Patent number: 6457576Abstract: The invention relates to a continuous cable conveyor for steep and substantially vertical up-and-down transport, preferably of bulk materials up to extreme transport height which can reach approximately 1,000 m. The transport line is made of extremely resistant fiber cables used as traction means. Guide cables and individual carrier means in the form of buckets are fixed at a distance from each other, over said traction means, at cable clamping connections and endless cable connections designed in a specific manner allowing not only convex returns of the transport line but also concave returns in order to create horizontal or inclined reception and distribution areas. Said transport line is driven, returned, tensioned and guided in a non-positive manner by means of cable pulleys with a possible torsion about the longitudinal axis which can react 180°.Type: GrantFiled: March 13, 2001Date of Patent: October 1, 2002Assignee: Svedala Industri (Deutschland) GmbHInventors: Roland Günther, Jürgen W. Paelke

Patent number: 5161676Abstract: Endless band conveyor (2), the edges of which are equipped with endless cables. Each of the longitudinal edges (6, 7) of the endless band (2) is equipped with projecting catch elements (8) spaced in the longitudinal direction of the band and fastened to an endless cable (12, 14), and on each of the sides of the endless band and over at least some of its length the path of the endless cables is determined by pulleys (15, 16), thus making it possible to suspend the edges of the endless band (2).Type: GrantFiled: July 9, 1991Date of Patent: November 10, 1992Assignee: Universite Joseph FourierInventors: Roland Gunther, Jean M. Terriez

Patent number: 4481695Abstract: A connection unit, which may be undone, for rope ends and more particularly ropes in the form of belts for driving systems, rope conveyors or ropes for lifting loads has, as part of a preferred example, a plate with two rope keepers supported on pins and which keep the rope ends in position thereon by way of stops. These rope end keepers or takeup parts are designed so that they may be turned and locked in position so that, dependent on the direction of turning, the rope may be taken up and made shorter or let off and made longer. The plate, as part of a further example of the invention, has guide parts for positively guiding the rope end and furthermore there is a guiding structure, designed to match the form of a driving sheave so that it may be run thereover.Type: GrantFiled: September 24, 1982Date of Patent: November 13, 1984Assignee: AUMOND-Fordererbau GmbH MaschinenfabrikInventors: Karl H. Koster, Roland Gunther

Patent number: 4367902Abstract: A tool for cutting a material along a path with a liquid jet directed onto the material for hydromechanical or hydraulic mining or for cutting mineral or bituminous material is disclosed. The tool includes a housing having an interior chamber with an opening adjacent the chamber. A nozzle body is mounted to the housing through the opening for swiveling motion about a swivel axis. The nozzle body has a first portion including a cylindrical stem symmetrically disposed about the swivel axis within the chamber and a second portion extending through the opening including a nozzle having a nozzle bore for discharging the liquid jet. A drive, operatively connected to the first portion, is provided for swiveling the nozzle body about the swivel axis.Type: GrantFiled: February 9, 1981Date of Patent: January 11, 1983Assignee: Maschinenfabrik Augsberg-Nurnberg AktiengesellschaftInventors: Karl H. Schwarting, Heinrich Goris, Roland Gunther, Joachim Holz, Kurt Ogorek

Patent number: 4239290Abstract: A hydromatic planer particularly for mining materials in a mining seam comprises a planer housing which advantageously has a cutting and breaking head on each end thereof, each of which includes a substantially identical construction. Each cutting head includes a vertically arranged support member which is mounted on the housing of the planer by a parallel linkage so that it may be moved upwardly and downwardly under the control of an adjustment means such as a fluid pressure operated piston and cylinder combination. Each cutting and breaking head also includes a first substantially vertically arranged support member which is connected by the linkage for upward and downward movement relative to the housing and a second support member which is movable relative to the first and mounted on this first in vertical guides for upward and downward movement.Type: GrantFiled: July 12, 1979Date of Patent: December 16, 1980Assignee: Gutehoffnungshutte Sterkrade AktiengesellschaftInventors: Heinrich Goris, Roland Gunther, Kurt Ogorek, Karl-Heinz Schwarting

Patent number: 4236630Abstract: A subsurface coal bunker operating to receive and discharge coal is structured with an assemblage of nested telescopic container members including one stationary member and a plurality of movable members, with the container members being formed in size in a graduated series with each container member being sized to fit into a next larger container member adjacent thereto. The movable members are telescopically extensible and contractible in order to vary the volume of the assemblage and the bunker assembly is provided with a first belt conveyor for feeding material into the assemblage and a second belt conveyor for transporting material therefrom. A reversible drive mechanism, consisting of hydraulic cylinder devices actuating a system of drive chains and pulleys, is mounted on a support frame of the bunker and operates to drive the movable members between the extended and contracted positions.Type: GrantFiled: September 20, 1978Date of Patent: December 2, 1980Assignee: Gutehoffnungshutte Sterkrade AktiengesellschaftInventors: Gunter Sander, Roland Gunther

Patent number: 4227609Abstract: A bucket conveyor comprises a drive pulley and at least one guide pulley with endless traction cable means engaged over the guide pulley and the drive pulley. A bucket member or a conveyor trough has an axle thereon on each side and with a pulley on the axle. In one embodiment the pulley is pivotal on the axle and in another embodiment the pulley is fixed on the axle. In addition, the construction includes a guide pin on the trough on each side of the axle and the endless traction cable is trained around each guide pin and has a loop engaged over the pulley between the pins. In this manner the endless cable is guided between the drive pulley and the guide pulley and around the pin of each bucket and over the bucket pulley on an axle of the bucket and around the pin on the opposite side of the bucket pulley. The construction is applicable both for a fixed bucket in respect to the traction cable or a bucket that pivots or swings in respect thereto and in which the bucket pulley is rotatable on its bucket axle.Type: GrantFiled: March 9, 1979Date of Patent: October 14, 1980Assignee: Gutehoffnungshutte Sterkrade A.G.Inventors: Roland Gunther, Karl H. Koster

Patent number: 4181363Abstract: A mining method for cutting away hard mineral materials of a mining face, comprises, undercutting the mineral material by directing a liquid jet into the running face to form a mineral slab which overlies the undercutting and breaking the bond of the slab from the main face by striking it with a wedge-shaped impact tool in the undercut area and conveying away the broken-off material. The apparatus for carrying out the mining operation comprises a machine which is adapted to run along the mining face alongside a conveyor for conveying away the material. The machine includes an operating mechanism for moving a breaking head at each end inwardly into the mine face and along the mine face. The breaking head carries a percussion wedge member which may be driven into the mine face.Type: GrantFiled: March 28, 1978Date of Patent: January 1, 1980Assignee: Gutehoffnungshutte Sterkrade A.G.Inventors: Heinrich Goris, Roland Gunther, Kurt Ogorek, Karl-Heinz Schwarting, Wilfried Witulski
