Baffle sections extend along a helical path over a central angle of at least about 360 degrees and are substantially continuously connected. At least some baffle sections following in circumferential direction along the silo wall are staggered with respect to each other increasing with the distance from the bottom. The baffle is preferably provided as a helical band. The pitch angle of the baffle relative to the cylindrical wall can be from about 15 to 30 degrees. A heating element can be provided to allow for heating of at least part of the baffle.Type: GrantFiled: August 24, 1982Date of Patent: July 30, 1985Assignee: Schwabische Huttenwerke GmbHInventor: Hans Gessler

Patent number: 4504182Abstract: A chip material container arrangement is provided for storage of material to be spread in the production of particle and/or fiber boards. The container arrangement is equipped with several discharge rollers arranged one above the other, a base belt and feeder devices. With a discharge opening extending over the width of the container, the density distribution of the material to be spread is controlled by removing appropriately dimensioned material quantities from individual partial streams which partial streams are later combined in the area of the discharge opening to form a total material flow.Type: GrantFiled: June 28, 1982Date of Patent: March 12, 1985Assignee: Carl Schenck AG.Inventor: Wolfgang Burkner

Patent number: 4464984Abstract: A plant for the preparation of fodder comprising a portion of solid foodstock in the form of grains or kernels and a portion of water. The plant includes a silo for the solid foodstock, a device for removing the solid foodstock from the silo, a conveying device for conveying the solid foodstock removed from the silo, a crushing mill which receives and crushes foodstock conveyed by the conveying device, and a mixing vessel for the mixing of the crushed solid foodstock and the water. A siphon is mounted between the conveying device and the crushing mill, the siphon being provided with water supply conduits at the inlet and outlet sides of the siphon.Type: GrantFiled: April 8, 1982Date of Patent: August 14, 1984Inventor: Hinrich A. Haake

Patent number: 4461606Abstract: A load supporting grid structure is disclosed for a bin or hopper having a discharger or reclaimer at the bottom. The grip structure is used when storing solid materials such as wood chips, hogged fuel and the like and reduces the weight of the solid materials on the discharger, particularly when the materials are stored at a depth of at least 20 feet. The grid structure is positioned above the discharger and supports the weight of at least a portion of the solid materials in the bin or hopper.Type: GrantFiled: July 21, 1983Date of Patent: July 24, 1984Assignee: S.W. Hooper & Co. Ltd.Inventor: Alexander D. Cormack

Patent number: 4431360Abstract: A container body for highway trailers, ships or aircraft, for loading and transporting goods provides a conveyor belt on the floor of the body with a vertical partition that is movable with the conveyor as the goods are loaded into, or removed from the body. The belt can be moved forwardly or backwardly by a transmission shaft and a separate portable, self-contained power source which can remain at a loading dock, thereby making it unnecessary to use the container vehicle's transport power source. An electrical control mechanism can be suitably connected to the container body at a loading dock to control operation of the conveyor belt because the portable power source, which may be an internal combustion engine provided with an electrically controlled reversing gearbox, also includes a battery and suitable connections to the container body to energize the control mechanism.Type: GrantFiled: July 22, 1981Date of Patent: February 14, 1984Inventor: Mamoru Maeno

Patent number: 4371306Abstract: Refuse compaction includes a storage body having an opening at one end for receiving refuse and having an opening at the other end. An ejection panel is movable in the storage body between the openings at the opposite ends. Hydraulic means including a cylinder, a piston and a support member are operatively coupled to the ejection panel for producing a movement of the ejection panel between the openings at the opposite ends of the storage body. Means are operatively coupled to the ejection panel, the support member and the hydraulic means for producing a pivotal movement of the support member and a displacement of the hydraulic means in the direction of movement of the ejection panel to minimize the displacement required between the cylinder and the piston for moving the ejection panel.Type: GrantFiled: February 23, 1981Date of Patent: February 1, 1983Assignee: Sargent Industries, Inc.Inventor: Fred T. Smith

Patent number: 4361254Abstract: A hopper includes a peripheral side wall having upper and lower open ends, and a conical body provided inside the peripheral side wall to define an annular space for storing solid material therebetween. The lower open end of the peripheral wall is separated from the conical body to define an annular discharge point therebetween.Type: GrantFiled: November 19, 1980Date of Patent: November 30, 1982Assignees: Hitachi Ltd., Ohbayashi-Gumi, Ltd.Inventors: Hiroshi Teraoku, Hideki Yamaguchi

Patent number: 4350468Abstract: A high-rise silo in which silage is fed radially by means of revolving feed members to a central vertical clearing shaft of the silo. The silage is withdrawn from the shaft at the bottom. The shaft itself is assembled from separate cylindrical pipe lengths each of which has an internal encircling groove with a sealing ring at the upper end, into which engages an internal co-axial annular flange situated at the lower end of the superjacent cylindrical pipe length, in sealing manner.Type: GrantFiled: January 5, 1981Date of Patent: September 21, 1982Assignee: Engelbrecht & Lemmerbrock GmbH & Co.Inventor: Bernhard Julke

Patent number: 4320828Abstract: A feeder wheel has a hub disk which is centered on and rotatable about an axis, which has a pair of axially oppositely directed faces, and which is formed with a plurality of radially outwardly open, substantially angularly equispaced, and axially throughgoing notches each having a pair of generally radially extending and angularly spaced edges each stepped at a shoulder. Respective feeder arms each having an outer end projecting radially from the disk at the respective notch and an inner end received in the respective notch are each formed with a pair of angularly oppositely projecting flanges engaged axially on the respective shoulders. Fastener bolts extend through the disk and arms at the flanges and shoulders for securing the arms on the disk.Type: GrantFiled: June 5, 1980Date of Patent: March 23, 1982Inventor: Lothar Teske
