Title: Improvements in or relating to magnetic separators
IPC: B03C1/22
Filed: 1954-11-16
Abstract: 782,840. Magnetic separators. CENTRAL ELECTRICITY AUTHORITY, ELLIS, R. and BARTON CONDUITS, Ltd. Nov. 14, 1955 [Nov. 16, 1954], No. 33137/54. Class 117 In a magnetic separator for removing ferrous matter from discrete material, Fig. 1, an inclined conveyer belt 10 conveys solid fuel 11 immediately beneath a portion of a clearing belt 16 which is fitted with probes 17 of soft iron or similar material and which runs over a preferably electromagnetic driving pulley. Electromagnets 15 are mounted transversely of the belts 10, 16 and each has its neutral point offset from those of adjacent magnets to ensure that the whole width of the fuel is swept by the probes in ar active magnetic field The probes may be arranged in staggered rows transversely of the clearing belt which runs beneath the magnets 15 in the same direction as and slightly faster than the conveyer belt 10. Magnetic material adhering to the probes is delivered from the upper run of the belt 16 into a collecting shoot and the treated fuel passes into a shoot 14. An anti-friction plate 22 which may be of stainless steel may be provided between the magnets 15 and the belt 16. The probes near the edges of the belt 16 may be shorter than those near the centre so as to allow for the concave transverse form of the belt 10, Fig. 3. When the main conveyer belt speed is very high, a length of slow-speed belt 26 may be provided between the interrupted main belt 10a, 10b, Fig. 4, the belt 26 being wider than the main belts to maintain the same carrying capacity. An apron 25 acts as a spreader for the fuel as it passes on to the belt 26, and clearing plates 29 cause excessively large lumps of fuel to be deflected into shoots at the side of the belts. The magnetic system may be applied to existing conveyer systems and where an electromagnetic pulley is already in use this may be used to drive the clearing belts. To maintain a substantially continuous magnetic field for energizing the probes so that they will carry the magnetic material over the pulley it is necessary for the pulley magnet to be energized together with that of the stationary electromagnets.

An apparatus for applying a wrapping 11, e.g. of tin foil around and over the neck of, e.g. a bottle 9, comprises a first upper rotating cylinder 4 having radially reciprocating suction carriers 7 surrounding stationary inserts 15, which together transport the wrapping 11 from a guide 21 past an adhesive applicator (not shown) to a sticking-on position whereupon reciprocation of the carriers 7 occurs and air pressure is substituted for suction to blow the wrapping 11 around the bottle, which may be rotated at the same time. A brush or brushes 13 provide further pressure to secure the wrapping. In a modification a lower rotating cylinder 18 is also incorporated to apply labels 8 to the bottle by a similar operation. The labels 8 and wrapping 11 may have a fixed orientation on the bottles by feeding in the wrapping 11 at an oblique angle to the rotating axis of the cylinder 4, Fig. 2 (not shown). The wrappings 11 are cut from a continuous supply roll 1 by a cutting and feeding device 3 and they may be printed upon.

The level of molten metal (or other conductive liquid) in a non-magnetic vessel 18 Fig. 4 is sensed by a differential transformer 4 having a primary coil 1 and differentially connected secondary coils 2, 3. Secondary coil 3 being positioned nearer to the liquid metal than coil 2 will be affected by eddy currents induced in the liquid metal to a greater degree than coil 2 so that there will be a difference in the induced voltages in the respective coils, the difference voltage being an indication of the said level. The coils are rectangular and have a high length to width ratio, their length being chosen to correspond to the difference between the highest and lowest levels to be detected. The common axis of the coils is perpendicular to the direction of movement of the liquid within the vessel. The coils are force cooled by air via an inlet 6 from a source (not shown).

[Class 72] In an apparatus for the separation of mixed. materials of the kind in which individual pieces of the mixture are passed in sequence past an electrical contacting device and then to a diverting mechanism comprising doors or flaps which are operated automatically, in accordance with the effect of the resistance or conductance of each piece upon an electrical circuit connected with the contact device, to determine the subsequent paths of the individual pieces, the diverting mechanism comprises a member which is moved bodily along fixed guides with a translatory edgewise movement into or out of the path of each piece in accordance with the effect of the piece upon the electrical circuit when passing the contact device. The door 1 is carried in guides fixed to transverse members 12 fixed to the side frames of the machine and is hinged at 3 to a frame 2 which is adjustably attached to one end of a lever 4 by a pin 5. The lever 4 is attached to the frame 6 of the machine by a fulcrum 7 and is rocked about the latter by a thimble 9 and pin 10 attached to the spindle 8 of a solenoid. The position of the plate 1 is such that the trajectory of the individual pieces leaving the belt 14 after contacting with the contact device 16 is such that they will pass over the plate and alight in a shoot 15 or will strike the plate then in an elevated position and drop down on a shoot 18. Instead of flat plates, the latter may be curved and may run in curved guides, and then are attached bv four rods from the corners to a spindle connected to a bell-crank lever. The solenoid operating mechanism may also be arranged below the shoot 15. The plates may be made with strengthening webs at the back and front, may be drilled to lighten them and may be made of suitable light alloys. The apparatus may be used for the separation of coal from shale, or for the treatment of mixtures of, e.g. iron oxide and siliceous material with clays. Specification 421,401 is referred to.
