Patent number: 5413222Abstract: A method is disclosed for separating a preselected metal fraction from a stream of discrete particles containing a plurality of metals that are not strongly ferromagnetic. According to this method, a detection zone is established within the stream of particles, and a static magnetic field is established within the detection zone. The static magnetic field so established is of insufficient strength or flux density to induce in the particles of metal in the stream an opposing magnetic field of such strength as to cause the particles in the stream to move. The presence of a particle within the detection zone is detected, and changes in the magnetic flux density of the field are measured as the particle passes through the detection zone.Type: GrantFiled: January 21, 1994Date of Patent: May 9, 1995Inventor: Morris E.

Patent number: 4863040Abstract: Contaminated portions of bulk material are removed from a flow of bulk material with the aid of a flow or drop pipe in a casing that is movable back and forth between a discharge position and a normal flow position. The flow or drop pipe is equipped with baffle plates or bends for sufficiently retarding the free flow of the flowable bulk material to enable a detector and control mechanism to respond to the presence of contaminations and to then move the casing for the discharge of a contaminated portion of bulk material. The movement of the casing of the flow pipe assures that a slide gate or a portion of the casing closes the upper inlet to prevent the further flow of bulk material when the casing is in a discharge position. Due to the retardation of the free flow of the bulk material, it is possible to construct the apparatus with a substantially shorter structural height than was possible heretofore.Type: GrantFiled: December 22, 1987Date of Patent: September 5, 1989Assignee: Varicolor AGInventor: Roland Sandi

Patent number: 4753353Abstract: A conveying device (1) for granular material (2) to be transported has a conveying line (3) which is connected to a suction appliance (7). Along the conveying line (3) is an induction coil (8), which is connected to a control device (10) for a discharge flap (13). By means of the latter, metal particles (2') are separated from the material (2) via a discharge opening (23). The discharge flap (13) and the discharge opening (23) lie inside a separator container (9') of a metal separator (9) through which runs the conveying line (3). The conveying line (3) also has inside the separator container (9') an inflow opening (31) through which the air passing into the container (9') during separation of the metal particles (2') can flow back into the conveying line (3). Since the separator container (9') is directly connected to the conveying line (3), a bypass line can be dispensed with so that a simple and inexpensive line guidance is achieved.Type: GrantFiled: May 27, 1986Date of Patent: June 28, 1988Assignee: Motan Plast-Automation AGInventor: Walter Kramer

Patent number: 4355724Abstract: Apparatus for detecting whether the top panel of a container cap is properly depressed as capped containers are conveyed along a travel path. The apparatus is of the type comprising a floating shoe disposed over the travel path and carrying a proximity sensor.

The floating shoe is mounted for lateral movement and includes guide flanges. The flanges extend generally fore-to-aft and are arranged to be contacted by the caps to shift the shoe laterally so as to position the proximity sensor over the same portions of successive caps. If caps of non-metallic material are being sensed, a metal spring member is carried by the shoe and is arranged to be contacted by the top panel of each cap and assume a spacing from the proximity sensor in accordance with the degree of depression of the top panel. The proximity sensor is directed toward the spring member to sense the latter.Type: GrantFiled: June 18, 1980Date of Patent: October 26, 1982Assignee: Tropicana Products, Inc.Inventors: Frank H.

Patent number: 4311241Abstract: Method for separating clods and the like from potatoes, which includes placing the clods and potatoes on a first belt for transporting the potatoes and clods toward a forward end and positioning a second belt spaced horizontally apart from and vertically lower than the end of the first belt such that potatoes leaving the end travel through the air and land on the second belt. The clods are detected by a detector that includes a magnet and a coil positioned in the field of the magnet. The clods are removed from the system by a normally flaccid inflatable finger positioned between the forward end of the first belt and the second belt. When the detector signals the presence of a clod, air is supplied to the finger causing the stiffening thereof, which deflects the trajectory of the clod causing it to fall between the forward end and the second belt.Type: GrantFiled: November 13, 1979Date of Patent: January 19, 1982Assignee: Lockwood CorporationInventors: F.

Patent number: 4171262Abstract: An apparatus for eliminating metallic contaminations from a fibre transporting duct in spinning preparation, wherein an air stream transports fibre flocks through the duct. At a branching point of the fibre transporting duct leading to a waste duct there is pivotably arranged deflecting means operatively connected with and activated by a drive mechanism.

Variable reluctance sensing apparatus senses changes in the flux. An eddy current test probe is positioned adjacent the magnetic sections. Variable reluctance and eddy current test circuits produce flaw output signals which control apparatus for segregating the rollers. Advantageously the feeding apparatus intermittently deposits successive rollers on the spin rails and intermittently moves the rollers along the rails in end-to-end relationship.Type: GrantFiled: September 6, 1977Date of Patent: May 22, 1979Assignee: Magnetic Analysis CorporationInventors: Edward D.

Patent number: 4116435Abstract: An automatic cue ball separating device is described for billiard tables to separate a metallic containing cue ball from nonmetallic object balls. The cue ball separator includes an induction sensing coil that circumscribes the path of the balls along a return run with the balls passing through an aperture about which the coil loops are formed. The aperture is oblong with the coil mounted at the acute angle of less than 90.degree. with respect to the path of the balls. The cue ball separating device includes an oscillating voltage means that is impedance matched with the induction sensing coil. When the metallic cue ball passes through the aperture, the oscillating electric field is disrupted causing the coil to change impedance. Such inductance change is detected by an electrical circuit which in turn operates a solenoid that engages the cue ball and drives the cue ball from the single file into a cue ball return channel to separate the cue ball from the object balls.Type: GrantFiled: March 18, 1977Date of Patent: September 26, 1978Assignee: Randy D.
