Publication number: 20250037685Abstract: A method and apparatus is disclosed for chime damping. A chime includes a suspension element from which hangs a sound generating element, such as one or more chime tubes or a side wall of a bell chime. A cord retractor is affixed to the suspension element and a center cord is secured to the cord retractor to be windable and unwindable between retracted and extended positions. A damper, a clapper, and/or a windcatcher are affixed to the center cord. Moving the center cord between retracted and extended positions alters the relative position of the damper, the clapper, and/or the windcatcher with respect to the suspension element and the sound generating element to cause noise generation or noise damping.Type: ApplicationFiled: July 24, 2023Publication date: January 30, 2025Inventor: Peter Knight

Patent number: 12189362Abstract: A method for fabricating a component of an abatement apparatus is disclosed. The method comprises: meshing a 3D model representation of a component defining a reaction chamber of an abatement apparatus based on specified component characteristics to define an optimised finite element representation of the component; and fabricating the optimised finite element representation. In this way, a 3D model of a component of an abatement apparatus can be generated from which its performance can be modelled. Particular characteristics of the component may be defined which affect the operation of the abatement apparatus. Those characteristics may then be used to generate the optimized finite element representation of the component which has those characteristics using meshing (it will be appreciated that meshing is the operation of representing a geometric object as a set of finite elements).Type: GrantFiled: May 13, 2019Date of Patent: January 7, 2025Assignee: Edwards LimitedInventors: Andrew James Seeley, Gary Peter Knight, Duncan Michael Price, Mayank Verma

Publication number: 20240179826Abstract: Aspects relate to monitorable plasma torch device components and in particular to monitoring and predictive maintenance of one or more such monitorable plasma torch device components. One aspect provides a monitorable plasma torch device component, the component comprising: a component body and a sacrificial component located in an erosion zone of the component body. The sacrificial component comprises material which differs from the plasma torch device component body and which, on exposure to a plasma torch in a plasma torch device, generates electromagnetic radiation distinct from that of the plasma torch device component body. The distinct electromagnetic radiation generated is indicative of erosion of the monitorable plasma torch device component in the erosion zone. Such a monitorable plasma torch device component can facilitate effective component monitoring which allows for ameliorative action to be taken in the event that degradation of the device component is detected.Type: ApplicationFiled: March 30, 2022Publication date: May 30, 2024Inventors: Gary Peter Knight, Erik Wagenaars, Neil Condon, Simone Magni
