  • Patent number: 4858771
    Abstract: Particles are fed for sorting by a radial distributor having an upper surface on which the particles gradually spread arcuately and are displaced radially outwardly, by for example vibration of the distributor, to a lip of the upper surface where they define one or more curved arrays as the fall over the lip. As they fall in free flight trajectory paths the particles present a curved array one particle deep to a separating device arranged to sort the particles according to the degree they possess a particular characteristic.

  • Patent number: 4805706
    Abstract: A rotary impact apparatus comprises an input shaft capable of attachment to an electric drill and arranged to drive an impact assembly through a cone clutch and an output shaft capable of being driven by the impact assembly. The clutch is adjustable by means of a nut and a spring to vary the torque at which drive to the output shaft is disengaged. The impact assembly comprises two rockers adopted to drive the output shaft in respective directions. Each rocker is biased out of engagement with the output shaft by a rocker spring but is unbalanced and rotation of the impact assembly through the clutch by the input shaft creates a centrifugal force on it against the rocker spring whereby it engages the output shaft to rotate the output shaft until resistance to rotation is such that the clutch disengages and rotation of the impact assembly stops.

  • Patent number: 4555385
    Abstract: An introduction process and apparatus is described concerning the continuous elution of a value, i.e. a metal value such as gold, from a particulate carrier by a counterflow of stripping liquid through the pressurized vessel in which the loaded particulate carrier is introduced to the vessel as a low velocity plug in a liquid carrier. The extraction process is also used with the continuous elution process in which the particulate material is extracted from the bottom part of a pressure vessel through a discharge pipe extending therefrom and in which a discharge liquid is introduced into the discharge pipe upstream of the discharge end under such pressure as to maintain a head of the discharge liquid upstream of that location and a flow of the liquid downstream from the location to transport the particulate material through the discharge pipe.

  • Patent number: 4549659
    Abstract: Selection means is provided for particles following a free flight trajectory path, those particles having a preselected characteristic, such as fluorescence under x-ray bombardment, being detected and a signal being transmitted on such detection to electrostatic charging means to locally ionize the atmosphere and thereby charge the detected particle as it passes through the locally ionized atmosphere, the charged particle being deflected from its free flight trajectory path by an electric field. Non-detected and uncharged particles continue in the free flight trajectory path. Particles may be detected in a path having lateral spread by providing detecting means and electrostatic charging means which are together responsive to particles in respective portions of the path.

  • Patent number: 4482097
    Abstract: A rotary apparatus, such as an ore grinding mill, has a wrap-around drive motor secured thereto for rotating the apparatus about a central axis. The drive motor includes a rotor attached to and surrounding the apparatus and a stator surrounding and spaced from the rotor and coupled to the apparatus by anti-friction or journal bearings. Thus, the rotor can rotate relative to the stator yet the stator is supported by the apparatus and the gap between the rotor and stator is maintained substantially uniform at all circumferential locations along the rotor. The journal bearings include a number of wheels or rollers mounted on an annular carrier for the stator and engaging an annular track on the apparatus. The stator has a pair of legs for coupling the stator to a fixed support to prevent rotation of the stator about the central axis relative to the support yet permit small lateral displacements of the stator with the apparatus relative to the axis support.

  • Patent number: 4365717
    Abstract: Feed apparatus and method for feeding objects such as ore rocks in such a way that they are arranged into at least one moving stream of spaced apart objects. The objects are fed onto a first conveyor belt which may have longitudinal channels to arrange the objects into moving rows. The moving objects are projected from end of the belt in free flight path and caught on downwardly moving section of a second belt which passes to a horizontal run via a concavely curved belt section so that objects are stabilized on the second belt by centrifugal action to emerge on horizontal run as one or more fast moving streams.

  • Patent number: 4231478
    Abstract: Method and apparatus for bulk sorting particulate material such as ore rocks. A conveyor belt carries the material in a continuous stream past a detector responsive to a required characteristic to produce a time sequence of detector signals dependent on degree to which material passing the detector possesses that characteristic. The material is projected from the downstream end of the conveyor belt into free flight trajectory and a deflector plate is moved across the face flight path so that material in some zones of the stream is deflected whereas material in other zones is not deflected. A control circuit monitors the detector signals and causes the deflector plate to move so that said zones are determined by the degree to which the material in them possesses the required characteristic.

  • Patent number: 4225089
    Abstract: A fluid flow manifold to deliver pressurized fluid to a series of outlets from a common supply duct has a block body and fluid outlets disposed in linear array along one side of the block. Valves are spread over an opposing side of the body block and connected to the fluid outlet by outlet ducts extending transversely through the block. A supply duct extends longitudinally through the block and delivers fluid to the valves via transfer ducts. The valves are spread in cylindrical array about an axis extending along the linear array of outlets and the outlet ducts converge radially to converge into a linear array defining the fluid outlets such that lengths of all outlet ducts between the valves and the fluid outlets are equal.

  • Patent number: 4210311
    Abstract: A rapid response valve particularly suited for controlling a jet of fluid of variable duration, the valve having a chamber with a valve seat surrounding a valve orifice, a valve member within the chamber movable toward and away from the valve seat, the chamber having an inlet compartment and an outlet compartment, means being provided to effectively balance the fluid pressure on opposite sides of the valve element when in the closed position so that the valve may be rapidly moved to the open position when actuated, means also being provided to create a venturi effect to assist in rapidly returning the valve to its closed position.
