Patent number: 10420718Abstract: The present invention relates to effervescent compositions which are resistant to water vapor in the atmosphere and to methods of preparing such compositions. In particular, the invention relates to an effervescent composition comprising a co-crystal. The co-crystal comprises an acidic component and a basic component is separate. The co-crystal comprising the acidic component is resistant to water uptake avoiding initiating the effervescence prematurely. Upon dissolution of the co-crystal and the basic component effervescence occurs.Type: GrantFiled: July 2, 2015Date of Patent: September 24, 2019Assignee: University of BradfordInventors: Anant Paradkar, Sudhir Pagire

Patent number: 10234320Abstract: This invention relates to a device and method for measuring the depth of water and sediment deposition in pipes, channels, overland flows and tidal beaches. Sediment deposition may be detrimental to flood control in sewer systems. The invention is specifically concerned with measuring an electrical property such as the conductivity or capacitance in different mediums and therefore quantifying the depths of the different mediums. The measurement of an electrical property such as conductance or capacitance of the medium may also indicate the nature of the medium such as sediment structure, water salinity, and the presence of pollutants. The device includes an array of elongate, substantially mutually parallel electrodes each having a predetermined length, the lengths being incremented stepwise from a shortest electrode to a longest electrode.Type: GrantFiled: February 27, 2018Date of Patent: March 19, 2019Assignee: The University of BradfordInventor: Andrew Nichols

Patent number: 10081847Abstract: The invention provides a method for the production of a metal, the method comprising the steps of mixing an oxide of the metal with a reducing agent comprising a Group II metal or a hydride thereof in the presence of water and/or an organic solvent, heating the mixture of oxide and reducing agent, leaching the resulting material with water; and washing the leached material with a dilute aqueous acid. Typically, the metal is a transition or rare earth metal, the oxide of the metal is an oxide of a transition or rare earth metal, and the reducing agent is selected from calcium or magnesium or the hydrides of calcium and magnesium. The metal is generally obtained at a purity of around 98.5-99.1%, and the method is much quicker than the methods of the prior art and has a much lower carbon footprint, thereby providing an option which is more sustainable, environmentally friendly, and accommodative for industries.Type: GrantFiled: October 17, 2013Date of Patent: September 25, 2018Assignee: UNIVERSITY OF BRADFORDInventors: Jeya Kumari, Raj Patel

Publication number: 20160303257Abstract: The present inventors have harnessed the targeting of nanoparticles to tumour sites, combined with the tumour site specific elevated MMP-14 activity within one conjugate to simultaneously deliver a vascular disrupting agent (VDA) and a MRI contrast agent to a tumour site. The MMP activatable conjugate of the present invention provides both therapeutic and diagnostic functions—and is referred to as a “theranostic”. The theranostic conjugate of the present invention achieves the benefits of tumour site specificity, VDA delivery and MRI contrast agent delivery in a single theranostic conjugate. Consequently, the present invention provides a cancer “theranostic” which improves therapeutic efficacy whilst simultaneously reducing dose-limiting systemic toxicities and provides a tool for rapidly and non-invasively identifying tumour location, monitoring drug delivery and pharmacodynamics.Type: ApplicationFiled: July 25, 2014Publication date: October 20, 2016Applicants: University of Bradford, The Trustees of the Leland Stanford Junior UniversityInventors: Paul Loadman, Robert Falconer, Jason Gill, Jianghong Rao, Heike E.

Publication number: 20130333483Abstract: Dynamic characteristics of a liquid surface (160) are measured by sending acoustic signals (140) to or more target areas (162a-162c) on the liquid surface and receiving said acoustic signals (150a-150c) after reflection from the target area. The detected signals are processed to measure phase shift between the sent and received acoustic signals, the measured phase shift varying over time. The varying phase shift is used to indicate fluctuations over time in the local height of the liquid surface in the target area. The liquid may be water, effluent etc. flowing in a channel or conduit. With suitable calibration, the measured height fluctuations can be used to infer flow characteristics such as surface roughness, wave height, flow depth, flow velocity, volumetric flow rate, shear stress, sediment transport. Using an array of receivers and target areas, additional spatial and temporal characteristics of the surface and the flow can be measured.Type: ApplicationFiled: March 5, 2012Publication date: December 19, 2013Applicant: University of BradfordInventors: Kirill Horoshenkov, Andrew Nichols

Publication number: 20090040985Abstract: A method and apparatus are provided for ad hoc networking over a universal mobile telecommunications system (UMTS). In the method, if user equipment (40A) (such as a mobile phone) is not within normal cell coverage (20), then in an uplink procedure a message which would normally have not be able to be transmitted directly from the User Equipment (40A) to a Base Station (10) is instead forwarded towards the Base Station (10) via one or more intermediate User Equipments (40B). In the method, the user equipment (40A) is arranged to synchronise itself with the Base Station (10) to acquire timeslot and frame synchronisations and thence perform probing activities to build up a list of neighbouring User Equipments. From this list and power and signal to interference calculations the user equipment (40A) is able to work out the relative positions of its neighbours with respect to the Base Station and itself and come to a routing decision for forwarding its message towards the Base Station.Type: ApplicationFiled: August 22, 2006Publication date: February 12, 2009Applicant: UNIVERSITY OF BRADFORDInventors: Ahmed Barnawi, John Graham Gardiner
