Publication number: 20040168990Abstract: A method of and arrangement for continuous hydrolysis of organic material in the form of sludge with a dry solids content of 1-20% are described. The method includes the following steps: (a) heating a sludge containing the organic material with a low content of abrasive components and a dry solids content of 1-20%, to a temperature of approximately 100° C.; (b) mixing the sludge with steam at a pressure of 1-4 bar a; (c) leading the sludge/steam mixture to a preheating tank (4); (d) increasing the pressure of the sludge/steam mixture from 3 to 10 bar a; (e) leading the sludge/steam mixture to a reactor (7); (e) depressurising the sludge/steam mixture to 1-4 bar a in a depressurising tank (10); (f) separating sludge and steam, and possibly (g) cooling the sludge further.Type: ApplicationFiled: March 9, 2004Publication date: September 2, 2004Inventor: Odd Egil Solheim

Publication number: 20040168991Abstract: The invention relates to a method of clarifying and/or thickening a solution containing solids i.e. a slurry, and the apparatus for accomplishing this. Using the method and apparatus of the present invention, the slurry to be fed into the clarification or thickening apparatus is distributed evenly into the slurry already in the tank. It is characteristic of the clarification tank now developed that the displacement capacity of the raking system in the tank is the same from the edges of the tank up to the centre. The displacement capacity is measured as being the same as the underflow discharge capacity from the centre of the tank. The displacement capacity can be determined to be the same using rake displacement plates of different heights, according to the distance of the displacement plates from the rake shaft and the number of plates rotating on the same ring-like cross-section.Type: ApplicationFiled: December 19, 2003Publication date: September 2, 2004Inventors: Bror Nyman, Matti Nuorala

Publication number: 20040168992Abstract: A water recycling solution for gray water is provided, which may include upper and lower water tanks placed at high and low points, respectively, of for example a building or residence. Piping and valves (which may be low pressure) may be incorporated to enable efficient low-pressure water flow throughout the system. Mechanical filters and/or traps, colorants and anti-bacterial chemicals etc. may be utilized to, for example, prevent clogging and reduce contaminants within the gray water utilized.Type: ApplicationFiled: December 15, 2003Publication date: September 2, 2004Inventor: Ori Ben-Amotz

Publication number: 20040168993Abstract: A mail case system includes facilitates sequence-sorting various types of mail together into individual bags that each represent unique delivery points. The mail case uses multi-bag inserts so that the bags for several stops can be set up quickly for sorting. At the end of the sorting operation, the entire insert may be pulled down from the case as a single unit to maintain the established delivery point sequence. This eliminates the carrier's need to find separation points or to combine selections from multiple sequenced stacks of mail during the delivery operation. This results in a dramatic improvement in delivery efficiency.Type: ApplicationFiled: February 27, 2004Publication date: September 2, 2004Inventors: James M. Pippin, Gerald A. Isaacs, Floyd W. Worth
