Publication number: 20120097607Abstract: Waste water conditioning has nearly 150 years of history. During this time, a method has developed that is considered to be state of the art. While this method meets the requirements at hand, it is complicated and expensive. The novel method breaks down the rigidly entrenched method and simplifies it. In a plurality of stages, the only energy that is used is gravity, which is readily available and free of cost. Thus, an “alternative sewage treatment plant” has been developed, which has a simpler method and is less expensive in terms of investment costs and operating costs, at the same capacity, and requires only a fraction of the previous required surface area. The most important characteristic of the invention is that the novel method separates solids from waste water immediately after entering the sewage treatment plant. Mechanically purified water is much faster, easier and less expensive to purify. The paths pursued for conditioning of the sludge are also new.Type: ApplicationFiled: January 15, 2010Publication date: April 26, 2012Inventor: Josef Merai

Publication number: 20100233307Abstract: In a resin granulating apparatus of the present invention, a bracket extending in the outward radial direction over an outer peripheral surface of a sleeve is provided for the sleeve for rotatably supporting a cutter shaft of a cutter for shearing a material extruded from a die. Stopper means cooperating with the bracket to regulate movement of the sleeve toward the die and moving a regulation position in the axial direction is provided on the radially outer side over an outer diameter of the sleeve. With such a configuration, installation space is compactified so as to additionally provide the stopper means in the existing facilities, and a position of the cutter relative to a die surface is precisely adjusted so as to stably produce a pellet of a best shape.Type: ApplicationFiled: March 5, 2010Publication date: September 16, 2010Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel Ltd.)Inventors: Keizo Arita, Yasuo Yoshii, Kazuo Iritani, Osamu Ikeda, Yoshiaki Nakata, Shin Iwasaki
