isolating-gas regulator are integrally coupled with each other.Type: GrantFiled: April 26, 2005Date of Patent: November 20, 2007Assignee: Kaneko Sangyo Co., Ltd.Inventor: Hideto Hosoda
