Patent number: 5301811Abstract: An apparatus for separating grain material and for sorting out heavy inclusions from a product flow, particularly stones from gain material, in which the product flow is fed to an inclined layering table and guided so as to be substantially layered thereon. The layering table being acted upon by air flow and oscillated in such a way that the heavy inclusions lying directly thereon are conveyed up the table and guided away separately at the higher end. The feeding of the product flow is effected by way of a feed duct which opens to into the area of the higher end of the table and feeds the product into the separating zone of the product layers as a flow across the widest possible surface area, the separating zone being located in the area of the higher end of the table. The table has air guides for circulating. On an upper side, a closed hood is arranged and on an end side, a product feed portion is arranged. In the middle thereof, an outlet suction portion coupled to the closed hood is arranged.Type: GrantFiled: September 24, 1992Date of Patent: April 12, 1994Assignee: Gebruder Buhler AGInventor: Roman Mueller

Patent number: 5095610Abstract: A method of manufacturing and winding stator core stacks intended for electric motors with internal rotors. Identical sectors are punched and stacked from a sheet metal strip and have spaced pole shoe elements extending radially from a flux return element or core with their free ends projecting inward. The pole shoe elements are given a winding. During the punching process, the pole shoe elements and the flux return element or core are separated from one another and stacked individually, the pole shoe elements being held by an inner ring also punched from the sheet metal strip. Thereafter, windings are applied and finally the wound pole shoes are assembled with the return element to form the stator.The process is especially suitable for manufacturing stators for low-power and miniature motors (less than 1 kW).Type: GrantFiled: August 29, 1990Date of Patent: March 17, 1992Assignee: Gebruder Buhler Nachfolger GmbHInventors: Ulrich Schultz, Willi Brosche

Patent number: 4859482Abstract: For the recovery of the protein from oil seeds, particularly from soy beans, grinding is effected under omission of a suspension liquid, i.e. substantially in dry condition of the oil seed, by applying pressure and friction until the cell walls of the oil seed are opened. This is preferably realized on a friction roller refiner comprising at least two rollers of different speed, i.e. for example on a three-roller-refiner, a five-roller-refiner or also at least two two-roller-refiners. Surprisingly, in this way the expenditure in energy is reduced and the quality of the product is improved.Type: GrantFiled: September 21, 1988Date of Patent: August 22, 1989Assignee: Gebruder Buhler AGInventors: Michel Gavin, Urs Grunder, Karl Ulmer

Patent number: 4730789Abstract: An agitator mill has an arrangement for diminishing the pressure of the attritive elements towards the outlet. This arrangement comprises particularly means for generating a force pointing away from at least one separator opening forming a passage for the product, but retaining the attritive elements within the milling container. This force affects substantially selectively only the attritive elements. According to one embodiment, this force acts upon the attritive elements in counter-direction to the direction of flow of the product. The force may either be a centrifugal force acting selectively onto the relative large mass of the attritive element or a magnetic force acting selectively upon steel balls, iron balls or the like used as attritive elements.Type: GrantFiled: November 17, 1983Date of Patent: March 15, 1988Assignee: Gebruder Buhler AGInventor: Armin Geiger

Patent number: 4721561Abstract: A centrifugal force separator for broken grains, husks, dust and other impurities from air has a pre-separating chamber (2) with a tangential raw gas inlet (1), in which a cylindrical deflecting screen (4) and a clean gas outlet (5) axially adjoining the latter are concentrically arranged. To increase the degree of dust separation at only a slight pressure loss and in the case of an inexpensive construction, and also to enable application in return-air systems in combination with other cereal crop cleaning and processing machines, a pre-separating chamber (X) for an air circulation is provided radially outside the deflecting screen (4), and an air discharge (Y) is provided radially inside the deflecting screen (4), which air discharge (Y) is in flow connection with the pre-separating chamber (X) via air passage channels (17) in the deflecting chamber (4).Type: GrantFiled: November 26, 1985Date of Patent: January 26, 1988Assignee: Gebruder Buhler AGInventors: Hans Oetiker, Franz Reichmuth

Patent number: 4711622Abstract: A pellet mill comprises a die which may rotatably be driven by a suitable drive. At least one press roller engages the inner surface of this die, and material to be pelleted is fed to this press roller by means of a deflector blade situated before. This deflector blade is arranged at least 45.degree. before the related press roller--as seen in the direction of the rotation of the die--so that a free space of at least 45.degree. will result therebetween. Within this free space, the centrifugal force due to the rotation of the die becomes effective and contributes to a better distribution of the material.Type: GrantFiled: June 12, 1985Date of Patent: December 8, 1987Assignee: Gebruder Buhler AGInventor: Hanspeter Schaffner

Patent number: 4708620Abstract: In a die-casting or injection molding machine transducers are provided for generating a signal corresponding to the injection pressure as well as a signal in accordance with the velocity of the ram device, i.e. the injection screw or the injection piston of the machine. The output signals of these transducers are supplied to a calculating stage for calculating the actual injection power. The resulting signal at the output of the calculating stage is fed to an evaluation device, preferably comprising an indicating device, but also a control circuit, if desired.Type: GrantFiled: April 25, 1986Date of Patent: November 24, 1987Assignee: Gebruder Buhler AGInventor: Werner Brugger
