Patent number: 10315180Abstract: There is provided a method of producing a localized concentration of energy. The method includes creating at least one shockwave propagating through a non-gaseous medium so as to be incident upon a pocket of gas suspended within the medium. The pocket of gas is spaced from a surface shaped so as, at least partially, to reflect said shockwave in such a way as to direct it onto said gas pocket.Type: GrantFiled: July 1, 2016Date of Patent: June 11, 2019Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker

Patent number: 9984774Abstract: A method of producing a localized concentration of energy includes: creating at least one shockwave propagating through a non-gaseous medium so as first to be incident upon a focusing pocket of fluid within the medium. The focusing pocket of fluid is positioned relative to a differently sized target pocket of gas within the medium, and is arranged to shield the target pocket of gas from the initial shockwave, such that the incidence of the shockwave on the focusing pocket of fluid concentrates the intensity of a shockwave subsequently incident upon the target pocket of gas. An apparatus for producing a localized concentration of energy is also described.Type: GrantFiled: March 6, 2014Date of Patent: May 29, 2018Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker, Matthew Betney

Patent number: 9984775Abstract: A method of producing a localized concentration of energy includes: creating a shockwave propagating through a non-gaseous medium so as to be incident upon a boundary between the non-gaseous medium and a gaseous medium formed by at least one hole in a barrier separating the non-gaseous medium from a gaseous medium. This forms a transverse jet on the other side of the hole which is incident upon a target surface comprising a depression which is spaced from the barrier in the gaseous medium. An apparatus for producing a localized concentration of energy is also described.Type: GrantFiled: March 6, 2014Date of Patent: May 29, 2018Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker

Patent number: 9704603Abstract: A method of impacting liquid droplets onto a surface includes providing a series of liquid droplets, and directing the liquid droplets at a non-planar target surface to cause a shockwave in the droplets upon impact. An apparatus for impacting liquid droplets onto a surface includes a mechanism to produce a series of liquid droplets, and a mechanism to direct the liquid droplets at a non-planar target surface to cause a shockwave in the droplets upon impact. The non-planar target surface is shaped to intensify the shockwave in the droplets.Type: GrantFiled: November 26, 2010Date of Patent: July 11, 2017Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker

Patent number: 9620247Abstract: A method of producing a localized concentration of energy includes providing a series of projectiles and firing the projectiles at a target. An apparatus for producing localized concentration of energy includes: a mechanism to provide a series of projectiles and a mechanism to fire the projectiles at a target. The target is configured such that upon striking the target, a projectile traps and compresses a volume of gas between the projectile and the target. The target and the projectile are also configured such that impact of the projectile onto the target gives rise to a converging shockwave inside the trapped volume of gas.Type: GrantFiled: November 26, 2010Date of Patent: April 11, 2017Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker

Patent number: 9530524Abstract: A method of producing a localized concentration of energy comprises creating at least one shockwave (10) propagating through a non-gaseous medium (8) so as to be incident upon a pocket of gas (2) within the medium (8). The pocket of gas (2) is attached to a surface (6) comprising a depression (4) shaped so as partially to receive the gas pocket (2). An apparatus for producing a localized concentration of energy comprises a non-gaseous medium (8) having therein a pocket of gas (2). The pocket of gas (2) is attached to a surface (6) comprising a depression (4) shaped so as partially to receive the gas pocket (2). The apparatus further comprises means for creating at least one shockwave (10) propagating through the medium (8) so as to be incident upon the pocket of gas (2).Type: GrantFiled: May 9, 2011Date of Patent: December 27, 2016Assignee: OXFORD UNIVERSITY INNOVATION LIMITEDInventors: Yiannis Ventikos, Nicholas Hawker

Publication number: 20130175226Abstract: An acoustic separator comprises: two parallel chamber walls defining a separation chamber therebetween, each chamber wall defining one side of the chamber; inlet means through which fluid can flow into the chamber; and outlet means through which fluid can flow out of the chamber. One of the chamber walls includes a transducer arranged to transmit pressure waves across the chamber towards the other of the chamber walls which in turn is arranged to reflect the pressure waves to set up a standing wave in the chamber. The outlet means defines an opening in one of the sides of the chamber.Type: ApplicationFiled: June 24, 2011Publication date: July 11, 2013Applicant: ISIS INNOVATION LIMITEDInventors: Constantin Coussios, Yiannis Ventikos, Giuliana Trippa, David Taggart
