Patent number: 12115556Abstract: 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.Type: GrantFiled: May 18, 2023Date of Patent: October 15, 2024Assignee: PORTAFILL INTERNATIONAL LIMITEDInventor: Malachy James Rafferty

Patent number: 11865582Abstract: 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.Type: GrantFiled: February 24, 2022Date of Patent: January 9, 2024Assignee: Portafill International LimitedInventor: Malachy James Rafferty

Patent number: 9846211Abstract: 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.Type: GrantFiled: January 5, 2015Date of Patent: December 19, 2017Assignee: Osteotronix Medical PTE LimitedInventors: Timothy W. James, Lance W. Farr, James Rafferty, David Chase

Publication number: 20140303487Abstract: 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.Type: ApplicationFiled: March 12, 2014Publication date: October 9, 2014Inventors: Timothy W. James, Kristin James, Lance W. Farr, David R. Chase, J. Michael Brady, James Rafferty, John P. Heinrich

Patent number: 7303707Abstract: 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.Type: GrantFiled: October 16, 2002Date of Patent: December 4, 2007Assignee: Lignotech Developments LimitedInventors: Karen Millicent Rafferty, legal representative, Andrew James Rafferty, deceased
