Patent number: 4995765Abstract: A sanitary waste collection system and a method therefor which enable the free disposal of waste at various places in a building, and saves labor required for carrying and collecting the waste. The waste collection system includes charge ports provided at every floor of the building into which are thrown waste stored in waste containers of a certain configuration, vertical transport tubes connected to each floor of the building as well as charge ports, horizontal transport tubes connected to the lower ends of the vertical transport tubes and extending to a waste accumulation area, and an air blowing mechanism for force-feeding air in the horizontal transport tubes, with the diameters of the vertical and horizontal transport tubes and being a little larger than the outer diameter of the waste container in section.Type: GrantFiled: April 18, 1988Date of Patent: February 26, 1991Assignees: Shimizu Construction Co., Ltd., Shinmeiwa Industry Co., Ltd.Inventors: Tomoya Tokuhiro, Nobutaka Koibuchi, Teruhiko Miyauchi, Koshin Kikuchi, Jun Hirokawa, Kunio Yamashiro, Sakae Nishizuka, Ippei Watanabe, Shozo Maruo, Yohichiro Tsutsui, Sadahito Ishikawa

Patent number: 4993882Abstract: This invention relates to a waste collecting method which is sanitary and in which throwing-away of waste at each location within a building can be carried out freely and without waiting time, and labors required for transporting or collecting the waste can be reduced. The waste collecting method essentially consists of operating one of a plurality of throwing devices (3) arranged respectively at a plurality of floors of a building, the one throwing device (3) having accommodated therein waste containers (2), and throwing the waste containers (2) into a vertical transport pipe (4) mounted to the building in such a fashion so as to prevent clogging of the vertical transport pipe (4), and the further step of decelerating the falling waste containers (2) at a lower portion of the vertical transport pipe (4) so as to prevent the thrown-in waste containers (2) from being broken when they reach a shut-off valve provided at a lower end of the vertical transport pipe (4).Type: GrantFiled: April 18, 1988Date of Patent: February 19, 1991Assignees: Shimizu Construction Co., Ltd., Shinmeiwa Industry Co., Ltd.Inventors: Sakae Nishizuka, Ippei Watanabe, Shozo Maruo, Yohichiro Tsutsui, Sadahito Ishikawa, Nobutaka Koibuchi, Teruhiko Miyauchi, Koshin Kikuchi

Patent number: 4247229Abstract: An underground mining method and apparatus which utilizes at least first and second spaced-apart shafts extending essentially downwardly into the earth and at least one lateral opening connecting the two shafts at a location below the earth's surface. An empty ore carrier is dropped into a first of said shafts and allowed to gravitationally fall towards the bottom of said shaft, its rate of descent being controlled by regulating the flow of air out of the bottom of said shaft. When the empty ore carrier reaches its stopping point in the first shaft, the carrier is transferred into the lateral opening filled with ore, then into a watertight compartment which is sealed and filled with water, and then into the second water-filled shaft. The ore-bearing carrier then floats to the earth's surface, is emptied, and returned empty to the first shaft for a repeat of the above procedure. Several carriers are kept in service at the same time.Type: GrantFiled: February 25, 1980Date of Patent: January 27, 1981Assignee: Atlantic Richfield CompanyInventor: Hugh W. Evans
