Publication number: 20210331290Abstract: A control system for controlling abrasive blasting apparatus and an abrasive blasting apparatus including such a control system. The control system controls delivery of air and blast media to a blast nozzle of the abrasive blasting apparatus. The control system includes a deadman's switch, the deadman's switch features a user operable control. The user operable control is moveable from a first position, where the control system causes the abrasive blasting apparatus to not deliver air or blast media, to a second position where the control system causes the abrasive blasting apparatus to deliver both air and blast media. When the user operable control is in an intermediate position between the first and second positions, the control system causes the abrasive blasting apparatus to deliver air but not blast media. The control system may have control elements whose state may be sequentially changed by the user operable control as it moves.Type: ApplicationFiled: April 22, 2021Publication date: October 28, 2021Inventors: Ian Mason, John Grimshaw, Michael Carrington Sellars

Patent number: 11092420Abstract: Probes are provided with caps, the caps comprise rolling bearing elements so that the probes can be slid along a surface to be measured, without damaging the surface or wearing away the tip of the probe or a sacrificial cap. The rolling bearing elements can be arranged in a ring around the probe tip, with the plane of the foremost edges of the rolling bearing elements a predetermined distance from the probe tip. The caps can comprise a housing with a grip, to encourage users to grip the cap, which comprises the rolling bearing elements, rather than the probe.Type: GrantFiled: February 27, 2019Date of Patent: August 17, 2021Assignee: Elcometer LimitedInventors: Michael Carrington Sellars, Thomas Partington, Graham Scott Hopper

Publication number: 20200278191Abstract: A surface profile measuring instrument (1), and method, for measuring the surface profile of a substrate (13). The surface profile measuring instrument (1) comprises an electromagnetic probe (8), the electromagnetic probe (8) comprising a probe tip operable to be brought into proximity with a surface of a substrate (13) to be measured, a drive unit (2) operable to generate a low frequency magnetic field penetrating the surface of the substrate (13), a pick up unit (3) operable to detect the strength of the magnetic field and output a magnetic field strength reading and a computation unit (4) operable to determine a surface profile measurement based on the magnetic field strength reading.Type: ApplicationFiled: September 19, 2019Publication date: September 3, 2020Inventors: Neil James Leonard Bennett, Jonathan Bouis, Michael Carrington Sellars, Thomas Partington

Patent number: 9927233Abstract: A coating thickness measuring instrument has a probe for measuring the thickness of a coating applied to a substrate and producing an output relating to the measured thickness; a memory storing calibration data; and a processor arranged to process the output produced by the probe, together with calibration data stored by the memory, and produce a coating thickness measurement. The memory stores at least two sets of calibration data, each set associated with a different surface profile value and a user may select the set of calibration data to be used by the processor according to the surface profile of the substrate on which a measurement is to be made. This enables a user to make coating thickness measurements on substrates with at least two different, known, surface profiles without having to calibrate the instrument specifically for those surfaces.Type: GrantFiled: January 10, 2013Date of Patent: March 27, 2018Assignee: Elcometer LimitedInventors: Michael Carrington Sellars, Joseph J. Walker

Patent number: 9261345Abstract: A surface profile measurement probe comprising two spaced apart points 20 for contacting a convex surface to be measured and a straight edge or surface 22 moveable relative to the two points to enable the straight edge to be brought into contact with a convex surface contacted by the two points. A tip 10 protrudes from and is moveably mounted relative to the straight edge or surface for measuring the profile of a surface contacted by the straight edge.Type: GrantFiled: August 21, 2013Date of Patent: February 16, 2016Assignee: Elcometer LimitedInventors: Colin John Morley, John Michael Whitaker, Michael Carrington Sellars

Publication number: 20150233697Abstract: A measuring instrument, such as a coating thickness measuring instrument, comprises a reader (6) arranged to read information provided on a calibration piece article (7), such as a calibration foil. The reader (6) can be an RFID reader and the information provided in a RFID tag. The information may be used to calibrate the instrument when the instrument is used to measure a property of the calibration piece. The reader (6) may also be used to read information provided on an article to be measured, to identify the article or a location on the article, or on a detachable probe of the instrument.Type: ApplicationFiled: October 9, 2013Publication date: August 20, 2015Applicant: ELCOMETER LIMITEDInventors: Michael Carrington Sellars, Gordon Peter Clark

Publication number: 20080208524Abstract: A surface profile measuring instrument has a means for measuring the profile of a surface and a means for storing measurements produced by the means for measuring the profile of a surface. The instrument may have a tip physically coupled to a sensor. The instrument may also have means for processing the measurements and/or for analysing the measurements. The instrument may be connected to an external device such as a printer and/or to a display unit.Type: ApplicationFiled: February 21, 2008Publication date: August 28, 2008Applicant: ELCOMETER INSTRUMENTS LIMITEDInventors: Ian Carrington Sellars, Peter Ian Baldwin, Philip Anthony May, Colin John Morley, Brian Leslie Williams, Michael Carrington Sellars
