  • Patent number: 12115556
    Abstract: A mobile aggregate processing plant for screening material including a chassis and a vibrating screen support frame, and a vibrating screen mounted on the support frame, wherein the vibrating screen has an infeed end and a discharge end, and able to provide at least one material discharge stream therethrough. A feed hopper has a discharge end able to feed a stream of feed material into or onto the vibrating screen. A shredding apparatus is moveable between at least a first in use position above the infeed end of the vibrating screen and/or next to the hopper discharge end, and a second transport position not above the infeed end of the vibrating screen and/or not next to the hopper discharge end.

  • Patent number: 11865582
    Abstract: The present invention provides a combination screening apparatus for screening a mixed material into three graded streams, comprising a disc screen wholly, substantially or partly located within a rotary drum screen. The present invention may be conveniently arranged on a mobile chassis with a simple arrangement of a feed hopper to feed a feed end, and a layered or stacked configuration for the discharge of the so-formed graded streams at a discharge end.

  • Patent number: 11033933
    Abstract: A mobile aggregate processing plant for screening aggregate material comprising a mobile chassis, a vibrating screening unit mounted on the mobile chassis and able to provide at least one aggregate discharge stream therethrough, and an underscreen conveyor located wholly or substantially beneath the vibrating screening unit to wholly or substantially receive said at least one aggregate discharge stream, wherein the underscreen conveyor is driveable in an uphill direction so as to be able to discharge the aggregate discharge stream at a height higher than receiving the aggregate discharge stream, relative to the mobile chassis.

  • Patent number: 9846211
    Abstract: In a structural analysis using NMR techniques, a method for gathering k-value data from frequency encoded spin echoes generated from internal volumes selectively excited by intersecting 90° and 180° slice selective and refocusing RF pulses and subjected to a read gradient for the purpose of quantifying the spatial frequency content of the selected internal volume without contamination by a FID signal, comprising: acquiring spin echo data such that the FID signal generated by imperfections in the 180° slice selective refocusing RF pulse is attenuated by the read gradient such that any remaining FID signal is spatially encoded with higher k-values than the frequency encoded k-values being recorded for subsequent structural analysis while simultaneously providing for t2 t2* and t1 contrast. Other aspects of the invention are disclosed.

  • Publication number: 20140303487
    Abstract: The disclosed invention is a method for detecting indications of the presence of Alzheimer's disease (AD) and related dementia-inducing, motor-control-related pathologies, and other diseases in the human brain using a magnetic-resonance based technique for measuring fine tissue and bone textures. Specifically, the invention focuses on refinements/adaptations to a prior art magnetic resonance fine texture measurement technique that facilitates/enables pushing the detection limits closer to the cellular level, so as to be able to measure the fine scale structures and tissue changes that are known to be characteristic of the neurodegenerative processes involved in the development of these diseases.

  • Patent number: 7303707
    Abstract: A method of processing lignocellulosic material includes the steps of comminuting the material to a size that it can be processed in a hydrothermal pressure vessel, drying the material in moving air to obtain a specific moisture content, packing the material into the vessel and subjecting the material within the vessel to steam under pressure, decompressing the vessel to return the temperature and pressure to ambient and drying the product to specific moisture content; the product so formed can be used for injection moulding or to form panel boards and the like.

  • Patent number: 6993857
    Abstract: A cyclone which includes an upper cylindrical portion opening into the wider end of a lower frustro-conical portion, with a primary air inlet such that the inlet air is substantially tangential to the circumference of the cyclone, and an exhaust outlet at or adjacent the top of the cylindrical portion; a control valve is associated with the exhaust outlet and can be used to partially or completely shut off the outlet; a secondary air inlet is associated with the narrow end of the frustro-conical portion and is provided with an air flow stabilising device adapted to admit a stream of air substantially along the longitudinal axis of the cyclone; also including means for withdrawing processed product from the frustro-conical portion.
