  • Patent number: 4653674
    Abstract: A goods dispensing device including an annular dispensing port formed in a container, an annular shelf located in a position for receiving the goods released through the annular dispensing port, a table rotatably supported in a position for receiving the goods flowing downwardly from the shelf, a ring located along the shelf for rotation independently of the table, a rotary drive unit connected to the table through motive force transmitting mechanism, a rotary drive unit connected to the ring through motive force transmitting mechanism, scrapers fixedly supported on the ring and projecting above the shelf, a guide scraper fixedly supported and projecting above the table, and a goods conveyor arranged below the guide scraper for conveying the goods dispensed from the container through the annular dispensing port. There is a relative difference between the rotary movements of the scraper rotating with the ring as a unit and the table.

  • Patent number: 4628616
    Abstract: A vapor tank for processing a product by heating the same through exposure to vapor serving as a heat transfer medium. The vapor tank includes at least one partition wall separating a vapor chamber filled with vapor and a heating chamber for processing the product by heating the same for supplying a sufficient saturated vapor to the product. The partition wall is formed with openings for allowing the saturated vapor to be injected therethrough from the vapor chamber into the heating chamber where the product is enveloped by the saturated vapor. The vapor tank is provided with a recovery device for recovering the vapor flowing out of the tank through an inlet and an outlet for introducing and discharging the product into and out of the tank with a high degree of vapor recovering efficiency and with a minimum loss of energy. The vapor tank is also provided with a mechanism for externally supplying air currents to prevent the vapor from flowing out of the tank through the inlet and the outlet.

  • Patent number: 3938912
    Abstract: There is disclosed a horizontal type hydrohoist, in which slurry is forced to feed under lower pressure into feed pipes which are connected to a transport pipeline at their one ends and to a high pressure clear water pump at the others, said pump being adapted to deliver clear water under a high pressure, after which clear water is transferred under a high pressure through said feed pipe from said high pressure clear water pump, thereby transferring said slurry. This hydrohoist system presents the provision of means for preventing mixing and its spreading at the boundary portion between slurry and water within the feed pipes. More particularly, a separator which is designed not to rotate during the transfer is inserted in the aforesaid boundary portion in a manner that the separator may be transferred together with fluid, thus preventing the mixing of water with slurry as well as the resultant spreading thereof.
